Abstract

Objectives The aim was to evaluate the importance of choroidal changes as measured by enhanced depth imaging optical coherence tomography (OCT) in patient with myopic choroidal neovascularization (mCNV) and to assess the correlation between choroidal thickness (CT) and other parameters such as age, sex, refraction, and staphyloma. Background High myopia is associated with profound changes in the choroid, which are important in the pathogenesis of many important visually significant abnormalities such as choroidal atrophy, CNV, and lattice degeneration. Therefore, it is called pathologic myopia. Patients and methods This prospective study was conducted from June 2016 to January 2017. Two groups of eyes were included: mCNV eyes (31 eyes) and eyes without CNV (19 eyes). CT was measured using the spectralis spectral domain OCT (specralis software version 4.0) in the Ophthalmology Department of the Menoufia University Hospital. Results It was found that CT was significantly decreased in the mCNV eyes compared with normal eyes, as the mean subfoveal CT in eyes with CNV was 103.10 ± 41.09. The mean subfoveal CT in eyes without CNV was 193.28 ± 17.38 (P < 0.001). Conclusion The ability of enhanced depth imaging OCT to visualize the ocular structure provides a more in-depth understanding of the various ocular pathologies. We found that in patients, CT decreased with the presence of mCNV, as compared with controls.
