Transthyretin levels in the vitreous correlate with change in visual acuity after vitrectomy [PDF]

open access: yes, 2009
Background/aim: Little is known about biochemical markers related to change in visual acuity after vitrectomy. The potential use of transthyretin (TTR), a carrier of the retinol/retinol-binding protein, as a biochemical marker protein, was investigated ...
