The presence of an open globe injuries may be determined by clinical examination and CT. However, full globe exploration with 360-degree removal of the conjunctiva (periotomy), separation of the rectus muscles, and subsequent examination of the sclera remains the most effective way to determine whether or not the globe has been injured. During exploratory surgery, foreign debris may be removed with microsurgical tools by inspection under the operating room microscope. Globe lacerations are typically repaired as far posteriorly as possible to prevent any further deficits in visual acuity. Lacerations posterior to the exposed area are not sutured; attempts to seal these injuries often results in the extrusion of intraocular components. Healing of these injuries occurs naturally by scarring of dorsal orbital fat to the sclera. If a clinically significant increase in intraocular pressure is detected with orbital compartment syndrome, the ophthalmologist may perform an emergency canthotomy on the lateral canthus. Canalicular injuries, as well as lid lacerations, are also commonly repaired in the military hospital setting. Suturing the laceration after the removal of foreign bodies depends on the location of global fissure: 10-0 nylon with cyanoacrylate glue is commonly used on the cornea, and processed human pericardium may be employed if it is surgically available. Globe closure of the limbus and sclera requires 9-0 and 8-0 nylon, respectively.

If damage to the globe is irreparable, the ophthalmologist may conduct a primary enucleation, evisceration (ophthalmology), or exenteration in the combat hospital. 14% of globe injuries sustained during Operation Iraqi Freedom have required enucleation. Implantation of an oculoplastic silicone sphere or similar device commonly follows these procedures.

Post-operative care for patients with blast-related ocular trauma occurs in tertiary care facilities. Patients with closed globe injuries require observation and follow-up examination with an optometrist, including slit lamp microscope and dilated fundus inspection. Those who have been treated for open-globe repairs often experience a delay of post-operative treatment that ranges from 10–14 days after injury. This period is due to the treatment of other life-threatening injuries, as well as the necessity for accurate estimation of visual acuity outside of inflammation due to injury and surgical intervention.

In patients with facial burns, exposure keratopathy, or chronic epiphora, an ophthalmologist may suggest eyelid reconstruction surgery. Depending on the severity of physical trauma sustained, surgical realignment of the extraocular muscles may relieve strabismus. Realignment of the extraocular muscles is also indicated in chronic diplopia that occurs within 20-degrees of the visual field. All patients that have sustained a traumatic brain injury in the absence of ocular trauma are still recommended to obtain examination by an optometrist. Outside of the treatment facility, these patients must monitor any signs of late-onset ocular pathologies secondary to the bTBI, including decreased visual/reading ability and speed, photophobia, blurred vision, reduced accommodation abilities, and headaches.

Methods to prevent intraoperative corneal injuries include

- simple manual closure of the eyelids

- holding the eyelids shut with tape or a general purpose adhesive dressing

- use of a specially designed eyelid occlusion dressing

- use of eye ointment (although this is controversial, see below)

- bio-occlusive dressings

- suture tarsorrhaphy

However, none of the protective strategies are completely effective; vigilance is always required i.e. the eyes need to be inspected regularly throughout surgery to check they are closed.

Multiple complications are known to occur following eye injury: corneal scarring, hyphema, iridodialysis, post-traumatic glaucoma, uveitis cataract, vitreous hemorrhage and retinal detachment. The complications risk is high with retinal tears, penetrating injuries and severe blunt trauma.

Eating certain products and using special routines may help recovery.

Some of the adverse outcomes associated with intra-operative injuries include:

- Increased length of stay. This is due to ophthalmology consults required, associated infections and treatment.

- Increased costs. This is due to increased length of stay, cost of treating the complications.

- Pain and discomfort for the patient. Corneal abrasions are extremely painful for the patient and the treatment consists of drops and ointments applied in the eye which may cause further discomfort for the patient.

Diagnosis is suspected based on lesion circumstances and clinical evidence, most prominently a neurological examination, for example checking whether the pupils constrict normally in response to light and assigning a Glasgow Coma Score. Neuroimaging helps in determining the diagnosis and prognosis and in deciding what treatments to give.

The preferred radiologic test in the emergency setting is computed tomography (CT): it is quick, accurate, and widely available. Follow-up CT scans may be performed later to determine whether the injury has progressed.

