Background: Fluocinolone acetonide (FAc) implant represents a long-term strategy for the management of diabetic macular edema (DME). Because of the 3-year duration, the careful monitoring of the intraocular pressure (IOP) is necessary. The main aim of the study was to provide quantitative IOP cutoffs associated with the onset of IOP increases. Methods: The study was retrospectively conducted with 2-year of follow-up. We separately considered eyes with good IOP control (Group 1), eyes requiring IOP-lowering medications (Group 2) and eyes undergoing IOP-lowering surgery (Group 3). The statistical analysis assessed Delta% IOP changes over the 2-year follow-up. ROC analysis was performed to detect significant cutoffs associated with Group 2 and Group 3. IOP changes occurring after a previously administered dexamethasone (DEX) implant were also evaluated. Results: We included 48 eyes (48 patients), stratified as follows: Group 1 (25/48; 52%), Group 2 (19/48; 40%) and Group 3 (4/48; 8%). ROC analysis performed on IOP values detected 2-months later DEX implant showed a mean Delta IOP increase >24% significantly associated with IOP-lowering medications after FAc implant, whereas a mean Delta IOP increase >35% was significantly associated with IOP-lowering surgery after FAc implant. With respect to IOP changes occurred after FAc implant, our ROC analysis showed a mean Delta IOP increase >8% significantly associated with IOP-lowering medications, whereas a mean Delta IOP increase >15% was significantly associated with IOP-lowering surgery. DEX-related IOP changes showed 52% sensitivity and 100% specificity of FAc-related IOP increases. Conclusions: IOP changes provides clinically relevant cutoffs associated with the onset of FAc-related IOP increases.

Abstract

Background: Fluocinolone acetonide (FAc) implant represents a long-term strategy for the management of diabetic macular edema (DME). Because of the 3-year duration, the careful monitoring of the intraocular pressure (IOP) is necessary. The main aim of the study was to provide quantitative IOP cutoffs associated with the onset of IOP increases. Methods: The study was retrospectively conducted with 2-year of follow-up. We separately considered eyes with good IOP control (Group 1), eyes requiring IOP-lowering medications (Group 2) and eyes undergoing IOP-lowering surgery (Group 3). The statistical analysis assessed Delta% IOP changes over the 2-year follow-up. ROC analysis was performed to detect significant cutoffs associated with Group 2 and Group 3. IOP changes occurring after a previously administered dexamethasone (DEX) implant were also evaluated. Results: We included 48 eyes (48 patients), stratified as follows: Group 1 (25/48; 52%), Group 2 (19/48; 40%) and Group 3 (4/48; 8%). ROC analysis performed on IOP values detected 2-months later DEX implant showed a mean Delta IOP increase >24% significantly associated with IOP-lowering medications after FAc implant, whereas a mean Delta IOP increase >35% was significantly associated with IOP-lowering surgery after FAc implant. With respect to IOP changes occurred after FAc implant, our ROC analysis showed a mean Delta IOP increase >8% significantly associated with IOP-lowering medications, whereas a mean Delta IOP increase >15% was significantly associated with IOP-lowering surgery. DEX-related IOP changes showed 52% sensitivity and 100% specificity of FAc-related IOP increases. Conclusions: IOP changes provides clinically relevant cutoffs associated with the onset of FAc-related IOP increases.
