| Summary: |
Purpose: To
evaluate the efficacy of Heidelberg retinal flowmeter (HRF)
for retinal microcirculation in glaucoma.
Material and methods: Forty-six patients with
glaucoma (22 with POAG and 24 with NTG) and 16 healthy
volunteers were examined in the years 2000 – 2002.
Diagnosis of glaucoma was based on typical criteria. The
inclusion criteria were following: only medical therapy,
no other ocular changes, refraction errors no higher
than 4,0 D, no systemic diseases, except hypertension in
normalized phase. In every case the HRF examination was
done by the author of the paper under the same
conditions. The measurement was performed in the nasal
and temporal peripapillary areas. The results were
calculated using AFFPIA program.
Results: No significant differences were found
between the glaucomatous patients and healthy persons as
well as between the POAG and NTG. Statistical analysis
based on median values of the flow revealed significant
differences in the flow depending on the changes of
optic disc and beta-blockers therapy.
Conclusions: The examination of retinal
microcirculation with HRF technique is not useful in
everyday clinical evaluation of glaucomatous damage.
However this technique may be suitable in the assessment
of the retinal flow changes caused by medical therapy,
also in glaucoma. |
