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...

Area of Science:

Ophthalmology
Corneal Surgery
Vision Science

Background:

Advanced keratoconus significantly impairs vision and corneal shape.
Intracorneal ring segments (INTACS) are used to regularize the cornea.
Evaluating INTACS in advanced keratoconus is crucial for treatment optimization.

Purpose of the Study:

To assess the surgical outcomes of microthin intracorneal ring segment (INTACS) implantation.
To evaluate the efficacy and safety of INTACS in patients with advanced keratoconus.

Main Methods:

INTACS implantation was performed in 14 eyes with advanced keratoconus.
Key outcome measures included visual acuity, refractive error (MRSE), and keratometry.
Data were analyzed at 6 months and 1 year post-implantation.

Main Results:

Significant improvements were observed in uncorrected and best spectacle-corrected visual acuity (P < 0.05).
Refractive error (spherical and cylindrical) and mean refractive spherical equivalent (MRSE) showed significant reduction (P < 0.05).
Average keratometry decreased, and results remained stable from 6 months to 1 year; the procedure was 100% safe.

Conclusions:

INTACS implantation offers significant visual and refractive benefits in advanced keratoconus.
The procedure is safe and effective, with no major complications or need for explantation.
INTACS represents a viable treatment option for managing advanced keratoconus.
