1/3. Reactivation of ocular toxoplasmosis after LASIK.

    PURPOSE: To report a reactivation of ocular toxoplasmosis after LASIK. methods: Case report of a 34-year-old man who underwent bilateral LASIK. The posterior segment examination revealed an old toxoplasmosis scar in the retinal periphery of the right eye. RESULTS: Uncorrected visual acuity improved postoperatively, and the patient was satisfied. However, 52 days after the procedure, he complained of loss of visual acuity in his right eye. Examination revealed signs of anterior uveitis, vitreitis, and active chorioretinal lesion satellite of the old toxoplasmosis scar. The patient was treated with a multidrug regiment with resolution of the vitreous and lesion activity. CONCLUSIONS: toxoplasmosis reactivation may develop after LASIK.

2/3. 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 toxoplasmic retinochoroiditis. methods: The authors analysed the evolution of ICG satellite dark dots in two cases of recurrent toxoplasmic retinochoroiditis receiving anti-toxoplasmic treatment not including corticosteroids. RESULTS: Both patients had a recurrence on the peripheral aspect of scars from previous retinochoroiditis and were treated with pyrimethamine (50 mg/day) and sulfadiazine (4 g/day) for seven weeks. Resolution 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 treatment not including corticosteroids tends to indicate that there is probably an infectious component in these hypofluorescent dots and that they probably do not represent a purely inflammatory perilesional reaction.

3/3. Toxoplasmic retinochoroiditis: resolution without treatment of the perilesional satellite dark dots seen by indocyanine green angiography.

    PURPOSE: Satellite dark dots (SDD) seen by indocyanine green angiography (ICGA) around the main retinochoroiditis focus are described in 75% of cases. Whether SDDs represent subclinical infectious foci or just a perilesional inflammatory reaction is not known. The purpose here was to report a case giving additional information on this question. methods: We analysed the evolution of ICGA SDDs in a patient with recurrent toxoplasmic retinochoroiditis who received no antitoxoplasmic treatment because the lesion was located outside the areas where treatment is classically recommended. RESULTS: The patient had a recurrence of retinochoroiditis on the nasal aspect of the disc about 2 disc diameters away from the disc. It was decided to observe the recurrence before introducing treatment. Diminution of SDDs occurred by 3 weeks after the initial ICGA, and complete resolution was observed on a follow-up ICG angiogram obtained 8 weeks after the initial visit. CONCLUSION: Resolution of ICGA SDDs in toxoplasmic retinochoroiditis seems to occurring a similar fashion whether or not the retinochoroiditis is treated by anti-toxoplasmic drugs, indicating that SDDs probably represent a non-infectious perilesional inflammatory reaction.
