Anomalies of anterior segments are often complicated in congenital cataract. Such anomalies cause complications during surgery. In order to avoid complications, preoperative evaluation for anterior segments is important. Here we demonstrate usefulness of ultrasound biomicroscopy (UBM) for safety congenital cataract operation.
We show two cases of congenital cataract. UBM type-840 (Humphrey Instruments, San Leandro, CA, USA.) and UD-1000 (TOMEY, Nagoya, Japan) were used for evaluation before operation.
Case 1) A 3-month-old infant with bilateral membranous cataracts was examined. As though his lens was thin, the UBM findings for the other parts of the anterior segments were normal including pars plana or ciliary body (Figure left, arrow). So we decided to operate using a pars plana lensectomy (PPL) without any complications.Case 2) A 1-month-old infant with bilateral cataracts was examined. The UBM revealed immature appearance of pars plana or ciliary body and extended zonules of Zinn (Figure right, arrow). We prospected that PPL is risky owing to such anomalies, and we operate his eye using a phacoemulsification and aspiration (PEA).There was no complication during and after surgery. Thus, we can avoid complications during and after operation owing to UBM information.
Selection of operation method is important for congenital cataract and UBM is useful by providing important information and evaluation of its characteristics.
