Central retinal artery occlusion secondary to presumed traumatic carotid artery dissection in a healthy child.

PURPOSE: To describe a rare case of a 13 years-old healthy child that presented CRAO secondary to carotid artery dissection, which occurred after a neck rotation movement. METHODS: Case report with prospective literature review. PATIENTS: One patient described in the case report. RESULTS: Not applicable. DISCUSSION/CONCLUSION: Internal carotid artery dissection is a rare condition, specially in children, that can lead to serious cerebral-ocular ischemic events. It may occur due to direct vessel trauma or spontaneously. Prompt imaging screening is of paramount importance because early antithrombotic treatment or surgical intervention may significantly reduce the incidence of devastating ischemic events, such as stroke or central retinal artery occlusion.

Pachychoroid disease spectrum: review article.

PURPOSE: The aim of this article is to do a comprehensive literature review about the current understandings of the pachychoroid disease spectrum, describing its multimodal imaging analysis, pathophysiology, differential diagnosis, and current types of management. METHODS: This comprehensive literature review was performed based on a search on the PubMed database, of relevant pachychoroid published papers according to our current knowledge. DISCUSSION: The pachychoroid disease spectrum, according to some authors, includes the following: pachychoroid pigment epitheliopathy (PPE), central serous chorioretinopathy (CSC), pachychoroid neovasculopathy (PNV), polypoidal choroidal vasculopathy (PCV)/aneurysmal type 1 neovascularization (AT1), and more recently focal choroidal excavation (FCE) and peripapillary pachychoroid syndrome (PPS). Each one of these entities will be described and discussed in this article. CONCLUSION: Significant advances in multimodal imaging have enabled a better understanding of the typical choroidal changes in pachychoroid disease spectrum. The clinical knowledge and managing options about this disease significantly increased in the last years. However, it is still unclear why some eyes with typical pachychoroid disease phenotype show no evidence of RPE damage and subretinal fluid (uncomplicated pachychoroid) while others present progressive tissue damage, neovascularization, and atrophy.
