          We conducted an institutional-based retrospective study on 308 uveitic patients and analyzed the pattern of uveitis in Northeastern India. Anterior uveitis was the most common type (47.07%) followed by posterior (29.87%), intermediate (12.98%) and panuveitis (10.06%). Toxoplasmosis (40.21%) had the highest incidence among posterior uveitis cases. Harada's form of Vogt Koyanagi Harada's disease is a frequent occurrence in this subset of the population.

          Changing patterns of uveitis.

          We conducted a retrospective analysis of 600 patients with uveitis seen at the Estelle Doheny Eye Center to determine the frequency of occurrence of the various forms of uveitis and to see if the causes of uveitis have changed as compared with previous studies. In 402 cases (67.0%) we established a specific diagnosis based on history, physical findings, and laboratory studies: 167 cases (27.8%) involved primarily the anterior segment, 230 (38.4%) the posterior segment, and 111 (18.4%) occurred as panuveitis. Intermediate uveitis (pars planitis) was the single most frequently diagnosed uveitic entity and accounted for 92 cases (15.4%). We compared our findings with those of previously published studies and found that, as new diseases occur and improved diagnostic techniques become available, the differential diagnosis of uveitis continues to change.

            Global variation and pattern changes in epidemiology of uveitis.

            Uveitis, a complex intraocular inflammatory disease results from several etiological entities. Causes of uveitis are known to vary in different populations depending upon the ecological, racial and socioeconomic variations of the population studied. Tropical countries are unique in their climate, prevailing pathogens and in the existing diseases, which further influence the epidemiological and geographical distribution of specific entities. We provide an overview of the pattern of uveitis of 15221 cases in 24 case series reported from several countries over 35 years (1972-2007) and we integrate it with our experience of an additional 8759 cases seen over six years (1996-2001) at a large community-based eye hospital. Uveitis accounted for 0.8% of our hospital-based outpatient visits. The uveitis was idiopathic in 44.6%, the most commonly identified entities in the cohort included leptospiral uveitis (9.7%), tuberculous uveitis (5.6%) and herpetic uveitis (4.9%). The most common uveitis in children below 16 years (616 patients; 7.0% of the total cohort) was pediatric parasitic anterior uveitis, (182 children, 29.5% of the pediatric cohort), whereas the most common uveitis in patients above 60 years (642 patients; 7.3% of the total cohort) was herpetic anterior uveitis, (78 patients, 12.1% of the elderly cohort). Etiologies varied with the age group of the patients. As in other tropical countries, a high prevalence of infectious uveitis was seen in this population.

              Pattern of uveitis in a referral eye clinic in north India.

              To report the pattern of uveitis in a north Indian tertiary eye center. A retrospective study was done to identify the pattern of uveitis in a uveitis clinic population of a major referral center in north India from January 1996 to June 2001. A standard clinical protocol, the "naming and meshing" approach with tailored laboratory investigations, was used for the final diagnosis. 1233 patients were included in the study; 641 (51.98%) were males and 592 (48.01%) females ranging in age from 1.5 to 75 years. The anterior uveitis was seen in 607 patients (49.23%) followed by posterior uveitis (247 patients, 20.23 %), intermediate uveitis (198 patients, 16.06%) and panuveitis (181 patients, 14.68%). A specific diagnosis could be established in 602 patients (48.82%). The infective aetiology was seen in 179 patients, of which tuberculosis was the commonest cause in 125 patients followed by toxoplasmosis (21 patients, 11.7%). Non-infectious aetiology was seen in 423 patients, of which ankylosing spondylitis was the commonest cause in 80 patients followed by sepigionous choroidopathy (62 patients, 14.65%). Tuberculosis and toxoplasmosis were the commonest form of infective uveitis, while ankylosing spondylitis and serpiginous choroidopathy were commonly seen as the non-infective causes of uveitis in North India.
