Corneal ulcers in general practice.

BACKGROUND

Patients frequently present to general practitioners (GPs) with discomfort and a red eye due to corneal ulceration, defined as a defect in the corneal epithelium and underlying stroma. A myriad of conditions may lead to corneal ulcers, and prompt diagnosis and adequate management is needed to prevent visual morbidity.

OBJECTIVE

The aim of this article is to assist clinicians/GPs to 1) determine the likely cause of a corneal ulcer and 2) understand the management of corneal ulcers, including the timing of referral to an ophthalmologist.

DISCUSSION: Corneal ulcers are typically painful and reduce vision. A good understanding of the clinical presentation of corneal ulcers can aid diagnosis and guide treatment. Urgent referral of trauma and infectious keratitis to an ophthalmologist can prevent endophthalmitis and loss of vision and/or the eye. GPs can play an important part in timely referral, in some cases initiating oral antiviral treatment, and by educating patients on preventive measures, especially contact lens hygiene.
