Аннотация
Residual vitreous base after vitreoretinal surgery was evaluated by ultrasound biomicroscopy (UBM). Twenty aphakic and pseudoaphakic patients (20 eyes) undergoing surgery for different vitreoretinal diseases were evaluated by high-frequency (50 MHz), high-resolution (50 microm) UBM, performed the day before surgery, weekly up to 1 month after surgery and then monthly. One week after surgery, the vitreous remnants were 'hardly visible' in 3 cases, 'visible' in 6 cases and 'highly visible' in 11. At the end of the follow-up (2.2 months), the 'hardly visible' cases increased to 6 and the 'visible' cases to 12, while the 'highly visible' cases decreased to 2. UBM demonstrated that vitreous base remnants were present in spite of accurate surgery; a spontaneous volume reduction of vitreous was observed during the follow-up.
