Thygeson’s Superficial Punctate Keratitis Laboratory Studies
The truth is that Laboratory Studies regarding the cause of Thygeson’s Superficial Punctate Keratitis (TSPK) have failed to determine the cause or causes of this disease. It is reported that medical personnel can try culturing the flora when there is active inflammation of the cornea, but it will not affect the management, diagnosis, or treatment of TSPK.
Medical research has determined that this disease is either going to be found in an inactive or active state. A traditional lesion in the cornea when TSPK is active will be round, rough, raised, and have gray-white dots. Each time the TSPK is active there may only one lesion or even 50 lesions with physicians noting that the average is about 20 lesions. During the active stage of TSPK the cornea will remain sensitive.
Inactive stage of Thygeson’s Superficial Punctate Keratitis, Thygeson’s Superficial Punctate Keratopathy, or TSPK in patients has shown that all lesions can vanish. The lesions may stick around during the inactive stage and will be stellate formed, dull gray, subepithelial opacities that a Fluorescein application will not stain. This condition can be permanent even when overlying epithelial disease is not present in the patient.
The disease is different is some ways because all people are unique and there are many factors that may affect how the affliction works. Some TSPK attacks can go into remission for three years and return. Some people will only suffer for a matter of months. The average length of time that the disease is active runs about 3.5-7.6 years. The toughest reported cases show that the disease has been part of some people’s lives for 25, 30, or more than 40 years. This is why there is so much emphasis on Thygeson’s Superficial Punctate Keratitis laboratory studies that may eventually help the unknown number of people that have to deal with the symptoms.
