Nasolacrimal duct obstruction following transantral-ethmoidal orbital decompression.

Of 200 patients undergoing bilateral transantral-ethmoidal orbital decompression for Graves' ophthalmopathy, nine suffered symptomatic postoperative obstruction of the lower nasolacrimal excretory system. Five of the nine patients had persistent symptoms of epiphora or repeated episodes of dacryocystitis that necessitated dacryocystorhinostomy. Dacryocystorhinostomy relieved symptoms and objective evidence of obstruction in these five patients. We believe that nasolacrimal duct obstruction occurred in these patients as a complication of nasoantral window construction.

Cavernous hemangioma of the retina.

Cavernous hemangioma of the retina is recognized as a distinct clinical entity. Although neurocutaneous findings are sometimes associated with these retinal tumors, in most of the cases reported to date, systemic features have not been described. This report describes two patients with cavernous hemangioma of the retina. One had neurologic symptoms and signs that were highly suggestive of a hemangioma of the brain stem, and the other had major congenital cardiovascular anomalies. During a five-year interval, the second patient had spontaneous incomplete sclerosis of the retinal hemangioma.

The ocular manifestations of Behçet's disease.

Of 32 patients with Behçet's disease, 21 had uveitis. The uveitis was seldom the initial manifestation of systemic disease, but once established, it tended to become chronic and bilateral, involving the anterior and posterior segments. Hypopyon was a relatively uncommon occurrence in this series. All patients with uveal inflammation had obvious cellular reactions within the vitreous body. Other posterior segment manifestations of the disease included localized retinal edema, macular edema, disc edema, retinal pigmentary changes, and accumulation of exudative material in the deep retina. One patient developed a necrotizing retinitis with deep retinal exudation and subsequent retinal detachment. Occlusions of retinal vessels were common. Neuro-ophthalmologic manifestations of Behçet's disease included cranial nerve palsies, a homonymous hemianopic field defect, and papillitis.
