Abstract Details

Purpose:

Pterygium is a common disease of the eye, especially in hot and dry areas near the equator. Pterygium is a fibro vascular tissue overgrowth beyond the corneal limbal. Several factors, including inheritance, environmental factors such as dust, UV rays and allergies have been involved in its creation. The aim of this study was to determine the role of allergic diseases in creating Pterygium. Some strategies can be provided regarding the treatment and prevention of chronicity of Pterygium.

Setting:

Eye clinic of Vali-asr hospital .Birjand ,Iran

Methods:

62 people were studied including 31 patients as intervention group and 31 healthy individuals as control group. Allergy questionnaires were completed by the participants. Then skin prick test was done with extracts of common allergens including allergens for patients and the control group. For every patient, 5 cc venous blood samples were measured by ELISA Shadow igE levels. Data were collected by a checklist designed based on objectives and entered into SPSS16 software after which analysis was performed using and software design goals and 16 SPSS entered by Chi-square test and logistic regression at the level of α = 0.05.

Results:

In intervention group the mean titer of serum Ig E (121.9 + 142.9) was higher than the control group (108.4 + 98.8); however, this difference was not significant. Skin test results showed that 17 people (54.8%) of the intervention group, and 2 people (65%) of controls had at least one type of allergen sensitivity and this difference was significant. Frequency distribution of symptoms associated with allergies including upper and lower respiratory symptoms, eczema, and seasonal allergies was higher in intervention group compared to control group, although not statistically significant.

Conclusions:

The results of this study showed that the sensitivity to allergens in skin test in patients with Pterygium was significantly higher than control group that could be indicative of a link between allergies and Pterygium
