one,2 Any circumstances that have an affect on the formation of aqueous humor or outflow of aqueous humor bring about modifications in IOP. Community and systemic disorders, medicines, and ocular surgeries have an affect on IOP. Larger IOP amounts are connected to ganglion mobile and nerve fiber layer loss.

However, the more recent procedures do present added clinical information that early experiments have demonstrated do incorporate diagnostic understanding, for instance, ocular pulse amplitude of your DCT and corneal biomechanical Houses in the ORA.
In order that your tonometer is often furnishing correct readings, It's also crucial that you Keep to the producer's Directions for use and routine maintenance.
