Abstract
BackgroundReport a rare case of retinal capillary macroaneurysm with associated subretinal fluid.Case presentationA 71-year-old male underwent full ophthalmic examination including Optical Coherence Tomography (OCT), Fluorescein Angiography (FA). Fundus examination showed moderate non-proliferative diabetic retinopathy of both eyes with scattered microaneurysms. On initial visit, FA displayed a hyperfluorescent lesion with leakage on late frames in the left eye. OCT revealed the lesion to be spheroid with a hyperreflective wall and hyporeflective lumen in the inner retina, corresponding to a capillary macroaneurysm. Intraretinal cystic fluid surrounded the lesion. On subsequent visit 7 months later, subretinal fluid in the location of the capillary macroaneurysm was noted on OCT. Vision was maintained at 20/30–2 OD, 20/40 OS throughout. No treatment was necessary.ConclusionSubretinal fluid from the capillary macroaneurysm likely developed from its juxtafoveal location and discontinuity of the external limiting membrane (ELM); a barrier preventing flow of intraretinal fluid to the outer retina.

Summary
Report a rare case of retinal capillary macroaneurysm with associated subretinal fluid.Case presentation: A 71-year-old male underwent full ophthalmic examination including Optical Coherence Tomography (OCT), Fluorescein Angiography (FA). Conclusion: Subretinal fluid from the capillary macroaneurysm likely developed from its juxtafoveal location and discontinuity of the external limiting membrane (ELM); a barrier preventing flow of intraretinal fluid to the outer retina. Known as microaneurysms, usually involve capillaries and are associated with ischemic conditions such as diabetes and retinal vein occlusions [3]. We report a unique case of a juxtafoveal capillary macroaneurysm associated with subretinal fluid.
