Abstract: Intraocular pressure measurement devices and techniques for use therewith are generally described. In some examples the pressure measurement device may include a sleeve comprising a lower end including a first opening and an upper end. In various examples, a fastener may be used to secure the upper end of the sleeve to a device comprising an image sensor. In some examples the intraocular pressure measurement devices may comprise an applanator having an optically clear body, a first end effective to protrude from the first opening of the sleeve, and a tip at the first end. In some examples, the applanator may be slidably retained within the sleeve such that when the sleeve is positioned vertically above an eye of a subject, the applanator may slide downward until the tip of the applanator protrudes from the first opening of the sleeve and rests upon a surface of the eye.
