Pentacam Topography and Macular Optical Coherence Tomography Findings In Eyes Presenting With Refractive And Axial Myopia

Background: Myopia is circular refractive error in which parallel light rays enter eye and shift point of conjugate focus anteriorly in front of retina. High myopia is usually with (>−6.00 SD) or axial length (AL) more than 26 mm. Aim and objectives: Goal of research is to identify the results in eyes presenting with refractive and axial myopia using macular optical coherence tomography & pentacam. Subjects & techniques: research is prospective research that will be carried out on 60 eyes with high myopia more than or equal -6SD. Ages ranging from 20 to 70 years old. They will be divided into two groups A- refractive myopia B- axial myopia and meeting the inclusion criteria. Results: There was non-important variation among 2 tested groups concerning anterior segment parameters (CCT, ACD, & WTW). A negative relation between axial length & CMT. While, there was positive relationship among axial length, age & WTW. No relationship was shown among axial length & ACD. There was highly statistically significant RPE thinning were found in axial myopia, While, CNV, RD and MH was with on statistical significance. Conclusion: Assessing anterior and posterior segment is essential for patients with high myopia to detect various types of diseases or before planning for refractive surgeries, & for prescribing & exactly measuring power of contact lenses & IOLs.
