Treating Diabetic Macular Oedema (DMO): real world UK clinical outcomes for the 0.19mg Fluocinolone Acetonide intravitreal implant (Iluvien™) at 2 years.

BACKGROUND: To compare visual function and structural improvements in pseudophakic eyes with diabetic macular oedema (DMO) treated with the 0.19mg Fluocinolone Acetonide (FAc) intravitreal implant (IluvienTM) in a 'real world' setting. METHODS: A single centre retrospective evaluation of patients with DMO unresponsive to conventional treatment treated with the FAc implant according to UK guidelines. Primary efficacy endpoint was best corrected visual acuity (BCVA); secondary endpoints included optical coherence tomography evaluations of the macula (a) central retinal and (b) peak macular thickness collected at annual time points. Primary safety endpoint was new rise in IOP >27mmHg or glaucoma surgery. Patients with <1 year follow-up were excluded. RESULTS: Twenty-nine eyes were included, with mean(SD) follow up of 792(270) days. Improvement in BCVA and reduction in macular oedema was noted at all timepoints. Mean improvement in BCVA from baseline was 6 ETDRS letters at year 1(n=29), 6.5L at year 2(n=22) and 11L at year 3(n=6). Mean central retinal thickness at baseline was 451 microns, 337 microns at year 1, 342 microns at year 2 and 314 microns at year 3. Two eyes required IOP-lowering drops post implant. Supplementary treatment for persistence or recurrence of DMO was necessary in 18 eyes over the total study period of 3 years with mean time to supplementary treatment being 12 months. CONCLUSIONS: Our evaluation of the 0.19mg FAc implant delivered in a real-world setting, provides additional evidence that it is effective and safe in the treatment of patients with DMO, and can provide sustained benefit for patients with previously refractory disease.

Identifying early symptoms of choroidal neovascularisation in second eyes of patients with unilateral wet age related macular degeneration using a telephone evaluation method.

BACKGROUND/OBJECTIVES: Patients undergoing intravitreal injections for nAMD are often anxious about early detection of nAMD in their fellow eyes. The purpose of this study was to evaluate a home-based telephone method for helping patients to monitor for symptoms of second eye involvement. SUBJECTS/METHODS: Using a five-staged evaluation tool, telephone-assisted evaluations were repeatedly performed on the patients' fellow eyes every 4 weeks for 1 year. A decision on presence or absence of nAMD was made after each telephone evaluation. Slitlamp examination and OCT scan were performed at 3, 6, 9 and 12 months or whenever nAMD was suspected from the telephone evaluation. The sensitivity and specificity values were calculated from the true and false positive and negative rates of each of the five composite stages. RESULTS: In total, 514 telephone episodes comprising 2570 evaluations were conducted on fellow eyes of 50 patients over one year. Three patients (6%) developed nAMD in fellow eyes. The sensitivity of all of the stages was low (33.3%). The specificity of the five stages ranged from 91.3% to 98.6%. The highest specificity was achieved by the near acuity component of the tool. CONCLUSIONS: We were unable to demonstrate a high sensitivity for the five-staged tool but the near acuity component of this tool had a very high specificity. This could have potential for "ruling out" nAMD and reducing the burden of false positive episodes for a large group of patients who are at risk of developing nAMD in their second eyes.

Comparing Effectiveness of Three Different Anti-VEGF Treatment Regimens for Neovascular Age-Related Macular Degeneration: Two Years' Real-World Clinical Outcomes.

