To describe the course and complications of varicella zoster ophthalmicus (VZO) in patients attending an eye clinic in a community with a high HIV seroprevalence. ⋯ In a resource-limited setting, patients with the following characteristics should have immediate ophthalmic assessment: symptoms suggesting ocular complications or the presence of Hutchinson's sign. All VZO patients should receive antiviral therapy at the first doctor's visit even if they present >72 h after onset of the rash.

External allergens are the main causative factor in the pathogenesis of allergic diseases; however, little is known about internal factors such as the biometrical structure of the eye. We investigated the relationship between refractive error and allergic conjunctivitis in order to reveal possible insights into the pathogenesis in 1015 subjects. ⋯ Refractive error may be a risk factor for allergic conjunctivitis.

Multicenter Study
The Cataract National Dataset Electronic Multi-centre Audit of 55,567 operations: anaesthetic techniques and complications.
The primary aim of this study was to detail anaesthetic techniques and complications for cataract surgery in the UK. ⋯ Subtenons anaesthesia was the most widely used anaesthetic technique for cataract surgery but wide variation existed by site. There was a low rate of reported LA complications. There was a statistically significant increased risk of serious complications with sharp needle anaesthesia compared with subtenons technique.

Randomized Controlled Trial
The effect of hyaluronidase on ultrasound-measured dispersal of local anaesthetic following sub-Tenon injection.
To determine by B-scan ultrasonography if the addition of hyaluronidase affects the dispersal of anaesthetic fluid after sub-Tenon's injection. ⋯ The addition of hyaluronidase significantly augments the dispersal of local anaesthetic fluid, as measured by B-scan ultrasonography.
