Background: The present study survey risk factors of age-related cataract in patients admitted to selective referral centers in Tabriz. Nurses entail a preventive and educative role based on their knowledge and attitude towards the health and illness.

 Materials and methods: This case-control study was carried out using a consecutive sampling. Totally 500 subjects including 250 patients with age-related cataracts and 250 with non age-related cataracts were requested to fill a prepared questionnaire.

Results: Results revealed that occupation is a personal risk factor. Meanwhile, working indoors (OR=1.56), not wearing sunglasses (OR=1.63), diabetes mellitus (OR=2.06), hypertension (OR=2.51), use of aspirin (OR=3.89), tranquilizers (OR=2.96) and corticosteroid (OR=2.01) as well as fatty meal were risk factors. On the other hand, age-related cataract was associated with positive family history, smoking, electric shock and head X-ray.

Conclusion: Determining risk factors of age-related cataract may pave the way to postpone the morbidity of this disease.
