Purpose: To evaluate the effect of Bog Bilberry (Vaccinium uliginosum) extract in eyes with early age-related macular degeneration (AMD). Methods: Forty- four eyes of forty four patients with early AMD were included in this randomized, double-blinded, and placebo- controlled study. All participants were randomly assigned to either the placebo group (n = 24), or the bog bilberry extract group (n = 20). Before drug administration, an ophthalmic examination which included slit lamp microscopy, best corrected visual acuity, and intraocular pressure was performed, and repeated 1and 3 months after treatment. Objective scatter index, glare and tear film break-up time were checked by Optical Quality Analysis System (OQAS, Visiometrics, Spain) and drusen volume, central macular thickness, and RPE and IS/OS junction thickness were investigated with spectral-domain optical coherence tomography (Spectralis, Heidelberg, Germany). Results: In the bog bilberry extract group, RPE and IS/OS junction thickness was significantly increased compared to the placebo group after 3 months of drug administration. Conclusions: Bog Bilberry extract may play a favorable role in preventing the atrophic change of RPE and IS/OS junction layer and the progression of early macular degeneration.
