A healthy 27-year-old woman with a corneal ulcer underwent fibrin gluing with a bandage contact lens twice, due to an impending perforation. The ulcer lesion slowly progressed, unresponsive to topical antibiotics and amphotericin B. We removed the gluing patch and performed a corneal or scraping or biopsy with multiple amniotic membrane grafts to seal the thinned or perforated cornea. Three days after the surgery, the corneal cultures grew Fusarium, as well as Enterococcus faecalis. Three weeks after surgery, the outermost layer of amniotic membranes, serving as a temporary patch, was removed. The anterior chamber was clear without cells. The signs of infection clinically and symptomatically cleared up four weeks later. Two months after surgery, the lesion became enhanced by amniotic membranes. The use of fibrin glue in infectious keratitis should be avoided, because it not only masks the underlying lesion, but it also interferes with drug penetration into the underlying lesion.

A 64-year-old woman was referred to our clinic for the treatment of chronic uveitis in her left eye, which had started two weeks after an uncomplicated cataract extraction. She was treated with topical steroids with an initially good response, yet she subsequently developed severe inflammation and plaque-like material around the intraocular lens, despite continuous steroid therapy. She underwent pars plana vitrectomy, smear and culture of the aqueous and vitreous fluids, and intravitreal antibiotic injection under the impression of Propionibacterium acne (P. acne) endophthalmitis. As a result of the smear and culture of the vitreous fluid identified as an Acremonium species, she was treated with intravenous amphotericin B injections for five days, followed by oral voriconazole administration. During the post-operative 18-month follow-up, she was stable without significant relapse of uveitis. In this case, the best correction of visual acuity was an improvement from 20/40 to 20/20.

A 63-year-old female with candidemia following necrotizing pancreatitis developed clinical signs of chorioretinitis and underwent the systemic administration of voriconazole, after which anterior chamber inflammation and multiple, white, fluffy, chorioretinal lesions, under 1mm in diameter, were gradually resolved and visual acuity improved. We report the first Korean case of candida chorioretinitis successfully treated with the systemic administration of voriconazole.

BACKGROUNDPediatric infectious endophthalmitis is a serious sight-threatening disease for children. The purpose of this study was to investigate the etiology, microbiological spectrum, and visual outcomes of infectious endophthalmitis in children at a single institution in China.

METHODSIt is a retrospective study of the medical records of all patients under 14 years of age with histories of infectious endophthalmitis, treated at a single institution from January 1, 2009 to January 1, 2015. The clinical characteristics, etiology, microbiological spectrum, and management, as well as the visual outcomes, were analyzed. The Kappa test and Chi-square test were used in the statistical evaluation.

RESULTSA total of 271 children were identified, with a mean age of 5.61 ± 2.93 years (range 5 months to 14 years). Ocular trauma (94.8%) and previous ocular surgery (3.0%) were the most common etiologies. Overall, 147 (54.2%) cases had positive cultures, and 176 organisms were isolated from these patients. A single species was isolated in 120 (81.6%) cases, with multiple organisms in 27 (18.4%) cases, and the most commonly identified organisms were coagulase-negative Staphylococcus and Streptococcus species, comprising 29.5% and 26.8% of the isolates, respectively. Moreover, of 176 isolates, 142 (80.8%) were Gram-positive organisms, 23 (13.0%) were Gram-negative organisms, and 11 (6.2%) were fungi. The final visual outcomes were 20/200 or better in 66 (24.4%) eyes, counting fingers to 20/200 in 34 (12.5%), hand motions in 30 (11.1%), light perception in 33 (12.2%), no light perception in 32 (11.8%), and 9 (3.3%) eyes were enucleated or eviscerated. The visual outcomes were not available in 67 (24.7%) patients.

CONCLUSIONSPenetrating ocular trauma is the most frequent cause of pediatric endophthalmitis in China. Streptococcus and Staphylococcus species are the most commonly identified organisms in exogenous pediatric endophthalmitis whereas Fusarium species are commonly seen in endogenous endophthalmitis. In this research, in spite of aggressive management with antibiotics and vitrectomy, the visual prognosis was found to be generally poor.

