Abstract
Purpose:
To observe recovery of photoreceptors in the macula of idiopathic choroidal neovascularization (ICNV) patients and to assess correlations between cone analyses and OCT images.
Methods:
Three eyes of 3 patients with ICNV were studied. All patient received intravitreal injections of 1.25mg bevacizumab (IVB). After subretinal fluid was resolved, adaptive optics (AO) images were obtained with rtx1TM (Imagine Eyes ,France) and cone analyses were performed. Changes in OCT and visual acuity were examined during the follow up.
Results:
After subretinal fluid was resolved by IVB, decimal visual acuity of all patients improved to 1.0. In AO images, cone photoreceptors were not observed in the area with absent or disrupted photoreceptor inner segment / outer segment (IS/OS) junction and cone outer segment tips (COST) line in OCT images. In the area with intact IS/OS junction and absent or disrupted COST line, cone photoreceptors returned to be observed after IVB. Cone density, cone spacing, and voronoi domains were improved with the recovery of the COST line in OCT.
Conclusions:
Recovery of cone photoreceptors in the macula of ICNV patients after IVB was associated with changes in OCT images.
