Evaluation of functionality in children aged 4-6 years presenting congenital toxoplasmosis and retinochoroiditis

Abstract

Introduction: In Brazil, congenital toxoplasmosis (CT) is the main cause of visual impairment in childhood. It causes retinochoroiditis, which should lead to blindness. Minas Gerais has a prevalence of 1 newborn with congenital toxoplasmosis for every 770 live births. Objective: To evaluate visual functionality and tasks of self-care with TC classified in groups according to a visual acuity. Method: A cross-sectional study with 96 preschoolers with CT. Ophthalmologic examination and assessment of some functionalities were performed: The Functional Vision Evaluation (AVIF-2 at 6 years) and the Pediatric Disability Assessment Inventory (PEDI-Brazilian version). Results: Children were classified into three groups according to visual acuity: moderate / severe visual loss (n=16), low level (n=39) and normal vision (n=41). The chance of difference is not greater than AVIF-2 at 6 years among the three groups (p=0.001), being (p <0.0001) between the groups with moderate/severe visual and normal vision. The domain scores are displayed as the end result (p=0.022). The test PEDI is not able to make a difference between the groups. It is not different between the scores of the tests carried out. Conclusion: Children with CT without moderate / severe visual impairment, compromising visual functionality with greater impairment without visual accompaniment. The AVIF-2 at 6 years test demonstrated the impairment between groups with different visual acuities. The PEDI (self-care) test was not performed with a significant difference in scores between the groups. The AVIF-2 at 6 years test may contribute to the more effective intervention in the visual habilitation of children with CT and low vision.
