The Spectrum of Ocular Manifestations in Patients with Waldenström's Macroglobulinemia.
2021
Purpose: To investigate the ocular manifestations in 91 Waldenstrom's macroglobulinemia (WM) patients.Methods: Retrospective, cross-sectional, observational analysis.Results: Ocular impairments, detected in 19 patients, included flame-shaped hemorrhages, venous sausaging, papilledema, macular detachments, or central retinal vein occlusion in 16 patients; paraproteinemic keratopathy in 2; and a CANOMAD syndrome in 1. Best-corrected visual acuity was ≥0.5 logMAR units in 11 of 38 eyes. Intraocular pressure was increased in seven eyes. Genetic analysis in seven patients showed a mutation in the MYD88 gene in six patients and a nonsense mutation in the CXCR4 gene in five patients. Plasmapheresi…
Optic Nerve Decompression Improves Hemodynamic Parameters in Papilledema
1993
Purpose: The purpose of this study is to examine changes in color Doppler imaging parameters before and after optic nerve sheath decompression (ONSD) for chronic papilledema caused by pseudotumor cerebri (PTC). Methods: Color Doppler imaging was performed within 48 hours before surgery and within 48 hours after the procedure using a color Doppler unit with a 7.5-MHz phased linear transducer. Pulsed Doppler spectrum analyses were recorded digitally on videotape from the ophthalmic, central retinal, and short posterior ciliary arteries, using a 0.4 × 0.6-mm sample volume. Results: Blood flow velocities in the ophthalmic, short posterior ciliary, and central retinal arteries of 24 eyes were si…
Occurrence of Cerebral Venous Sinus Thrombosis in Patients with Presumed Idiopathic Intracranial Hypertension
2005
Purpose To report the rate of occurrence of cerebral venous sinus thrombosis (CVST) in patients with presumed idiopathic intracranial hypertension (IIH). Design Retrospective chart review. Participants All patients diagnosed with papilledema from November 1, 2002, through October 31, 2003, at 3 tertiary care neuro-ophthalmology centers. Methods Consecutive patients with a diagnosis of papilledema from 3 tertiary care neuro-ophthalmology centers were identified. Patients with space-occupying lesions, hydrocephalus, or meningitis were excluded. The remaining patients were evaluated with lumbar puncture, magnetic resonance imaging (MRI), and magnetic resonance venography (MRV). Main Outcome Me…
Effects of Early Postfiltration Ocular Hypotony on Visual Acuity, Long-term Intraocular Pressure Control, and Posterior Segment Morphology
2001
Purpose To determine whether hypotony after filtration surgery has any influence on visual acuity and intraocular pressure (IOP) lowering. Patients and methods We prospectively investigated 43 eyes of 43 patients undergoing trabeculectomy without the use of antimetabolites for 12 months. Results The lowest postoperative IOP valued 4.9 +/- 3.6 mm Hg (range, 0-14 mm Hg). It correlated statistically significant with the IOP 6 weeks (P = 0.016), 6 months (P = 0.009), and 1 year after surgery (P = 0.027). Eyes with a deterioration of visual acuity 6 weeks after surgery had undergone a stronger postoperative hypotony (correlation with lowest postoperative IOP, P = 0.035). The mean period with an …
Ocular Changes in Patients With Mucopolysaccharidosis I Receiving Enzyme Replacement Therapy
2007
Objective To describe the progression of ocular changes in patients with mucopolysaccharidosis I receiving enzyme replacement therapy. Methods Three male and five female patients with mucopolysaccharidosis I were followed up for 4 years while undergoing enzyme replacement therapy with α-L-iduronidase (Aldurazyme). Visual acuity, corneal clouding, intraocular pressure, ophthalmoscopy, and optic disc measurements were performed yearly. Results Vision remained stable in 5 patients and deteriorated by at least 2 Snellen lines in 3 patients. Deterioration in 2 of these patients was related to progressive corneal clouding. Visual acuities improved in 1 patient after bilateral penetrating keratopl…
Subretinal neovascularization in anterior ischemic optic neuropathy.
1991
A 66-year-old man with typical anterior ischemic optic neuropathy in one eye suffered from edema of the optic disc without functional changes in the fellow eye. However, 7 months later, a reduction in visual acuity, a change in the visual field and a worsening of the contrast-sensitivity curve demonstrated the development of typical anterior ischemic optic neuropathy in this eye as well. After another 6-month period, in addition to these changes, an extensive subretinal neovascular membrane developed in the papillomacular area, which further reduced the patient's visual acuity and required treatment with laser photocoagulation. To our knowledge, this is the first case report of the occurren…
