Conclusion: OXA treatment can be responsible for sight threatening side effects by influencing different parts of the ophthalmic system; therefore, oncologists and ophthalmologists should keep in mind the irreversibl-ophthalmic adverse effects of OXA treatment in oncology patients.

Özet

Objective: Visual disturbances occurring during cancer treatment with oxaliplatin (OXA) have been previously reported in some of case presentations. This study investigates the ocular toxicity of OXA on rat eye tissues by using histopathological staining. Additionally, the reversibility of findings, if there is any, were assessed in groups with waiting periods. Method: Six-8 month-old rats have been separated into five groups. Acute OXA treatment (4 mg/kg) has been administered on days 1, 3 and 5th days; consequently, the eye samples were obtained on 7th and 14th days of the study. Chronic OXA treatment (4 mg/kg) has been administered for 4 weeks (two days of week); the rats were sacrificed on 28th day and 21 days after completing administration of drug. One group was used as a control. Results: The most striking irreversible-features of OXA treatment were endothelial polypoid proliferation of the vessel, neo-vascularisation of cornea, capillarisation of optic nerve and, degeneration of retinal nerve fibre layer at several degrees of severity. Conclusion: OXA treatment can be responsible for sight threatening side effects by influencing different parts of the ophthalmic system; therefore, oncologists and ophthalmologists should keep in mind the irreversibl-ophthalmic adverse effects of OXA treatment in oncology patients.

Abstract

Amaç: Oksaliplatin (OKSA) ile yapılan kanser tedavileri sırasında görme bozuklukları bir kaç olgu sunumunda bildirilmiştir. Bu çalışma histopatolojik boyama kullanarak sıçan göz dokularında oksaliplatinin göz toksisitesini araştırmaktadır. İlave olarak, eğer bir bulgu varsa, bulguların geri dönüşümlü olup olmadığı da bekleme süresi olan gruplarda değerlendirildi. Yöntem: 6-8 aylık sıçanlar beş gruba ayrıldı. Akut OKSA tedavisi (4 mg/kg) 1., 3. ve 5. günlerde verildi, sonrasında, göz dokuları 7. ve 14. günde elde edildi. Kronik OKSA tedavisi (4 mg/kg), 4 hafta boyunca (hafta da 2 gün) uygulandı; sıçanlar 28. günde ve ilaç uygulamasının sonlandırılmasını takiben 21 gün beklenerek kesildi. Bir grup kontrol olarak kullanıldı. Bulgular: OKSA tedavisinin en göze çarpan geri-dönüşümsüz bulguları, damar endotelinde polipoid proliferasyon, korneada yeni damar oluşumu, optik sinir kapillerlerinde artış ve retinal sinir lifi tabakasında farklı derecelerde dejenerasyondu. Sonuç: OKSA tedavisi oftalmik sistemin farklı bölümlerini etkileyerek görmeyi tehtid eden yan etkilerden sorumlu olabilir, bu nedenle onkolog ve oftalmolog OKSA ile tedavi edilen onkoloji hastalarında geri dönüşümsüz oftalmik yan etkiler olabileceğini akılda bulundurmalıdır.
