Effectiveness of Artificial Tears in the Management of Evaporative Dry Eye

Seventy-five subjects with dry eye were randomly divided into three groups to compare the efficacies of  sodium hyaluronate, hydroxypropyl methylcellulose (HPMC) and a new oil-in-water emulsion (Emustil unidose; SIFI) in the management of lipid-deficient dry eye. Each was allocated sodium hyaluronate, HPMC or emulsion eyedrops to be used four times daily for 90 days. Parameters were measured at baseline, 30 days and 90 days. A compliance visit was performed at days 7 and 60.

Significant reduction in evaporation and improvement in symptoms in all groups were found. No statistically significant increase in tear turnover rate (TTR) was found with any solution. A significant difference in tear stability and non-invasive tear break-up time (NITBUT) was found in the emulsion and sodium hyaluronate groups but not in the HPMC group. There was a significant decrease in osmolarity and corneal staining in the emulsion group but not in the sodium hyaluronate or HPMC group.

A significant reduction in evaporation and improvement in symptoms in all therapy groups were found from baseline to 90 days. However, no significant effect was seen on TTR for any group. The emulsion drops were shown to perform best, improving tear stability, and decreasing osmolarity and corneal staining. These results are consistent with improvements in the lipid layer of the tear film as a result of prolonged use of emulsion drops.

PROYECTO UNO : UN RECUERDO DE LOS 90

Encontré estas canciones de proyecto uno y otros grupos que me traen recuerdo los años 90, cuando era universitario, cuando nos reuníamos con mis amigos que terminaron la secundaria conmigo pero que nos seguíamos viendo para tonear, escuchar música y tomar algo de ron….tiempo aquellos… saludos a Juank que ahora esta en lima, al igual que eduardo, toño y arturo que sigue aqui en la misma ciudad que yo. Tremendos fines de semana que nos dabamos saliendo de la universidad en la casa de juank o en mi casa haciendo fiestas espontáneas, pobres mis viejitos, eran épocas universitarias. Ojala algún día podriamos reunirnos a recordar épocas gloriosas, pero ahora con esposas e hijos…. Saludos a todos

Les subo unos videos de esas epocas.

Mira esta mujer girando, y si ves que ella está girando hacia la derecha, está funcionando el lado derecho de tu cerebro. Si ves que ella está girando hacia la izquierda, es el lado izquierdo de tu cerebro el que está funcionando. Y si logras verla girando en los dos sentidos… tienes un IQ de más de 160.
