| Abstract | ||||
| Background: Myopia is a common pathologic change in the eye and almost unavoidable. Myopic changes in the eyes include extended axial length, deeper anterior chamber and glass depth, a thinner retina and a higher retinal detachment prevalence, lower choroid circulation as well as lower sclera and elasticity. Corneal densitometry reflects corneal clarity as well as health. The internal structure of the cornea reduces the scattering of light to a minimum. Increased corneal light dispersal in different corneal disorders has been reported. Objective: Evaluate corneal densitometry values obtained using Scheimpflug tomography in different grades of myopic eyes for patients attending to Mansoura University Ophthalmic Center. Patients and methods: This cross-sectional study included 45 Myopic patients who were recruited over one year from November 2019 to October 2020. Patients were classified into three grades; low myopia, moderate myopia and high myopia. All cases had history and complete ophthalmic examination including visual acuity assessment, autorefractometer testing and slit lamp examination. The Pentacam Scheimpflug imaging system was used to examine myopic cornea. Results: There was a statistically significant difference in the corneal densitometry in the (6-10 mm) zone in all in the total, anterior, central and posterior corneal layers. There was no statistically significant difference between the different grades of myopia regarding the corneal densitometry of the other different zones of the corneal regions. Conclusion: Assessment of corneal densitometry by pentacam could be used as a method of assessment of corneal clarity between different cases with myopia. | ||||
