Abstract

Amaç: Sistemik skleroz (SSc) hastalarında kornea ve diğer ön segment yapılarındaki değişiklikleri gözlemlemek.
Yöntem: Bu retrospektif karşılaştırmalı vaka serisine SSc için takip edilen 22 hastanın 41 gözü dahil edildi. Kontrol grubu ayrıca yaş ve cinsiyet açısından uyumlu 22 katılımcının 42 gözünü içeriyordu. Demografik veriler, oküler görüntüleme sonuçları ve ayrıntılı oküler muayene bulguları hasta dosyalarından elde edildi. Tüm hastalara tam oftalmolojik muayeneye ek olarak kornea topografisi ve ön segment optik koherens tomografi (OKT) ölçümleri yapıldı.
Bulgular: Kornea topografisi ve OKT ölçümleri arasında santral kornea kalınlığı (SKK) açısından çok yüksek pozitif korelasyon vardı (katsayı=0,985, p<0,001). Hem kornea topografisi (p=0,012) hem de OKT (p=0,002) ile ölçülen SKK, SSc hastalarında daha ince saptandı. SSc hastalarında topografi ile ölçülen kornea hacminde (KH) anlamlı bir azalma vardı (p=0,013). OKT ile kornea alt katmanlarının analizinde, SSc hastalarında kornea stroma kalınlığı (SK) (p=0,001) ve gözyaşı film tabakası kalınlığı (GK) (p<0,001) anlamlı derecede düşük bulundu. Ancak kornea epitel tabakası kalınlığı (p=0,316), Bowman membran tabakası kalınlığı (p=0,709) ve Descemet membran tabakası kalınlığı (0,344) açısından anlamlı kalınlık farkı saptanmadı. Korneanın ön yüzeyinin keratometri dik (Kd) (p=0,855) ve keratometri yatay (Ky) (p=0,704) değerleri, kornea arka yüzeyinin Kd (0,901) ve Ky (p=0,435) değerleri, ön kamara derinliği (0,635), ön kamara hacmi (0,861) ve topografi ile ölçülen ön kamara açısı (0,982) açısından anlamlı değişim saptanmadı.
Sonuç: SKK, GK,SK ve KH SSc hastalarında anlamlı şekilde azalmaktadır. Bu sebeple hastalığın kontrolünde bu parametrelerin yakından takibi bir yol gösterici olabilir.

Ocular Anterior Segment Changes in Patients with Systemic Sclerosis

Abstract

Objective: To observe changes in the cornea and other anterior segment structures in patients with systemic sclerosis (SSc).
Methods: This retrospective comparative case series included 41 eyes of 22 patients followed for SSc. The control group also included 42 eyes of 22 age- and sex-matched participants. Demographic data, ocular imaging results, and detailed ocular examination findings were obtained from patient files. In addition to the complete ophthalmological examination, corneal topography and anterior segment optical coherence tomography (OCT) measurements were performed on all patients.
Results: There was a highly positive correlation between corneal topography and OCT measurements in terms of central corneal thickness (CCT) (coefficient=0.985, p<0.001). CCT measured by both corneal topography (p=0.012) and OCT (p=0.002) was found to be thinner in SSc patients. There was a significant decrease in corneal volume (CV) measured by topography in SSc patients (p=0.013). In the analysis of corneal sublayers by OCT, corneal stroma thickness (ST) (p=0.001) and tear film layer thickness (TT) (p<0.001) were found to be significantly lower in SSc patients. However, there was no significant difference in thickness in terms of corneal epithelial layer thickness (p=0.316), Bowman's membrane layer thickness (p=0.709), and Descemet's membrane layer thickness (p=0.344). Keratometry steep (Ks) (p=0.855), keratometry flat (Kf) (p=0.704) values of the anterior surface of the cornea, Ks (p=0.901), and Kf (p=0.435) values of the posterior surface of the cornea, anterior chamber depth (p=0.635), anterior chamber volume (p=0.861), and anterior chamber angle (p=0.982) measured by topography were not found to be significant between the groups.
Conclusion: CCT, TT, ST, and CV are significantly reduced in SSc patients. For this reason, close monitoring of these parameters in the control of the disease may be a guide.
