A detailed investigation into the cation and immunoglobulin content of tears from glaucoma, allergy and normal patients is the subject of this paper. I first became interested in detecting possible differences in cation levels of glaucoma and normal tears, during my sophomore Career and Service Quarter. At this time I observed an elevated sodium content in the tears of glaucoma patients, although the potassium content remained normal. I also ran tandem investigations into the sodium and potassium levels of the blood serum from these same glaucoma and normal patients. I found the serum sodium and potassium average levels to be identical in both patient groups, and consequently I eliminated the investigation of serum contents from this present study. After reviewing an immunoglobulin study done on tears, serum, and saliva I decided to include an immunoglobulin investigation it my tear studies.
