Full optical correction after cycloplegia in headache

To study the advantages of cycloplegia in the accurate assessment of refractive errors and to evaluate the impact of full optical correction in the course of headache. and methods: A prospective study was carried out in 164 eyes of 82 patients with headache. Corrected visual acuity was 10/10 in all cases. Refraction was measured before and under cycloplegia by cyclopentolate with a CANON R 50 infrared autorefractometer. Full optical cycloplegic correction based on the value of refraction under cycloplegia was prescribed in all cases. Mean follow-up was 10 months. Statistical analyses were used: Student's t test, Pearson coefficient correlation, and Chi2. Under cycloplegia, hypermetropia was significantly the most frequent ametropia (67.1%, p
