For the allergic type, cool water poured over the face with the head inclined downward constricts capillaries, and artificial tears sometimes relieve discomfort in mild cases. In more severe cases, nonsteroidal anti-inflammatory medications and antihistamines may be prescribed. Persistent allergic conjunctivitis may also require topical steroid drops.

Viral conjunctivitis usually resolves on its own and does not require any specific treatment. Antihistamines (e.g., diphenhydramine) or mast cell stabilizers (e.g., cromolyn) may be used to help with the symptoms. Povidone iodine has been suggested as a treatment, but as of 2008 evidence to support it was poor.

Oral Antibiotics: Ophthalmologists or optometrists may prescribe a low-dose, oral antibiotic such as Doxycycline.

Topical Antibiotics: If prescribed, topical creams or ointments can be applied after the cleansing of the lid margin. A small amount of antibiotic ophthalmic ointment is spread along the lid fissure with a swab or fingertip, while the eyes are closed. It is prescribed for use prior to bedtime to avoid blurred vision. Another method to reduce side effects of blepharitis are antibiotics such as erythromycin or sulfacetamide, which are used via eye drops, creams, or ointments on the eyelid margin. blepharitis caused by Demodex mites can be treated using a diluted solution of tea tree oil, via application by a cotton swab, for 5–10 minutes per day.

Steroid eyedrops/ointments: Eye drops or ointments containing corticosteroids are frequently used in conjunction with antibiotics and can reduce eyelid inflammation.

Ligneous conjunctivitis may be managed by topical treatments of plasminogen, topical and subconjunctival fresh frozen plasma, and fibrinolytic therapy.

Warm Compresses: "Soften lid margin debris and oils" by placing a very warm wet compress such as a clean, warm, wet washcloth over the closed eyelids for five minutes. Re-wet and reapply it as it cools. This warms, softens, and loosens crusty and oily eyelid gland deposits.

Eyelid Hygiene: "Remove lid margin debris" immediately after the warm compresses by gently washing the eyelids with a warm, wet, soapy washcloth to remove accumulated debris. Use a diluted, hypoallergenic baby shampoo. Gently rub along the lid margins, keeping the eyes shut. Too much soap or shampoo may remove the essential oil layer of the eyes' tear film and create further stress to the eye, as well as dry eye discomfort. A moist cotton swab soaked in a cup of water and baby shampoo may be used to rub along the lid margins while tilting the lid outward with the other hand to avoid this problem. Finally, rinse the eyelid with warm water and gently dry with a towel. "Eye make-up" should not be used while inflammation is present. "Dandruff shampoo" can be helpful if dandruff is contributing to blepharitis and may relieve blepharitis symptoms.

Prophylaxis needs antenatal, natal, and post-natal care.

- Antenatal measures include thorough care of mother and treatment of genital infections when suspected.

- Natal measures are of utmost importance as mostly infection occurs during childbirth. Deliveries should be conducted under hygienic conditions taking all aseptic measures. The newborn baby's closed lids should be thoroughly cleansed and dried.

- If it is determined that the cause is due to a blocked tear duct, a gentle palpation between the eye and the nasal cavity may be used to clear the tear duct. If the tear duct is not cleared by the time the newborn is one year old, surgery may be required.

- Postnatal measures include:

- Chemical ophthalmia neonatorum is a self-limiting condition and does not require any treatment.

- Gonococcal ophthalmia neonatorum needs prompt treatment to prevent complications. Topical therapy should include

Systemic therapy: Newborns with gonococcal ophthalmia neonatorum should be treated for seven days with one of the following regimens ceftriaxone, cefotaxime, ciprofloxacin, crystalline benzyl penicillin

- Other bacterial ophthalmia neonatorum should be treated by broad spectrum antibiotics drops and ointment for two weeks.

- Neonatal inclusion conjunctivitis caused by Chlamydia trachomatis responds well to topical tetracycline 1% or erythromycin 0.5% eye ointment QID for three weeks. However systemic erythromycin should also be given since the presence of chlamydia agents in conjunctiva implies colonization of upper respiratory tract as well. Both parents should also be treated with systemic erythromycin.

