Ectopic lens

Under normal circumstances, the lens is suspended from the ciliary body by the lens ligament, and its center is almost the same as the visual axis. Part or all of the lenticular ligament of the lens is damaged or broken due to congenital, trauma, or pathological changes, resulting in an imbalance or loss of the hanging force of the lens, which can cause the lens to leave the normal physiological position. . According to the degree of the ligament defect or detachment (partial or complete), the lens ectopic is divided into subluxation and luxation / dislocation. According to the etiology, the lens ectopic is divided into congenital, spontaneous and traumatic.
