چکیده

METHODS. Experimental dry eye was created by subjecting C57BL/6 and IFN-knockout mice to desiccating environmental stress for 5 or 10 days. T-cell antigens and IFNwere detected by immunohistochemistry. Goblet cells were counted in periodic acid Schiff (PAS)–stained sections. Expression of small, proline-rich protein (SPRR)-2 was evaluated by confocal microscopy. Tear IFNwas measured by immunobead assay.

Air Exposure Induced Characteristics of Dry Eye in Conjunctival Tissue Culture

There are several animal models illustrating dry eye pathophysiology. Current study would like to establish an ex vivo tissue culture model for characterizing dry eye. Human conjunctival explants were cultured under airlift or submerged conditions for up to 2 weeks, and only airlifted conjunctival cultures underwent increased epithelial stratification. Starting on day 4, the suprabasal cells di...

Impression conjunctival cytology in sicca syndrome - correlations between clinical and histological findings related to dry eye severity.

Keratoconjunctivitis sicca represents a progressive deterioration of ocular surface produced by a deficient secretion of lachrymal film (quantitative disorder) or excessive tear evaporation (qualitative disorder). The cytological analysis of conjunctival impression in 42 patients with dry eye syndrome established a strong correlation between the clinical grade of severity of disease and the gra...

Interleukin-1β and tumour necrosis factor-α levels in conjunctiva of diabetic patients with symptomatic moderate dry eye: case–control study

OBJECTIVES To compare expression of interleukin (IL)-1β and tumour necrosis factor (TNF)-α in the conjunctiva of diabetic and non-diabetic patients with symptomatic moderate dry eye. SETTING AND PARTICIPANTS Nineteen diabetic patients with dry eye, 15 non-diabetic patients with dry eye and 14 diabetic patients without dry eye were recruited. The relative expression of IL-1β and TNF-α in conju...

Immunopathological findings in conjunctival cells using immunofluorescence staining of impression cytology specimens.

The conventional technique of impression cytology provides a non-invasive method for the evaluation of conjunctival epithelium alterations. Using indirect immunofluorescence procedures two inflammatory markers, class II MHC antigens HLA DR and the receptor to IgE (CD23), were sought in impression cytology specimens obtained from 80 patients. In normal subjects conjunctival epithelial cells did ...

The Application of in vivo laser scanning confocal microscopy as a tool of conjunctival in vivo cytology in the diagnosis of dry eye ocular surface disease

PURPOSE To evaluate the applicability of in vivo laser scanning confocal microscopy as a tool of conjunctival cytology in a prospective case-control study. METHODS Nineteen right eyes of 19 Sjogren's syndrome dry eye patients (19 females; mean age: 55.8±15 years), and 18 right eyes of 18 normal healthy control subjects (12 females and 6 males; mean age: 50.8±14 years) were evaluated in this s...
