Efectividad en la optimización de la función visual en pacientes con degeneración macular asociada por la edad, retinosis pigmentaria y distrofia de conos y bastones en la clínica de optometría de la Universidad Santo Tomás en el II periodo 2025

Abstract

The objective of this study was to describe the degree of potentiation of visual function through the use of selective absorption filters in patients with age-related macular degeneration, retinitis pigmentosa and rod dystrophy, treated at the optometry clinic of the Universidad Santo Tomás during the second period of 2025. A case series study was developed, framed in the evaluation of evidence-based optometric interventions, considering the low frequency and clinical heterogeneity of these pathologies. The population was mostly made up of women from urban backgrounds and medium socioeconomic levels, without previous use of non-conventional optical aids. The results showed a favorable trend in visual acuity and contrast sensitivity, with variations depending on the pathology and the type of filter used. In patients with age-related macular degeneration and rod and cone dystrophy, improvements in visual acuity and contrast sensitivity were observed, while in retinitis pigmentosa there were no changes in visual acuity, but there were changes in contrast sensitivity. The CPF 450 filter was the most preferred, selected in 75% of the cases, demonstrating potential to optimize visual function and performance in daily activities, thus meeting the objectives set.
