ABSTRACT
The study aimed to introduce a new analysis method of 24-hour intraocular pressure (IOP) and to propose the concept of overall IOP. Data of 24-hour IOP of a patient with a confirmed diagnosis of normal tension glaucoma was selected. Based on the present indexes including peak IOP, trough IOP, maximum difference, and mean IOP, new indexes were proposed, which included main IOP, duration of main IOP, and rate of IOP increase. A radar chart was drawn, and overall IOP was calculated. Overall IOP value = IOP distribution (sum of IOP value multiplied by the corresponding duration) × IOP fluctuation (standard deviation) × rate of IOP increase/100. By comparing two series of IOP data, the advantages of the new IOP indexes were demonstrated. The introduction of the concept of overall IOP expands the description of IOP from a single static state to a comprehensive dynamic state, which enables us to analyze the results of 24-hour IOP monitoring more thoroughly.
