[Confocal scanning laser retinal tomography in study of 3-D topography of the optic disk in patients with papilledema].
Confocal scanning laser tomography (CSLT) giver the opportunity to describe stereometric parameters of the optic disk in patients with different stages of papilledema. CSLT of the optic disk (Heidelberg Retina Tomograph II) was performed in 20 healthy volunteers (40 eyes) and in 85 patients with papilledema caused by cerebral tumors (8 eyes without papilledema, 52 eyes with early, 38 with moderate and 56 with severe stage of papilledema, and 9 with chronic papilledema and optic atrophy). Rim volume (RV) and disk area (DA) were measured. CSLT was performed during postoperative follow-up in 40 patients. The difference in RV (p < 0.01) and DA (p < 0.01) between normal optic disk and optic disk with early and moderate edema, and optic disk with severe edema, was significant. Stereometric parameters of optic disks measured by CSLT provide objective quantitative assessment of papilledema in patients with cerebral tumors. CSLT is especially valuable in monitoring of papilledema.
