Abstract

Purpose

Idiopathic macular telangiectasia (MacTel) is classified into aneurysmal telangiectasia (type 1), perifoveal telangiectasia (type 2) and occlusive telangiectasia (type 3). Most instances of telangiectasia in Western countries are type 2. This study reports clinical and demographic features of MacTel in Japanese patients.

Methods

Newly diagnosed patients with MacTel were examined retrospectively. All patients underwent fluorescein angiography and optical coherence tomography.

Results

Thirty-four eyes of 27 patients with MacTel were included. Twenty eyes of 20 patients (74.1%) had type 1, ten eyes of five patients (18.5%) had type 2, and four eyes of two patients (7.4%) had type 3. Foveal capillary dilatation and microaneurysms were observed in all except for one eye of early stage type 2 MacTel. Optical coherence tomography revealed cystoid macular edema in type 1, temporal foveal thinning and a loss of boundary between the inner and outer segments of photoreceptors in type 2, and thinning of all retinal layers around the fovea in type 3.

Conclusion

The most frequent among our patients was aneurysmal MacTel, whereas perifoveal MacTel was not common. Although the clinical characteristics were similar, the most common type was different from that in Western countries.