Magnetic resonance imaging (MRI) can show more detail than CT, and can add information about expected outcome in the long term. It is more useful than CT for detecting injury characteristics such as diffuse axonal injury in the longer term. However, MRI is not used in the emergency setting for reasons including its relative inefficacy in detecting bleeds and fractures, its lengthy acquisition of images, the inaccessibility of the patient in the machine, and its incompatibility with metal items used in emergency care. A variant of MRI since 2012 is High definition fiber tracking (HDFT).

Other techniques may be used to confirm a particular diagnosis. X-rays are still used for head trauma, but evidence suggests they are not useful; head injuries are either so mild that they do not need imaging or severe enough to merit the more accurate CT. Angiography may be used to detect blood vessel pathology when risk factors such as penetrating head trauma are involved. Functional imaging can measure cerebral blood flow or metabolism, inferring neuronal activity in specific regions and potentially helping to predict outcome. Electroencephalography and transcranial doppler may also be used. The most sensitive physical measure to date is the quantitative EEG, which has documented an 80% to 100% ability in discriminating between normal and traumatic brain-injured subjects.

Neuropsychological assessment can be performed to evaluate the long-term cognitive sequelae and to aid in the planning of the rehabilitation. Instruments range from short measures of general mental functioning to complete batteries formed of different domain-specific tests.

Posterior Vitreous Detachment is diagnosed via dilated eye examination. For some patients the vitreous gel is extremely clear and so it can be hard to see the PVD. In these cases, additional imaging such as Optical Coherence Tomography (OCT) or ocular ultrasound are used.

Therapy is not required or indicated in posterior vitreous detachment, unless there are associated retinal tears, which need to be repaired. In absence of retinal tears, the usual progress is that the vitreous humor will continue to age and liquefy and floaters will usually become less and less noticeable, and eventually most symptoms will completely disappear. Prompt examination of patients experiencing vitreous humor floaters combined with expeditious treatment of any retinal tears has been suggested as the most effective means of preventing certain types of retinal detachments.

The ASCOT probability of survival encapsulates several of the variables measured in the Glasgow Coma Scale but also includes systolic blood pressure, respiration rates upon admission, and anatomic injuries. The ASCOT was found to be the most sensitive tool for determining severity of head injuries in children and is effective in predicting the outcome of injury.

There are several different types of treatment available to those who have suffered a closed-head injury. The treatment type chosen can depend on several factors including the type and severity of injury as well as the effects that injury has on the patient.

The course of treatment differs for each patient and can include several types of treatment, depending on the patient’s specific needs.

Early treatment is vital to recovering lost motor function after an injury, but cognitive abilities can be recovered regardless of time past since injury.

Careful eye examination by an ophthalmologist or optometrist is critical for diagnosing symptomatic VMA. Imaging technologies such as optical coherence tomography (OCT) have significantly improved the accuracy of diagnosing symptomatic VMA.

A new FDA approved drug was released on the market late 2013. Jetrea (Brand name) or Ocriplasmin (Generic name) is the first drug of its kind used to treat vitreomacular adhension.

Mechanism of Action: Ocriplasmin is a truncated human plasmin with proteolytic activity against protein components of the vitreous body and vitreretinal interface. It dissolves the protein matrix responsible for the vitreomacular adhesion.

Adverse drug reactions: Decreased vision, potential for lens sublaxation, dyschromatopsia (yellow vision), eye pain, floaters, blurred vision.

New Drug comparison Rating gave Jetea a 5 indicating an important advance.

Previously, no recommended treatment was available for the patient with mild symptomatic VMA. In symptomatic VMA patients with more significant vision loss, the standard of care is pars plana vitrectomy (PPV), which involves surgically removing the vitreous from the eye, thereby surgically releasing the symptomatic VMA. In other words, vitrectomy induces PVD to release the traction/adhesion on the retina. An estimated 850,000 vitrectomy procedures are performed globally on an annual basis with 250,000 in the United States alone.

A standard PPV procedure can lead to serious complications including small-gauge PPV. Complications can include retinal detachment, retinal tears, endophthalmitis, and postoperative cataract formation. Additionally, PPV may result in incomplete separation, and it may potentially leave a nidus for vasoactive and vasoproliferative substances, or it may induce development of fibrovascular membranes. As with any invasive surgical procedure, PPV introduces trauma to the vitreous and surrounding tissue.

