Idiopathic Macular Telangiectasia

Idiopathic macular telangiectasia type 2 (IMT2) is a relatively uncommon clinical condition with an estimated prevalence of 1% within the general population. This condition can be challenging to precisely identify in early stages but advancements in clinical imaging to include fluorescein angiography and optical coherence tomography angiography (OCTA) can allow for timely diagnosis and prompt intervention that may leads to improved long-term clinical outcomes. Emerging literature has recognized the role of macular pigment (MP) in IMT2 in terms of Henle fiber layer deposition mechanisms and potential mitigation of inflammatory and oxidative stress. Primary care optometrists are in a unique position to facilitate early detection and manage through close evaluation and individualized lutein and zeaxanthin supplementation.

Purpose 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. Methods Three clinical cases of IMT2 are discussed. Clinical presentation, fundus photography, FA, SD-OCT, and OCTA are presented. Each case illustrates variable presentation, staging, and associated findings related to IMT2. Results Optical coherence tomography angiography provides additional value when paired with traditional multimodal imaging in the assessment and management of IMT2. Conclusions These cases present an opportunity to demonstrate the features of the OCTA in the evaluation of vascular diseases such as IMT2. Additionally, these examples emphasize the critical importance of OCTA in the clinical diagnosis and management of IMT2.

Optical coherence tomography angiography (OCTA) is a recently established noninvasive technology for evaluation of the retinal and choroidal vasculature. The literature regarding the findings in macular telangiectasia type 2 (MacTel2) is scarce. We report the OCTA findings associated with a subject with MacTel2 and secondary subretinal neovascularization (SNV). The commercially available Cirrus 5000 with AngioPlex (Zeiss, Jena, Germany) was used, without any subsequent image modification or processing. Subretinal neovascularization was detectable with OCTA at the level of the outer retina and choriocapillaris. Microvascular abnormalities associated with MacTel2 were present mostly in the deep capillary plexus of the retina temporally.
