Ophthalmoscope

rdfs:comment

Ophthalmoscope (or funduscope) is an instrument used to examine the eye. Its use is crucial in determining the health of the retina and the vitreous humor. In patients with headaches, the finding of swollen optic discs, or papilledema, on ophthalmoscopy is a key sign, as this indicates raised intracranial pressure (ICP) which could be due to hydrocephalus, benign intracranial hypertension (aka pseudotumor cerebri) or brain tumor, amongst other conditions. Cupped optic discs are seen in glaucoma. The ophthalmoscope is a miscellaneous item in Fallout 3 and Fallout: New Vegas.

Ophthalmoscope (or funduscope) is an instrument used to examine the eye. Its use is crucial in determining the health of the retina and the vitreous humor. In patients with headaches, the finding of swollen optic discs, or papilledema, on ophthalmoscopy is a key sign, as this indicates raised intracranial pressure (ICP) which could be due to hydrocephalus, benign intracranial hypertension (aka pseudotumor cerebri) or brain tumor, amongst other conditions. Cupped optic discs are seen in glaucoma. In patients with diabetes mellitus, regular ophthalmoscopic eye examinations (once every 6 months to 1 year) are important to screen for diabetic retinopathy as visual loss due to diabetes can be prevented by retinal laser treatment if retinopathy is spotted early. In arterial hypertension, hypertensive changes of the retina closely mimic those in the brain, and may predict cerebrovascular accidents (strokes). Numerous companies manufacture direct ophthalmoscopes, including HEINE, Welch Allyn, Riester and Keeler. Ophthalmoscopes are often sold with otoscopes as a diagnostic set. The ophthalmoscope is a miscellaneous item in Fallout 3 and Fallout: New Vegas.
