[Optic nerve drusen and deep visual fields defects].
PURPOSE Optic nerve drusen needs to be included in the differential diagnosis of pseudopapilledema. As the identification of this entity by funduscopy may be difficult, ultrasonography has thus become the gold standard for its diagnosis. Severe optic nerve drusen has been correlated with a reduction of the nerve fiber layer measured by optic coherence tomography and with the presence of serious...
متن کاملDecreased visual acuity from optic disc drusen.
Although visual field defects occur commonly from optic disc drusen, reduction in visual acuity is rare. We describe four patients with reduced visual acuity and one with visual field constriction to the point of legal blindness that resulted from optic disc drusen. The acute episodic and stepwise nature of visual loss in some of the cases in our series suggests a vascular mechanism. Reduced vi...
متن کاملOptic disk drusen.
Optic disk drusen occur in 3.4 to 24 per 1,000 population and are bilateral in approximately 75%. Disturbance in the axonal metabolism in the presence of a small scleral canal--regardless of eyelength--is considered responsible for the development. The drusen increase in size, becoming more visible with age due to continuing calcium apposition, and they are associated with visual field defects ...
متن کاملRadial optic neurotomy as a treatment for anterior ischemic optic neuropathy secondary to optic disc drusen
IMPORTANCE Radial optic neurotomy (RON) was first described by Opremcak as a treatment for patients with central retinal vein occlusion (CRVO). The most common cause of visual loss in patients with optic disc drusen is nonarteritic anterior ischemic optic neuropathy (NAION). The pathogenesis of nonarteritic anterior ischemic optic neuropathy associated with optic disc drusen is assumed to be si...
متن کامل[Optic Disc Drusen and their Complications].
UNLABELLED The aim of the study was to analyze the group of patients with optic disc drusen focusing on possible complications of this disease. MATERIAL AND METHODS In our group of patients, we examined 46 eyes of 23 patients with the suspicion of optic disc drusen during the period from May 2013 until January 2014. In all adult patients, we examined the anterior and posterior segment of the ...
متن کاملOptic nerve head drusen and glaucoma.
The simultaneous occurrence of both optic nerve head drusen and glaucoma may make it difficult to evaluate visual field defects and the appearance of the optic nerve head. We saw five patients with both conditions, of whom four had pigmentary glaucoma or pigmentary dispersion syndrome. Drusen do not preclude the development of cupping, and they make it difficult to interpret its significance. M...
