Acanthamoeba Keratitis in an HIV Positive Daily Disposable Contact Lens Wearer

A 43 year old HIV positive myopic man presented with a linear epithelial lesion of his right cornea and a visual acuity of 6/6. A longstanding retinal detachment in the left eye had resulted in a vision of count fingers (CF). Over the next three months, the patient’s visual acuity in his right eye dropped to CF. The case illustrates some typical difficulties involved in diagnosing Acanthamoeba keratitis and demonstrates that therapeutic deep lamellar keratoplasty may be useful as an initial surgical option when medical management fails to control infection.
