Abstract
Purpose :
To evaluate the ocular findings, prevalence and causes of visual impairment and blindness of patients attending a low-vision rehabilitation service in Londrina City, Brazil.
Methods :
A Cross-sectional observational study was performed evaluating patients attending a low-vison rehabilitation service in Londrina City, Brazil, during 2017. The participants were evaluated according to age, gender, visual impairment characteristics, and ocular findings. The
data were submitted to statistical analysis.
Results :
In total, 111 patients were evaluated. The average age was 39,5 years; 55,8% were male and 44,2% female. Bilateral blindness (VA<0,05) was observed in 89%, subnormal vision (VA<0,3) in 11%, and 74% presented visual impairment for more than 10 years. Fundoscopic alterations
were observed in 88%. Acquired visual deficiency occurred in 33%, irreversible congenital ocular manifestations in 52%, and potentially reversible ocular diseases in 15% of patients. The main causes of visual impairment were retinopathies (61,2%), glaucoma (14,4%), and
neuropathies/anterior segment diseases (12,6%).
Conclusions :
Fundoscopic alterations were the most prevalent ocular finding observed and retinal diseases were the main cause of visual impairment.
