Idiopathic juxtafoveolar retinal telangiectasia: a review and case report.

Idiopathic juxtafoveolar retinal telangiectasis is a group of retinal vascular anomalies characterized by retinal vessel dilation and tortuosity, multiple aneurysm formations, varying degrees of vascular leakage and lipid exudate deposition. Idiopathic juxtafoveolar retinal telangiectasis may occur as a primary disorder (either congenital or acquired), or may be caused or accompanied by other systemic or ocular diseases. The visual prognosis and effectiveness of therapy is dependent upon the etiology of the retinal telangiectasis. Included in this review is a case report, as well as the classification system used to identify idiopathic juxtafoveolar retinal telangiectasia.
