Purpose. To compare the long-term clinical outcomes of cultivated limbal epithelial transplantation (CLET) in children and adults
with limbal stem cell defciency. Design. Retrospective case series. Methods. Case records of patients with limbal stem cell defciency
(LSCD) who underwent CLET from April 2004 to December 2014 were studied. Outcome measures were compared in terms of
anatomical success and visual improvement. Parameters for total anatomical success were avascular, epithelized, and clinically stable
corneal surface without conjunctivalization, whereas partial anatomical success was considered when mild vascularization (sparing
centre of cornea) and mild conjunctivalization were noted along with complete epithelization. Results. A total of 62 cases underwent
the CLET procedure: 38 (61.3%) were children and 24 (38.7%) were adults. Patients with unilateral LSCD (33 children and 21 adults)
had autografs and those with bilateral LSCD (5 children and 3 adults) had allografs. Amongst the 54 autografs partial and total
anatomical success were noted in 21.2% and 66.6% children, respectively, and 19.0% and 80.9% in adults, respectively ( value 0.23).
Visual improvement of 1 line and ≥2 lines was seen in 57.5% and 21.2% children, respectively, and 38% and 38% in adults, respectively
( value 0.31). Conclusion. Cultivated limbal epithelial transplantation gives good long-term results in patients with LSCD and the
outcomes are comparable in children and adults.
1. Introduction
Te cornea is the most important part of ocular surface
which provides eye with two-thirds of its focusing power and
protection of ocular integrity and helps in maintaining clear
and useful vision due to its transparent and avascular nature
[1]. Corneal stem cells play important anti-infammatory as
well as antiangiogenic roles in maintaining a normal corneal
microenvironment and destruction of which leads to limbal
stem cell defciency [2]. Two major associations of primary
limbal stem cell defciency are aniridia and ectodermal dys-
plasia. For secondary or acquired limbal stem cells defciency
physical, chemical, thermal, and immunological insults are
the major factors out of which chemical injuries contribute
the maximum [3].
A number of therapeutic strategies for the treatment of
LSCD have been documented in the past, but the decision
for choosing a particular treatment modality depends solely
on the severity and laterality of defciency [4, 5]. In limbal
stem cell defciency as well as in other ocular pathologies, the
ocular infammatory response to any kind of insult is always
expected to be more in the paediatric age group [6]. In most of
the published literature the success rates of CLET have been
documented in adult patients, except one study where the
surgical outcomes of CLET were reported in paediatric age
group only [7]. The present study was hence undertaken to
compare the long-term results of cultivated limbal epithelial
transplant in children versus adult patients, which has not
been documented yet.
