| Popis: | PURPOSE: To investigate choroidal vascular index (CVI) in eyes with nanophthalmos (NO) with the use of optical coherence tomography (OCT). METHODS: Macular enhanced depth imaging OCT scans of 25 eyes of 25 patients with NO and age–gender-matched 25 eyes of 25 control subjects were analysed. Images were binarized using the ImageJ software, and total choroid area (TCA), luminal area (LA) and stromal area (SA) were acquired. The main outcome measure was CVI, defined as the ratio of LA to TCA. RESULTS: Twenty-five eyes of 25 patients with NO and age–gender-matched control subjects were enrolled. The mean TCA, SA and LA were found to be significantly higher in patients with NO (2.51 ± 0.44 vs. 1.91 ± 0.35 mm(2), P |
