Choroidal detachment more common with large corneal perforations

Choroidal detachment commonly occurs following corneal ulcer perforations, a study found. Because patients with larger perforations are at particular risk, B-scan ultrasonography should be used to detect possible detachments, the authors noted.
Harminder S. Dua, FRCOphth, PhD, and colleagues at the Queens Medical Centre in Nottingham, England, investigated the frequency of choroidal detachments among patients with nontraumatic penetrating corneal ulcers.
The study included 18 eyes of 17 patients. The researchers found that eight eyes (44%) developed choroidal detachments, with six of the eight detachments (75%) occurring in eyes with perforations greater than 2 mm², according to the study. There was no correlation between the duration of perforation and presence of choroidal detachment, the authors noted.
The study is published in the September issue of the British Journal of Ophthalmology.
