This marking is such an excellent example of a blood pressure loop, or a ‘Squiggle’ line. It is topolabile sign, meaning it is not relevant to its location in the sclera, and is systemic. The blood pressure loop presents exactly as it is named – as a loop along a line, sometimes looping multiple times. It is an indication of a blood pressure abnormality, signalling either high or low blood pressure in a person. Further questioning of signs and symptoms, as well as examination of additional associated sclera markings would be used to identify whether the blood pressure loop indicated either high blood pressure, or low blood pressure in the client.

Also noted in this client is the drying up of the synovial fluid, or gel, within the sclera, indicating a possible vitamin A deficiency.
