BACKGROUND
The purpose of the present study was to quantitatively assess the mean macular thickness in diabetic patients using optical coherence tomography and its correlation with visual acuity.
METHODS
A prospective case series study was undertaken of consecutive diabetic patients referred to a tertiary eye care centre for an eye check up from January 2003 to June 2003. One hundred and five eyes from 55 patients with varying degree of diabetes underwent optical coherence tomography examination. The study patients were divided into four groups: group I, non-proliferative diabetic retinopathy (NPDR); group II, NPDR with clinically significant macular oedema (CSME); group III, proliferative diabetic retinopathy (PDR); and group IV, PDR with CSME.
RESULTS
The mean macular thickness of the entire group was 256.0 +/- 129.7 microm. A positive correlation (r = 0.424, P < 0.0001) was evident between mean macular thickness and visual acuity.
CONCLUSION
Optical coherence tomography is a useful tool for objectively monitoring macular thickness in patients with diabetic retinopathy. Mean macular thickness correlates with visual acuity.
背景
本研究的目的是使用光学相干断层扫描定量评估糖尿病患者的黄斑平均厚度及其与视力的相关性。
方法
对2003年1月至2003年6月转诊至三级眼科护理中心进行眼部检查的连续糖尿病患者进行前瞻性病例系列研究。对55例不同程度糖尿病患者的105只眼睛进行了光学相干断层扫描检查。研究患者分为四组：第一组，非增殖性糖尿病视网膜病变（NPDR）；第二组，伴有临床显著性黄斑水肿（CSME）的NPDR；第三组，增殖性糖尿病视网膜病变（PDR）；第四组，伴有CSME的PDR。
结果
整个组的黄斑平均厚度为256.0±129.7微米。黄斑平均厚度与视力之间存在显著正相关（r = 0.424，P < 0.0001）。
结论
光学相干断层扫描是客观监测糖尿病视网膜病变患者黄斑厚度的有用工具。黄斑平均厚度与视力相关。
