Are Periocular and Systemic Allergy Conditions Risk Factors for Pterygium?

PURPOSE: To evaluate risk factors for pterygium and prevalence of periocular and systemic diseases among patients with pterygium. METHODS: A retrospective case-control study was conducted among members of Clalit Health Services (CHS) in Israel, from 2001 to 2022. A total of 13,944 patients diagnosed with pterygium were included. For each case, three controls were matched among all CHS patients according to year of birth, sex, and ethnicity. Mixed models were used to assess differences in demographic characteristics, ocular and systemic diseases between the groups. Generalized estimating equation (GEE) logistic regression was used to estimate the odds ratios (OR) and adjust for confounders. RESULTS: The average age of pterygium patients was 49 ± 17 years; 51% were male. The results showed significant associations between pterygium and risk factors of vernal kerato-conjunctivitis (OR 2.52, 95% confidence interval [CI]: [1.96-3.24]), chronic allergic conjunctivitis (OR 1.98, 95% CI: [1.65-2.39]), blepharitis (OR 1.91, 95% CI: [1.78-2.04]), chalazion (OR 1.47, 95% CI: [1.30-1.67]) and unspecified systemic allergy (OR 1.21, 95% CI [1.09-1.34]), after adjusting for rural residency status. Glaucoma (OR 0.74, 95% CI [0.64-0.85]) and smoking (OR 0.70, 95% CI [0.66-0.75]) were protective factors against pterygium. CONCLUSION: Systemic and periocular inflammatory and allergic diseases are risk factors for pterygium.

Pediatricians' knowledge, attitude and practice on treating children with red eye disease.

BACKGROUND: Pediatricians play an important role in the early detection and prompt treatment of ocular disorders in children, including red eye disease. Our aim was to examine the knowledge level of pediatricians regarding treating children with red eye disease, as well as the factors that affect the knowledge level, and the potential implications of a low level of knowledge. METHODS: In this correlational quantitative study, 152 expert pediatricians completed a questionnaire that included questions on knowledge, attitudes, and experience in treating red eye disease. RESULTS: Respondents' mean level of knowledge was moderate. Most of the respondents (89.5%) knew that the most likely diagnosis for a child with red eyes and a discharge is viral conjunctivitis and that pain, blurred vision, and a clouded cornea, are symptoms indicative of a more complex systemic problem. In contrast, 78.3% of the pediatricians claimed that the treatment of choice for viral conjunctivitis is a conservative treatment that includes eye flushing and strict hygiene. However, 14.5% (n = 22) of the pediatricians were found to prescribe antibiotics. A negative association was found between the pediatrician's age and years of experience, and level of knowledge concerning treatment of children with red eye. A strong positive association was found between pediatricians' level of knowledge and their attitudes to performing eye tests. Moreover, a negative association was found between the level of knowledge and the number of cases in which pediatricians prescribed antibiotics for children with red eye. CONCLUSIONS: The research findings indicate that lack of knowledge was more conspicuous among pediatricians with more experience. Knowledge appears to be critical both for readiness to treat red eye and for proper treatment. It is necessary to provide pediatricians with tools for treating eye disorders in children and to refresh their knowledge on red eye, particularly among pediatricians with more years of experience.
