Best-corrected visual acuity(BCVA), intraocular pressure(IOP), the main complications following surgery, and indentation gonioscopy and angle parameters measured using UBM were documented preoperatively and postoperatively.· RESULTS: The improvement in BCVA in the phacoemulsification group was significantly greater than in the combined group(P 【0.05). IOP in the phacoemulsification group was slightly higher than in the combined group following 1wk of follow-up(P 【0.05),whereas there was no significant difference between the two groups at the latter follow-up(P 】0.05).Phacoemulsification alone resulted in a slight increase in the trabecular ciliary processes distance compared with the combined surgery(P 【0.05), whereas the other angle parameters showed no significant difference between the groups. Complications in combined group were greater than phacoemulsification only group.·CONCLUSION: Both surgeries effectively opened the drainage angle and deepened the anterior chamber, and IOP was well controlled postoperatively. However,phacoemulsification showed better efficacy in improving visual function and showed reduced complications following surgery.展开更多

It is unclear whether this laser treatment is equally efficient in managing patients with severe APAC. This study aimed peripheral iridotomy (LPI) on patients with refractory APAC, therapy. to evaluate the IOP-lowering efficacy of ALPI and laser who have previously responded poorly to intensive medical Methods Thirty-six patients (8 men and 28 women) were identified as medically refractory APAC, who still had ocular pain, red eye, hazy cornea, closed anterior chamber (AC) angle, and lOP of not less than 21 mmHg after two days or more of anti-glaucoma medication. All enrolled patients underwent ophthalmologic examinations including measurement of visual acuity (VA), best corrected VA (BCVA), lOP, biomicroscopy, and gonioscopy followed by ALPI immediately in the APAC eye and LPI in both eyes. Results All patients were affected unilaterally, with average age of (54.6±11.7) (range, 37.0-75.0) years old. The mean lOP value of the affected eyes dropped from (31.6±7.7) (range, 21.0-39.0) mmHg at enrollment to (18.4±8.7) (range, 10.0-27.0) mmHg 2 hours after ALPI. At follow-up day 7, the mean lOP value maintained at (14.8±4.2) (range, 9.0-21.0) mmHg, which was significantly different (P=0.000) compared with baseline. The average decrease of lOP in the APAC eyes was (16.8±7.4) (range, 12.0-21.0) mmHg. At follow-up three years later, the mean lOP of the APAC eyes stabilized at (16.3±3.2) (range, 9.0-20.0) mmHg with at least 180° of AC angle opened. Conclusion ALPI and LPI lower the lOP of medically refractory cases of APAC though they have responded poorly to anti-glaucoma medication.展开更多
