She didn\u2019t have any systematic and ocular diseases other than myopia and astigmatism.Eyelid retraction during smiling is 5\u00a0mm, resulting in a significant difference in the height of bilateral palpebral fissures.As for ptosis, is mild.The margin to reflex distance 1 is 1.0\u00a0mm on the right eye(ptosis eye) and 3.0\u00a0mm on the left eye. A lid lag of 1.0\u00a0mm on downward gaze was noted on the right, she could close her eyes fully while sleeping.The ice pack test, laboratory test for thyroid function, whole-exome sequencing (WES) and magnetic resonance imaging(MRI) of the orbital and ocular motor nerves showed normal results.Her symptoms alleviated after 6 months, with the retraction of the right upper eyelid when smiling was approximately 3\u00a0mm, thus the difference in the palpebral fissure height when smiling was smaller than that at the initial presentation.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Conclusion<\/jats:title>\n                <jats:p>Blepharoptosis may accompanied with abnormal innervation like eyelid retraction, this phenomenon can be alleviated with age.The results of the levator muscle function test should be carefully examined to determine whether it is ptosis in an impaired innervation eyelid.<\/jats:p>\n              <\/jats:sec>","DOI":"10.1186\/s12886-024-03485-8","type":"journal-article","created":{"date-parts":[[2024,5,31]],"date-time":"2024-05-31T16:02:08Z","timestamp":1717171328000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Eyelid retraction during smiling in a patient with monocular congenital ptosis: a case report"],"prefix":"10.1186","volume":"24","author":[{"given":"Yiyang","family":"Zhao","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jing","family":"Fu","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jie","family":"Hao","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"297","published-online":{"date-parts":[[2024,5,31]]},"reference":[{"issue":"5","key":"3485_CR1","doi-asserted-by":"publisher","first-page":"483","DOI":"10.1016\/j.survophthal.2014.01.005","volume":"59","author":"JR SooHoo","year":"2014","unstructured":"SooHoo JR, Davies BW, Allard FD, Durairaj VD.
