Advantages:

There is a strong need for an effective treatment for patients suffering from persisting floaters with an altered visual function and a reduced quality of life. Vitrectomy is a treatment allowing a nearly complete removal of floaters.

Methods:

Patients underwent a three-port pars plana vitrectomy performed under local anesthesia using a panoramic viewing system. Functional results were assessed with satisfaction and visual function questionnaires.

Effectiveness / Safety:

32 eyes (23 patients) were vitrectomized. For 31 eyes, patients were satisfied by the results with a complete resolution of symptoms in 29 eyes out of 32 (90.6%). For 2 eyes (6.25%) there was one small floater persisting after the surgery, those patients felt nevertheless satisfied by the reduction of their symptoms. These results were confirmed by a detailed visual function questionnaire. Retinal breaks and detachment are known complications of pars plana vitrectomy. In this group, 5 patients had a retinal detachment during the year following the surgery. 4 patients had a successful retinal surgery, with a final visual acuity of 0.1 to 0 LogMAR and felt satisfied by the result. One patient required repeated retinal surgeries and was left with a profound visual loss with a visual acuity under 1.3 LogMAR.

Take home message:

Vitrectomy is an effective treatment for disabling persisting floaters but the risk of retinal detachment must be taken into account.
