A case report reveals effective correction of diplopia due to hyperthyroidism in a patient, suggesting implications for optometric care.
A patient with undiagnosed hyperthyroidism sought oplometric care because of newly developed diplopia. The patient was referred to her general physician who diagnosed and treated the glandular disorder. The diplopia. apparently caused by a paralysis of the superior rectos muscle not uncommon in hyperthyroidism, created a manifest vertical deviation on straight ahead gaze but not on down gaze. A spectacle correction with tase‐down prism was prescribed for distance viewing: a slab‐off prism to compensate for the absence of a vertical deviation while doing near work was incorporated.
