a, b Color fundus photographs of left and right eye showing multiple glistening small yellow crystals scattered intravascularly and extravascularly within the posterior pole. c, d Adaptive optics images of the two yellow squares marked in the color fundus photographs in a, b. Arrows point the clumps of talc particles seen in the color fundus photographs. Arrow heads point the tiny talc particles that could not be detected clinically. (1), (2) OCT scans corresponding to the 2 green lines in the color fundus photographs demonstrating the location of these talc crystals (hyper-reflective dots).

Fig1
Crystals appeared to be located inside small retinal arterioles and venules of the macula with few crystals scattered outside the vessels within the retina (Fig. 1). The high resolution of AO allowed detection of some tiny particles that were not detectable clinically (Arrow heads: Fig. 1).  
OCT scans through different areas of the retina showing the location of talc crystals in different retinal layers: Nerve fiber layer (1), Ganglion cell layer (2), inner plexiform layer (3) and inner nuclear layer (4). The second OCT scan (2) demonstrates thinning of the inner retinal layers.

Fig2
SD-OCT demonstrated multiple hyper-reflective dots of varying sizes scattered among the nerve fiber layer, ganglion cell layer, inner plexiform and inner nuclear layer (Fig. 2). Thinning of the inner retinal layers in temporal part of the macula, a finding similar to that usually seen with vascular occlusion was also noted in the right eye (Fig. 2).