We describe two patients with fungal keratitis refractory to standard antifungal therapy whose conditions were managed with voriconazole. The first case is a patient with endophthalmitis and corneal ulcer due to Candida parapsilosis after receiving a corneal transplant. The patient was treated with amphotericin but showed no signs of improvement. Topical voriconazole, oral voriconazole, and intravitreal voriconazole yielded signs of improvement. The second case is a 63-year-old male who underwent a month of empiric treatment with 0.2% topical amphotericin for fungal keratitis but showed no signs of improvement. Treatment was then provided with 1% voriconazole. Both cases showed effective treatment with voriconazole. Voriconazole may be considered as a new method to treat fungal keratitis refractory to standard antifungal therapy.

This study analyzed the recent causes, prognosis, and treatment strategies for fungal endophthalmitis. A retrospective review of patients who were diagnosed with fungal endophthalmitis at our center was conducted. The fungal organisms isolated from each patient and the visual prognosis according to the route of infection and treatment method were analyzed. A total of 40 eyes from 30 patients with fungal endophthalmitis were included in this study. Candida species were the most common causative organisms in 35 of 40 eyes. Endogenous and exogenous endophthalmitis were observed in 33 and 7 eyes, respectively. Pre- and post-treatment best-corrected visual acuity (BCVA) was not significantly different between endogenous endophthalmitis and exogenous endophthalmitis. The 40 eyes were treated using the following modalities: intravitreal antifungal agent injection with intravenous antifungal agent (16 eyes), vitrectomy with intravenous antifungal agent (14 eyes), intravenous antifungal agent alone (9 eyes), and evisceration (1 eye). Post-treatment BCVA only significantly improved after treatment in the vitrectomy group. Candida species were the most common cause of fungal endophthalmitis, irrespective of the route of infection. The visual prognosis of fungal endophthalmitis was generally poor. In conclusion, if the general condition of the patient tolerates a surgical procedure, prompt vitrectomy and intravitreal injection of antifungal agents can improve visual acuity.

A 59-year-old woman was referred to our clinic with sudden visual loss in her right eye after she was treated with 40 mg/day of oral prednisolone for 2 weeks under the diagnosis of idiopathic optic neuritis. At that time, computerized tomography (CT) of the brain showed no evidence of optic nerve or brain pathology. However, there was progressive diminution of right visual acuity associated with a limitation of adduction and abduction in the right eye. On magnetic resonance imaging and repeated CT, a malignant lesion was suggested, and was confirmed as an Aspergillus fungus colony by histopathologic examination. Postoperatively, she was treated with intravenous administration of amphotericin B for 13 weeks. However, her condition continued to deteriorate. She developed ptosis and total ophthalmoplegia in the right eye and blindness in both eyes. After discharge, she was given itraconazole for 20 weeks. She has shown no recovery of visual acuity or extraocular motion during a two-year follow-up period. The clinical features of our case suggest that early diagnosis in a case of aspergilloma presenting with visual loss is difficult and that a high index of suspicion, repeated radiological examination and adequate biopsy may be required for diagnosis.

A 54-yr-old male, who was treated by chemotherapy for gastric cancer 15 months ago, presented to Yongdong Severance Hospital, Seoul, with complaints of pain in his right eye caused by a foreign body from the ground in the previous week. He had been treated with topical and oral antibacterial in addition to antifungal agents, but did not show significant clinical improvement. After a positive corneal culture with mold, topical amphotericin B was added to the initial regimen. The mold was identified as Scedosporium apiospermum by macroscopic and microscopic morphologies and the nucleotide sequences of a fungal PCR product showing 99% homology with those of S. apiospermum (EF151349). He recovered with good results at 25 days after corneal epithelial debridement. The early diagnosis of S. apiospermum keratitis is very important for proper treatment. It is recommended that molecular diagnostic methods such as fungal PCR and sequencing be done with conventional cultures whenever a fungal infection is suspected.
