Giant corneal keloid following Descemet stripping automated endothelial keratoplasty for the treatment of corneal decompensation secondary to trauma.

Purpose: This report aims to present a case of corneal keloid caused by chronic corneal insult after trauma and Descemet stripping automated endothelial keratoplasty (DSAEK).

Case Presentation: A 35-year-old male with a history of vision loss in the right eye was referred to our hospital. The patient underwent Ahmed Glaucoma Valve Implantation to alleviate elevated intraocular pressure after ocular trauma to the same eye. One year following the procedure, the eye developed endothelial failure, leading to the performance of Descemet's Stripping Automated Endothelial Keratoplasty (DSAEK) with repositioning of the shunt tube. Upon initial examination, a well-circumscribed elevated white opaque lesion involving the central corneal surface of the RE was observed. Based on the patient's clinical history, slit lamp examination, and UBM findings, the diagnosis of corneal keloid was established. Superficial keratectomy was performed. Histopathological analysis confirmed the diagnosis of corneal keloid. Following the procedure, BCVA improved slightly. However, 3 months later, the patient underwent a penetrating keratoplasty for visual rehabilitation.

Conclusion: Corneal keloids should be considered following any form of ocular trauma, particularly in cases involving ocular surgery. Diagnosing corneal keloids can sometimes be challenging due to the variety of potential differentials; however, by carefully evaluating the patient's medical history and clinical presentation, we can effectively narrow down the differential diagnosis of corneal conditions.
