During the last decade optical coherence tomography (OCT) extended the possibilities for in vivo macula diagnostic and was increasingly used for pre- and post-operative imaging of retinal diseases. Spectral-domain optical coherence tomography (SD-OCT) with its increased scanning speed and image-resolution provides more detailed information of microstructures in the macula. Epiretinal membrane (ERM) is a disorder involving the posterior pole of the eyeball. It can be idiopathic or caused secondarily in various ocular conditions, such as uveitis, trauma, retinal detachment or retinal vascular diseases. In patients who suffer from loss of vision and metamorphopsia, vitrectomy and membrane peeling is usually performed to remove the ERM.
