Fibronectin (FN) eyedrops, which has been reported to facilitate healing trophic ulcer and recurrent corneal erosion, is usually prepared from 10 ml volume of patient's own blood. The method for the preparation of this eyedrops was studied by determination of FN content. The results were as follows: 1) From 20 ml volume of blood, double concentration of FN in eyedrops could be made, or a couple of eyedrops could be done at a time. 2) FN concentration in eyedrops and area under the curve (AUC) of FN fraction had a good correlation (Y=72.2X-8.7, r=0.979, p<0.01,N=22). Therefore, it was possible to estimate FN concentration in eyedrops from AUC. 3) FN was almost lost after sterilization by filtration with nitrocellulose or mixed esters of cellulose membrane. On the other hand, FN almost remained after sterilization by filtration with polyvinylidene fluoride and acetylcellulose membrane.
