How would you manage this small melanocytic choroidal tumour?

CASE REPORT A 68-year-old lady was referred to the Jules-Gonin Eye Hospital (Lausanne, Switzerland), 6 months after her ophthalmologist had observed, during routine eye examination, an asymptomatic, parapapillary, choroidal pigmented tumour in the left eye, covered with drusen and without any orange pigment or associated serous retinal detachment (figure 1A). Best corrected Snellen visual acuity was 0.7 in the right eye, related to a relative hypermetropic amblyopia known since childhood, and 1.0 in the left eye. On fluorescein angiography, pigment epithelial alterations were present, with limited diffusion of the dye (figure 1B).