PURPOSE: To compare and report the 2-year treatment outcomes from 3 different anti-VEGF treatment regimens in treating neovascular aged-related macular degeneration (nAMD): Ranibizumab pro re nata (Ranibizumab-PRN); Ranibizumab treat and extend (Ranibizumab-T&E); Aflibercept fixed first year dosing (7 injections) with treat and extend in subsequent year (Aflibercept-Fixed). METHODS: All treatment-naïve nAMD patients who completed 24 months of monitoring from a single treatment center were included. Patients received the initial loading dose of three injections (4-weekly interval), followed by one of the 3 treatment regimens. Primary outcomes were changes in visual acuity (VA) and central retinal thickness (CRT). Secondary outcome was number of injections required in each year. Data analysis included last observation carried forward (LOCF) for patients with incomplete year-2 follow-up. RESULTS: A total of 249 eyes (230 patients) were studied: 121 Ranibizumab-PRN; 65 Ranibizumab-T&E, and 63 Aflibercept-Fixed. Baseline median VA (ETDRS letters) for Ranibizumab-PRN, Ranibizumab-T&E, and Aflibercept-Fixed was 53.9, 61.1, and 54.9 letters, achieving final VA of 54.9, 65.1, and 65.1 letters, respectively. Hence, the number of letters increased at the end of 24 months for each group was +1.0 (Ranibizumab-PRN), +4.0 (Ranibizumab-T&E), highest +10.2 in Aflibercept-Fixed group. Median number of injections over 2 years (year-1/year-2) was 5/1 for Ranibizumab-PRN, 9/6 for Ranibizumab-T&E, and 7/5 for Aflibercept-Fixed. Both Ranibizumab-T&E and Aflibercept-Fixed also shared the same reduction of median CRT (115 µm), higher than Ranibizumab-PRN (83 µm). CONCLUSION: We report VA improvement from all three different treatment regimens with both Aflibercept-Fixed and Ranibizumab-T&E regimens achieving the same higher final VA. Aflibercept-Fixed dosing may have more favorable efficacy with the highest VA gain and comparatively lower dosing frequency whereas Ranibizumab-T&E may be more efficient than Ranibizumab-PRN regimen, according to our study.

Oral medications for central serous chorioretinopathy: a literature review.

Central serous chorioretinopathy (CSCR) is characterised by acute or chronic neurosensory detachments of the retina, usually in the posterior pole, with or without associated detachments of retinal pigment epithelium. Although the condition often resolves spontaneously, chronic and recurrent cases can lead to significant visual loss in the working population and it is thus increasingly recognised as an important public health issue. The uncertainty regarding the underlying cause of CSCR has led to a wide range of therapies being tried for this condition including photodynamic therapy, laser photocoagulation, anti-VEGF injections and a multitude of oral agents. This article aims to review the current evidence for oral agents that have been used for treatment of CSCR. A systematic literature search was conducted for articles published between 1980 to July 2018. A total of 73 articles were included. These studied the following oral medications: eplerenone, spironolactone, beta blockers, H. pylori agents, omeprazole, rifampicin, methotrexate, aspirin, acetazolamide, mifepristone, melatonin, finasteride, ketoconazole, antioxidants and curcumin phospholipid. Although none of the studies showed robust evidence of efficacy, the mineralocorticoid receptor antagonists, particularly eplerenone, appear to demonstrate the highest quality evidence for use in this condition. The review aims to give the reader an overview of the current available evidence for oral medications used in the treatment of CSCR in order to provide an evidence-based discussion with the patient and guide through possible options for treatment.

Iluvien™ (Fluocinolone Acetonide 0.19 mg Intravitreal Implant) in the Treatment of Diabetic Macular Edema: A Review.

Diabetic macular edema (DMO) is a leading cause of blindness in the working age population. Although anti-vascular endothelial growth factor (VEGF) therapy provided a major advance in treatment of DMO for many patients, there is a significant proportion of patients who maintain persistent DMO and have minimal response to anti-VEGF treatment. Iluvien (fluocinolone acetonide 0.19 mg [FAc]) is an important additional treatment option for DMO. In this review we describe the clinical context and the evidence for the use of the FAc implant in treating DMO, from pilot to randomized controlled studies, to later phase real world data. These studies indicate that the FAc implant is effective, well tolerated and a cost-effective option in the treatment of insufficiently responsive DMO.

Retinal embolic events: frequency and impact following transcatheter aortic valve implantation (TAVI) for aortic stenosis.

OBJECTIVES: Transcatheter aortic valve implantation (TAVI) is an established treatment for patients with severe symptomatic aortic stenosis. It has a cerebrovascular accident rate of about 5% but the effect on retinal embolic events has not been previously reported. This study investigated the occurrence of retinal emboli following TAVI. METHODS AND ANALYSIS: In this prospective observational study, 20 patients underwent full ophthalmic examination to assess retinal embolic events prior to TAVI and at 48 hours and 1 month post-TAVI. RESULTS: At 48 hours post-TAVI, one patient had a new cotton wool spot in the right eye. At 1 month, another two patients had new retinal emboli events in at least one eye and a fourth patient developed retinal splinter haemorrhages in the right eye. CONCLUSION: Retinal embolic events and new retinal abnormalities following TAVI occurred in 15% and 20% of our cohort, respectively, without any associated retinal damage or significant visual problems. Retinal evaluation may be a useful surrogate test for cerebral embolisation in future studies assessing the utility of new valve prostheses and embolic protection devices.