There are data showing that nonsurgical induction of PVD using ocriplasmin (a recombinant protease with activity against fibronectin and laminin) can offer the benefits of successful PVD while eliminating the risks associated with a surgical procedure, i.e. vitrectomy. Pharmacologic vitreolysis is an improvement over invasive surgery as it induces complete separation, creates a more physiologic state of the vitreomacular interface, prevents the development of fibrovascular membranes, is less traumatic to the vitreous, and is potentially prophylactic. As of 2012, ThromboGenics is still developing the ocriplasmin biological agent. Ocriplasmin is approved recently under the name Jetrea for use in the United States by the FDA.view.

An experimental test of injections of perfluoropropane (CF) on 15 symptomatic eyes of 14 patients showed that vitreomacular traction resolved in 6 eyes within 1 month and resolved in 3 more eyes within 6 months.

Unless there is actual trauma to the eye itself (see below), extensive medical attention is generally not needed.

Applying an ice pack will keep down swelling and reduce internal bleeding by constricting the capillaries. Additionally, analgesic drugs (painkillers) can be administered to relieve pain.

An anecdotal remedy for a black eye involves the administering of raw meat to treat the condition - Research on this treatment has yet to find any evidence of this treatment being effective.

Since a major cause of TBI are vehicle accidents, their prevention or the amelioration of their consequences can both reduce the incidence and gravity of TBI. In accidents, damage can be reduced by use of seat belts, child safety seats and motorcycle helmets, and presence of roll bars and airbags. Education programs exist to lower the number of crashes. In addition, changes to public policy and safety laws can be made; these include speed limits, seat belt and helmet laws, and road engineering practices.

Changes to common practices in sports have also been discussed. An increase in use of helmets could reduce the incidence of TBI. Due to the possibility that repeatedly "heading" a ball practicing soccer could cause cumulative brain injury, the idea of introducing protective headgear for players has been proposed. Improved equipment design can enhance safety; softer baseballs reduce head injury risk. Rules against dangerous types of contact, such as "spear tackling" in American football, when one player tackles another head first, may also reduce head injury rates.

Falls can be avoided by installing grab bars in bathrooms and handrails on stairways; removing tripping hazards such as throw rugs; or installing window guards and safety gates at the top and bottom of stairs around young children. Playgrounds with shock-absorbing surfaces such as mulch or sand also prevent head injuries. Child abuse prevention is another tactic; programs exist to prevent shaken baby syndrome by educating about the dangers of shaking children. Gun safety, including keeping guns unloaded and locked, is another preventative measure. Studies on the effect of laws that aim to control access to guns in the United States have been insufficient to determine their effectiveness preventing number of deaths or injuries.

Recent clinical and laboratory research by neurosurgeon Julian Bailes, M.D., and his colleagues from West Virginia University, has resulted in papers showing that dietary supplementation with omega-3 DHA offers protection against the biochemical brain damage that occurs after a traumatic injury. Rats given DHA prior to induced brain injuries suffered smaller increases in two key markers for brain damage (APP and caspase-3), as compared with rats given no DHA. “The potential for DHA to provide prophylactic benefit to the brain against traumatic injury appears promising and requires further investigation. The essential concept of daily dietary supplementation with DHA, so that those at significant risk may be preloaded to provide protection against the acute effects of TBI, has tremendous public health implications.”

Furthermore, acetylcysteine has been confirmed, in a recent double-blind placebo-controlled trial conducted by the US military, to reduce the effects of blast induced mild traumatic brain and neurological injury in soldiers. Multiple animal studies have also demonstrated its efficacy in reducing the damage associated with moderate traumatic brain or spinal injury, and also ischemia-induced brain injury. In particular, it has been demonstrated through multiple studies to significantly reduce neuronal losses and to improve cognitive and neurological outcomes associated with these traumatic events. Acetylcysteine has been safely used to treat paracetamol overdose for over forty years and is extensively used in emergency medicine.

Intraocular pressure should be measured as part of the routine eye examination.

It is usually only elevated by iridocyclitis or acute-closure glaucoma, but not by relatively benign conditions.

In iritis and traumatic perforating ocular injuries, the intraocular pressure is usually low.

