There were multiple café au lait spots of more than 5 mm on the thorax, abdomen, and back skin (see Figure 1). Axillary and inguinal freckling was absent. The left side of the face had hypertrophic deformity due to the plexiform neurofibroma in the maxillary and mandibular region (see Figure 2C). The left upper eyelid had an S-shaped deformity and ptosis (see Figure 2A). On palpation it felt worm-like, consistent with the plexiform neurofibroma. There was marked proptosis and globe enlargement of the left eye (see Figure 2B and 3).The axial lengths of the right and left eye globe were 22.19 mm and 27.99 mm, respectively. The left eye corneal horizontal and vertical diameters were 13 mm each; the right eye corneal horizontal and vertical diameters were 11 mm each. The best corrected visual acuities of the right and left eye were 20/20 and 20/100, respectively. Extra ocular motility was normal. The right and left pupils were 3  mm and 6 mm, respectively. Afferent pupillary defect was noted in the left eye. Intraocular pressure (IOP) in the right eye and left eye were 12 mmHg and 28 mmHg, respectively. The right eye fundus examination was normal.
