Inner retinal layers11/15/2023 Many reports have demonstrated a relationship between vision loss associated with ERM and disruption of the ellipsoid zone and outer photoreceptor segments. With the introduction of SD-OCT, clinicians can also evaluate microstructural changes of the macula region both qualitatively and quantitatively, which is needed to assess the severity of ERM and to predict possible vision loss. More recently, imaging techniques, such as spectral-domain optical coherence tomography (SD-OCT) with three-dimensional reconstruction, have been introduced for this purpose. ĮRMs were initially diagnosed and classified based on clinical findings alone. Although ERMs may develop secondary to cataract surgery, retinal detachment, retinal vein occlusions, diabetic retinopathy, or uveitis and retinal tearing, most cases are idiopathic. ![]() ERM involving the macular or peri-macular regions can cause visual impairment, metamorphopsia, micropsia, and occasionally monocular diplopia. The SD-OCT staging system according to the presence of EIFL is effective for grading retinal damage and visual loss in eyes with ERM.Įpiretinal membranes (ERMs) are avascular fibrous layers characterized by abnormal fibrocellular proliferation on the inner retinal surface with a prevalence ranging from 2.2 to 28.9%, and they are more common in elderly people. VA was better in eyes with stage 1 or 2 ERM than stage 3 or 4 ERM ( p 0.05). Of 121 eyes with ERM, 23.1% had stage 1, 26.5% had stage 2, 39.7% had stage 3, and 10.7% had stage 4 disease. ERM stages were defined based on the SD-OCT staging system as stage 1: negligible morphological or anatomical disruption, retinal layers, and foveal pit are identified stage 2: characteristic stretching of the outer nuclear layer, absence of foveal depression, retinal layers are identified stage 3: continuous EIFL crossing the central foveal area, absence of foveal depression, retinal layers are identified and stage 4: anatomical disruption of the fovea, continuous EIFL crossing the entire foveal area, retinal layers are distorted. ![]() Subjects/MethodsĪ total of 242 eyes of 121 patients with unilateral idiopathic ERM were prospectively evaluated. To evaluate the relationship between the presence of ectopic inner foveal layers (EIFL), choroidal thickness, and visual acuity (VA) in patients with epiretinal membranes (ERM) staged by spectral-domain optical coherence tomography (SD-OCT).
