    Contrast sensitivity and disability glare in patients with dry eye
    (Acta Ophthalmologica Scandinavica, 2006) Puell Marín, María Cinta; Benítez Del Castillo Sánchez, José Manuel; Martínez De La Casa Fernández-Borrella, José María; Sánchez Ramos, Celia; Aladro Vico, Eva; Pérez Carrasco, María Jesús; Pedraza Aranda, Constanza; Hierro Zarzuelo, Almudena, del
    Purpose: To evaluate contrast sensitivity and disability glare in patients with dry eye using the Contrast Glaretester 1000. Methods: Contrast sensitivity and disability glare were determined in 33 eyes of 33 patients with dry eye and 30 eyes of 30 healthy control subjects for six target sizes with a visual angle of 6.3-0.7 degrees using the Contrast Glaretester 1000, whose working mechanism is similar to that of the conventional perimetry instrument. Results: Contrast sensitivity was significantly worse in dry eye group when viewing all target sizes (reduction of 0.10-0.25 log contrast units, p < 0.01) except at 6.3 degrees. In the presence of glare, differences in log contrast sensitivity between the groups (0.10-0.25 units) were significant (p < 0.01) for all target sizes, with the dry eye group showing worse results. The reduction in contrast sensitivity induced by glare (disability glare) was significantly worse in the dry eye group versus the control group but only for the 2.5-degree size target, where 0.14 log contrast units were lost. Conclusions: Contrast sensitivity with and without glare was significantly reduced in patients with dry eye compared with control subjects, but the number of log contrast units lost with glare (disability glare) was similar in the two groups, except for the 2.5-degree size target.

    Efecto del hialuronato sódico (0.15%) en la sensibilidad al contraste de ojos secos por déficit hormonal.
    (2005) Sánchez Ramos, Celia; Llorens Casado, María Belén; Moral Martínez, M.I.; Gonzalvo, M.T.; Langa Moraga, Antonio; Pérez Carrasco, María Jesús; Sáenz Francés, F.; Puell Marín, María Cinta
    La función de sensibilidad al contraste (FSC) permite valorar el estado de la percepción espacial del sistema visual. El ojo seco es una patología que provoca visión borrosa por la pérdida de calidad óptica de la película lagrimal debido a cambios en la composición y/o regularidades en el espesor, algunas veces originadas por variaciones hormonales como pueden ser los procesos posmenopáusicos. El tratamiento más frecuente para esta pagología son las lágrimas artificiales. El objetivo de este trabajo es valorar en mujeres con déficit hormonal debido a la menopausia, el efecto de la pauta y dosis de hialuronato sódico para conocer si se recuperan los valores normales de sensibilidad al contraste (SC)
