Ophthalmological examinations were performed in all cases. Choroidal thicknesses (CTs) were measured under the fovea, 3 mm nasal to the fovea and 3 mm temporal to the fovea, and they were recorded as submacular (SCT), nasal (NCT) and temporal (TCT) choroidal thicknesses. CTs were measured and recorded by using EDI-OCT imaging (Cirrus HD 4000, Carl Zeis Meditec, CA, USA). Mesopic, scotopic and photopic pupil diameter sizes were measured and recorded by using Scheimpflug/Placido photography-based topography system in the pupillometer mode (Sirius, Italy). CTs, scotopic, mesopic and photopic pupil diameter sizes were measured and recorded at baseline, 1st and 3rd months.
