Vitreous floaters are visual phenomena caused by degenerative changes of the vitreous gel.
Although symptomatic vitreous floaters might be associated with retinal breaks or serious retinal detachment, especially when floaters increase suddenly and possibly accompanied by light flashes [4], it is usually thought to be harmless and natural aging process, and clinicians usually pay little attention to patients' discomfort.
The study group consisted of patients with symptomatic vitreous floaters who primarily visited Kangdong Sacred Heart Hospital Retina Clinic to evaluate their floater symptoms and who agreed to participate in the study.
The Vitreous Floaters Symptom Questionnaire and psychological evaluation were done before ophthalmologic examinations.
We compared OCT-based PVD status, psychological parameters, and other clinical factors between patients with symptomatic vitreous floaters and controls.
Endophthalmitis after vitrectomy for vitreous floaters is reported sporadically.
In summary, the 27-gauge vitrectomy was effective and safe for symptomatic vitreous floaters. However, it should be noted that since more healthy young people with excellent vision are trying, even eager to resolve their floaters through seemingly straightforward PPV, potential complications such as cataract, retinal detachment, and even devastating endophthalmitis should be explicitly addressed before this treatment.
