Axial T1-weighted MR image shows bilateral fibrotic eye bulbs in both orbits (arrow). The rudimental medial and lateral recti are medially displaced (arrow head). Minimal enlargement of the lateral ventricles but no hypotense signal changes of the optic radiation can be observed.

T1-weighted sequences (Fig. 1 and 2). The extraocular muscles were inserted to the residual bulb and were medially displaced (Fig. 1). The optic nerves, the optic chiasm, the optic tracts and the optic radiations were all absent (Fig. 1-4).
Inversion recovery sequence shows the enlarged ventricles and an absence of the optic radiations (arrow).

F2
T1-weighted sequences (Fig. 1 and 2). The optic nerves, the optic chiasm, the optic tracts and the optic radiations were all absent (Fig. 1-4). The lateral ventricles were enlarged on both sides (Fig. 2). The corpus callosum was present and was slightly diminished in size (Fig. 3).
Midsagittal T1-weighted MR image shows an absence of the optic chiasm (arrow) and a normal corpus callosum.
