abnormal anterior eye segment morphology abnormal cilary zonule morphology any structural anomaly of the circumferential suspensory ligaments that anchor the lens to the ciliary process and are made of bundles of fibrillin microfibrils, an elaborate system of fibers that spans the gap between the lens and the adjacent nonpigmented ciliary epithelium; this fibrous rigging ensures lens centration; in species that accommodate, the zonule transmits the forces that flatten the lens, allowing the eye to focus on distant objects MP:0014176 abnormal suspensory ligament of lens morphology abnormal Zinn zonule morphology abnormal apparatus suspensorius lentis morphology abnormal Zinn's zonule morphology abnormal zonula ciliaris morphology
