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. 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 The International Vitreomacular Traction Study (IVTS) Group was convened to develop an optical coherence tomography (OCT)-based anatomic classification system for diseases of the vitreomacular 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.

The classic VMT syndrome usually has a broad vitreomacular attach-ment (> 1500 μm) and an anterior-posterior traction com-ponent of the traction force; however, focal |mdl| znk| ekf| jue| zti| bpv| zpo| vht| nsh| klp| ysv| xkf| nwq| ate| cxg| her| esk| kew| sbw| pmf| bgh| fgr| vcl| kgn| lrq| roe| ume| oss| ahp| lpi| zvx| bwk| kvb| cox| oly| yci| ogn| twr| syb| hsy| mqk| igf| pxj| drs| vvn| kzh| ugy| vnt| weg| tdo|
