Description of clinical features of myopic patients with primary open-angle glaucoma
Nội dung chính của bài viết
Tóm tắt
This cross-sectional study analyzed 100 eyes from 50 myopic patients diagnosed with primary open-angle glaucoma (POAG) at Hanoi Opthalmology Hospital (2024 – 2025) to describe their clinical characteristics and evaluate the association between myopia severity and glaucomatous damage. Comprehensive eye examinations included refraction, intraocular pressure (IOP), visual field testing, and optical coherence tomography (OCT). Patients were grouped based on the degree of myopia. Results showed that average retinal nerve fiber layer (RNFL) thickness declined significantly with increasing myopia (p < 0.001), with a moderate inverse correlation (r = -0.48). Visual field loss, indicated by mean deviation (MD), was more severe in patients with high myopia (p = 0.002), despite most having normal IOP. Common optic disc features included tilted discs (60%) and peripapillary atrophy (82%), which often interfered with OCT interpretation in highly myopic eyes. These structural and functional alterations underscore the challenges in diagnosing glaucoma in myopic patients. Interpreting imaging and functional results considering myopia severity may improve diagnostic accuracy and facilitate timely intervention.
