During an acute flare-up, therapy is targeted at reducing the inflammation present, and dilating the pupil. Mydriasis is important, as pupillary constriction is the primary reason for pain. Anti-inflammatory therapy is usually given both systemically, often in the form of flunixin meglumine, and topically, as prednisolone acetate. The mydriatic of choice is atropine. In the periods between acute attacks, no therapy has been shown to be beneficial.

Horses that suffer from this disease can never be considered cured, although they can be managed by careful use of the therapy described above, and fast detection of new flare-ups. If the disease is not properly treated, it will eventually lead to blindness.

Although orbital cellulitis is considered an ophthalmic emergency the prognosis is good if prompt medical treatment is received.

Corticosteroids remain the main treatment modality for IOI. There is usually a dramatic response to this treatment and is often viewed as pathognomonic for this disease. Although response is usually quick, many agree that corticosteroids should be continued on a tapering basis to avoid breakthrough inflammation.

Although many respond to corticosteroid treatment alone, there are several cases in which adjuvant therapy is needed. While many alternatives are available, there is no particular well-established protocol to guide adjuvant therapy. Among the available options there is: surgery, alternative corticosteroid delivery, radiation therapy, non-steroidal anti-inflammatory drugs, cytotoxic agents (chlorambucil, cyclophosphamide), corticosteroid sparing immunosuppressants (methotrexate, cyclosporine, azathioprine), IV immune-globin, plasmapheresis, and biologic treatments (such as TNF-α inhibitors).

Uveitis is typically treated with glucocorticoid steroids, either as topical eye drops (prednisolone acetate) or as oral therapy. Prior to the administration of corticosteroids, corneal ulcers must be ruled out. This is typically done using a fluoresence dye test. In addition to corticosteroids, topical cycloplegics, such as atropine or homatropine, may be used. Successful treatment of active uveitis increases T-regulatory cells in the eye, which likely contributes to disease regression.

In some cases an injection of posterior subtenon triamcinolone acetate may also be given to reduce the swelling of the eye.

Antimetabolite medications, such as methotrexate are often used for recalcitrant or more aggressive cases of uveitis. Experimental treatments with Infliximab or other anti-TNF infusions may prove helpful.

The anti-diabetic drug metformin is reported to inhibit the process that causes the inflammation in uveitis.

In the case of herpetic uveitis, anti-viral medications, such as valaciclovir or aciclovir, may be administered to treat the causative viral infection.

Immediate treatment is very important for someone with orbital cellulitis. Treatment typically involves intravenous (IV) antibiotics in the hospital and frequent observation (every 4–6 hours). Along with this several laboratory tests are run including a complete blood count, differential, and blood culture.

- Antibiotic therapy – Since orbital cellulitis is commonly caused by "Staphylococcus" and "Streptococcus" species both penicillins and cephalosporins are typically the best choices for IV antibiotics. However, due to the increasing rise of MRSA (methicillin-resistant "Staphylococcus aureus") orbital cellulitis can also be treated with Vancomycin, Clindamycin, or Doxycycline. If improvement is noted after 48 hours of IV antibiotics, healthcare professions can then consider switching a patient to oral antibiotics (which must be used for 2–3 weeks).

- Surgical intervention – An abscess can threaten the vision or neurological status of a patient with orbital cellulitis, therefore sometimes surgical intervention is necessary. Surgery typically requires drainage of the sinuses and if a subperiosteal abscess is present in the medial orbit, drainage can be performed endoscopically. Post-operatively, patients must follow up regularly with their surgeon and remain under close observation.

The prognosis is generally good for those who receive prompt diagnosis and treatment, but serious complication including cataracts, glaucoma, band keratopathy, macular edema and permanent vision loss may result if left untreated. The type of uveitis, as well as its severity, duration, and responsiveness to treatment or any associated illnesses, all factor into the outlook.

In cases of viral adenoiditis, treatment with analgesics or antipyretics is often sufficient. Bacterial adenoiditis may be treated with antibiotics, such as amoxicillin - clavulanic acid or a cephalosporin. In case of adenoid hypertrophy, adenoidectomy may be performed to remove the adenoid.

Treatment of THS includes immunosuppressives such as corticosteroids (often prednisolone) or steroid-sparing agents (such as methotrexate or azathioprine).

Radiotherapy has also been proposed.

