To assess the efficacy of tumor necrosis factor-alpha inhibitors (TNFi) on uveitic macular edema (ME) unresponsive to conventional synthetic disease-modifying anti-rheumatic drugs (csDMARDs).This multicenter retrospective study included patients with uveitic ME persisting despite csDMARDs. The effect of an additional TNFi on central retinal thickness (CRT), best corrected visual acuity (BCVA) and corticosteroid need was evaluated.Thirty-five eyes (26 patients, mean age 42.9 ± 15.2 years) were included. CRT decreased from 425 ± 137 µm to 294 ± 66 µm (The addition of a TNFi resulted in an improvement of CRT and BCVA for up to 4 years in uveitic ME but rescue treatments were needed for some patients.

Purpose To determine the inherent risks of handling results below the lowest detectable value in the analysis of multiple cytokines in the aqueous humor of patients with retinal diseases by comparing possible statistical strategies to lower the risk of mis interpretation or over interpretation of results. Furthermore, in analyzing multiple cytokines simultaneously, the challenge of multiple comparison arises. Methods The analyses were based on parallel testing of 43 cytokines in 58 aqueous humor samples from patients with macular hole or epiretinal membrane. Substitution of values below the detection limit with 0.1 ×, 0.5 ×, or 1.0× of the lowest level of quantitation was compared with handling as missing value. The impact of correction for multiple comparisons was assessed using the Holm correction. Results When comparing macular hole with epiretinal membrane, not substituting the missing data revealed a difference (P < 0.05) for five compared with wight cytokines after their substitution, indicating an increased risk for under-estimating group differences (type II error). Correcting for multiple comparisons revealed a relevant risk of over estimating group differences (type I error). Conclusions Physiologic cytokine concentrations in ocular fluids typically range at or below the lowest level of quantitation. Handling of results below this cutoff as missing leads to increased type II errors. Not correcting for multiple comparisons increases the risk of a type I error. Taken together, both harbor a systematic inherent risk of misinterpretation of the results. Translational Relevance Ignoring the inherent risks of data misinterpretation in analyses of ocular fluid samples may result in mis leading conclusions regarding their biological relevance.

To report outcomes in patients with neovascular age-related macular degeneration (nAMD) after treatment with aflibercept for up to 4 years using a treat-and-extend (TE) regimen.Observational study.Patients with newly diagnosed nAMD treated with aflibercept in a TE protocol.Subjects received 3 injections of aflibercept at monthly intervals followed by a TE protocol for at least 12 months. At each clinical visit after the loading phase, OCT and best-corrected visual acuity (BCVA) testing were performed to monitor disease activity.Change in BCVA over time, number of injections and visits per year, and percentage of patients reaching a treatment interval of ≥12 weeks.Of 231 consecutive eyes (231 patients) with a mean follow-up time of 2.9 (1-5.5) years, 173 were followed up for ≥2 years, 112 were followed up for ≥3 years, and 62 were followed up for ≥4 years. Mean BCVA increased from 59.8 letters (20/60) at diagnosis to 65.8 letters (20/50) after the loading phase (+6.0 letters; standard deviation [SD], 11.1) and to 65.5 letters at 12 months (+5.7 letters; [SD], 17). After 4 years of treatment, mean BCVA was maintained insignificantly better than baseline (63.4 letters, +3.6 letters gain, SD, 20.6; P 0.05). To achieve this, a mean of 7.7 (±1.2) injections and 4.4 (±1.6) clinic visits in the first year and 4.4 (±1.9) injections and 4.3 (±1.3) clinical visits per year thereafter were required. By 2 years of follow-up, 46.9% of patients reached a treatment interval of ≥12 weeks.By using a TE regimen, patients with nAMD maintained stable visual function over 4 years in a real-world setting with a reasonable treatment burden.

Purpose To identify disease-specific cytokine profile differences in the aqueous humor (AH) (other than the vascular endothelial growth factor) between patients with dry and treated wet age-related macular degeneration (AMD) and healthy controls. Methods This retrospective study drew on a case-series of patients diagnosed with dry AMD (n = 25) and treated wet AMD (n = 19), as well as on healthy controls (no systemic therapy; n = 20) undergoing phacoemulsification or vitrectomy. Samples of AH and serum were collected in parallel at the beginning of surgery. The levels of 43 cytokines were simultaneously determined using the Bio-Plex® multiplex beads system. Differences between the three groups were statistically compared using the Kruskal-Wallis H-Test after applying the Bonferroni correction for multiple comparisons (p
