Risk factors and central threshold visual field damage in 500 cases with glaucoma
Lin X; Li R-ZInternational Journal of Ophthalmology 2005; 5: 112-114
AIM: To explore the relationship between the risk factors of glaucoma and the changes of the central threshold visual field. METHODS: A total of 500 cases (980 eyes) with questionable glaucoma were divided into 4 groups based on their risk factors, and their central 30° threshold visual fields were examined through the SDT340 program Top-conSBP2020 auto perimeter from Japan. RESULTS: The central visual-field damaging rates of the Mixed Group, the Abnormal Cup-tray Group, High Eye Pressure Group and Symptom Group were 70%, 48.3%, 47.5% and 35.8% respectively. The Mixed Group is remarkably different from the other three groups (P < 0.01). The difference in the visual field damage of threshold between the myopic patients with incorrect phototropism and the presbyopic ones with incorrect phototropism is remarkable (P < 0.01). There was no difference on the damage of the central threshold visual field among different ages (P > 0.05). CONCLUSION: Central threshold visual field damage of myopic patients with incorrect phototropism is more serious than the presbyopic ones with incorrect phototropism. It is a risk factor causing visual field damage that the intraocular pressure grows higher with the change of optic papilla. LA: Chinese
