Awareness About Keratoconus and Its Relation With Eye Rubbing: A Cross-Sectional Study in Medina

Keratoconus is a non-inflammatory, bilateral, asymmetrical progressive disorder characterized by ectasia, thinning, and increased curvature of the cornea, as well as loss of visual acuity. Eye rubbing is considered the most common risk factor for keratoconus.

This study aims to assess the awareness of the population in Medina about keratoconus and its relation to eye rubbing.

This is a cross-sectional study involving 767 participants via an online pre-designed questionnaire from November 2021 to January 2022, in Medina, Saudi Arabia.  Results: Among the study participants, 94.1% have a lack of awareness about keratoconus and its relation to eye rubbing. Participants who have a visual disturbance and positive family history of keratoconus were found to have good awareness levels. Those who heard about keratoconus represent 39.8% of the participants, and relatives with keratoconus were the most common source of their information. An allergic reaction was reported by 34.9% of the participants, and 7.7% have a family history of keratoconus. Only 27.8% believe in the relationship between keratoconus and allergy, and 61.9% have no idea about the treatment. For eye rubbing, 28.9% of participants believe it can lead to keratoconus; also, 80.4% reported rubbing their eyes, and itching was the most common cause of their behavior.

The majority of the participants have a lack of awareness about keratoconus and its relation to eye rubbing. Health education programs for the population should be conducted to enhance public awareness about keratoconus.
