OCT results were related into three groups (1) Vitreo foveal traction: at the center of macula (fig-1a) (2) Extra foveal traction: vitreoretinal traction elsewhere at the posterior pole in between vascular arcades (3) Epi retinal membrane: diagnosed as difference in the brightness of surface tissues (fig-1b).
All of the various techniques utilized in the management of retinal detachment aim to create an adhesion to prevent fluid exchange between the retinal pigment epithelium (RPE) and sensorial retina in the area surrounding the retinal tear, to thus enable RPE active transport and reabsorption of the subretinal fluid, to reduce the effects of vitreoretinal traction, and to prevent new tear formation.
17) It is now accepted that the early event leading to macular hole formation is persistent vitreoretinal traction.
While this strong attraction cannot be imaged with standard fundus examination techniques, it is easily observed with OCT (see Figure 4A), where vitreoretinal traction is seen as a thin, moderately reflective band, pulling on the retina in an incomplete v-shaped PVD.
I have had a number of patients with a small, unexplained reduction in VA whose OCT examination showed a small amount of vitreoretinal traction, along with a posterior vitreous detachment (PVD) (Figure 1).
