Does corneal grafting alter the electroretinogram?
Ten patients who required corneal graft operations and who had normal retinal function were examined by standardized electroretinography preoperatively and on two occasions postoperatively. No significant change was observed when the various preoperative and postoperative responses were compared. Thus, corneal grafting per se does not affect the electroretinogram. Electrophysiologic tests have been used to assess retinal function in the presence of opaque media. An important consideration in any such measurements is the effect of the opaque media themselves on the response.
