Abstract :
The intraocular pressure has been a subject of considerable speculation since it is the only modifiable risk factor for Primary Open Angle patients.
This fluctuation follows a reproducible pattern in most of the eyes. However, there are some eyes which do not follow a consistent pattern of this fluctuation. The need to precisely measure this pattern stems from the fact that a single office based measurement could miss these pressure peaks.
Recording the diurnal variation proves to be an effective tool in management of progression of Primary Open Angle Glaucoma as it not only identifies the time of the day when the pressure peaks to enable us to tailor the therapy to appropriately timing the drug administration but it also offers an understanding of range of intraocular pressure fluctuation during the day.
