330 trabeculectomies--a follow-up study through 1/2-3 years

Area of Science:

• Ophthalmology
• Microsurgery

Background:

• Glaucoma is a leading cause of irreversible blindness.
• Trabeculectomy, a microsurgical glaucoma procedure, was introduced in 1967.
• This technique is noted for minimal early complications and effective pressure reduction.

Purpose of the Study:

• To evaluate the efficacy and safety of trabeculectomy.
• To assess outcomes including intraocular pressure (IOP), visual acuity, and visual fields.
• To analyze surgical complications, re-operation rates, and the need for postoperative medical therapy.

Main Methods:

• A consecutive series of 330 trabeculectomy procedures were performed.
• Patient outcomes were monitored over a follow-up period of 0.5 to 3 years.
• Key metrics evaluated included IOP, visual acuity, visual fields, and complications.

Main Results:

• Trabeculectomy demonstrated a significant pressure-reducing effect in glaucoma patients.
• The procedure was associated with few early surgical complications.
• A low rate of re-operation and need for medical therapy was observed.

Conclusions:

• Trabeculectomy is a safe and efficient surgical intervention for glaucoma management.
• The procedure offers a viable alternative to intensive medical treatment for glaucoma.
• This microsurgical approach provides a favorable risk-benefit profile for patients.
