AIM: To investigate the short-term and mid-term effectiveness and safety of transscleral ciliary body photocoagulation in the treatment of high intraocular pressure after the removal of malignant glaucoma ciliary ring block.

METHODS: Retrospective study. A collection of 14 eyes of 14 patients with high intraocular pressure after ciliary ring block was lifted from 2016-10/2019-10 malignant glaucoma were treated with 810nm semiconductor diode laser transscleral ciliary photocoagulation. Follow-up 8.36±5.18mo, observation Best corrected visual acuity(BCVA), intraocular pressure and complications before and after surgery.

RESULTS: The intraocular pressure of 13.60±3.50mmHg at the last follow-up after treatment was different from 40.53±7.14mmHg before operation(P<0.05); there was no difference between the BCVA at the last follow-up postoperative and preoperative(P>0.05). All patients had no difference to the last follow-up and serious complications.

CONCLUSION: The 810nm semiconductor diode laser transscleral ciliary body photocoagulation is effective in the treatment of malignant glaucoma. It is easy to operate, has fewer complications, can effectively reduce intraocular pressure, and has little damage to the best corrected vision after surgery.
