Ophthalmoparesis is a medical condition that affects the eye muscles and causes weakness or paralysis. Some synonyms for ophthalmoparesis include eye muscle weakness, eye movement dysfunction, ocular muscle impairment, and ptosis (drooping of the eyelid). Other terms used to describe the condition include ophthalmoplegia, which is the complete paralysis of the eye muscles, and strabismus, which is the misalignment of the eyes. Ophthalmoparesis can occur due to various underlying medical conditions, such as stroke, multiple sclerosis, myasthenia gravis, or brain tumors. Treatment options for ophthalmoparesis vary depending on the underlying cause and may include medication, surgery, or therapy.
