1/532. Bilateral optic disk edema caused by sarcoidosis mimicking pseudotumor cerebri.PURPOSE: To present a case of retrobulbar optic nerve and chiasm sarcoidosis that mimicked pseudotumor cerebri. methods: A 34-year-old, thin, black woman presented with transient visual obscurations, normal visual acuity, bilateral optic disk edema, and enlarged blind spots. Clinical, medical, and radiologic evaluations were consistent with pseudotumor cerebri. The patient improved while taking acetazolamide, but 6 months later her symptoms worsened. neuroimaging disclosed enhancement of the optic nerve and chiasm. RESULTS: Despite administration of intravenous corticosteroids, the patient's vision worsened. Bilateral optic nerve sheath fenestrations were performed, and pathology disclosed sarcoidosis. CONCLUSION: sarcoidosis of the optic nerves and chiasm may mimic pseudotumor cerebri.- - - - - - - - - - ranking = 1keywords = optic disk edema, disk edema, optic disk, optic, disk, edema (Clic here for more details about this article) |
2/532. papilledema associated with a sacral intraspinal cyst.A rare case of papilledema associated with a large sacral intraspinal cyst is described in a 34-year-old male. Symptoms were aggravated by heavy work and consisted of low back pain, headache, dizziness and episodic vomiting. papilledema was observed on ophthalmological examination. A valvular mechanism was found to exist between the normal spinal sac and the huge sacral cyst. Division of the valvular fistula combined with a dural plastic operation brought complete relief of all symptoms.- - - - - - - - - - ranking = 0.28111428798105keywords = papilledema, edema (Clic here for more details about this article) |
3/532. color Doppler image of central retinal artery of eyes with an intraconal mass.PURPOSE: Retinal ischemia secondary to hypoperfusion of the central retinal artery is recognized as one factor that may contribute to the development of loss of vision in eyes with intraorbital tumors. We study intraorbital tumors which produce motility disturbances and visual problems by color Doppler imaging to evaluate this factor. methods: We examined the central retinal artery velocities of 3 patients with disc edema caused by intraconal masses (2 cavernous hemangiomas and 1 presumed optic nerve glioma) via color Doppler imaging. RESULTS: The time-velocity waveform demonstrated abnormally high vascular resistance in the central retinal artery of all affected eyes in the primary position compared with the normal waveform seen in the other eyes. We compared the pulsatility index of eyes with an intraconal mass and contralateral, control eyes using Student's t test for paired samples and significant differences were noted between both groups (p< 0.01). CONCLUSIONS: Intraconal tumors could produce increased pressure in the optic nerve sheath and the optic nerve tissue which could be associated with impaired retinal and optic nerve blood flow and the subsequent amaurosis encountered with intraorbital tumors.- - - - - - - - - - ranking = 0.0064844179130509keywords = optic, edema (Clic here for more details about this article) |
4/532. Interstitial nephritis and uveitis syndrome presenting with bilateral optic disk edema.PURPOSE: To report a rare presentation of the tubulointerstitial nephritis and uveitis syndrome. METHOD: Case report. A 34-year-old woman underwent extensive clinical and laboratory evaluation of bilateral intermediate uveitis and optic nerve edema. RESULTS: Laboratory evaluation and nephrology consultation led to a diagnosis of tubulointerstitial nephritis. The condition resolved with the use of topical and systemic corticosteroids and the discontinuation of ibuprofen. CONCLUSIONS: Tubulointerstitial nephritis and uveitis syndrome is uncommon. It may present with anterior or intermediate uveitis. Chronic intermediate uveitis can cause optic nerve and macular edema. A thorough medical evaluation of any patient presenting with uveitis and systemic disease is essential to the diagnosis and management of uveitis.- - - - - - - - - - ranking = 0.02654811840492keywords = optic disk, optic, disk, edema (Clic here for more details about this article) |
5/532. Unilateral papilledema after bone marrow transplantation.We describe a patient who developed unilateral papilledema after allogeneic BMT. This is a rare manifestation of pseudotumor cerebri, which results from elevated intracranial pressure caused by cyclosporin A. The papilledema usually involves the fundi bilaterally, but unilateral involvement has been described. Congenital anomalies, compression and adhesion of the optic nerve sheath are its causes. In this patient, the right optic fundus was spared although leukemic infiltration was present on this side and high-dose irradiation (72 Gy) was given. Although papilledema is a sensitive marker of elevated intracranial pressure, this sign may be masked by constriction of the optic sheath in patients who suffer from leukemic infiltration of the central nervous system and receive high doses of cranial irradiation.- - - - - - - - - - ranking = 1.9713273379871keywords = papilledema, optic, edema (Clic here for more details about this article) |
