Abstract

Purpose. Comparative analysis efficiency of diagnostic of myopic staphylomas using optical coherence tomography (OCT) with scan protocols different lengths. Material and methods. A 52-year-old patient with high axial myopia with myopic staphyloma was examined. Profound ophthalmological examination was carried out using OCT of the posterior pole of the eye using scans protocols of various lengths, ultrasound ocular echography. The presence and localization of scleral staphyloma was assessed. Results. When examining the posterior pole of the eye using 12 mm linear OCT scanning, no signs of staphyloma were detected in both eyes. Radial OCT scans 10 mm in length, 3D OCT scans size 12×9 mm scan made it possible to suspect the presence of large macular myopic staphyloma. Examination of patient using 16.5 mm linear OCT scanning revealed distinct prolapse of the posterior pole of the eye, capturing the optic disk and the macular area in both eyes. Ultrasound B-scan confirmed the presence of staphyloma of the posterior pole of the eye in both eyes. Conclusions. 1. To identify the presence and localization of myopic staphyloma, the most informative method is 16.5 mm OCT scanning. 2. For the diagnosis of myopic staphilomas, it is possible to use 12 mm OCT scanning. Key words: optical coherence tomography, myopia, myopic staphyloma, scleral staphyloma.
