Metamorphopsia is a symptom that occurs in many macular and retinal conditions, including age-related macular degeneration (AMD), macular puckers, macular edema, and retinal detachment. With metamorphopsia, straight lines and linear objects appear wavy, distorted, or rounded. In some cases, faces can even appear distorted. Metamorphopsia can also include micropsia and macropsia, which is when objects appear smaller or larger, respectively. Metamorphopsia is commonly diagnosed using an Amsler grid. Amsler grids can also be used at home to help patients monitor their vision health, detect any visual disruptions, and report their symptoms to their ophthalmologist.
