Exudative vascular anomalous complex-like lesion of the peripapillary area

Purpose Perifoveal exudative vascular anomalous complex is an uncommon retinal lesion of idiopathic origin characteristically described as an isolated, aneurysmal lesion of the perifoveal region. We report an unusual presentation of an exudative vascular anomalous complex-like lesion affecting the peripapillary area. Case description A 69-year-old diabetic woman presented with blurred vision in her left eye for two months. Fundus examination of the left eye showed a small, reddish-orange lesion just supratemporal to the optic disc with perifoveal hard exudates and retinal thickening. Fundus fluorescein angiography demonstrated a peripapillary hyperfluorescent lesion with minimal leakage. Ocular coherence tomography showed an oval structure extending throughout the outer and inner plexiform and nuclear layers with a hyper-reflective wall accompanied by subfoveal and intraretinal fluid suggestive of an eVAC-like lesion in the peripapillary area. Intravitreal anti-vascular endothelial growth factor injection was given, and the lesion persisted even three weeks after the injection. Later, focal laser photocoagulation of the aneurysmal lesion was done. At 6 weeks follow-up, a complete resolution of the aneurysmal lesion with a marked decrease in retinal edema and an improvement of the visual acuity was observed. Conclusion Exudative intraretinal aneurysmal lesions can occur in areas other than perifoveal area. OCT is an useful investigation for knowing their characteristics and the response to treatment. These aneurysmal lesions irrespective of their location can be called by the name eVAC-like or more aptly retinal capillary macro aneurysms (RCM).
