Partial closure of right superior orbital fissure with narrow optic foramenin

Author(s): Shankreppa Doddappa Desai* and Sunkeswari Sreepadma

Superior orbital fissure is situated between the greater and lesser wings of sphenoid, with the optic strut at its superomedial margin. It lies between the roof and lateral wall of the orbit. The superior orbital fissure is divided by the common tendinous origin of the recti muscles. Compression of the neurovascular structures due to variations in the superior orbital fissure may result in signs and symptoms due to involvement of cranial nerves III, IV, V1, and VI. We report here a variation of the superior orbital fissure. Superior orbital fissure was partly closed by a thin plate of bone on the right side, and on the same side there was a narrow optic foramen. It is essential to know such variations to understand the underlying cause for the clinical conditions and operate in those areas.
