To define the clinical findings, cause, and outcome of patients with foveal cysts due to vitreous traction.
Follow-up of 18 patients with foveal cysts and no posterior vitreous detachment (PVD). Changes were documented in visual acuity, the appearance of the fovea, or the development of a macular hole or PVD. We studied 8 eyes using the retinal thickness analyzer.
On follow-up, 9 of 23 eyes did not develop a PVD and still had a foveal cyst; 8 of 23 developed a full-thickness macular hole; 4 of 23 developed a PVD with resolution of the cyst; and 2 eyes underwent vitrectomy for the cyst before a full-thickness hole developed. Analysis with the retinal thickness analyzer showed splitting within the middle retinal layers and in some cases unroofing or absent inner retinal layers in the center of the cyst.
Foveal cysts are caused by vitreous traction. These eyes may remain stable, develop full-thickness holes, or develop a PVD with resolution of the cystic changes. A foveal cyst seems to be a common finding in patients with foveal traction from a variety of mechanisms.
明确因玻璃体牵拉导致的黄斑囊肿患者的临床表现、病因及预后。
对18例有黄斑囊肿且无玻璃体后脱离（PVD）的患者进行随访。记录视力、黄斑外观、黄斑裂孔或PVD的发生情况。我们使用视网膜厚度分析仪对8只眼进行了研究。
随访时，23只眼中有9只未发生PVD且仍有黄斑囊肿；23只眼中有8只出现了全层黄斑裂孔；23只眼中有4只发生了PVD且囊肿消退；2只眼在全层裂孔形成前因囊肿接受了玻璃体切除术。视网膜厚度分析仪分析显示，囊肿中央视网膜中层出现劈裂，部分病例内视网膜层掀开或缺失。
黄斑囊肿由玻璃体牵拉引起。这些眼可能保持稳定、发展为全层裂孔或发生PVD且囊肿性改变消退。黄斑囊肿似乎是各种机制导致黄斑牵拉患者的常见表现。
