Purpose: To report demographic and clinical profiles of children with uveitis in theTurkishpopulation., Methods: The data of the pediatric uveitis cases in the nation wide uveitis database were analyzed., Results: The study included 697 eyes of 442 patients with a meanage of 10.8 ± 3.8 years. There were 333 patients (75.3%) with non-infectious uveitis and 69 patients (15.6%) with infectious uveitis. Pars planitis (20.1%) was leading clinical form followed by idiopathic cases with uveitis other than pars planitis (18.8%), juvenile idiopathic arthritis(JIA) related uveitis (12.4%), Behçet uveitis (9.3%) and toxoplasma retinochoroiditis (7.9%). Ocular involvement was unilateral in 187 patients (42.3%) and bilateral in 255 patients (57.7%). The most common anatomiclocation of uveitis was anterior uveitis (39.1%), followed by intermediate uveitis (29.4%), panuveitis (16.1%) and posterior uveitis (15.4%)., Conclusion: The most common systemic association was JIA in the younger children and Behçet disease in the older children.

Purpose: To analyze the referral patterns and clinical features of uveitis in tertiary eye care centers in Turkey., Methods: Uveitis services of eight university clinics collected data on uveitis patients who presented during 2004. Data were collected on a form including a questionnaire on socio-demographic and clinical features which were documented at presentation., Results: A total of 761 patients (1187 eyes) with a mean age of 35.5 years were included in the study. Male to female ratio was 1.04:1. The majority of patients (89.6%) were from an urban population, 53% were referrals and 43% had had uveitis for more than one year. The most common type of uveitis was anterior uveitis (52.5%) followed by panuveitis (28.1%), posterior uveitis (12.7%) and intermediate uveitis (6.7%). In 56.8% of patients an etiological classification was established. The most common etiology was Behcet's disease (32.1%), followed by Fuchs' heterochromic iridocyclitis (5.1%) and ocular toxoplasmosis (4.7%). Among 48 pediatric patients uveitis associated with juvenile idiopathic arthritis and ocular toxoplasmosis both having equal frequencies (12.5%) were the most common diagnosis. These were followed by Behcet's disease with juvenile-onset (10.4%). At the time of presentation, 6.25% of the patients were legally blind (having visual acuity less than 0.1 in the better seeing eye)., Conclusion: Compared to the uveitis series reported from other countries, Behcet uveitis was the leading cause of uveitis in this series. Uveitis associated with juvenile idiopathic arthritis and ocular toxoplasmosis were the most common cause of uveitis in childhood. On the other hand, entities like acquired immunodeficiency syndrome-related uveitis, presumed ocular histoplasmosis and Birdshot retinochoroidopathy were rare.

The purpose of this study was to investigate the referral patterns, demographic and clinical features, and visual prognosis of patients with sarcoid uveitis seen at 2 tertiary eye care centers in Turkey. A retrospective study was made of 44 patients with uveitis associated with biopsy-confirmed or presumed sarcoidosis. Thirty-four patients (77%) were female and 10 (23%) were male. The mean age at onset of uveitis was 39.8 years. Twenty-seven patients (61%) were referred without a diagnosis of sarcoidosis and 17 (39%) patients were referred with a diagnosis of systemic sarcoidosis. The duration of uveitis prior to referral was 2-15 years in 52% of the patients in the former group. At presentation, 37 patients (84%) had bilateral and 7 patients (16%) had unilateral uveitis, and 17 patients (39%) had only anterior uveitis. The most common ocular findings were granulomatous keratic precipitates, persistent posterior synechiae, and snowball vitreous opacities. Kaplan-Meier survival analysis estimated the risk of recurrence as 30% at 6 months and 61% at 5 years. New complications developed in 18 patients. Potential visual acuity was better than 0.4 in 80% of eyes. The estimated risk of losing potential visual acuity by at least 2 lines was 7% at 6 months and 43% at 5 years. None of the eyes lost useful vision (> 0.1) under the authors' care. The referral patterns suggest underrecognition of sarcoidosis as a cause of uveitis in Turkey. The demographic and clinical features of these patients were mostly similar to those reported from other countries, suggesting that the diagnosis may not be difficult in Turkish patients but requires an increased awareness of the disease in this population.

