Twenty-four patients (31 eyes) with choroidal folds unassociated with
orbital tumors were evaluated with standardized echography. Hypermetropia
was the most commonly associated finding (eight eyes); in ten eyes, no
consistent abnormal findings could be established. Among the less common
causes were swelling of the optic nerve proper or the perineural sheaths
and thickened extraocular muscles. Standardized echography demonstrated
ocular changes, orbital changes, or both, in all but two patients (two
eyes) with idiopathic folds. The most frequent findings were flattening of
the posterior ocular wall (18 eyes), thickening of the retinochoroid layer
(12 eyes), and distention of the optic nerve sheaths (eight eyes). While
fluorescein angiography is well established as the preferred method of
demonstrating choroidal folds, standardized echography may now be used to
delineate the often subtle associated ocular and orbital findings.
