Cognitive regulation of saccadic velocity by reward prospect.

It is known that expectation of reward speeds up saccades. Past studies have also shown the presence of a saccadic velocity bias in the orbit, resulting from a biomechanical regulation over varying eccentricities. Nevertheless, whether and how reward expectation interacts with the biomechanical regulation of saccadic velocities over varying eccentricities remains unknown.

Outcomes and complications of hydrogel scleral explant removal.

Background And Objective: To report symptoms of extrusion of hydrogel explants after retinal detachment (RD) repair and the outcomes and complications following removal.

Patients And Methods: All 23 patients had previous RD repair by episcleral buckle with hydrogel explant. Signs and symptoms of scleral buckle (SB) extrusion were analyzed.
