Reliability of Ptosis diagnosis on assessment via video consultation

ePoster Number: 278


To examine the reliability of adult ptosis assessment in video consultation


This is a retrospective, comparative, case series. The surgical waiting list for ptosis surgery between August 2020- January 2021 was checked and only cases listed for surgery via video consultation assessment, without any previous face-to-face consultation, were included. The following data were collected for patients who underwent video consultation before surgery: Demographic data, date of video consultation, level of experience of clinician (Consultant/ Fellow/ Resident), side of ptosis, levator function, Cogan’s twitch sign, fatigability test, eye motility, presence of lagophthalmos, questions to rule out Myasthenia Gravis or other myopathies, if the surgery was performed/cancelled, date of surgery, type of procedure, side and surgeon experience.


176 patients underwent ptosis surgery between 8/2020 to 1/2021. From them, 45 patients (25.6%) had a video assessment only prior to surgery when ptosis was diagnosed and patient was listed for surgery. Video consultation was done by: Consultant: 30 cases (67%); Fellow: 15 cases (33%). 36 patients (80%) eventually underwent ptosis surgery. Surgery was cancelled in 20% of the cases. It was due to: surgery no longer required due to misdiagnosis of ptosis confirmed on the day of surgery during pre-surgical face-to-face assessment in 2 cases (4.44%). Although ptosis was confirmed in the other 7 cases (15.55%) surgery was cancelled for other reasons. Reliability of ptosis assessment via video consultation was correct in 43 cases (95%) (p_value=0.156, chi_ square). In most of the cases ptosis assessment in video included: Judgment of levator function, eye motility and lagophthalmos check but not all cases had Cogan’s twitch sign, fatigability test and questions to rule out Myasthenia Gravis performed.


Video consultation is an efficient and reliable way to assess patients with ptosis. Although an accurate and more thorough ptosis assessment is advised there was no difference between accuracy of diagnosing on those who did not do the full suggested assessment
