Özet

Aim: To investigate changes in retinal and choroidal vessels in children with primary and secondary

raynaud’s phenomena(RP).

Methods: Measurements were performed by optic coherence tomography angiography before as well as

during and 10 minutes after the immersion of one hand in ice water.

Results: Primary RP patients exhibited enlargement of the foveal avascular region and decrease in vessel

density in the parafoveal superficial capillary plexus (SCP) during cold exposure, but values returned to

normal when the hands were removed from the cold water. In children with secondary RP, there were

decreases in choroidal thickness and vessel density in the SCP and radial peripapillary capillary plexus

(RPCP) during cold exposure. Changes in choroid and peripapillary RPCP were still significant 10 minutes

after removal from cold water.

Conclusion: Ocular arteriolar vasospasm seems to be more pronounced in patients with secondary RP,

particularly in the choroid and the peripapillary area of the RPCP.
