Abstract:AIM: To observe the clinical efficacy and safety in the treatment for refractory glaucoma by two kinds of cyclodestructive procedures.
METHODS: A retrospective study of 50 patients(50 eyes)with refractory glaucoma diagnosed in our hospital between January 2018 and October 2018. Ultrasound cyclo plasty(UCP)were performed on 30 eyes and cyclocryotherapy were performed on 20 eyes, introcular pressure(IOP), pain grade scores and complications after operation were followed up.
RESULTS: The average IOP of the UCP group on 1d, 1wk, 1mo and 3mo were 29.27±10.40, 23.87±8.61, 25.27±9.95, 23.70±10.06mmHg compared with 43.97±10.39mmHg before operation. The average IOP of the cyclocryotherapy group on 1d, 1wk, 1mo and 3mo were 22.15±7.78, 20.80±8.44, 22.50±7.12, 24.20±8.43mmHg compared with 47.30±8.53mmHg before operation. The IOP in both group was significantly reduced(P<0.01). The pain grade scores of patients in the UCP group at 1d, 1wk, 1mo and 3mo after surgery were significantly lower than those before operation(P<0.05), but there was no significant difference in the cyclocryotherapy group at 1d after surgery(P>0.05). There were no serious complications in the UCP group, four eyes appeared conjunctival hyperemia and one eye appeared superficial punctuate keratitis; but there were 16 eyes(80.00%)in the cyclocryotherapy group: ten eyes appeared conjunctival hyperemia and six eyes appeared anterior chamber hemorrhage.
CONCLUSION: UCP is safe and convenient surgery for refractory glaucoma, and has significant effect on reducing intraocular pressure, alleviating ocular pain and decreasing complications.
