Summary
Phacotrabeculectomy (PT) and trabeculectomy alone (TA) showed similar intraocular pressure control one year post-surgery. Adding phacoemulsification to trabeculectomy did not significantly impact glaucoma outcomes.
Area of Science:
- Ophthalmology
- Glaucoma Surgery
- Surgical Outcomes
Background:
- Glaucoma management often requires surgical intervention to lower intraocular pressure (IOP).
- Trabeculectomy is a common surgical procedure for glaucoma, but its efficacy can be enhanced with combined procedures.
Purpose of the Study:
- To compare the effectiveness of phacotrabeculectomy (PT) versus trabeculectomy alone (TA) in managing glaucoma.
- To evaluate the impact of combined phacoemulsification and trabeculectomy on intraocular pressure and medication usage.
Main Methods:
- Prospective study of 161 eyes with primary open-angle or pseudoexfoliative glaucoma undergoing consecutive surgeries by a single surgeon.
- Follow-up data at 1 year was analyzed for 70 eyes that underwent PT and 54 eyes that underwent TA.
Main Results:
- Both PT and TA significantly reduced intraocular pressure (IOP) from baseline.
- At 1 year, mean IOP was 13.3 +/- 3.4 mm Hg for PT and 14.2 +/- 3.9 mm Hg for TA, with no significant difference between groups (p > 0.1).
- Average medication use decreased in both groups, with no significant difference between PT and TA at 1 year.
Conclusions:
- Phacotrabeculectomy does not offer a significant advantage over trabeculectomy alone in terms of intraocular pressure control at one year.
- The addition of phacoemulsification to trabeculectomy does not appear to influence long-term IOP management in glaucoma patients.
