Case 8-47. Choroidal Neovascularization
A 50-year-old-man with a history of myopic degeneration had a visual acuity of 20/150 in his left eve associ-
a ted with sub fovea 1 choroidal neovascularization. Indirect ophthalmoscopy (A) demonstrated a pigmented lesion in the macula with hemorrhage along the superior border. A tilted optic disc with peripapillary atrophy and areas of chorioretinal atrophy along the nasal border was also noted. A lacy network of fluorescence consistent with a neovascular membrane was visible centrallv within the macula on fluorescein angiography (B), which also showed hvpofluorescence in the superior macula due to blockage by hemorrhage.
A well-defined region of enhanced optical reflecti\ i tv from the outer la vers of the retina was observed in the OC I image (C). The increased backscatter signal was contiguous with the reflection from the retinal pigment epithelium and chori oca pilla ris consistent with a the presence of a neovascular membrane.
