Introduction: To assess the long-term effectiveness of a treat-and-extend (T&E) anti-vascular endothelial growth factor regimen in patients with neovascular age-related macular degeneration who remain on T&E and those switched from once-monthly (OM) dosing to T&E (OM-T&E). Methods: In this 12-month extension of the 2-year CANTREAT study, patients received intravitreal ranibizumab 0.5 mg in a T&E regimen. Main outcome measures included mean change in best-corrected visual acuity (BCVA) from baseline and from month 24 to month 36; percentages of patients who gained ≥5, ≥10, or ≥15 Early Treatment of Diabetic Retinopathy Study (ETDRS) letters or lost ≥5, ≥10, or ≥15 letters from baseline and from month 24 to month 36; and number of injections administered from baseline and from month 24 to month 36 for both groups. Results: Of the 139 patients (73 T&E, 66 OM-T&E) in the extension, 121 (68 T&E, 53 OM-T&E) completed 36 months. Mean (standard deviation [SD]) BCVA changes from baseline to the extension last visit (month 33-36) were +6.6 (11.4) letters in the T&E group and +4.8 (14.3) letters in the OM-T&E group, representing maintenance of 24-month gains. The mean (SD) numbers of injections during the extension were 7.3 (2.7) for T&E and 7.1 (2.8) for OM-T&E. Discussion/Conclusion: These findings suggest that after 36 months of treatment, the mean BCVA improvement achieved at 24 months is maintained for both the patients exclusively treated with the T&E regimen and those that switched to T&E after 24 months in the OM regimen.

Sector and pericentral are two rare, regional forms of retinitis pigmentosa (RP). While usually defined as stable or only very slowly progressing, the available literature to support this claim is limited. Additionally, few studies have analyzed the spectrum of disease within a particular genotype. We identified all cases (9 patients) with an autosomal dominant Rhodopsin variant previously associated with sector RP (RHO c.316G > A, p.Gly106Arg) at our institution. Clinical histories were reviewed, and testing included visual fields, multimodal imaging, and electroretinography. Patients demonstrated a broad phenotypic spectrum that spanned regional phenotypes from sector-like to pericentral RP, as well as generalized disease. We also present evidence of significant intrafamilial variability in regional phenotypes. Finally, we present the longest-reported follow-up for a patient with RHO-associated sector-like RP, showing progression from sectoral to pericentral disease over three decades. In the absence of comorbid macular disease, the long-term prognosis for central visual acuity is good. However, we found that significant progression of RHO p.Gly106Arg disease can occur over protracted periods, with impact on peripheral vision. Longitudinal widefield imaging and periodic ERG reassessment are likely to aid in monitoring disease progression.

Purpose: Soft drusen and subretinal drusenoid deposits (SDD) aka reticular macular disease (RMD) characterize two pathways to advanced age-related macular degeneration (AMD). We propose these pathways are distinct diseases, with distinct genetic risks, serum risks and associated systemic diseases. Methods: 126 Subjects with AMD had: retinal imaging for RMD status, serum risks, genetic testing, and histories of cardiovascular disease (CVD) and stroke. Results: 62 subjects had RMD, 64 were nonRMD (drusen only), 51 had CVD or Stroke. RMD correlated significantly with: ARMS2 risk allele (p= 0.019); lower mean serum HDL (61 vs. 69 mg/dl, p= 0.038, t test); CVD and troke (34/51 RMD, p= 0.001). NonRMD correlated/trended with: APOE2 (p= 0.032) and CETP (p= 0.072) risk alleles. 97 subjects total had some drusen, which correlated with CFH risk (p= 0.016). Multivariate independent risks for RMD were: CVD and Stroke (p= 0.008), and ARMS2 homozygous risk (p= 0.038). Conclusion: The RMD and soft drusen AMD pathways have distinct systemic associations, serum and genetic risks. RMD is associated with CVD and stroke, ARMS2 risk, and lower HDL; drusen with CFH risk and two lipid risk genes. These pathways appear to be distinct diseases leading to advanced AMD.

Introduction: In 2017, the Royal College of Ophthalmologists UK published ‘The Way Forward’ describing the effects of the ageing UK population on clinical demand for macular conditions. Although one-stop clinics have become accepted standard practice for combined assessment and injections, there is little guidance regarding eventual discharge of patients, and practice varies between clinicians. In 2018, NHS Lothian started a multidisciplinary one-stop clinic involving an Ophthalmologist, a Medical Photographer, a specialist Low Vision Optometrist, and a Low Vision Counsellor. We aimed to detail our experiences of this novel multidisciplinary discharge clinic for advanced macular disease patients. We also aimed to assess patient-reported anxiety and depression outcomes following this clinic. Retrospective data on 60 patients who attended the clinic from August 2018 to January 2019 were collected and included in analysis. Average age at presentation to the clinic was 85.76 ± 8.18 years old and patients had been followed up in the macula clinic for a mean of 4.80 ± 2.43 years prior to attending the clinic. In all, 31 patients responded to a survey on anxiety and depression using the Hospital Anxiety and Depression score (HADS). Three (10%) of the patients reported scores abnormal for anxiety, and there were no abnormal scores for depression. The clinic provides a holistic approach for end-stage macular disease patients and reduces unnecessary macular anti–vascular endothelial growth factor treatments and clinic review appointments. This is especially important now during the coronavirus SARS-CoV-2 global pandemic. This provides significant benefits to capacity for delivery of clinical services and facilitates a safe and supported discharge for patients.
