摘要
Background and Objective:Nearly 30 years have passed since limbal stem cell deficiency(LSCD)was first identified by pioneers and given clinical attention.LSCD remains a difficult disease to treat.It can potentially lead to blinding.At present,understanding of limbal stem cells(LSCs)has deepened and various treatment options for LSCD have been devised.The objective of this review is to summarize basic knowledge of LSCD and current treatment strategies.Methods:PubMed search was performed to find studies published in English on LSCs and LSCD including original reports and reviews.Literatures published from 1989 to 2022 were reviewed.Key Content and Findings:LSCs are enigmatic stem cells for which no specific marker has been discovered yet.Although LSCD is not difficult to diagnose,it is still challenging to treat.An important advancement in the treatment of LSCD is the provision of guidelines for selecting systematic surgical treatment according to the patient’s condition.It is also encouraging that stem cell technologies are being actively investigated for their potential usefulness in the treatment of LSCD.Conclusions:Although various treatment options for LSCD have been developed,it should be kept in mind that the best chance of treatment for LSCD is in the early stage of the disease.Every effort should be made to preserve as many LSCs as possible in the early treatment of LSCD.
