Abstract
ABSTRACTCorneal endothelium is the innermost layer of the cornea which has both barrier and pump function and very important to maintain cornea clarity. Unlike epithelium, endothelium does not have regenerative potential; hence, endothelial damage or dysfunction could lead to corneal edema and visual impairment. Advanced corneal transplantation which involves selective replacement of dysfunctional endothelium has led to improved and faster visual rehabilitation. But in recent times, alternative therapies in the management of corneal edema and endothelial diseases have been reported. In this review, we aim to give a comprehensive review of various strategies for the management of corneal endothelial dysfunction in order to give treatment which is precisely tailored for each individual patient. A review of all peer-reviewed publications on novel strategies for the management of endothelial dysfunction was performed. The various approaches to the management of endothelial dysfunction are compared and discussed. Shortage of human donor corneas globally is fuelling the search for keratoplasty alternatives. Corneal endothelial dysfunction can be caused following surgery, laser or corneal endothelial dystrophies which could be amenable to treatment with pharmacological, biological intervention and reverse the endothelial dysfunction in the early stages of endothelial failure. Pharmacological and surgical intervention are helpful in cases of good peripheral endothelial cell reserve, and advanced cases of endothelial cell dysfunction can be targeted with cell culture therapies, gene therapy and artificial implant. Treatment strategies which target endothelial dysfunction, especially FECD in its early stages, and gene therapy are rapidly evolving. Therapies which delay endothelial keratoplasty also are evolving like DSO and need more studies of long-term follow-up and patient selection criteria.
