목적 : To examine the prevalence of visual field deterioration in fellow eyes of patients with worsening open-angle glaucoma and to evaluate the spatial concordance of visual field deterioration between fellow eyes.
방법 : One hundred-sixteen open-angle glaucoma patients who underwent 8 or more visual field examinations over ≥ 6 years of follow-up were included. Rates of the fast and slow components of visual field decay for each of 52 visual field test locations were calculated with pointwise exponential regression (PER) analysis. Spatial concordance of visual field deterioration in fellow eyes was evaluated with a concordance ratio and by comparing the rate of decay in corresponding modified Glaucoma Hemifield Test (GHT) clusters.
결과 : The average visual field mean deviation was −8.5dB and mean follow-up time was 9.0years. Sixty-three patients had mild damage, 23 had moderate damage, and 30 had severe damage. The mean concordance ratio was 0.46 for the mild group, 0.33 for the moderate group, and 0.35 for the severe group. Thirty-one patients (27%) had deterioration in concordant locations (P <0.05). Visual field deterioration was greater in the superior hemifield than the inferior hemifield (P <0.05) when evaluated with both the concordance ratio and modified GHT cluster analysis methods.
결론 : : Visual field deterioration is frequently bilateral in patients with open-angle glaucoma. Visual field deterioration occurred more frequently in the superior hemifield. There is only fair spatial concordance with regard to visual field deterioration between the fellow eyes of an individual. We conclude that testing algorithms taking advantage of inter-eye spatial concordance would not be particularly advantageous in the early detection of glaucomatous deterioration.
