Abstract Details


To compare the clinical and morphological findings of pachychoroid neovasculopathy and to interpret its specific features in patients who presented pachychoroid features and flat irregular pigment epithelial detachment.


Ankara University Faculty of Medicine Department of Ophthalmology


Nineteen eyes of 17 patients presenting with flat PED and pachychoroid features with no features of age-related macular degeneration (AMD) or any other degenerative changes were analysed. Fundus fluorescein angiography (FFA) and/or an indocyanine green angiography (ICGA) and optical coherence tomography angiography (OCT) were performed at the same visit. Subfoveal choroidal thickness was measured on EDI mode of the SD-OCT.


Mean age was 59.1 years. Mean subfoveal choroidal thickness was 388μm. ICGA revealed existence of choroidal vascular plaque in 8 (44.4%), a conspicious plaque in 5 (27.8%) of the eyes, and it showed non-neovascular features such as hyperpermeability or dilated choroidal vessels in 5 (27.8%) of the eyes. OCT-A depicted presence of choroidal neovascularisation in 13 (72%) of the eyes and polypoidal structures in 1(5.3%) of the eyes. For all of the eyes which ICGA was positive for presence of choroidal neovascularization (CNV), OCT-A also showed CNV. OCT-A was also able to detect CNV in all of the eyes with conspicuous plaque, and in one eye with no neovascularisation on ICGA.


: In cases with pachychoroid spectrum diseases, OCT-A findings seems to be more sensitive for precise detecting type 1 choroidal neovascularization as compared to conventional dye angiography
