Purpose: To compare the surgical outcomes of non-penetrating deep sclerectomy in Exfoliative Glaucoma (ExG) and Primary Open-angle Glaucoma (POAG)patients.
Patients and Methods: Deep sclerectomy performed in 20 eyes with ExG and 25 eyes with POAG. Postoperative intraocular pressure (IOP), number of glaucoma medications, visual acuity, surgical success rate and complications were assessed for 12 months. Complete success was defined by the achievement of postoperative IOP < 21 mmHg without medication.
Results: The mean postoperative IOP was significantly lower (P < 0. 05) in ExG and POAG eyes than preoperative. The mean IOP was 17. 6 + 3. 5 mmHg in ExG eyes and 16. 1 + 4. 6 mmHg in POAG eyes. At 12 months, complete success had been achieved in 45% of ExG eyes and 40% of POAG eyes. Qualified success had been achieved in 45% of ExG eyes and 52% of POAG eyes. No statistically significant differences in visual acuity, number of postoperative glaucoma medications, visual field changes and number of complications were found in ExG eyes and POAG eyes.
Conclusions: Deep sclerectomy is effective in controlling IOP, lowers the need for postoperative medications, and lowers the rates of serious complications in both ExG and POAG eyes.
