RECURRENT TOXOPLASMIC RETINOCHOROIDITIS - SIGNIFICANCE OF PERILESIONAL SATELLITE DARK DOTS SEEN BY INDOCYANINE GREEN ANGIOGRAPHY

Purpose: To suggest an explanation for the satellite dark dots seen by indocyanine green angiography (ICGA) around the main focus of a toxop lasmic retinochoroiditis. Methods: The authors analysed the evolution of ICG satellite dark dots in two cases of recurrent toxoplasmic retin ochoroiditis receiving anti-toxoplasmic treatment not including cortic osteroids. Results: Both patients had a recurrence on the peripheral a spect of scars from previous retinochoroiditis and were treated with p yrimethamine (50 mg/day) and sulfadiazine (4 g/day) for seven weeks. R esolution of satellite ICG dark dots was observed in both cases on the follow-up ICG angiogram performed at the end of treatment. Conclusion : Resolution of ICG satellite dark dots after anti-toxoplasmic treatme nt not including corticosteroids tends to indicate that there is proba bly an infectious component in these hypofluorescent dots and that the y probably do not represent a purely inflammatory perilesional reactio n.
