INTRODUCTIONCorneal infection is the most common cause of profound ocular morbidity leading to blindness worldwide. Corneal infection in children is difficult to diagnose and treat, as they are unwilling and sometimes unable to cooperate during active management. This study analyses the prevalence, microbiology, demography, therapeutic and visual outcome of infectious microbial keratitis in the paediatric age group seen at a tertiary eye care hospital in south India.
MATERIALS AND METHODSA retrospective review of all cases presenting with keratitis to the ocular microbiology and cornea service at Aravind Eye Hospital, Coimbatore, from February 1997 to January 2004, was done to screen the patients for microbial keratitis. Their records were further analysed for clinical and microbiological details. Cases with culture-proven non-viral keratitis in children RESULTSOf the 310 patients who attended the cornea clinic, 97 (31.2%) patients were confirmed to be positive for microbial keratitis. 54.6% of cases were male. The most common predisposing cause of ulceration was trauma (69%) with organic matter. Pure bacterial cultures were obtained from 64 (65.9%) eyes, whereas pure fungal cultures were obtained from 37 (38.1%) eyes. Four (4.1%) eyes showed mixed growth. CONCLUSIONThe most commonly isolated organism was Pseudomonas aeruginosa. The most common predisposing cause of infectious microbial keratitis was corneal trauma. Early stage of diagnosis and formulation of an uncompromising management protocol can prevent profound visual morbidity.

PURPOSE: To evaluate the factors affecting treatment outcome of graft infection following penetrating keratoplasty (PKP). METHODS: In this retrospective study, 28 patients who underwent PKP between January 2005 and January 2013 and who were diagnosed with graft infection were classified into a treatment success group or a treatment failure group. Demographic and clinical characteristics, as well as the results of the microbiologic investigation, were analyzed and compared. A subsequent binary logistic regression analysis was performed to identify the prognostic factors affecting treatment outcome. RESULTS: Graft infection occurred at a mean of 38.29 +/- 36.16 months (range, 1 to 96 months) after PKP. Seventeen patients developed bacterial keratitis, and 11 patients developed fungal keratitis. Overall, of the 28 patients, nine (32.1%) were classified in the treatment failure group. Multivariate analysis identified pre-existing graft failure (p = 0.019), interval longer than 72 hours between donor death and PKP (p = 0.010), and fungal infection (p = 0.026) as significant risk factors for treatment failure. CONCLUSIONS: Pre-existing graft failure, extended interval between donor death and PKP, and fungal infection were important risk factors for treatment failure of graft infection following PKP.

Phialemonium keratitis is a very rare case and we encountered a case of keratitis caused by Phialemonium obovatum (P. obovatum) after penetrating injury to the cornea. This is the first case report in the existing literature. A 54-year-old male was referred to us after a penetration injury, and prompt primary closure was performed. Two weeks after surgery, an epithelial defect and stromal melting were observed near the laceration site. P. obovatum was identified, and then identified again on repeated cultures. Subsequently, Natacin was administered every two hours. Amniotic membrane transplantation was performed due to a persistent epithelial defect and impending corneal perforation. Three weeks after amniotic membrane transplantation, the epithelial defect had completely healed, but the cornea had turned opaque. Six months after amniotic membrane transplantation, visual acuity was light perception only, and corneal thinning and diffuse corneal opacification remained opaque. Six months after amniotic membrane transplantation, visual acuity was light perception only, and corneal thinning and diffuse corneal opacification remained.

6.A Congruous Superior Quadrantanopsia Following a Junctional Scotoma Induced by Asperogillosis.

A 69-year old man presented to us with decreased vision in his right eye and a relative afferent pupillary defect. Under the presumption that he was suffering from retrobulbar optic neuritis or ischemic optic neuropathy, visual field tests were performed, revealing the presence of a junctional scotoma. Imaging studies revealed tumorous lesions extending from the sphenoid sinus at the right superior orbital fissure, with erosion of the right medial orbital wall and optic canal. Right optic nerve decompression was performed via an endoscopic sphenoidectomy, and histopathologic examination confirmed the presence of aspergillosis. The patient did not receive any postoperative antifungal treatment; however, his vision improved to 20 / 40, and his visual field developed a left congruous superior quadrantanopsia 18 months postoperatively. A junctional scotoma can be caused by aspergillosis, demonstrating the importance of examining the asymptomatic eye when a patient is experiencing a loss of vision in one eye. Furthermore, damage to the distal optic nerve adjacent to the proximal optic chiasm can induce unusual congruous superior quadrantanopsia.

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.
