Abstract

PURPOSE:

To describe the efficacy of laser and intravitreal injection of anti-vascular endothelial growth factor (anti-VEGF) agents for patients with symptomatic retinal arterial macroaneurysm (RAM).

DESIGN:

From 2009 to 2016, we collected patients with exudative or hemorrhagic RAM all treated by focal laser photocoagulation.

METHODS:

Nd:YAG laser was performed in patients with subinternal limiting membrane (sub-ILM) hemorrhage. Intravitreal anti-VEGF agents were given in eyes with macular exudation as adjuncts. Changes of visual acuity and central foveal thickness before and after treatment were recorded and compared with Wilcoxon signed-rank test.

RESULTS:

Thirty-five eyes that underwent a single session of laser photocoagulation for RAM resulted in macroaneurysm regression. The hemorrhagic group included 24 eyes having ruptured macroaneurysms without macular exudation. Five eyes with simultaneous sub-ILM hemorrhage receiving Nd:YAG laser membranotomy had resolution of preretinal hemorrhage. Exudative RAM having cystoid macular edema or submacular fluid with or without ruptured macroaneurysms was treated by focal laser photocoagulation alone in 3, or combined with single intravitreal anti-VEGF agent in 8 eyes. All patients had significantly improved vision when comparing visual acuity at baseline and final follow-up (P = 0.00016). Significant reduction of macular thickness was also observed after laser monotherapy or combined treatment in exudative RAM (P = 0.018).

CONCLUSIONS:

Focal laser photocoagulation was helpful for the management of ruptured or leaky RAM. Combined focal laser and intravitreal anti-VEGF agents could better reduce macular exudation caused by RAM. Additionally, Nd:YAG laser was a safe and effective method to remove the sub-ILM hemorrhage caused by RAM.
