PURPOSE: To investigate the development and progression patterns of macular neovascularization (MNV)-related atrophies in eyes with pathologic myopia.
METHODS: Twenty-seven eyes of 26 patients with MNV followed from its onset to progression to macular atrophy were studied. A longitudinal series of autofluorescence and optical coherence tomography images were examined for the patterns of MNV-related atrophy. Changes in best-corrected visual acuity were determined for each pattern.
RESULTS: The mean age was 67.2 ± 8.7 years. The mean axial length was 29.6 ± 1.5 mm. Three patterns of atrophy were identified: multiple-atrophic pattern, 63% of the eyes had small atrophies occurring at multiple sites around the MNV edge; single-atrophic pattern, 18.5% had atrophies occurring only on one side of the MNV edge; and exudation-related pattern, 18.5% had atrophy occurring within a previous serous exudation or hemorrhagic area and slightly away from the MNV edge. Eyes with atrophies in multiple-atrophic and exudation-related patterns progressed to large macular atrophies involving the central fovea and showed decrease in best-corrected visual acuity during the 3-year follow-up period. Eyes with single-atrophic pattern had a sparing of the fovea and had good recovery of the best-corrected visual acuity.
CONCLUSION: There are three patterns of MNV-related atrophy in eyes with pathologic myopia with different courses of progression.
