Choroidal thickness changes in connective tissue diseases

Amaç: Çalışmanın amacı bağ dokusu hastalıklarında (BDH) koroid kalınlığı (KK) değişikliklerinin Spektral Domein optik koherens tomografi (SD OKT) kullanılarak değerlendirilmesidir.Gereç ve Yöntemler: Bu prospektif klinik çalışmada, en az 3 aydır remisyonda olan ve bağ dokusu hastalığı tanısı almış 34 hasta ve yaş ve cinsiyet uyumu olan 30 sağlam kişi kontrol grubu olarak değerlendirilmiştir. Santral makula kalınlığı (SMK) subfoveal, nazal ve temporal 500, 1500 mikron mesafelerdeki KK, SD OKT ile ölçülmüştür.Bulgular: Hasta grubunda ortalama SMK (219,2 ?m) kontrol grubuna göre (225,5 ?m) daha ince bulunmuştur. Ancak aradaki fark istatistiksel olarak anlamlı değildi (P = 0,2). Aynı zamanda ortalama KK her ölçüm noktası için hasta grubunda incelmiş olarak bulunmuştur fakat aradaki fark yine istatistiksel olarak anlamlı değildi (P > 0,05). Sonuçlar: İstatistiksel olarak anlamlı olmamasına rağmen BDH'larında koroid dokusu kalınlığı incelmiş olarak bulunmuşturAim: The aim of this study is to evaluate the choroidal thickness (CT) changes in connective tissue disease (CTD) using spectral domain optical coherence tomography (SD OCT) with enhanced depth imaging (EDI).Material and Methods: In this prospective clinical study, we included 34 subjects who were diagnosed as CTD in remission for at least 3 months, and age and gender matched 30 healthy controls. Central macular thickness (CMT), subfoveal CT, and CT at nasal (N) and temporal (T) distances of 500 ?m (N500 and T500, respectively) and 1500 ?m (N500 and T1500, respectively) from the central fovea were measured by EDI OCT.Results: The mean CMT of the patient group (219.2 ?m) was thinner compared to the control group (225.5 ?m), but the difference was not statistically significant (P = 0.2). At the same time, mean CT values were thinner at all measure points in the CTD subjects. The mean subfoveal CT, N500, N1500, T500 and T1500 were not significantly different in comparison to controls (all P > 0.05). Conclusion: Although our results did not reach statistical significance, we found that choroidal tissue was thinner in patients with CT

Pedicle morphology of the thoracic spine in preadolescent idiopathic scoliosis: magnetic resonance supported analysis

Although several studies have been reported on the adult vertebral pedicle morphology, little is known about immature thoracic pedicles in patients with idiopathic scoliosis. A total of 310 pedicles (155 vertebrae) from T1 to T12 in 10–14 years age group were analyzed with the use of magnetic resonance imaging and digital measurement program in 13 patients with right-sided thoracic idiopathic scoliosis. Each pedicle was measured in the axial and sagittal planes including transverse and sagittal pedicle width and angles, chord length, interpedicular distance and epidural space width on convex and concave sides of the curve. The smallest transverse pedicle widths were in the periapical region and the largest were in the caudal region. No statistically significant difference in transverse pedicle widths was detected between the convex and concave sides. The transverse pedicle angle measured 15.56° at T1 and decreased to 6.32° at T12. Chord length increased gradually from the cephalad part of the thoracic spine to the caudad part as the shortest length was seen at T1 convex level with a mean of 30.45 mm and the largest length was seen at T12 concave level with a mean of 41.73 mm. The width of epidural space on the concave side was significantly smaller than that on the convex side in most levels of the curve. Based on the anatomic measurements, it may be reasonable to consider thoracic pedicle screws in preadolescent idiopathic scoliosis
