BEVACIZUMAB FOR POST VITRECTOMY CYSTOID MACULAR EDEMA IN A SILICONE OIL-FILLED EYE

To report the safety and efficacy of intravitreal bevacizumab (IVB) in a case of cystoid macular edema (CME) in a silicone oil-filled eye.

A man, aged 51 years, reported with poor visual improvement in the right eye (RE) after pars plana vitrectomy with oil injection performed 2 months back for a pseudophakic, macula-off rhegmatogenous retinal detachment. His best-corrected visual acuity in the RE was counting fingers 2 m. Fundus examination of the RE showed a silicone oil-filled eye with attached retina, and CME was confirmed on spectral-domain optical coherence tomography. He was advised to undergo IVB injection, which was given a few days later.

One week after IVB, the central macular thickness had decreased to 437 μ m. Seven weeks later, the macular edema subsided completely with a final central macular thickness of 219 μ m. His vision improved by seven lines to 6/24 and was stable for another 2 months. He underwent removal of silicone oil after 3 months, wherein his visual acuity improved further by one line to 6/18.

This case demonstrates the use IVB for CME in a silicone oil-filled eye. It was found that IVB was safe and effective in CME associated with a silicone oil-filled eye.
