Abstract
Purpose:
To analyze the prevalence of uveitis in patients evaluated at a tertiary ophthalmic service in Teresina, PI
Methods:
A retrospective, cross-sectional, descriptive and epidemiological study was conducted based on the query of electronic medical records of patients treated at Hospital de Olhos Francisco Vilar (Eye Hospital Francisco Vilar) in the period from January 1st, 2006 to December 31st, 2011. There followed a search strategy on electronic medical records of the aforesaid hospital, looking up keywords that embraced "uveitis" and all its synonyms, besides the search for underlying diseases that could lead to it, being careful to insert the charts only once in the statistics. The following data were reported: gender, age, origin, underlying disease, and classifications related to the position, evolution, and clinical aspect. Each uveitis found was separated according to their underlying disease, then it was also created the groups "SDD" (without definite diagnosis) and "Other". The group "SDD" was used to discriminate the uveitis that had only ocular manifestation without alterations that were systemic or that were in the complementary exams, and the group "Other" was used to lease diseases that appeared only once and that were not in the research protocol.
Results:
403 records were included, noting that 3.2 out of every 1000 patients treated there had uveitis. The average age of patients was 42 years old, both (50.6% females and 49.4% males) affected similarly, with 61.5% coming from the capital. The most common underlying disease was toxoplasmosis, followed by the idiopathic uveitis with ocular manifestations only. As to the anatomical classification, 49.6% of them were posterior and only 3.5% were intermediate. Regarding the clinical aspects, 64% were granulomatous, 24.8% non-granulomatous, and 11.2% were not classifiable. According to the clinical progression, 41.4% were acute, followed by 30.8% chronic ones, 14.4% recurrent cases, and 13.4% of the patients did not keep medical care
Conclusions:
This survey found a prevalence of 3.2 cases of uveitis for every 1,000 patients evaluated, evidencing the relative frequency of uveitis found in this service, among which toxoplasmosis was the most prevalent followed by idiopathic uveitis with only ocular manifestations. Numerous other infectious and noninfectious causes with significant social impact as tuberculosis and syphilis were also identified.
