RESUMO
PURPOSE: To describe and assess the prognostic significance of subretinal transient hyporeflectivity (STHR) on a novel spectral domain optical coherence tomography (SD-OCT) in age-related macular degeneration. METHODS: Consecutive patients with age-related macular degeneration (AMD) presenting STHR, defined as a small, well-defined, round subretinal, hyporeflective lesion, on SD-OCT and without exudative signs were included. Clinical examination and SD-OCT (SPECTRALIS, Heidelberg Engineering, Heidelberg, Germany) were analyzed at inclusion, 1 month before inclusion, and until the onset of exudative signs during the 12-month follow-up. RESULTS: Thirty-five STHR in 21 eyes of 20 patients were included. Among the 21 eyes, 2 eyes had early AMD, 1 eye had nonexudative asymptomatic macular neovascularization, and 18 eyes presented late AMD: 17 eyes neovascular AMD and 1 eye geographic atrophy. During the 2-month follow-up, 97.1% (34/35) of STHR disappeared. During the 12-month follow-up, 57.1% of eyes (12/21) developed exudative signs on 1 eye with early AMD and 11 eyes with neovascular AMD. CONCLUSION: Subretinal transient hyporeflectivity is a novel SD-OCT sign in patients with AMD. The eyes with isolated STHR should be closely monitored on a monthly basis to detect further exudation.
