ABSTRACT
Keratoconus is a corneal ectatic disease characterized by progressive corneal thinning and protrusion. Its pathogenesis remains unclear. In vitro experiments have shown that mechanical stimulation may damage corneal stromal cells by increasing oxidative stress level and inflammatory factor concentration, resulting in a series of changes such as degradation of corneal extracellular matrix. Numerous clinical studies have confirmed that mechanical factors, including eye rubbing and eyeball compression caused by sleeping position, may play an important role in the process of keratoconus occurrence and development. They may affect the cornea by increasing the level of inflammatory factors in tear, causing changes in intraocular pressure, changing the biomechanical properties of the cornea, directly damaging corneal tissue by mechanical friction, and increasing the temperature of corneal epithelium. The main aim of this review was to describe the efforts of mechanical factors on corneal stromal cells, corneal tissue, and the possible role of mechanical factors in the pathogenesis of keratoconus, so as to provide a reference for the prevention and management of keratoconus.
