'Microincisional trabeculectomy for glaucoma"

Area of Science:

• Ophthalmology
• Glaucoma Surgery
• Minimally Invasive Procedures

Background:

• Open-angle glaucoma (OAG) management often requires surgical intervention to control intraocular pressure (IOP).
• Traditional trabeculectomy can be associated with significant complications.
• Microincisional trabeculectomy (MIT) offers a less invasive surgical approach.

Purpose of the Study:

• To evaluate the short-term clinical outcomes of microincisional trabeculectomy (MIT).
• To assess the efficacy of MIT as an ab-interno trabeculectomy technique.
• To analyze IOP reduction and medication requirements post-MIT.

Main Methods:

• A prospective study included 32 eyes of patients with OAG undergoing MIT between September 2021 and June 2022.
• MIT was performed ab-interno using microscissors and microforceps.
• Outcomes measured included IOP reduction, medication use, surgical success rates, and complications at 6 months.

Main Results:

• All 32 eyes achieved >30% IOP reduction, with a mean final IOP of 14±6.9 mm Hg at 6 months.
• Surgical success was observed in 31 of 32 eyes, with 28 achieving complete success (no more than one medication).
• Complications were limited to transient hyphema and IOP spikes, with no additional interventions required for most cases.

Conclusions:

• Microincisional trabeculectomy (MIT) is an effective ab-interno technique for short-term IOP control in OAG.
• MIT demonstrates a favorable safety profile with fewer complications compared to traditional methods.
• Further long-term studies are needed to compare MIT with other glaucoma surgical procedures.
