Case Report:
A 78-year-old man with phakic eyes underwent photodynamic therapy followed by intravitreal injection of triamcinolone. During the injection a white solution was observed in the anterior chamber. Slit lamp examination revealed white opacities in the inferior anterior chamber angle and neither inflammatory activity nor corneal changes were noticed.
Discussion:
Intravitreal triamcinolone has been used for treating macular edema and various retinal vascular and inflammatory diseases. We describe the passage of triamcinolone to the anterior chamber during the injection in a phakic eye as a very unusual adverse effect, observed probably as a result of a zonular defect.
