Lens density measurement with Scheimpflug camera in vitrectomised eyes

Abstract

ObjectiveTo determine whether vitrectomised eyes have a higher lens optical density, when measured with a Scheimpflug camera, compared to non-vitrectomised eyes. MethodThe 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. ResultsA 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). ConclusionsThe 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.
