BACKGROUND Using a rat penetrating keratoplasty model, this study aims to explore the inhibitory effect of hachimycin on corneal graft rejection, to provide new basis for its clinical application. MATERIALS AND METHODS Female adult Sprague-Dawley (SD) rats weighing between 220-250 g were used as acceptors and male or female Wistar rats weighing between 220-250 g were used as donors. The rats ...

purpose : to report the complications and acute and chronic managements of a case of corneal bee sting injury and to report the outcome of visual performance case report : a 28-year-old caucasian man who was stung by insect and was complaining of ocular pain and decreased vision in the left eye, presented to the emergency room. a sting was found and completely removed. corneal edema, bullous ke...

Bullous Keratopathy, a severe edema of the corneal stroma and epithelium with a characteristic bulla formation on the corneal surface, is a rare opthalmological emergency in cats. Rapidly progressive and uncontrollable by medical means, this condition will result in corneal perforation hours after initial presentation if left unattended. Its pathophysiology and treatment options are reviewed in...

BACKGROUND Visual outcome following repair of post-traumatic corneal perforation may not be optimal due to presence of irregular keratometric astigmatism. We performed a study to evaluate and compare rigid gas permeable contact lens and spectacles in visual rehabilitation following perforating corneal injuries. METHOD Eyes that had undergone repair for corneal perforating injuries with or wit...

CASE REPORT We report one case of Brown-McLean syndrome. DISCUSSION In this case, a 71-year-old male developed a Brown-McLean syndrome after implantation of an anterior chamber lens in one aphakic eye. A phacoemulsification procedure was performed in the other eye without development of corneal clearance alterations in the next 7 years. The cause of Brown-McLean syndrome is still unexplained....

A procedure to determine the best image range of distances that can be obtained from an aphakic eye is presented. Corneal surfaces are calculated from videokeratographic data. Light distributions at different distances inside the eye are calculated with a near-field Fresnel diffraction algorithm. These patterns are evaluated using three different quality functions which quantify the appearance ...

Dtiring the first year of life, diffuse corneal clouding is usually caused by infantile glaucoma or infections and inflammatory processes. Although several of the mucopolysaccharidases may also cause corneal clouding, other signs and symptoms predominate. Maumenee* described a congenital, hereditary corneal dystrophy characterized by diffuse corneal edema during the first year of life. His repo...

A 72-year-old man had exchange of a foldable silicone multifocal intraocular lens (IOL) by transection, removal, and monofocal IOL replacement. One month after the exchange, irreversible corneal edema developed and penetrating keratoplasty was performed. At the time of the corneal transplant, a small silicone fragment was discovered in and removed from the anterior chamber. Histologic evaluatio...

PURPOSE To report a case of herpes simplex virus (HSV) endotheliitis following simultaneous phacoemulsification, intraocular lens (IOL) implantation and descemet's membrane endothelial keratoplasty (DMEK). CASE REPORT A;45 year-old female with corneal endothelial decompensation and a mature cataract, and history of anterior uveitis underwent simultaneous phacoemulsification, IOL implantation ...

A seven-month-old female domestic shorthaired cat was presented for buphthalmos in the right eye and corneal cloudiness in the left eye. Full ophthalmic examinations were performed for both eyes and enucleation was done for the right nonvisual eye. Congenital glaucoma caused by anterior segment dysgenesis was confirmed for the right eye. In the left eye, slit-lamp examination revealed focal cor...
