Gliomas of the anterior visual pathway are rare orbital lesions accounting for 65% of all intrinsic optic nerve tumors. These lesions occur principally among children in the first decade of life. They appear to be true neoplasms that characteristically show early growth, followed by stability in many patients. Visual prognosis is fair, and the outlook for(More)
Meningiomas are benign neoplastic lesions arising from meningothelial cells of the meninges. Primary orbital meningiomas, originating in the optic nerve sheath, represent 1-2% of all meningiomas, and are the second most common optic nerve tumor after gliomas. They primarily affect middle-aged adults. Patients typically present with visual loss, frequently(More)
The authors review their long-term results and complications with the use of botulinum A toxin in the treatment of facial dystonias. Two hundred thirty-two patients in three diagnostic groups--essential blepharospasm, hemifacial spasm, and Meige's syndrome--were treated with botulinum A toxin. A total of 1044 treatments were given over a 4-year period. A(More)
Thirty canaliculi of 18 patients with complete or nearly complete canalicular obstruction were subjected to laser canaliculoplasty as a substitute for the standard Jones-type bypass conduct. Etiologies for the obstruction included congenital lacrimal system atresia, eyelid trauma, scarring following previous lacrimal surgery, and chronic inflammatory(More)
In 43 patients (81 eyes) with blepharospasm resistant to other forms of therapy, 149 outpatient injections of botulinum A toxin were given into the orbicularis oculi muscle. Subsequent follow-up periods ranged from ten to 210 days. Orbicularis oculi spasm, eyelid forced closure, and eyebrow spasm all decreased substantially over the first ten days following(More)
Epibulbar osseous choristoma is a choristomatous lesion of the conjunctiva containing bone. Originally called epibulbar osteoma, this lesion was first described by von Graefe in 1863. We discuss a case of a 4-year-old patient who presented with an epibulbar lesion consistent histopathologically with an epibulbar osseous choristoma, and report a review of(More)
Fifty patients received a coralline hydroxyapatite sphere as a buried integrated ocular implant after enucleation or evisceration surgery. The surgical technique is described and the results discussed. All patients obtained final prosthetic motility superior to that possible with simple spherical methylmethacrylate implants. After a follow-up of 2 to 27(More)
Optic nerve gliomas are benign astrocytic neoplasms that primarily affect children. The ultimate prognosis for vision is poor. For lesions confined to the optic nerves, long-term survival is excellent, but with involvement of the chiasm and especially of the hypothalamus or third ventricle, prognosis falls significantly. For this group, no form of therapy(More)
Photoradiation therapy (PRT) is a new technique that is currently under investigation for the treatment of a variety of solid malignant tumors. The technique involves systemic administration of hematoporphyrin derivative (HpD), a photosensitizing compound that is preferentially retained by malignant cells and photoactivation of the neoplasm with red light(More)
Since its introduction into clinical medicine in 1980, botulinum toxin has become a major therapeutic drug with applications valuable to many medical sub-specialties. Its use was spearheaded in ophthalmology where its potential applications have expanded to cover a broad range of visually related disorders. These include dystonic movement disorders,(More)
