OS. Examination revealed enlargement of the epithelial defect, with 50% stromal thinning nasally and inferonasally, without an apparent infiltrate (Figure 2). Corneal culture was positive for Corynebacterium pseudodiptheriticum in the enrichment broth only. A course of fortified antibiotic agents did not improve the clinical findings; there was further thinning of the stroma and impending perfo...
In the current study, we conducted a mutation screening of tumor-associated calcium signal transducer 2 (TACSTD2) gene in six consanguineous Iranian families with gelatinous drop-like corneal dystrophy (GDLD), in order to find the causative mutations. Detailed eye examination was performed by ophthalmologist to confirm GDLD in patients. To detect the possible mutations, direct Sanger sequencing...
The purpose of this study was to evaluate the effects of different time combinations of dexamethasoneand acetylcysteine on experimentally induced corneal ulcers in dogs. Experimental corneal wounds werecreated surgically to the anterior one third of the cornea in the center of all eyes of 15 mixed breed dogs. The eyes were divided into five groups according to planned post-operative medications...
purpose: to study the effect of phototherapeutic keratectomy (ptk) in the treatment of various superficial corneal pathologies. methods: we performed a nonrandomized, prospective study on patients who presented with superficial corneal disease and/or poor vision. fifty eyes were included recurrent corneal erosion (rce): 25 eyes, salzmann’s nodular degeneration: 9 eyes, spheroidal degeneration: ...
purpose: congenital corneal leukoma is rare with an incidence of 6/100000 and is one of the most important causes of amblyopia. here we report an unusual case of bilateral congenital elevated corneal leukoma. methods: we encountered a 13-day-old full term male newborn. ocular examination of both eyes revealed central elevated corneal leukomas with a narrow normal lucid interval to limbus. corne...
Report keratoconus in two patients with a long history of wrestling without any risk factor for corneal ectasia and reviewing the possible pathogenesis. To confirm suspicion of keratoconus, corneal topography was performed using scanning slit topography system and Orbscan. In two wrestlers with the complaint of visual loss in their eyes and IOP raising, corneal topography was performed and de...
Background and purpose: Astigmatism is a common optical dysfunction, effective on various visual outcomes and one of the important criteria of refractive surgery. The aim of present study was to evaluate the correlation between refractive, corneal and residual astigmatism in refractive surgery candidates. Materials and methods: In this cross-sectional descriptive, analytical study, 200 patient...
Fungal keratitis is a severe and common ocular infectious disease. The present study evaluated the efficiency of full-thickness conjunctival flap covering surgery with amniotic membrane transplantation (FCCS + AMT) as a transitional surgery for severe fungal keratitis. A total of 17 patients with severe fungal keratitis without corneal perforation underwent FCCS + AMT between January 2010 and D...
PURPOSE To evaluate the effect of the synthetic matrix metalloproteinase inhibitor, Galardin, on proteases produced by Pseudomonas aeruginosa (PA) and on a rabbit model of Pseudomonas keratitis. METHODS Protease activities of culture broths from Pseudomonas strains PA-28 and W-186 were characterized in vitro by gelatin zymography and by digestion of Azocasein in the presence and absence of Ga...
