To determine optical coherence tomography signs associated with macular atrophy (MA) in eyes with neovascular age-related macular degeneration and pigment epithelial detachments treated with vascular endothelial growth factor inhibitors.
Optical coherence tomography scans from a subgroup of the pigment epithelial detachment cohort of the HARBOR study were analyzed for MA. Two groups were formed based on MA presence/absence at Month 24. Then, optical coherence tomography scans from each baseline visit were graded with standard reading center grading parameters including ellipsoid zone disruption, intraretinal cysts, subretinal fluid, and MA or nascent MA in the study and fellow eyes.
Twenty-eight eyes from 28 patients were included in the analysis. Fourteen eyes had optical coherence tomography–based MA at Month 24 and 14 did not. Macular atrophy at Month 24 was significantly associated with 1) MA/nascent MA at baseline (P = 0.0136), 2) intraretinal cysts at baseline (P = 0.0048), and 3) collapse of pigment epithelial detachments in the study eye (P = 0.0025). Macular atrophy was not associated with ellipsoid zone disruption or subretinal fluid in the study eye at baseline.
This study suggests that some optical coherence tomography findings in eyes of patients with neovascular age-related macular degeneration were present before the start of anti–vascular endothelial growth factor therapy and may predict the development of MA.
Optical coherence tomography allows for the visualization of signs that may be predictive of macular atrophy in eyes with neovascular age-related macular degeneration treated with vascular endothelial growth factor inhibitors.
