Article Abstract
The ocular surface flora perform an important role in the defense mechanisms of the ocular surface system. Its regulation of the immunological activity and the barrier effect against pathogen invasion are remarkable. Composition of the flora differs according to the methods of investigation, because the microbiome, composed of the genetic material of bacteria, fungi, viruses, protozoa, and eukaryotes on the ocular surface, differs from the microbiota, which are the community of microorganisms that colonize the ocular surface. The observed composition of the ocular surface flora depends on harvesting and examining methods, whether with traditional culture or with more refined genetic analysis based on rRNA and DNA sequencing. Environment, diet, sex, and age influence the microbial flora composition, thus complicating the analysis of the baseline status. Moreover, potentially pathogenic organisms can affect its composition, as do various disorders, including chronic inflammation, and therapies applied to the ocular surface. A better understanding of the composition and function of microbial communities at the ocular surface could bring new insights and clarify the epidemiology and pathology of ocular surface dynamics in health and disease. The purpose of this review is to provide an up-to-date overview of knowledge about this topic.

Association of Dry Eye and Corneal Ulcers With Collagen Vascular Diseases in a Medicare Population.
Cornea
September 2025
Icahn School of Medicine at Mount Sinai, Department of Ophthalmology, New York, NY.
Purpose: There is a lack of research on the extent to which non-Sjögren collagen vascular diseases affect the ocular surface. This study aims to understand the associations between collagen vascular diseases and dry eye and corneal ulcers.
Methods: This study analyzed a random 5% sample of national Medicare beneficiaries from 2011 to 2015 and included claims for those with collagen vascular diseases and either dry eye or corneal ulcers (n = 2,688,114).
Altered Corneal T-Cell Motility and Sensory Nerve Features in Older Adults With Human Immunodeficiency Virus Infection.
Invest Ophthalmol Vis Sci
September 2025
Department of Optometry and Vision Sciences, The University of Melbourne, Melbourne, Australia.
Purpose: To characterize corneal immune cell morphodynamics and nerve features, and define the in vivo immune landscape in older adults with human immunodeficiency virus (HIV) receiving antiretroviral therapy (ART), relative to healthy age-matched adults.
Methods: In this cross-sectional study, 16 HIV-positive individuals receiving ART and 15 age-matched controls underwent ocular surface examinations and functional in vivo confocal microscopy (Fun-IVCM). Time-lapsed videos were created to analyze corneal immune cells (T cells, dendritic cells [DCs], macrophages).

J Ophthalmic Vis Res
August 2025
Ocular Tissue Engineering Research Center, Research Institute for Ophthalmology and Vision Science, Shahid Beheshti University of Medical Sciences, Tehran, Iran.
Purpose: To report a case of eosinophilic granulomatosis with polyangiitis (EGPA) initially presenting as orbital involvement, describe its successful management, and provide a comprehensive literature review.
Case Report: A 33-year-old female patient presented with swelling, redness, tenderness, and a mass under the left upper eyelid for one month. Upper lid eversion showed a multilobulated lesion in the subconjunctival area of the same region.

Methods: A cross-sectional study used convenience sampling via WhatsApp and face-to-face interviews between 4 February and 29 April 2025. Participants completed a demographic form, the Arabic Ocular Surface Disease Index (OSDI), and the Arabic Depression Anxiety Stress Scale-8 (DASS-8).
Orbital Exenteration Trends at a Single Institution From 2011 to 2024.
Ophthalmic Plast Reconstr Surg
September 2025
Department of Ophthalmology, Bascom Palmer Eye Institute.
Purpose: The primary objective was to investigate the trends in orbital exenteration rates at a large tertiary care center, particularly in the context of recent advancements in immunotherapy, targeted agents, and globe-sparing surgical techniques, which have significantly impacted patient management.
Methods: We conducted a retrospective cohort study at the University of Miami. Patients who underwent orbital exenterations from 2011 to 2024 were identified by obtaining surgical coding data via institutional data brokers and validated through a rigorous surgical chart review.
