In many mild cases of conjunctivitis that have no infectious cause, the condition may clear up on its own. However, it’s unwise to delay veterinary treatment based on this fact, as the conjunctivitis may be a symptom of another, more serious condition.
The treatment method for conjunctivitis will depend on whether or not there is an underlying disease or infection causing it. Treatment usually takes anywhere from two to three weeks.
Infection
Antibiotics, whether administered by mouth or in eye drops, are generally effective for treating infectious causes of conjunctivitis. For herpesvirus, the vet may prescribe a topical medication, usually an ointment, in addition to antibiotics. There is no cure for the herpesvirus, and conjunctivitis caused by the virus is likely to come back; however, these treatments will help to manage symptoms when they appear.
Symptom of Disease
The recommended treatment course will vary depending on which disease is causing conjunctivitis. In many cases where the immune system is weak or suppressed as a result of the underlying disease, the vet will prescribe immune stimulants in addition to other treatments to manage symptoms.
Allergic Reaction
Conjunctivitis resulting from an allergic reaction will typically require topical treatments. Corticosteroid creams and drops are usually effective at reducing the symptoms of conjunctivitis. Your vet may prescribe additional medication to combat the reaction. It is very important that you use only corticosteroid creams prescribed by your vet as opposed to corticosteroid creams made for human use.
Non-Infectious Cases
For cases of conjunctivitis that have no identifiable cause, the vet may prescribe a general antibiotic medication in addition to anti-inflammatory drugs. These medications can be in capsule or topical form. In some severe cases, an injection may be required. Your vet will decide a course of treatment based on your cat’s specific needs.
