Objective To study the major factors which affect quality of life of Chinese patients with diabetic retinopathy,and provide basis raising the patients condition of health and quality of life. Methods Quality of life of 179 patients with different stages of diabetic retinopathy and 30 healthy persons was measuerd by the medical outcomes study 36-item short form health survey(SF-36)and the brief scale of quality of life of WHO(WHOQOL-BREF),then the affectting factors were analysed by step regression. Results The major factors which affect quality of life of patients with diabetic retinopathy included:bilateral visual acuity(BVA),different category of retinopathy,course of disease,economic condition,personality,medical care and age. Conclusion The study suggests that bringing about the transformation from the biologic medical model to bio-psycho-social medical model is important to improve quality of life of the patients with diabetic retionpathy.

Objective To study the visual field defects and its correlation factors in nonarteritic anterior ischemic optic neuropathy (NAION). Methods One hundred and thirty-nine patients of NAION with complete visual field examination results were included in this study. There were 65 males （46.7%）and 74 females （53.3%），with an average age of （56.2plusmn;10.8） years. All the patients had undergone the examinations of visual acuity，refraction，refractive media, slit lamp ophthalmoscope, color fundus photography, visual field, blood pressure, blood routine test and blood biochemistry test. Fundus fluorescein angiography (FFA) was carried out in 125 patients. The visual field characteristics and its correlation factors were statistically analyzed, and the FFA and visual field results of 77 eyes were comparatively analyzed. Results The visual field examination showed typical inferior defect in 48 eyes (34.5%), arcuate scotoma in 24 eyes (17.3%), atypical arcuate scotoma in 24 eyes (17.3%), defuse defect in 20 eyes (14.4%), superior defect in 10 eyes (7.2%), superior defect with inferior arcuate scotoma in five eyes (3.6%), inferior defect with superior arcuate scotoma in eight eyes (5.8%). The mean defect （MD）value ranged from -3.0 to -32.0，with an average of -17.9plusmn;7.9. Among 77 eyes with FFA data, the FFA and visual field defect area were highly consistent seven eyes (9.1%), consistent in 26 eyes (33.8%), some kind of consistent in 39 eyes (50.6%), completely inconsistent in five eyes (6.5%). Multiple lineal regression analysis showed that mean red cell volume (MCV) (beta;=0.203，t=2.005) and cholesterol level (CHOL) (beta;=0230，t=2.244) were correlation factors of MD (P＜0.05). Conclusion The visual field defect of NAION shows a variety of patterns which may be mainly influenced by MCV and CHOL.
