Background It is very important for us to understand retinal function change in the patient with diabetic mellitus in clinic. At present,the study about diabetic mellitus associated with macular edema includes fundus fluorescense angiography ( FFA) and multifocal electroretinogram ( mfERG) etc.. However, seldom research is performed in the mfERG findings for different types of diabetic macular edema. Objective This study aimed to investigate the mfERG change in different types of diabetic macular edema compared with normal population. Methods Fifty-seven eyes with diabetic macular edema from 40 patients and 35 eyes from age-and gender-matched normal subjects were enrolled in this study. The eyes with diabetic macular edema were assigned to local macular edema group (n=16) ,diffuse macular edema group (n = 22) and cystoid macular edema ( n = 17 ) based on the manifestation of FFA. MfERG was recorded in all the individuals. The informed consent was obtained from each subject prior to any the medical examination. Results In focal diabetic macular edema group,the response density of P1 wave was significantly attenuated in ring 1 , showing a statistical difference in comparison with controls (t =2. 170,P = 0.038) ,and the latencies of P1 and N1 waves showed obvious prolong in ring 4 and 5 (t = 2.519,P = 0. 017 ;t = 2. 451 ,P = 0. 020). In diffuse diabetic macular edema group,the response densities of P1 and N1 waves were declined in ring 1,3,5 and ring 1,3,4,5 respectively,and the latencies of P, in ring 3,4 were significantly delayed respectively in comparison with controls (all P < 0. 05 ). In cystoid diabetic macular edema group, the response densities of P1 and N1 waves were lowed from ring 1 through 5 respectively, and the latencies of P1 and N1 waves were significantly longer from ring 3 through 5 and ring 4 respectively with the statistically significant difference from controls (all P<0. 05). The visual function of fovea was badly damaged. Conclusion These studies indicate that the most serious damage of visual function is in foveal area in cystoid diabetic macular edema group, and is then parafoveal area of diffuse diabetic macular edema group and perifoveal area in focal diabetic macular edema group. The outcome of mfERG presents a good consistency with FFA findings in the patients with diabetic macular edema.

BACKGROUND: The morbidity of diabetes mellitus increased recently.There are few reports about the pulmonary function status of the patients with diabetes mellitus.OBJECTIVE: To comparably observe the difference of the pulmonary function status between patients with diabetes mellitus and normal persons,and to probe into the relationship between the course of disease of diabetes mellitus and the functional change of pulmonary function.DESIGN: Case controlled observation SETTING: Renmin Hospital, Wuhan University PARTICIPANTS: Totally 90 patients with diabetes mellitus hospitalized in the Renmin Hospital, Wuhan University between January 2000 and De cember 2003 were recruited. All the patients participated in the experiment voluntarily. Totally 20 cases were of insulin dependent diabetes mellitns (IDDM) and 70 cases were of non-insulin dependent diabetes mellitus (NIDDM). Another 90 cases were divided into 2 groups with the boundary line of 10 years: group with disease course <10 years (n=40) and group with disease course >10 years (n=50). And 30 normal persons with healthy pulmonary function was set as healthy control group, all the testees were voluntary participants in the experiment.METHODS: Pulmonary function index of the participants of each group was measured: vital capacity (VC), forced vital capacity (FVC), forced expiratory volume in 1 s (FEV1%), peak expiratory flow rate(PEFR)maximal voluntary ventilation (MVV) and comparison was performed between them.Comparison of the pulmonary function status of the patients between different levels of diabetes mellitus.pulmonary function between different groups : Compared with health control group, VC , FVC and MVV of the patients with diabetes mellitus was significantly decreased (t=1.999-2.301, P < 0.05).There was no significant difference in the VC, FVC and MVV between patients with monary function between patients with different diabetes mellitus: the pulmonary function status in the group with disease course >10 years was improved less than that in the group with disease course <10 years [ VC (L):2.62±0.65 vs 3.25±1.25;FVC(L): 2.40±0.52 vs 3.21±0.98;FEV1%:75.31±2.31 vs 80.63±5.56;PEFR (L/s):4.33±0.68 vs 5.98±1.02;MVV (L/s): 76.22±6.98 vs 89.21±5.69 (t=2.012-2.350, P < 0.05)].CONCLUSION: Pulmonary function of the patients with diabetes mellitus has reduced tendency compared with the normal persons, and the pulmonary function of the patients with long course of disease decreases significantly. More attention should be paid to diabetes patients' pulmonary function changes.
