Objective
To investigate the relationship of clinical indexes between retinopathy in systemic-lupus-erythematosus （SLE）nephritis and SLE，and to discuss its clinical significance.
Method
The clinical data of 43 cases of SLE nephritis with ocular fundus diseases were retrospectively analyzed.The relationships between retinopathy and kidney defect，general lesions，SLEDAI grade，antinuclear antibody （ANA），anti-double stranded DNA，complement 3 and antiphospholipid antibodies were analyzed with Logistic regression respectively.
Results
In 86 eyes of the43paitents，there were retinal cotton wool spots in51eyes（59.3%），edema of optic disk in 43 eyes（50.5%），retinal haemorrhage in 12 eyes（14.0%），retinal artery occlusion in 5 eyes（5.8%），central retinal vein occlusion in 2 eyes（2.3%），retinal detachment in 3 eyes（3.5%），optic atrophy in 2 eyes（2.3%），and neovascularization in 2 eyes（2.3%）.Logistic regression analysis revealed that SLEDAI grade had linear dependent relation with cotton wool spots and optic disk edema（chi;2=42.154，6.498;P＜0.001），and didnrsquo;t have any correlation with proteinuria，hematuria and kidney function.Linear relation between retinal vascular occlusion and antiphospholipid antibodies was found（chi;2=24.475，P＜0.001）.Retinal haemorrhages，retinal detachment，optic atrophy and neovascularization did not correlate with clinical features.
Conclusion
SLEDAI grade had linear dependent relation with cotton wool spots and optic disk edema in patients with SLE nephritis，and Linear relation between retinal vascular occlusion and antiphospholipid antibodies is ascertained. Ocular fundus diseases are clinically important for evaluating the therapeutic responses and prognosis in lupus nephritis.
