Figure 1:(a) Fundus photograph of the left eye shows dilated and tortuous retinal vessels, 0.6:1 cup disc ratio and thin superior and inferior neuroretinal rim (NRR). (b) Fundus photo of the left eye shows a decrease in the major retinal vessels tortuosity. Optic disc shows diffuse pallor, 0.4: 1 CDR, coiled collateral vessels on the supero-nasal neuroretinal rim (white arrow), fine collaterals (blue arrow), and tuft of capillaries on the border of temporal NRR
