Scleral Tunnel Rupture Following Trauma 12 Years After Small Incision Cataract Surgery: Case Report

Abstract

ound sealing has been shown to be more secure in scleral tunnel incision than in clear corneal incision for cataract surgery. In addition, intraocular pressure was found to be more stable in immediate period after scleral tunnel incision than clear corneal incision despite wound hydration is not performed in scleral tunnel incision.1 However, in case of trauma, scleral tunnel integrity may be disrupted in late period after cataract surgery and serious ocular complications may occur. In literature, scleral tunnel rupture following trauma five years after manual small incision cataract surgery with subconjunctival IOL dislocation through the tunnel was reported. 2 We describe herein a case who had scleral tunnel rupture and IOL dislocation through the tunnel following ocular trauma Case Report A AB BS S T TR RA AC CT T It has been shown that scleral tunnel incision is more secure than corneal incision in terms of wound sealing in cataract surgery. After trauma, scleral tunnel integrity may be disrupted long time after cataract surgery. We report herein a 75 year-old woman, that was referred to our department of ophthalmology with loss of vision and hemorrhagic discharge in her right eye following ocular trauma in a traffic accident. The visual acuity of the right eye was light perception and slit lamp biomicroscopy revealed diffuse subconjunctival hemorrhage, chemosis and total hyphema. She had scleral tunnel rupture and intraocular lens dislocation through the tunnel following ocular trauma. She had undergone cataract surgery and intraocular lens implantation by mini-nucleus technique 12 years ago.K Ke ey yw wo or rd ds s: : Cataract; sclera; wounds and injuries Ö ÖZ ZE ET T Katarakt cerrahisinde, skleral tünel insizyonunun yara yeri sızdırmazlığı açısından korneal insizyondan daha güvenilir olduğu gösterilmiştir. Travmayı takiben, katarakt cerrahisinden uzun zaman sonra skleral tünel bütünlüğü bozulabilir. Biz, bu yazıda trafik kazası sonucu okü-ler travmayı takiben görme azlığı ve gözden kanlı akıntı gelmesi şikayeti ile kliniğimize başvu-ran 75 yaşındaki bir kadın hastayı bildirdik. Sağ gözde görme keskinliği ışık hissi seviyesinde idi ve biyomikroskobik muayenesinde yaygın konjunktiva altı hemoraji, kemozis ve total hifeması izlendi. Oküler travmayı takiben skleral tünel rüptürü ve skleral tünelden göz içi lens dislokasyonu mevcuttu. On iki yıl önce mini nükleus tekniğiyle katarakt cerrahisi ve göz içi lens implantasyonu yapılmıştı.A An na ah h t ta ar r K Ke e l li i m me e l le er r: : Katarakt; sklera; yaralar ve yaralanmalar
