Hyperopia in schoolchildren: investigating the impact on vision and determining appropriate methods for screening [PDF]

, 2023
Introduction: Hyperopia is associated with reduced vision and educational outcomes in schoolchildren. This study explored the impact of clinically significant hyperopia (≥+2.00 D) on visual function in schoolchildren and compared the ability of different

Hypermetropia, myelinated retinal nerve fiber and amblyopia: Reverse straatsma syndrome

TNOA Journal of Ophthalmic Science and Research, 2022
Myelinated retinal nerve fibers (MRNF) are a common developmental anomaly. MRNF is commonly associated with myopia. The association of MRNF with myopia, amblyopia, and strabismus is well documented. The amblyopia may be refractory to treatment. We report