For unconfirmed acute sinusitis, intranasal corticosteroids have not been found to be better than a placebo either alone or in combination with antibiotics. For cases confirmed by radiology or nasal endoscopy, treatment with corticosteroids alone or in combination with antibiotics is supported. The benefit, however, is small.

There is only limited evidence to support short treatment with oral corticosteroids for chronic rhinosinusitis with nasal polyps.

The prognosis of THS is usually considered good. Patients usually respond to corticosteroids, and spontaneous remission can occur, although movement of ocular muscles may remain damaged. Roughly 30–40% of patients who are treated for THS experience a relapse.

Recommended treatments for most cases of sinusitis include rest and drinking enough water to thin the mucus. Antibiotics are not recommended for most cases.

Breathing low-temperature steam such as from a hot shower or gargling can relieve symptoms. There is tentative evidence for nasal irrigation. Decongestant nasal sprays containing oxymetazoline may provide relief, but these medications should not be used for more than the recommended period. Longer use may cause rebound sinusitis. It is unclear if nasal irrigation, antihistamines, or decongestants work in children with acute sinusitis.

Steroid therapy is also controversial in many cases of CST. However, corticosteroids are absolutely indicated in cases of pituitary insufficiency. Corticosteroid use may have a critical role in patients with Addisonian crisis secondary to ischaemia or necrosis of the pituitary that complicates CST.

Broad-spectrum intravenous antibiotics are used until a definite pathogen is found.

1. Nafcillin 1.5 g IV q4h

2. Cefotaxime 1.5 to 2 g IV q4h

3. Metronidazole 15 mg/kg load followed by 7.5 mg/kg IV q6h

Vancomycin may be substituted for nafcillin if significant concern exists for infection by methicillin-resistant "Staphylococcus aureus" or resistant "Streptococcus pneumoniae". Appropriate therapy should take into account the primary source of infection as well as possible associated complications such as brain abscess, meningitis, or subdural empyema.

All people with CST are usually treated with prolonged courses (3–4 weeks) of IV antibiotics. If there is evidence of complications such as intracranial suppuration, 6–8 weeks of total therapy may be warranted.

All patients should be monitored for signs of complicated infection, continued sepsis, or septic emboli while antibiotic therapy is being administered.

A surgeon trained to do eyelid surgery, such as a plastic surgeon or ophthalmologist, is required to decide and perform the appropriate surgical procedure. The following procedures have been described for blepharochalasis:

- External levator aponeurosis tuck

- Blepharoplasty

- Lateral canthoplasty

- Dermis fat grafts

These are used to correct atrophic blepharochalasis after the syndrome has run its course.

Medical management may involve immunosuppressive drugs such as methotrexate, corticosteroids, cyclophosphamide, and azathioprine. No randomized controlled trials have yet been conducted to evaluate such treatments, so the benefits have not been clearly established.

Treatment and prognosis depend on the underlying condition. For example, in thiamine deficiency, treatment would be the immediate administration of vitamin B1.

All patients should follow-up with an ophthalmologist within 1 week of the fracture. To prevent orbital emphysema, patients are advised to avoid blowing of the nose. Nasal decongestants are commonly used. It is also common practice to administer prophylactic antibiotics when the fracture enters a sinus, although this practice is largely anecdotal. Amoxicillin-clavulanate and azithromycin are most commonly used. Oral corticosteroids are used to decrease swelling.

Since pericoronitis is a result of inflammation of the pericoronal tissues of a partially erupted tooth, management can include applying pain management gels for the mouth consisting of Lignocaine, a numbing agent. Definitive treatment can only be through preventing the source of inflammation. This is either through improved oral hygiene or by removal of the plaque stagnation areas through tooth extraction or gingival resection. Often acute symptoms of pericoronitis are treated before the underlying cause is addressed.

When possible, immediate definitive treatment of acute pericoronitis is recommended because surgical treatment has been shown to resolve the spread of the infection and pain, with a quicker return of function. Also immediate treatment avoids overuse of antibiotics (preventing antibiotic resistance).

However, surgery is sometimes delayed in an area of acute infection, with the help of pain relief and antibiotics, for the following reasons:

- Reduces the risk of causing an infected surgical site with delayed healing (e.g. osteomyelitis or cellulitis).

- Avoids reduced efficiency of local anesthetics caused by the acidic environment of infected tissues.

- Resolves the limited mouth opening, making oral surgery easier.

- Patients may better cope with the dental treatment when free from pain.

