Better identification of patients at risk for retinal detachment after intraocular foreign body removal would guide management as well as help prevent this complication. We performed a study to identify risk factors for secondary retinal detachment in eyes with retained intraocular foreign bodies. ⋯ Patients at risk for secondary retinal detachment after penetrating ocular injury with retained intraocular foreign body can be identified at the initial examination.

Randomized Controlled Trial Comparative Study Clinical Trial
The Misericordia Health Centre cataract comfort study.
All surgery provokes various degrees of anxiety for patients. The environment leading up to surgery can affect anxiety levels. We performed a prospective randomized study to compare environmental factors around the time of cataract surgery in order to identify interventions that would minimize stress for patients. ⋯ For patients undergoing cataract surgery, efforts should be directed toward reducing anxiety on arrival at the institution, when it is highest, and not just during surgery. Oral sedation and listening to music before surgery appear to be beneficial. Listening to music through headphones during surgery was not found to be advantageous.

Despite the potential for eye injury, most hockey players in the National Hockey League do not use a protective face shield. We examined the effect of a hockey visor and sports goggle on visual function to see whether visual impediment is a substantial factor in the resistance to use of protective eyewear. ⋯ Protective eyewear does not adversely affect Snellen acuity, contrast sensitivity, Ishihara colour vision or foveal threshold. The central 30 degrees field of vision is not affected by the sports goggle and is minimally depressed by the hockey visor. The goggle better preserves the temporal midperipheral field, but, unlike the visor, the goggle caused a monocular nasal lens rim scotoma. Both devices caused a depression of more than 4 dB of the far temporal field beyond 60 degrees (temporal crescent).
