Macular Atrophy Incidence, Progression, and Visual Acuity Effects in 5-Year Treatment of Neovascular Age-Related Macular Degeneration.

BACKGROUND AND OBJECTIVE: Macular atrophy (MA) contributes to declining vision during prolonged anti-vascular endothelial growth factor (VEGF) treatment in neovascular age-related macular degeneration (nAMD) so greater understanding of its incidence, evolution, and impact on visual acuity is merited. MATERIALS AND METHODS: This is a retrospective review of nAMD patients receiving anti-VEGF therapy for ≥ 5 years. Near-infrared reflectance images and vision data were extracted every 6 months. MA lesion areas were measured using ImageJ. RESULTS: Vision showed a mean decline of -1.2 letters/year. Eyes with MA showed a greater decrease of -1.6 letters/year compared to eyes without MA (-0.7 letters/year). Cumulative incidence of MA was 38% at 5 years. MA was significantly associated with declining vision, showing a -0.7 letter decrease for every 1 mm2 increase in lesion size. CONCLUSION: Over a 5-year course of nAMD treatment, MA affected most eyes, and MA progression was significantly associated with vision decline.

Bilateral optic disc pits in a pediatric patient with Cobb syndrome.

PURPOSE: To describe a patient with Cobb Syndrome, a rare congenital disorder characterized by cutaneous and spinal arteriovenous malformations, who was found to have bilateral optic nerve pits. OBSERVATIONS: A 15-year-old boy diagnosed with Cobb Syndrome, manifesting as a large cutaneous port-wine stain associated with an underlying left paraspinous arteriovenous malformation resulting in severe scoliosis, presented for a screening ophthalmological exam. The patient had no visual symptoms. On examination, his visual acuity was 20/20 in each eye; however, bilateral optic disc pits were discovered on biomicroscopy and confirmed by spectral-domain optical coherence tomography. CONCLUSION AND IMPORTANCE: The unusual finding of bilateral optic disc pits in this rare congenital neurocutaneous disorder represents the first report of ophthalmic abnormalities in association with Cobb syndrome. Patients with Cobb Syndrome may be considered for screening ophthalmological exam for the detection of subclinical optic nerve abnormalities.
