AIM: To study the changes of automated static visual field in high myopia. METHODS: The static visual fields in 65 cases (130 eyes) with high myopia were tested by Dicon TKS-5000 Field Analyzer and their posterior polar lesions were observed. RESULTS: Among the 130 eyes, 115 eyes (88.5%) showed field abnormalities. Enlargement of the blind spot occurred in 86 eyes (66.2%), central relative scotomata in 75 eyes (57.7%), and diffuse field defects in 39 eyes (30.0%). Among the 75 eyes of central relative scotomata, only 51 eyes showed macular lesions under the ophthalmoscope (x2 = 22.042, P < 0.005). CONCLUSION: The visual field defects in the high myopic eyes relate to the degree of high myopia, the age of the patients and the severity of the posterior polar lesion. The appearance of visual field abnormalities in high myopic eyes detected by a quantified automated perimeter is prior to the appearance of the posterior polar lesions seen under the ophthalmoscope. The automated visual field examination is helpful for early diagnosis and treatment of high myopia. LA: Chinese
