Abstract：Objective To summarize the clinical features of primary open-angle glaucoma complicated with high myopia and to analyze the causes of misdiagnosis and treatment of this disease. Methods From June 2015 to Feb-ruary 2016,21 patients with high myopia complicated with primary open-angle glaucoma treated in Baoji People's Hos-pital were selected as the subjects of the study. Of them,6 patients were misdiagnosed,the clinical data of whom were analyzed retrospectively. Results The misdiagnosis rate was 28.57%. Of 6 patients,2 presented with orbital pain and blurred vision at 5 and 10 days after treatment respectively;2 presented with immediate shadow,foreign-body sensa-tion,and visual fatigue at 10 and 15 days after treatment;2 patients with blurred vision,dizziness,nausea and amauro-sis at 3 days after treatment. For them,high myopia with primary open-angle glaucoma was misdiagnosed as asthenopia in 2 cases,chronic conjunctivitis in 2 cases and migraine in 2 cases. The duration of misdiagnosis was 3-10 d. All the patients were treated accordingly but had no improvement. Continuous measurement of intraocular pressure, chamber angle,fundus and visual field confirmed high myopia with primary open-angle glaucoma. Subsequently,simple trabe-culectomy and composite trabeculectomy were performed in 5 and 1 patients respectively. After 6-15 d treatment as de-scribed above,all the patients were discharged home after the condition was significantly improved. They were followed up for periods ranging from 3 months to 1 year,and the prognosis was favorable. Conclusion Given aspecific and sub-tle clinical manifestations,high myopia with primary open-angle glaucoma is likely to be misdiagnosed. Therefore,cli-nicians should enhance the understanding of this disease,to reduce or avoid the misdiagnosis.
