[Potential of ultrasound biomicroscopy of retinal periphery in cataract of different etiology].

Presence and pattern of peripheral retinal changes were studied using ultrasound biomicroscopy (UBM) in patients with cataract of different etiology. UBM was performed in 85 eyes of 65 patients. Mean age was 65, 75+8, 19 years old. UBM was performed using "Sonomed" equipment (USA). Morphology of revealed by means of UBM peripheral retinal changes was made in 5 eyes with uveal melanoma. The signs of retinoschisis were found in 82 eyes (96.5%) using UBM. The initial UBM signs represent inclusions in the inner retinal layers. With the progressing of schisis cystic splitting of retina was found. Confluence of distinct cysts into one schisis zone was characteristic for further progressing. Thus peripheral retinoschisis has acoustic stages, that are confirmed morphologicaly and can be revealed by means of UBM in the majority of old patients with cataract of different etiology.
