Purpose: Angioid streaks (AS) are dehiscences in Bruch's membrane that may be idiopathic or associated with numerous systemic illnesses. Polypoidal choroidal vasculopathy (PCV) is an underdiagnosed exudative chorioretinopathy often characterised by serosanguineous detachments of the pigmented epithelium. The use of the anti-VEGF agents ranibizumab and aflibercept in the management of PCV secondary to AS has not been previously documented. We report 3 patients with active PCV secondary to AS, 1 of which had a family history of PCV secondary to AS, not previously reported in the literature. All patients were symptomatic and treated with intravitreal anti-VEGF therapy with and without combination photodynamic therapy (PDT).
Methods: This is a long-term retrospective case review of 3 eyes of 3 patients with AS and clinical features of PCV. The patients were examined using fundoscopy, spectral domain optical coherence tomography, fluorescein angiography, and indocyanine green angiography. All patients were managed with intravitreal anti-VEGF using a treat-and-extend protocol according to specific retreatment criteria. One patient had 1 session of PDT in combination with anti-VEGF injections.
Results: The mean follow-up time in all patients was 4 years. In all 3 cases, the treatment resulted in improved visual acuity and regression of active PCV lesions with a longer duration between injections.
Conclusion: The treat-and-extend protocol with intravitreal aflibercept or ranibizumab with or without PDT is effective and safe for PCV secondary to AS.

Background: After pneumococcal disease and colonization have been controlled through vaccination campaigns, a reduced pneumococcal conjugate vaccine (PCV) schedule may be sufficient to sustain that control at reduced costs.
Methods: We investigated whether a single primary dose and booster dose (1p+1) of the 10-valent PCV (PCV10) would be noninferior to alternative dose schedules in sustaining control of carriage of pneumococcal serotypes included in the vaccine. In Nha Trang, Vietnam, an area in which PCV had not been used previously, a PCV10 catch-up campaign was conducted in which the vaccine was offered to children younger than 3 years of age, after which a cluster-randomized trial was conducted in which children received PCV10 at 2, 3, and 4 months of age (3p+0 group); at 2, 4, and 12 months of age (2p+1 group); at 2 and 12 months of age (1p+1 group); or at 12 months of age (0p+1 group).

Aim: To investigate the patterns of short-term intraocular pressure (IOP) fluctuations and identify the contributing factors following intravitreal injection in patients with retinal vascular diseases.
Methods: Totally 81 patients were enrolled in this case control study. Eyes were categorized into 7 groups, including age-related macular degeneration (AMD), polypoidal choroidal vasculopathy (PCV), idiopathic choroidal neovascularization (CNV), proliferative diabetic retinopathy (PDR), diabetic macular edema (DME), macular edema secondary to branch (BVOME) and central (CVOME) retinal vein occlusion.

Purpose: To determine the efficacy and safety of proton beam irradiation (PBI) and anti-vascular endothelial growth factor (anti-VEGF) therapy for polypoidal choroidal vasculopathy (PCV)/ aneurysmal type 1 macular neovascularization (AT1).
Methods: The randomized clinical trial consisted of newly diagnosed active PCV/AT1 patients who were randomized 1:1 to treatment with three initial monthly intravitreal anti-VEGF agent (conbercept) injections with or without single 14 GyE radiation. Subsequent anti-VEGF therapy was given pro re nata.
