Methods: Retrospective analysis of medical records on patients diagnosed with PVD, retinal tears, or vitreous hemorrhage at the Department of Ophthalmology at Sahlgrenska University Hospital, a tertiary eye center. Results: Between February and July 2009, 365 patients consulted the Department of Ophthalmology for PVD-related symptoms. The incidence of retinal tears was 14.5% (n=53) and that of vitreous and/or retinal hemorrhage was 22.7% (n=83). For analysis of possible predictors for complications to PVD, patients diagnosed with retinal tears or vitreous hemorrhage between May and July 2009 were also included in the study, resulting in a total of 426 patients. Predictors of a retinal tear were symptoms of visual impairment (P=0.024), the presence of vitreous or retinal hemorrhage at examination (P<0.001), and a duration of symptoms for <24 hours (P=0.004). Symptoms of flashes did not constitute an extra risk of retinal tears (P=0.135). Subsequent retinal pathology (follow-up time 4.5 years), including vitreous detachment/hemorrhage or retinal tears/detachment, occurred more often in patients presenting with a retinal tear. For patients with a retinal tear, the relative risk of having a retinal detachment in the same eye during the follow-up time was 17.7 when compared to patients without a retinal tear (risk ratio 17.7, 95% confidence interval 2.2–145). Conclusion: Patients seeking care on the first day have a higher risk of retinal tears. Also, symptoms of visual loss or a history of previous PVD-related pathology and vitreous/retinal hemorrhage at examination indicate a substantially higher risk of retinal complications. These findings may lead to better management and order of priority among these patients.
