Materials and Methods: Thirty eyes of 30 patients diagnosed with pachychoroid spectrum disease and 30 age-gender matched healthy controls, were retrospectively included in the study. The results of the ophthalmological examination and the OCTA measurements of the participants were analyzed retrospectively.
Results: Subretinal fluid was found in all 20 eyes with Central Serous Chorioretinopathy, pigment epithelial detachment (PED) was found in 12 eyes (60%) and choroidal neovascularization (CNV) was found in 3 eyes (15%). The Pachychoroid Pigment Epitheliopathy patients had retinal pigment epithelium changes. Polypoidal multi-lobular PED and subretinal fluid were detected in all cases of Polypoidal Choroidal Vasculopathy and CNV was detected in 3 (50%) cases of PCV. Flat irregular PED and CNV were found in all Pachychoroid Neovasculopathy cases. The subfoveal choroidal thickness of the pachychoroid spectrum group was significantly higher than that of the healthy control group (p?0.05). The choriocapillaris flow values in the pachychoroid spectrum disease group were significantly lower than in the healthy control group (p?0.05).
Conclusions: OCTA is a noninvasive imaging modality very helpful in the diagnosis and differential diagnosis of pachychoroid spectrum disease.
