Dry eye, blinking, and blepharospasm.
The primary purpose of the eyelids is to ensure corneal integrity. An important component of this protective function is maintaining the corneal tear film. Blink characteristics can determine tear film stability. Increasing blink amplitude thickens the lipid layer that overlies the aqueous layer of the tear film. This thickening reduces evaporation of the aqueous layer. Because each blink refor...
متن کاملIncomplete blinking: exposure keratopathy, lid wiper epitheliopathy, dry eye, refractive surgery, and dry contact lenses.
Exposure keratopathy, including that which occurs following laser assisted keratomileusis, appears to be associated with incomplete blinking. Incomplete blinking may contribute to the signs and symptoms of lid wiper epitheliopathy. In addition, precipitation of contact lens surface deposits and other contact lens surface drying phenomena, appear to be accelerated by incomplete blinking. For the...
متن کاملSerial measurements of higher-order aberrations after blinking in patients with dry eye.
PURPOSE To study the sequential postblink changes in ocular higher-order aberrations (HOAs) in patients with dry eye. METHODS A wavefront sensor was used to measure HOAs sequentially for 30 seconds in 20 eyes of 20 patients with dry eye. The 20 eyes were classified into two groups, with or without superficial punctate keratopathy (SPK) in the central cornea. During the measurement, subjects w...
متن کاملEEG Eye-Blinking Artefacts Power Spectrum Analysis
Artefacts are noises introduced to the electroencephalogram’s (EEG) signal by not central nervous system (CNS) sources of electric fields inside and outside subject’s body. The artefacts impede the analysis of the signal and should be handled properly. The most common and characteristic kind of artefacts is the electrooculographic (EOG) ones, especially subject’s eye-blinking artefacts. In this...
متن کاملA Human Blinking ‘eye-on-a-chip’
This paper describes a human blinking eye-on-a-chip microdevice that reconstitutes the ocular surface in the human eye. To recapitulate the structural complexity of the ocular surface, we micro-patterned human cells derived from the cornea and conjunctiva on dome-shaped three-dimensional (3D) scaffolds in in vivo-like spatial arrangements. Moreover, this system was integrated with electromechan...