- Herpes simplex conjunctivitis should be treated with intravenous acyclovir for a minimum of 14 days to prevent systemic infection.

Antibiotic ointment is typically applied to the newborn's eyes within 1 hour of birth as prevention against gonococcal ophthalmia. This maybe erythromycin, tetracycline, or silver nitrate.

Herpetic stromal keratitis is treated initially with prednisolone drops every 2 hours

accompanied by a prophylactic antiviral drug: either topical antiviral or an oral agent such as acyclovir or valacyclovir. The prednisolone drops are tapered every 1–2 weeks depending on the degree of clinical improvement. Topical antiviral medications are not absorbed by the cornea through an intact epithelium, but orally administered acyclovir penetrates an intact cornea and anterior chamber. In this context, oral acyclovir might benefit the deep corneal inflammation of disciform keratitis.

Epithelial keratitis is treated with topical antivirals, which are very effective with low incidence of resistance. Treatment of the disease with topical antivirals generally should be continued for 10–14 days. Aciclovir ophthalmic ointment and Trifluridine eye drops have similar effectiveness but are more effective than Idoxuridine and Vidarabine eye drops. Oral acyclovir is as effective as topical antivirals for treating epithelial keratitis, and it has the advantage of no eye surface toxicity. For this reason, oral therapy is preferred by some ophthalmologists.

Ganciclovir and brivudine treatments were found to be equally as effective as acyclovir in a systematic review.

Valacyclovir, a pro-drug of acyclovir likely to be just as effective for ocular disease, can cause thrombotic thrombocytopenic purpura/Hemolytic-uremic syndrome in severely immunocompromised patients such as those with AIDS; thus, it must be used with caution if the immune status is unknown.

Topical corticosteroids are contraindicated in the presence of active herpetic epithelial keratitis; patients with this disease who are using systemic corticosteroids for other indications should be treated aggressively with systemic antiviral therapy.

The effect of interferon with an antiviral agent or an antiviral agent with debridement needs further assessment.

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.

Treatment of mucositis is mainly supportive. Oral hygiene is the mainstay of treatment; patients are encouraged to clean their mouth every four hours and at bedtime, more often if the mucositis becomes worse.

Water-soluble jellies can be used to lubricate the mouth. Salt mouthwash can soothe the pain and keep food particles clear so as to avoid infection. Patients are also encouraged to drink plenty of liquids, at least three liters a day, and avoid alcohol. Citrus fruits, alcohol, and foods that are hot are all known to aggravate mucositis lesions. Medicinal mouthwashes may be used such as Chlorhexidine gluconate and viscous Lidocaine for relief of pain. Palifermin is a human KGF (keratinocyte growth factor) that has shown to enhance epithelial cell proliferation, differentiation, and migration. Experimental therapies have been reported, including the use of cytokines and other modifiers of inflammation (e.g., IL-1, IL-11, TGF-beta3), amino acid supplementation (e.g., glutamine), vitamins, colony-stimulating factors, cryotherapy, and laser therapy.

Symptomatic relief of the pain of oral mucositis may be provided by barrier protection agents such as concentrated oral gel products (e.g. Gelclair). Caphosol is a mouth rinse which has been shown to prevent and treat oral mucositis caused by radiation and high-dose chemotherapy. MuGard is a FDA-cleared mucoadhesive oral protectant, developed by Access Pharmaceuticals, Inc., that is designed to form a protective hydrogel coating over the oral mucosa while a patient is undergoing chemotherapy and/or radiotherapy cancer treatments to the head and neck. Additionally, the efficacy of MuGard for the prevention or treatment of mucositis has been tested by a prospective, randomized clinical trial in which 43% of head and neck cancer patients using MuGard prophylactically never got oral mucositis.

