AIM: To evaluate the ciliary body and peripheral retina in degenerative retinoschisis associated with pars plana cysts using ultrasound biomicroscopy (UBM).
METHODS: 18 eyes of 12 patients with degenerative retinoschisis associated with pars plana cysts were selected through binocular indirect ophthalmoscopy and Goldmann three mirror lens examination, both with scleral depression. These patients were studied in detail with UBM.
RESULTS: Study of the ciliary body with UBM showed pars plana cysts of different size and uneven shape. In cross sections the morphology of pars plana cysts in detail and the close relation of the cysts with the oral region and the peripheral retina, where areas of cystoid degeneration and retinoschisis were present, were observed. In transverse sections three main morphological aspects of pars plana cysts could be differentiated ("isolated," "confluent," and "clustered" cysts). Furthermore, ultrabiomicroscopy allowed differential diagnosis between retinoschisis and associated retinal detachment in six eyes.
CONCLUSIONS: The study of peripheral degenerative retinoschisis and pars plana cysts is possible in vivo by means of UBM, showing the detailed morphology of the lesions (not otherwise evident through ophthalmoscopic examination) and the close relation between pars plana cysts, cystoid degeneration, and peripheral retinoschisis.
