Résumé
Retinal tears (RT) from posterior vitreous detachment (PVD) are an important and treatable cause of rhegmatogenous retinal detachment (RRD). Better understanding of the risk of RT from PVD will help plan urgent eye care. Prospective observational case series over two years. Patients presenting to their optometrist, family doctor or emergency department with flashes and floaters were directed to a research clinic. History and examination, including slit-lamp biomicroscopy (SLB) and indentation indirect ophthalmoscopy (IIO), were performed by a single investigator, with two month follow-up for patients with confirmed PVD. Main outcome measures were incidence of PVD, RT, and RRD. 1010 patients were recruited. 896 (89%) patients had PVD at first assessment, of which 89 (8.8% of total cohort, 9.9% of PVD eyes) had RT and 8 had RRD. 21 (3%) of the remaining PVD patients developed RT in the subsequent two months and a further 9 (11%) patients with RT at initial assessment developed further tears by two months. 7 (0.7%) had asymptomatic RT in the fellow eye. 15% of RT were only visible on IIO and not SLB. Weiss ring was absent in 32% of eyes with RT. Patients with RT or RRD were more likely than 'PVD-only' eyes to have blurred or missing vision (p < 0.001), have higher rate of blue-green cataracts (p < 0.001), and longer axial lengths (p < 0.05). This large, prospective study demonstrates a 9.9% rate of RT or RRD at the time of PVD, and emphasises the importance of IIO examination.

BACKGROUND
BACKGROUND
Retinal tears (RT) from posterior vitreous detachment (PVD) are an important and treatable cause of rhegmatogenous retinal detachment (RRD). Better understanding of the risk of RT from PVD will help plan urgent eye care.
METHODS
METHODS
Prospective observational case series over two years. Patients presenting to their optometrist, family doctor or emergency department with flashes and floaters were directed to a research clinic. History and examination, including slit-lamp biomicroscopy (SLB) and indentation indirect ophthalmoscopy (IIO), were performed by a single investigator, with two month follow-up for patients with confirmed PVD. Main outcome measures were incidence of PVD, RT, and RRD.
RESULTS
RESULTS
1010 patients were recruited. 896 (89%) patients had PVD at first assessment, of which 89 (8.8% of total cohort, 9.9% of PVD eyes) had RT and 8 had RRD. 21 (3%) of the remaining PVD patients developed RT in the subsequent two months and a further 9 (11%) patients with RT at initial assessment developed further tears by two months. 7 (0.7%) had asymptomatic RT in the fellow eye. 15% of RT were only visible on IIO and not SLB. Weiss ring was absent in 32% of eyes with RT. Patients with RT or RRD were more likely than 'PVD-only' eyes to have blurred or missing vision (p < 0.001), have higher rate of blue-green cataracts (p < 0.001), and longer axial lengths (p < 0.05).
CONCLUSIONS AND RELEVANCE
CONCLUSIONS
This large, prospective study demonstrates a 9.9% rate of RT or RRD at the time of PVD, and emphasises the importance of IIO examination.
