Bilateral cataracts were detected in a group of aquarium-raised tilapia (Sarotherodon mossambicus). Vision impairment was manifested as random swimming into objects, but the fish appeared to function normally otherwise. Most of the lens was opaque, with the outer extent of the cortex and subcapsular region remaining transparent. Skeletal abnormalities, ie, deformed fins, abnormal jaws, and curvature of the spine, were observed in affected individuals. Histologically, there was progressive degeneration of the cataractous portion as the affected fish matured. Preliminary breeding experiments indicated that the condition may be inherited.
在一组人工养殖的罗非鱼(莫桑比克罗非鱼)中发现了双侧白内障。视力障碍表现为随机游向物体,但这些鱼在其他方面似乎功能正常。大部分晶状体不透明,皮质和囊下区域的外部仍保持透明。在受影响的个体中观察到骨骼异常,即鳍变形、颌异常和脊柱弯曲。组织学上,随着受影响的鱼成熟,白内障部分会逐渐退化。初步的育种实验表明这种情况可能是可遗传的。
