Comparion of Optic Dik and Retinal Nerve Fiber Layer Thickne in Nonglaucomatou and Glaucomatou Patient With High Myopia

Purpoe To ae the optic nerve head (ONH) by optical coherence tomography (OCT), confocal canning laer ophthalmocopy (CLO), and the retinal nerve fiber layer (RNFL) by OCT and canning laer polarimetry (GDx) in highly myopic ubject. Deign Obervational cro-ectional tudy. Method Thirty-five eye of highly myopic individual without glaucoma and 17 eye of highly myopic patient with glaucoma were included in thi tudy. All patient had myopia higher than 5.0 diopter and ocular axial length higher than 25 mm. In thoe patient without glaucoma, the intraocular preure (IOP) wa le than 21 mm Hg. Reult Mean (D) OCT cup-to-dik area ratio wa 0.45 (0.30) and 0.58 (0.29) in the nonglaucomatou and glaucomatou ubject, repectively (P = .22); CLO cup-to-dik area ratio wa 0.27 (0.27) and 0.24 (0.23), repectively (P = .75); and OCT-RNFL wa 65.2 (26.2) μm and 56.8 (28.6) μm (P = .43). Concluion OCT, CLO, and GDx are not ueful to dicriminate nonglaucomatou and glaucomatou ubject that have high myopia.
