Glaucoma is the leading cause of irreversible blindness in the world. Myopia is a risk factor for glaucoma. With the rising prevalence of both myopia and glaucoma in an ageing population, the occurrence of these two ocular conditions in the same patient is likely to increase. It was estimated that there were 163 million people who have high myopia in 2000, and the population with high myopia would increase to almost one billion (9.8% of the world population) worldwide by 2050.
There is often a diagnostic challenge to the clinician, since the detection of glaucomatous optic nerve damage in highly myopic eyes is difficult. Recently, the subclassification of peripapillary area could potentially be used to differentiate myopic eyes with and without glaucoma according to OCT findings.
However, the characteristics of peripapillary atrophy have not been fully applied in the diagnosis of high myopia and glaucoma.
In view of the above problems, the purpose of this study is to analyze the peripapillary area based on optical coherence tomography and it may be a specific marker for identifying high myopia with primary open angle glaucoma.
