Summary
Phaco-viscocanalostomy (VCS) offers superior intraocular pressure (IOP) control and fewer vision-threatening complications compared to phaco-trabeculotomy (LOT) in open-angle glaucoma patients. This study highlights VCS as a potentially safer and more effective surgical option for managing glaucoma.
Area of Science:
- Ophthalmology
- Glaucoma Surgery
- Surgical Outcomes
Background:
- Open-angle glaucoma requires effective surgical management to control intraocular pressure (IOP).
- Phaco-viscocanalostomy (VCS) and phaco-trabeculotomy (LOT) are surgical techniques used for glaucoma treatment.
- Comparative data on the long-term efficacy and safety of these procedures are crucial for clinical decision-making.
Purpose of the Study:
- To compare the surgical outcomes of phaco-viscocanalostomy (VCS) versus phaco-trabeculotomy (LOT) in patients with open-angle glaucoma.
- To evaluate intraocular pressure (IOP) reduction and the incidence of complications associated with each surgical technique.
Main Methods:
- A nonrandomized, retrospective clinical study involving 220 eyes (110 VCS group, 110 LOT group).
- Mean follow-up duration of approximately 2.35 years (857 days).
- Comparison of preoperative and postoperative IOP, medication usage, and complication rates.
Main Results:
- Phaco-viscocanalostomy (VCS) demonstrated significantly better IOP control at 1 and 3 years postoperatively compared to phaco-trabeculotomy (LOT).
- The VCS group required significantly fewer medications and had a lower probability of needing medications to maintain target IOP.
- VCS showed a significantly lower incidence of vision-threatening complications, including hyphema and IOP spikes, compared to LOT.
Conclusions:
- Phaco-viscocanalostomy provides superior intraocular pressure (IOP) control in open-angle glaucoma patients over a middle-term follow-up period.
- Phaco-viscocanalostomy is associated with a lower incidence of vision-threatening complications compared to phaco-trabeculotomy.
- VCS emerges as a potentially more effective and safer surgical option for managing open-angle glaucoma.

01:28Angle 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...
01:27Open 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.

01:25Glaucoma: 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...
