特发性黄斑裂孔的黄斑裂孔直径、被破坏的光感受器细胞内外节直径及其与视力的相关性研究

Objective To observe the diameters of macular hole and destroyed boundary line between inner and outer segment (IS/OS) of the photoreceptors and the correlation with the visual acuity in patients with idiopathic macular hole(IMH). Methods The clinical data of 39 eyes (37 patients) with IMH were retrospective analyzed. All the patients had undergone the examinations of visual acuity (Snellen chart), intra-acular pressure, ocular fundus (indirect ophthalmoscope), and Fourier-domain optical coherence tomography (FD-OCT) whose speed was 27 000 A scan/s, area was 6.0 mm×6.0 mm, and the mode was 512×128. The diametres of macular hole and destroyed IS/OS, and the correlations with visual acuity were detected. Results The mean IogMAR was 0.99±0. 44 (ranged from 0. 15 to 2.00), the mean diameter of macular holes was (942.0± 348. 4)μm(ranged from 171 to 1491 μm), and the mean diameter of IS/OS disruption was (1870. 35±673.2) μm(range from 463 to 3176 μm). There was a significant correlation among the diameter of the macular hole, the diameter of the IS/OS disruption, and IogMAR in IMH (P= 0. 038, 0. 002, 0. 000). In eyes with closed macular hole after surgery, the IogMAR and the diameter of the IS/OS disruption had a significant decrease. Conclusion Using FD-OCT the photoreceptor changes can be visualized in vivo. The abnormality in the IS-OS boundary line appears to be involved for a much larger area beyond the macular hole itself, and persists there with small size even after the maeular hole closure surgery.
