Thank you for the fantastic explanation, your channel is an absolute treasure! . I have a question as i am dealing only with adult patients, if the patient presented to me with clear left eye esotropia and paralysis of abduction (2ry to left 6th nerve palsy), what is the point from doing the mal alignment tests like alternate cover, cover uncover or maddox rod?

[@InsightOphthalmology]

Thank you ! Can you please reframe your question?

[@Rayan-tr2dm]

@@InsightOphthalmology I mean, If the esotropia and limitation in eye abduction is obvious from simple examination of eye movements, what is the added benefit of testing mal alignment with cover-uncover or maddox rod?
