Abstract

Pur po se: To evaluate the clinical findings of toxic keratopathies secondary to topical proparacaine (Alcaine, Alcon) abuse and the results of medical and/or surgical treatment options. Ma te ri al and Met hod: We retrospectively analyzed twenty-two eyes of 25 patients who developed toxic keratopathy secondary to topical anesthetic abuse between March 2005 and December 2009. Severe pain unresponsive to medical treatment with persistent epithelial defects (PED) and stromal ulcers were managed with amniotic membrane transplantation (AMT). Some cases have undergone optical penetrating keratoplasty (PK). Clinical findings and complications were assessed, and visual acuities were measured before and after treatment. At the sixthmonth follow-up visit, endothelial cell densities (ECD) were determined with specular microscopy in both affected and unaffected eyes for statistical comparison. Re sults: The mean time interval between the initiation of topical anesthetic use and admission to our clinic was 2.26 months. Epithelial defects, circular stromal keratitis and corneal edema were present in all eyes. Epithelial defects were healed with medical treatment in 15 eyes (60%). AMT was performed in 10 eyes, following a mean of 26.1 days after initiation of medical treatment. Visual acuity before the treatment was 0.1 or below in all eyes. At the last control visit including 3 eyes having had PK, best-corrected visual acuities were 0.5 or better in 13 eyes (52%), between 0.2 and 0.4 in 7 eyes (28%) and 0.1 or worse in 5 eyes (20%). No statistically significant difference was found between ECD of affected and unaffected eyes of 13 patients in whom specular microscopy was possible. Dis cus si on: Topical anesthetic abuse may cause severe toxic keratopathy and lead to significant visual loss related to stromal opacities despite intensive treatment. AMT was found effective and successful in healing PED and stromal ulcers as well as in breaking the vicious circle of anesthetic abuse with the relief of pain.

Özet

Amaç: Topikal anestezik proparakain (Alcaine, Alcon) aşırı dozda kullanılması sonucu gelişen toksik keratopatilere ait klinik bulguları, medikal ve cerrahi tedavi sonuçlarını değerlendirmek. Ge­reç ve Yön­tem: Mart 2005 ve Aralık 2009 tarihleri arasında, topikal anestezik aşırı dozda kullanılması sonrası toksik keratopati gelişen 22 hastanın 25 gözü incelendi. Tüm gözler başlangıçta medikal olarak tedavi edildi. Medikal tedavi ile düzelmeyen şiddetli ağrı ile birlikte inatçı epitel defekti (İED) ve stromal ülserlerin tedavisinde amniyon membran transplanatsyonu (AMT) yapıldı. Bazı olgularda gerektiğinde optik amaçla penetran keratoplasti (PK) yapıldı. Tedavi öncesi ve sonrası görme keskinliği ölçüldü, klinik bulgular değerlendirildi. Hastaların tedavi sonrası 6.ncı ayda sağlam ve etkilenmiş gözlerinde endotel hücre sayısı ölçüldü ve istatistiksel analizleri yapıldı. Ortalamalar arasındaki farkların incelenmesinde Paired Samples T Test ve Wilcoxon Signed Rank Test kullanıldı.Sonuçlar: Hastaların topikal anestezik kullanımına başlaması ile kliniğimize başvuru arasında geçen süre ortalama 2,26 aydı. İlk kontrolde tüm gözlerde epitel defekti, halka şeklinde stromal keratit ve korneal ödem teşhis edildi. Medikal tedavi sonucu 15 (%60) gözde epitel defekti iyileşti. On gözde, medikal tedavi başlangıcından ortalama 26,1 gün sonra AMT yapıldı. Tedavi öncesi tüm gözlerde görme keskinliği 0,1 ve daha azdı. Son kontrolde PK yapılan 3 gözle birlikte düzeltilmiş en iyi görme keskinliği 13 gözde (%52) 0,5 ve daha iyi, 7 gözde (%28) 0,2 ile 0,4 arasında ve 5 gözde (%20) 0,1 ve daha az olarak bulundu. Tedavi sonrası ölçüm yapılabilen 13 hastada, sağlam ve etkilenmiş gözler arasında endotel hücre sayısı yönünden istatistiksel olarak anlamlı bir fark yoktu (p
