研究目的
To elucidate the relationship between systemic risk factors and different patterns of diabetic macular edema (DME) determined with optical coherence tomography (OCT).
研究成果
Micro- or macro-albuminuria might be more frequent and HbA1c might be higher in patients with DRT. These patients were also determined to be younger than patients with non-DRT.
研究不足
The sample size was small and represents the results of a single center. A longitudinal study with a control group may provide more informative results. Other OCT aspects such as external limiting membrane and the junction between the inner and outer segments of photoreceptors were not investigated.
1：Experimental Design and Method Selection:
A cross-sectional study design was used to classify DME by OCT into DRT, CME, and SRD patterns and evaluate their relationship with systemic risk factors.
2：Sample Selection and Data Sources:
57 patients with DME were included, with data on systemic factors and OCT patterns collected.
3：List of Experimental Equipment and Materials:
Spectral-domain OCT (Heidelberg Retinal Angiography-Optical Coherence Tomography-II, Germany) was used for imaging.
4：Experimental Procedures and Operational Workflow:
Patients underwent ophthalmic examination and OCT imaging. DME patterns were classified based on OCT images by retinal specialists.
5：Data Analysis Methods:
Statistical analysis was performed using SPSS 18.0 for Windows, with Pearson χ2 test and Kruskal-Wallis test used for comparisons.