Purpose: We aimed to describe the demographic and clinical features, ocular manifestations, complications, visual prognosis, and treatment in a large population of Turkish patients with Behçet uveitis. We also aimed to compare visual prognosis between male and female sex and between patients who presented before and after 1990., Design: Observational case series., Methods: A retrospective study of 880 consecutive patients (1,567 eyes) with Behçet uveitis seen at the Uveitis Service, Department of Ophthalmology, Istanbul Faculty of Medicine, Istanbul University, from 1980 to 1998. All patients met the classification criteria of the International Study Group for Behçet's Disease. Information on the patient's sex, age at onset of uveitis, ocular features, ocular complications, visual acuity, and systemic treatment was collected., Results: Five hundred ninety-nine patients (68%) were male and 281 (32%) were female. The mean age at onset of uveitis was 28.5 years in male and 30 years in female patients. Ocular involvement was bilateral in 78.1% and unilateral in 21.9% of the patients. Panuveitis was the most common form in both sexes. Fundus lesions as well as sight-threatening complications were more common in males. At the beginning of the follow-up, potential visual acuity was 0.1 or less in 30.9% of eyes in males and 24.2% of eyes in females. Kaplan-Meier survival analysis estimated the risks of losing useful vision (>0.1) at 5 and 10 years for males and females as 21% vs 10% and 30% vs 17%, respectively. Male patients who presented in the 1990s had a significantly lower risk of losing vision compared with male patients who presented in the 1980s., Conclusion: Behçet uveitis starts frequently around the end of the third decade and has a male predominance. The disease is more severe and the risk of losing useful vision is higher in males than in females. However, this risk has been significantly reduced in the 1990s.

Purpose: To describe the demographic and clinical profiles of uveitis patients seen at secondary and tertiary care centers in Turkey.Methods: A nationwide web-based registry of patients with uveitis was initiated in November 2008. We analyzed data from a single baseline registry-enrollment visit.Results: In 33 centers, 6967 eyes of 4863 consecutive patients were registered. The mean age at presentation was 36.6 ± 15.7 (1-92) years; 51.3% were male. Behçet disease was the leading diagnosis (24.9%), followed by ankylosing spondylitis and/or HLA-B27-associated anterior uveitis (9.7%), toxoplasmosis (7.1%), Fuchs uveitis (6.3%), and presumed herpetic anterior uveitis (6.0%). Visual acuity was 0.1 or worse in 22% of eyes. The most common ocular complications were posterior synechiae (16.2%) and cataract formation (16.2%).Conclusions: Behçet disease is still the most common non-infectious etiology in Turkish uveitis patients, while ocular toxoplasmosis and herpetic anterior uveitis are the most common infectious uveitic entities.

Purpose: To describe Turkish patients with Fuchs uveitis syndrome (FUS). Design: Retrospective observational case series. Methods: We reviewed the records of 172 patients with FUS seen at Istanbul University, Istanbul Faculty of Medicine, Department of Ophthalmology, between January 1995 and July 2007. The main outcome measures were demographic features, clinical findings at presentation, laser flare photometry values, risk of new complications, and rate of decreased vision. Results: The mean age was 29.5 + 8.4 years. Male-to-female ratio was 1:1.3. Nine patients (5.2%) had bilateral involvement. The diagnosis of FUS had been made in only 10 of 115 (8.7%) referrals. Clinical findings at presentation included diffuse keratic precipitates (medium-sized round in 74.6%, fine-stellate in 22.1%), anterior chamber cells (74%), diffuse iris atrophy without hypochromia (48.6%), heterochromia (39.8%), iris nodules (32%), cataract/pseudophakia (69.1%), vitreous cells (71.8%), elevated intraocular pressure (12.7%), and chorioretinal scars (7.7%). The mean flare was 8.4 + 3.1 photons/ms in eyes with FUS and 3.7 + 0.8 photons/ms in the fellow eyes (P < .001). Hyperfluorescence of the optic disc was the only fluorescein angiographic finding, detected in 7 of 32 eyes (22%). Kaplan-Meier analysis estimated risks of cataract formation and intraocular pressure elevation as 42% and 17%, respectively, at 4 years. The rate of decreased visual acuity by 2 lines or more was 0.06/eye-year. Conclusions: The referral patterns suggest that FUS is frequently misdiagnosed in Turkish patients. Diffuse medium-sized round keratic precipitates, low flare readings, iris stromal atrophy without hypochromia, and vitreous opacities in the absence of macular edema are more often helpful clues to the diagnosis than heterochromia.
