AIM: To evaluate the treatment protocols of primary angle-closure glaucoma(PACG)in persistent high ocular hypertension.

METHODS: The curative effects of 31 cases(32 eyes)with PACG in persistent high ocular hypertension were retrospectively analyzed. All cases were performed different surgical therapy.

RESULTS: For all cases, the intraocular pressure(IOP)was reduced to normal and the visual acuity was increased to some extent with no severe complications. Compared to the preoperative visual acuity which was hand movement before the eye to 0.1, the postoperative visual acuity was increased to 0.1 to 0.8. The mean IOP was reduced from 48.6mmHg preoperatively to 11.5mmHg 1 month postoperatively.

CONCLUSION: In order to reduce the high risk of operation and receive the optimal visual function, paracentesis seems to be necessary in controlling IOP in PACG patients with persistent high IOP. Anti-glaucoma operation was recommended to be performed when the cornea was clear.
