Abstract

We have shown that by using the information available in a standard scan, one can estimate the loss of fluorescence signal at the anterior vitreous. The proposed method is restricted to lenses without cataracts, which is not a serious limitation because vitreous fluorophotometry is not performed on cataractous lenses. The procedure is easily implemented and requires only the use of an instrument with good axial resolution and reliable alignment with the ocular optical axis.

We have raised the question whether this estimate provides all the information for locations deep inside the vitreous. This issue should be studied further.
