Discoid lupus erythematosus (DLE) is a chronic skin disease that may affect the eyelids. Unless suspected, these lid lesions may resemble chronic blepharitis and persist for years. We present the clinicopathologic features of DLE from the lids of seven patients, electron microscopic features of one case, and a review of 31 previously reported cases.
We performed a histopathologic and immunohistochemical study of eyes obtained at autopsy of an 84-year-old man from a family with X-linked cone degeneration in which affected members have a 6.5-kilobase deletion in the red cone pigment gene. At his most recent ocular examination, at age 71 years, this patient had had a visual acuity of 20/200 OU, fundus(More)
PURPOSE To determine the biocompatibility of a new wireless intraocular pressure (IOP) transducer (WIT) in rabbit eyes and to correlate its measurements with other pressure-measuring devices. METHODS The WIT is a ring-shaped intraocular device that allows wireless IOP measurements through radiofrequency. It was implanted into six eyes of New Zealand White(More)
Vasoactive intestinal polypeptide (VIP) is a biologically active neuropeptide found in both the peripheral and the central nervous systems. Previous studies have shown that VIP-like immunoreactive nerves are present in the uveal tissues of the human eye. The distribution of VIP-like immunoreactivity of the human lacrimal gland and sphenopalatine ganglion(More)
Lesions of the retina, choroid, and sclera were created in the proptosed eye of the rabbit with the use of focused ultrasound at 9.8 MHz. Exposure levels greatly exceeding those encountered in diagnostic systems were required. Histological examination of selected tissue samples, analysis of lesion-producing exposures, and lesion size variations suggest that(More)
Intraocular medulloepithelioma (IO MEPL) is an uncommon embryonal neuroepithelial neoplasm of the eye. These ocular neoplasms have been compared with intracranial medulloepitheliomas or other histologic variants of CNS embryonal tumor with multilayered rosettes (CNS ETMR) due to their morphological mimicry. We performed comprehensive molecular analysis to(More)
CT and MR imaging are the modalities of choice in the assessment of orbital neoplasia. When combined with the clinical history and examination, radiologic imaging can provide valuable information regarding tumor diagnosis. Imaging studies thus enable the clinician to delineate the extent of disease and plan the surgical approach for biopsy or excision. In(More)
Neurogenic monocular nasal field defects respecting the vertical midline are quite uncommon. We report a case of a unilateral nasal hemianopia that was caused by compression of the left optic nerve by a sphenoid wing meningioma. Histological examination revealed that the pathology of the meningioma was consistent with that of an atypical meningioma, which(More)
Bing-Neel syndrome (BNS) is defined as intracranial involvement of Waldenström macroglobulinemia (WM). Few cases of orbital involvement have been reported. A 51-year-old man with a history of WM developed bilateral orbitopathy and optic neuropathy. Orbital biopsy, cerebrospinal fluid studies, and neuroimaging confirmed the diagnosis of BNS involving the(More)

Abstract The biocompatibility and antibacterial properties of N,N-hexyl,methyl-polyethylenimine (HMPEI) covalently attached to the Boston Keratoprosthesis (B-KPro) materials was evaluated. By means of confocal and electron microscopies, we(More)
