METHODS: Totally 164 eyes of 127 patients with macular edema were involved in this study. According to different diseases, they were divided into 3 groups: age-related macular degeneration(AMD)(38 eyes), retinal vein occlusion(RVO)(43 eyes)and diabetic macular edema(83 eyes)groops. All patients underwent the examinations of optometry, optical coherence tomography scanner(OCT)and microperimeter. Correlation analysis was performed using Pearson, and t-test among groups.

RESULTS: Mean sensitivity(MS)values and fixation rate(P1, P2)of total patients with macular edema were significantly correlated with their BCVA, meanwhile the CRT was negatively correlated. MS values were significantly correlated with BCVA in AMD group, but the P1, P2 and CRT were not correlated. In DME and CRVO groups, MS values and P1, P2 were significantly correlated with BCVA, and CRTs were negatively correlated in DME but not correlated in CRVO. In BRVO group, MS values and CRTs were all not correlated with BCVA.

CONCLUSION:Microperimetry is probably a better subjective assessment for AMD macular function than OCT, and could be combined with OCT for function follow-up in DME and CRVO patients. For BRVO microperimetry might indicate certain macular dysfunction that could not be detected by VA or CCT. Microperimetry could be a subjective examination for the assessment of macular edema combined with OCT.
