Abstract
INTRODUCTION
Intravitreal dexamethasone (DEX) implant is indicated for the treatment of macular oedema due to diabetic retinopathy, retinal vein occlusion and uveitis. The most common complications are cataract and elevated intraocular pressure (IOP). Accidental injection of DEX implant into the lens is a rare complication and only few papers presented it.
CASE PRESENTATION
A 40-year-old man was treated with DEX implant for diabetic macular oedema in both eyes. At 1 week follow-up visit, slit lamp examination showed the DEX implant was located in the crystalline lens of the right eye (RE) without any sign of inflammation, cataract or elevated IOP, so we decided to plan a normal follow-up schedule. Macular oedema relapsed 5 months after the injection in the left eye (LE), whereas the RE did not show any sing of intraretinal or subretinal fluid. Six months after DEX implantation an uneventful phacoemulsification and intraocular lens placement were performed in the RE because of IOP elevation.
CONCLUSIONS
The therapeutic effect of DEX implant can be maintained for a longer period of time than intravitreal implant, determining complete reabsorption of macular oedema. Intralenticular implant can be maintained inside the lens until either IOP increases, cataract progresses, or other complications occur.
