Abstract:
AIM: To evaluate the safety of the laser peripheral iridoplasty ( LPIP ) for the early-stage chronic primary angle-closure glaucoma ( ECPACG) .
METHODS:Sixty-five eyes of 36 patients with ECPACG received LPIP. At preoperative and postoperative, patients were examined with intraocular pressure ( IOP ) , anterior chamber, optical coherence tomography ( OCT) , visual acuity, visual field, fundus and complications. The mean follow-up was 18. 2±6. 7mo (ranged 12~24mo).
RESULTS: The preoperative average IOP were 23. 8±5.6mmHg, postoperative 1wk, 1, 3, 6, 12mo and in the last follow-up time the average IOP were 18. 7±3. 8, 17. 9±3. 2, 17. 6±3. 5, 18. 4±3. 7, 18. 6±3. 7, and 18. 6±7. 8mmHg. There was statistical difference comparing with preoperative (P<0. 05, decreasing average 6. 5±3. 1mmHg compared with the preoperative, the difference was statistically significant (t=5. 32, P<0. 05). Postoperative 1wk, 1, 3, 6mo, the trabecular-iris angle ( TIA500 ) and the angle opening distance at 500μm ( AOD500 ) had the statistical difference comparing with preoperative ( P <0.05). At Postoperative 1a and the last follow-up time, the TIA500 and AOD500 did not have statistical difference comparing with preoperative (P>0. 05). The postoperative visual acuity, visual field, fundus had not changed. There were no complications found.
CONCLUSION:LPIP is safe, and has the short time effect in the treatment of ECPACG. With elapse of time, the effect of LPIP is weakened. We can repeat the treatment.
