Biomicroscopic evaluation and photography of posterior vitreous detachment
M. Takahashi, C. L. Trempe and C. L. Schepens
This is a preliminary effort to demonstrate conditions of the posterior
vitreous more objectively by slit-lamp photography. For this purpose, a +
58.6-diopter, aspherical, preset lens (El Bayadi-Kajiura lens [Nikon]) and
a photoslit (Zeiss Jena) were used. The most fundamental aspect in our
technique of observation and photography of the posterior vitreous is that
of catching the appropriate moment during the vitreous movement that
follows horizontal and/or vertical displacement of the patient's eye.
Posterior vitreous photographs by this method in normal eyes, retinitis
pigmentosa, Wagner's disease, and preretinal macular fibrosis associated
with macular edema in phakic eyes are presented, and biomicroscopic
characteristics in each of these diseases are discussed. Our observations
clearly demonstrate a new technique for detailed examination and
photography of the posterior vitreous.
