AI Article Synopsis
- The study aimed to analyze the link between inflammatory conditions in the eyes and body and the development of pterygium, a growth on the eye's surface.
- Researchers used electronic medical records from Clalit Health Services in Israel, comparing over 94,000 pterygium patients with nearly 379,000 matched controls based on age, sex, and ethnicity.
- Results showed significant associations between pterygium and several inflammatory conditions, both ocular (like vernal keratoconjunctivitis and blepharitis) and systemic (like asthma and atopic dermatitis), indicating these conditions may increase the risk of developing pterygium.
Article Abstract
Purpose: The purpose of this study was to examine the incidence of ocular, periocular, and systemic inflammatory conditions among patients with pterygium and assess if these conditions are risk factors of pterygium development.
Methods: A case-control study was conducted using electronic medical records from Clalit Health Services in Israel between 2001 and 2022. Patients diagnosed with pterygium were included; for each case, 3 controls were matched based on birth year, sex, and ethnicity. Mixed models were used to assess differences in the groups' demographic characteristics of ocular and systemic diseases. Generalized estimating equation logistic regression was used to estimate the odds ratios (ORs) and adjust for confounders.
Results: A total of 94,652 patients diagnosed with pterygium and 378,608 matched controls were included in the study. The average age of patients with pterygium was 53 ± 16 years; 54% were male. A significant association was found between pterygium and vernal keratoconjunctivitis (OR 2.12, 95% confidence interval [CI], 1.90-2.36), chronic allergic conjunctivitis (OR 1.69, 95% CI 1.58-1.82), blepharitis (OR 1.66, 95% CI 1.61-1.70), and chalazion (OR 1.27, 95% CI 1.23-1.33). A significant association was also found between pterygium and systemic conditions as unspecified systemic allergy (OR 1.08, 95% CI 1.04-1.13), asthma (OR 1.08, 95% CI 1.04-1.11), and atopic dermatitis (OR 1.14, 95% CI 1.08-1.19).
Conclusions: Various inflammatory and allergic diseases-ocular, periocular, and systemic-increase the risk of pterygium. Further research is needed to investigate the role of inflammation in pterygium development.

Background: The ocular surface is directly exposed to environmental influences. Noxae that have already been identified for the ocular surface are heat, air dryness, pollutant gases, fine dust particles and ultraviolet radiation.
Methods: The current literature was used to investigate the relationship between frequent ocular surface diseases and various environmental factors and to analyze their development over the years.

Pterygium is an ocular disease in which the conjunctival tissue invades the cornea. When the pterygium tissue reaches the pupillary region, the visual function of the patient is affected. Currently, surgical removal is the only effective treatment.

Background: Pterygium is a complex ocular surface disease characterized by the abnormal proliferation and growth of conjunctival and fibrovascular tissues at the corneal-scleral margin. Understanding the underlying molecular mechanisms of pterygium is crucial for developing effective diagnostic and therapeutic strategies.
Methods: To elucidate the molecular mechanisms of pterygium, we conducted a differential gene expression analysis between pterygium and normal conjunctival tissues using high-throughput RNA sequencing.

Purpose: To characterize corneal and conjunctival abnormalities (CCAs) and their impact on visual acuity in a cohort of survivors from the Western African Ebola virus disease (EVD) outbreak.
Design: A post hoc analysis of 121 patients, who had previously undergone screening for the Ebola Virus Persistence in Ocular Tissues and Fluids study, was performed.
Methods: Patients underwent a comprehensive ophthalmic exam at the Lowell and Ruth Gess Eye Hospital in Freetown, Sierra Leone.

The ocular safety of 222-nm far-ultraviolet-C (UV-C) irradiation, widely recognized for its germicidal properties, was evaluated in a clinical setting to assess its long-term health effects on the human eye. This prospective observational study involved a 36-month follow-up of physicians working in an ophthalmic examination room equipped with 222-nm UV-C lamps. Initially, a 12-month observation showed no signs of acute or chronic ocular damage.
