PURPOSE: To describe the clinical presentation and management of late (>3.0 years) acute graft rejection in keratolimbal allograft (KLAL) recipients. METHODS: This was a multicenter, retrospective observational case series. Six eyes of 6 patients with ocular surface transplant at a mean age of 36.2 years were seen at 3 tertiary referral centers for acute graft rejection between 2007 and 2013. Main outcome measures included strength of systemic immunosuppression (SI) at the time of rejection, time to rejection, and clinical presentation of rejection...

A 33-year-old woman with congenital aniridia presented with decreased vision in her right eye. Slit lamp examination revealed diffuse conjunctivalisation of the ocular surface with mild subepithelial fibrosis consistent with aniridic keratopathy secondary to limbal stem cell deficiency. She underwent limbal stem cell transplantation with cadaver donor tissue (keratolimbal allograft (KLAL) surgery) and received systemic immunosuppression. Despite optimal combination immunosuppressive therapy managed by a renal transplant specialist, 2 weeks after the KLAL, the patient developed intractable eye pain, conjunctival injection, dilation of the KLAL graft blood vessels and limbal haemorrhages...

Limbal stem cell deficiency (LSCD) is an eye disorder in which the stem cells responsible for forming the surface skin of the cornea are destroyed by disease. This results in pain, loss of vision, and a cosmetically unpleasant appearance. Many new treatments, including stem cell therapies, are emerging for the treatment of this condition, but assessment of these new technologies is severely hampered by the lack of biomarkers for this disease or validated tools for assessing its severity. The aims of this study were to design and test the reliability of a tool for grading LSCD, to define a set of core outcome measures for use in evaluating treatments for this condition, and to demonstrate their utility...

PURPOSE: To describe the incidence, characteristics, risk factors, treatment, and outcomes of ocular surface stem cell transplantation (OSST) rejection. METHODS: A chart review of patients who had OSST at a single institution between 1998 and 2010 was performed. Data were collected on patient demographics, type of OSST procedure, duration of immunosuppression, and rejection characteristics. Main outcome measures were ocular surface stability and improvement in best-corrected visual acuity...

PURPOSE: To clinically and molecularly characterize a group of patients with progressive limbal stem cell deficiency (LSCD) due to aniridic keratopathy (AK), but with minimally affected irides. DESIGN: Retrospective case series. PARTICIPANTS: A total of 12 eyes of 6 patients who underwent keratolimbal allograft (KLAL) for AK in the absence of the classic stigmata of aniridia at the Cincinnati Eye Institute/University of Cincinnati between 2000 and 2007...

PURPOSE: To report the efficacy of simultaneous keratolimbal allograft (KLAL) surgery and deep anterior lamellar keratoplasty (DALK) for limbal stem cell deficiency (LSCD). METHODS: We conducted a retrospective, interventional case series of six consecutive eyes of five patients with LSCD and stromal opacity due to gelatinous drop-like dystrophy (two eyes), Stevens-Johnson syndrome (SJS, two eyes), or aniridia (two eyes). Only patients with normal lid anatomy and Schirmer test values greater than 3 mm were enrolled...

OBJECTIVE: To determine, using objective measures, the outcome of ex vivo cultured limbal epithelial stem cell (LESC) transplantation performed in compliance with good manufacturing practice using a novel culture system without 3T3 feeder cells. DESIGN: Prospective, noncomparative, interventional case series. PARTICIPANTS: Ten eyes of 10 patients with profound LESC deficiency arising from chemical injury (4 eyes), aniridia (3 eyes), ectodermal dysplasia (1 eye), Reiger's anomaly with Pax6 haploinsufficiency (1 eye), and unknown cause (1 eye)...

PURPOSE: To develop a device that facilitates the procurement of corneal limbal stem cell grafts for keratolimbal allograft procedures used in the treatment of ocular surface disease associated with stem cell deficiency. DESIGN: Description of device design and technique for use. METHODS: The device is composed of a pedestal with a convex surface mounted to a flat platform. A corneoscleral button placed endothelial side down and centrally upon the convexity is secured by suction conveyed through a hollowed core in the pedestal that connects to fenestrated openings on the convex surface...

OBJECTIVE: Aniridic keratopathy is a major cause of vision loss in patients with aniridia. Penetrating keratoplasty has been proven ineffective for the long-term treatment of this disorder because it does not address the stem cell deficiency that is the primary etiologic factor. We evaluated the role of keratolimbal allograft (KLAL), a stem cell transplantation technique, for the treatment of patients with aniridic keratopathy. DESIGN: Retrospective noncomparative interventional case series...

PURPOSE: To evaluate the long-term outcome of ocular surface reconstruction, including keratolimbal allograft (KLAL) and amniotic membrane transplantation (AMT) with or without penetrating keratoplasty (PKP), in patients with nonambulatory vision secondary to total limbal stem cell deficiency (LSCD). DESIGN: Retrospective, non-comparative interventional case series. PARTICIPANTS: Thirty-nine eyes in 31 consecutive patients with total LSCD, as defined by impression cytology, who had a preoperative best-corrected visual acuity of less than 20/200 and a minimum follow-up of 12 months...

PURPOSE: Successful limbal allotransplantation allows regression of limbal stem cell deficiency features. Transplant survival is presumed if clinical improvement occurs. However, positive proof of surviving transplanted stem cells remains difficult. This follow-up study attempted to prove donor cell survival 5 years after limbal stem cell allograft in one woman with aniridia. METHODS: Impression cytology and single-cell DNA fingerprinting were used to investigate a previously studied patient...

OBJECTIVE: To examine whether amniotic membrane transplantation (AMT), in preparing the perilimbal stroma, enhances the success of allograft limbal transplantation (ALT). METHODS: Thirty-one eyes of 26 consecutive patients had cytologically proven limbal deficiency resulting from chemical burns (14 eyes); Stevens-Johnson syndrome, toxic epidermal necrolysis, or pseudopemphigoid (5 eyes); contact lens-induced keratopathy (3 eyes); aniridia (3 eyes); multiple surgical procedures (2 eyes); atopy (2 eyes); or an unknown cause (2 eyes)...

BACKGROUND: Limbal transplantation is a surgical technique of ocular surface epithelial transplantation advocated for a variety of ocular surface disorders with presumed stem-cell deficiency. Limbal transplantation was performed in 18 patients with ocular surface disease, which included aniridia keratopathy, chronic contact lens-associated epitheliopathy, chemical injury, Stevens-Johnson syndrome, and corneal intraepithelial dysplasia. METHODS: Limbal allograft transplantation was performed in nine eyes with the use of heterologous limbal tissue from cadaveric donor eyes or live relatives, whereas nine eyes underwent conventional limbal autograft transplantation...
