Biomicroscopic Evaluation and Photography of Posterior Vitreous Detachment

Anatomical findings of vitreoretinal interface in eyes with asteroid hyalosis

“…In these reports, the presence of PVD was evaluated by slit-lamp biomicroscopy. The appearance of a Weiss ring was also defined as a complete PVD [12]. However, it is difficult to examine the presence of complete PVD by using the conventional method, especially in cases of AH, because the accumulation of asteroid bodies sometimes become so dense as to prevent accurate examination of the fundus.…”

Quantitative Molecular Characterization of Bovine Vitreous and Lens with Non-invasive Dynamic Light Scattering

“…To date, there has been a lack of investigational techniques that characterize vitreous and lens structure at the molecular level without disrupting the inherent molecular organization or inducing confounding artifacts. Specialized preset lens biomicroscopy (Takahashi, Trempe and Schepens, 1980) and NMR spectroscopy (Aguayo et al, 1985) of vitreous have been employed in some centers, but are not presently used routinely. While the LOCS clinical classi®cation system of lens opaci®cation (Chylack et al, 1989) has provided a more organized and systematic approach with a higher degree of reproducibility and interobserver congruity, this system involves subjective evaluations that limit its value as a quantitative assessment.…”

“…This feature has limited the utility of preset lens biomicroscopy (Takahashi et al, 1980) and ultrasonography (Green and Byrne, 1989) for research in vitreous, in spite of their utility in clinical practice. Scheimp¯ug photography of the lens has been developed as a means to quantitate lens opaci®cation, but this technique may not be sensitive enough to detect early changes Datiles, 1999).…”

Diabetic macular edema, Risk factors and concomitants

“…Intravenous fluorescein angiography were also performed. The vitreoretinal relationship was examined using a preset lens with slitlamp, which allows observation of the dynamics of the vitreous condition with high magnification of the macular area (Takahashi et al 1980). This technique was performed by the same examiner (in order to abolish the inter-observer variation) and helps differentiate a premacular liquefied lacuna from the detached premacular cortical vitreous.…”
