abstract = {Retinitis pigmentosa (RP) is a leading cause of blindness.
The best studied modelsof human RP are the rd1 and rd10
mouse and the RCS rat (Royal College of Surgeons).In many
models after degeneration of the photoreceptors, a
pathologicalrhythmic activity of the retina as well as
lowered efficiency of electrical stimulationwere observed.
In rd10 retina, both events were shown to be intimately
linked. Surprisingly,to our knowledge no retinal
oscillations have been reported in RCS retina.As
oscillations might interfere with the performance of
therapeutic approaches torestore vision, e.g., retinal
prostheses, it is important to know, whether they are
acommon feature of retinal degeneration. Electrical activity
was recorded in retinaeof 3–19 months (M3-19) old RCS rats
in vitro using planar and penetrating multielectrode-arrays.
Short deflections in the local field potential resembling
thoseobserved in oscillations in rd1 and rd10 retinae were
only sporadically found inM3 RCS retinae. Oscillations at
appr. 2 Hz occurred more often and were morepronounced the
older the animals were. Yet, even at M18-19 oscillatory
periodswere short and separated by long periods of
non-oscillatory activity. In summary, inadvanced stages of
degeneration, RCS retinae display oscillations similar to
rd1 andrd10 retinae. However, in RCS retina oscillatory
periods are shorter than in mousemodels and may, therefore,
have escaped detection in earlier studies. These
resultstogether with results observed in non-rodent models
suggest that pathological rhythmicactivity is a common
feature in RP models.},
