Summary
Glare disability significantly impacts mobility in glaucoma patients. This visual impairment affects walking speed, distance, and task load, particularly under dazzling conditions.
Area of Science:
- Ophthalmology
- Visual Science
- Rehabilitation
Background:
- Glare disability is a known issue affecting moderate to severe glaucoma patients.
- Reduced mobility performance under glare conditions poses challenges for glaucoma patients' daily lives.
Purpose of the Study:
- To evaluate glare disability in glaucoma patients.
- To assess the impact of glare on mobility and orientation in this population.
Main Methods:
- Twenty-two glaucoma patients and 12 controls underwent visual function tests and glare score (GS) measurements.
- Mobility was assessed on an artificial street (StreetLab) under photopic and mesopic+glare conditions, recording mobility time, distance, walking speed (WS), and Nasa task load index (Nasa-TLX).
Main Results:
- Glaucoma patients exhibited significantly higher glare scores compared to controls (P=0.001-0.049).
- Under mesopic+glare conditions, glaucoma patients showed significantly worse mobility performance (mobility time, distance, WS, Nasa-TLX) compared to controls (P=0.006-0.046).
Conclusions:
- Glare disability is present in moderate and severe glaucoma.
- This visual impairment significantly impacts the mobility performance of glaucoma patients.

01:27Open Angle Glaucoma: Treatment
758
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.

01:25Glaucoma: Overview
988
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...

01:28Angle Closure Glaucoma: Treatment
890
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...
