| Summary: |
Purpose: The aim of
the study is an evaluation of applicability of selected
test in glaucoma diagnosis in a patient with optic disc
drusen.
Material and methods: The authors describe a case
of a patient examined for glaucoma because of an
increased intraocular pressure and deterioration of
vision. The optic disc drusen were found in the patient
by ophthalmoscopy and confirmed by ultrasonography. The
patient was examined by the scanning laser
ophthalmoscopy HRT, scanning laser polarymetry GDX,
retina thickness analysis RTA and determination of the
visual field.
Results: Results of diagnostic studies were
presented in the paper. The scanning laser
ophthalmoscopy did not evidence any presence of
glaucomatous cup in the optic nerve head. The scanning
laser polarymetry showed extensive losses in nerve fiber
layer of retina and the retinal thickness analysis
showed a reduction of the retina thickness in the
posterior pole. Study of the vision field evidenced the
relative and absolute scotomas.
Conclusions: The results show a necessity for
careful evaluation of the glaucoma examination results
in patients with drusen in the optic nerve head, because
of a high similarity of abnormalities produced by both
diseases. |