NeutraSal is an FDA-cleared calcium phosphate mouth rinse which has been shown in an open-label, observational registry trial to prevent and reduce the severity of oral mucositis caused by radiation and high-dose chemotherapy. In the trial, 56% of the radiotherapy patients reported 0 (WHO score) or no mucositis, which is significantly lower than historical rates. Another super saturated calcium phosphate rinse on the market and cleared by the FDA is the US based SalivaMAX. The Mayo Clinic has been testing the antidepressant doxepin in a mouthwash to help treat symptoms.

In 2011, the FDA cleared episil oral liquid for the management and relief of pain of oral lesions with various etiologies, including oral mucositis/stomatitis which may be caused by chemotherapy or radiation therapy. The transformative mechanism of action of episil creates a lipid membrane that mechanically bonds to the oral cavity mucosa to coat and soothe inflammation and ulcerations, and blanket painful lesions. In a multicenter, randomized, double-blind, single-dose study involving 38 head and neck cancer patients with oral mucositis (WHO grades 2-3) undergoing radiation therapy, episil clinically demonstrated fast-acting relief that lasted up to 8 hours. Episil oral liquid is marketed in the US by Cangene.

In a 2012 randomized controlled pilot study involving pediatric patients, topical application of honey was found to reduce recovery time compared to benzocaine gel in grade 2 and 3 chemotherapy-induced oral mucositis to a degree that was statistically significant. In grade 3 oral mucositis, honey was as effective as a mixture of honey, olive oil and propolis, while both treatments were found to reduce recovery time compared to the benzocaine control.

Clinical research is ongoing in oral mucositis. A recent phase 2 exploratory trial in oral mucositis reported that dusquetide, a unique innate immune modulator with a mechanism that potentially addresses each of the phases of OM pathophysiology, is able to reduce the duration of severe oral mucositis, as well as reducing the incidence of infections. Dusquetide is being developed by Soligenix, Inc.

Oral candidiasis can be treated with topical anti-fungal drugs, such as nystatin, miconazole, Gentian violet or amphotericin B.

Underlying immunosuppression may be medically manageable once it is identified, and this helps prevent recurrence of candidal infections.

Patients who are immunocompromised, either with HIV/AIDS or as a result of chemotherapy, may require systemic treatment with oral or intravenous administered anti-fungals.

If candidiasis is secondary to corticosteroid or antibiotic use, then use may be stopped, although this is not always a feasible option. Candidiasis secondary to the use of inhaled steroids may be treated by rinsing out the mouth with water after taking the steroid. Use of a spacer device to reduce the contact with the oral mucosa may greatly reduce the risk of oral candidiasis.

In recurrent oral candidiasis, the use of azole antifungals risks selection and enrichment of drug-resistant strains of candida organisms. Drug resistance is increasingly more common and presents a serious problem in persons who are immunocompromised.

Prophylactic use of antifungals is sometimes employed in persons with HIV disease, during radiotherapy, during immunosuppressive or prolonged antibiotic therapy as the development of candidal infection in these groups may be more serious.

The candidal load in the mouth can be reduced by improving oral hygiene measures, such as regular toothbrushing and use of anti-microbial mouthwashes. Since smoking is associated with many of forms of oral candidiasis, cessation may be beneficial.

Antibiotics are commonly used to prevent secondary bacterial infection. There are no specific antiviral drugs in common use at this time for FVR, although one study has shown that ganciclovir, PMEDAP, and cidofovir hold promise for treatment. More recent research has indicated that systemic famciclovir is effective at treating this infection in cats without the side effects reported with other anti-viral agents. More severe cases may require supportive care such as intravenous fluid therapy, oxygen therapy, or even a feeding tube. Conjunctivitis and corneal ulcers are treated with topical antibiotics for secondary bacterial infection.

Lysine is commonly used as a treatment, however in a 2015 systematic review, where the authors investigated all clinical trials with cats as well as "in vitro" studies, concluded that lysine supplementation is not effective for the treatment or prevention of feline herpesvirus 1 infection.

