Biomicroscopic vitreous videography
1Department of Ophthalmology, Asahikawa Medical College, Japan.
Purpose:
The authors report on the technique of biomicroscopic vitreous videography using the recently developed charge coupled device (CCD) video camera.
Methods:
The authors performed biomicroscopic vitreous videography using the CCD video camera connected to a slit-lamp biomicroscope to examine 50 eyes with age- or disease-related vitreous changes in 50 patients. The cases were categorized as follows: 20 normal senile eyes; 10 eyes with retinal breaks; 10 eyes with diabetic retinopathy; 5 eyes with uveitis; and 5 eyes with high myopia. Noncontact positive preset lenses were used for observing the posterior vitreous; a wide-angle funduscopic contact lens and a three-mirror contact lens were used to observe the peripheral vitreoretinal changes.
Results:
Using the CCD video camera, dynamic vitreous changes were documented clearly using real-time television monitoring. The video system also allowed rapid review of the vitreous changes.
Conclusion:
This new biomicroscopic vitreous videography system will contribute to the study of vitreoretinal diseases and be valuable as an educational tool.
