SPECKLED HYPOAUTOFLUORESCENCE AS A SIGN OF RESOLVED SUBRETINAL HEMORRHAGE IN NEOVASCULAR AGE-RELATED MACULAR DEGENERATION.

PURPOSE: To describe patterns of hypoautofluorescence in eyes with neovascular age-related macular degeneration occurring after subretinal hemorrhage.

METHODS

This was a retrospective descriptive analysis of neovascular age-related macular degeneration eyes presenting with subretinal hemorrhage over the last 5 years that underwent serial multimodal imaging. A review of color fundus photographs, fundus autofluorescence, near-infrared reflectance, and optical coherence tomography was performed at baseline and all available follow-up visits to document the course and evolution of subretinal hemorrhage in these eyes.

RESULTS

Eleven eyes of 10 patients (9 female, 1 male; mean age: 84.1 years, range: 72-99 years) with a mean follow-up of 19.8 months (range: 3-68 months) were included. Color fundus photographs showed subretinal hemorrhage that resolved over a mean of 5.5 months. During and after hemorrhage resolution, all eyes showed hypoautofluorescence, which appeared distinct from that due to retinal pigment epithelium loss. Discrete multifocal punctate hyperpigmented lesions were observed in 90% of eyes and were markedly hypoautofluorescent, producing a speckled pattern on fundus autofluorescence.

CONCLUSION

Areas of hypoautofluorescence in the absence of retinal pigment epithelium atrophy, often with a speckled pattern, delineate areas of prior subretinal hemorrhage long after its resolution in patients with neovascular age-related macular degeneration. Potential mechanisms for the development of this pattern are proposed.
