Clinical characteristics of cataract morphology observed by UBM and operating microscopic examination by patient case.

UBMUBM typeOperating microscopyCongenital membranous cataract subtype

(1) OS: thickened pizza-shaped1Lens appeared white opaque with a red mass in the center. There were lots of vessels in the lensVascular membranous cataract (OM-type 4)
(2) OD: flying saucer-shaped3Pupil covered by a circular white opacity (right eye) and irregular white opacity (left eye) in the center before cataract surgery. A semiclear area in the peripheryLens cortex was mostly absorbed (OM-type 2)
 OS: pizza-shaped1
(3) OS: linear lens2Dilated pupil was covered by a white opacity before cataract surgery. A semiclear area in the peripheryLens cortex was completely absorbed (OM-type 3)
(4) OU: linear lens2Dilated pupil was covered by a white opacity before cataract surgery. A semiclear area in the peripheryLens cortex was completely absorbed (OM-type 3)
(5) OD: dumbbell-shaped4Dilated pupil was covered by a white opacity before cataract surgery. A semiclear area in the peripheryLens cortex was mostly absorbed (OM-type 2)
 OS: flying saucer-shaped3
(6) OS: fusiform5Pupil was covered by a daisy-like white opacity in the center before cataract surgery. A semiclear area in the peripheryLens cortex was partially absorbed (OM-type 1)
