N2 - Purpose: To describe a case of retinal arterial macroaneurysm associated with macular pucker with good response to subthreshold laser treatment. Presentation: Two-year follow-up of a patient with decreased vision in one eye for the past 6 months. Baseline best-corrected visual acuity was 20/40 in the affected eye. Multiple retinal arterial macroaneurysms were diagnosed on biomicroscopy fundus examination, with the presence of subretinal fluid and hard exudates on macula. Multimodal imaging including optical coherence tomography and fluorescein angiography confirmed the diagnosis and presence of macular pucker, which complicated the treatment choice. The largest retinal arterial macroaneurysm was treated 2 days after the diagnosis by means of subthreshold micropulse laser using an infrared diode laser with 1400 mW power, 200 ms exposure and 10% duty cycle. Results: Five months after the treatment, despite absorption of subretinal fluid, there were increased hard exudates at the posterior pole and best-corrected visual acuity was unchanged. Progressively, the exudates were absorbed and vision improved. Eighteen months after the treatment, best-corrected visual acuity was 20/25. Hard exudates were almost completely reabsorbed, with no evidence of fluid. Macular pucker was unchanged, with no retinal traction or complications related to conventional laser treatment. Conclusion: Subthreshold laser treatment could be the treatment of choice in complicated cases of retinal arterial macroaneurysm with macular pucker, as it is able to modify the vessel permeability, without any thermal negative effect.
