Atypical dendritic keratitis has been described following herpes zoster infection. This is the first reported case of atypical dendritic keratitis following classical varicella infection It also provides the first light and electron microscopic description of the varicella-zoster dendritic corneal lesion. The diagnosis is substantiated by the clinical appearance of the lesion and by the presenc...

BACKGROUND Peters' anomaly (PA) is a rare form of anterior segment dysgenesis characterized by corneal opacity with varied degree of anterior chamber affection with associated defects in the posterior layers of the cornea. CASE PRESENTATION We report the case of a 3-month-old male infant with bilateral corneal opacity since birth who was transferred from the pediatric unit for further ophthal...

PURPOSE To determine the anatomic cleavage plane of the corneal epithelial adhesion complex in eyes with traumatic recurrent corneal erosion (RCE). METHODS A loosened sheet of corneal epithelium was obtained from corneal epithelial wounds in eight patients with traumatic RCE, before each patient underwent phototherapeutic keratectomy. Three control groups were employed in the study, including...

A case of corneal sequestrum in a 9-year-old Shih Tzu is reported. On the ophthalmic examination a brown-pigmented ulcer with mild edema and corneal vascularization was present. The brownish plaque was facing an inferior palpebral tumor. A superficial keratectomy followed by a grid keratotomy and removal of the palpebral mass were performed. Histological findings revealed an inflammatory cell i...

Individual layers of the cornea as well as lung tissues of rabbit were cultured separately in vitro. The endothelial and stromal cells of the cornea maintained their distinctive tissue culture morphology in serial subcultures for a period of over 20 months, and in the case of one endothelial line, even in passages after thatuing from storage at -79° C. These cell lines proved to be very suitabl...

We assessed the maintenance and distribution of epithelial stem/progenitor cells after corneal reconstruction using tissue-engineered oral mucosal cell sheets in a rat model. Oral mucosal biopsy specimens were excised from green fluorescent protein (GFP) rats and enzymatically treated with Dispase II. These cells were cultured on inserts with mitomycin C-treated NIH/3T3 cells, and the resulting...

The permeability of the corneal endothelial layer has an important role in the correct function of the cornea. Since ionic permeability has a fundamental impact on the passive electrical properties of living tissues, here it is hypothesized that impedance methods can be employed for assessing the permeability of the endothelial layer in a minimally invasive fashion. Precisely, the main objectiv...

PURPOSE To evaluate the feasibility of autologous transplantation in a rabbit model of conjunctival epithelial cells cultured on amniotic membrane for ocular surface reconstruction. METHODS Limbal stem cell deficiency was induced in the right eyes of 30 rabbits. This was done by performing a lamellar keratectomy of the entire cornea and a complete removal of the limbus and conjunctiva, extend...

OBJECTIVES To evaluate corneal densitometry and anterior segment parameters of rheumatoid arthritis (RA) patients and compare these results with those of age-matched healthy control subjects. MATERIALS AND METHODS Anterior segment parameters and corneal densitometry of patients with RA and healthy control subjects were assessed by Scheimpflug corneal topography. For densitometry analysis, the...
