The thickening line is an acidic marking of heightened congestion, and holds negative tendencies. A line should always be thicker at the base, and not at the tip as it nears the iris. In this sclera image this sign can be seen in the kidney area, ending in the ureter. It passes through the adrenals (which sit atop the kidneys), indicating a degree of adrenal fatigue and congestion. We would suspect that this person may suffer kidney pain at times, with susceptibilities to bladder infections and irregular micturition. Associated with this sign are parasite and worm pockets, usually present in negative tissue environmental conditions, alongside markings indicating a neoplastic nature.
