Assessment of optic disc topography with scanning laser ophthalmoscope

Graefe's Archive for Clinical and Experimental Ophthalmology, 1993
Evaluation of the topography of the optic disc is of clinical importance to assess the degree of nerve damage. We conducted a study in 17 glaucomatous and 20 control subjects with a scanning laser ophthalmoscope (SLO; Rodenstock) and compared the results with those in conventional photographs. A tomographic image of the cup area in control subjects and

Optic disc topography and short-term increase in intraocular pressure

Graefe's Archive for Clinical and Experimental Ophthalmology, 1990
Intraocular pressure is intra- and interindividually inconstant. It is influenced by numerous ocular and general factors. We evaluated the question as to whether a short-term increase in intraocular pressure might change the two-dimensional topography of the optic nerve head.

Comparison of Optic Disc Topography Between Migrainous and Normal Subjects

Neuro-Ophthalmology, 2007
The purpose of this study was to compare the optic disc topography parameters in migrainous and normal subjects, by using Heidelberg retinal tomograph (HRT). The topographic optic disc parameters of 29 nonglaucomatous eyes of 29 cases with migraine and 29 eyes of 29 normal subjects were compared with nonparametric Mann Whitney U test. The mean cup area

Optic Disc Topography in Pseudopapilledema: A Comparison to Pseudotumor Cerebri

Journal of Neuro-Ophthalmology, 2001
To determine if confocal scanning laser (CSL) tomography can quantify optic disc topography in patients with pseudopapilledema (PP) and to contrast the regional topography of the optic disc in PP and pseudotumor cerebri (PTC).Three-dimensional optic disc images from 10 PP patients PP and 17 PTC patients were obtained using the Heidelberg Retinal ...

Optic Disc Topography Before and After Trabeculectomy in Advanced Glaucoma

Ophthalmic Surgery Lasers and Imaging Retina, 1996
* BACKGROUND AND OBJECTIVE: To analyze changes in the optic disc topography after filtration surgery. * PATIENTS AND METHODS. Laser scanning tomography was performed in 10 eyes of 9 patients (mean age 65-6 ± 8.1 years; age range 55 to 75 years) after a mean follow-up of 3.7 months, and in 8 eyes of 7 patients (mean age 63.1 ± 7.6 years; age ...

Differences in optic disc topography between black and white normal subjects

Ophthalmology, 2005
To determine if differences in optic disc topography exist between blacks and whites independent of racial differences in the area of the scleral canal.Cross-sectional observational study.A cohort of 146 eyes from black subjects and 97 eyes from white subjects without detectable ocular disease.Reliable bilateral images were obtained using a retinal ...

Change in Optic Disc Topography Associated with Diurnal Variation in Intraocular Pressure

Journal of Glaucoma, 1999
A case demonstrating significant changes in optic disc topography from variation in intraocular pressure (IOP) is demonstrated.Within a single 24-hour period, confocal scanning laser ophthalmoscopic images were obtained in the left eye of a patient during an IOP peak (60 mmHg) and during an IOP trough (18 mmHg).During an IOP trough, paired t tests ...
