Prevalence of refractive error and spectacle coverage in schoolchildren in two urban areas of Chile.

Objective: To assess the impact of efforts to reduce visual impairment by detecting and treating refractive errors (REs) among schoolchildren in two urban areas of Chile.

Methods: In 2013, in the communities of Concepción and La Florida, we conducted a multicenter, multistage-sampling, cross-sectional study employing methods used by the Refractive Error Study in Children (RESC) survey. Best-corrected visual acuity was assessed using pinhole, with and without glasses.

[Markers of thrombophilia in patients with retinal vein thrombosis].

Background: Thrombophilia is an alteration of hemostasis that increases the risk to venous or arterial thrombosis. This condition may be the underlying cause of retinal vein thrombosis.

Aim: To study the presence of thrombophilia in patients with retinal vein thrombosis.
