Abstract

Folding of the choroid, Bruchs membrane, and the overlying retina may occur in a variety of ocular and orbital diseases and after certain surgical procedures. A 34-year-old man experienced the decreased visual acuity and the protrusion and displacement in the right eye for at least 4 years. The protrusion of the patient was 13mm in the right eye and 6mm in the left eye with the aid of Hertels exophthalmometer. The right eye appeared downward deviation about 15 prism. The tumor located outside the muscle cone in the computed tomography and ultrasonography seemed to make the large choroidal folds involving the macula region. The retinal pigment epithelial atrophy was noted along long-standing choroidal folds. The tumor was removed by the lateral orbitotomy. The size of tumor was 20 x 15x 10mm. The postoperative protrusion was 6mm in the both eye. After removal of tumor, changes in the corneal refraction, visual acuity, and choroidal folds with the retinal pigment epithelial atrophy did not occur in comparison with the preoperative state.
