Purpose: To review the role of antigen-presenting cells (APC) in the pathogenesis of ocular surface diseases (OSD).
Methods: A thorough literature search was performed in PubMed database. An additional search was made in Google Scholar to complete the collected items.
Results: APCs have the ability to initiate and direct immune responses and are found in most lymphoid and non-lymphoid tissues. APCs continuously sample their environment, present antigens to T cells and co-ordinate immune tolerance and responses. Many different types of APCs have been described and there is growing evidence that these cells are involved in the pathogenesis of OSD. OSD is a complex term for a myriad of disorders that are often characterized by ocular surface inflammation, tear film instability and impairment of vision.
Conclusions: This review summarizes the current knowledge concerning the immunotopographical distribution of APCs in the normal ocular surface. APCs appear to play a critical role in the pathology of a number of conditions associated with OSD including infectious keratitis, ocular allergy, dry eye disease and pterygium.

Purpose: Blepharitis and lower eyelid ectropion are highly prevalent ocular conditions occurring in 37%-46% and 2-3% of the general adult population, respectively. Blepharitis has multifactorial origins and involves anterior and posterior types of eyelid inflammation. Lower eyelid ectropion results in ocular surface exposure, epiphora and chronic conjunctivitis.

Background: Chronic kidney disease (CKD) is a significant global health issue, often linked to diabetes, hypertension, and glomerulonephritis. However, aggregated statistics can obscure heterogeneity across subtypes, age, gender, and regions. This study aimed to analyze global CKD trends from 1990 to 2021, focusing on age, gender, socio-demographic index (SDI), and regional variations.

Dry eye disease (DED) is one of the most commonly diagnosed eye disorders, with a prevalence ranging from 5 to 50%, depending on the geographic location. DED is a multifactorial disorder of the tears and ocular surface, which results in symptoms of discomfort, visual disturbance, and tear film instability with potential damage to the ocular surface. It is also accompanied by increased osmolarity of the tear film and inflammation of the surface of the eye.
