Development of visual acuity [PDF]
A hand-held electrically operated instrument has been devised to assess visual acuity by means of the phenomenon of opto-kinetic fixation nystagmus. An accurate determination of visual acuity has been obtained from an early age, and a graph of the normal visual acuity development produced. It has been confirmed that adult acuity is reached by 3 years

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