Asia University Hospital Eye Center deputy director Lin Chun-ju (林純如), who treated the patient surnamed Chang, said that before the retinal detachment occurred, the patient had 20/25 vision in the left eye and 20/20 vision in the right eye when using glasses or contacts. However, the patient’s long-term use of steroids triggered early cataracts, causing the vision in both eyes to drop to 20/200, Lin said, without specifying the gender of the patient. Because the patient also suffers from allergic conjunctivitis — commonly known as “pink eye,” which occurs when the eye comes into contact with allergens — and was rubbing their eyes too hard, the force applied to right eye caused the retina to detach, Lin said. Momentary pain or irritation around the eyes after using these drugs is normal, she added. The doctor asked parents to remind children with eye allergies not to rub their eyes too hard, especially those taking steroids to treat another condition.
