Smoking and corneal biomechanics.
Dear Editor: Changes in the biomechanical properties of the human cornea play an important role in the pathogenesis of corneal dystrophies such as pellucid marginal corneal degeneration and keratoconus. The latter primarily affects young people and is a leading cause of severe visual impairment. Keratoconus is characterized by weakened corneal biomechanics that leads to progressive bulging and ...
متن کاملThe Relationship between Corneal Biomechanics and Corneal Shape in Normal Myopic Eyes
Introduction In a broad review, evidence that the corneal biomechanical properties influence the results and outcomes of various ocular measurements and procedures has existed for some time [1,2]. However, assessing the biomechanical properties of corneal tissue in vivo has previously not been possible. With the recent introduction of the Reichert Ocular Response Analyzer (ORA), direct clinical...
متن کاملPrimary Corneal Keloid
Purpose: To report the clinical presentation, histopathologic findings, and surgical treatment in a series of cases with primary corneal keloid. Case Reports: Six Iranian patients (a father and two sons, a mother and her daughter, and one isolated male patient) without any history of corneal trauma or systemic diseases were clinically and histologically evaluated for a slowly-growing, white opa...
متن کاملCorneal biomechanics - a review.
PURPOSE In recent years, the interest in corneal biomechanics has strongly increased. The material properties of the cornea determine its shape and therefore play an important role in corneal ectasia and related pathologies. This review addresses the molecular origin of biomechanical properties, models for their description, methods for their characterisation, techniques for their modification,...
متن کاملChanges in corneal curvature during accommodation in chicks.
Evidence is presented for an active corneal component of accommodation in chicks. Using anesthetized chicks, consistent increases in corneal curvature were observed during accommodation produced either by electrical stimulation of the Edinger-Westphal nucleus or by topical application of 0.4% nicotine sulfate to the cornea. Electrical stimulation produced a mean accommodative amplitude of 9.2 d...
