Kibblewhite, who uses a guide dog and has been registered blind since 2015, had been offending since 2011 and the court heard he took extraordinary action to continue with his crimes as his sight failed.
“While the number of images you possessed were, in comparative terms, not great, the images were amongst the most vile that these courts come across and the offences were committed over a 10 year period,” Sheriff John Speir said to Kibblewhite.
“Halfway through your sight difficulties became worse and it is a matter of some concern that you took steps to overcome these difficulties by relying on others via communication apps such as Skype to narrate what was being displayed for your sexual gratification.
“You went to considerable effort to contact others so your criminal behaviour could continue and you have no insight on the impact this would have had on the victims of child sexual abuse.”
