We evaluated the levels of lipid oxidative stress markers and inflammatory cells from tears conjunctiva patients with Sjögren syndrome (SS) normal subjects.We examined 31 eyes 16 (16 females) SS 15 10 healthy controls (2 males 8 in this prospective study. All subjects underwent a Schirmer test, measurement tear film break-up time, vital stainings, confocal microscopy conjunctiva, collection for hexanoyl-lysine (HEL), ELISA, conjunctival brush cytology. Brush cytology samples...

Introduction Remote pharmacist interventions have achieved much more attention during the coronavirus disease 2019 (COVID-19) outbreak, since they reduce risk of transmission and can potentially increase access vulnerable populations, such as patients with COVID-19, to pharmaceutical care. This study aimed examine differences in rates types related COVID-19 medication dispensing errors (MDEs) across community pharmacies without telepharmacy services. Methods was a prospective, disguised,...

Purpose.: To demonstrate the conjunctival alterations in patients with Sjögren's (SSDE) and non-Sjögren's syndrome dry eye (NSSDE) using a new generation confocal microscope (HRTII/ RCM; Heidelberg Engineering, Heidelberg, Germany), prospective controlled study. Methods.: Twenty-eight right eyes of 28 SSDE (28 women; mean age, 58.2 ± 14.3 years), 7 NSSDE (7 66.1 14.4 14 age- sex-matched control subjects were studied. All underwent Schirmer test, tear film breakup time (BUT), vital staining,...

Purpose The purpose of our study was to investigate alterations in the meibomian gland (MG) Cu, Zn-Superoxide Dismutase-1 knockout (Sod1−/−) mouse. Methods Tear function tests [Break up time (BUT) and cotton thread] ocular vital staining test were performed on Sod1−/− male mice (n = 24) aged 10 50 weeks, age sex matched wild–type (+/+) 25). serum samples collected at sacrifice for inflammatory cytokine assays. MG specimens underwent Hematoxylin Eosin staining, Mallory fibrosis, Oil Red O...

Background: Telepharmacy services are expected to have an important role in increasing access of patients pharmaceutical care and reducing potential dispensing errors community pharmacies. Objective: To assess the predictors for effective telepharmacy on Method: This is a prospective study carried out 4 months 52 pharmacies across United Arab Emirates (UAE) using disguised direct observation. Multivariable logistic regression was used as tool predict factors associated with improving safety...

Purpose.: To prospectively evaluate the effect of controlled adverse chamber environment (CACE) exposure on tear function, including osmolarity, in subjects wearing narafilcon A versus those etafilcon soft contact lens (SCL). Methods.: Thirty-one healthy with no history wear (13 women, 18 men; average age, 30.5 ± 6.5 years) were randomly divided into age- and sex-matched groups (15 SCL; 16 SCL) entered a CACE for 20 minutes. All underwent evaporation rate, strip meniscometry, film breakup...

Purpose. To investigate the status of oxidative stress and histopathologic alterations in patients with conjunctivochalasis compare findings those healthy control subjects. Methods. Eleven (n = 20 eyes) Yokoi grade 3 11 health subjects 22 were prospectively recruited. ELISA for tear hexanoyl-lysine (HEL) inflammatory cytokines, film break-up time tests, Schirmer test measurements, fluorescein rose bengal vital staining performed. Conjunctival specimens obtained during surgery cataract...

To evaluate the specificity and sensitivity of strip meniscometry (SM) testing in conjunction with tear function tests diagnosis dry eye (DE) disease to investigate effect SM on reflex tearing.One hundred seven left eyes 107 patients definite DE according Japanese diagnostic criteria 68 age- sex-matched control subjects were studied. Tear meniscus height (TMH) measurements, fluorescein film break-up time (FTBUT), (F) rose bengal (RB) staining, Schirmer's test-1 (ST) also performed. The...

Purpose.: To investigate the efficacy of 2% rebamipide ophthalmic solution on tear functions and ocular surface status superoxide dismutase-1(Sod1−/− ) mice. Methods.: Two percent Rebamipide was applied to 40-week-old male Sod1−/− wild-type (WT) mice four times a day for 2 weeks. We examined cytokine concentrations in fluid (by CytoBead assay), film break-up time, amount production, expressions mucins 1, 4, 5AC, by RT-PCR. also performed vital staining surface, PAS muc5AC,...
