To report two cases of vitreous cysts with discussion of their pathophysiology and management. Clinical examination with fundus photography, ultrasound and optical coherence tomography. Histopathology was performed in the first case. The first case illustrates a pigmented, free-floating cyst, which was removed during a 27-gauge vitrectomy. The histopathology shows a single layer of pigmented epithelium and confirms the previously reported presence of a PAS-positive basement membrane. The second case shows a sessile, non-pigmented cyst associated with significant anisometropia. Primary vitreous cysts are rare and can have a wide range in their clinical aspect. This likely reflects whether they originate either from the pigment epithelium or the primary hyaloidal system. The management of vitreous cysts is mostly conservative, but pars plana vitrectomy can be used safely if the symptoms are debilitating.
报告两例玻璃体囊肿病例，并讨论其病理生理学及处理方法。通过眼底照相、超声及光学相干断层扫描进行临床检查。第一例进行了组织病理学检查。第一例显示一个色素沉着、自由漂浮的囊肿，在27G玻璃体切割术中被切除。组织病理学显示为单层色素上皮，并证实了先前报道的PAS阳性基底膜的存在。第二例显示一个无柄、无色素的囊肿，伴有明显的屈光参差。原发性玻璃体囊肿罕见，其临床外观差异很大。这可能反映了它们是起源于色素上皮还是原发性玻璃体系统。玻璃体囊肿的处理大多是保守的，但如果症状严重，可安全地采用玻璃体切除术。
