Significance: Dry eye disease is frequently underdiagnosed in pediatric patients. Meibomian gland morphology abnormalities (atrophy and tortuosity) may be associated with dry eye. This study examined risk factors for gland morphology abnormalities in children.
Purpose: This study aimed to characterize meibomian gland morphological abnormalities (atrophy and tortuosity) and identify risk factors for the same in children.
Methods: A total of 160 children, primarily African American and Hispanic, aged 5 to <18 years underwent a comprehensive eye exam including slit-lamp examination to evaluate the meibomian glands, conjunctival papillae, and tear film. Infrared photography was performed including assessment of noninvasive tear film breakup time and tear meniscus height. Meibomian gland atrophy and tortuosity were assessed. A modified Ocular Surface Disease Index survey was administered along with surveys on screen time, diet, and outdoor activity. Linear multiple regression was performed to determine risk factors for meibomian gland abnormalities.
Results: The average age of participants (76 male, 84 female) was 10.9 ± 3.0 years. Severe meibomian gland atrophy (score ≥2) was found in 31.0% of participants in at least one eyelid. Severe meibomian gland tortuosity (score ≥2) was found in 84.0% of participants in at least one eyelid. The median symptom score was 9.8 (range, 0 to 71), with 16.9, 8.8, and 12.5% of the children having mild, moderate, and severe dry eye symptoms, respectively. Elevated body mass index (p<0.001), reduced outdoor activity (p=0.02), and unhealthy diet (p=0.01) were found to be risk factors for meibomian gland abnormalities. Screen time, symptom score, age, gender, and race/ethnicity were not associated with gland abnormalities (all p values >0.05).
Conclusions: This study determined that meibomian gland morphological abnormalities were commonly found in children aged 5 to <18 years. Risk factors for these abnormalities include elevated body mass index, an unhealthy diet, and reduced outdoor activity.

Objective: To determine the state of ocular surface and tear film in college students who are users of inhalants, mainly vapers.
Methods: We conducted a descriptive, observational, and cross-sectional study with 62 participants whose sociodemographic characteristics, ocular surface status, tear film and variables related to vaping were evaluated. Individuals with a higher (5-7 times per week of consumption) and lower frequency of vaping (1-4 times per week of consumption) were evaluated.
Meibum - a lipid-rich secretion produced by holocrine Meibomian glands (MG) - plays a central role in maintaining ocular surface homeostasis. Previously, changes in MG lipidomes induced by inactivation of critical genes of meibogenesis, such as and others, were shown to cause MG-dysfunction- and dry eye-like signs in mice. Here, we describe the impact of the lipid composition of meibum on its physiological properties, specifically thermotropic/melting characteristics, using various wild type and mutant animals, and compare them with meibum of healthy humans and patients with abnormal meibum.

Objective: To explore alterations in tears and ocular surface throughout Descemet's Membrane Endothelial Keratoplasty (DMEK), thereby offering valuable insights for clinical intervention.
Methods: This study was conducted on 84 patients (84 eyes) with CED and received DMEK who visited the Zhongshan Ophthalmic Center of Sun Yat-sen University from April 2022 to January 2024. All patients were evaluated preoperatively and 1, 3, 6, and 12 months postoperatively, with 31 patients (31 eyes) post-24 months above.

Background: Dry eye disease (DED) represents a multifactorial condition characterized by ocular discomfort and visual disturbances. The management of DED relies heavily on accurate diagnosis to tailor effective treatments. Diagnostic approaches encompass both subjective and objective assessments.

Purpose: Sex hormone changes, often occurring during menopause, are implicated in meibomian gland dysfunction (MGD) and evaporative dry eye disease (DED). This study aimed to evaluate whether menopausal status affects the treatment outcomes of perfluorohexyloctane eye drops.
Methods: This post hoc analysis used data from a phase 3 trial (NCT05515471) of perfluorohexyloctane eye drops in patients with DED associated with MGD.
