Candidal endophthalmitis after keratoplasty.

PURPOSE

To report a case of explosive fungal endophthalmitis after penetrating keratoplasty and to review additional published and unpublished cases to consider possible strategies for prevention.

METHODS

Records of this patient with postkeratoplasty candidal endophthalmitis and previously reported cases of postkeratoplasty candidal endophthalmitis were reviewed. Additional information of 26 unpublished cases was obtained from the Eye Bank Association of America.

RESULTS

After standard keratoplasty, the patient developed precipitous endophthalmitis on the second postoperative day. Abundant contamination with Candida was found in the residual donor corneoscleral rim, and Candida albicans was isolated from the aqueous humor of the recipient. Despite therapy with local antimicrobial agents, intraocular amphotericin B, and systemic fluconazole, the patient had a poor outcome with hand-motion visual acuity. Of the 44 collected cases of postkeratoplasty candidal endophthalmitis, 40 (91%) had the same organism cultured from the donor rim or medium. Forty-three donor corneas had been preserved in cold storage medium at 4 degrees C. Of 15 cases in which the outcome was available, 9 (60%) resulted in visual acuity of 20/200 or worse.

CONCLUSION

Case reports confirm the occurrence of donor-to-host transmission of postkeratoplasty candidal endophthalmitis. Despite the low reported incidence, the poor prognosis of the affected eye in the ajority of these cases suggests the need for antifungal supplementation of cold preservation media and other preventative strategies.
