PURPOSE Androgens exert a significant influence on the structure, function and/or pathophysiology of the meibomian gland and conjunctiva. We sought to determine whether this hormone action involves the regulation of epithelial cell gene expression in these tissues. METHODS Immortalized human meibomian gland and conjunctival epithelial cells were treated with placebo or dihydrotestosterone (DH...
A clinical utility assessment of the automatic measurement method of the quality of Meibomian glands
BACKGROUND Meibomian gland dysfunction (MGD) is one of the most common diseases observed in clinics and is the leading cause of evaporative dry eye. Today, diagnostics of MGD is not fully automatic yet and is based on a qualitative assessment made by an ophthalmologist. Therefore, an automatic analysis method was developed to assess MGD quantiatively. MATERIALS The analysis made use of 228 im...
PURPOSE The aim of this study was to investigate the association between tear film and meibomian gland parameters in patients with normal tension glaucoma (NTG), who underwent topical prostaglandin analog (PGA) monotherapy, and medication compliance. METHODS Ocular surface disease index (OSDI), Schirmer's test, tear film break-up time (TBUT), keratoepitheliopathy (KEP) score with fluorescein,...
purpose : to report a case of bilateral dense ring-shaped marginal keratitis after photorefractive keratectomy (prk) case report : a 44-year-old man developed bilateral dense ring-shaped marginal keratitis after prk. the patient had moderate to severe meibomian gland dysfunction preoperatively that was treated incompletely. he was treated with mild topical antibiotics, topical and systemic ster...
Meibomian gland dysfunction (MGD) is the major cause of evaporative dry eye disease (EDED) and dysfunction is widely thought to mechanistically involve ductal hyperkeratinization, plugging and obstruction. This review re-evaluates the role of hyperkeratinization in MGD based on more recent findings from mouse models. In these studies, eyelids from normal young and old mice or mice exposed to de...
OBJECTIVE To identify age-related changes in human meibomian glands that may be associated with meibomian gland dysfunction (MGD). METHODS Excess eyelid tissue from 36 patients (age range, 18-95 years, 19 female, 17 male) who underwent canthoplasty procedures were used. Dermatologic history, age, and presence of MGD were recorded. Samples were frozen, sectioned, and stained with specific anti...
OBJECTIVE To develop a classification system for blepharitis and dry eye based on a classification-tree model of a large group of subjects who were given a variety of objective physiologic tests. METHODS We evaluated 513 subjects, some healthy and some with blepharitis and dry eye,with tests for tear volume, tear flow, and tear turnover and the Schirmer test for dry eye. Meibomian gland funct...
background: intracranial lesions of the pituitary gland are common pituitary adenomas, accounting for 6-10% of all symptomatic intracranial tumors. in this retrospective study, the clinicopathologic features and survival rate of pituitary adenomas were evaluated. methods: the present retrospective study was conducted on 83 patients with pituitary adenomas, referring to radiation oncology depart...
