Case of lens-induced uveitis associated with supernormal flicker ERG amplitudes after cataract surgery.

Abstract

PURPOSE:

To report our findings in a case of lens fragment-induced uveitis associated with supernormal flicker electroretinograms (ERGs) twenty months after the cataract surgery.

METHODS:

This is an observational case report. Full-field flicker ERGs were recorded with the RETeval system. Optical coherence tomography (OCT) and slit-lamp biomicroscopy were used to assess the uveitis during the follow-up period.

RESULTS:

A 70-year-old man, who had undergone cataract surgery 20 months earlier, visited our hospital with a complaint of decreased vision in his right eye. Slit-lamp biomicroscopy revealed corneal edema and a lens fragment was detected in the inferior part of the anterior chamber. OCT showed cystoid macular edema, and flicker ERGs showed a marked increase in the amplitude and a delay in the implicit time in the right eye. These abnormalities of the flicker ERGs improved gradually after the removal of lens fragment and application of topical anti-inflammatory medications.

CONCLUSION:

Our case of lens-induced uveitis had supernormal flicker ERG amplitudes. Clinicians should be aware that eyes with uveitis can have larger-than-normal ERG amplitudes.
