PURPOSE: To assess visual field abnormalities in suspected glaucoma patients showing evident asymmetry in cup-to-disc ratio. MATERIAL AND METHODS: Twenty-two hypertensive eyes in 11 subjects showing lateral differences in cup-to-disc ratio of more than 2/10 were included in the study. Conventional and short wavelength automated perimetry (SWAP) was performed with a Humphrey field analyzer. A retinal nerve fiber layer (RNFL) study was also performed. RESULTS: Differences in IOP were 1.23 mmHg (p < 0.05). No differences were seen in conventional automated perimetry between both eyes. Average sensitivity (SWAP) showed significantly lower (p < 0.05) in those eyes with greater cup-to-disc ratios. RNFL showed a higher rate of defects in eyes with a higher cup-to-disc ratio. CONCLUSIONS: Lateral differences in cup-to-disc ratio indicate structural glaucomatous damage which is related to IOP levels. Associated functional loss was seen with SWAP. LA: Spanish
