The Effects of Nasal Septum Deviation on Ocular Examination Findings: Does Deviated Nasal Septum Cause Impaired Vision?

Abstract

Aim: Nasal obstruction due to nasal septum deviation is associated with systemic diseases such as cardiopulmonary disease, neurological and vascular problems. But the effect of pure nasal deviation on the ocular system has not been precisely investigated. The aim of this study was to analyze the association of nasal septal deviation with ocular examination findings. Material and Methods: Twenty-seven adult patients underwent septoplasty and 31 controls were included in the study. The study group was conducted on patients with pure nasal septum deviation which is significantly obstructing the nasal airway (>50%). In ophthalmological examination; peripapillary retinal nerve fiber layer, macular and choroidal thickness measurements were obtained. The examination findings were compared between the study and control groups. Results: The mean macular thicknesses at nasal-500μm were 305.89±32.79 and 287.87±25.00 in the study and control groups, respectively (p=0.021). The mean macular thicknesses at nasal-1000μm were 353.04±21.28 and 341.16±17.97 in the study and control groups, respectively (p=0.025). The mean thickness of choroid was statistically significantly different at central (p=0.036) and peripheral measurements; nasal-500μm (p=0.020); nasal-1000μm (p=0.001); nasal-1500μm (p<0.001); temporal-500μm (p=0.023) and temporal-1000μm (p=0.045). No statistically significant difference was found between the two groups according to ocular tension, thickness of cornea, keratometry, anterior chamber depth, axial length of cornea, and retinal nerve fiber layer thickness. Conclusion: This is one of the pioneer studies evaluating the ocular examination findings in patients with nasal septum deviation. Our results indicate the increased thickness of both macula and choroid in patients with nasal septum deviation.

Nazal Septum Deviasyonunun Göz Muayenesi Bulgularına Etkileri: Nazal Septum Deviasyonu Görme Bozukluğuna Sebep Olur mu?

Abstract

Amaç: Nazal septum deviasyonuna bağlı burun tıkanıklığı, kardiyopulmoner hastalık, nörolojik ve vasküler problemler gibi sistemik hastalıklar ile ilişkilidir. Ancak saf nazal deviasyonun oküler sistem üzerindeki etkisi tam olarak araştırılmamıştır. Bu çalışmanın amacı nazal septal deviasyonun oküler muayene bulguları ile ilişkisini incelemektir. Gereç ve Yöntemler: Bu çalışmaya septoplasti yapılmış olan 27 yetişkin hasta ve 31 kontrol dahil edildi. Çalışma grubu nazal hava yolunda ciddi bir şekilde tıkanıklık (>50%) oluşturan sadece nazal septum deviasyonlu hastalar ile oluşturuldu. Göz muayenesinde; perifer retina sinir lifi tabakası, makuler ve koroid kalınlık ölçümleri elde edildi. Muayene bulguları çalışma ve kontrol grupları arasında karşılaştırıldı. Bulgular: Çalışma ve kontrol gruplarında nazal-500μm'deki ortalama makula kalınlıkları sırasıyla 305,89±32,79 ve 287,87±25,00 idi (p=0,021). Nazal-1000μm'deki ortalama makula kalınlıkları çalışma ve kontrol gruplarında sırasıyla 353,04±21,28 ve 341,16±17,97 idi (p=0,025). Ortalama koroid kalınlığı santral (p=0,036) ve periferal ölçümlerde; nasal-500μm (p=0,020), nazal-1000μm (p=0,001), nasal-1500μm (p<0,001), temporal-500μm (p=0,023) ve temporal-1000μm (p=0,045) istatistiksel olarak anlamlı şekilde farklıydı. Oküler tansiyon, kornea kalınlığı, keratometri, ön kamara derinliği, kornea aksiyel uzunluğu ve retina sinir lifi tabakası kalınlığı açısından iki grup arasında istatistiksel olarak anlamlı bir farklılık bulunmadı. Sonuç: Bu çalışma nazal septum deviasyonu olan hastalarda oküler muayene bulgularını değerlendiren öncü çalışmalardan biridir. Sonuçlarımız, nazal septum deviasyonu olan hastalarda hem makula hem de koroid kalınlığının arttığını göstermektedir.
