How to view the retina of the eye? Answered

Hello everyone ,I viewed the OIO model but I am trying to do a slightly different method. I have a 20D lens and IR camera with raspberry pi . I have a problem viewing the retina of the eye . To be more precise the imaging of the retina in IR camera without pupil dilation is much difficult for me . I tried different angles in a dark room but still I can only view the anterior of the eye and the posterior is not viewed . Hope you understand the problem I am facing , can you help me in taking this project further ?

My optician uses a flash to illuminate the retina, this is so fast the pupil has no time to contract. Your sitting in a semi dark room to make your pupil dilate.
