Oküler Nabız Amplitüdü ile Gözün Yapısal Özellikleri ve Sistemik Kan Basıncının İlişkisi

Pur po se: To assess the relationship of ocular pulse amplitude with eye structures and systemic blood pressure in healthy subjects.\udMa te ri al and Met hod: Fifty-one healthy subjects were included in the study. Ocular pulse amplitude measurement by Pascal dynamic\udcontour tonometry, corneal pachymetry, axial length, anterior chamber depth, systolic and diastolic blood pressure measurements were\udperformed in addition to routine ophthalmologic examination. The factors related to ocular pulse amplitude were statistically evaluated.\udRe sults: The mean age of the patients was 30.98±14.4 (range: 16-66) years. Of 51 patients, 14 (27.5%) were male and 37 (72.5%) were\udfemale. The mean ocular pulse amplitude, axial length, anterior chamber depth, corneal pachymetry, systolic and diastolic blood pressure\udwere as follows: 2.4±0.8mmHg, 23.4±0.8 mm, 3.2±0.3 mm, 547.2±30.7 μm, 118.2±8.8 mmHg, 76.8±4.6 mmHg. Correlation analysis\udshowed significant association between ocular pulse amplitude and intraocular pressure (p=0.000). The associations of ocular pulse amplitude\udwith age, gender, corneal pachymetry, anterior chamber depth, and systolic and diastolic blood pressure were not significant. Linear regression\udanalysis showed that axial length and intraocular pressure independently affected ocular pulse amplitude. Low ocular pulse amplitude was\udassociated with low intraocular pressure and long axial length.\udDis cus si on: Ocular pulse amplitude was significantly associated with intraocular pressure and axial length but not with age, gender and\udanterior eye structures.
