PURPOSE: It was hypothesized that tear protein biomarkers could predict the effects of topical steroid treatment and desiccating stress in patients with dry eye disease (DED). To test this concept, a randomized, double-masked, controlled clinical trial with 41 patients was conducted. METHODS: The patients were treated topically with either 0.1% fluorometholone (FML) or polyvinyl alcohol (PA). Tear samples were collected using 1 μl glass capillaries at recruitment into the study and after a 3-week treatment period, both before and after 2 h exposure to desiccating stress, in a controlled environment chamber...

PURPOSE: Dry eye, a common yet underrecognized and evolving field, has few recommended treatment algorithms, mostly based on expert consensus rather than robust research evidence. There are high costs associated with managing dry eye and conducting research to identify effective and safe long-term treatments. To support evidence-based management of dry eye, our purpose was to identify and prioritize important clinical research questions for future clinical research. METHODS: We translated recommendations from the American Academy of Ophthalmology's 2013 Preferred Practice Patterns for dry eye into answerable clinical research questions about treatment effectiveness...

Dry eye disease (DED) is a multifactorial disease that results in symptoms of discomfort, visual disturbance, and damage to the ocular surface. Because chronic inflammation plays an important role in DED, treatment with topical corticosteroids has been demonstrated to ameliorate the signs and symptoms of the disease. Although these agents have proven short-term efficacy, their long-term use may cause intraocular pressure elevation and cataract progression. A carefully review of the different studies shows that differences between corticosteroids may exist regarding the incidence of side effects and evidence of efficacy in DED patients...

Importance: Lissamine green (LG) staining of the conjunctiva is a key biomarker in evaluating ocular surface disease. The disease currently is assessed using relatively coarse subjective scales. Objective assessment would standardize comparisons over time and between clinicians. Objective: To develop a semiautomated, quantitative system to assess lissamine green staining of the bulbar conjunctiva on digital images. Design, Setting, and Participants: Using a standard photography protocol, 35 digital images of the conjunctiva of 11 patients with a diagnosis of dry eye disease based on characteristic signs and symptoms were obtained after topical administration of preservative-free LG, 1%, solution...

Pilocarpine is a prototypical drug used to treat glaucoma and dry mouth and classified as either a full or partial muscarinic agonist. Here, we report several unexpected results pertaining to its interaction with muscarinic M3 receptor (M3R). We found that pilocarpine was 1,000 times less potent in stimulating mouse eye pupil constriction than muscarinic agonists oxotremorin-M (Oxo-M) or carbachol (CCh), even though all three ligands have similar Kd values for M3R. In contrast to CCh or Oxo-M, pilocarpine does not induce Ca2+ mobilization via endogenous M3R in HEK293T or mouse insulinoma MIN6 cells...

REVIEW
Ebtisam Elghblawi
The clinical application of platelet-rich plasma (PRP) is based on the increase in the concentration of growth factors that are released from alpha-granule of the concentrated platelets and in the secretion of proteins which are able to capitalize on the healing process at the cellular level. It has been invented to restore the natural beauty by starting the natural rejuvenation process of the skin and aiming to make it function as a younger one and to keep the skin youthful and maintain it. Besides that, it is also emerged to include hairs as a new injectable procedure to enable stimulating hair growth locally and topically; preventing its fall; improving hair shaft, hair stem, and its caliber; increasing its shine, vitality, and pliability; and declining hair splitting and breakage...

Dry eye syndrome (DES) is a disorder of the eye due to tear deficiency or excessive evaporation that causes damage to the eye and is associated with discomfort and dryness. 11β-Hydroxysteroid dehydrogenase 1 (11β-HSD1) is an enzyme that converts inactive cortisone to active cortisol. Recently, 11β-HSD1 has been expressed in human and rodent eyes and has been recognized as a target of glaucoma. In this study, the therapeutic effects and underlying mechanisms of topical carbenoxolone, an 11β-HSD1 inhibitor, were investigated in benzalkonium chloride (BAC)-treated human conjunctival epithelial cells and a rat DES model...
