Purpose: This study aimed to demonstrate the effectiveness of Systane iLux, a thermal pulsation device, in patients with MGD, over 12 months post-single treatment.
Methods: This is a post-hoc analysis of a previous prospective, assessor-masked, parallel-group, multicenter study (NCT03956225) that compared the effectiveness and safety of iLux with LipiFlow in subjects with MGD. The original study included subjects with meibomian gland score (MGS) ≤12 in lower eyelids, Impact of Dry Eye on Everyday Life-Symptom Bother (IDEEL-SB) module score >16, and non-invasive tear break-up time (NITBUT) <10 seconds.
Objectives: To assess 1-week and 1-month efficacy of Systane iLux thermal pulsation treatment for meibomian gland dysfunction (MGD).
Methods: This prospective, nonrandomized, open-label, multicenter study enrolled 30 adult patients (60 eyes) who had a Standard Patient Evaluation of Eye Dryness (SPEED) questionnaire score greater than 6 and total meibomian gland secretion (MGS) score equal to or less than 12 in each eye. All participants received thermal pulsation treatment bilaterally.
Significance: Quantifying meibomian gland morphology from meibography images is used for the diagnosis, treatment, and management of meibomian gland dysfunction in clinics. A novel and automated method is described for quantifying meibomian gland morphology from meibography images.
Purpose: Meibomian gland morphological abnormality is a common clinical sign of meibomian gland dysfunction, yet there exist no automated methods that provide standard quantifications of morphological features for individual glands.
Significance: Lipid deficiency due to meibomian gland (MG) dysfunction is believed to account for the vast majority of patients with dry eye compared with aqueous deficiency. Clinicians commonly evaluate MG length to determine a disease, but our research with isotretinoin users suggests that MG contrast is also an important characteristic to consider.
Purpose: This study aimed to determine the sensitivity and specificity of MG contrast for the diagnosis of lipid-deficient dry eye (LDDE).

Purpose: To develop a deep learning approach to digitally segmenting meibomian gland atrophy area and computing percent atrophy in meibography images.
Methods: A total of 706 meibography images with corresponding meiboscores were collected and annotated for each one with eyelid and atrophy regions. The dataset was then divided into the development and evaluation sets.
Purpose: Meibomian gland contrast may be a potential indicator of gland health, especially among isotretinoin users. We aimed to develop a repeatable and reliable method for measuring Meibomian gland contrast from meibography images.
Methods: Lower lid (LL) and upper lid (UL) meibography were captured with the OCULUS Keratograph 5M (OCULUS, Inc) at 2 visits under the following 4 conditions: face centered with room lights on (C), left-turned face (L), right-turned face (R), and face centered with room lights off (CLO).

Purpose: There has been interest in determining whether lid wiper epitheliopathy (LWE) plays a key role in causing ocular discomfort. Conflicting reports have made it difficult to discern whether LWE is more prevalent in certain populations, what characteristics are associated with its severity, and what its role is in symptomology. This cross-sectional study on a large and diverse population attempts to answer these questions.

Methods: Cross-sectional study using medical history and ocular surface examination to evaluate relationships with study outcomes: SMGA, tear lipid layer (TLL) thickness, non-invasive (NITBUT) and fluorescein (FTBUT) tear breakup times, and symptoms using the Standard Patient Evaluation of Eye Dryness (SPEED) questionnaire.
Results: One hundred one participants (101; 202 eyes; Age: mean±SD = 22.

Purpose: To examine the relationships among tear osmolarity, tear film stability, and several measures of dry eye (DE) symptoms in a multivariable analysis.
Methods: A cross-sectional study was conducted with 137 subjects (68 non-contact lens [CL] wearers and 69 soft CL wearers) recruited from a university campus. Tear breakup time (TBUT) was measured noninvasively (NITBUT) and with fluorescein (FTBUT).
Purpose: To investigate the effects of 30 nights of overnight orthokeratology (OOK) on corneal epithelial permeability (Pdc) and corneal biomechanical properties.
Methods: BE Retainer and Paragon CRT lenses were used. Visits were scheduled approximately 4 hours after awakening at baseline and after 1, 5, 10, 14, and 30 days of treatment.
With the introduction of silicone hydrogel (SiHy) lenses over a decade ago, clinicians have seen both improvements and challenges in contact lens (CL) wear. Regardless of lens design or material, the presence of a CL on the ocular surface induces mechanical complications. Although some of these complications have diminished in frequency and severity with newer generations of SiHy lenses, others persist at previously reported levels.

View Article and Find Full Text PDFPurpose: To determine the effects on corneal epithelial permeability and ocular response of 30 nights of continuous wear (CW) of gas permeable (GP) and silicone hydrogel (SiH) contact lenses.
Methods: Ninety-one subjects successfully completed 30 days of CW of either GP (n = 42) or SiH (n = 49) contact lenses. Epithelial permeability (P(dc)) was measured by scanning fluorometer at an afternoon (PM) baseline session and again the next morning (AM).
