ABSTRACT
PURPOSE: To evaluate the role of 25 gauge pars-plana vitrectomy (25G-PPV), after a careful patient selection, when we find highly annoying vitreous floaters and to question if this is an ethical therapeutic option. METHODS: A retrospective study of eight eyes (seven patients) aged 58+/-14 years old (range 42-78) high myopes and pseudophakes who underwent 25G-PPV. Clinical data and visual acuity were studied at six to twelve months follow-up. Health-related functioning and quality of life was measured with the 39-item National Eye Institute Visual Functioning Questionnaire (NEI VFQ-39). RESULTS: No complications were observed. All patients were satisfied. Safety at third month was 100% and 37.5% improved one or more lines of visual acuity. CONCLUSIONS: Vitreous floaters can be often undervaluated by ophthalmologists, resulting in no intervention. Conventional 20 gauge PPV after a carefully examination can be an effective option for some authors. 25G-PPV incorporates also advantages as the early recovery, with little complications in pseudophakic eyes.

The method of the angiogenic response of the chick embryo chorioallantoic membrane is applied to study the tumor angiogenic factor, that was present in the aqueous humor but not in the vitreous humor of patients with choroidal melanoma or retinoblastoma.
