PURPOSE: This study evaluated relationships between meibomian gland loss (MGL) and age, sex, and dry eye. METHODS: Dry eye and MGL of the lower eyelid was evaluated from 112 randomly selected subjects (66 women; mean age 62.8; SD ±15.7; and age range: 19-89 years) from Horst Riede GmbH, Weinheim, Germany. In addition, subjects were grouped into dry eye and non-dry eye by the Ocular Surface Disease Index (OSDI) score, lid-parallel conjunctival folds and non-invasive break-up time...

Intense pulsed light (IPL) is a broad spectrum incoherent light which is produced by high-output xenon lamp. Since the invention of the first-generation IPL in 1994, IPL technology has been developing rapidly and extensively utilized in multiple fields relevant to dermatology across the world. In 2004, the fourth-generation IPL system was introduced with the optimal pulse technology (OPT) and has soon been used for cosmetic purposes all over the world. In 2002, Dr. Toyos found that the meibomian gland dysfunction (MGD) and dye eye disease (DED)symptoms of the rosacea patients who received IPL treatment have been improving significantly, therefore he started to explore the application of IPL system to treatment of dry eye disease...

Making oneself more beautiful has always been part of humans' civilized life. Accordingly, the side effects of various cosmetic product and cosmetic procedure long exist. The ocular-surface problems induced by cosmetology mainly include cornea and conjunctiva damages, and tear film damages. Specifically, cornea and conjunctiva damage included: (1) physical injury caused by nonstandard operational procedure, (2) toxic and side effect of cosmetic product, and (3) infection induced by using cosmetic contact lenses, while tear film damage included: (1) injury of normal eyelid structure, (2) decrease of tear production from lacrimal gland, and (3) function and morphology injury of meibomian gland...

PURPOSE: An experimental study to demonstrate in animal eyelids that the controlled exposure of excised tarsal plate to ultraviolet-A radiation can induce a rigidification effect due to photochemical crosslinking of the constitutive collagen. METHODS: Excised strips of sheep tarsus were irradiated with ultraviolet-A rays (wavelength 365 nm) at low and high irradiances, in the presence of riboflavin as a photosensitizer, using radiation sources available for corneal collagen crosslinking procedure...

Lipids secreted from the meibomian gland (meibum) form the superficial layer of the tear film and prevent water evaporation from the ocular surface and infection. Here, we identified the fatty acid (FA) elongases responsible for the synthesis of very long-chain FAs (VLCFAs) that constitute the meibum lipids. Elongation of VLCFAs (ELOVL)1 is primarily responsible for the production of saturated VLCFAs, whereas ELOVL1, ELOVL3, and ELOVL4 redundantly participate in the synthesis of monounsaturated VLCFAs. Gene disruption of Elovl1 in mice shortened acyl moieties in the 2 major meibum lipids: cholesteryl esters and wax esters...

PURPOSE: To investigate, using in vivo confocal microscopy (IVCM), the Meibomian gland (MG) features and conjunctival goblet cell density (GCD) in glaucomatous patients controlled with prostaglandin/timolol fixed combinations (PTFCs). METHODS: In this cross-sectional study, sixty Caucasian patients treated with PTFCs, fifteen with latanoprost+timolol (L+T) unfixed combination, and fifteen controls were enrolled. Patients underwent the Ocular Surface Disease Index (OSDI) questionnaire, tear film break-up time (BUT), corneal staining, Schirmer test I (STI), and IVCM of MGs and goblet cells (GCs)...

Purpose: To evaluate the effect of a single vectored thermal pulsation (VTP) treatment in contact lens wearers with meibomian gland dysfunction (MGD) and dry eye symptoms. Methods: The prospective, nonsignificant risk, open-label, randomized, multi-center clinical trial included 55 soft contact lens (SCL) wearers with MGD and evaporative dry eye. Subjects were randomized to the single VTP treatment group or an untreated control. The controls received a crossover VTP treatment at 3 months (crossover treatment group)...

