A patient with a coup de sabre lesion of the forehead developed progressive ipsilateral limitation of ocular motility, primarily involving adduction and depression. Investigation disclosed no other explanation for the ocular motility disturbance, which we suspect represents restrictive myopathy maximally involving ocular muscles immediately subjacent to the area of linear scleroderma.
Six bilateral and two unilateral cases of dysthyroid optic neuropathy are presented. These patients underwent inferior orbital decompression through a lower-lid approach, with removal of the orbital floor and underlying antral mucosa. They demonstrated improved visual function as evidenced by visual acuity, visual fields, or visually evoked potentials.
A technique of inferior orbital decompression for thyroid ophthalmopathy is described. The orbital floor is exposed through a lower eyelid incision, and completely removed while preserving the infraorbital nerve and vessels. A central strip of periorbita is retained under the globe for support. The amount of decompression averages 4 mm and ranges from 2 to 6 mm, depending on the amount of inflammatory residue and extraocular muscle enlargement.
A 12-year-old girl and a 30-year-old woman had bilateral optic disk hypoplasia and bitemporal hemianopia. By using computed axial tomography on our patients, we demonstrated the absence of the septum pellucidum, which confirmed the diagnosis of septo-optic dysplasia, or the de Morsier syndrome.
We reviewed eight cases of congenital homonymous hemianopia to emphasize the features that may help the clinician to diagnose a congenital disease. The patients were usually unaware of the visual field defect. The hemianopia was usually congruous when incomplete and the opticokinetic nystagmus had a normal pattern. Associated congenital ocular and neurologic abnormalities were common. Clinically recognizable atrophy or hypoplasia of the optic disk was found in all but one of the patients. There was often a history of neonatal or gestational difficulties followed by emotional, behavioral, and learning problems without mental retardation.
Disk swelling in patients with hypoparathyroidism has often been attributed to papilledema but rarely to optic neuritis. Although we are reporting a patient with hypoparathyroidism in whom optic neuritis developed, a causal relationship is not yet clear. The patient may have had ischemic optic neuropathy concomitant with hypoparathyroidism or caused by tetanic vasospasm or calcification of optic nerve nutrient vessels.
