Abstract

Purpose: To demonstrate the role of optical coherence tomography angiography (OCT-A) in the management of dome-shaped maculopathy (DSM). // Methods: Retrospective case review. // Results: A 52-year-old woman was referred to our retina service for potential bilateral choroidal neovascular membrane (CNVM) and blurry vision bilaterally. Initial spectacle-corrected visual acuity (VA) was 20/30-2 in the right eye (RE) and 20/30+2 in the left eye (LE). DSM was diagnosed on OCT. In both eyes, OCT B-scan passing through the fovea showed shallow, irregular RPE elevation (SIRE) suspicious of occult (type 1) CNVM. The outer retina and choriocapillaris angiograms showed a zone of nonexudative CNVM in the RE and exudative CNVM in the LE. Given the persistent SRF with CNVM in the LE, we elected to perform intravitreal injections of ranibizumab 0.5 mg on a treat and extend regimen. Upon the most recent follow-up, the best corrected VA improved to 20/20 in the LE with no persisting SRF. // Conclusion: We present a case where assessing disease progression, the development of CNVM and evaluating the efficiency of therapies were realized through the application of novel OCT-A technology. This diagnostic tool may be used to guide clinicians in their management of DSM, as demonstrated through our experience. OCT-A can also make it possible to visualize nonexudative CNVM lesions that may be missed on traditional imaging assessments.
