Sclerotic = relating to sclerosis or to the sclera
Sclerosis = "a pathological hardening of tissue especially from overgrowth of fibrous tissue or increase in interstitial tissue" (thank you to Merriam Webster online dictionary - http://www.merriam-webster.com/dictionary/sclerosis)
Sclera (also known as sclerotica ... yes, it's really true) = "the dense fibrous opaque white outer coat enclosing the eyeball except the part covered by the cornea" (Merriam Webster again - http://www.merriam-webster.com/dictionary/sclera)
