Purpose:
To explore the characteristics of vitreoretinal lymphoma (VRL) in B-scan ultrasonography.
Design:
Single-center case-control study.
Participants:
A total of 106 eyes of 56 patients with biopsy-proven VRL and 86 eyes of 59 patients with uveitis were included.
Methods:
B-scan ultrasonography of the included eyes was performed. Evaluated were the ultrasonographic signs as well as a special pattern termed centrifugal condensation, which refers to the peripherally hyperreflective appearance of the vitreous haze in ultrasonography.
Main Outcome Measures:
Posterior vitreous detachment, vitreoretinal adhesion, location of vitreous haze, thickening or occupying lesions of the retina, retinal detachment, and centrifugal condensation pattern of vitreous haze were evaluated through B-scan ultrasonography. The incidences of these signs were compared between the 2 groups; odds ratios (ORs) were calculated.
Results:
The incidence of vitreoretinal adhesion in patients with VRL (6/106) was lower than in patients with uveitis (20/86; P = 0.001; OR: 0.195; 95% confidence interval [CI]: 0.073-0.522). The incidence of retinal thickening or occupying lesions in patients with VRL (21/106) was higher than that in patients with uveitis (1/86; P = 0.005; OR: 19.068; 95% CI: 2.455-148.265). The incidences of posterior vitreous detachment and retinal detachment were not significantly different between the 2 groups (P = 0.453 and P = 0.310, respectively). The centrifugal condensation pattern was more likely to be observed in patients with VRL (49/106) than in patients with uveitis (13/86; P < 0.001; OR: 4.831; 95% CI: 2.416-9.660).
Conclusions:
B-scan ultrasonography might help to provide clues for the suspicion of VRL. Thickening or occupying lesions of the retina and centrifugal condensation pattern of vitreous haze might be suggestive of VRL.
