PURPOSE To elucidate factors contributing to corneal complications after vitrectomy in diabetic patients. METHODS The records of a series of 129 diabetic patients (202 eyes) who underwent pars plana vitrectomy performed by a single surgeon between March 1997 and February 1999 were analyzed retrospectively. Logistic regression analysis was performed to determine possible factors contributing t...

The relationship between corneal edema and hydrogel lens oxygen transmissibility was examined for both daily and extended contact lens wear by measuring the corneal swelling response induced by a variety of contact lenses over a 36-hr wearing period. The relationships derived enable average edema levels that occur with daily and extended wear in a population of normal young adults to be predict...

PURPOSE To test our hypothesis about whether there is water migration in the horizontal corneal plane and investigate its developmental mechanism. METHODS A fluorescein solution was intrastromally injected into normal and edematous corneas of rabbits, and the movement of the fluorescein solution was observed and recorded over time. RESULTS In normal corneas, the water flow was characterized...

BACKGROUND Wound healing of the endothelium occurs through cell enlargement and migration. However, the peripheral corneal endothelium may act as a cell resource for the recovery of corneal endothelium in endothelial injury. AIM To investigate the recovery process of corneal endothelial cells (CECs) from corneal endothelial injury. METHODS Three patients with unilateral chemical eye injurie...

We report the case of a 70-year-old female patient who developed corneal edema and iris discoloration following the inadvertent use of 1% methylene blue instead of 0.025% trypan blue to stain the anterior capsule during cataract phacoemulsification surgery. Copious irrigation was performed upon realization of incorrect dye use. Corneal edema and iris discoloration developed during the early pos...

A progressive, apparently inherited corneal dystrophy is described in an inbred line of Manx cats. Initial changes in the cornea are seen at four months of age and characterized by anterior stromal edema. Progressive worsening of the condition produces severe bullous keratopathy with eventual breakdown of both epithelium and stroma. Light microscopic and ultrastructural studies in the advanced ...
