Abstract Details

Purpose:

To describe clinical findings, causative organisms and visual outcome of microbial keratitis associated with contact lens wear.

Setting:

Department of ophthalmology, Fattouma Bourguiba University of Monastir, Tunisia between January 2006 and December 2014.

Methods:

Retrospective review of the charts of 29 patients (29 eyes) with infectious keratitis associated with contact lens wear. All patients underwent detailed ophthalmic examination. Microscopic examination and culture of corneal scrapes, were performed in all patients. The contact lens and contact lens case were also examined, when available. Mean follow-up was 2.4 months (range: 1-12 months).

Results:

Mean age of our patients was 27 years. Twenty-three patients (97.3%) were female and 6 patients (20.7%) were male. Twenty-seven (93.1%) patients were soft contact lens wearers. Mean initial visual acuity (VA) was 20/800. Stromal infiltrates were associated with ulcers in all cases, and were located in central cornea in 21 cases (72.4%). Hypopion was noted in 10 cases (34.5%). Microbial cultures were positive in 18 patients (72.4%). Pseudomonas aeruginosa was isolated in 41.4% of cases. Amoebic cysts were found in 5 cases (17.3%). Fusarium was isolated in one eye (3.5%). Antimicrobial treatment was based on the suspected or isolated causative agent. Final VA was 20/125.

Conclusions:

Microbial keratitis associated with contact lens wear, is a serious and increasing complication. Pseudomonas aeruginosa is the most common causative germ. Visual outcome is poor. Prevention and prompt management are mandatory to improve visual prognosis.
