OBJECTIVE To assess the reliability and accuracy of smartphones in diagnosing transmitted fundus images in comparison with a laptop. MATERIALS AND METHODS Fundus images captured with a Topcon NW 200 camera were transferred onto a conventional laptop and a smartphone and given to ophthalmologists for diagnosis. The smartphone and the laptop diagnosis were(More)
In the mol-ecule of the title compound, C(20)H(16)N(6), the central C-C bond lies on a crystallographic inversion centre. The quinoxalidine ring is nearly planar, with a maximum deviation of 0.021 (2) Å from the mean plane. The crystal structure is stabilized by inter-molecular C-H⋯N inter-actions, leading to the formation of a layer-like structure, which(More)
In the title mol-ecule, C(16)H(11)N(5), the mean planes of the quinoxaline and indazole fragments form a dihedral angle of 10.62 (5)°. In the crystal, weak inter-molecular N-H⋯N hydrogen bonds link the mol-ecules into zigzag chains extending in the [001] direction. The crystal packing also exhibits π-π inter-actions [centroid-centroid distances of 3.7080(More)
