Abstract
AIM: To study the efficacy and safety of Ultra Q- YAG vitreolysis for vitreous floaters. <br> METHODS: Retrospective case series study. From September 2014 to May 2015 in Beijing Aier - Intech Eye Hospital, 263 cases (340 eyes) with vitreous floaters were involved. All patients underwent visual acuity, intraocular pressure, slit lamp, mydriatic fundus, B ultrasonic examination, and recorded the form of a vitreous opacity excluded pathological fundus lesions. All the patients were divided into two groups: Group A (<30 years old) 78 cases (82 eyes); the morphology of vitreous opacity were dot, filiform and mesh. Group B ( > 45 years old), 185 cases (258 eyes), the morphology of vitreous opacity was Weiss ring, translucent flocculent clouds or dense fibrous membrane. Patients in 30 - 45 years old were eliminated because of the untypical opacity factor. The treatment was done by the same physician.

According to the scores of the questionnaires, patients were divided into 3 groups: no improvement ( 1 - 2 points), partial improvement (3-5 points), significant improvement (6-10 points ). At 1mo after treatment, Group A: no improvement in 9 eyes (11. 0%), partial improvement in 57 eyes (69. 5%) and significant improvement in 16 eyes (19. 5%); Group B: no improvement in 0 eyes, partial improvement in 23 eyes ( 8. 9%) and significant improvement in 235 eyes (91. 1%); all the patients had no complications. <br> CONCLUSION: The treatment with YAG vitreolysis for vitreous floaters is safe and effective, especially for the patients more than 45 years old whose vitreous floaters caused by posterior vitreous detachment.关键词
