OUTER RETINAL ATROPHY ON SPECTRAL DOMAIN OPTICAL COHERENCE TOMOGRAPHY AFTER RESOLUTION OF GLAUCOMA SURGERY-ASSOCIATED HYPOTONY MACULOPATHY.

PURPOSE: To report two cases of persistent central vision loss after resolution of filtration surgery-associated hypotony, corresponding with foveal outer retinal atrophy on spectral domain optical coherence tomography.

METHODS

Retrospective observational case series. A retrospective chart review was conducted of two patients with persistent vision loss after normalization of intraocular pressure and resolution of glaucoma surgery-associated hypotony maculopathy.

RESULTS

Several months after glaucoma surgery and resolution of hypotony, both patients suffered persistent vision loss and new foveal photoreceptor loss on spectral domain optical coherence tomography.

CONCLUSION

This is the first case series demonstrating foveal outer retinal atrophy on spectral domain optical coherence tomography after resolution of glaucoma surgery-associated hypotony maculopathy. Both patients had previous uveitis that was controlled at the time of hypotony. Eyes with previous hypotony and compromised ciliary body function may be at greater risk of photoreceptor damage.
