Doc, Can You Straighten My Eyes? III

This middle-aged woman with a past history of hyperthyroidism presented with severe thyroid eye disease. Both eyeballs were constantly depressed due to fibrosis of the inferior rectus muscles (the muscles that are responsible for moving the eyes downwards). And she had severe dry eyes due to eyelid retractions.

download and lid retractions.

Inability to look up due to severe contracture 
of the inferior rectus.

The depressed eyeballs were corrected by releasing the inferior rectus muscles. Following the squint correction, she was able to see straight without having to constantly elevate her heads. The lid retractions were corrected with botox injection to the levator muscles.
