Summary
Acute primary angle-closure glaucoma (APACG) affects white women around age 59, presenting with worse visual acuity and shallower anterior chambers compared to their other eye. This study details APACG patient profiles and clinical differences.
Area of Science:
- Ophthalmology
- Glaucoma Research
- Clinical Ophthalmology
Context:
- Acute primary angle-closure glaucoma (APACG) is a significant cause of vision loss.
- Understanding the demographic and clinical profile of APACG patients is crucial for early diagnosis and management.
- Comparative analysis between affected eyes and contralateral eyes (CLEs) provides insights into disease-specific changes.
Purpose:
- To determine the demographic and clinical characteristics of patients diagnosed with acute primary angle-closure glaucoma (APACG).
- To compare clinical and morphometric parameters between eyes affected by APACG and their contralateral eyes (CLEs).
Summary:
- This prospective study evaluated 1343 patients, identifying 28 cases (2.1%) of APACG with an incidence of 20.8 per 1000 patients.
- APACG predominantly affected white women (average age 59.6 years) with no family history of glaucoma.
- Affected eyes showed statistically significant differences compared to CLEs, including worse visual acuity (uncorrected and corrected), higher cup/disc ratio, lower spherical equivalent, higher keratometry (K), and shallower anterior central chamber depth (ACCD).
Impact:
- The findings establish a clear demographic profile for APACG, aiding in risk identification.
- The comparative analysis highlights specific ocular parameters associated with APACG, potentially improving diagnostic accuracy.
- This research contributes to a better understanding of APACG pathophysiology and informs clinical management strategies.

Angle Closure Glaucoma: Treatment
Angle-closure glaucoma, or closed-angle glaucoma, is an eye condition where the iris bulges out and blocks the iridocorneal angle, resulting in a buildup of aqueous humor and increased intraocular pressure. Immediate medical attention is necessary due to the sudden onset of symptoms. The treatment for angle-closure glaucoma includes short-term and long-term approaches. Short-term treatment involves using eye drops like pilocarpine to lower intraocular pressure by increasing aqueous humor...
Glaucoma: Overview
Glaucoma is an eye condition characterized by increased intraocular pressure that damages the retina and optic nerve, leading to irreversible blindness if left untreated. The human eye has various components, including the cornea, iris, pupil, lens, and optic nerve. Aqueous humor is secreted by the epithelium of the ciliary body in the posterior chamber and flows through the trabecular meshwork and canal of Schlemm, maintaining normal intraocular pressure. The trabecular meshwork and the canal...
Open Angle Glaucoma: Treatment
In open-angle glaucoma, the iridocorneal angle remains open, but the trabecular meshwork becomes stiff, slowing down the outflow of aqueous humor. This causes a buildup of aqueous humor in the anterior chamber, leading to a sudden increase in intraocular pressure. The treatment for open-angle glaucoma focuses on reducing the elevated intraocular pressure by either decreasing the secretion of aqueous humor or increasing its outflow.
