Abstract
Objetivo: Determinar la relación entre la sensibilidad luminosa (SL) macular y los espesores de la retina central en ojos sanos jóvenes y mayores.
Material y métodos: Se realizó un estudio de tipo observacional, transversal y comparativo, en 62 voluntarios sanos divididos en 37 jóvenes de 23,5 (±2,2) años y 25 mayores de 62,2 (±4,4) años. Se midió la SL macular mediante microperimetría (MP) MAIA y los espesores de retina total, externa e interna en el área macular en cinco sectores maculares (central, temporal, nasal, superior e inferior) mediante tomografía de coherencia óptica de dominio espectral (SD-OCT). Se realizó un análisis comparativo entre ambos grupos de edad y un análisis de correlación entre la SL y el espesor retiniano en el área macular.
Resultados: La SL media total (p˂0,0001) y por sectores fue menor en el grupo de mayores en comparación con el grupo de jóvenes. El espesor de retina completa fue mayor (p=0,0017) en el sector central, el de retina externa fue mayor en todos los sectores y el de retina interna fue menor en casi todos sus sectores maculares en los mayores en comparación con el grupo de jóvenes. En el grupo de personas mayores, la SL disminuyó conforme aumentaba el espesor de retina externa en el sector inferior y conforme disminuía el espesor de retina interna en el sector nasal. Para la muestra total, la SL disminuyó conforme aumentaba el espesor de retina completa en el sector central y de retina externa en el sector central, nasal, superior e inferior. En cambio, disminuyó conforme disminuía el espesor de retina interna en el sector temporal, nasal y superior.
Conclusiones: La SL disminuyó según aumentaba el espesor macular de la retina externa y según disminuía el espesor macular de la retina interna en el grupo total y de sujetos mayores.
Purpose: To determine the relationship between the macular light sensitivity (LS) and the thicknesses of the central retina in both healthy young and old eyes. Material and method: An observational, transversal and comparative study was carried out in 62 healthy volunteers divided into 37 young people of 23,5 (±2,2) years old and 25 old people of 62,2 (±4,4) years old. The LS was measured with the MAIA microperimetry (MP) and the thickness of the total, outer and inner retina in the macular sectors (central, temporal, nasal, upper and lower) using spectral-domain optical coherence tomography (SD-OCT). A comparative analysis was performed between both age groups and a correlation analysis between LS and retinal thickness in the macular area. Results: The total average LS (p˂0,0001) and by sectors decreased in the elderly group compared to the young group. The thickness of the total retina increased in central sector (p=0,0017), that of the outer retina increased in all sectors and that of the inner retina decreased in almost all its macular sectors in the elderly group. In the group of old people, the LS decreased as the thickness in the outer retina increased in the lower sector and decreased as the thickness in the inner retina in the nasal sector decreased. For the total sample, the LS decreased as the thickness of the total retina increased in the central sector and the outer retina in the central, nasal, upper and lower sectors. On the other hand, the LS decreased as the thickness in the inner retina decreased in the temporal, nasal and upper sectors. Conclusions: LS decreased as the thickness in the outer retina increased and as the thickness in the inner retina decreased in the total sample and in the group of old people.
