background: human cornea expresses functional fas-ligand capable of killing fas+ activated lymphocytes. fas expression is partly regulated by -670 a/g polymorphism in the promoter region of fas gene. objective: the aim of the present study is to determine the association between fas-670a/g polymorphism and survival of corneal transplantation. methods: in 276 graft recipients who mainly underwen...
BACKGROUND The acute onset of a focal central interface opacity with visual loss following LASIK has not been described in the peer reviewed literature. Non-peer reviewed reports of various inflammatory lesions have been recorded. METHODS We describe three cases in which an acute focal stromal interface opacification was identified within 1 week of laser in situ keratomileusis (LASIK). Each c...
PHOTOGRAPHY WITH INFRA-RED FILM Dekking (1933, 1934) published several photographs of eyes with dense corneal opacities using infra-red film and radiation of a wave-length of about 10,000 A.u. His photographs strikingly demonstrated how infra-red radiation could penetrate a dense corneal opacity, and clearly record the appearance of the iris and pupil, which were invisible by ordinary methods o...
Abstract Background Cataract surgery is traumatic to the corneal epithelium,scarring and opacity commonest cause of blindness. Objective To study epithelial thickness in different conditions using anterior segment optical coherence tomography (AS-OCT). Patients Methods A case-control including 80 eyes divided equally into 4 groups; group 1:controls,group 2:corneal scarring ,group 3:cataract pat...
A 47-year-old man presented at the Ophthalmology Department of Saku City Asama General Hospital complaining of hyperemia and pain after industrial sodium hydroxide (approx. 40% concentration) had entered his left eye. With an epithelial defect of the bulbar and palpebral conjunctiva, ischemia of the inferior third of the limbal conjunctiva, a total corneal epithelial defect and mild corneal str...
PURPOSE This study evaluates the correlation between corneal densitometry and epithelial ingrowth (EI) after laser in situ keratomileusis (LASIK). METHODS Corneal densitometry of 3 patients who developed EI after LASIK was measured with the Oculus Pentacam. Corneal densitometry readings of each patient were obtained preoperatively and postoperatively after ingrowth was discovered. Densitometr...
Fusarium and Aspergillus species of mold are major causes of corneal infections in the United States and worldwide, resulting in severe visual impairment and blindness. As there is evidence for T cell responses to these pathogenic fungi in infected individuals, we examined the role of IL-17A (IL-17) and IFN-γ in murine models of fungal keratitis. We found that C57BL/6 mice given intratracheal o...
PURPOSE Primary corneoscleral cyst is a rare disease occurring in the pediatric age group. We report a case of corneoscleral cyst with visual diminution. METHODS We conducted a case report. RESULTS A 7-year-old girl presented with corneal opacity in the left eye. Examination revealed a corneoscleral cyst. The corneal part of the cyst involved visual axis. Surgical excision with a scleral gr...
BACKGROUND This study aims to present the management and clinical findings of a case of corneal wasp sting and to report the outcome of corneal change and panuveitis after vitrectomy. FINDINGS Clinical findings, anterior segment photographs, corneal endothelial changes, and medical treatment of corneal wasp sting-induced panuveitis are presented. A 95-year-man was stung by a wasp on his left ...
PURPOSE To investigate whether three consanguineous families from the Punjab province of Pakistan, with affected members with recessively inherited congenital cataract microcornea with corneal opacity, are genetically homogeneous. METHODS An ophthalmic examination was performed on each family member to establish the diagnosis. The two largest families were analyzed by homozygosity mapping usi...
