Does defocus induce spatial changes in choroidal thickness?  New findings in chicks study with TowardPi Wide-Field Swept-Source OCT.

In the negative lens group, the global choroidal thickness (ChT) of the treated eyes was significantly less than that of the fellow eyes on day 7, but thicker on day 21. In the positive lens group, the ChT of both eyes increased on day 7 and decreased on day 21. These results provide evidence for regionally asymmetric characteristics of the choroidal response to visual cues and insights into the underlying mechanisms of emmetropization.

Novel research findings from the team of Prof. Xingtao Zhou (Eye & ENT Hospital, Fudan University, Shanghai, etc.), published in < Experimental Eye Research >.

TowardPi BMizar SS-OCT offers the preeminent capability of capturing OCT and OCTA images for many types of animals. With no need for any additional lens, even applicable to small species such as chicks, rabbits, mice, and even zebrafish. Extraordinary optic design for not only the anterior and posterior eyes of humans but also animals.
