The Importance of Refractive Status and Axial Length in Patients with Subconjunctival Hemorrhage

Öz

Subconjunctival hemorrhage(SCH) is a painless disease that occurs as a result of the localized extravasation of blood to subconjunctival tissue and episcleral space by suddenly rupturing conjunctival vessels. Our aim is evaluate the refractive status, axial length and anterior segment parameters in patients with subconjunctival hemorrhage in this study. A fifty-one eye of 51 patients with subconjunctival hemorrhage and 40 eyes of 40 healthy individuals were enrolled in this prospective study. In detail, systemic diseases, used drugs, and other risk factors were questioned. After demographic questioning, a detailed biomicroscopy eye examination was performed for risk factors. Then refractive error, intraocular pressure, axial length, lens thickness, central corneal thickness, and anterior chamber depth were measurements performed. The mean age of patients with SCH was 49.4±6.8 (28-59) and the mean age of the control group was 50.4±6.8 (32-57). In terms of risk factors of SCH, the patients were divided into 3 groups that had sufficient statistical analysis (HT, use of anticoagulants and history of Valsalva). According to results, a significant difference was found between patients with HT and control groups in terms of spherical refraction (hyperopia) (p<0.001), short axial length (p<0.001) and narrow anterior chamber depth (p<0.001). In addition a significant negative correlation between axial length and SCH repeat number (p= 0.036, r =-0.544). No significant difference was detected between anticoagulant usage-Valsalva patients and the control group in terms of refractive error, anterior segment parameters and axial length(p>0.05). If the hyperopia, short axial length, and narrow anterior camera are detected in the examination of patients with SCH, the patients should be investigated in detail in terms of HT. In addition, eye related parameters were found to be important in SCH etiology.

Subkonjonktival Kanaması olan Hastalarda Refraktif Durum ve Aksiyel Uzunluğun Önemi

Öz

Subkonjonktival kanama (SKH), konjonktival damarların aniden yırtılması ile kanın subkonjonktival dokuya ve episkleral boşluğa lokalize sızması sonucu ortaya çıkan ağrısız bir hastalıktır. Bu çalışmada amacımız subkonjonktival kanamalı hastalarda refraktif durum, aksiyel uzunluk ve ön segment parametrelerini değerlendirmektir. Bu prospektif çalışmaya subkonjonktival kanaması olan 51 hastanın 51 gözü ve 40 sağlıklı bireyin 40 gözü dahil edildi. Ayrıntılı olarak sistemik hastalıklar, kullanılan ilaçlar ve diğer risk faktörleri sorgulandı. Demografik sorgulamadan sonra risk faktörleri için ayrıntılı biyomikroskopi göz muayenesi yapıldı. Daha sonra kırma kusuru, göz içi basıncı, eksenel uzunluk, lens kalınlığı, santral kornea kalınlığı ve ön kamara derinliği ölçümleri yapılarak sonuçlar kaydedildi. SKH'li hastaların yaş ortalaması 49.4±6.8 (28-59) ve kontrol grubunun yaş ortalaması 50.4±6.8 (32-57) idi. SKH risk faktörleri açısından hastalar yeterli istatistiksel analize sahip 3 gruba ayrıldı (HT, antikoagülan kullanımı ve Valsalva öyküsü). Sonuçlara göre, HT'li hastalar ile kontrol grupları arasında hipermetrop (p <0.001), kısa aksiyel uzunluk (p<0.001) ve dar ön kamara derinliği (p<0.001) açısından anlamlı bir fark saptandı. Ek olarak, aksiyel uzunluk ile SKH tekrar sayısı arasında anlamlı negatif korelasyon(p=0.036, r=-0.544) saptandı. Antikoagülan kullanımı ve Valsalva öyküsü olan hastalar ile kontrol grubu arasında kırma kusuru, ön segment parametreleri ve aksiyel uzunluk açısından anlamlı fark bulunmadı (p> 0.05). SKH'li hastaların muayenesinde hipermetrop, kısa aksiyel uzunluk ve dar ön kamera tespit edilirse, hastalar HT açısından ayrıntılı olarak araştırılmalıdır. Ek olarak SKH etiyolojisinde gözle ilgili parametrelerin de önemli olduğu bulunmuştur.