Purpose: The aim of this study was to compare the efficacy of a single bilateral 12-minute vectored thermal pulsation (VTP) procedure versus daily oral doxycycline for 3 months for moderate-to-severe meibomian gland dysfunction (MGD). Methods: This prospective, randomized, parallel-group, single-masked study included 28 subjects who received either a single-dose VTP or 3 months of doxycycline treatment. At baseline and 3 months post treatment, all subjects were evaluated for the following: dry eye symptoms with a standard dry eye questionnaire (the Standard Patient Evaluation for Eye Dryness [SPEED]), meibomian gland (MG) function by counting the number of glands yielding liquid secretion with the MG evaluator (MGE), tear breakup time (TBUT) and corneal and conjunctival staining...

PURPOSE: To evaluate dry eye tests and meibography of patients with pseudophakic bullous keratopathy (PBK). MATERIALS AND METHODS: Thirty-seven patients with PBK were included. The eyes with PBK were compared with the normal pseudophakic fellow eyes. All patients had undergone a detailed ophthalmic examination including corneal and conjunctival fluorescein staining and Oxford scoring, tear film breakup time, Schirmer 1 test, Ocular Surface Disease Index (OSDI) score assessment, lid margin abnormalities, upper and lower eyelid Meibomian gland evaluation using infrared captures of a biomicroscope...

Purpose: Demodex infestations cause blepharitis and are difficult to treat. Recently, a new type of eyelid wipes with terpenoids has been found effective. We aim to evaluate patient satisfaction after short-term use and compare two teaching modalities on the techniques of use. Patients and methods: Eligible participants were taught to use eyelid wipes (Cliradex®) by either live or online video demonstration based on random allocation. Participants used the wipes twice daily for a week...

PURPOSE: To evaluate the effect of lipid- versus sodium hyaluronate-based eye drops on optical quality and ocular surface parameters. METHODS: Sixty eyes of 30 patients with mild-to-moderate dry eye disease were included in a prospective randomized study. Each patient received either lipid- or sodium hyaluronate-based eye drops. Ocular symptom scores, breakup time, Schirmer test, fluorescein staining, noncontact meibography, and aberrometry were evaluated before and after 3 months of therapy...

Purpose: Mutations in the gene encoding Gasdermin A3 (Gsdma3) have been described to cause severe skin phenotypes, including loss of sebaceous glands and alopecia, in mice. We discovered a novel C-terminal mutation in Gsdma3 in a new mouse line and characterized a less frequently reported corneal phenotype, likely caused by degeneration of Meibomian glands of the inner eyelid. Methods: We used histologic methods to evaluate the effects of the C+/H- mutation on sebaceous gland and skin morphology as well as Meibomian glands of the inner eyelid and corneal tissue...

Chronic dry eye is an increasingly prevalent condition worldwide, with resulting loss of visual function and quality of life. Relevant, repeatable, and stable animal models of dry eye are still needed. We have developed an improved surgical mouse model for dry eye based on severe aqueous fluid deficiency, by excising both the exorbital and intraorbital lacrimal glands (ELG and ILG, respectively) of mice. After ELG plus ILG excision, dry eye symptoms were evaluated using fluorescein infiltration observation, tear production measurement, and histological evaluation of ocular surface...

Background/Aims: Establish a reliable rabbit dry eye (DE) model. Methods: An interventional cohort study surgically removing glands contributing to the tear film. Eight rabbits were studied after removal of left lacrimal, Harderian, or both glands. Additional rabbits had Meibomian glands in the left eye thermally obstructed. All were followed for 10 weeks with phenol red thread (PRT) and slit-lamp examination with 2% fluorescein. We assessed corneal sensitivity using a Cochet-Bonnet esthesiometer...

PURPOSE: To analyze diagnostic performance of an ocular surface workup based on automated noninvasive measurements in the diagnosis of meibomian gland dysfunction (MGD). METHODS: Two hundred ninety-eight eyes of 149 patients with MGD and 54 eyes of 27 control patients were analyzed. Ocular Surface Disease Index (OSDI), noninvasive breakup time (BUT), lipid layer thickness, meibomian gland loss, and tear osmolarity were calculated. The correlations among variables in the MGD group were analyzed...
