Unveiling idiopathic macular telangiectasia: clinical applications of optical coherence tomography angiography
Idiopathic macular telangiectasia type 2 (IMT2) is a bilateral acquired maculopathy, with a spectrum of clinical presentations associated with inner retinal telangiectatic vascular anomalies. Cases often are underdiagnosed or misdiagnosed. Current diagnostic modalities such as spectral-domain optical coherence tomography (SD-OCT) and fluorescein angiography (FA) are valuable to the understanding of the clinicopathology. More recently, optical coherence tomography angiography (OCTA), as an emerging noninvasive technology, has been shown to be particularly useful in the assessment and management of IMT2. Three clinical cases of IMT2 are discussed. Clinical presentation, fundus photography, FA, SD-OCT, and OCTA are presented. Each case illustrates variable presentation ...
