丛林婴儿的血浆和房水之间的碳酸氢盐和Cl的分布是这样的，有一个缺乏碳酸氢盐和过量的Cl在房水中，与预期的血浆透析液的浓度相比。因此，这种物种的房水与马等大眼睛动物的类似，尽管眼睛的实际大小介于兔子和豚鼠之间。与其他物种（如家兔）相比，玻璃体液中Na 24的周转速度较快，可能是因为它是液体而不是凝胶。这表明，这种快速周转允许（充分）缓冲眼内容物，而不需要在分泌液中高水平的碳酸氢盐。水和玻璃体液中糖的相对浓度与玻璃体液更新相对较快的观点一致。
The distributions of bicarbonate and Cl between plasma and aqueous humor of the bush baby was such that there was a deficiency of bicarbonate and an excess of Cl in the aqueous humor, compared with the concentrations expected of a dialysate of plasma. The aqueous humor of this species was thus similar to that of large-eyed animals like the horse, although the actual size of the eye lies between that of the rabbit and guinea pig. The rate of turnover of Na24 in the vitreous humor was rapid by comparison with other species, such as the rabbit, presumably because it was fluid and not a gel. It was suggested that this rapid turnover permits (adequate) buffering of the eye contents without the necessity for a high level of bicarbonate in the secreted fluid. The relative concentrations of sugar in aqueous and vitreous humors was consistent with the view that the vitreous humor is renewed relatively rapidly.
