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).
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.
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 microm and in OCT III was 490 microm. 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.
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.
本前瞻性研究分析了HRT 2视网膜模块作为黄斑裂孔诊断工具的实用性。还讨论了术前状态对术后解剖和功能结果的影响。将术前和术后的视网膜断层扫描图（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。
46例连续的III/IV期黄斑裂孔患者的50只眼接受了玻璃体切割联合内界膜剥除及液/气交换手术。分析了HRT 2、OCT III图像，其中8例还分析了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）。首次手术后1个月，46/50只眼解剖复位成功，第二次干预后所有眼均成功。50只眼中33只眼（66%）视力提高超过两行。13只眼视力保持稳定，4只眼术后视力下降。HRT 2测量的黄斑裂孔平均直径为497.2微米，OCT III测量的为490微米。椭圆形黄斑裂孔病例观察到不同的值。黄斑裂孔平均面积为0.193平方毫米。HRT 2测量的黄斑裂孔半径可与OCT III测量的最小直径相比较。它影响术后12个月的最终视力。
HRT 2黄斑模块能够诊断黄斑裂孔并评估其术后状态。该技术具有一些优势，因为它能够测量黄斑裂孔的半径、面积和深度。当HRT和OCT III测量的黄斑裂孔半径不同时，HRT似乎能提供更准确的数据，因为它显示的是整个视网膜表面，而不仅仅是视网膜的横截面。用HRT 2测量的黄斑裂孔半径和面积会影响术后功能结果。
