BACKGROUND: Polymerase chain reaction (PCR) analysis is an important tool in the diagnosis of infectious uveitis. A retrospective, interventional study of PCR analysis of ocular fluid in suspected infectious uveitis cases between January 2014 to July 2016 was done. Nested, real-time and broad range PCR was performed for detection of the genome of Mycobacterium tuberculosis, herpes virus family, Chikungunya virus, Toxoplasma gondii, fungus, eubacterium and propionibacterium acne. RESULTS: Total of 100 cases included, mean age was 39...

BACKGROUND: Uveitis involving the posterior segment is a significant and potentially blinding condition. The diagnosis and treatment of patients with uveitis associated with tuberculosis remains controversial, and commonly, patients are systemically well. Use of the interferon-gamma release assays has added to the controversy, as the significance of a positive test may be uncertain. We aim to report the outcomes of anti-tuberculous treatment in a cohort of patients treated in Birmingham, for presumed "ocular tuberculosis", based on clinical findings, systemic assessment and specific testing for tuberculosis...

The molecular basis of intraocular tuberculosis (TB) is not well understood. In this study, we investigated the role of two constituents of viable Mycobacterium tuberculosis - Early Secreted Antigenic Target-6 (ESAT-6), and mycobacterial RNA- in inflammasome activation in the retinal pigment epithelium (RPE) - a key site of inflammation in intraocular TB. We found that ESAT-6 induced caspase-1 activation and inflammasome priming in mouse RPE cells, significantly more in wild-type than in Tlr2/3/4/7/9-/-, Myd88-/- and Nlrp3-/- RPE cells...

Importance: Eradication of systemic tuberculosis (TB) has been limited by neglected populations and the HIV pandemic. Whereas ocular TB often presents as uveitis without any prior evidence of systemic TB, the existing uncertainty in the diagnosis of TB uveitis may perpetuate missed opportunities to address systemic TB. Objective: To examine the clinical features of TB uveitis and the associations with response to antitubercular therapy (ATT). Design, Setting, and Participants: This retrospective multinational cohort study included patients from 25 ophthalmology referral centers diagnosed with TB uveitis and treated with ATT from January 1, 2004, through December 31, 2014, with a minimum follow-up of 1 year...

Lin Ho Wong, Endean Tan
Oculogyric crisis (OGC), frequently caused by medications such as antiemetics, antidepressants, and anti-epileptics, is an acute dystonic reaction of the ocular muscles. It consists of wide-staring gaze (lasting variably from seconds to minutes), seizures, and a widely-opened mouth. To date, there have been no reports of anti-tuberculosis medications such as rifampicin, isoniazid, pyrazinamide or ethambutol inducing OGC. It is of utmost importance to recognize this adverse reaction, which could be incorrectly diagnosed as an anaphylactic-like reaction...

Acute angle closure is usually thought to be secondary to pupillary block which is relieved by laser iridotomy. Anterior rotation of the ciliary body at the scleral spur following development of an inflammatory cilio-choroidal detachment may result in a presentation of acute angle closure. It is imperative to recognize this condition correctly, because the management is with cycloplegics and anti-inflammatory drugs, which is diametrically opposite to the treatment of primary angle closure. More importantly, it has been reported as a consequence of serious systemic disease such as HIV infection and Vogt Koyanagi Harada(VKH) syndrome...
