BACKGROUND
Premacular hemorrhage is among the causes of sudden deterioration of visual acuity. This study aimed to investigate the therapeutic outcomes of a new Q-switched Nd:YAG laser on premacular hemorrhage.
METHODS
Retrospective, case series study of 16 eyes from 16 patients diagnosed with premacular hemorrhage, including 3 cases of Valsalva retinopathy, 8 cases of retinal macroaneurysm, 3 cases of diabetic retinopathy, 1 case of trauma-related hemorrhage and 1 case with leukemia. A 1064nm Q-switched Nd:YAG laser was performed to puncture the posterior hyaloid and inner limiting membrane to drain the hemorrhage.
RESULTS
The success rate of 16 patients with premacular hemorrhage drainage was 100% in this study. Improved visual acuity was observed in each patient.
CONCLUSIONS
In this case series of 16 patients, the new Q-switched Nd:YAG laser was successful in draining premacular hemorrhage with no serious complications.
背景
黄斑前出血是导致视力突然下降的原因之一。本研究旨在探讨新型 Q 开关 Nd:YAG 激光治疗黄斑前出血的疗效。
方法
回顾性病例系列研究，纳入 16 例 16 只眼黄斑前出血患者，其中 3 例为 Valsalva 视网膜病变，8 例为视网膜大动脉瘤，3 例为糖尿病性视网膜病变，1 例为创伤性出血，1 例为白血病。采用 1064nm Q 开关 Nd:YAG 激光穿刺后脱离的玻璃体及内界膜以排出积血。
结果
本研究中 16 例黄斑前出血引流患者的成功率为 100%。每位患者的视力均有所提高。
结论
在本病例系列研究中，新型 Q 开关 Nd:YAG 激光成功排出黄斑前出血，且无严重并发症。
