Journal Title: Guoji Yanke Zazhi - Year 2018, Vol 18, Issue 5
Abstract
AIM: To investigate the value of optical coherence tomography(OCT)in maculopathy of high myopia. <p>METHODS: Totally 50 patients(50 affected eyes)with high myopia who were admitted to our hospital during the period from June 2016 to May 2017 were prospectively enrolled in the observation group, and 50 normal healthy people(50 eyes)were selected as the control group at the same time. All subjects completed the conventional ophthalmic examination and OCT after admission. The visual acuity, intraocular pressure, diopter, eye axis, macular thickness and morphological changes were recorded, and detection of maculopathy of high myopia by different examination methods was statistically analyzed. <p>RESULTS: Conventional ophthalmic examination showed that the macular region was normal in 37 eyes and abnormal in 13 eyes(26%)while OCT showed that it was normal in 12 eyes and abnormal in 38 eyes(76%)in the observation group. The rate of maculopathy detected by OCT was higher than that by conventional ophthalmologic examination, with a significant difference(<i>P</i><0.05). The rates of subretinal or choroidal neovascularization and macular epiretinal membrane detected by OCT were higher than those by conventional ophthalmologic examination, with significant differences(<i>P</i><0.05). There was no significant difference in the proportion of normal results between conventional ophthalmologic examination and OCT in the control group(<i>P</i>>0.05). The intraocular pressure, diopter and axial length of patients with high myopia and maculopathy were higher/longer than those of the control group, the BVCA was worse than that of the control group, the thickness of retinal macular region, thickness of nerves above and below the optic disc, thickness of optic nerves on the bitamporal and nasal sides of the optic disc were lower than those of the control group, with significant differences(<i>P</i><0.05). <p>CONCLUSION: OCT can quantitatively determine the thickness of nerve fiber layer around the retina in patients with high myopia, and clearly display the characteristics of maculopathy, which can provide reliable quantitative data for the diagnosis of maculopathy of high myopia.
