Limited information is available regarding the epidemiology of uveitis. Worldwide epidemiologic studies may help the clinician in the management of patients with inflammatory ocular diseases, enabling the comparison of different uveitis entities.

Manifestations of herpetic ocular disease in our patients are comparable with other published series. However, the rate of ocular complications and recurrences during follow-up were higher compared with other series.

In eyes with rhegmatogenous retinal detachment treated with vitrectomy and gas or silicone oil tamponade, retinal displacement may occur despite successful reattachment. Type of intraocular tamponade seems to influence the occurrence of retinal dislocation and its direction.

This review aims to give to the reader an overview selectively oriented on safety and efficacy of surgery, providing concise and direct answers about crucial questions of trainees and experts. Surgery for idiopathic epiretinal membrane (ERM) is a safe and effective procedure that can achieve long-term stable postoperative visual and anatomical improvement, with an overall low recurrence and complication rate. Young patients, with a short onset of symptoms and with better initial visual acuity achieve higher levels of visual outcome. The preoperative degree of metamorphopsia is the prognostic factor for their postoperative degree. Successful results may be obtained in eyes with specific optical coherence tomography criteria, such as thin ganglion cell layers, thin internal plexiform layer, longer photoreceptors outer segment, regular ellipsoid zone and cone outer segment tips line, and without ectopic inner foveal layer. Internal limiting membrane peeling demonstrates positive anatomical and functional outcomes, but final positions about its safety remain controversial.