6/532. pseudotumor cerebri in children receiving recombinant human growth hormone.PURPOSE: This article represents the first report in the ophthalmology literature of an association between pseudotumor cerebri (PTC) and recombinant human growth hormone (rhGH). DESIGN: Noncomparative case series. PARTICIPANTS: Three children receiving rhGH for short stature with turner syndrome, Jeune syndrome, or down syndrome. methods: Children underwent full ocular examination. After papilledema was identified, patients underwent lumbar puncture and imaging with either magnetic resonance imaging or computerized tomography. Treatment was under the guidance of the primary physician or neurosurgeon. The rhGH was discontinued in all children. MAIN OUTCOME MEASURES: visual acuity and evaluation of the optic nerve for resolution of papilledema were followed at each examination. RESULTS: In all three cases, papilledema resolved with the cessation of rhGH, and treatment with acetazolamide or prednisone. visual acuity was unchanged in case 1, decreased by two to three lines in case 2, and was inconsistent in case 3. One child (case 2) required a ventriculoperitoneal shunt for persistent elevation of intracranial pressure. CONCLUSION: There appears to be a causal relationship between the initiation of rhGH with the development of PTC. Children should have a complete ophthalmic evaluation if they report headache or visual disturbances. Baseline examination with routine follow-up should be instituted when children cannot adequately communicate.- - - - - - - - - - ranking = 0.8443940700283keywords = papilledema, optic, edema (Clic here for more details about this article) |
7/532. Central retinal vein occlusion during remission of ulcerative colitis.BACKGROUND: Retinal vascular disease is a rare complication of ulcerative colitis. CASE: We report a patient who developed unilateral nonischemic central retinal vein occlusion (CRVO) (papillophlebitis) without any other retinal vascular disease during remission of ulcerative colitis. OBSERVATIONS: The best-corrected visual acuities were 1.5 OD and 0.7 OS. Dilated and tortuous retinal veins and retinal bleeding were seen in the left eye. macular edema and leakage from the papilla and the retinal veins of the left eye were evident on fluorescein angiography. After increased dosage of systemic prednisolone was prescribed, the retinal vascular changes resulting from CRVO (papillophlebitis) in the left eye gradually abated. CONCLUSIONS: Retinal vascular diseases should be monitored during both remission and activation of intestinal symptoms of ulcerative colitis.- - - - - - - - - - ranking = 3.7370386433008E-5keywords = edema (Clic here for more details about this article) |
8/532. Optic neuropathy following amiodarone therapy.Ocular changes during treatment with amiodarone are almost universal but are rarely serious. In this article we describe three patients from a single electrophysiology practice in whom optic neuropathy developed during treatment with amiodarone. All three patients were more than 65 years of age. The doses of amiodarone ranged from 100 to 400 mg/day, and the time intervals between the initiation of the amiodarone therapy and the appearance of first symptoms of optic neuropathy were 5 to 19 months. Two patients had bilateral involvement, and one had only unilateral involvement. Whether this result was due solely to amiodarone therapy, to the underlying poor health of these patients, or to the combination of these two factors is uncertain. These findings prompt us to recommend that all patients who receive amiodarone undergo complete ophthalmologic examinations, including careful evaluation of the ocular fundus regularly during such therapy. No randomized study had been undertaken to determine the true incidence of complications associated with this medication.- - - - - - - - - - ranking = 0.0032235237633089keywords = optic (Clic here for more details about this article) |
9/532. Papilloedema secondary to acute purulent sinusitis.Upper respiratory tract infections and sinusitis are common, but intracranial complications of sinusitis are rare in children and are often clinically unremarkable. Papilloedema secondary to purulent sinusitis is a complication previously not reported. We report two cases to highlight atypical manifestations of sinusitis in children.- - - - - - - - - - ranking = 0.00018685193216504keywords = edema (Clic here for more details about this article) |
10/532. Hypotensive ischemic optic neuropathy and peritoneal dialysis.PURPOSE: To report anterior ischemic optic neuropathy associated with systemic hypotension in a patient undergoing continuous ambulatory peritoneal dialysis. methods: Case report. A 58-year-old man undergoing continuous ambulatory peritoneal dialysis developed painless blurred vision in both eyes and bilateral optic disk swelling with an altitudinal field defect in the left eye. Twenty-four-hour ambulatory blood pressure monitoring was requested in addition to other routine investigations. RESULTS: Routine blood pressure measurement in the clinic was 130/86 mm Hg, but ambulatory blood pressure monitoring demonstrated pronounced early morning hypotension with individual readings as low as 91/41 mm Hg. CONCLUSIONS: renal dialysis can render patients hypotensive, and this may be associated with anterior ischemic optic neuropathy. The overnight drop in blood pressure may not be appreciated with routine blood pressure measurement. Therefore, 24-hour ambulatory blood pressure monitoring should be considered when investigating patients with suspected anterior ischemic optic neuropathy who are undergoing renal replacement.- - - - - - - - - - ranking = 0.017057426252335keywords = optic disk, optic, disk (Clic here for more details about this article) |
