Favorable long-term prognosis of cataract surgery in herpes zoster ophthalmicus

Scleritis is a rare presentation of herpes zoster ophthalmicus, complicated most commonly by iridocyclitis and raised intraocular pressure. These complications can recur in subsequent years, therefore they should be managed well.
Case Report: We describe a female patient who developed scleritis, complicated cataract and secondary glaucoma 2 years after being diagnosed by HZO. Secondary glaucoma was managed medically, and the patient underwent extracapsular cataract extraction for the complicated cataract. Final visual acuity was 6/6 and IOP was 22.4 mm Hg. This is a rare report describing favorable long‑term (>20 years) prognosis for surgical management of cataract associated with HZO together with scleritis, secondary glaucoma and post‑herpetic neuralgia.
A favorable outcome may be attained with surgery for complicated cataract associated with HZO if the condition is managed optimally and intraocular inflammation is well controlled.
