PURPOSE: To describe a case of macular intraretinal microvascular abnormality (IRMA) detected with Optical Coherence Tomography Angiography (OCTA) and to show its remodeling and vascular density changes after panretinal photocoagulation (PRP) during an 18-month follow-up.
METHODS: Case report.
RESULTS: A 22-year-old female patient with proliferative diabetic retinopathy was found to have a small hyperreflective formation with posterior shadow cone and signal flow, located at the temporal margin of the fovea avascular zone (FAZ), identified as macular IRMA with OCTA. Her best-corrected-visual acuity was 20/20. Four months later the macular IRMA was larger and, in its context, there was also an increase in the flow area in B-scan. The patient underwent PRP and after 18 months we observed a regression of macular IRMA and an increase in the superficial capillary plexus vessel density in all sectors in comparison to baseline.
CONCLUSION: OCTA is a non-invasive tool that recognize macular IRMA in diabetic retinopathy patient and it could be helpful to follow their qualitative and quantitative vascular evolution over time.
