METHODS： The clinical records of 27 patients （27 eyes） with culture-proven EFE resulting from fungal keratitis treated at Shandong Eye Institute from January 2007 to January 2015 were retrospectively reviewed. Information about fungal culture results, clinical features, surgical procedures, and final visual acuity was obtained. RESULTS： There were 39 positive culture results from samples of cornea, hypopyon, vitreous and lens capsule, accounting for 56%, 26%, 15% and 2.5%, respectively. Fusarium was identified in 44% （12/27） of the eyes, followed by Aspergillus in 22% （6/27）. Posterior segment infection was involved in 78% （21127） of the patients. The corneal infection was larger than 3 mmx3 mm in 89% （24/ 27） of the patients, and 22% （6/27） of them had the entire cornea, and even the sclera involved. Three eyes had silicone oil tamponade, and two eyes had retinal detachment. Twenty-two eyes （81.5%） underwent penetrating keratoplasty （PKP）, and over half of them （545%） were operated within 3d from the onset of antifungal therapy. Fourteen eyes （52%） underwent intracameral antifungal drug injection, and three of them required repeated injections. Fifteen eyes （55.6%） underwent pars plana vitrectomy （PPV）. The rate of the eyes undergoing PPV as the initial surgical procedure was 60% （9/15）, lower than 77% in PKP. Intravitreal injection was given in 59% of the eyes （16/27）, and 75% of them required repeated injections. The final visual acuity was 20/100 or better in 37% of the eyes, and better than counting fingers in 55.6% of the eyes. Five eyes （18.5%） were eviscerated. In the two eyes with concurrent retinal detachment, one achieved retinal reattachment, and the other was eviscerated. In the three eyes with silicone oil tamponade, two eyes received silicone oil removal, and the other one was eviscerated. CONCLUSION： Fusarium and Aspergillus are the dominant pathogens in EFE resulting from keratitis. Aggressive antifungal surgeries including multiple intravitreal injections, PKP and core vitrectomy （especially in the initial surgery） are helpful procedures to improve prognosis of severe EFE secondary to keratitis.展开更多
