The present study evaluated alterations in the focal electroretinogram (FERG) in cases of retinal detachment and spontaneous reattachment in 11 ablino rabbits. FERGs were obtained under direct visualization of the fundus by an infrared television fundus camera with a light stimulator. The pre-operative b-wave amplitude al1c. implicit time were 0.52 +/- 0.07 micro V and 59.7 +/- 4.1msec (mean +/- S.D.), respectively. Thirty minutes after making the retinal detachment, the amplitude decreased significantly to 0.08 +/- 0.09 micro V (p Rabbits ; Retina ; Retinal Detachment* ; Retinaldehyde* ; Television
