Purpose:
To evaluate Weiss ring and floaters as indexes of posterior vitreous detachment.
Methods:
Using biomicroscopy and indirect ophthalmoscopy, we examined the posterior vitreous in 200 consecutive eyes with posterior vitreous detachment.
Results:
In 200 eyes with posterior vitreous detachment, biomicroscopy disclosed complete, incomplete, and no Weiss ring in 102 (51%), 72 (36%), and 26 (13%) eyes, respectively. Indirect ophthalmoscopy showed the glial ring in 58 (56.9%) and 16 (22.2%) of the eyes, with a complete (102 eyes) and incomplete (72 eyes) Weiss ring, respectively. Although the incidence of floaters was significantly correlated with the presence of the glial ring (P = .0014), 60 (58.8%) and 49 (68.1%) of the eyes with a complete (102 eyes) and incomplete (72 eyes) glial ring, respectively, had no floaters.
Conclusion:
Detecting the detached posterior vitreous cortex by biomicroscopy is essential regardless of the presence of Weiss ring or floaters.
