Cystoid macular edema, iritis, Herpes simplex keratitis, periocular skin darkening, and headaches have been described in patients treated with prostaglandin analogues. These adverse effects occur rarely, and cystoid macular edema, iritis and H. simplex keratitis occur in eyes with risk factors. Repeated rechallenge with masked controls is required to establish a causal relation. However, even without firm establishment of a causal relation, caution is advised with the use of prostaglandin analogues in the eyes of patients with risk factors for macular edema, iritis, and H. simplex keratitis (76).

Vidarabine [vye DARE a been] arabinofuranosyl adenine, ara-A, adenine arabinoside) is one of the most effective of the nucleoside analogs and is also the least toxic. However, it has been supplanted clinically by acyclovir, which is more efficacious and safe. Although vidarabine is active against herpes simplex virus type 1 (HSV-1), HSV-2, and varicella-zoster virus (VZV), its use is limited to treatment of immunocompromised patients with herpes simplex keratitis or encephalitis, or VZV infections. Vidarabine, an adenosine analog, is converted in the cell to its 5 -triphosphate analog (ara-ATP), which is postulated to inhibit viral DNA synthesis. Some resistant herpes virus...

There are many other causes of RCE, but they occur much less frequently. Among these causes are chemical or thermal burns, herpes simplex keratitis, neuroparalytic keratitis, bullous keratopathy, severe dry eyes, nocturnal lagophthalmos, diabetes mellitus, meibomian gland dysfunction, ocular rosacea, and Alport syndrome. Approximately 5% to 30% of RCEs occur spontaneously without any known predisposing fector. 

Herpes simplex keratitis (HSK) is caused by HSV type 1 in adults and is one of the most common infectious etiologies of blindness. It is second only to trauma as a cause of corneal blindness in the United States, where an estimated 50,000 new or recurrent cases are seen each year. Recurrent HSK can be reactivated by many factors in addition to those listed above. Reactivation has been reported in patients after penetrating keratoplasty, argon laser trabeculoplasty, Nd YAG laser peripheral iridotomy, or treatment with excimer lasers, including cases in which ocular herpes had not occurred previously. It is important to realize that because most patients have latent HSV it is possible for a reactivation to occur despite a negative history of a primary infection.
