Systemic effects of anti-VEGF intravitreal injection in patients with age-related macular degeneration: A multi-institutional real-world study.

Purpose: In individuals aged >50 years, age-related macular degeneration (AMD) is the leading cause of irreversible blindness. Intravitreal injections of antivascular endothelial growth factor (VEGF) agents (bevacizumab, ranibizumab, and aflibercept) show good efficacy and similar incidences of systemic adverse events (SAEs). However, comparative studies between agents are limited.

Systemic Outcomes of Intravitreal Injections of Dexamethasone and Anti-Vascular Endothelial Growth Factor.

Introduction: Intravitreal dexamethasone and anti-vascular endothelial growth factor (anti-VEGF) medications have revolutionized ocular disease management and favorable ocular safety profiles, but few studies have compared their systemic adverse events (SAEs). This study investigated the SAEs of intravitreal dexamethasone and anti-VEGFs by using real-world data.

Methods: This retrospective cohort study sourced medical records from the largest multi-institutional database in Taiwan.

Characterisation of macular neovascularisation subtypes in age-related macular degeneration to optimise treatment outcomes.

The aim of this review is to identify the common characteristics and prognoses of different subtypes of neovascular age-related macular degeneration (nAMD). We also propose recommendations on how to tailor treatments to the subtype of neovessels to optimise patient outcomes. The authors, selected members of the Vision Academy, met to discuss treatment outcomes in nAMD according to macular neovascularisation (MNV) subtypes, using evidence from a literature search conducted on the PubMed database (cut-off date: March 2019).

Retinal vasoproliferative tumor regression after intravitreal aflibercept.

Retinal vasoproliferative tumors (RVPTs) are rare benign retinal lesions typically located in the inferotemporal peripheral retina. Several treatment options exist for the management of RVPTs, but no consensus has been proposed. There are only a few reports on the use of anti-vascular endothelial growth factor with bevacizumab to treat exudative or neovascular retinal changes secondary to RVPTs.

Optimal approaches and criteria to treat-and-extend regimen implementation for Neovascular age-related macular degeneration: experts consensus in Taiwan.

The management of neovascular age-related macular degeneration (nAMD) has taken a major stride forward with the advent of anti-VEGF agents. The treat-and-extend (T&E) approach is a refined management strategy, tailoring to the individual patient's disease course and treatment outcome. To provide guidance to implementing anti-VEGF T&E regimens for nAMD in resource-limited health care systems, an advisory board was held to discuss and generate expert consensus, based on local and international guidelines, current evidence, as well as local experience and reimbursement policies.

Management of neovascular age-related macular degeneration: Taiwan expert consensus.

Neovascular age-related macular degeneration (nAMD) is a leading cause of irreversible vision loss. The present consensus provides suggestions on diagnosis, evaluation, treatment, and follow-up strategies for nAMD from a panel of 11 practicing ophthalmologists. The experts suggest that the baseline visit for nAMD management should include a comprehensive ophthalmologic examination via a multimodal approach consisting of visual and anatomical evaluation.

Management of diabetic macular edema: experts' consensus in Taiwan.

Diabetic macular edema (DME) is the most common cause of vision loss among patients with diabetes mellitus (DM), rendering it an important growing challenge in ophthalmology. In the past decades, the management strategies for DME had a few paradigm shifts, and the advent of an expanding number of anti-vascular endothelial growth factor (VEGF) agents also calls for an in-depth examination of the currently available evidence. This article was composed with the intention to provide recommendations for practicing clinicians to improve the management and, through it the outcomes of DME.

Clinical ocular manifestations of Taiwanese patients with mucopolysaccharidoses VI (Maroteaux-Lamy syndrome).

Mucopolysaccharidoses (MPS) is a group of lysosomal storage disorders that lead to accumulation of glycosaminoglycans (GAGs) in many tissues and organs, resulting in different clinical features. In this study, we conducted the manifestation changes of refractive error, corneal clouding, and intraocular pressure in two Taiwanese MPS VI patients with enzyme replacement therapy (ERT) initiated at the age of eight. In case 1, hyperopia was noted before and after ERT.

Management of polypoidal choroidal vasculopathy: Experts consensus in Taiwan.

Polypoidal choroidal vasculopathy (PCV) is a prevalent retinal disease predominantly occurs in Asians that shares some similarities seen in neovascular age-related macular degeneration. Recent large multicenter clinical trials on intravitreal anti-vascular endothelial growth factor (VEGF) agents and photodynamic therapy (PDT) have shed lights on the management of PCV. The Taiwan National Health Insurance had granted limited anti-VEGF agents and PDT for patients with PCV after the approval of required data submission, especially fundus angiography, optical coherence tomography, and visual acuity.

Ophthalmologic manifestations in Taiwanese patients with mucopolysaccharidoses.

Background: Mucopolysaccharidoses (MPSs) are a group of rare lysosomal storage disorders characterized by the accumulation of glycosaminoglycans in various tissues and organs. Ocular problems that affect the cornea, trabecular meshwork, sclera, retina, and optic nerve are very common in these patients. However, there was limited literature focusing on comprehensive ocular findings in different types of MPS.
