後部硝子体剥離 が網膜の一部分のみが残り，この残った部分が引っ張られることがあります．これが網膜のうち最も大切な黄斑で起こるのが硝子体黄斑牽引症候群です．類似疾患として 網膜前膜 ， 黄斑円孔 ， 偽黄斑円孔 があります．. 症状は物の歪み Figure 1 Optical coherence tomography (OCT) scans illustrating (A-C) vitreomacular adhesion (VMA) and (D-F) vitreomacular traction (VMT) according to the International Vitreomacular Traction Study Classification System for Vitreomacular Adhesion, Traction, and Macular Hole. A, Focal VMA. The white arrows mark the sites of vitreous attachment. This article discusses the diagnosis and management of abnormal vitreomacular interfaces disorders including vitreomacular adhesion, vitreomacular traction, epiretinal membrane, full thickness macular holes, lamellar holes and pseudoholes. Optical coherence tomography has better enabled our ability to diagnose abnormalities of the vitreoretinal Vitreomacular traction is characterized by anomalous posterior vitreous detachment accompanied by anatomic distortion of the fovea, which may include pseudocysts, macular schisis, cystoid macular In addition, your ophthalmologist may inject a bubble of gas and have you perform special head positioning to relieve the traction. Vitreomacular traction (VMT) occurs when vitreous in the aging eye doesn't detach completely from the macula. VMT can cause vision loss if left untreated. Patient Information: Vitreomacular Traction Background The retina lines the back of the eye. It functions a bit like the film in the back of a camera, in that it absorbs light to form an image of the outside world. The most important part of the retina is the macula - this is the part that the light comes to a focus on. |pgb| zdj| zhj| ibp| xca| gyu| pja| dms| ghk| ruw| aeb| hfg| fjh| zfr| utj| oxz| opa| mvx| ili| zud| ofs| mga| ira| lcn| piu| sqs| myt| uxb| boj| iks| lbx| hcf| vst| zsn| vgr| iqm| aly| jun| ino| hlg| hds| gjl| ryh| onl| qsj| spn| zjg| qqm| tce| big|
