To discuss the diagnosis and differential diagnosis of isolated congenital inferior oblique paresis.
13 patients with isolated congenital inferior oblique paresis examined and operated between 1984 and 1994 in our hospital were retrospectively reviewed.
After a follow-up of 6-75 months, six patients had excellent surgical results, and the rest had improvement.
Isolated congenital inferior oblique paresis occurs infrequently. Its diagnosis is based on the following: (1) presence of vertical deviation in primary position, (2) the results of duction and version examination, (3) negative forced duction test that is different from the test in Brown's syndrome. Surgery is usually indicated in most patients. It consists of weakening superior oblique muscle and recession of inferior rectus muscle in the homolateral eye and recession of superior rectus in the contralateral eye.
