crystalline

Like a crystal. It refers to a uniform atomic structure throughout the entire material. For example, the silicon in most integrated circuits is crystalline (see crystalline silicon). In phase change optical discs, the spots (bits) on the recording layer that are crystalline allow a greater reflection of the laser beam than do the amorphous spots, which have a random atomic structure. Contrast with amorphous. See liquid crystal, phase change disc and phase change memory.


Crystalline vs. Amorphous
This magnified UDO disc from Plasmon shows the less reflective amorphous (grey) and more reflective crystalline (light/dark) bits. The crystalline area is not a single crystal, but a multi-crystalline region. Due to different crystal alignments and interaction of the beam used to image the material, the reflective bits appear variously light and dark. The different sizes of bits are due to UDO's encoding method. (Image courtesy of Plasmon, www.plasmon.com)

Thus, the purpose of this study was to determine the relationship between the retinal morphology and the crystalline deposits. To accomplish this, we studied three patients with BCD by high-resolution imaging including SD-OCT and AO retinal imaging.
All of the crystalline deposits detected in the fundus photographs were also detected in the infrared images in all patients as reported (Figure 1) [11,12,32].
reported that the crystalline deposits observed in patients with BCD were mainly located on the inner side of the RPE layer [12].
The patient was diagnosed with nephropathic cystinosis based on these findings and the presence of ocular crystalline deposits. Following cysteamine treatment, clearance and phosphorus levels returned to normal in the follow-up 24-hr urinalysis.
(8) While these crystalline deposits often do not cause visual impairment, in rare cases they may form band keratopathy, thus affecting the central cornea and reducing visual acuity.
In our patient, the hyperreflective areas detected on OCT did not correspond directly to the retinal crystalline deposits, whereas Ayata et al.
Interestingly, it is now thought that crystalline deposits in joints may be responsible for many cases of arthritis.