The International Statistical Classification of Diseases and Related Health Problems (ICD-10) and the American Psychiatric Association's "Diagnostic and Statistical Manual of Mental Disorders" have set out criteria for post-concussion syndrome (PCS) and post-concussional disorder (PCD), respectively.

The ICD-10 established a set of diagnostic criteria for PCS in 1992. In order to meet these criteria, a patient has had a head injury "usually sufficiently severe to result in loss of consciousness" and then develop at least three of the eight symptoms marked with a check mark in the table at right under "ICD-10" within four weeks.

About 38% of people who suffer a head injury with symptoms of concussion and no radiological evidence of brain lesions meet these criteria. In addition to these symptoms, people that meet the ICD-10 criteria for PCS may fear that they will have permanent brain damage, which may worsen the original symptoms. Preoccupation with the injury may be accompanied by the assumption of a "sick role" and hypochondriasis. The criteria focus on subjective symptoms and mention that neuropsychological evidence of significant impairment is not present. With their focus on psychological factors, the ICD-10 criteria support the idea that the cause of PCS is functional. Like the ICD-10, the ICD-9-CM defines PCS in terms of subjective symptoms and discusses the greater frequency of PCS in people with histories of mental disorders or a financial incentive for a diagnosis.

The DSM-IV lists criteria for diagnosis of PCD in people who have suffered a head trauma with persistent post-traumatic amnesia, loss of consciousness, or post-traumatic seizures. In addition, for a diagnosis of PCD, patients must have neuropsychological impairment as well as at least three of the symptoms marked with a check mark in the table at right under "DSM-IV". These symptoms must be present for three months after the injury and must have been absent or less severe before the injury. In addition, the patient must experience social problems as a result, and must not meet criteria for another disorder that explains the symptoms better.

Neuropsychological tests exist to measure deficits in cognitive functioning that can result from PCS. The Stroop Color Test and the 2&7 Processing Speed Test (which both detect deficits in speed of mental processing) can predict the development of cognitive problems from PCS. A test called the Rivermead Postconcussion Symptoms Questionnaire, a set of questions that measure the severity of 16 different post-concussion symptoms, can be self-administered or administered by an interviewer. Other tests that can predict the development of PCS include the Hopkins Verbal Learning A test (HVLA) and the Digit Span Forward examination. The HVLA tests verbal learning and memory by presenting a series of words and assigning points based on the number recalled, and digit span measures attention efficiency by asking the examinee to repeat back digits spoken by the tester in the same order as they are presented. In addition, neuropsychological tests may be performed to detect malingering (exaggerating or making up symptoms) .

Diagnosis is clinical, seeking a history of eye injury. An important differential diagnosis is Vogt-Koyanagi-Harada syndrome (VKH), which is thought to have the same pathogenesis, without a history of surgery or penetrating eye injury.

Still experimental, skin tests with soluble extracts of human or bovine uveal tissue are said to elicit delayed hypersensitivity responses in these patients. Additionally, circulating antibodies to uveal antigens have been found in patients with SO and VKH, as well as those with long-standing uveitis, making this a less than specific assay for SO and VKH.

Traction caused by VMA is the underlying pathology of an eye disease called symptomatic VMA. There is evidence that symptomatic VMA can contribute to the development of several well-known eye disorders, such as macular hole and macular pucker, that can cause visual impairment, including blindness. It may also be associated with age-related macular degeneration (AMD), diabetic macular edema (DME), retinal vein occlusion, and diabetic retinopathy (DR).

A wide range of factors have been identified as being predictive of PCS, including low socioeconomic status, previous mTBI, a serious associated injury, headaches, an ongoing court case, and female gender. Being older than 40 and being female have also been identified as being predictive of a diagnosis of PCS, and women tend to report more severe symptoms. In addition, the development of PCS can be predicted by having a history of alcohol abuse, low cognitive abilities before the injury, a personality disorder, or a medical illness not related to the injury. PCS is also more prevalent in people with a history of psychiatric conditions such as clinical depression or anxiety before the injury.

Mild brain injury-related factors that increase the risk for persisting post-concussion symptoms include an injury associated with acute headache, dizziness, or nausea; an acute Glasgow Coma Score of 13 or 14; and suffering another head injury before recovering from the first. The risk for developing PCS also appears to be increased in people who have traumatic memories of the injury or expect to be disabled by the injury.

NK is diagnosed on the basis of the patient's medical history and a careful examination of the eye and surrounding area.

