| Abstract|| |
We report a case of a young male with symptomatic isolated venous macro-aneurysm without any associated systemic disease. Multi modal imaging was useful in making the correct diagnosis. To the best of our knowledge, primary isolated venous macro-aneurysm has not been reported previously.
Keywords: Multimodal imaging, retina and intraretinal edema, venous macroaneurysm

Macroaneurysm (MA) can be classified into four categories: arterial, capillary, collateral associated, and venous. Venous MAs are further divided into secondary MAs, associated with disease and isolated MAs. Unlike arterial retinal MAs, there is insufficient data about retinal venous MAs. In literature, only three cases of isolated retinal venous MA have been published to date.,, In all three cases, there were associated conditions. Here, we report the fourth case of isolated venous MA; however, unlike the other three cases, the patient in our case was completely fit and healthy except the blurred vision.
A 45-year-old Asian nonsmoker man with no known comorbids presented with a complaint of gradual blurring of vision in the left eye for the past 6 months. He had no ocular or systemic history, particularly no hypertension. Fundus examination of the left eye showed a circinate arrangement of exudates juxtafoveally [Figure 1]a. Similarly, optical coherence tomography showed hyper-reflective exudates in the middle retinal layers surrounded by hyporeflective intraretinal edema [Figure 1]b and subfoveal localized neurosensory retinal detachment (not shown). A circular lesion with hyper-reflective border was noted in the middle retinal layers (white arrow). This represented saccular dilation of vasculature in the retina. The photoreceptor layer was intact. Fundus fluorescein angiography showed a normal choroidal and arterial phase in the left eye. Venous phase showed pinpoint leakage of the dye at the branching of second-order vein. There was leakage from venous MA, which led to intraretinal edema [Figure 1]c and [Figure 1]d. Of note was the surrounding normal vasculature, ruling out previous vascular occlusion. Examination of the right eye was unremarkable.
