A. Assi et al., Estimation of the retinal nerve fibre layer thickness in the papillomacular area of long standing stage IV macular holes, BR J OPHTH, 83(5), 1999, pp. 573-576
Aim-To compare the thickness of the retinal nerve fibre layer (RNFL) in the
papillomacular area of patients with long standing stage IV macular holes
with age matched controls, using a scanning laser polarimeter.
Methods-The nerve fibre analyser (NFA) was used to measure the mean thickne
ss of the RNFL around the optic nerve head, the thickness values of tempora
l and nasal 45 degrees sectors and the integral values in 10 patients with
macular holes and in 10 age matched controls.
Results-The mean RNFL thickness around the optic nerve head was 79.71 (SD 1
5.06) mu n in the macular hole group and 75.1 (10.8) mu m in the control gr
oup (p = 0.44). The mean thickness in the temporal sector was 63.69 (12.08)
mu m in the macular hole group and 58.65 (8.9) mu m in the control group (
p = 0.3). The mean ratio between the temporal and nasal sector thickness va
lues was 0.8441 in the macular hole group and 0.7819 in the controls (p = 0
.42).
Conclusions-There was no significant difference in the thickness of the RNF
L in the papillomacular area in the two groups. This suggests that there ma
y be no changes in the thickness of the RNFL in patients with long standing
macular holes.
