[Mid-term and long-term clinical effect of micro-perforating trabecular surgery with amniotic membrane implants on open angle glaucoma].

OBJECTIVE

To evaluate the mid-term and long-term clinical effect and complication of micro-perforating trabecular surgery (MPTS) with amniotic membrane implants on open angle glaucoma (OAG).

METHODS

Thirty OAG patients (49 eyes) were treated with MPTS with amniotic membrane implants. Visual acuity, intraocular pressure, visual field, type of blebs, and complications were recorded pre-and post-operatively.

RESULTS

Patients were followed up for 6~24(15.93+/-2.35) months. The mean IOPs before the operation and 24 months after the operation were (36.84+/-11.02) mmHg and (18.24+/-1.34) mmHg, respectively (P=0.000). The mean numbers of anti-glaucoma drugs used before and after the operation were (2.76+/-0.69) and (0.59+/-0.89), respectively (P<0.05). The global index of the early to moderate glaucomatous visual field loss was significantly improved postoperatively (P<0.05), and no significant difference was found in aggressive glaucoma pre- and postoperatively. Functional filter bleb was formed in 70.8% patients 24 months after the operation. The complete success rate and quality success rate were 75.5% (37/49) and 93.9% (46/49), respectively. There was no significant change in visual acuity pre- and postoperatively and no severe complication was found.

CONCLUSION

Micro-perforating trabecular surgery with amniotic membrane implants is effective and safe for OAG, with reliable effect on lowering IOP in the mid-term and long-term.
