PURPOSE: Approximately 30% to 50% of contact lens (CL) wearers report dry eye symptoms. Meibomian gland dysfunction has been recognized as a possible cause of CL-related dry eye. This study investigated the influence of CL wear on the meibomian glands using a newly developed meibographic technique.

PARTICIPANTS: Contact lens wearers (n=121; 47 men, 74 women; mean age+/-standard deviation, 31.8+/-8.0 years) and healthy volunteers (n=137; ...

PURPOSE: To evaluate the efficacy and safety of intense pulsed light (IPL) combined with meibomian gland expression (MGX) for treatment of refractory meibomian gland dysfunction (MGD).

METHODS: Ninety eyes of 45 patients were randomly assigned to receive either the combination of IPL and MGX or MGX alone (control). Each eye underwent eight treatment sessions at 3-week intervals. Parameters were evaluated before and during treatment as well as at 3-11 weeks after the last treatment ...

PurposeTo evaluate diagnostic criteria for obstructive meibomian gland dysfunction (MGD) using three parameters (symptom score, lid margin abnormality score, and meibomian gland morphologic change scores) for differentiating obstructive MGD from aqueous deficiency dry eye (ADDE).MethodsTwenty-five eyes of 25 patients (mean age, 66.6 years) diagnosed with obstructive MGD and 15 eyes of 15 patients (mean age, 61.3 years) diagnosed with ADDE were analyzed. Ocular symptoms were scored from 0 ...

We report a rapid liquid chromatography/quadrupole Orbitrap Fourier transform mass spectrometry (LC-FTMS) method for identifying free fatty acids (FAs) and (O-acyl)-ω-hydroxyFAs (OAHFAs) in human meibum without derivatization. Meibum is a lipid-rich secretion and an important component of the tear film lipid layer. FAs are commonly detected by gas chromatography (GC) or GC/MS after methyl ester derivatization. We developed high-throughput lipid profiling using LC-FTMS and lipid ...

ObjectiveTo examine effects of long-term topical anti-glaucoma medications on meibomian gland morphology and function and assess their relationship with slit-lamp findings.MethodsThis was a cross-sectional observational case series of 31 patients with glaucoma (mean age ± standard deviation, 65.0 ± 13.0 years; mean duration of eye drop use, 7.9 ± 6.0 years) treated with topical anti-glaucoma drugs in only one eye for more than 1 year: 13 receiving prostaglandin analogues (PGs) alone, ...

PURPOSE: To compare meibomian gland morphology between children and adults.

DESIGN: Cross-sectional, observational case series.

METHODS: In an institutional setting, healthy pediatric (n = 78, 30 boys, 48 girls; mean age ± standard deviation, 4.1 ± 3.4 years; range 1 month - 12 years) and adult (n = 25, 11 men, 14 women; 31.3 ± 4.8 years; range 24-39 years) volunteers participated in the study. A noninvasive mobile pen-shaped infrared meibography device was used to observe the meibomian ...

PURPOSE: To evaluate the efficacy of intense pulsed light (IPL) therapy combined with meibomian gland expression (MGX) for refractory meibomian gland dysfunction (MGD) in a prospective study conducted at 3 sites in Japan.

METHODS: Patients with refractory obstructive MGD were enrolled and underwent 4 to 8 IPL-MGX treatment sessions at 3-week intervals. Clinical assessment included the Standard Patient Evaluation of Eye Dryness questionnaire; noninvasive breakup time of the tear film and ...

PURPOSE: To compare tear film parameters as well as meibomian gland morphologic features and function among patients with meibomian gland dysfunction (MGD), those with non-Sjögren syndrome aqueous-deficient dry eye (non-SS ADDE), those with non-SS ADDE and MGD, and normal subjects.

DESIGN: Multicenter, cross-sectional, observational case series.

PARTICIPANTS: Forty-one eyes of 41 patients (all women; mean age ± standard deviation, 62.1±9.9 years) with non-SS ADDE, 70 eyes of 70 patients ...

PURPOSE: To evaluate the effects of commercially available eyelid warming devices on ocular temperatures, tear film function, and meibomian glands in normal subjects and patients with meibomian gland dysfunction (MGD).

METHODS: Ten healthy volunteers were enrolled to evaluate the effects of a single warming and of repeated warming for 2 weeks. Ten MGD patients were enrolled for evaluation of repeated warming over 1 month. Two non-wet (Azuki no Chikara, Eye Hot R) and three wet (hot ...

PURPOSE: To evaluate the prevalence and risk factors of and the relationship between meibomian gland dysfunction (MGD) and dry eye (DE) in Japan.

DESIGN: A population-based cross-sectional study.

METHODS: Participants filled in questionnaires regarding ocular symptoms, systemic diseases, and lifestyle factors. Meibomian gland-related parameters and tear film-related parameters were evaluated. Risk factors for MGD and DE were analyzed by using univariate and multivariate logistic ...

PURPOSE: To observe the morphology of the corneal cells and corneal nerve fibers in patients with type IV or V hereditary sensory and autonomic neuropathy (HSAN) by in vivo confocal microscopy and elucidate the mechanism leading to the loss of corneal sensation in this disease.

METHODS: In vivo confocal microscopy was performed on the central cornea of the right eye in 3 patients with HSAN (ages 17, 20, and 32 years), and their corneal morphology was compared with that of 3 healthy ...

PURPOSE: To observe morphologic changes of meibomian glands in patients with and without perennial allergic conjunctivitis (AC) and to assess the relation between morphologic changes of the meibomian glands of both eyelids and tear film parameters.

PURPOSE: To evaluate whether the amount of meibum and its viscosity change after intraductal meibomian gland probing in patients with refractory obstructive meibomian gland dysfunction (o-MGD).

METHODS: Six lid margins of 3 patients with refractory o-MGD underwent intraductal meibomian gland probing. Meibum and the clinical outcome were evaluated before the procedure and at a 1-month postoperative visit. Meibum was quantified with a Meibometer, and its viscosity (Shimazaki grade) was ...
