purpose : to report a case with history of penetrating keratoplasty (pk) for keratoconus that developed acute hydrops in the recipient and donor cornea methods : a 46-year-old man, with history of bilateral keratoconus, who had undergone corneal transplantation in his left eye, presented with complaints of sudden visual reduction, photophobia, redness and pain of the left eye. results : review ...

this study was conducted to define the prevalence and types of corneal astigmatism in relation with corneal optical power, axial length, sex and patient age. 641 cataract patients were included in a descriptive study. complete eye examinations were included in a descriptive study. complete eye examinations were performed. the data were analysed by standard procedures including analysis of varia...

background: to compare the efficacy of subconjunctival administration of bevacizumab and different doses of sunitinib malate in reducing corneal neovascularization (cnv). materials and methods: in this experimental study, central corneal cauterization was created in the right eye of fifty male sprague–dawley rats. on day 1 (1 week after cauterization), rats were randomly assigned into five trea...

introduction: the aim of the present study was to evaluate the effect of photodynamic therapy in the treatment of experimental corneal neovascularization (nv) with benzoporphyrin derivative (bpd). methods: one group was considered as control (n=6 eyes) then, corneal nv was induced in 30 new zealand male rabbits (n=60 eyes) by placing 7.0 silk sutures at midstromal depth approximately1mm from th...

UNLABELLED Corneal ectasia is a progressive, degenerative, and noninflammatory thinning disorder of the cornea. Recently developed corneal reshaping techniques have expanded the treatment armamentarium available to the corneal specialist by offering effective nontransplant options. This review summarizes the current evidence base for corneal collagen crosslinking, topography-guided photorefract...

A lamellar keratoplasty was used to treat corneal sequestrum in four Persian cats (six eyes). Following a superficial keratectomy, lamellar corneal allografts (feline corneal tissue) or heterografts (canine corneal tissue) which had been preserved at -20 degrees C were placed in the recipient cornea. All grafts became optically transparent within 2 months following surgery and no recurrences of...

One among the corneal diseases causing significant visual impairment and blindness is corneal dystrophies, which is a heterogeneous subset of hereditary corneal disorders that are generally bilateral, non-inflammatory and often result in corneal opacities, requiring corneal transplantation [1]. To add to this group and also which is closely related to dystrophy are the degenerative conditions o...

BACKGROUND As shown previously, the submandibular (SM) lymph node (LN) is required for priming the immune response during corneal graft rejection. In this study, we wished to determine whether corneal grafts at "high-risk" of rejection were also protected after selective SM LN removal and if so to investigate whether this improved corneal graft survival was due to induction of specific regulato...
