Abstract

Purpose: To assess retinal functions by full-field electroretinography (ERG) in children with acute mercury poisoning. Material and Method: Twelve children acutely exposed to elemental mercury as a result of a broken thermometer (2x20 cm in size) in the science laboratory that was undiscovered over one day were included to the study. The amount of exposed mercury was about 1 ml. Age- and sex-matched 13 healthy children were employed as control group. Full-field ERG recordings were performed following a detailed ophthalmological examination for all cases and the recordings were compaired. Results: Best-corrected visual acuity was 10/10 in all children. Mean intraocular pressure was 14.9±1.7 mmHg . No significant change was detected in any children in fundus examination. In the comparison of ERG parameters between patient and control groups, rod amplitude, maximum combined response amplitude, oscillatory potential amplitude and cone amplitude of both eyes were significantly lower in the patient group than the control group (p<0.05). Conclusion: Elementary mercury can be found in many daily using tools. The result of unsuitable usage of this tools especially children can exposure of mercury. Acute mercury intoxication can affect all systems also with visual system. Therefore, all employee and students should be aware of the tools containing mercury and toxicity risk of mercury especially in the schools

Özet

Amaç: Akut civa intoksikasyonu olan çocuklarda tam alan ERG ile retinal fonksiyonun değerlendirilmesi.Gereç ve Yöntem: Bu çalışmaya fen bilimleri laboratuvarında 2x20 cm boyutundaki termometrenin kırılması ve 1 gün boyunca fark edilmemesi sonucu elementer civaya akut olarak maruz kalan 12 çocuk dahil edildi. Maruz kalınan civa miktarı yaklaşık 1 ml idi. Yaş ve cinsiyet açısından uyumlu, sağlıklı 13 çocuk kontrol grubu olarak çalışmaya dahil edildi. Tüm olguların ayrıntılı göz muayenesini takiben tam alan ERG kayıtları alındı. Bulgular: Tüm çocukların en iyi düzeltilmiş görme keskinliği 10/10 idi. Ortalama göz içi basıncı 14.9±1.7 mmHg idi. Tüm çocukların fundus muayenesinde önemli bir değişiklik saptanmadı. Hasta ve kontrol grubu arasındaki ERG parametrelerinin karşılaştırmasında ise hasta grubunda her iki gözde rod amplitüdü, maximal kombine yanıt amplitüdü, osilatuar potansiyel (OP) amplitüdü ve koni amplitüdü kontrol grubundan anlamlı derecede düşük bulundu (p<0.05). Sonuç: Güncel hayatımızda kullandığımız pek çok aletin içerisinde civa bulunmaktadır ve bu aletlerin özellikle çocuklar tarafından uygunsuz kullanımı sonucunda civaya maruziyet olabilmektedir. Kısa süreli de olsa civaya maruziyet tüm vücudumuzu etkileyebileceği gibi görsel sistemide etkileyebilir. Bu nedenle özellikle okullarda tüm çalışanlar ve öğrenciler civanın toksikasyon riski açısından bilinçlendirilmelidirler
