RESUMEN
PURPOSE: To evaluate if topical povidone iodine (alone (PI) or combined with dexamethasone (PI-DXM)) is superior to placebo for treating adenoviral conjunctivitis (AC). METHODS: A systematic review was performed according to Preferred Reporting Items for the Systematic Review and Meta-Analyses (PRISMA) Statement. An electronic search was made on PubMed, Embase and Cochrane Library. Randomized control studies that compared PI or PI-DXM with placebo were included. At least three researchers were involved in all phases. Primary outcomes were AC duration and the number of clinical resolutions during the first week. Secondary outcomes were conjunctival redness and serous discharge one week after starting treatment and the rate of AC complications. RESULTS: Only five studies met the inclusion criteria. PI-DXM reduced the duration of the disease by 2.4 days (IC95% 4.09-0.71), however this result was based only in one study. PI and PI-DXM did not modify the probability of clinical resolution during the first week; relative risk (RR) = 1.77 (IC95% 0.63-4.96) and 1.70 (IC95% 0.67-4.36). The impact of PI on the probability of pseudomembranes could not be estimated. PI-DXM did not influence the risk of developing subepithelial infiltrates RR = 0.73 (IC95% 0.02-33.38). CONCLUSIONS: At this time there is great uncertainty about the usefulness of PI on the course of adenoviral conjunctivitis. PI-DXM may have a small effect on AC duration. To make future reviews possible, it is important to standardize the way in which these results are reported. Futures studies should include etiological confirmation, unit of study (eyes vs patients) and report on those aspects that are more relevant for patient quality of life (duration of the disease, development of complications: pseudomembranes and subepithelial infiltrates).

Cyclodialysis is the result of the separation of the longitudinal ciliary muscle fibers from the scleral spur, which creates an abnormal pathway for aqueous humor drainage that may lead to ocular hypotony. For many years cyclodialysis was considered a treatment option for glaucoma. However, today it usually occurs as a complication of blunt trauma or more rarely as a complication of anterior segment ocular surgery. Ocular hypotony can lead to cataract development, optic disk swelling, refractive changes, and several retinal complications, making accurate identification and timely intervention of the cleft mandatory. Traditionally gonioscopy was the only available technique to diagnose and localize the cleft. However, other tests such as optical coherence tomography, magnetic resonance imaging, transillumination, and specially ultrasound biomicroscopy are now available for the diagnosis of cyclodialysis. Multiple treatment options are also available for this condition. Although medical treatment can be effective to close small clefts, surgery is needed in most patients to restore ocular pressure.

The purpose of this study is to measure the impact of tamsulosin intake on five postoperative cataract surgery complications (toxic anterior segment syndrome, rebound uveitis, retinal detachment, macular edema, and postoperative endophthalmitis). This retrospective cohort study was conducted at University Hospital of Henares. The study included 660-eyes of 660 patients submitted to cataract surgery at the ophthalmology unit of Hospital del Henares (Madrid) between 2 March 2009 and 28 February 2010. Extracapsular cataract extraction, combined glaucoma and cataract surgery phacovitrectomy, posterior capsule rupture and zonular damage were considered exclusion criteria. Clinical charts were reviewed during July 2012. Patients were divided in two groups (exposed and non-exposed to tamsulosin). Cumulative incidence of toxic anterior segment syndrome, rebound uveitis, retinal detachment, macular edema and postoperative endophthalmitis were compared in both groups. Rebound uveitis (relative risk [RR] 3.39; confidence interval [CI] 1.63-7.08) and macular edema (RR 4.15; CI 1.06-16.22) were more common in the tamsulosin-exposed group. Retinal detachment had a similar incidence in both groups. We observed no cases of endophthalmitis or toxic anterior segment syndrome in either of the two groups. Tamsulosin exposure in this cohort was associated with a higher risk of rebound uveitis and macular edema but the other three studied postoperative complications had a similar incidence in both groups.
