Metamorphopsia

Metamorphopsia is a type of visual distortion where the individual perceives straight lines as wavy or bent. It is often associated with conditions affecting the eye or brain, such as macular degeneration, macular edema, epiretinal membrane, or migraines.

Causes

The most common cause of metamorphopsia is macular degeneration, a condition where the macula, the part of the retina responsible for central vision, deteriorates. Other causes include macular edema, where fluid accumulates in the macula, and epiretinal membrane, a thin layer of fibrous tissue that can develop over the retina.

Symptoms

The primary symptom of metamorphopsia is the distortion of vision. Straight lines may appear wavy or bent, and objects may appear larger or smaller than they actually are. This can make tasks such as reading or driving difficult.

Diagnosis

Diagnosis of metamorphopsia typically involves a comprehensive eye examination, including a visual acuity test, a dilated eye exam, and imaging tests such as optical coherence tomography (OCT) or a fluorescein angiography.

Treatment

Treatment for metamorphopsia depends on the underlying cause. For conditions such as macular degeneration or macular edema, treatment may involve medication, laser therapy, or surgery. In some cases, no treatment is necessary, and the condition will resolve on its own.
