Drusen - What Are They? They are simply small yellow or white deposits of lipid (a fatty compound)and calcium that build up in the Bruch's membrane of the eye. The Bruch's membrane is a layer of tissue underneath the retina.
Severe optic ner-. ve drusen has been correlated with a reduction of. the nerve fiber layer measured by optic coherence. tomography and with the presence of serious visual. field defects. To demonstrate the relationship bet-. ween extensive optic nerve drusen and visual field. defects. Method: A prospective observational study of the. visual fields of a series of 5 patients with severe. optic nerve drusen diagnosed by ultrasonography. Results: Visual field defects of widely differing. severity, from inferior nasal quadrant to severe. hemivisual field defects, were described in each. patient studied. Conclusions: Visual field defects of diverse seve-. rity are common in patients with deep optic nerve. drusen.
