Imaging Methods in the Diagnosis of Optic Disc Drusen

open access: yesTürk Oftalmoloji Dergisi, 2016
Optic disc drusen (ODD) are benign congenital anomalies of the optic nerve characterized by calcified hyaline bodies. While superficial drusen can be diagnosed easily during fundus examination, detecting buried drusen requires the use of additional ...

Evaluation of retinal nerve fiber layer thickness in a patient with bilateral optic disc drusen

open access: yesRevista Brasileira de Oftalmologia, 2015
Optic disc drusen (ODD) is the accumulations of calcified hyaline-like material within the substance of the optic nerve head. Optic disc drusen, especially if it is bilateral, may mimic the clinical presentation of papilledema.

Assembly and proving of a wave front sensing confocal Scanning Laser Ophthalmoscope [PDF]

open access: yes, 2007
Confocal Scanning Laser Ophthalmoscopy is used to image the fundus of the living eye. In theory, this technique can be used to observe single cells of the retina. Unfortunately, vision of most eyes is decreased by higher-order aberrations, that cannot be
