Melanocytoma of the optic nerve head - a diagnostic dilemma
The clinical features, autofluorescence, B-scan ultrasonography, optical coherence tomography and fluorescein angiography of the lesion were described. Multiple investigation modalities are needed to confirm the benign nature of the lesion. Careful evaluation and follow-up is crucial to avoid misdiagnosis and erroneous management.

متن کاملClinicopathological findings in a growing optic nerve melanocytoma.
We present an unusual case of a melanocytoma of the optic disc that showed documented progressive growth over a period of six years. It reached the largest size of any reported optic nerve melanocytoma and the eye was enucleated because of the possibility of malignant degeneration. Optic nerve melanocytomas are locally invasive but are not known to undergo transformation into malignant melanoma...
متن کاملOptic Nerve: Clinical Examination
Optic nerve-head examination is probably the most important step in the diagnosis of glaucoma and is also extremely important in monitoring patients with established glaucoma. There are several ways to clinically examine the optic nerve head, including direct ophthalmoscopy, indirect ophthalmoscopy, and slit lamp biomicroscopy with contact lenses (such as a Goldman lens), handheld lenses (such ...
متن کاملGeneralized periodic discharges: Pathophysiology and clinical considerations
Generalized periodic discharges (GPDs) are commonly encountered in metabolic encephalopathy and cerebral hypoxia/ischemia. The clinical significance of this EEG pattern is indistinct, and it is unclear whether treatment with antiepileptic drugs is beneficial. In this study, we discuss potential pathophysiological mechanisms. Based on the literature, supplemented with simulations in a minimal co...
