摘要:

Computed tomographic and magnetic resonance imaging scans have breathed new life into anatomic studies and clinical correlations of structure and function of the eyelid and orbit. Hydroxyapatite orbital implants promise better cosmetic results, but we are only beginning to understand how they are integrated within orbital tissues and how to enhance this integration. Three more cases of phacomatous choristoma, a rare tumor of lens anlage, have been studied, and one has been characterized by immunohistochemical staining. Adenoid cystic carcinoma is the most common epithelial malignancy of the lacrimal gland, and is associated with a high mortality, especially when a basaloid pattern is prominent. Complete excision with radiation may have a higher cure rate. Mucormycosis, a devastating complication of diabetes mellitus and other chronic diseases, can cause an orbital apex syndrome, with ophthalmoplegia and decreased vision. Fine-needle biopsy can help to establish the diagnosis.

摘要:

Significant contributions to understanding the epidemiologic characteristics of Craves' ophthalmopathy and to improving the management of individual patients have been provided by reports published within the past year. Several studies have shown a strong association between tobacco smoking and Craves' ophthalmopathy. It is not yet known whether cessation of smoking by patients with Graves' hyperthyroidism will decrease the risk for development or progression of ophthalmopathy. However, we discuss with patients the findings of current studies and indicate that cessation of smoking may be helpful. Treatment of hyperthyroidism with iodine-131 solution has been suggested to increase the risk for ophthalmopathy, but that view has not been accepted by many physicians. Several improvements in current methods for managing ophthalmopathy are reviewed.

摘要:

Appropriate axial or coronal computed x-ray tomography is the most inexpensive method to reliably supply detail in orbital disease. Magnetic resonance imaging can provide additional information and may be characteristic in some conditions. Magnetic resonance imaging is imperative for detailed imaging of disease at the orbital apex, optic canal, or chiasm. Color-coded Doppler ultrasonography allows examination of physiological blood flow within orbital vasculature and recent reports have reported the changes of flow in various orbital diseases. Limited results with computed tomographic or video-radiographic investigation of lacrimal outflow obstruction have been presented in several articles, although it remains doubtful whether these techniques are superior to the cheaper, more readily available, conventional macrodacryocysto-graphy. Endoscopy of the lacrimal drainage system is proving to be an interesting research tool, but is of uncertain applicability in the treatment of disease.

摘要:

Several notable contributions to the literature in the field of congenital and childhood orbital and oculoplastic disorders are reviewed. Nasolacrimal obstruction in childhood is common, and the management, ranging from conservative treatment to probing and placement of stents, is discussed. A wide range of other topics are presented including canalicular lacerations, congenital ptosis, anatomy, battered-child syndrome, surgical treatment of capillary hemangioma, and laser therapy for facial port-wine stains. Facial port-wine-stain vascular anomalies are associated with significant psychosocial morbidity. With the flash lamp-pumped pulsed-dye laser, individuals affected with these birthmarks can be treated with very impressive results.

摘要:

The lacrimal drainage system includes the nasolacrimal duct, lacrimal sac, and canaliculi. Stenosis or obstruction at any portion of the lacrimal drainage system or an impaired lacrimal pump may cause bothersome epiphora. Tear stasis may also be associated with ocular or adnexal infections. This article reviews the recent literature pertaining to anatomy and physiology, pathology, and clinical evaluation and treatment, as well as complications of lacrimal drainage-system disorders.

摘要:

During the past year, refinements in the treatment of many lid tumors have been proposed, including amyloidosis, Kaposi's sarcoma, sebaceous carcinoma, basal cell carcinoma, squamous cell carcinoma, and melanoma. There have also been innovative reports on eyelid reconstruction using hard-palate mucosal grafts, medial canthal reconstruction, lateral skin-muscle advancement flaps, and eyelid avulsions.

摘要:

Cosmetic blepharoplasty is performed in various subspecialties, therefore articles appear in the ophthalmic, plastic surgical, otolaryngologic, and dermatologic literature. We review the past year's articles regarding evaluation, technique, adjunctive procedures, and complications. As the various techniques of upper-eyelid and lower-eyelid blepharoplasty have taken their place in the armamentarium of the aesthetic surgeon, attention has turned toward adjunctive procedures to enhance the surgical result.
