ABSTRACT.Purpose: To describe the clinical features of post-streptococcal uveitis (PSU) and examine management strategies in the treatment of this under-recognized condition. Methods: Patients were identified from the world literature using the Pubmed search engine. We examined two new cases of post-streptococcal intermediate uveitis. The epidemiology, immune mechanisms, clinical features, investigations, treatments and visual outcomes were examined and recorded. Results: We reviewed 11 patients including our own two cases. There was a statistically significant seasonal difference in antistreptolysin-O titres (ASOT), and age-related ASOT was identified. Of the 11 patients, eight (72.7%) had anterior uveitis, two (18.2%) had intermediate uveitis and one (9.1%) had panuveitis. Their ages ranged from 5 to 56 years (mean 17 years). The majority of cases had significantly elevated ASOT; most patients were treated with topical steroids and oral antibiotics and four cases underwent adenotonsillectomy. The visual prognosis was good in most cases. Conclusions: Uveitis may be the sole presenting clinical feature, or it may occur in combination with other features of post-streptococcal infection. Ophthalmologists should be aware of the clinical features of PSU and maintain a high level of suspicion, particularly in childhood uveitis.

Purpose: To compare intravitreal bevacizumab (IVB) injection versus macular photocoagulation (MPC) or a combination of intravitreal bevacizumab and intravitreal triamcinolone acetonide (IVB/IVTA) injection in improving visual acuity (VA) of patients with primary diabetic macular oedema (DMO).
Methods: The following databases were searched: Medline (1950 – December week 3, 2009), The Cochrane Library (Issue 4, 2009), EMBASE (up to 24 December 2009), and the TRIP database (up to 23 December 2009), using no language or other limits. Randomized controlled trials were included that consisted of patients with primary DMO (not with refractory DMO), those comparing IVB injection with MPC or IVB/IVTA injection, those reporting VA outcomes, and those having a minimum follow‐up of 6 weeks.
Results: In the four randomized clinical trials comparing IVB injection with MPC, IVB injection demonstrated significantly greater improvement in VA at 6 weeks, but not at 12 weeks. In the three randomized clinical trials comparing IVB injection with IVB/IVTA, IVB injection demonstrated greater improvement in VA at 6 weeks but the benefit was again no longer significant at 12 weeks. No adjunctive effect of IVTA was demonstrated.
Conclusions: Intravitreal bevacizumab injection is effective in improving VA in patients with primary DMO for 6 weeks, but the benefits are no longer present 12 weeks following the injection.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
