Ocular fundus was examined by binocular indirect ophthalmoscopy in the operating room immediately following delivery of the lens in 56 cataract operations. Significant infoldings of the sclera, choroid, and retina were observed in 84% of eyes in which visualization of the fundus was satisfactory.
These infoldings resembled the buckles of scleral buckling operations for retinal detachment. They were circumferential or radial or both. They could be made to flatten or disappear by external pressure on the anterior sclera or by injection of saline into the anterior chamber. When they disappeared, there was no evidence of choroidal detachment.
The photographs and the data presented indicate that immediately after cataract extraction the ocular fundus develops no detachment of the choroid, but the fundus develops infoldings involving all three posterior coats of the globe.
