Summary
Early diagnosis of high myopia (HM) with primary open-angle glaucoma (POAG) is challenging. Specific fundus changes in HM can mask glaucoma, necessitating pupil dilation and stereo-photos for accurate detection.
Area of Science:
- Ophthalmology
- Glaucoma Research
- Myopia Studies
Context:
- Primary open-angle glaucoma (POAG) diagnosis is complicated by high myopia (HM).
- Understanding the interplay between HM and POAG is crucial for early detection.
- Existing diagnostic methods may be less effective in HM patients.
Purpose:
- To identify early diagnostic markers for high myopia combined with primary open-angle glaucoma.
- To compare visual field defects, retinal nerve fiber layer defects (RNFLD), intraocular pressure, and visual acuity in different myopia groups with POAG.
- To analyze clinical characteristics of HM-POAG using direct observation and stereo-photos.
Summary:
- Patients with HM and POAG exhibited more severe visual field defects and RNFLD, with lower corrected visual acuity compared to those with medium or low myopia.
- Fundus alterations in HM patients can impede the early detection of glaucoma.
- Pupil dilation and stereo-photography are key to improving glaucoma detection rates in HM patients.
Impact:
- Improved early detection rates for high myopia combined with primary open-angle glaucoma.
- Enhanced clinical proficiency in diagnosing HM-POAG.
- Better understanding of the diagnostic challenges posed by high myopia in glaucoma screening.
