Long-term evaluation of dexamethasone intravitreal implant in vitrectomized and non-vitrectomized eyes with macular edema secondary to non-infectious uveitis

To compare dexamethasone (DEX) intravitreal implant effect in non-vitrectomized (non-PPV) vs vitrectomized (PPV) eyes with macular edema (ME) secondary to non-infectious uveitis.
Medical records of patients with uveitic ME treated with DEX-intravitreal implant were reviewed. Main outcome measures were changes in central retinal thickness (CRT), best corrected visual acuity (BCVA), intraocular pressure (IOP), vitreous haze and adverse events. Statistical analysis was performed by Longitudinal Linear model using the General Estimating Equation methodology.
Forty-two eyes of 32 patients were included. Median follow-up time was 18 months (interquartile range (IQR): 12–24). Median CRT showed its maximum decrease at the first month in non-PPV and PPV eyes without statistically significant differences between both groups (P=NS). Median Snellen BCVA, converted to logarithm (LogMAR), showed its maximum improvement at third month in both groups without statistically significant differences between them (P=NS). Median IOP was higher in non-PPV eyes than in PPV eyes from third (P=0.025) to 12th month (P=0.013)………
