background  to report normal variations of the limbal structures using in vivo laser scanning confocal microscopy. methods: this was a retrospective study of fourteen eyes from 11 healthy individuals. confocal imaging of cornea and limbus was performed using heidelberg retina tomograph iii rostock corneal module. results: the typical structure of the palisades of vogt (pov) was detected in 57% ...

PURPOSE To establish the sequence of tomographic changes in the tissue recovery process after pterygium excision and to propose healing indicators. METHODS Optical coherence tomography (OCT) images were taken at 1 week, 1, 3 and 6 months after lesion excision in 73 eyes of 73 patients (33 male, 40 female; mean age 50, S.D. 5.0, range 40-70 years) with primary nasal pterygium. Biomicroscopy wa...

Ocular surface or epibulbar dermoid lesions may present as limbal dermoids at the corneal limbus or dermolipomas in the conjunctival fornix. The purpose of this study is to review clinical features of ocular surface dermoids (grade I), with the visual axis unaffected, in pediatric patients, in order to find key features for making clinical decision, either resection or observation. The study in...

Ocular burns constitute true ocular emergencies and both thermal and chemical burns represent potentially blinding ocular injuries. Thermal burns result from accidents associated with firework explosions, steam, boiling water, or molten metal (commonly aluminium). Chemical burns may be caused by either alkaline or acidic agents. Common alkaline agents include ammonium hydroxide used in fertilis...

Corneal epithelium is a self-renewing tissue. Recent studies indicate that corneal epithelial stem cells reside preferentially in the basal layer of peripheral cornea in the limbal zone, rather than uniformly in the entire corneal epithelium. This idea is supported by a unique limbal/corneal expression pattern of the K3 keratin marker for corneal-type differentiation; the preferential distribut...

PURPOSE To study the short-term clinical results of transplanting of cultivated corneal/limbal epithelial cells on human amniotic membrane (AM) for limbal deficiency. DESIGN Noncomparative, retrospective interventional case series. PARTICIPANTS Thirteen eyes of 13 patients with severe limbal deficiency (Stevens-Johnson syndrome in eight eyes, ocular cicatricial pemphigoid in three eyes, and...

A 6-year-old boy was referred to our hospital with symblepharon and lateral canthal deformity in both eyes, which developed 6 years ago. The patient was born at 27 weeks gestation. He had received cryotherapy for retinopathy of prematurity. One month after cryotherapy, he developed a conjunctival scar with symblepharon in both eyes and underwent symblepharon lysis at another hospital 5 years pr...
