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.

AimsTo identify morphological characteristics preceding the development of exudative neovascularisation secondary to Macular Telangiectasia type 2 (MacTel) using multimodal retinal imaging.MethodsIn this retrospective study, eyes with a minimum observation period of 6 months prior to the de novo diagnosis of an exudative neovascularisation secondary to MacTel were analysed. Morphological changes preceding the formation of neovascularisation were evaluated using colour fundus photography, infrared imaging, fluorescein angiography, macular pigment measurement and optical coherence tomography (OCT). OCT-angiography (OCT-A) images were additionally available in a subset of patients.ResultsTwenty eyes from 20 patients were examined over a median period of 17 months (range: 6–100 months). Eyes were characterised by an accelerated progression of ellipsoid zone loss (median of 0.013 mm2/month), increased thickness of the temporal parafovea and hyper-reflective lesions on OCT. The latter underwent morphological changes preceding the development of exudative neovascularisation, including an increase in size and density, and expansion to outer retinal layers and the retinal pigment epithelium. All eyes showed a foveal depletion of macular pigment. On OCT-A, a focal increase in blood flow was observed at the level of the outer retina/choriocapillaris, and retinal–retinal and retinal–choroidal anastomoses preceded the formation of exudative neovascularisation.ConclusionsMultimodal imaging allows the identification of prognostic morphological features preceding the formation of exudative neovascularisation in MacTel. Eyes exhibiting these characteristics should be monitored closely and patients should be alert for emergent symptoms in order to detect and treat neovascularisation early and, thereby, prevent irreversible visual loss.
