Ophthalmologic findings and long-term course in patients with neurofibromatosis type 2


Bosch, M M; Boltshauser, E; Harpes, P; Landau, K (2006). Ophthalmologic findings and long-term course in patients with neurofibromatosis type 2. American Journal of Ophthalmology, 141(6):1068-1077.

Abstract

PURPOSE: To evaluate ophthalmologic findings and long-term course in patients with neurofibromatosis type 2 (NF2). DESIGN: Retrospective observational case series. METHODS: SETTING: Single-center institutional practice. STUDY POPULATION: Thirty referred patients with NF2 were enrolled from 1991 to 2003 and underwent at least one thorough neuroophthalmologic examination. Follow-up of 23 patients ranged from 4.3 to 12.5 years. MAIN OUTCOME MEASURES: Visual function, structural ocular abnormalities, onset and type of presenting NF2-related symptoms, and number of central nervous system tumors. RESULTS: Initial symptoms for patients with early-onset NF2 mostly comprised ophthalmologic symptoms (n = 7) and lower motor neuron extremity weakness (n = 6), as opposed to eighth nerve impairment (n = 11) in late disease onset. NF2-specific ocular findings were noted in 83% of all patients (94% childhood onset; 67% adult onset): 67% had cataracts, 40% epiretinal membranes, 3% hamartoma, 13% disk gliomas, and 27% optic nerve sheath meningiomas. Only 14% in the childhood-onset group-as opposed to 78% in the adult-onset group-sustained visual acuity of 1.0 in both eyes at final examination. Significantly more patients with early onset of symptoms developed multiple central nervous system tumors (P = .004) and showed a higher amount of NF2-specific findings (P = .015). CONCLUSIONS: Initial manifestations of NF2 differ between children and adults. NF2-specific ophthalmologic findings can help establish the diagnosis. Symptom onset at a young age is clearly a risk factor for marked disease progression. These patients should be carefully followed because survival rates have increased, and vision becomes increasingly important as the disease progresses.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
