Clinical Characteristics and Surgical Procedures for Children with Congenital Membranous Cataract

Figure 2

Operating microscope photographic images for different classifications of cataract. OM-type 1 (a): the cortex was partially absorbed. (A, C) The pupil was covered by a daisy-like white opacity in the central region with a semiclear area in the peripheral region before cataract surgery. (B, D) A clear visual axis appeared in the central pupil after cataract surgery. OM-type 2 (b): the cortex was mostly absorbed (missing). (A, C) The pupil was covered by a white central opacity before cataract surgery with a semiclear periphery. (B, D) A clear visual axis appeared in the central pupil region.OM-type 3 (c): the cortex completely absorbed (missing). (A, C) The dilated pupil was covered by a white opacity before cataract surgery. A semiclear area in the periphery was seen. (B, D) A clear visual axis in the central pupil was achieved. OM-type 4 (d): a few blood vessels were observed. (A) The pupil was covered by a white opacity contained in a central Hemal net before cataract surgery. (B) A clear visual axis in the central pupil was achieved after cataract surgery. OM-type 5 (e): many blood vessels were observed. (A) The pupil was covered by a white opacity. A white opacity containing a central red mass was visible. There were many vessels in the lens. (B) A clear visual axis in the central pupil during cataract removal surgery was observed. (C) A posterior capsule opacification could be seen in the pupil, and a delayed hemorrhage after surgery was observed.
