Angle Closure Glaucoma: Treatment

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...

Open Angle Glaucoma: Treatment

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.
Drugs such as carbonic anhydrase inhibitors, α2- and...

Background:

Amblyopia, or "lazy eye," affects visual development in children.
Traditional amblyopia treatments can face challenges with patient compliance.

Purpose of the Study:

To assess the efficacy of liquid crystal glasses (LCG) for treating amblyopia.
To evaluate patient compliance and acceptance of LCG treatment.

Main Methods:

A prospective interventional case series involving 24 children (aged 4-7.8 years) with monocular amblyopia.
LCG were used to provide electronically controlled occlusion to the non-amblyopic eye for 5 hours daily over 9 months.
Visual acuity (distance and near), fixation patterns, and binocular function were assessed regularly.

Main Results:

Significant improvement in mean distance visual acuity (0.27 to 0.59, P < 0.001).
Increased stereopsis, with 21% achieving good stereopsis (better than 60 sec arc) compared to 8% initially.
High compliance rate (92%) with LCG wear (≥8 hours/day).

Conclusions:

Liquid crystal glasses are an effective treatment for pediatric amblyopia, enhancing visual acuity and stereopsis.
The LCG treatment demonstrated good acceptance and compliance among children and their parents.
No serious adverse events were reported, suggesting a favorable safety profile.
