Further Outpatient Care
- The major difficulties in treating herpetic keratitis are related to the tendency for recurrences and to the management of stromal disease. In its latent form, HSV can be present in the cells of the cornea and in the central connections of the trigeminal nerve, particularly in the trigeminal ganglion. Disturbance of the nerve results in reactivation of the virus and its subsequent passage centrifugally along the nerve, with shedding from the nerve endings. Lesions tend to occur when the balance between latency and host defenses is disturbed, such as during febrile illnesses, during menses, or on exposure to sunlight. Once trigger factors are identified, they need to be avoided. Using 400 mg of acyclovir once or twice a day as prophylaxis can reduce the incidence of recurrence.[20, 21] This is recommended for patients with recurrent stromal disease or more than 2 episodes of epithelial disease per year.[22, 23]
Inpatient & Outpatient Medications
- Acyclovir (400 mg bid) as prophylaxis to prevent recurrence
Deterrence/Prevention
- Acyclovir (400 mg qd or bid) as prophylaxis to prevent recurrence
Complications
- Even with proper treatment, corneal scarring can occur, and, if it is central, visual acuity can be lost.
Prognosis
- The prognosis is generally favorable with aggressive treatment.
Patient Education
- Early recognition of symptoms is important for the treatment of recurrences.
