Defining the aetiology of facial pain can be difficult. While acknowledging the principle of 'common things are common', it is prudent to consider all possible causes. We describe a patient with posterior scleritis that presented as facial pain and was cured by oral prednisolone.
AIM: To estimate the predicted prevalence of primary open angle glaucoma (POAG) from the activity of a local ophthalmology department. METHOD: Using clinic audit data, the local incidence and prevalence of POAG in the registered population of two primary care trusts were calculated. RESULTS: The local derived prevalence estimate for POAG was 978 per 100 000 people aged 40-89 years (95% CI 753 to 1272) compared with the expected prevalence from a published model of 1230 people per 100 000 people aged 40-89 years. CONCLUSION: The derived prevalence was not statistically significantly different from that predicted. Based on the published evidence that about half of the POAG cases are undetected, it would have been expected that local audit figures would have yielded figures about 50% lower than the epidemiological model. The main reason for this higher prevalence is thought to be differences in the diagnostic criteria used. This lack of consensus on the case definition for POAG is a deficit, which will hamper future needs assessment.

Ninety-six cases of anterior globe perforation in children less than 16 years old, requiring surgical repair, were reviewed. Seventy-three patients were male and 23 female, with a mean age of 9 years 4 months. Perforation involving just the cornea was associated with a good visual prognosis unless: it involved the visual axis, resulting in corneal scarring and/or significant astigmatism (> 3.0 DS); it involved greater than one-quarter of corneal diameter; or there was non-compliance with spectacles/patching in patients younger than 8 years old. Injuries involving the lens in those younger than 8 years were associated with a far worse prognosis due to the problems of correcting aphakia. Surgical delay and method of injury did not affect prognosis. Some patients fail to re-attend and greater patient/parent education prior to discharge is recommended.
