[Regeneration capacity in retina and vitreous body changes following extraction of intravitreal copper particles].

On the basis of experiments with 42 rats, quantitative statements are made regarding the influence of surface area and dwelling time of intravitreal copper particles on the electroretinogram. The influence of these factors on the extent of recovery of function after extraction of the foreign body is demonstrated. The rate of mental intoxication (metallosis retinae) is indicated separately from the mechanical damage. Ophthalmoscopic findings are also described. The practical relevance of these results to the clinical situation is discussed in detail in connection with earlier reports.