With regard to the patient's medical history, special attention should be paid to any herpes virus infections and possible surgeries on the cornea, trauma, abuse of anaesthetics or chronic topical treatments, chemical burns or, use of contact lenses. It is also necessary to investigate the possible presence of diabetes or other systemic diseases such as multiple sclerosis.

The clinical examination is usually performed through a series of assessments and tools:

- General examination of cranial nerves, to determine the presence of nerve damage.

- Eye examinations:

1. Complete eye examination: examination of the eyelids, blink rate, presence of inflammatory reactions and secretions, corneal epithelial alterations.

2. Corneal sensitivity test: performed by placing a cotton wad or cotton thread in contact with the corneal surface: this only allows to determine whether corneal sensitivity is normal, reduced or absent; or using an esthesiometer that allows to assess corneal sensitivity.

3. Tear film function test, such as Schirmer's test, and tear film break-up time.

4. Fluorescein eye stain test, which shows any damage to the corneal and conjunctival epithelium

In an eye with iridocyclitis, (inflammation of both the iris and ciliary body), the involved pupil will be smaller than the uninvolved, due to reflex muscle spasm of the sphincter muscle of the iris.

Generally, conjunctivitis does not affect the pupils.

With acute angle-closure glaucoma, the pupil is generally fixed in mid-position, oval, and responds sluggishly to light, if at all.

Shallow anterior chamber depth may indicate a predisposition to one form of glaucoma (narrow angle) but requires slit-lamp examination or other special techniques to determine it.

In the presence of a "red eye", a shallow anterior chamber may indicate acute glaucoma, which requires immediate attention.

Predisposing factors for Postoperative PVR are preoperative PVR, aphakia, high levels of vitreous proteins, duration of retinal detachment before corrective surgery, the size of the retinal hole or tear, intra-ocular inflammation, vitreous hemorrhage, and trauma to the eye. An equation to calculate the patient's risk for acquiring PVR is:

1 is added if the risk factor is present and 0 if the risk factor is absent. A patient is at a high risk for developing PVR is the PVR score is >6.33.

Because SO is so rarely encountered following eye injury, even when the injured eye is retained, the first choice of treatment may not be enucleation or evisceration, especially if there is a chance that the injured eye may regain some function. Additionally, with current advanced surgical techniques, many eyes once considered nonviable now have a fair prognosis.

However, only if the injured eye has completely lost its vision and has no potential for any visual recovery, prevention of SO is done by enucleation of the injured eye preferably within the first 2 weeks of injury. Evisceration—the removal of the contents of the globe while leaving the sclera and extraocular muscles intact—is easier to perform, offers long-term orbital stability, and is more aesthetically pleasing, i.e., a greater measure of movement of the prosthesis and thus a more natural appearance. There is concern, however, that evisceration may lead to a higher incidence of SO compared to enucleation. Several retrospective studies involving over 3000 eviscerations, however, have failed to identify a single case of SO.

Once SO is developed, Immunosuppressive therapy is the mainstay of treatment. When initiated promptly following injury, it is effective in controlling the inflammation and improving the prognosis. Mild cases may be treated with local application of corticosteroids and pupillary dilators. More severe or progressive cases require high-dose systemic corticosteroids for months to years. Patients who become resistant to corticosteroids or develop side effects of long-term corticosteroid therapy (osteoporosis and pathologic fractures, mental status changes, etc.), may be candidates for therapy with chlorambucil, cyclophosphamide, or ciclosporin.

A black eye, periorbital hematoma, or shiner, is bruising around the eye commonly due to an injury to the face rather than to the eye. The name is given due to the color of bruising. The so-called black eye is caused by bleeding beneath the skin and around the eye. Sometimes a black eye could get worse if not referring to a doctor after a few months, indicating a more extensive injury, even a skull fracture, particularly if the area around both eyes is bruised (raccoon eyes), or if there has been a prior head injury.

Although most black eye injuries are not serious, bleeding within the eye, called a hyphema, is serious and can reduce vision and damage the cornea. In some cases, abnormally high pressure inside the eyeball (ocular hypertension) can also result.

Diagnosis can be difficult as symptoms may be nonspecific. A CT scan of the head is typically recommended if a concern is present. While retinal bleeding is common, it can also occur in other conditions.
