A 6 year old child whose initial optometric examination reveals the presence of hyperopia needs further examination through slow dilated pupils. A 6-year-old child whose initial optometric examination reveals the presence of hyperopia during vision screening needs to be further examined with a slow dilated pupil in order to obtain an accurate degree of hyperopia. Hyperopia is one of the more common types of refractive error, with a higher incidence in pediatric patients. If the degree of hyperopia is relatively low, it is usually due to physiologic hyperopia, which is most common in children up to the age of 12 years, whereas a high degree of hyperopia, e.g., greater than 300 diopters, is usually pathologic hyperopia. Since the ciliary muscle inside the eye has a regulating function that can interfere with the results of the optometry, the child’s pupils need to be fully dilated with atropine eye drops or atropine eye ointment during the final optometry examination, i.e., a slow dilation is done to completely paralyze the function of the ciliary muscle in order to get the most accurate degree of hyperopia. If the pupils are dilated by rapid dilation, such as compound tropicamide eye drops, the ciliary muscle cannot be fully paralyzed and the result is inaccurate. It is recommended that the patient go to the ophthalmology department of the hospital in a timely manner, and the doctor will formulate a plan after a comprehensive examination.
