Cysts of the vitreous are an unusual clinical finding, with only about 50 such cases reported in the literature. The sizes of the cyst may vary from 0.15 to 12 mm, and they have been found in the anterior and posterior vitreous. The etiology has been theorized to be both congenital and acquired. Acquired cysts may be due to trauma or other forms of intraocular inflammation. Pigmented cysts are believed to originate from the pars ciliaris and nonpigmented cysts are likely to be derived from the remnants of the hyaloidal artery system. The appearances of the cysts are striking and are often seen as clear spherical bodies in the vitreous with interesting interlacing surface patterns. The cysts are benign and are of little significance, except when they encroach on the visual axis and produce visual disturbances (usually floater symptoms).
玻璃体囊肿是一种不常见的临床发现，文献中仅报道了约50例此类病例。囊肿大小从0.15毫米至12毫米不等，可见于玻璃体前部和后部。其病因被认为既有先天性的，也有后天获得性的。后天性囊肿可能由外伤或其他形式的眼内炎症引起。色素性囊肿被认为起源于睫状体，而非色素性囊肿可能来源于玻璃体动脉系统的残余部分。囊肿的外观很显著，在玻璃体中常表现为透明的球体，具有有趣的交错表面形态。这些囊肿是良性的，通常意义不大，除非它们侵犯视轴并产生视觉障碍（通常是飞蚊症症状）。
