To determine whether prone postoperative near visual acuity following macular hole surgery can be used as a reliable indicator of successful hole closure, data from 21 patients undergoing macular hole surgery were collected. Seventeen of the 18 patients with hole closure and all 3 patients with persistent macular holes had a Rosenbaum acuity better than preoperative visual acuity, yielding 94% sensitivity, 0% specificity, 85% positive predictive value, and 0% negative predictive value. Fourteen of the 18 patients with macular hole closure and all 3 patients with persistent macular holes had a Rosenbaum acuity better than 20/40, yielding 78% sensitivity, 0% specificity, 82% positive predictive value, and 0% negative predictive value. Although postoperative near visual acuity can predict macular hole closure with 94% sensitivity, the test is not clinically useful to predict hole closure because of the high surgical success rate of macular hole surgery. The test could be useful in encouraging patients to maintain head prone positioning and alleviate patient anxiety.
为了确定黄斑裂孔手术后俯卧位时的近视力是否可作为裂孔成功闭合的可靠指标，收集了21例行黄斑裂孔手术患者的数据。18例裂孔闭合患者中的17例以及所有3例持续性黄斑裂孔患者的罗森鲍姆视力均优于术前视力，敏感性为94%，特异性为0%，阳性预测值为85%，阴性预测值为0%。18例黄斑裂孔闭合患者中的14例以及所有3例持续性黄斑裂孔患者的罗森鲍姆视力优于20/40，敏感性为78%，特异性为0%，阳性预测值为82%，阴性预测值为0%。虽然术后近视力预测黄斑裂孔闭合的敏感性为94%，但由于黄斑裂孔手术的成功率较高，该检查对预测裂孔闭合在临床上并无用处。该检查可能有助于鼓励患者保持俯卧位并减轻患者焦虑。
