  • Abstract
  • Look Inside

We reviewed a series of 161 eyes with senile disciform macular degeneration (SDMD) regarding the angiographic findings of subretinal neovas-cularization (SRN) and ophthalmoscopic findings. We paid particular attention to the size, location and the stage of SRNs as related to pontential photocoagulation.

Out of the whole series, 60 eyes (37%) were assigned to the early stage, 79 (49%) to typical active stage and 22 (14%) to the cicatricial stage.Out of a total of 166 SRNs, 137 (83%) were located within one disc diameter from center of the fovea. The SRNs were smaller than 0.5 disc diameter in 71 eyes (43%). In eyes with typical active stage, 35 of 88 SRNs (40%) were located within the foveal avascular zone (FAZ). In eyes with early stage of the lesion, 21 of 73 SRNs (29%) were located within the FAZ.

The finding seemed to imply that an utmost effort is to be paid in early detection of SDMD and to develop a therapeutic modality to treat SRNs located within the FAZ.
