Retinal nerve fibre layer thickness and choroidal thickness: An evaluation in psoriasis patients.

The increase in choroidal thickness was found to be significant, while with respect to RNFL thickness, a decrease was evident, a possible indicator of damage to microvascular structures in the choroid and ganglion cells, especially in patients with severe psoriasis. Therefore, choroidal and RSLT thickness measurement with OCT device can assist in the detection of damage to psoriasis.
