Abstract
INTRODUCTION To evaluate the detection rate of aneurysmal type 1 neovascularization (AT1) in Caucasian patients using optical coherence tomography angiography (OCTA) and to describe OCTA characteristics of AT1 in a cohort of white patients. METHODS We conducted an observational retrospective study in 44 eyes of 43 patients with AT1. All patients underwent a complete ophthalmologic examination, including fundus imaging, indocyanine green angiography, optical coherence tomography, and OCTA. Branching vascular network (BVN) and polyp detection rates by OCTA were evaluated. Furthermore, we described BVN and polyp morphologies on en face OCTA and flow of polyps on B-scan OCTA. RESULTS En face OCTA revealed BVN in 84.09% of cases and polypoidal lesions in 86.36% of cases. B-scan OCTA showed BVN and polyps in 95.45% and 93.18% of the patients, respectively. "Trunk" BVNs (51.35%) and "ring" polyps (47.37%) were the most frequent morphologies observed in our cohort, and "patchy hyperflow" (80.49%) signal was the most common visualized in our patients. Regarding OCT parameters, CT under polyps was higher in patients with positive detection of polyps on B-scan OCTA. CONCLUSION OCTA is a possible diagnosis tool in Caucasian patients with AT1. To the best of our knowledge, this is the largest study performed in Caucasian patients regarding OCTA diagnostic abilities and features.

Abstract
INTRODUCTION There are a few reports investigating the treatment of aneurysmal type 1 neovascularization (AT1) in Caucasian patients. The aim of this study is to evaluate the 2-year results of a treat and extend regimen with aflibercept in Caucasian patients with AT1. METHODS We conducted an observational retrospective study in 28 eyes of 26 patients with naïve AT1 treated with a treat an extend regimen of intravitreal aflibercept. Best corrected visual acuity (BCVA), central macular thickness (CMT), pigment epithelium detachment (PED) height, presence of dry macula, and regression rate of polypoidal lesions were assessed at baseline and at 12 and 24 months. RESULTS BCVA was significantly increased by 9.03 ± 16 letters (p < 0.01) and 9.2 ± 16.87 letters (p < 0.01) after the 12 and 24 months follow-up. A significant decrease of CMT was found at 12 and 24 months (p < 0.01). Nevertheless, significant changes in PED height were not observed (0.1 < p > 0.05). At 12 and 24 months of follow-up, dry macula was achieved in a total of 10 eyes (35.71%) and 15 eyes (53.57%). The regression rate of polypoidal lesions was 25% (7 eyes) and 35.71% (10 eyes) after 12 and 24 months. The mean number of intravitreal injections was 7.81 ± 3.20 the first year and 6.11 ± 3.49 the second year. CONCLUSION To the best of our knowledge, treat and extend regimen with intravitreal aflibercept in Caucasian patients may be effective for improving BCVA, CMT, wet macula, and regression rate of polypoidal lesions.

Phenotypic and genetic variations between Asian and Caucasian polypoidal choroidal vasculopathy. Br J Ophthalmol 2020; 105:1716-1723. [PMID: 33037006 DOI: 10.1136/bjophthalmol-2020-317537] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/21/2020] [Revised: 09/07/2020] [Accepted: 09/13/2020] [Indexed: 11/03/2022]
Abstract
PURPOSE To compare phenotypic and genetic variations in polypoidal choroidal vasculopathy (PCV) between Caucasian and Asian patients. METHODS We analysed phenotypic and genotypic data from two sites, Association for Innovation and Biomedical Research on Light and Image, Portugal and Singapore National Eye Centre, Singapore. Baseline fundus photography, spectral domain-optical coherence tomography, indocyanine green and fluorescein angiography scans were analysed by respective reading centres using a standardised grading protocol. Single nucleotide polymorphisms across 8 PCV loci were compared between cases and controls selected from each population. RESULTS One hundred and forty treatment-naïve PCV participants (35 Portuguese and 105 Singaporean) were included. The Portuguese cohort were older (72.33±8.44 vs 68.71±9.40 years, p=0.043) and were comprised of a lower proportion of males (43% vs 71%, p=0.005) compared with the Singaporean cohort. Differences in imaging features include higher prevalence of soft drusen (66% vs 30%, p=0.004), lower prevalence of subretinal haemorrhage (14% vs 67%, p<0.001), smaller polypoidal lesion (PL) area (0.09±0.09 vs 0.76±0.93 mm2, p<0.001), lower ratio of PL to branching vascular network area (3% vs 38%, p<0.001) and lower central retinal thickness (346.48±93.74 vs 493.16±212.92 µm, p<0.001) in the Portuguese cohort. CETP rs3764261 (OR 2.467; 95% CI 1.282 to 4.745, p=0.006) in the Portuguese population was significantly associated with PCV and CFH rs800292 (OR 1.719; 95% CI 1.139 to 2.596, p=0.010) in the Singaporean population, respectively. CONCLUSION Among Asian and Caucasian patients with PCV, there are significant differences in the expression of phenotype. We also identified different polymorphisms associated with PCV in the two populations.
