Retained interface gentian violet ink in Descemet stripping endothelial keratoplasty.

Purpose: To present a case of a patient who underwent right Descemet stripping endothelial keratoplasty (DSEK) in whom the gentian violet ink used to mark and orient the donor corneal graft had persisted at the host-graft interface.

Methods: A 57-year-old woman with progressive corneal edema from Fuchs endothelial dystrophy in her right eye underwent a combined phacoemulsification/posterior chamber intraocular lens insertion and DSEK. The host endothelium was stripped in a central 9.

Intrastromal injection of antibiotic agent in the management of recalcitrant bacterial keratitis.

Intrastromal injection is a novel method of delivering an antibiotic agent directly to the site of keratitis. Although intrastromal antifungal agents have been used to manage refractory fungal keratitis, the experience with intrastromal antibiotic agents for bacterial keratitis is more limited. We report a case of refractory bacterial keratitis treated with an intrastromal antibiotic agent and discuss the potential for the clinical use of this modality.

Tight orbit syndrome: a previously unrecognized cause of open-angle glaucoma.

Purpose: To describe a new syndrome of tight orbit and intractable glaucoma with a poor visual prognosis.

Methods: A retrospective observational case series of six patients seen at two centres between 2001 and 2007 assessing intraocular pressure (IOP), best-corrected visual acuity and visual field.

Results: Three men and three women, ranging in age at diagnosis from 14 to 53 years, demonstrated similar orbital features and progressive visual field loss despite intensive management with medication and laser and operative surgery.

Self-tonometry in glaucoma management--past, present and future.

Glaucoma is the leading cause of irreversible blindness in the world. Diagnosis and management of glaucoma is significantly associated with intraocular pressure, but contemporary office-based measurements are not sufficient to discover diurnal changes and spikes, nor do they demonstrate the effect of medication and compliance. Patient-directed self-tonometry can be taken throughout the day and is therefore the subject of much discussion and research.

Histopathology of a functioning mitomycin-C trabeculectomy.

The ideal trabeculectomy bleb is diffuse, normally vascularized and characterized by microcystic change in the overlying conjunctiva. We compare and contrast the histopathology of a normally functioning mitomycin-C trabeculectomy site obtained from an eye enucleated for iris melanoma with abnormal blebs discussed in the literature. Representative sections of the normally functioning bleb were examined under the light microscope.

Orbital cellulitis as a postoperative complication of sub-Tenon anaesthesia in cataract surgery.

Orbital cellulitis is a rarely reported sight-threatening complication of sub-Tenon anaesthesia. We report a case of orbital cellulitis in a patient who had received sub-Tenon anaesthesia for routine cataract surgery. We discuss the potential under-reporting of complications of sub-Tenon anaesthesia that had a delayed presentation, and the possible association between the use of hyaluronidase in the anaesthetic mixture and orbital cellulitis following sub-Tenon anaesthesia.
