背景。本前瞻性研究分析了hrt2视网膜模块作为黄斑裂孔诊断工具的有效性。术前状态对术后解剖和功能结果的影响也进行了讨论。术前和术后视网膜断层扫描图（HRT 2）与光学相干断层扫描（OCT III）和光谱光学相干断层扫描（SOCT）进行比较。对46例连续50眼的III/IV期黄斑裂孔患者行玻璃体切除术并内限制膜剥离和液体/空气交换。分析HRT 2， OCT III和8例SOCT图像。术前1周平均最佳矫正视力为0.086±0.074（0.01-0.35）。术后12个月最终最佳矫正视力为0.32±0.24（0.01-1.0）。第一次手术后1个月，46/50眼解剖成功，第二次干预后所有眼解剖成功。在33/50眼（66%）中，视力改善超过两条线。13眼术后视力保持稳定，4眼术后视力下降。hrt2的平均黄斑孔直径为497.2 μ m， OCT III的平均黄斑孔直径为490 μ m，椭圆形黄斑孔的数值不同。平均黄斑孔面积0.193 mm(2)。HRT 2的黄斑孔半径可与OCT III的最小直径进行比较。影响术后12个月的最终视力。hrt2黄斑模块可以诊断黄斑孔并评估其术后状态。这种技术有一些优点，因为它可以测量黄斑孔的半径、面积和深度。当HRT和OCT III测量的黄斑孔半径不同时，HRT似乎给出了更准确的数据，因为它显示了整个表面而不仅仅是视网膜的横截面。hrt2测量的黄斑孔半径和面积可影响术后功能结果。
Background. This prospective study analyzed the usefulness of the HRT 2 retina module as a diagnostic tool for macular hole diagnosis. The influence of the preoperative status on postoperative anatomic and functional results is also discussed. Preoperative and postoperative retinal tomography maps (HRT 2) were compared with optical coherent tomography (OCT III) and spectral optical coherent tomography (SOCT).Methods. Fifty eyes of 46 consecutive patients with stage III/IV macular hole underwent vitrectomy with internal limiting membrane peeling and fluid/air exchange. HRT 2, OCT III, and, in eight cases, SOCT images were analyzed.Results. The mean best corrected visual acuity 1 week before surgery was 0.086 +/- 0.074 (0.01-0.35). The final best corrected visual acuity 12 months after surgery was 0.32 +/- 0.24 (0.01-1.0). Anatomic success was noted in 46/50 eyes 1 month after the first surgery and in all eyes after the second intervention. In 33/50 eyes (66%), visual acuity improved over two lines. In 13 eyes visual acuity remained stable, and in four eyes worse visual acuity was noted postoperatively. The mean macular hole diameter in HRT 2 was 497.2 mu m and in OCT III was 490 mu m. Different values were observed in cases of oval macular holes. The mean macular hole area was 0.193 mm(2). The macular hole radius in HRT 2 can be compared with the minimal diameter in OCT III. It influences the final visual acuity 12 months after surgery.Conclusions. The HRT 2 macular module enables diagnosis of macular hole and evaluation of its postoperative status. This technique has some advantages because it enables measurement of the macular hole's radius, area, and depth. In cases when the macular hole's radius as measured in HRT and OCT III differs, HRT seems to give more exact data because it shows the entire surface rather than just a cross-section of the retina. Macular hole radius and area as measured with HRT 2 can influence postoperative functional results.
