Abstract
Purpose:
To determine the distribution of visual acuity and its associated factors in a population with high proportion of indigenous people.
Methods:
Chart review of patients with anterior segment surgery and diagnosis of cyclodialysis between 2001 and 2007 were obtained. Retrospective case series, observational study. STATA 8.0 was used for grapics and descriptive statistics.
Results:
54 files with cyclodialysis diagnosis were recolected, 18 were excluded. 36 were analyzed, 15 male and 21 female. The causes were: 21 due to trabeculectomy, 7 extracapsular cataract surgery, 4 phacoemulsification, 2 combination of trabeculectomy and phacoemulsification and 2 Ahmed valvular implantation. Average intraocular pressure was 4 mmHg (0-10 mmHg). The incidence of cyclodialysis is 0.5 per 100 cases. Visual acuity varied from 20/20 to no light perception. Mean age was 56.57 years (7-84 years).
Conclusions:
The incidence of cyclodialysis is 0.5 per 100 cases during the study period.
