Abstract

Objective: To evaluate the initial outcomes and some factors affecting the anatomical results of treatment of cyclodialysis after ocular blunt trauma. Subjects and research methods: A prospective descriptive study without a control group on 60 eyes diagnosed with cylodialysis after ocular blunt trauma treated at the Trauma department and outpatient clinic of Vietnam National Eye Hospital from 01/ 2017 to 07/2018. Results: Most patients were male, the ratio male / female was approximately 6/1. The average age was 39,0 ± 12,3, most of them were in the groups of 31 – 50 years old. The average visual acuity (VA) pre – treatment was 0.2±0.3, after 3 weeks it was 0.08±0.16 and after 3 months it was 0.05±0.08. The average intraocular pressure (IOP) pre - treatment was 14.3±4.7 mmHg. After 3 months of treatment, the average IOP was 19.9 ± 2.9 mmHg. The percentage of patients with high IOP after 3 weeks of treatment was 8.3%. The proportion of hypotony maculopathy was 36,7%. IOP and the depth of cyclodialysis cleft were inversely correlated (r=-0.4, p=0.0015). Factors affecting the anatomical outcome included initial depth of cyclodialysis cleft, initial grade of cyclodialysis, hypotony maculopathy, and pre- treatment IOP. Age, gender, time from injury to treatment and pre - treatment visual acuity had no effect on the anatomical outcome. Conclusion: Cyclodialysis is a serious injury in ocular blunt trauma. Treatment of cyclodialysis depend on the grade and associated injuries. Some factors can be used to prognosis the anatomical outcome.
