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

Transconjunctival 20-gauge vitrectomy (T20V) is effective for short procedures like macular hole surgery. This novel technique shows a low complication rate, comparable to other sutureless vitrectomy systems.

Area of Science:

Ophthalmology
Surgical Techniques

Background:

Vitrectomy is a common surgical procedure for various retinal conditions.
Minimally invasive techniques aim to reduce surgical trauma and improve patient outcomes.

Purpose of the Study:

To evaluate the efficacy and safety of a novel transconjunctival 20-gauge vitrectomy (T20V) technique.
To assess T20V suitability for short-duration vitreous surgery.

Main Methods:

A prospective study included 12 eyes of 12 patients undergoing T20V.
Indications included macular hole, epiretinal membrane, vitreous hemorrhage, and central retinal vein occlusion neurotomy.
Procedures were designed for short-duration vitrectomy.

Main Results:

Average procedure time was 35 minutes.
Postoperative visual acuity improved significantly in most cases.
Intraocular pressure, pain, and foreign body sensation showed no statistically significant changes.
Minimal and transient chemosis was observed.

Conclusions:

Transconjunctival 20-gauge vitrectomy (T20V) is a viable option for short-duration vitrectomy.
The technique demonstrates a low incidence of ocular complications.
T20V outcomes are comparable to existing 23- and 25-gauge sutureless vitrectomy systems.
