Corneal sensation was found to be decreased in eyes affected by acute angle closure glaucoma. In those patients with a short history (less than four days) the difference in sensation between the two eyes was only detectable using the Cochet-Bonnet aesthesiometer and not by using cotton wool. Patients with a longer history had a more marked decrease in corneal sensation that was detectable by both methods. Corneal sensation in both groups tended to recover partially on normalization of the intraocular pressure.
A review of all penetrating eye injuries treated at the Manchester Royal Eye Hospital over 5 years (January 1st 1982 to December 31st 1986) was undertaken. There were 258 penetrating eye injuries of which 69 (26.7%) were due to work-related accidents. All were men and 52 (75.4%) of them were under the age of 40 years. Hammering and chiselling were the commonest activities at the time of the injury and accounted for 25 cases (36.2%). Thirty-six patient (52.1%) had intraocular foreign bodies. Thirty-six patients (52.1%) achieved a good visual result (6/12 or better) and 9 had no perception of light, 7 of whom had enucleations. The period of inpatient treatment ranged from 1 to 26 days. From the analysis of the activities at the time of the injury, 61 injuries (88.4%) may be considered to be preventable with appropriate eye protection.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
