Purpose: Ocular ischemic syndrome can be the first and only hint of life-threatening carotid artery disease. The early recognition of carotid stenosis-related retinal signs, as well as the comprehension of the pathophysiology behind retinal changes could become relevant for physicians to predict the risk of stroke. The aim of this study is to assess the carotid artery disease-induced early structural retinochoroidal changes by means of swept-source optical coherence tomography (SS-OCT).

Purpose: To report 12-year follow-up of a patient with ARB.
Case Report: A 25-year-old man presented with blurred vision in his both eyes (OU). Best-corrected visual acuity (BCVA) was 20/63 Snellen equivalent in the right eye (OD) and 20/32 Snellen equivalent in the left eye.
Significance: Cone dystrophies and cone-rod dystrophies are a group of rare inherited pathologies characterized by degeneration of cone photoreceptors and subsequent rod involvement. The identification of causative genes is essential for diagnosis, and advanced imaging is acquiring great value in the characterization of the different phenotypic expressions.
Purpose: We describe genotype-phenotype associations of an autosomal recessive ABCA4-associated cone dystrophy using multimodal imaging.
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.
Significance: The emergence of new cancer therapies has dramatically improved outcomes in metastatic melanoma. Immune checkpoint inhibitors have been the most effective treatment. Although, as a direct consequence of the immune dysregulation induced by them, adverse effects termed immune-related adverse events are observed in more than 60% of the patients.

As the pandemic is spreading and the whole picture is yet unknown, ophthalmologists should be aware of unusual ocular presentations of COVID-19 since they could precede the development of severe respiratory distress.
Methods: We report here the first case of a patient with bilateral unusual dot-blot retinal hemorrhages and retinal venous dilation who presented shortly thereafter a PCR-proven COVID-19.

Purpose: The term "pachychoroid" refers to a newly described phenotype in which functional and structural choroidal changes are thought to play a key pathogenic role in a spectrum of related retinal disorders. A more detailed understanding of how the choroid is involved within this spectrum and a better knowledge of the most relevant clinical signs of the pachychoroid phenotype are important to differentiate these disorders from other retinal conditions. Our objectives are to provide a literature review of pachychoroid and the commonalities that may be present across pathologies included in the spectrum, and to provide details on the examination, monitoring, and management of these disorders.
