Heavy Eye Syndrome – Case Report

Abstract

This paper aims to report clinical features, differential diagnosis and successful surgical outcome of a patient with myopic strabismus fixus, also known as Heavy Eye syndrome (HES). We present a case of a 47-year-old man who presented to the Ophthalmology Department with diplopia and poor vision. In the past, he had been diagnosed with Graves’ disease, high myopia, and secondary open-angle glaucoma. He had undergone orbital decompression and cataract surgery of both eyes. On examination, the patient had esotropia and hypotropia with limited abduction and elevation. The patient was ultimately diagnosed with HES. Yokoyama’s surgery combined with a medial rectus muscle recession in the right eye, were performed. The procedure reduced esotropia, hypotropia and improved ductions.