- Allows for adequate planning with correctly allocated procedure time.

Firstly, the area underneath the operculum is gently irrigated to remove debris and inflammatory exudate. Often warm saline is used but other solutions may contain hydrogen peroxide, chlorhexidine or other antiseptics. Irrigation may be assisted in conjunction with Debridement (removal of plaque, calculus and food debris) with periodontal instruments. Irrigation may be enough to relieve any associated pericoronal abscess; otherwise a small incision can be made to allow drainage.

Smoothing an opposing tooth which bites into the affected operculum can eliminate this source of trauma.

Home care may involve regular use of hot salt water mouthwashes/mouth baths.

Following treatment, if there are systemic signs and symptoms, such as facial or neck swelling, cervical lymphadenitis, fever or malaise, a course of oral antibiotics is often prescribed. Common antibiotics used are from the β-lactam antibiotic group, clindamycin and metronidazole.

If there is dysphagia or dyspnoea (difficulty swallowing or breathing), then this usually means there is a severe infection and an emergency admission to hospital is appropriate so that intravenous medications and fluids can be administered and the threat to the airway monitored. Sometimes semi-emergency surgery may be arranged to drain a swelling that is threatening the airway.

Trochleitis is diagnosed based on three criteria: 1) demonstration of inflammation of superior oblique tendon/ trochlea region, 2) periorbital pain and tenderness to palpation in the area of the sore trochlea, and 3) worsening of pain on attempted vertical eye movement, particularly with adduction of the eye. It is important to identify trochleitis because it is a treatable condition and the patient can benefit much from pain relief. Treatment consists of a single injection of corticosteroids to the affected peritrochlear region. A specific "cocktail" consisting of 0.5 ml of depomedrol (80 mg/ml) and 0.5 ml of 2% lidocaine can be injected into the trochlea; immediate relief due to the effects of the local anesthetic indicates successful placement. However, great care must be taken as the injection is in the region of several arteries, veins and nerves. The needle should not be too small (so as not to penetrate tiny structures), the surgeon should draw back on the syringe (to ensure not have pierced a vessel), the lidocaine should not contain epinephrine (which could cause vasospasm), and the pressure of the injection must always be controlled. Only a limited number of injections can be made as they would otherwise lead to muscle atrophy. Diagnosis can be confirmed by response to this treatment; pain and swelling are expected to disappear in 48–72 hours. Some patients experience recurrence of trochleitis.

No treatment required. It is standard practice for men with infertility and category IV prostatitis to be given a trial of antibiotics and/or anti-inflammatories, although evidence of efficacy are weak. Since signs of asymptomatic prostatic inflammation may sometimes be associated with prostate cancer, this can be addressed by tests that assess the ratio of free-to-total PSA. The results of these tests were significantly different in prostate cancer and category IV prostatitis in one study.

Affected individuals may benefit from autologous fat transfer or fat grafts to restore a more normal contour to the face. However, greater volume defects may require microsurgical reconstructive surgery which may involve the transfer of an island parascapular fasciocutaneous flap or a free flap from the groin, rectus abdominis muscle (Transverse Rectus Abdominis Myocutaneous or "TRAM" flap) or latissimus dorsi muscle to the face. Severe deformities may require additional procedures, such as pedicled temporal fascia flaps, cartilage grafts, bone grafts, orthognathic surgery, and bone distraction. The timing of surgical intervention is controversial; some surgeons prefer to wait until the disease has run its course while others recommend early intervention.

Surgery is indicated if there is enophthalmos greater than 2 mm on imaging, Double vision on primary or inferior gaze, entrapment of extraocular muscles, or the fracture involves greater than 50% of the orbital floor. When not surgically repaired, most blowout fractures heal spontaneously without significant consequence.

Surgical repair of a "blowout" is rarely undertaken immediately; it can be safely postponed for up to two weeks, if necessary, to let the swelling subside. Surgery to place an orbital implant leaves little or no scarring and the recovery period is usually brief. Hopefully, the surgery will provide a permanent cure, but sometimes it provides only partial relief from double vision or a sunken eye. Reconstruction is usually performed with a titanium mesh or porous polyethylene through a transconjunctival or subciliary incision. More recently, there has been success with endoscopic, or minimally invasive, approaches.

Inflammation is usually indicated by adding the suffix "", as shown below. However, some conditions such as asthma and pneumonia do not follow this convention. More examples are available at list of types of inflammation.
