Heavy eye syndrome (HES) is an acquired strabismus typically seen in eyes with high myopia. We report a classic case in which a patient was misdiagnosed with esotropia and underwent disinsertion of the medial rectus muscle and lateral rectus muscle resection procedures.
A 71-year-old woman presented with both eyes fixed in adduction and infraduction for 33 years. She had undergone three complicated strabismus surgeries to amputate the left medial rectus (MR) muscle with lateral rectus mus
The Yokoyama procedure was effective in correcting HES.
Core Tip: In highly myopic patients, excessively long axial length can cause a type of myopia-induced strabismus, characterized by progressive esotropia and hypotropia, which means the enlarged globe displace between the superior rectus and lateral rectus muscles. In this case report, a woman had been misdiagnosed with simple esotropia and had undergone three recession-resection surgeries with no improvement. We performed a Yokoyama procedure, and her eyes remained binocularly aligned for 6 mo postoperatively.
