When this happens, the proteins can stick together and form whitish, yellow, or brown clumps that cover the natural lens of your eye. Cataract surgeryĬataracts are caused by proteins that can change or break down inside your eye. Other potential vision concerns depend on the type of surgery you’ve had, as well as the type of anesthesia used. In fact, any operation on or around your eyes may result in temporary vision changes, including blurry vision. All rights reserved.What types of eye surgery most often cause blurry vision?īlurry vision can be a common side effect of eye surgeries. Thompson, MD SPANISH SERIES EDITORSĬopyright © The Foundation of the American Society of Retina Specialists. Surgery for ERM has a good success rate, and most patients experience improved visual acuity and decreased metamorphopsia following vitrectomy.Īuthors THANK YOU TO THE RETINA HEALTH SERIES AUTHORS The cause of the ERM (Idiopathic ERMs have a better prognosis than eyes with prior retinal detachment or retinal vascular diseases.Length of time the ERM has been present.Patients who still have their natural lens will develop increased progression of a cataract in the surgical eye following surgery.įactors affecting visual outcome include: The risk of complications with vitrectomy is small, with about 1 in 100 patients developing retinal detachment and 1 in 2000 developing infection after surgery. Visual recovery is slow and most eyes experience improvement within 3 months but it may take a year to attain maximal visual acuity improvement. This allows access to the surface of the retina where the ERM can be removed with delicate forceps, thereby allowing the macula to relax and become less wrinkled. With vitrectomy, small incisions are placed in the white part of the eye, and the vitreous gel filling the inside of the eye is replaced with saline. A surgical procedure called vitrectomyis the only option in eyes that require treatment. There are no eye drops, medications or nutritional supplements to treat ERMs. Since most ERMs are fairly stable after an initial period of growth, they can simply be monitored as long as they are not affecting vision significantly. In rare circumstances, the membrane will spontaneously release from the retina, relieving the traction and clearing up the vision. However, if an exam shows progression and/or functional worsening in vision, surgical intervention may be recommended. Epiretinal Membrane Sharon Fekrat, MD, FACS, Duke University Eye Center. If there is no specific cause apart from the PVD, the ERM is called idiopathic (of unknown origin).ĮRMs can be associated with a number of ocular conditions such as prior retinal tears or detachment, retinal vascular diseases such as diabetic retinopathy or venous occlusive disease they can also be post-traumatic, occuring following ocular surgery, or be associated with intraocular (inside the eye) inflammation.įigure 2. The most common cause of macular pucker is an age-related condition called p osterior vitreous detachment (PVD), where the vitreous gel that fills the eye separates from the retina causing symptoms of floaters and flashes. This membrane can appear like cellophane and over time may contract and cause traction (or pulling) and puckering of the retina, leading to decreased vision and metamorphopsia. The cause of ERMs is due to a defect in the surface layer of the retina where a type of cell, called glial cells, can migrate through and start to grow in a membranous sheet on the retinal surface. Less commonly, ERMs may also be associated with double vision, light sensitivity or images looking larger or smaller than they actually are. Patients may notice metamorphopsia, a symptom that causes visual distortion in which shapes that are normally straight, like window blinds or a door frame, looking “wavy” or “crooked,” especially when compared to the other eye. In advanced cases, this can lead to severely decreased vision. In such cases, patients typically have normal or near-normal vision. However, ERMs can slowly progress, leading to a vague visual distortion that can be perceived better by closing the non- or less-affected eye. Most patients with ERMs have no symptoms their ERMs are found incidentally on dilated retinal exam or on retinal imaging such as with ocular coherence tomography (OCT).
