Abstract
MENDEZ SANCHEZ, Teresita de Jesús et al. Effectiveness of Atropine Treatment Versus Occlusions in Patients with Unilateral Moderate Refractive Amblyopia. Rev Cubana Oftalmol [online]. 2023, vol.36, n.2 Epub June 01, 2023. ISSN 1561-3070.
Objective:
To compare the effectiveness of atropine treatment versus ocular occlusion in patients with unilateral moderate refractive amblyopia.
Methods:
A descriptive, longitudinal and prospective study of a series of cases that attended the Pediatric Ophthalmology office of the Ramón Pando Ferrer Cuban Institute of Ophthalmology during the period from September 2019 to September 2021 was carried out. The sample consisted of 44 patients, who were randomly divided into two study groups, 22 cases to the occlusion group and the same number to the atropine group, who met the inclusion criteria. The variables age, gender, refractive defect, best corrected visual acuity, contrast sensitivity and stereopsis were analyzed.
Results:
Hypermetropic astigmatism predominated in both study groups. Average initial best-corrected visual acuity in both groups was 0.4 LogMAR and improved to 0.1 LogMAR at the end of treatment. Average initial contrast sensitivity was 1.48 (±19.75) for the occlusion group and 1.47 (±20.5) for the atropine group, at completion reaching 1.59 (±10.1) and 1.57 (±10.0) in order of mention. Initial stereopsis was subnormal in both groups, at the end of treatment it was normal in 77.3 % occlusion group and 68.2 % atropine group.
Conclusions:
The effectiveness of treatment in patients with unilateral moderate refractive amblyopia with atropine is similar to that achieved with the application of ocular occlusion.
