1. Restoration of the rabbit corneal surface after total epithelial debridement and complete limbal excision
How is the corneal epithelium restored when all of it plus the limbus have been eliminated? This investigation explored the possibility that this may be achieved through the conjunctival epithelium. The corneal epithelium of the right eye of 12 rabbits (Oryctolagus cuniculus) was totally scraped followed by surgical excision of the limbus plus 1.0-1.5 mm of

2. "Estudo laboratorial da cicatrização de córneas humanas após debridamento epitelial" / Laboratory study of the wound healing response to epithelial scrape injury in the human cornea
Purpose: To examine the early wound healing response to epithelial scrape in human corneas. Methods: Normal corneas had epithelial scrape prior to enucleation. Histology, TUNEL assay, Ki67, SMA and transmission electron microscopy were performed. Results: Epithelial scrape was performed in six corneas from ½ to 65 hours prior to preservation. Keratocyte apo

3. Influencia do uso topico episcleral intra-operatorio de mitomicina C na proliferação e diferenciação de celulas epiteliais da cornea de coelhas
This study was performed to evaluate the influence of 0,02% mitomycin C (MMC), applied on a single dose for 3 minutes, in proliferation and differentiation of the cornea rabbits epithelium cells. During the surgery procedure, MMC or 0,9% physiologic saline solution (SF) was applied and the solution for each animal (both eyes) was performed by raffle. A topic

4. Morphological changes in the human corneal epithelium associated with surgical corneal clouding.
Light microscopy and electron microscopy were used to define morphological changes occurring in human corneal epithelium during surgery. No correlation was established between preoperative medication or peroperative fluids and corneal epithelial clouding. It is suggested that the changes we observed in relation to epithelial clouding were the direct result o

5. Corneal epithelial recovery following photorefractive keratectomy.
AIMS: To further understand the morphological and functional recovery of corneal epithelium following excimer laser photorefractive keratectomy (PRK). METHODS: The right eyes (group 1) of 15 male, New Zealand white rabbits weighing 2-3 kg underwent PRK. The left eye of each rabbit (group 2) underwent simple mechanical de-epithelialisation and were examined a

6. Corneal epithelium following penetrating keratoplasty.
AIMS--This study was designed to observe any changes to the corneal epithelium after penetrating keratoplasty. METHODS--The corneal epithelia of 26 patients were observed by specular microscopy 1 week, 1 month, 3 months, and 6 months following penetrating keratoplasty. RESULTS--After re-epithelialisation was confirmed by biomicroscopy 1 week after surgery, s

7. Epithelial cyst in the anterior chamber after penetrating keratoplasty: a rare complication.
We report the case of a 25-year-old man who had a penetrating keratoplasty for keratoconus. A year and a half after surgery a cyst was noted in the anterior chamber, which was observed to enlarge over six months. Because of anxiety about endothelial touch, it was removed surgically. Histologically the cyst was composed of stratified, non-keratinized squamous

8. Scanning electron microscopic study of Dacron degradation by ocular tissue extracts.
A scanning electron microscopic study showed that the surface of Dacron thread became significantly roughened after treatment with bovine iris-ciliary body extracts. The Dacron-degrading factor in the extract was nondialysable, heat-labile, and active at an acidic pH, suggesting that lysosomal enzymes may be a factor in this phenomenon. Bovine extracts from
