Objective: We aimed to investigate the effects of myopia and hyperopia on the optic disc analysis parameters and to compare results cases with emmetropia by using Heidelberg Retinal Tomography (HRT).
Material and Methods: In this study, we included 35 myopic, 35 hyperopic and 35 emmetropic of healthy Turkish population, which comprised 210 eyes of 105 cases. HRT parameters were compared between these 3 groups.
Results: We found that in myopic group disc area, rim area and rim volume values are significantly higher than that of the other two groups. We concluded that disc size is correlated with axial lenght increment. Maximum cup depth values were found higher in emmetrops than myopics, and in myopics than hyperopics. Cup volume, height variation contour, mean Retinal Nerve Fiber Layer (RNFL) thickness and reference height values were found higher in emmetropics than myopics and hyperopics in left eyes. No significant changes were found when correlated with sex and laterality.
Conclusion: As a result, our findings supported the importance at refraction errors in the diagnosis and follow up of glaucoma and optic disc disorders. If we know the effects of refraction error in all these measurements, we think that our diagnostic fallacies will decrease.Keywords: Myopia; hyperopiaTurkiye Klinikleri J Ophthalmol 2007, 16:184-191
