Optical Coherence Tomography Angiography (OCTA) Findings in Retinitis Pigmentosa

Optical coherence tomography angiography (OCTA) is a noninvasive new imaging modality that can be used to diagnose and monitor progression of retinitis pigmentosa (RP). Cohorts and case series have shown correlation between OCTA findings and visual function and disease severity. Although an early use of the technology is promising, there are concerns about segmentation errors and artifacts. There is also a paucity of data on genotype and how that correlates with OCTA findings. Despite its limitations, OCTA remains a useful tool for clinicians managing retinitis pigmentosa patients.
