“…All of these rigidity-affecting components increase the force on the tonometer prism, which is erroneously attributed to intraocular pressure despite having no direct relation to IOP. Finally, the hydrostatic attraction created by the tear film was theorized to negate much of the rigidity error, but tear films are also highly variable among patients [13][14][15]. Intraocular pressure, with all presently utilized clinical methods of tonometry, is thus just an approximation of IOP with associated inter-patient biases due to biomechanical variability.…”

An increased awareness of how central corneal thickness (CCT) and corneal material properties such as corneal hysteresis has changed both tonometry accuracy and the resultant understanding of glaucoma risk. New research findings and methods of tonometry provide differing information on the diagnosis and treatment of ocular conditions which should be understood to appropriately incorporate this information into individual patient care. Additionally, a useful re-examination of what IOP can tell us about glaucoma empowers practitioners to improve glaucoma outcomes. All clinically utilized tonometry methods are estimates of true IOP, which is only assessed using direct intracameral techniques. Different described tonometry techniques are associated with their own overall bias and interpatient variability, due most typically to tissue biomechanics.

Hydrophobicity effect in the self assembly of particles in an evaporating droplet

The prevailing exposition of the particle deposition mechanism in an evaporating droplet for self-assembly does not lead one to expect any deviation in deposition behavior to occur when two different particle types (of differing hydrophobicity) are used while keeping all other key parameters (i.e., particle concentration, particle size, and liquid volume) comparable. It is well known that if the contact angle that the droplet makes with the surface is sufficiently low a “coffee stain” pattern results, and that if the angle is sufficiently high few deposits are left behind except a dot at the center of the dried out droplet. We explore the behavior in the large intermediary region, and find that it depends strongly on particle properties. Droplet evaporation experiments conducted with micron sized polystyrene and silica particles on glass coated with silane suggest that the basic deposition mechanism outlined can be strongly influenced by a balance between capillary forces and the drag arising from flow patterns in the droplet, and interparticle capillary force factors.
