Non-ischemic central retinal vein occlusion and paracentral acute middle maculopathy: Unveiling the central scotoma phenomenon.

Background: Central Retinal Vein Occlusion (CRVO) is a vascular disorder causing vision impairment, often associated with macular edema. Paracentral Acute Middle Maculopathy (PAMM) is a novel condition observed in CRVO cases, resulting in paracentral scotomas. We present a case of non-ischemic CRVO with PAMM.

Case Presentation: A 60-year-old male presented with an acute-onset central scotoma in the right eye. Examination revealed non-ischemic CRVO, and subsequent evaluation confirmed the presence of PAMM. Despite one-month follow-up, visual acuity and the scotoma did not improve. Imaging and functional tests supported the diagnosis of CRVO coexisting with PAMM. Low-dose aspirin was initiated.

Discussion: Non-ischemic CRVO can cause scotomas, including PAMM. PAMM manifests as hyperreflective lesions in the outer plexiform and inner nuclear layers, resulting from retinal ischemia. Early identification of PAMM is crucial for understanding vision loss in CRVO cases without macular edema. Visual field testing and microperimetry aid in diagnosis and monitoring.

Conclusion: PAMM should be considered in non-ischemic CRVO cases with vision loss. Integrating imaging and functional tests enhances accurate diagnosis and management of CRVO-associated complications, leading to improved outcomes.
