ANALYSIS OF TIME TO FAILURE AFTER RETINAL DETACHMENT SURGERY.

Purpose: To present the distribution of time to retinal redetachment in eyes undergoing retinal detachment surgery, using a method for adjusting time to outcome in eyes with silicone oil or heavy liquid tamponade ("oil-filled eyes").

Methods: Data from two Australian centers were used. Adjusted time to outcome was measured from the date of tamponade removal in oil-filled eyes, unless failure was diagnosed with tamponade in situ.

Unequal pupils: Understanding the eye's aperture.

Background: Unequal pupils (anisocoria) may be physiological, pathological or pharmacological. Importantly, anisocoria can indicate underlying disease of the eye, orbit, brain, neck or chest. Examination of the pupils is therefore a crucial part of any eye examination.
