Optimal compliance for amblyopia therapy: occlusion with a translucent tape on the lens.

Objective: To demonstrate that optimal compliance to amblyopia therapy and a better visual outcome can be achieved by occluding the lens over the preferred eye with a translucent tape.

Study Design: Prospective study of amblyopic children.

Participants: Eighty-four amblyopic children recruited from 2000 to 2006 at the Montreal Children's Vision Centre.

Resolution of periodic alternating nystagmus after decompression for Chiari malformation.

Case Report: A 20-year-old female presented with horizontal jerk nystagmus, blurred vision, severe headaches, unsteady gait, and paresthesia. Magnetic resonance imaging revealed Chiari malformation I. Symptoms resolved after decompression of the posterior cranial fossa and removal of the right cerebellar tonsil.
