What is the surface area of the vitreous humour in contact with aqueous humour? This is a question regarding the anatomy of the human eye, however for my purposes medium sized mammals should do. I am interested in estimating the surface area of the hyaloid membrane of the vitreous humour which has contact with the aqueous humour circulating in the posterior and anterior chamber of a typical human eye. The surface area in question is highlighted in red in this schematic of the cross section of the human eye. ![Anatomical schematic of the human eye.](

Area=πr², d≈2cm (less than maximal d) -> r≈1cm, thus the area in question is roughly

3.14*1cm*1cm≈3.14cm²

UPD by request (ref):

The vitreous body base middle is at ora serrata (+-2mm), so we should calculate the area at this level. Here is the reference of the diameter:
