PURPOSE Amino-amide or amino-ester local anesthetics, which are currently used for topical ocular anesthesia, are short acting and may delay corneal healing with long-term use. In contrast, site 1 sodium channel blockers (S1SCBs) are potent local anesthetics with minimal adverse tissue reaction. In this study, we examined topical local anesthesia with two S1SCBs, tetrodotoxin (TTX) or saxitoxin...
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 examine the efficacy of a novel method of decellularizing porcine corneal stroma using N(2) gas from liquid N(2) and the feasibility of using decellularized porcine corneal stroma in a corneal transplantation model in rabbits. METHODS Porcine corneas were placed in a tube, and N(2) gas from liquid N(2) was poured into the tube to freeze the corneas and make the inside of the tube h...
Acanthamoeba keratitis is increasingly being diagnosed among people who wear thrapeutic and cosmetic contact lenses. The chain of events is thought to begin with contamination of the contact lens storage cases with Acanthamoeba from household or mains water supplies. If bacteria contamination is also present then these amoebas can multiply by ingesting the bacteria as a food source. If the cont...
microbial corneal diseases are a serious ocular infection and the major cause of ocular morbidity and blindness in the world. the outcomes of fungal keratitis are unfavorable due to the protracted course of the condition and the diversity of respective clinical presentations. trauma, contact lens wear, foreign material, and prior corneal surgery, may make the most background for permitting inva...
Various clinical disorders and injuries, such as chemical, thermal, or mechanical injuries, may lead to corneal loss that results in blindness. PURPOSE: The aims of this study were to differentiate human buccal mucosa (BMuc) into corneal epithelial-like cells, to fabricate engineered corneal tissue using buccal mucosal epithelial cells, and to reconstruct a damaged corneal epithelium in a nude ...
background: photorefractive keratectomy is a popular mean to correct refractive errors of the eye and haze formation is one of the most important complications of the surgery. although standard dose of intraoperative mitomycin c has shown to be effective in reduction of this complication, potential side effects of mitomycin c promote us to show if the lower concentration of mitomycin c has t he...
purpose: to report a case of anterior segment eye deposits in a patient on long-term chlorpromazine therapy. case report: a 34 years old man had been on chlorpromazine therapy for 5 years with a total dose of 1,100 gram. since one year ago, he presented with gradual onset of decreased visual acuity in both eyes. slit-lamp examination revealed multiple fine yellow-brown deposits on the corneal e...
purpose: to investigate the incidence, mechanisms, characteristics, and visual outcomes of traumatic wound dehiscence following keratoplasty. methods: medical records of 32 consecutive patients with traumatic globe rupture following keratoplasty who had been treated at our center from 2001 to 2009 were retrospectively reviewed. results: the study population consisted of 32 eyes of 32 patients i...
purpose : to evaluate central corneal thickness (cct) in patients with juvenile glaucoma and compare it with that of normal individuals methods : a prospective, case-control study was performed on 80 eyes with juvenile glaucoma who attended glaucoma clinic in farabi eye hospital, tehran, iran and 107 clinically normal healthy eyes. standard automated perimetry (sap) was performed for all the pa...
