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 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.

Prior to any physical examination, the diagnosis of keratoconus frequently begins with an ophthalmologist's or optometrist's assessment of the person's medical history, particularly the chief complaint and other visual symptoms, the presence of any history of ocular disease or injury which might affect vision, and the presence of any family history of ocular disease. An eye chart, such as a standard Snellen chart of progressively smaller letters, is then used to determine the person's visual acuity. The eye examination may proceed to measurement of the localized curvature of the cornea with a manual keratometer, with detection of irregular astigmatism suggesting a possibility of keratoconus. Severe cases can exceed the instrument's measuring ability. A further indication can be provided by retinoscopy, in which a light beam is focused on the person's retina and the reflection, or reflex, observed as the examiner tilts the light source back and forth. Keratoconus is amongst the ophthalmic conditions that exhibit a scissor reflex action of two bands moving toward and away from each other like the blades of a pair of scissors.

If keratoconus is suspected, the ophthalmologist or optometrist will search for other characteristic findings of the disease by means of slit lamp examination of the cornea. An advanced case is usually readily apparent to the examiner, and can provide for an unambiguous diagnosis prior to more specialized testing. Under close examination, a ring of yellow-brown to olive-green pigmentation known as a Fleischer ring can be observed in around half of keratoconic eyes. The Fleischer ring, caused by deposition of the iron oxide hemosiderin within the corneal epithelium, is subtle and may not be readily detectable in all cases, but becomes more evident when viewed under a cobalt blue filter. Similarly, around 50% of subjects exhibit Vogt's striae, fine stress lines within the cornea caused by stretching and thinning. The striae temporarily disappear while slight pressure is applied to the eyeball. A highly pronounced cone can create a V-shaped indentation in the lower eyelid when the person's gaze is directed downwards, known as Munson's sign. Other clinical signs of keratoconus will normally have presented themselves long before Munson's sign becomes apparent, and so this finding, though a classic sign of the disease, tends not to be of primary diagnostic importance.

A handheld keratoscope, sometimes known as "Placido's disk", can provide a simple noninvasive visualization of the surface of the cornea by projecting a series of concentric rings of light onto the cornea. A more definitive diagnosis can be obtained using corneal topography, in which an automated instrument projects the illuminated pattern onto the cornea and determines its topography from analysis of the digital image. The topographical map indicates any distortions or scarring in the cornea, with keratoconus revealed by a characteristic steepening of curvature which is usually below the centreline of the eye. The technique can record a snapshot of the degree and extent of the deformation as a benchmark for assessing its rate of progression. It is of particular value in detecting the disorder in its early stages when other signs have not yet presented.

Once keratoconus has been diagnosed, its degree may be classified by several metrics:

- The steepness of greatest curvature from 'mild' ( 52 D);

- The morphology of the cone: 'nipple' (small: 5 mm and near-central), 'oval' (larger, below-center and often sagging), or 'globus' (more than 75% of cornea affected);

- The corneal thickness from mild (> 506 μm) to advanced (< 446 μm).

Increasing use of corneal topography has led to a decline in use of these terms.

Although corneal abrasions may be seen with ophthalmoscopes, slit lamp microscopes provide higher magnification which allow for a more thorough evaluation. To aid in viewing, a fluorescein stain that fills in the corneal defect and glows with a cobalt blue-light is generally instilled first.

A careful search should be made for any foreign body, in particular looking under the eyelids. Injury following use of hammers or power-tools should always raise the possibility of a penetrating foreign body into the eye, for which urgent ophthalmology opinion should be sought.

Where trauma is involved, only a funduscopic examination of the back of the eye (retina) is necessary to make the diagnosis. Fluoroscein angiography may show a decrease in blood flow to the areas of whiteness in the retina.

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.

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 the condition appears to slowly subside or diminish on its own, there are no specific treatments for this condition available.

Some precautions include regular visits to an ophthalmologist or optometrist and general testing of the pupil and internal eye through fundamental examinations (listed below). The examinations can determine if any of the muscles of the eye or retina, which is linked to the pupil, have any problems that could relate to the tadpole pupil condition.

Corneal and Retinal Topography: computerized tests that maps the surface of the retina, or the curvature of the cornea.

Fluorescein Angiogram: evaluation of blood circulation in the retina.

Dilated Pupillary Exam: special drops expand the pupil, which then allows doctors to examine the retina.

Slit-Lamp Exam: By shining a small beam of light in the eye, eye doctors can diagnose cataracts, glaucoma, retinal detachment, macular degeneration, injuries to the cornea, and dry eye disease.

Ultrasound: Provides a picture of the eye’s internal structure, and can evaluate ocular tumors, or the retina if its suffering from cataracts or hemorrhages.

Complications are the exception rather than the rule from simple corneal abrasions. It is important that any foreign body be identified and removed, especially if containing iron as rusting will occur.

Occasionally the healed epithelium may be poorly adherent to the underlying basement membrane in which case it may detach at intervals giving rise to recurrent corneal erosions.

