| Summary: |
Purpose: To compare
the morphological parameters of the optic disc in
patients with low myopia and primary open angle glaucoma
(POAG) and in patients with glaucoma without refractive
errors.
Material and methods: 53 patients, aged 33-88
(56.2±11.9) with POAG were qualified for our study. The
group was divided into two: first group consisted of 14
patients – 11 women and 3 men, aged 41 – 83 (58.2±10.9)
comprising 28 eye balls with low myopia (-0.5 Dsph to
-3.5 Dsph) and POAG. The second group consisted of 38
patients: 24 women and 14 men, aged 33 – 80 (51.0±13.4)
comprising 71 eye balls including 43 emetropic eyes, 26
eyes with hyperopia (+0.5Dsph to +3.0 Dsph) and 2 eyes
with astigmatism. All patients demonstrated early
changes in visual field 1-2 stage due to the Aulhorn
classification. The measurements of the morphological
parameters of the optic disc were made with confocal
scanning laser ophthalmoscopy using Heidelberg Retina
Tomograph – HRT II with glaucoma software. We analyzed
the following parameters: optic disc area, cup area, rim
area, cup/disc ratio, linear c/d ratio, mean cup depth,
maximum cup depth. The statistical analysis was made
using Kołomogarow – Smirnow test.
Results: All analyzed parameters were higher in
patients with low myopia and POAG than in patients with
only POAG. The results in both groups were different but
still no statistically significant.
Conclusions: Low myopia has an influence on the
optic disc morphology in patients with POAG. |
