What is metamorphopsia?
Metamorphopsia (“meta-more-FOP-see-ya”) is a medical term used to describe an abnormal visual perception in which images appear distorted. For example, straight lines appear curved or jagged. It is an important symptom of retinal disease. Metamorphopsia is not caused by the need for new glasses, cataract, glaucoma, or optic nerve damage. Metamorphopsia is a sign of a retinal problem. It is detected and monitored with an Amsler grid.
What causes metamorphopsia?
The retina is a thin layer of nerve tissue that acts like film inside a camera. The retina “takes a picture” and sends the image to the brain. The root cause of distortion in vision is a retina that is not smooth and flat against the eye wall. This distortion of the retina may be caused by many different conditions. Sometimes, problems under the retina cause fluid leakage resulting in metamorphopsia. Such conditions include macular degeneration, central serous retinopathy, histoplasmosis, high myopia, angioid streaks, and inflammation. In other situations, distortion may be caused by scar tissue under the retina from inflammation, trauma, bleeding, or chronic leakage of fluid under the retina. Distortion of the retina may also be caused by vitreomacular traction, macular hole, or macular pucker. The ophthalmologist (retinal specialist) will undertake examination and testing to determine the cause.
Is metamorphopsia an urgent situation?
Metamorphopsia may be an urgent situation if it is new in onset or has significantly increased recently. If the cause of distortion is inflammation or bleeding, prompt treatment is needed to prevent further loss of vision and worsening of symptoms. Longstanding distortion is less likely an emergency but merits an eye examination to determine the cause.
What is the treatment?
Metamorphopsia is a symptom rather than a diagnosis, so the treatment depends on the underlying cause of the distortion of vision. This is the reason why it is important to have an eye examination in order to determine the best course of action. Contact your eye doctor or retinal specialist if you have this important symptom.
