[Post-traumatic dehiscence after corneal graft at the Ophthalmology Clinic of Aristide Le Dantec Hospital in Dakar]. / Déhiscence post-traumatisme sur greffe de cornée à la Clinique Ophtalmologique de l'Hôpital Aristide Le Dantec Dakar.

Post-traumatic dehiscence is a rare condition often compromising the visual outcome of transplanted patients. It can occur after transfixing keratoplasty even after low-energy trauma. We here report two cases of patients with a history of keratoplasty, admitted to the hospital with painful red eye due to trauma. Patients' assessment objected decrease in visual acuity, subtotal graft displacement and major ocular hypotonia. After symptomatic medical treatment, they underwent surgical repair after 16 hours and 72 hours respectively. Visual prognosis was better in patient 2, who reported proper visual acuity. In patient 1 visual acuity didn't improve due to the severity of graft damage and the associated retinal detachment. The purpose of this study was to highlight the poor outcome of patients with ocular trauma after corneal graft. Prognosis was determined by survival, feasibility of grafting and the presence of associated lesions. Education, information and communication campaigns to raise awareness of this condition, especially among young patients, is the best way of preventing it.
