  • Abstract
  • Look Inside

We treated 12 patients with thyroid ophthal-mopathy with beta-blocker ophthalmic solutions instilled twice daily. All the patients manifested widening of the palpebral fissure due to upper lid retraction as manifestation of the disease. We em-ployed timolol befunolol or carteolol in the treat-ment. Three patients responded favorably to the treatment. Significant improvement in upper lid retraction set in after 3 weeks to 3 months of treatment in them.

Upper lid retraction in hyperthyroidism is claimed to result from hypertoxicity of superior and inferior tarsal muscles which are under sympa-thetic innervation. The sympatholytic action of beta-blockers would reduce the spasm of the tarsal muscles and induce improvement in the widened palpebral fissure.
