[Short-wavelength automated perimetry and retinal nerve fiber layer evaluation in glaucoma suspects].
OBJECTIVE
To determine the correlation between the structural changes in the Retinal Nerve Fiber Layer (RNFL) and functional losses detected with ShortWavelength Automated Perimetry (SWAP) in a population of patients with suspected glaucoma.


METHODS
49 eyes of 49 ocular hypertensive subjects who met the selection criteria (intraocular pressure greater than 21 mm of Hg and normal standard visual fields) were studied. SWAP was performed with a modified Humphrey Field Analyzer. Visual field indexes (MD, CPSD) were calculated for SWAP. Semiquantitative RNFL scores were given separately to diffuse and localized defects of the RNFL.


RESULTS
The MD increased significantly (p<0.001) with higher Diffuse and Total RNFL scores, with good correlation coefficients. A small correlation was found between the CPSD and the RNFR scores (Diffuse, Total and Localized RNFL scores).


CONCLUSIONS
Diffuse retinal nerve fiber layer losses are associated with diffuse field loss (MD) while focal structural damage showed no correlation with visual field losses.
