Neurosensory retina detachment combined with retinal pigment epithelium separation from the choroid in the course of dry macular degeneration - A case report.

ABSTRACT

of advanced diagnostic methods shed the light on the variable course of age-related macular degeneration (AMD). Despite establishing AMD classifications used in clinical practice, there are still forms of AMD that do not fit into these systems. The case report presents a rare evolution of non-neovascular form of AMD presenting at baseline as large soft drusen. Within the 5 years of observation one eye with such form of AMD transformed to retinal pigment epithelial detachment and subsequently simultaneous separation of the neurosensory retina and the choroid from the RPE. As a result, on the spectral domain optical coherence tomography scan, the case presented with lone line of the RPE neighbored by subretinal fluid from the inner side and choroidal excavation from the outside. Macular neovascularization was excluded at each timepoint of the follow-up. During 2.5 years of observation post the onset of RPE separation, the case remained stable with maintained visual acuity at 0.25 Snellen and lack of progression to wet form of AMD. Further observation is needed to fully assess the eye's potential for visual preservation in the long term.
