OBJECTIVE: To evaluate the frequency of blue-on-yellow perimetry deficits in ocular hypertension patients and correlate these findings with central corneal thickness. METHODS: The blue-on-yellow perimetry and central corneal thickness were examined in 31 ocular hypertension patients with normal white-on-white perimetry and normal optic discs. The blue-on-yellow perimetry were tested by Octopus 101 automated perimetry using G2 strategy, and the central corneal thickness were detected with DGH-550 ultrasound pachymeter. One eyes of each patients was chosen for statistical analysis, and the differences of the intraocular pressure (IOP) and the central corneal thickness between the normal blue-on-yellow perimetry group and abnormal blue-on-yellow perimetry group were compared, and the correlation of IOP and central corneal thickness was analyzed. RESULTS: Twenty-one in 31 patients with ocular hypertension showed normal blue-on-yellow field, whereas that of the eyes (32.26%) was abnormal in the vision field test. The mean IOP in the abnormal blue-on-yellow perimetry group and normal blue-on-yellow perimetry group was (24.30 ± 1.89) mmHg and (25.48 ± 2.48) mmHg respectively without a significant difference between two groups (t = 1.32, P = 0.1963). The mean central corneal thickness in the abnormal blue-on-yellow field group and normal blue-on-yellow field group was (557.80 ± 16.41) μm and (576.00 ± 20.98) μm, respectively with a significant difference between two groups (t = 2.41, P = 0.0226). There was a significant correlation between IOP and central corneal thickness (P < 0.05). CONCLUSION: The mean central corneal thickness value in ocular hypertension patients with abnormal blue-on-yellow field is lower than that of normal blue-on-yellow field. It is valuable in the prediction of the development of glaucomatous damage among ocular hypertension patients if blue-on-yellow field result and central corneal thickness are taken into account together.
