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.
