What Are We Missing From Asymmetric Relationship Between the Retinal Nerve Fiber Layer Thickness Profiles and Sphenoid Sinus Volume?

Ozdemir, Dogukan/0000-0003-2008-163XWOS: 000529353700041PubMed: 31633664Purpose/Aim of the Study:Detailed analysis of retinal structure such as the retinal nerve fiber layer can be performed by spectral-domain optical coherence tomography (OCT). There are no published studies concerning a relationship between retinal nerve fiber layer and human sphenoid sinus volumes. We investigated this relationship.Material and Methods:Spectral-domain OCT. the peripapillary retinal nerve fiber layer (RNFL) thickness and sphenoid sinus volume estimation of both sides of sex-matched patients were retrospectively analyzed.Results:The mean RNFL thicknesses at the left side (91.8 mu m) were significantly smaller than the right side (94.5 mu m) (P=0.040). However, the mean left sinus volume (44.5cm(3)) is larger than the right side, (34.5mm(3)) (P<0.005). Left and right differences of both parameters are statistically significant (P
