Role of axial length in brunch retinal vein occlusion

Key Findings & Data:Materials and Methods: It was examined whether there were any differences in terms of axial length and refraction in the involved eyes of 30 patients with unilateral branch retinal vein occlusion (Group 1), uninvolved eyes of the same (Group 2), and 34 eyes of the 17 normal individuals (Group 3, control group).

💡

Conclusion & Impact:Hyperopia was found in 8 patients with branch retinal vein occlusion (26.7%) while, it was found only in 2 patients (5.9%) in the control group.

Abstract

Purpose: To examine the role of axial length and refraction in branch retinal vein occlusion. Materials and Methods: It was examined whether there were any differences in terms of axial length and refraction in the involved eyes of 30 patients with unilateral branch retinal vein occlusion (Group 1), uninvolved eyes of the same (Group 2), and 34 eyes of the 17 normal individuals (Group 3, control group). Result: Mean axial lenght was found 22.19±0.98 mm (20.44-23.96 mm) in group 1 whereas it was 22.20±0.97 mm (20.30-24.02 mm) in group 2, and 22 75±0.66 mm(21.46- 23.99 mm) in group 3. There was no statistically significant difference between group 1 and group 2 in terms of axial length (p>0.05) however the difference between group 1 and group 3 was statistically significant (p<0.05). Hyperopia was found in 8 patients with branch retinal vein occlusion (26.7%) while, it was found only in 2 patients (5.9%) in the control group. No statistically significant difference was found between the two groups. Conclusion: Axial length is significantly shorter in cases with venous branch occlusion. This condition can be considered as an additional local risk factor for venous branch occlusion.

Özet

Amaç: Ven dal tıkanıklığı (VDT) olan olgularda aksiyel uzunluk ve refraksiyonun rolünü araştırmak. Gereç ve Yöntem: Tek taraflı ven dal tıkanıklığı olan 30 olgunun etkilenen gözleri (Grup 1) sağlam gözleri (Grup 2) 17 normal olgudan oluşan kontrol grubunun 34 gözü (Grup 3) arasında aksiyel uzunluk ve refraksiyon yönünden fark olup olmadığı araştırıldı. Bulgular: Grup 1 de ortalama aksiyel uzunluk 22.19±0.98 mm (20.44-23.96 mm) iken Grup 2 de 22.20±0.97 mm (20.30- 24.02 mm), Grup 3 de 22.75±0.66 mm(21.46-23.99 mm) idi. Grup 1 ve 2 arasında aksiyel uzunluk yönünden istatiksel olarak anlamlı fark bulunmazken; (p>0.05) Grup 1 ile 3 arasında istatiksel olarak anlamlı fark bulundu (p<0.05). Ven dal tıkanıklığı olan olguların sekizinde (%26.7) kontrol grubu olgularının ikisinde (%5.9) hipermetropi saptandı. İki grup arasında istatiksel olarak anlamlı fark bulunmadı. Sonuç: Ven dal tıkanıklığı olan olgularda aksiyel uzunluk istatistiksel olarak anlamlı derecede daha kısadır. Bu durum ven dal tıkanıklığı için ek bir lokal risk faktörü sayılabilir.
