Fuchs' endothelial corneal dystrophy (FECD) is a progressive vision impairing disease caused by thickening of Descemet's membrane and gradual degeneration and loss of corneal endothelial cells. The aim of this study was to identify differentially expressed genes between FECD-affected and unaffected corneal endothelium to gain insight into the pathophysiological mechanisms underlying this disease. Microarray gene expression analysis was performed on total RNA from FECD-affected and unaffected corneal endothelium-Descemet's membrane (CE-DM) specimens using the Illumina HumanHT-12 v4.

Background: Fuchs endothelial corneal dystrophy (FECD) is a progressive and potentially a sight threatening disease, and a common indication for corneal grafting in the elderly. Aberrant thickening of Descemet's membrane, formation of microscopic excrescences (guttae) and gradual loss of corneal endothelial cells are the hallmarks of the disease. The aim of this study was to identify differentially abundant proteins between FECD-affected and unaffected Descemet's membrane.

The authors report a case of nodular scleritis in Sweet's syndrome. The patient was a 40-year-old Malay woman with a history of Sweet's syndrome presented with a 6-day history of a red and painful right eye associated with blurred vision. Clinical examination revealed nodular scleritis of the right eye which was deemed secondary to Sweet's syndrome after investigations for other systemic diseases were negative.

Background: To describe the implementation and assess the efficacy of an ophthalmic nurse practitioner (ONP) emergency eye clinic.

Methods: In a 13-month period, patients were assessed in an ONP emergency eye clinic in a teaching hospital setting. The ONP clinic was run on a defined scope of practice.
