Vitreomacular traction syndrome (VTS) is a medical condition in the eye that is the result of tractional forces (pulling) being placed on the retina. [1] [2] VTS is common in people who have an incomplete posterior vitreous detachment, a type of retinal detachment at the periphery of the retina. [1]
Traction caused by VMA is the underlying pathology of an eye disease called symptomatic VMA. There is evidence that symptomatic VMA can contribute to the development of several well-known eye disorders, such as macular hole and macular pucker, that can cause visual impairment, including blindness.
Macular hole on the right eye Classification of Vitreomacular Adhesion, Traction, and Macular Hole (IVTS 2013) Macular degeneration is a condition affecting the tissues lying under the retina, while a macular hole involves damage from within the eye, at the junction between the vitreous and the retina itself. There is no relationship between ...
Epiretinal membrane or macular pucker is a disease of the eye in response to changes in the vitreous humor or more rarely, diabetes.Sometimes, as a result of immune system response to protect the retina, cells converge in the macular area as the vitreous ages and pulls away in posterior vitreous detachment (PVD).
Macular hole repair; Partial lamellar sclerouvectomy [25] Partial lamellar sclerocyclochoroidectomy; Partial lamellar sclerochoroidectomy; Posterior sclerotomy is an opening made into the vitreous through the sclera, as for detached retina or the removal of a foreign body. [26] Radial optic neurotomy; Macular translocation surgery through 360 ...
Macular holes – the normal shrinking of the vitreous humor with aging can occasionally tear the central retina causing a macular hole with a blind spot blocking sight. Vitreous hemorrhage – bleeding in the eye from injuries, retinal tears, subarachnoid hemorrhages (as Terson syndrome ), or blocked blood vessels.
Photostress recovery time (PSRT) is the time taken for visual acuity to return to normal levels after the retina has been bleached by a bright light source. Photostress recovery time measurement procedure is known as photostress test. Normal recovery time is about 15–30 seconds. [1]
Simultaneous stereo fundus photos have been published prior to 1909 however their use as a diagnostic tool is not widespread. [16] Recent advances in digital photography and 3D monitors has seen some manufacturers incorporating it once again into photographic equipment.
