Ptosis is one of the conditions most commonly encountered by an ophthalmologist, particularly by an oculoplastic surgeon. Owing to the diversity of presentation, clinical and pathological types, surgical options for management and ultimate outcome, ptosis continues to baffle even the most experienced surgeons. Clinical examination is the most important part in the management of ptosis. It gives us information about the type of ptosis, degree of severity and any complicating factors, all of which is essential to decide on the surgery and the amount of correction desired. Safety of the surgery and the expected outcome can also be predicted to a certain degree. In this video, we illustrate the basics of history taking and examination techniques in any case of ptosis.
