Safety and Efficacy of YAG Laser Vitreolysis for the Treatment of Vitreous Floaters: An Overview
摘要： Emerging evidence has suggested that the entoptic phenomena associated with vitreous opacities (i.e. vitreous floaters) are more bothersome than previously believed. In addition, the prevalence of vitreous floaters is likely increasing due to the evolving global pandemic of myopia. The use of YAG laser vitreolysis for the treatment of annoying vitreous floaters has attracted significant attention in recent years as the technique offers a number of potential advantages. Unfortunately, the currently available evidence that is needed to guide clinical practice is both very limited and contradictory. As a consequence, the technique remains highly controversial. A review of the existing literature sheds light on patient- and treatment-related factors that may significantly affect both the effectiveness and the safety of the procedure. The current article discusses important aspects of key publications on the topic, offers suggestions for clinical practice, and highlights unmet needs that should be addressed by future research.

Laser Vitreolysis for Symptomatic Floaters is Not Yet Ready for Widespread Adoption
摘要： Vitreous floaters are common, related to age, myopia, genetic predisposition, and infiltration of the vitreous body. A subset of patients report symptoms impacting their quality of vision. Treatment with laser vitreolysis, the use of an Nd:YAG laser to vaporize the collagenous vitreous opacities, appears to be used more frequently; however, data regarding long-term safety and effectiveness are lacking. We present currently available data regarding efficacy and safety, as well as additional considerations. Laser vitreolysis of symptomatic floaters should not be routinely performed without additional studies documenting its safety and long-term efficacy. Ideally, the procedure would be effective in the majority of patients and be FDA-approved based on the results of an FDA registration trial before widespread adoption.

Objective assessment of YAG laser vitreolysis in patients with symptomatic vitreous floaters
摘要： Background: To objectively evaluate YAG laser vitreolysis for symptomatic vitreous floaters using color photo imaging. Methods: In this interventional and prospective study, 32 eyes of 32 patients with symptomatic vitreous floaters secondary to posterior vitreous detachment (PVD) were treated with a single session of yttrium aluminum garnet (YAG) laser. Primary outcomes were objective and subjective changes measured by masked grading of color fundus photographs and National Eye Institute Visual Functioning Questionnaire 25 (NEI VFQ-25), respectively. Secondary outcomes included Early Treatment Diabetic Retinopathy Study (ETDRS), best-corrected visual acuity (BCVA) and adverse events. Wilcoxon signed-rank test was used to analyze the results of the objective and subjective assessments at each time point. P < 0.05 was considered statistically significant. Results: Thirty-two patients (32 eyes; 13 men and 19 women) with symptomatic vitreous floaters were enrolled in this study (mean age: 59.4 years). All study patients were followed up for 6 months. Following the laser vitreolysis, there was a statistically significant improvement in both the near visual function (z = ? 2.97; p = 0.003; r = 0.633) and visual disturbance rate (z = ? 3.97; p < 0.001; r = 0.84). Distance visual function did not show statistically significant difference after the laser procedure (p = 1.00). Color fundus photograph did reveal vitreous opacity improvement over time in 93.7% of study eyes (partial improvement in 37.5% and total improvement in 56.2% of study eyes). During the follow-up period, recurrence of vitreous floaters, BCVA deterioration and adverse events were not observed. Conclusions: YAG laser vitreolysis decreased the amount of vitreous floaters opacities seen on color fundus imaging and improved related symptoms according to the NEI VFQ-25 responses.
