Abstract

Purpose: To compare the efficacy of intravitreal CLINDAMYCIN and DEXAMETHASONE with classic treatment for OCULAR TOXOPLASMOSIS.Methods: In this prospective, randomized single-masked clinical trial a total of 68 patients with active OCULAR TOXOPLASMOSIS were assigned randomly to 2 treatment groups: 34 in the intravitreal CLINDAMYCIN plus DEXAMETHASONE (IVCD) group and 34 in the classic treatment (CT) group. The IVCD group received 1 to 3 injection (s) of 1 mg intravitreal CLINDAMYCIN and 400 mg DEXAMETHASONE, and the CT group received 6 weeks of treatment with pyrimethamine and sulfadiazine plus prednisolone. Antitoxoplasmosis antibodies (immunoglobulin [Ig] M and IgG) were measured using an enzyme-linked immunosorbent assay.Results: The mean number of injections in the IVCD group was 1.6. Lesion size reduction was statistically significant after treatment in both IVCD and CT groups (P<0.001 and P:0.009, respectively). The difference in mean percentage of reduction at 6 weeks was not significant: 57±27.6% in the IVCD group versus 58.4±29.3% in the CT group. In comparison to baseline, VA increased by 0.44±0.24 and 0.29±0.19 logarithm of the minimum angle of resolution units in the IVCD and CT groups, respectively (P<0.001); however, the difference in VA improvement between the groups was not significant. The interaction effect of IgM and treatment group on lesion size reduction was significant (P=0.002); this indicated that IgM-positive cases responded better to CT and IgM-negative cases responded better to IVCD treatment. Vitreous inflammation reduction was comparable between the groups. Within 2 years, 4 eyes (2 in each group) had 1 episode of recurrence. Adverse drug reactions occurred in 2 patients in the CT group. No major injection-related complication was encountered in the IVCD group.Conclusion: Intravitreal injection of CLINDAMYCIN and DEXAMETHASONE may be an acceptable alternative to classic treatment in OCULAR TOXOPLASMOSIS. It may offer more convenience, a safer systemic profile, greater availability, and fewer follow-up visits and hematologic evaluations.
