Illustrative case of LHON patient with central scotoma. (a) VF results of both eyes (right eye on the right and left eye on the left) obtained with semiautomated kinetic perimetry and V4e stimulus moved with the speed of 5 degrees per second in patient with LHON. Visual acuity was counting fingers to 2 meters in both eyes. Central scotoma and peripheral residual VF measured in square degrees (deg2). (b) VF results of both eyes (right eye on the right and left eye on the left) obtained with static automated perimetry in patient number with LHON. (c) Fundus pictures (right eye on the left and left eye on the right) of patient number 8 showing swelling of the retinal nerve fibers involving the superior and inferior arcades around the optic disk, as well as retinal vessel tortuosity.
