Current imaging advancements have led to emergence of pachychoroid as an association of important vision threatening diseases like chronic serous chorioretinopathy and polypoidal choroidal vasculopathy. While the precise relation between thick choroid and such disorder is being investigated, the etiology behind pachychoroid remains elusive. We hypothesize pachychoroid to be a resultant of impeded vascular outflow due to thick sclera and increased scleral rigidity. We discuss our hypothesis in the perspective of other choroidal manifestations of anomalously thick scleral structure.
目前的成像技术进展使得后葡萄膜增厚成为一系列重要的威胁视力疾病的一个关联，如慢性浆液性脉络膜视网膜病变和息肉样脉络膜血管病变。虽然厚脉络膜与这些疾病的确切关系仍在研究中，但后葡萄膜增厚的病因仍不清楚。我们假设后葡萄膜增厚是由于巩膜增厚和巩膜刚性增加导致的血管流出受阻的结果。我们从异常厚巩膜结构的其他脉络膜表现的角度来讨论我们的假设。
