Ultra-widefield imaging in Coats'-type retinitis pigmentosa

Fundus revealed arteriolar attenuation and diffuse bone-spicule pigmentation involving the macula [Figure 1]a and [Figure 1]b. Vascular telangiectasia and lipid exudation were present in temporal and inferior retina in OU. Ultra-widefield (UWF) fluorescein angiography [Figure 2]a and [Figure 2]b showed patchy hypo- and hyperfluorescence corresponding to bone-spicule pigmentation, retinal sparing along the vascular arcades (especially left eye [OS]), and multiple bulb-like dilatations of vessels in inferotemporal quadrants [Figure 2]a and [Figure 2]c. Inferiorly steered picture in OD [Figure 2]b and temporally steered picture in OS [Figure 2]d showed leakage from neovascularization in late phases. UWF imaging may reveal peripheral findings in addition (retinal neovascularization in this case) which may help in better documentation and characterization of the disease process.
