Abstract

Purpose: The ocular pulse amplitude (OPA) is the difference between systolic and diastolic intraocular pressure (IOP). The purpose of this study was to assess the relationship of OPA with systemic blood pressure and ocular biometric factors in healthy subjects. Materials and Methods: 104 healthy subjects aged between 40-75 years were included in the study. Ocular pulse am- plitude and IOP were measured by dynamic contour tonometry, and central corneal thickness (CCT), axial length (AL), anterior chamber depth (ACD), and systolic and diastolic blood pressure (SBP and DBP) measurements were performed in addition to a routine ophthalmologic examination. Associations between OPA and IOP, SBP, DBP, AL, CCT and ACD were analyzed with Pearson correlation analysis. Results: A total of 208 eyes of 104 cases were included in the study. The mean age of the patients was 51.02 (±6.68) years with 49 (47.1%) females and 55(52.9%) males. Mean values were as follows: OPA 2.92±1.68 mmHg, AL 23.2±0.91 mm, CCT 546.6±34.8 μm, ACD 3.1±0.5 mm, SBP 134.6±25.4 mmHg and DBP 76.2±13.6 mmHg. Correlation analysis showed signifi- cant association between OPA and IOP (p=0.000). Low OPA was associated with low IOP and long AL, whereas no correla- tion was found between age, sex, SBP, ACD and CCT with OPA. Conclusion: In healthy subjects, ocular pulse amplitude was significantly associated with intraocular pressure and axial length but not with age, anterior eye structures and systemic blood pressure.

Özet

Amaç: Oküler nabız amplitüdü (ONA), sistolik ve diyastolik göz içi basıncı (GİB) farkıdır. Bu çalışmanın amacı, sağlıklı bireylerde ONA değerinin, sistemik kan basıncı ve oküler biyometrik faktörlerle ilişkisini araştırmaktır. Gereç ve Yöntem: Yaşları 40-75 arası olan 104 sağlıklı birey çalışmaya dahil edildi. Çalışma kapsamındaki tüm olgulara rutin oftalmolojik muayeneye ek olarak dinamik kontur tonometri ile GİB ve ONA ölçümü, santral korneal kalınlık (SKK), aksiyel uzunluk (AU),ön kamara derinliği (ÖKD) ve sistolik ve diyastolik kan basıncı (SKB ve DKB) ölçümleri yapıldı. ONA ile GİB, SKB ve DKB, AU, SKK ve ÖKD arasında korelasyon analizi için Pearson korelasyon analizi kullanıldı. Bulgular: Çalışmaya dahil olan 104 hastanın 208 gözü çalışma kapsamına alındı. Ortalama yaş 51.02 (±6.68) yıl olarak bulundu. Hastaların 49’u (%47.1) kadın, 55’i (%52.9) erkekti. Ortalama ONA 2.92±1.68 mmHg, AU 23.2±0.91 mm, SKK 546.6±34.8 μm, ÖKD 3.1±0.5 mm, SKB 134.6±25.4 mmHg ve 76.2±13.6 mmHg olarak saptandı. ONA ile GİB arasında an- lamlı korelasyon saptandı (p=0.000). Yaş, cinsiyet, sistemik kan basıncı, ÖKD ve SKK ile ONA arasında anlamlı korelasyon saptanmazken, düşük ONA değerlerinin, düşük GİB ve yüksek AU değeri ile ilişkili olduğu görüldü. Sonuç: Sağlıklı kişilerde ONA değerleri, aksiyel uzunluk ve göz içi basıncı ile ilişkilidir ancak ONA ile yaş, ön segment ve sistemik kan basıncı parametreleri arasında ilişki saptanmamıştır.
