Purpose: To analyse the morpho-functional outcomes of dexamethasone intravitreal implant (Ozurdex) injected after lens surgery in diabetic patients with coexisting cataract and macular oedema. Methods: This is a non-randomized, perspective, single-group study on 17 eyes with a diagnosis of cataract and early and advanced diabetic macular oedema. All eyes underwent combined phacoemulsification and Ozurdex injection at the end of surgery and morpho-functional outcomes were analysed in 3 months follow-up. Results: Foveal thickness decreased significantly from 349.6 ± 19.8 (95% CI) at baseline to 310.7 ± 17.5 (95% CI) 90 days after surgery ( p < 0.01). Mean BCVA (LogMAR) improved significantly from 0.38 ± 0.08 (95% CI) at baseline to 0.15 ± 0.06 (95% CI) after 90 days ( p < 0.01). Any ocular or systemic complications were observed during follow-up. Conclusions: Dexamethasone intravitreal implant combined with phacoemulsification may be safe and effective to improve morpho-functional outcomes in diabetic patients with coexisting cataract and macular oedema.

Abstract Purpose: To investigate the efficacy and safety of dexamethasone intravitreal implant in the treatment of relapsing posterior uveitis in patients with chronic recurrent VKH disease.Methods: This is a prospective study of 29 eyes of 16 patients with posterior uveitis in chronic recurrent VKH disease. All patients received previous systemic steroid and immunosuppressive regimens. All patients underwent a comprehensive ophthalmic examination, including BCVA (log MAR), IOP, FFA, and SD-OCT. All patients underwent intravitreal injection with sustained-release dexamethasone 0.7 mg implant (Ozurdex®). Primary outcome measures included mean change in best corrected visual acuity (BCVA) and central foveal thickness (CFT) at 24 months follow-up compared to baseline. Results: At 24 months follow-up, the mean BCVA improved from 0.82 ± 0.13 to 0.38 ± 0.06logMAR (P <0.0001). The mean CFT reduced from 505 ± 29 to 244 ± 23 um (P <0.0001). The mean IOP changed from 15.1±2.2 to16.9±3.1 mmHg with no significant value. Twenty-one eyes (72.4%) received one injection, while eight eyes (27.6%) required two injections. The mean number of injections was 1.2± 0.60. The mean follow-up time was 24.75± 0.9months. No serious ocular or systemic adverse events were noted during the follow-up period. Ocular hypertension was recorded in there (10.3%) eyes and controlled by IOP lowering medications. Cataract progression occurred in 11 (37.9%) eyes.Conclusions: Our cohort highlights the beneficial effects of the Dexamethasone implant 0.7 mg in the treatment of VKH disease relapsing posterior uveitis improving visual acuity, reducing macular edema, and minimizing the burden of systemic steroid in this sample study.

Purpose To determine the potential role of intraoperative dexamethasone intravitreal implant (DEX-I) in reducing diabetic macular edema (DME) worsening after phacoemulsification. Methods This was a prospective study on 19 eyes of 19 patients with type 2 diabetes mellitus with DME and cataract. Mean preoperative Early Treatment Diabetic Retinopathy Study visual acuity (VA) was 16.7 letters. Mean foveal thickness (FT) was 451 μm. The DME was naive in 11 eyes and refractory in 8 eyes. All eyes underwent a standard phacoemulsification and intraocular lens implantation; DEX-I was injected at the end of surgery. Follow-up was performed at 1 week and then monthly until DME recurrence (up to 8 months). Results At 1 week, mean VA improved by 15 letters (range 0-29 letters) and mean FT decreased by 147 μm (range 69-236 μm). Improvement consolidated at month 1, with a mean VA improvement of 18 letters (range 3-32 letters) and a mean improvement in FT of 193 μm (range 76-304 μm), remaining stable at month 2 after surgery in all eyes. The DME recurred in 1 eye at month 3, in 14 eyes (73.8%) between months 4 and 5, and after month 6 in 4 eyes (21%). Refractory DMEs demonstrated the same benefit but recurred earlier than naive ones (4 months versus 5.8 months, p<0.01). Conclusions Intraoperative DEX-I prevents DME worsening after phacoemulsification. Its positive effects last for at least 3 months.

