RETRACTION OF CYSTOID MACULAR EDEMA FROM THE FOVEA AFTER INTRAVITREAL ANTI-VASCULAR ENDOTHELIAL GROWTH FACTOR THERAPY...

To report the effect of anti-vascular endothelial growth factor inhibitor on fovea-involving cystoid macular edema in a patient with Birdshot chorioretinopathy.

A 42-year-old male patient presented to our hospital with bilateral posterior uveitis with retinal vasculitis, cystoid macular edema, and optic disk edema. He was diagnosed with birdshot chorioretinopathy based on clinical appearance and tissue type HLA-A29.

The patient underwent vitrectomy in the right eye without any change in visual acuity. Retinal leakage was reduced by oral prednisolone, which could not be tapered below 50 mg per day without relapse. Oral prednisolone, topical dexamethasone, and subtenon Kenalog were associated with intraocular pressure rise in both eyes. Hence, his uveitis responded to steroids, but there was no detectable effect of any steroid-sparing immunomodulatory drugs. The patient had been on oral prednisolone 50 mg for five years when it was decided to attempt intravitreal vascular endothelial growth factor inhibitor injection therapy. The anti-vascular endothelial growth factor therapy diminished cystoid macular edema in the fovea and improved the visual acuity.

Here, we report for the first time the long-term outcomes of anti-vascular endothelial growth factor injections on fovea-involving cystoid macular edema in Birdshot chorioretinopathy to keep steroid at the minimal possible doses and preserve a satisfying visual acuity level.
