摘要:

PurposeTo review the underlying causes, diagnostic issues, and treatment of hemifacial spasm, with emphasis on advanced MRI techniques.MethodsBrief technical note.ResultsHigh-resolution T1- and T2-weighted spin-echo and/or gradient echo imaging of the posterior fossa should be performed with the use of intravenous gadolinium for maximum contrast between CSF, vessel, and nerve. Magnetic resonance angiography is often useful, and new state-of-the-art sequences provide more detail.ConclusionsAs MRI techniques improve, diagnosis and treatment of patients with hemifacial spasm will become easier. Ophthalmologists should be aware of these new magnetic resonance techniques.

摘要:

PurposeIdiopathic congenital retraction of the lower eyelid is rare. To further define the clinical features of this condition, we describe two new cases.MethodsRetrospective chart review.ResultsIn both cases, eye movements were restricted ipsilaterally and the condition was nonprogressive. CT scans showed mildly enlarged inferior and medial rectus muscles in one patient and normal muscles in the other. All other orbital structures were normal.ConclusionsNo definite cause for the lower eyelid retraction could be found, but it appeared to be related to a tight inferior rectus muscle. These patients may represent a variant of ocular fibrosis syndrome.

摘要:

PurposeTo report the results of the surgical repair of lower eyelid reverse ptosis.MethodsRetrospective case series. Eight patients ranging in age from 31 to 77 years underwent surgical repair of lower eyelid reverse ptosis. The pupillary axis of the affected eye(s) in each patient was obscured in downgaze, interfering with reading. The lower eyelid reverse ptosis resulted from involutional changes in 3 patients, previous orbital decompression in 3 patients, multiple prior retinal and extraocular muscle operations in 1 patient, and previous orbital floor fracture and repair in 1 patient. Transcutaneous advancement of the lower eyelid retractors was performed in 12 eyelids of the 8 patients.ResultsThe mean preoperative vertical eyelid fissure was 6.2 mm (median, 6 mm; range, 3–9 mm), increasing after surgery to a mean of 7.7 mm (median, 8 mm; range, 5–11 mm). The mean preoperative distance between the central light reflex and the lower eyelid margin was 1.7 mm (median, 1.25 mm; range, 1–4 mm); this distance increased to a mean of 3.3 mm (median, 3.25 mm; range, 2.5–4.5 mm) after surgery. Symptoms improved in all patients, and there were no perioperative complications. Follow-up intervals ranged from 2 months to 24 months (mean, 9 months; median, 13 months).ConclusionsAnalogous to upper eyelid ptosis repair by advancement of the levator aponeurosis, lower eyelid reverse ptosis may be corrected effectively and safely by advancing the lower eyelid retractors.

摘要:

PurposeTo report orbital metastasis as the presenting sign of a nonpalpable breast carcinoma in a 61-year-old woman.MethodsCase report and literature review.ResultsA uterine metastasis of unknown origin found 11 years prior was retrospectively identified as having the same histopathology as the breast and orbit tumors. Eight years after her orbital presentation, the patient was diagnosed with and underwent resection of a metastatic adenocarcinoma of the colon, consistent with lobular adenocarcinoma of the breast.ConclusionsThis is a rare case of an orbital metastatic adenocarcinoma preceding the diagnosis of a nonpalpable primary breast carcinoma.