No studies have yet evaluated jointly central foveal thickness (CFT) and the presence of intraretinal fluid (PIF) to diagnose diabetic macular oedema (DMO) using optic coherence tomography (OCT). We performed a cross-sectional observational study to validate OCT for the diagnosis of DMO using both CFT and PIF assessed by OCT (3D OCT-1 Maestro). A sample of 277 eyes from primary care diabetic patients was assessed in a Spanish region in 2014. Outcome: DMO diagnosed by stereoscopic mydriatic fundoscopy. OCT was used to measure CFT and PIF. A binary logistic regression model was constructed to predict the outcome using CFT and PIF. The area under the ROC curve (AUC) of the model was calculated and non-linear equations used to determine which CFT values had a high probability of the outcome (positive test), distinguishing between the presence or absence of PIF. Calculations were made of the sensitivity, specificity, and the positive (PLR) and negative (NLR) likelihood ratios. The model was validated using bootstrapping methodology. A total of 37 eyes had DMO. AUC: 0.88. Positive test: CFT ≥90 µm plus PIF (≥310 µm if no PIF). Clinical parameters: sensitivity, 0.83; specificity, 0.89; PLR, 7.34; NLR, 0.19. The parameters in the validation were similar. In conclusion, combining PIF and CFT provided a tool to very precisely discriminate the presence of DMO. Similar studies are needed to provide greater scientific evidence for the use of PIF in the diagnosis of DMO.

AimTo evaluate the effectiveness of dexamethasone intravitreal implant 0.7 mg (DEX; Ozurdex) monotherapy in the patient subgroup of the AUSSIEDEX study with treatment-naïve diabetic macular oedema (DME).MethodsThe open-label, prospective, phase 4, real-world study included pseudophakic eyes and phakic eyes scheduled for cataract surgery that were treatment-naïve or non-responsive to antivascular endothelial growth factors. No eyes were excluded based on baseline best-corrected visual acuity (BCVA) or central subfield retinal thickness (CRT). After the initial DEX injection at the baseline visit, reinjection was permitted at ≥16-week intervals. Week-16 and week-52 visits were mandatory. Primary endpoints were changes in mean BCVA and CRT from baseline to 52 weeks.ResultsOf 200 eyes enrolled in the AUSSIEDEX study, 57 were treatment-naïve. Baseline mean BCVA was 58.8 letters and baseline mean CRT was 418.6 µm; changes in mean BCVA and CRT from baseline to 52 weeks in this subgroup were 3.4 letters (p=0.042) and –89.6 µm (p<0.001), respectively, with a mean 2.5 injections. The change in mean CRT from baseline was –55.8 µm at week 16 (p<0.001). The most common adverse event was increased intraocular pressure (IOP), with 20.0% of eyes requiring IOP-lowering medication. One patient was discontinued due to increased IOP. No eyes required filtration surgery. No serious, treatment-related ocular adverse events were reported.ConclusionIn this largest prospective, real-world study of DEX monotherapy for DME to date, DEX significantly improved CRT and BCVA at 52 weeks in treatment-naïve eyes, without new safety concerns, supporting DEX use in treatment-naïve DME.Trial registration numberNCT02731911.

Diabetic macular oedema (DMO) is the main cause of vision loss in diabetic retinopathy. The ILUVIEN® intravitreal implant, which contains fluocinolone acetonide and is administered by injection into the vitreous cavity, should be considered if the patient is not responding to anti-vascular endothelial growth factor (VEGF) therapy, and the patient fulfils the recommendations of the National Institute for Health and Care Excellence (NICE) Technology Appraisal 301. The efficacy and safety of the ILUVIEN implant has been demonstrated in clinical studies, and a pre-planned subgroup analysis has shown that it is particularly beneficial in patients with chronic DMO. This case study is the first report in the UK of the effectiveness of the ILUVIEN implant in a patient in whom therapy with ranibizumab did not result in sustained improvements in terms of visual outcomes and foveal thickness.

Background In late 2015, cut-off points were published for foveal thickness to diagnose diabetic macular oedema taking into account the presence of intraretinal fluid using optical coherence tomography (OCT) in primary care patients (90 µm in the presence of intraretinal fluid and 310 µm otherwise). Methods This cross-sectional observational study was carried out on 134 eyes of diabetic patients treated in specialised ophthalmology services in a Spanish region in 2012–2013, to externally validate the aforementioned cut-off points. The main variable (Clinical Standard) was the diagnosis of macular oedema through indirect ophthalmoscopy and posterior segment slit-lamp biomicroscopy. As validation variables, both the foveal thickness and the presence of intraretinal fluid obtained by OCT were used. Validation was performed using bootstrapping by calculating the area under the ROC curve (AUC), sensitivity, specificity, positive likelihood ratio (PLR) and negative likelihood ratio (NLR). Results Forty-one eyes presented diabetic macular oedema (30.6%). The bootstrapping validation parameters were: AUC, 0.88; sensitivity, 0.75; specificity, 0.95; PLR, 14.31; NLR, 0.26. These values were very similar to those of the original publication. Conclusion We have externally validated in specialised care patients the cut-off points published for the diagnosis of diabetic macular oedema. We suggest that others carry out validation studies in their communities.
