ABSTRACT To analyse the pattern of uveitis in a referral centre in Tunisia, North Africa.
The study included 472 patients with uveitis examined at the Department of Ophthalmology of Monastir (Tunisia) from January 1992 to August 2003. All patients had a comprehensive ocular and systemic history, including an extensive review of medical systems. Complete ophthalmic examination was performed in all cases, including best-corrected Snellen visual acuity, slit-lamp examination, applanation tonometry, and dilated fundus examination with three-mirror lens. Standard diagnostic criteria were employed for all syndromes or entities of uveitis.
The mean age at onset of uveitis was 34 years. The male-to-female ratio was 1:1.1. Uveitis was unilateral in 282 patients (59.7%) and bilateral in 190 patients (40.3%). Anterior uveitis was most common (166 patients; 35.2%), followed by posterior uveitis (133 patients; 28.2%), panuveitis (100 patients; 21.2%), and intermediate uveitis (73 patients; 15.5%). A specific diagnosis was found in 306 patients (64.8%). The most common cause of anterior uveitis was herpetic uveitis (56 patients; 33.7%). Toxoplasmosis was the most frequent cause of posterior uveitis (51 patients; 38.3%). Intermediate uveitis was most commonly idiopathic (63 patients; 86.3%). Behçet's disease was the most common cause of panuveitis (36 patients; 36%), followed by Vogt-Koyanagi-Harada (VKH) disease (15 patients; 15%). A total of 16 patients (3.4%) suffered from blindness, and 59 (12.5%) from uniocular blindness.
In a hospital population in Tunisia, the most common causes of uveitis were Behçet's disease, herpes simplex infection, toxoplasmosis, and VKH disease.

    ABSTRACT: Abstract Purpose: To report the trends in etiology of patients with anterior uveitis (AU) in Singapore over 6 years. Methods: A retrospective review of the clinical records of all new patients who presented with anterior uveitis to the uveitis subspecialty clinic from 2005 to 2010 at Tan Tock Seng Hospital, Singapore. Results: There were 552 new cases of AU. This comprised 59.5% of a total of 928 new patients diagnosed with uveitis from 2005 to 2010. The mean age was 48.0 ± 17.2 years. There was a male predominance (62.5%), with a male:female ratio of 1.7:1. The majority were of Chinese ethnicity (69%), followed by Malays (13.2%). Most cases were unilateral (79.5%) and idiopathic (50.4%). Common etiological causes included Fuchs heterochromic iridocyclitis (FHI) (5.6%), ankylosing spondylitis (AS)-related AU (5.1%), herpes simplex virus (HSV) (4.7%), and herpes zoster virus (HZV) (4.5%). There were increasing trends in AS-related AU from 3.2% in 2008 to 6.5% in 2010, and psoriasis-associated AU from 1.7% in 2005 to 4.0% in 2008. There were decreasing trends in the incidence of FHI from 10.6% in 2006 to 4.7% in 2009. No change in incidence of viral etiologies was noted, but cytomegalovirus-related immune-recovery uveitis (IRU) comprised 7.4%. IRU showed an increasing trend from 1.7% in 2005 to 11.9% in 2007, then decreased to 3.3% in 2010. Using the Pearson chi-square test, there was no statistically significant association between ethnicities (Chinese, Malay, Indian) comparing infectious and noninfectious cases (p = 0.788), idiopathic and nonidiopathic cases (p = 0.170), or between the various etiologies of uveitis (p = 0.168). Conclusions: AU was the predominant form of uveitis seen at our centers. Infectious etiologies (18.5%) are the most common among nonidiopathic cases, with herpes viruses (9.2%) being most prevalent. Despite increased use of polymerase chain reaction (PCR) in the detection of microbial and viral DNA, there was no overall increase in detection of infectious causes for uveitis. The changes in CMV-related immune recovery uveitis from 2005 to 2010 could reflect a change in HIV management in Singapore.

    ABSTRACT: Purpose: To describe the clinical characteristics of Chinese patients with intermediate uveitis (IU). Methods: Retrospective review of patients with IU with at least 6 months follow-up. Results: Seventy patients were identified and the mean follow-up was 59.7 months. The mean age at presentation was 33.1 years. Fifteen (21.4%) patients had disease onset before the age of 18 years; 91.4% of IU cases were considered idiopathic after investigations. At the last follow-up, 85 (74.6%) eyes retained vision of at least 20/40. Poor visual outcome was significantly associated with poor presenting visual acuity (p = .002), presence of epiretinal membrane or atrophic macular changes (p = .003), persistent cystoid macular edema (p = .015), and increased disease duration (odds ratio = 1.015 per month, p = .002). Pediatric patients were more likely to have bilateral (p = .003) and chronic disease (p < .001). Conclusions: IU in Chinese patients was mainly idiopathic, with good visual outcomes in most patients after appropriate treatment.

    ABSTRACT: A 17-year-old female presented to our hospital with fatigue, arthralgia and fever associated with non-granulomatous anterior uveitis in the left eye. Blood tests revealed renal failure and a renal biopsy showed acute tubulointerstitial nephritis. Findings were consistent with tubulointerstitial nephritis and uveitis (TINU) syndrome. The patient received systemic corticosteroids for 2 months as well as dexamethasone and mydriatic drops. Bilateral non-granulomatous anterior uveitis occurred 10 days after prednisone discontinuation, and was treated with topical steroids; however, uveitis recurred several weeks later. Bilateral anterior chamber inflammation was associated with neuroretinitis in the right eye. Extensive posterior synechiae precluded fundus examination of the left eye. The posterior segment manifestations responded to systemic prednisone, which was slowly tapered. The final visual outcome was favorable. TINU syndrome may rarely manifest with neuroretinitis.
