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...

Summary

This summary is machine-generated.

Corneal transplant (CT) waiting lists face challenges as older patients and longer waits decrease eagerness for surgery. Secondary health issues and anticoagulant use also hinder timely CT procedures.

Background:

Corneal transplantation is a common procedure to restore vision.
Waiting lists for corneal transplants can be dynamic and influenced by patient factors.
Understanding patient availability and willingness is crucial for efficient organ allocation.

Purpose of the Study:

To evaluate the dynamic nature of the corneal transplant waiting list.
To assess the willingness of corneal transplant candidates to undergo surgery.
To identify factors influencing patient availability and postponement of corneal transplant operations.

Main Methods:

Evaluated the response of 96 consecutive corneal transplant candidates to an operation call.
Assessed patient age, visual acuity, transplant indication, waiting period, and reasons for refusal.
Classified patients into available (Group 1) and unavailable (Group 2) groups.

Main Results:

96 patients were called to find 48 suitable candidates for corneal tissue transplantation.
Call refusal rates increased in patients over 70 years old.
Longer waiting times (over 22 months) and older age correlated with decreased willingness for surgery; secondary health problems and anticoagulant use were significant reasons for postponement.

Conclusions:

Patient age and prolonged waiting periods negatively impact the willingness for corneal transplantation.
Secondary health conditions and systemic anticoagulant use pose significant challenges to the corneal transplant waiting list's efficiency.
Strategies to address patient health and medication issues are needed to improve corneal transplant logistics.
