特发性黄斑前膜的频域光相干断层扫描特征以及与视力的相互关系

Objective To observe the Fourier-domain optical coherence tomography(FD-OCT) characteristic of idiopathic epiretinal membrane (ERM) and its correlation with the patients visual acuity. Methods The 116 eyes (112 patients) with idiopathic epiretinal membrane were included in this study. All the patients had undergone examination of visual acuity (LogMAR chart), ocular fundus (direct ophthalmoscope and fundus pre-set lens), and FD-OCT (Zeiss HD-OCT) with the speed of 27 000 A scan/s, area of 6.0 mm× 6.0 mm, and mode of 512 × 128. The central fovea thickness (CFT), volume (V), average thickness (AT) were collected from the OCT readings, and the fovea thickness (FT) was measured manually. Data were analyzed using SPSS 16.0. Results The traction on retina caused by ERM can be divided into 3 types according to the OCT findings., no traction (9.48 %), tangential traction (84.48 %) and tangential traction with anterior-posterior traction (6.04 %). A total of 97 eyes (83.62 %) had retinal edema (diffuse or cystoid) and the edema located at the outer nuclear layer(ONL), outer plexiform layer(OPL)and inner nuclear layer (INL). A total of 14 eyes (12. 07%) had retinal nerve fiber layer (RNFL) schisis and 27 eyes (23.28%) had inner segment/outer segment j unction(Ls/OS) impairment. Statistic analysis revealed that BCVA was not related to the age, gender, types of traction, presence of IS/OS damage or RNFL schisis(P>0.05), but was related with CFT(P<0.05). Conclusions Idiopathic ERM can exert different types of traction on the macular, and cause different types of retinal lesions. OCT is a useful tool to measure these lesions. CFT reading is closely related to patients" visual acuity.
