Table 1. Mean peak, linear and area densities in vitrectomised and non-vitrectomised eyes.
Abstract
Objective

To determine whether vitrectomised eyes have a higher lens optical density, when measured with a Scheimpflug camera, compared to non-vitrectomised eyes.

Method

The peak and linear Scheimpflug optical density (DOS), and area of both eyes were measured in a sample size of 81 vitrectomised phakic patients. A comparison was made between the DOS of the vitrectomised eye lens and the contralateral non-vitrectomised eye using the Student's t-test.

Results

A significantly higher linear DOS and area was obtained in the 81 vitrectomised phakic eyes when compared to the non-vitrectomised eyes (p<0.001). The peak DOS is not significantly increased in respect to non-vitrectomised eyes (p=0.59).

Conclusions

The lens DOS in vitrectomised eyes is higher than in non-vitrectomised eyes. The importance of the vitreous in the maintenance of lens transparency is emphasized.

Resumen
Objetivo

Determinar si los ojos vitrectomizados presentan una mayor densidad óptica cristaliniana, medida con cámara Scheimpflug, con respecto a los ojos no vitrectomizados.

Método

Se selecciona a 81 pacientes fáquicos vitrectomizados a los que se les mide la densidad óptica Scheimpflug (DOS) pico, lineal y de área, de ambos ojos. Comparamos las medias de DOS del cristalino del ojo vitrectomizado y del contralateral no vitrectomizado, mediante el test t de Student.

Resultados

En 81 ojos fáquicos vitrectomizados se han obtenido unas DOS medias, lineales y de área posvitrectomía significativamente mayores respecto a los ojos no vitrectomizados (p < 0,001). La DOS pico no resultó significativamente mayor con respecto a los ojos no vitrectomizados (p = 0,59).

Conclusiones

En ojos vitrectomizados encontramos mayor DOS cristaliniana que en ojos no vitrectomizados. El gel vítreo resultaría importante en el mantenimiento de la transparencia del cristalino.
