The Effect of Hyperthyroidism on Refractive Errors and Visual Acuity

Abstract

Hyperthyroidism is a condition in which there is over production of thyroid hormones, abnormal antibodies that attack the thyroid gland causes it to become over active. Abnormal antibodies may cause swelling and inflammation of the soft tissue around the eyes and the muscles that move the eyes and the eyelids.Aim of the study: The aim of the study was to find the effect of hyperthyroidism on the vision and development of refractive errors in patient with hyperthyroidism Results: It was found that the usual age of onset of hyperthyroidism was between 30 and 50 years with the females’ preponderance. Myopia showed in high percentage within the age 40-50 and >50 years (61.1%), (68.0%) respectively. While hypermetropia was seen more in age <40 (28.9%) and hyperthyroidism has a bad effect on the visual acuity.Conclusion: Myopia was seen more in older age group while hypermetropia seen in younger age group. Hyperthyroidism has a bad effect on the visual acuity.
