Subretinal triamcinolone acetonide associated with improvement of cystoid macular edema in a patient with retinitis pigmentosa.

OBJECTIVE

To report a case of traumatic displacement of intravitreal triamcinolone acetonide into the subretinal space.

METHODS

Single case report.

RESULTS

We describe a 17-year-old boy with retinitis pigmentosa and severe, persistent cystoid macular edema with foveal cysts resistant to surgical intervention who had marked clinical improvement after traumatic displacement of intravitreal triamcinolone acetonide into the subretinal space.

CONCLUSIONS

Subretinal delivery of triamcinolone acetonide may be more effective than preretinal steroid administration in reducing foveal cysts, particularly in retinitis pigmentosa. In this case, the duration of triamcinolone acetonide in the subretinal space seemed to be on the order of 3 months.
