Presumed microbial keratitis in the absence of a specific microbiological diagnosis is a particularly difficult clinical problem. Corneal biopsy may provide the diagnosis when corneal scrapings have been negative. We present two cases in which corneal biopsy was helpful and discuss the role of corneal biopsy in the management of chronic keratitis
Refractive keratoplasty using modified relaxing incisions with compression sutures was performed on 33 patients with high post-keratoplasty astigmatism. The mean reduction in keratometric astigmatism was 8.38 dioptres from a preoperative mean of 12.21 dioptres (SD, 3.59) to 3.93 dioptres (SD, 2.13). All patients noted a marked functional improvement. Two patients required reoperation. One patient required resuturing. Our modification of undercutting the relaxing incisions greatly increases the range of astigmatism that can be treated with this technique.
This paper describes two cases of expulsive choroidal haemorrhage (ECH) where the final corrected visual acuity was 6/5. The management of one case consisted simply of vitrectomy; and the other of suprachoroidal drainage of blood followed by vitrectomy. The pathological findings in a series of eyes enucleated following ECH are also described. The literature is reviewed with regard to the aetiology, pathology and management of ECH.
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.