Good denture hygiene involves regular cleaning of the dentures, and leaving them out of the mouth during sleep. This gives the mucosa a chance to recover, while wearing a denture during sleep is often likened to sleeping in one's shoes. In oral candidiasis, the dentures may act as a reservoir of Candida species, continually reinfecting the mucosa once antifungal medication is stopped. Therefore, they must be disinfected as part of the treatment for oral candidiasis. There are commercial denture cleaner preparations for this purpose, but it is readily accomplished by soaking the denture overnight in a 1:10 solution of sodium hypochlorite (Milton, or household bleach). Bleach may corrode metal components, so if the denture contains metal, soaking it twice daily in chlorhexidine solution can be carried out instead. An alternative method of disinfection is to use a 10% solution of acetic acid (vinegar) as an overnight soak, or to microwave the dentures in 200mL water for 3 minutes at 650 watts. Antifungal medication can also be applied to the fitting surface of the denture before it is put back in the mouth. Other problems with the dentures, such as inadequate occlusal vertical dimension may also need to be corrected in the case of angular cheilitis.

Treatment is based on the prescription and use of the proper antibiotics depending on the strain of the ureaplasma.

Because of its multi-causative nature, initial treatment strategies involve using a broad range antibiotic that is effective against chlamydia (such as doxycycline). It is imperative that both the patient and any sexual contacts be treated. Women infected with the organisms that cause NGU may develop pelvic inflammatory disease. If symptoms persist, follow-up with a urologist may be necessary to identify the cause.

According to a study, tinidazole used with doxycycline or azithromycin may cure NGU better than when doxycycline or azithromycin is used alone.

If left untreated, complications include epididymitis and infertility. Consistent and correct use of latex condoms during sexual activity greatly reduces the likelihood of infection.

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.

Mast cell stabilizers can help people with allergic conjunctivitis. They tend to have delayed results, but they have fewer side-effects than the other treatments and last much longer than those of antihistamines. Some people are given an antihistamine at the same time so that there is some relief of symptoms before the mast cell stabilizers becomes effective. Doctors commonly prescribe lodoxamide and nedocromil as mast cell stabilizers, which come as eye drops.

A mast cell stabilizer is a class of non-steroid controller medicine that reduces the release of inflammation-causing chemicals from mast cells. They block a calcium channel essential for mast cell degranulation, stabilizing the cell, thus preventing the release of histamine. Decongestants may also be prescribed. Another common mast cell stabilizer that is used for treating allergic conjunctivitis is sodium cromoglicate.

Antihistamines such as diphenhydramine and chlorpheniramine are commonly used as treatment. People treated with H1 antihistamines exhibit reduced production of histamine and leukotrienes as well as downregulation of adhesion molecule expression on the vasculature which in turn attenuates allergic symptoms by 40–50%.

Dual-action medications are also prescribed frequently. Olopatadine (Patanol) and ketotifen fumarate (Alaway or Zaditor) both provide protection by acting as an antihistamine and a mast cell stabilizer together. Patanol is a prescription medication, whereas ketotifen fumarate is not.

A systematic review of 30 trials, with 17 different treatment comparisons found that all topical antihistamines and mast cell stabilizers included for comparison were effective in reducing symptoms of seasonal allergic conjunctivitis. There was not enough evidence to determine differences in long-term efficacy among the treatments.

Many of the eye drops can cause burning and stinging, and have side-effects. Proper eye hygiene can improve symptoms, especially with contact lenses. Avoiding precipitants, such as pollen or mold can be preventative.

Antihistamine drugs can be taken orally and nasally to control symptoms such as sneezing, rhinorrhea, itching, and conjunctivitis.

It is best to take oral antihistamine medication before exposure, especially for seasonal allergic rhinitis. In the case of nasal antihistamines like azelastine antihistamine nasal spray, relief from symptoms is experienced within 15 minutes allowing for a more immediate 'as-needed' approach to dosage.

Ophthalmic antihistamines (such as azelastine in eye drop form and ketotifen) are used for conjunctivitis, while intranasal forms are used mainly for sneezing, rhinorrhea, and nasal pruritus.

