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...

Glaucoma: Overview

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

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

Immediately sequential bilateral angle surgery (ISBAS) reduces costs and anesthesia time in pediatric glaucoma patients. Single-incision ab interno trabeculotomy (SIT) significantly decreases anesthesia exposure, offering a cost-effective alternative.

Area of Science:

Ophthalmology
Pediatric Surgery
Health Economics

Background:

Pediatric glaucomas are sight-threatening conditions requiring surgery, often involving repeated general anesthesia.
Limited comparative data exists on operative costs and anesthesia exposure for pediatric glaucoma surgeries.
Evidence-based decision-making is hindered by a lack of comparative economic and time-based data.

Purpose of the Study:

To quantify and compare operative costs and operating room (OR) time for common pediatric glaucoma surgeries.
To specifically analyze unilateral angle surgery versus immediately sequential bilateral angle surgery (ISBAS).
To compare single-incision ab interno trabeculotomy (SIT) against other angle surgery techniques.

Main Methods:

Retrospective review of 160 pediatric glaucoma surgical encounters from January 2012 to August 2019.
Classification of surgeries by type, operative cost, and total OR time.
Analysis focused on ISBAS and SIT compared to conventional procedures.

Main Results:

ISBAS incurred costs of $11,391 and 120 min OR time, saving $2174 and trending toward 33 min less OR time compared to separate bilateral surgeries.
Single-incision ab interno trabeculotomy (SIT) was $1647 more expensive than conventional techniques but reduced OR time by 23.5 min.
SIT had comparable costs to 360-degree trabeculotomy ab externo but reduced OR time by 74.4 min; no difference in complications between unilateral and ISBAS.

Conclusions:

ISBAS demonstrates reduced costs and a trend toward reduced anesthesia time, supporting its use in pediatric glaucoma surgery.
SIT significantly decreases general anesthesia exposure for pediatric glaucoma patients, with neutral to slightly increased costs.
These findings support ISBAS and SIT as valuable options for managing pediatric glaucoma, balancing efficacy, cost, and anesthesia exposure.
