The crypts are little squiggly lines that radiate out around the pupil; with this condition, thick round or oval openings can be seen.On diagnosis, signs lead to symptoms where there is more than one set of iris muscles, which controls the amount of light being brought into the eye. When the iris becomes deformed, it will disarrange the control of light coming in leading to blurred vision and finding it hard to visually focus. Polar cataracts will also be present in this condition where a round, opaque malformation of distorted lens fibers is located in the central posterior part of the lens showing disformality. Blindness may also be caused due to damage of the optic nerve from glaucoma. Treatment
Polycoria has been linked to hereditary genetics, and also associated with polar cataracts, glaucoma, and retinal detachment. Not all cases are treated for this iris abnormality, but when cases are treated the only treatment is surgical procedure and life-long ocular monitoring that is highly recommended. Considerations for surgery are surgical correction, intraocular surgery, and/or reapproximation, as if it was being treated for glaucoma or retinal detachment. Children under the age of 3, who do not seek surgical surgery, have responded well with miotic drops that contained mydriatic/cycloplegic, allowing the separate eye sphincters to dilate and constrict together. This allows improved  balance of uncorrected visual acuity.
Preliminary in vivo experiments show a decrease in C(max) and a longer half-life with the liposomal formulation. The drug antibody eribulin combination therapy is a joint venture between Eisai and Merck. The clinical trials combine eribulin and pembrolizumab, a PD-1 inhibitor, for the treatment of breast cancer and other advanced cancers. Intellectual Property
Currently there are five active patents in the United States that are associated with the Halaven drug application, N201532. The first one expired on June 16, 2019, the last one (USRE46965) expires on January 8, 2027. References
