[Use of scanning laser ophthalmoscope and scanning laser polarimeter in diagnosis and monitoring of early stages of primary open-angle glaucoma].

PURPOSE: To evaluate the usefulness of scanning laser ophthalmoscope (TopSS) and scanning laser polarimeter (GDx) in diagnosis and monitoring patients suspected of primary open angle glaucoma (POAG).

MATERIAL AND

METHODS

In eighty eyes of 40 patients, we performed TopSS, GDx and static perimetry (Octopus 123) in the time period of three years.

RESULTS

The GDx analysis showed progression of changes in the retinal fiber thickness in 28 (35%) eyes (p<0.05). In 18 eyes we found non-specific changes in GDx examinations, which were related to no glaucomatous reason. TopSS analysis of the optic nerve head revealed progression in c/d in 16 (20%) eyes (p<0.05). In seven eyes we detected changes in the visual field, which were more strongly connected with changes in TopSS than GDx.

CONCLUSIONS

1. The TopSS and GDx examinations enabled diagnosis and monitoring of early glaucomatous changes in the period of observation. 2. The GDx examination seems to be more sensitive, and TopSS more specific to glaucoma.
