In order to better assist doctors in the diagnosis of dry eye and improve the ability of ophthalmologists to recognize the condition of meibomian gland, a meibomian gland image segmentation and enhancement method based on Mobile-U-Net network was proposed. Firstly, Mobile-Net is used as the coding part of U-Net for down sampling, and then features are extracted and fused with the features in decoder to guide image segmentation. Secondly, the segmentation of meibomian gland region is enhanced to assist doctors to judge the condition. Thirdly, a large number of meibomian gland images are collected to train and verify the semantic segmentation network, and the clarity evaluation index is used to verify the meibomian gland enhancement effect. The experimental results show that the similarity coefficient of the proposed method is stable at 92.71%, and the image clarity index is better than the similar dry eye detection instruments on the market.

Purpose: To compare structural and functional measures of meibomian gland dysfunction (MGD) in eyes with moderate to severe Demodex blepharitis (collarette grade 2-4) compared to those with collarette grade 0 (0-2 collarettes).
Setting: Private clinical practice.
Design: Retrospective, single-center, non-interventional, observational study.

Ethnopharmacological Relevance: Pseudostellaria heterophylla (Tài Zǐ Shēn, TZS) is a traditional Chinese medicine with spleen and qi benefits. Its immunomodulatory, anti-fatigue, anti-stress, and lipid metabolism regulation effects have been clinically confirmed, but its role in meibomian gland dysfunction (MGD) is still unclear.
Aim Of The Study: This study aims to investigate the effect and mechanism of action of TZS in treating MGD.

Purpose: To investigate the changes in meibomian gland (MG) structure in allergic conjunctivitis (AC) patients using an intelligent quantitative analysis algorithm and to explore the relationship between these changes and clinical parameters.
Methods: A total of 252 eyes from patients with AC and 200 eyes from normal controls were examined. Infrared meibography was performed using the non-contact mode of the Keratograph 5M.

Background: Epiphora and secondary ocular surface damage are increasingly impairing the quality of life of people, particularly elderly women. We aimed to investigate the changes in tear cytokine and lactoferrin levels in postmenopausal women with primary acquired nasolacrimal duct obstruction (PANDO) complicated with obstructed meibomian gland dysfunction (OMGD) and preliminary explore the pathological mechanisms of OMGD in patients with PANDO.
Methods: The prospective study involved 43 and 41 postmenopausal women with and without PANDO, respectively.
