Amaç: Bu çalışma, Sistemik Lupus Eritematozus (SLE) hastalarında ön segment parametreleri, oküler pulse amplitüdü (OPA) ve koroid kalınlığı arasındaki ilişkiyi sağlıklı bireylerle karşılaştırmalı olarak değerlendirmeyi amaçlamıştır. Gereç ve Yöntemler: Prospektif kesitsel tasarımlı bu çalışmaya, SLE tanılı 8 hastanın 16 gözü ile 8 sağlıklı bireyin 16 gözü dâhil edilmiştir. SLE tanısı, 1997 revize Amerikan Romatoloji Derneği kriterlerine göre doğrulanmıştır. Katılımcılara detaylı oftalmolojik muayene yapılmış; dinamik kontur tonometresi kullanılarak OPA ölçümleri gerçekleştirilmiş ve Spektral Domain Optik Koherens Tomografi cihazının artırılmış derinlik modu ile koroid kalınlığı değerlendirilmiştir. İstatistiksel analiz SPSS 27.0 yazılımı kullanılarak yapılmıştır. Bulgular: SLE grubunda OPA değerleri anlamlı derecede düşük bulunmuştur (SLE: 2,3±1,7 mmHg, Kontrol: 2,8±1,0 mmHg, p=0,032). Ön kamara derinliği, SLE grubunda 2,9±0,3 mm, kontrol grubunda ise 3,6±0,3 mm olarak ölçülmüş ve bu fark istatistiksel olarak anlamlı bulunmuştur (p<0,001). Subfoveal koroid kalınlığı SLE grubunda kontrol grubuna kıyasla hafif yüksek (SLE: 316,3±69,5 µm, Kontrol: 301,0±59,5 µm) bulunmasına rağmen bu fark istatistiksel olarak anlamlı değildir (p=0,510). Kornea histerezisi ve kornea direnç faktörü gibi diğer ön segment parametrelerinde anlamlı bir farklılık gözlenmemiştir. Sonuç: SLE hastalarında OPA ve ön kamara derinliğinde azalma, oküler hemodinamik değişiklikleri ve ön segment yapılarındaki potansiyel etkileri işaret etmektedir. Subfoveal koroid kalınlığı açısından anlamlı bir farklılık olmamakla birlikte, SLE'nin oküler yapı üzerindeki etkilerini anlamak için uzunlamasına çalışmalara ihtiyaç vardır.

Objective: This study aimed to evaluate the relationship between anterior segment parameters, ocular pulse amplitude (OPA), and choroidal thickness in patients with Systemic Lupus Erythematosus (SLE) and compare them with healthy individuals. Material and Methods: This prospective cross-sectional study included 16 eyes of 8 patients diagnosed with SLE and 16 eyes of 8 healthy individuals. The diagnosis of SLE was confirmed according to the revised 1997 American College of Rheumatology criteria. Participants underwent a comprehensive ophthalmological examination; OPA measurements were performed using dynamic contour tonometry, and choroidal thickness was assessed with the enhanced depth imaging mode of the Spectral Domain Optical Coherence Tomography device. Statistical analysis was conducted using SPSS 27.0 software. Results: OPA values were found to be significantly lower in the SLE group (SLE: 2.3±1.7 mmHg, Control: 2.8±1.0 mmHg, p=0.032). Anterior chamber depth was measured as 2.9±0.3 mm in the SLE group and 3.6±0.3 mm in the control group, with a statistically significant difference (p<0.001). Although subfoveal choroidal thickness was slightly higher in the SLE group compared to the control group (SLE: 316.3±69.5 µm, Control: 301.0±59.5 µm), this difference was not statistically significant (p=0.510). No significant differences were observed in other anterior segment parameters, such as corneal hysteresis and corneal resistance factor. Conclusion: The reduction in OPA and anterior chamber depth in SLE patients indicates potential ocular hemodynamic changes and structural effects on the anterior segment. Although no significant difference was found in subfoveal choroidal thickness, longitudinal studies are needed to better understand the ocular impact of SLE.
