What symptom does hyperthyroidism have when exophthalmos

summary

The main symptom of exophthalmos in hyperthyroidism is inflammation. It is due to the volume effect caused by the hypertrophy of extraocular muscles and the increase of orbital fat volume, as well as the movement limitation caused by muscle changes. What symptom does hyperthyroidism exophthalmos have? I share what I know with you.

What symptom does hyperthyroidism have when exophthalmos

First, bilateral or unilateral exophthalmos, eyelid hyperemia and edema, and full periorbital tissue. The upper eyelid or lower eyelid retracts and the upper eyelid falls slowly, which is called "tardy drop sign". Blink increases or decreases.

Second: bulbar conjunctival congestion and edema, severe cases out of the eyelid fissure, muscle insertion attachment conjunctival blood vessels increased, in turn, and even can see the thickening of the muscle insertion.

Third, restrictive eye movement disorder occurs when extraocular muscles are involved. Severe exophthalmos, corneal exposure can lead to exposure keratitis, especially the lower limbus of cornea, and even endophthalmitis, endangering vision.

matters needing attention

Long term elevated orbital pressure, optic nerve traction, orbital apex muscle hypertrophy can be secondary to optic atrophy, visual field defects, color vision disorders, visual electrophysiological abnormalities and other manifestations, severe visual decline, or even loss.
