OPTICAL COHERENCE TOMOGRAPHY ANGIOGRAPHY FINDINGS OF DEEP CAPILLARY PLEXUS MICROISCHEMIA AFTER INTRAVENOUS CHEMOTHERAPY FOR RETINOBLASTOMA.

Purpose: To study changes in the foveal microvascular anatomy using optical coherence tomography angiography (OCTA) after intravenous chemotherapy (IVC) for retinoblastoma (RB).

Methods: A retrospective comparative case-control series included 10 age-matched normal eyes with no documented ocular pathology (control), 10 fellow eyes of patients with unilateral RB treated with IVC (RB fellow), and 10 eyes with extramacular RB in patients with bilateral RB treated with IVC (RB tumor). All eyes were scanned using enhanced depth imaging optical coherence tomography and OCTA.

PARAFOVEAL MICROVASCULAR FEATURES ON OPTICAL COHERENCE TOMOGRAPHY ANGIOGRAPHY IN EYES WITH CIRCUMSCRIBED CHOROIDAL HEMANGIOMA.

Purpose: To evaluate parafoveal microvasculature in eyes with circumscribed choroidal hemangioma using optical coherence tomography angiography.

Methods: Fourteen eyes with unilateral circumscribed choroidal hemangioma were imaged using OCT for central macular thickness and optical coherence tomography angiography for superficial and deep foveal avascular zone area, and superficial and deep capillary density (CD), comparing affected and paired fellow eyes.

Results: Mean patient age was 53 years, and mean visual acuity was 20/60 in the involved eye and 20/25 in the fellow eye.