In the United States, chemical eye injuries most commonly occur among working-age adults. A 2016 analysis of emergency department visits from 2010-2013 reported over 36,000 visits annually for chemical burns to the eye, with a median age at presentation of 32 years. By individual year of age, 1- and 2-year-old children have the highest incidence of these injuries, with rates approximately 50% higher than the highest-risk adult group (25 years), and 13 times higher than the rate among 7-year-olds. Further research identified laundry detergent pods as a major source of injury among small children.

Thin cut (2-3mm) CT scan with axial and coronal view is the optimal study of choice for orbital fractures.

Plain radiographs, on the other hand, do not sensitively capture blowout fractures. On Water's view radiograph, polypoid mass can be observed hanging from the floor into the maxillary antrum, classically known as teardrop sign, as it usually is in shape of a teardrop. This polypoid mass consists of herniated orbital contents, periorbital fat and inferior rectus muscle. The affected sinus is partially opacified on radiograph. Air-fluid level in maxillary sinus may sometimes be seen due to presence of blood. Lucency in orbits (on a radiograph) usually indicate orbital emphysema.

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.

The center of the cornea shows normal thickness, with an intact central epithelium, but the inferior cornea exhibits a peripheral band of thinning, to about 1–2 mm. The portion of the cornea that is immediately adjacent to the limbus is spared, usually a strip of about 1–2 mm. In PMD we can see high against the rule astigmatism along with horizontal bow ties. The inferior peripheral thinning is seen between the 4 o'clock and 8 o'clock positions.

PMD lacks apical corneal scarring, Rizutti's phenomenon, Munson's sign, and the central corneal thickness is usually normal.

The gold standard diagnostic test for PMD is corneal topography. However, it may not as specific as corneal pachymetry, because corneal topography only evaluates the degree and distribution of surface irregularities on the cornea, not the thickness of the cornea. Corneal topography may show a "crab claw-like" appearance, a finding that is seen in both keratoconus and in pellucid marginal degeneration. Thus, if corneal topography is used for diagnosis, it should be in conjunction with clinical findings of peripheral, inferior corneal thinning.

It may be treated with triamcinolone in some cases. However, in general, there are no treatments for Purtscher's retinopathy. If it is caused by a systemic disease or emboli, then those conditions should be treated.

The need for imaging in patients who have suffered a minor head injury is debated. A non-contrast CT of the head should be performed immediately in all those who have suffered a moderate or severe head injury, an MRI is also an option. Computed tomography (CT) has become the diagnostic modality of choice for head trauma due to its accuracy, reliability, safety, and wide availability. The changes in microcirculation, impaired auto-regulation, cerebral edema, and axonal injury start as soon as head injury occurs and manifest as clinical, biochemical, and radiological changes.

Despite the name, the eye itself is not affected. Blunt force or trauma to the eye socket results in burst capillaries and subsequent haemorrhaging (hematoma). The fatty tissue along with the lack of muscle around the eye socket allows a potential space for blood accumulation. As this blood is reabsorbed, various pigments are released similar to a bruise lending itself to the extreme outward appearance.

The dramatic appearance (discoloration purple black and blue and swelling) does not necessarily indicate a serious injury, and most black eyes resolve within a week. The tissues around the eye are soft and thus bruise easily when pinched against margins of bone which surround the eye socket. The treatment of black eye is the same as that for bruises in other parts of the body – cold compresses during the first twenty-four hours and contrasting hot and cold thereafter. During the process of healing, a black eye can be made less conspicuous by using cosmetics designed to obscure discolorations of the skin. In a severe contusion, blowout of the floor of the orbit may occur, leading to double vision. Such an injury requires surgical correction. A black eye developing after a severe head injury may be a sign of skull fracture.

The treatment method used depends on the cause of the hemorrhage. In most cases, the patient is advised to rest with the head elevated 30–45°, and sometimes to put patches over the eyes to limit movement prior to treatment in order to allow the blood to settle. The patient is also advised to avoid taking medications that cause blood thinning (such as aspirin or similar medications).

The goal of the treatment is to fix the cause of the hemorrhage as quickly as possible. Retinal tears are closed by Laser treatment or cryotherapy, and detached retinas are reattached surgically.

Even after treatment, it can take months for the body to clear all of the blood from the vitreous. In cases of vitreous hemorrhage due to detached retina,long-standing vitreous hemorrhage with a duration of more than 2–3 months, or cases associated with rubeosis iridis or glaucoma, a vitrectomy may be necessary to remove the standing blood in the vitreous.

Common symptoms of vitreous hemorrhage include:

- Blurry vision

- Floaters- faint cobweb-like apparitions floating through the field of vision

- Reddish tint to vision

- Photopsia – brief flashes of light in the peripheral vision

Small vitreous hemorrhage often manifests itself as "floaters". A moderate case will often result in dark streaks in the vision, while dense vitreous hemorrhage can significantly inhibit vision.

Vitreous hemorrhage is diagnosed by identifying symptoms, examining the eye, and performing tests to identify cause. Some common tests include:

- Examination of the eye with a microscope

- Pupil dilation and examination

- An ultrasound examination may be used if the doctor does not have a clear view of the back of the eye

- Blood tests to check for specific causes such as diabetes

- A CT scan to check for injury around the eye

- Referral to a retinal specialist
