Treatment Of Recurrent Juxtafoveal Subretinal Neovascular Membranes with Krypton Red Laser Photocoagulation

Thirty-seven eyes initially treated with argon blue-green, argon green, or krypton red laser photocoagulation demonstrated a recurrent subretinal neovascular membrane (SRNVM) at the edge of the treatment scar extending into the foveal avascular zone and were retreated with krypton red laser photocoagulation. The subretinal neovascular membrane was due to the presumed ocular histoplasmosis syndrome (POHS) in 10 eyes, aging macular choroidal degeneration (AMCD) in 22 eyes, and miscellaneous causes in five eyes. Anatomic success, defined as complete obliteration of the recurrent SRNVM, was achieved in 26 eyes (70%). When compared to pretreatment visual acuities, 23 of 37 eyes (62.2%) had stable or improved postoperative visual acuities during the follow-up period. Twenty-six eyes were retreated one time; nine eyes required two retreatments; and two eyes required three retreatments. Final visual results showed visual acuity ≥20/40 in 7 eyes (18.9%); visual acuity ≥20/80 in 16 eyes (43.8%); visual acuity ≥20/100 in 19 eyes (51.4%); visual acuity ≥20/200 in 27 eyes (73%); and visual acuity ≥20/400 in 34 eyes (91.9%).
