ETIOLOGY OF UPPER EYELID RETRACTION IN THYROID EYE DISEASE

In this study upper eyelid retraction was evaluated in relation to lid lag. The significance of proptosis and limitation on upgaze was also investigated. It was observed that only moderate to severe limitation on upgaze enhanced the upper eyelid retraction. Proptosis did not corr elate with upper eyelid retraction hut did correlate well with lower e yelid retraction. It was concluded that limitation on upgaze has some role in upper eyelid retraction whereas proptosis does not have a sign ificant effect.
