Purpose: To assess the relationship of ocular pulse amplitude with eye structures and systemic blood pressure in healthy subjects. Material and Method: Fifty-one healthy subjects were included in the study. Ocular pulse amplitude measurement by Pascal dynamic contour tonometry, corneal pachymetry, axial length, anterior chamber depth, systolic and diastolic blood pressure measurements were performed in addition to routine ophthalmologic examination. The factors related to ocular pulse amplitude were statistically evaluated. Results: The mean age of the patients was 30.98 [+ or -] 14.4 (range: 16-66) years. Of 51 patients, 14 (27.5%) were male and 37 (72.5%) were female. The mean ocular pulse amplitude, axial length, anterior chamber depth, corneal pachymetry, systolic and diastolic blood pressure were as follows: 2.4 [+ or -] 0.8 mmHg, 23.4 [+ or -] 0.8 mm, 3.2 [+ or -] 0.3 mm, 547.2 [+ or -] 30.7 um, 118.2 [+ or -] 8.8 mmHg, 76.8 [+ or -] 4.6 mmHg. Correlation analysis showed significant association between ocular pulse amplitude and intraocular pressure (p=0.000). The associations of ocular pulse amplitude with age, gender, corneal pachymetry, anterior chamber depth, and systolic and diastolic blood pressure were not significant. Linear regression analysis showed that axial length and intraocular pressure independently affected ocular pulse amplitude. Low ocular pulse amplitude was associated with low intraocular pressure and long axial length. Discussion: Ocular pulse amplitude was significantly associated with intraocular pressure and axial length but not with age, gender and anterior eye structures. Key Words: Anterior chamber depth, axial length, corneal pachymetry, ocular pulse amplitude, systemic blood pressure AmaC: Saglikli eriskinlerde okuler nabiz amplitudu ile gozun yapisal ozellikleri ve sistemik kan basincinin iliskisini arastirmak. GereC ve Yontem: Elli bir saglikli bireyde rutin oftalmolojik muayeneye ek olarak, Pascal dinamik kontur tonometre ile okuler nabiz amplitudu, korneal kalinlik, on kamara derinligi, aksiyel uzunluk, sistolik ve diastolik arteryel kan basinci olCuldu. Okuler nabiz amplitudu ile iliskili faktorler istatistiksel olarak degerlendirildi. SonuClar: Calismaya dahil olan 51 hastanin yas ortalamasi 30,98 [+ or -] l4,4 (16-66) idi. Hastalarin 14'u (%27,5) erkek, 37'si (%72,5) kadindi. Hastalarin okuler nabiz amplitudu, aksiyel uzunluk, on kamara derinligi, santral korneal kalinlik, sistolik ve diastolik basinC ortalamalari sirasiyla 2,4 [+ or -] 0,8 mmHg, 23,4 [+ or -] 0,8mm, 3,2 [+ or -] 0,3mm, 547,2 [+ or -] 30,7um, 118,2 [+ or -] 8,8 mmHg, 76,8 [+ or -] 4,6 mmHg saptandi. Korelasyon analizi sonucunda yas, cinsiyet, santral korneal kalinlik, on kamara derinligi ve sistemik tansiyon okuler nabiz amplitudu ile iliskili bulunmazken, goz iCi basinci ile okuler nabiz amplitudu arasinda anlamli bir iliski saptandi (p = 0,000). Coklu lineer regresyon analizi ile degerlendirildiginde ise aksiyel uzunluk ve goz iCi basincinin okuler nabiz amplitudunu bagimsiz olarak etkiledigi saptandi. Dusuk okuler nabiz amplitudunun dusuk goz iCi basinci ve uzun aksiyel uzunluk ile iliskili oldugu izlendi. Tartisma: Okuler nabiz amplitudu ile aksiyel uzunluk ve goz iCi basinci arasinda anlamli bir iliski bulundu. Okuler nabiz amplitudunun yas, cinsiyet ve gozun on segment yapisal ozelliklerden etkilenmedigi gosterildi. Anahtar Kelimeler: Aksiyel uzunluk, korneal kalinlik, okuler nabiz basinci, on kamara derinligi, sistemik kan basinci
