[Efficiency of laser trabeculotomy in open-angle glaucoma]

Area of Science:

• Ophthalmology
• Surgical Innovation
• Glaucoma Research

Background:

• Open-angle glaucoma (OAG) poses a significant challenge to vision preservation.
• Current OAG treatments aim to reduce intraocular pressure (IOP) and improve aqueous humor outflow.
• Minimally invasive glaucoma surgeries (MIGS) are increasingly explored for efficacy and safety.

Purpose of the Study:

• To evaluate the efficacy and safety of Neodymium-doped Yttrium Aluminum Garnet (Nd:YAG) laser trabeculotomy in patients with open-angle glaucoma.
• To assess the impact of Nd:YAG laser trabeculotomy on intraocular pressure and outflow facility.
• To report complications and visual acuity outcomes following the procedure.

Main Methods:

• Nd:YAG laser trabeculotomy was performed on 71 eyes across 48 patients diagnosed with open-angle glaucoma.
• Patient demographics included ages ranging from 15 to 86 years (mean 67 years).
• Follow-up duration ranged from 0.5 to 1.5 years.

Main Results:

• Successful normalization of intraocular pressure was achieved in 90% of treated eyes.
• Outflow facility demonstrated significant improvement in 87.3% of cases.
• A small percentage of eyes (2.8%) experienced deterioration in visual acuity, and 4.2% had anterior chamber hemorrhages.

Conclusions:

• Nd:YAG laser trabeculotomy presents a highly effective surgical option for managing open-angle glaucoma.
• The procedure demonstrates a favorable safety profile with substantial IOP-lowering and outflow enhancement capabilities.
• Further comparative studies are warranted to solidify its position among glaucoma surgical interventions.
