Foveal traction
WebNov 14, 2024 · Foveal elevation of the inner retina, including nerve fiber layer (NFL) to OPL, or loss of foveal depression is caused by a taut and flat ERM at first. Usually, a single cystic space emerged in the HFL/OPL layer under persistent ERM traction. Subsequent rupture of ILM, and layers involving Muller cell process at the foveal area created a true LMH. WebDiagnosis Signs Using slit lamp or direct/indirect ophthalmoscopy, clinically significant foveal edema and retinal thickening more than 300 μm can be seen as a loss of foveal reflex; this is better visualized using green light to outline the cystic spaces.

Web• Myopic traction maculopathy (MTM) includes retinal thickening, a macular retinoschisis-like structure, lamellar MH, and foveal RD (FRD), and is considered to develop due to a complex of traction forces from adherent vitreous cortex, ERM, ILM, retinal vessels, and posterior staphyloma.
WebMay 11, 2024 · There are four major traction mechanisms identified in MTM: (1) Peri foveal vitreomacular traction (2) Cortical vitreous remnants after (PVD) development (3) Epiretinal membrane formation (4) Intrinsic non-compliance of the internal limiting membrane (ILM) and inner retina to conform to the shape of the posterior staphyloma [ 14, 15 ].

WebJan 12, 2024 · A similar case of vitreomacular traction with LHEP at the foveal walls is shown in Fig. 3h. The traction caused an elevation of the foveal center which further developed into a FTMH associated with the formation of edematous cysts in the foveal walls; the FTMH also displayed LHEP at the vitreal surface of the foveal walls.