Antihistamine drugs can have undesirable side-effects, the most notable one being drowsiness in the case of oral antihistamine tablets. First-generation antihistamine drugs such as diphenhydramine cause drowsiness, but second- and third-generation antihistamines such as cetirizine and loratadine are less likely to cause this problem.

Pseudoephedrine is also indicated for vasomotor rhinitis. It is used only when nasal congestion is present and can be used with antihistamines. In the United States, oral decongestants containing pseudoephedrine must be purchased behind the pharmacy counter by law in effort to prevent the making of methamphetamine.

Intranasal corticosteroids are used to control symptoms associated with sneezing, rhinorrhea, itching, and nasal congestion. Steroid nasal sprays are effective and safe, and may be effective without oral antihistamines. They take several days to act and so must be taken continually for several weeks, as their therapeutic effect builds up with time.

In 2013, a study compared the efficacy of mometasone furoate nasal spray to betamethasone oral tablets for the treatment of people with seasonal allergic rhinitis and found that the two have virtually equivalent effects on nasal symptoms in people.

Systemic steroids such as prednisone tablets and intramuscular triamcinolone acetonide or glucocorticoid (such as betamethasone) injection are effective at reducing nasal inflammation, but their use is limited by their short duration of effect and the side-effects of prolonged steroid therapy.

A 2015 Cochrane systematic review assessing the prevention of chemotherapy-induced oral mucositis concluded that oral cryotherapy leads to large reductions in the incidence of oral mucositis of all severities in adults receiving 5-FU treatment for solid cancers. The evidence also indicates a reduction of oral mucositis in adults receiving high-dose melphalan-based cancer treatment prior to haematopoietic stem cell transplantation, although there is uncertainty regarding the size of the reduction in this instance. No evidence was found for use of this preventive measure in children. Oral cryotherapy involves the placement of rounded ice chips in the mouth, which cools the oral tissues and causes vasoconstriction. This decreases blood flow to the region and, hence, also restricts the amounts of the chemotherapy drugs delivered to the tissues.

It is extremely difficult to successfully treat BPF, mainly because of the difficulty obtaining a proper diagnosis. Since the disease starts out with what seems to be a common case of conjunctivitis, "H. aegyptius" is not susceptible to the antibiotic eye drops that are being used to treat it. This treatment is ineffective because it treats only the local ocular infection, whereas if it progresses to BPF, systemic antibiotic treatment is required. Although BPF is susceptible to many commonly used antibiotics, including ampicillin, cefuroxime, cefotaxime, rifampin, and chloramphenicol, by the time it is diagnosed the disease has progressed too much to be effectively treated. However, with the fast rate of progression of BPF it is unlikely that it will be successfully treated. With antibiotic therapy, the mortality rate of BPF is around 70%.

In very severe cases of necrotizing scleritis, eye surgery must be performed to repair damaged corneal tissue in the eye and preserve the patient's vision. For less severe cases, nonsteroidal anti-inflammatory drugs, such as ibuprofen, are prescribed for pain relief. Scleritis itself is treated with an oral medication containing corticosteroids and an eye solution. In some cases, antibiotics are prescribed. Simply using eye drops will not treat scleritis. In more aggressive cases of scleritis, chemotherapy (such as systemic immunosuppressive therapy with such drugs as cyclophosphamide or azathioprine) may be used to treat the disease. If not treated, scleritis can cause blindness.

The basic method for control of the conjunctivitis includes proper hygiene and care for the affected eye. If the conjunctivitis is found to be caused by "H. aegyptius" Biogroup III then prompt antibiotic treatment preferably with rifampin has been shown to prevent progression to BPF. If the infected person resides in Brazil, it is mandatory that the infection is reported to the health authority so that a proper investigation of the contacts can be completed. This investigation will help to determine the probable source of the infection.

Due to the different underlying causes, proper diagnosis, treatment, and prognosis can only be determined by an eye care professional. Punctate epithelial erosions may be treated with artificial tears. In some disorders, topical antibiotic is added to the treatment. Patients should discontinue contact lens wear until recovery.
