Metamorphopsia
Metamorphopsia
Metamorphopsia (pronunciation: /ˌmɛtəmɔːrˈfɒpsiə/) is a type of visual distortion where the sufferer perceives straight lines as wavy and objects appear distorted in size, shape, color, or position.
Etymology
The term "metamorphopsia" is derived from the Greek words "meta" meaning change, "morphē" meaning shape, and "opsis" meaning vision. Thus, it literally translates to "change in shape vision".
Symptoms
The primary symptom of metamorphopsia is the distortion of visual perception. This can manifest as seeing straight lines as wavy or bent, objects appearing larger or smaller than they actually are, or objects appearing closer or further away than they are in reality. Other symptoms may include blurred vision, double vision, and difficulty reading or performing tasks that require precise vision.
Causes
Metamorphopsia is most commonly caused by conditions that affect the retina, the layer of tissue at the back of the eye that senses light and sends images to the brain. These conditions can include macular degeneration, macular edema, macular pucker, and retinal detachment. It can also be a symptom of migraines or other neurological conditions.
Treatment
Treatment for metamorphopsia depends on the underlying cause. For conditions affecting the retina, treatment options may include medication, laser therapy, or surgery. For migraines or other neurological conditions, treatment may involve medication, lifestyle changes, or other therapies.
