WebApr 15, 2024 · While the drug can be very effective for the aforementioned illnesses, it can cause a rare side effect of bilateral angle-closure glaucoma via the development of ciliochoroidal effusions. These effusions can cause anterior rotation of the ciliary body and anterior displacement of the lens–iris diaphragm [ 14 ]. WebCiliary body. The ciliary body is a circular structure that is an extension of the iris, the colored part of the eye. The ciliary body produces the fluid in the eye called aqueous humor. It also contains the ciliary muscle, which changes the shape of the lens when your eyes focus on a near object. This process is called accommodation.
