The Spectrum of Presumed Tubercular Uveitis in a Referral Eye Clinic in Qatar

Abstract

ABSTRACT Purpose To analyze the clinical spectrum of patients with presumed tubercular uveitis in a referral eye clinic in Qatar. Methods We retrospectively reviewed the clinical records of 50 patients (80 eyes) diagnosed with presumed ocular tuberculosis who presented to the uveitis clinic, department of Ophthalmology Hamad Medical Corporation, Qatar, from January 2014 till December 2019. Results Mean age at presentation was 34.5 ± 9.3 years. Forty one patients were males (82%) and 30 patients had bilateral involvement (60%). Forty eyes (50%) had posterior uveitis, 21 eyes (26.3%) intermediate uveitis, 11 eyes (13.7%) panuveitis, and 8 eyes (10%) anterior uveitis. Ocular findings included vitritis in 82.5% of eyes, retinal vasculitis in 46.3% (92% of which were occlusive in nature), multifocal choroiditis in 18.8%, serpiginous-like choroiditis in 11.3%, Most common complications at presentation or during follow-up included macular edema in 32 eyes (40%), preretinal or optic disc neovascularization in 29 eyes (36.3%) and vitreous hemorrhage in 17 eyes (21.3%). Anti-tubercular treatment was provided to 46 patients (92%). Systemic corticosteroids and corticosteroid sparing agents were associated, respectively, in 39 patients (78%) and 14 patients (28%). After 1 year of follow up, inflammation was controlled, with a significant improvement in visual acuity (p < 0.0001). Conclusions In Qatar, tubercular uveitis has a broad spectrum of ocular features, with posterior and intermediate uveitis being the most common anatomic forms. Vitritis, multifocal choroiditis without or with a serpiginous-like pattern, and occlusive retinal vasculitis are the most common ocular findings. Main sight-threatening ocular complications are macular edema, posterior segment neovascularization, and vitreous hemorrhage.
