OBJECTIVE To report the use of preserved amniotic membrane and living related corneal limbal/conjunctival transplantation in total limbal stem cell and conjunctival deficiency secondary to severe Stevens-Johnson syndrome. DESIGN Prospective, noncomparative, interventional case series. PATIENTS AND METHODS Ten eyes of 10 patients with total limbal stem cell and conjunctival deficiency second...

The most difficult part in ocular surface reconstruction for total limbal stem cell deficiency is restoring a healthy and stable corneal epithelium. Recently, there has been a shift toward a cellular-based transplantation that eliminates the need for harvesting large amounts of limbal tissues from a living donor. The autologous oral epithelium can be used as a source for ocular surface reconstr...

The potential cause of blindness worldwide includes diseases of the cornea, ocular surface (limbal stem cell deficiency, allergic conjunctivitis, dry eye diseases), and retinal diseases. The presence of stem cells (limbal stem cells) in the basal region of the limbus makes it an important tool for the ocular regeneration and also in maintaining the transparency of eye by replacing the corneal e...

BACKGROUND & OBJECTIVES Sources of autologous tissue that can functionally replace the corneal epithelium have been considered as an alternative to allogenous limbal transplants for limbal stem cells deficiency (LSCD). The aim of the present study was to compare the characterization of oral mucosa with limbal epithelial cells by markers using reverse transcriptase polymerase chain reaction (RT-...

PURPOSE To investigate the etiology of corneal dysfunction in the Pax6(+/-) mouse model of aniridia-related keratopathy. METHODS Mosaic patterns of X-gal staining were compared in the corneal and limbal epithelia of female Pax6(+/-) and Pax6(+/+) littermates, age 3 to 28 weeks, hemizygous for an X-linked LacZ transgene, and Pax6(+/+), LacZ(-)<-->Pax6(+/+), LacZ(+) and Pax6(+/+), LacZ(-)<-->Pa...

By Eric D. DonnEnfElD, MD Astigmatic management is the step that most often keeps patients from achieving optimal visual quality after refractive cataract surgery. Residual astigmatism of 0.50 D and sometimes less may result in glare, symptomatic blur, ghosting, and halos. A recent study of 4,540 eyes of 2,415 patients showed that corneal astigmatism was present in the majority of patients unde...

purpose: to evaluate the results of one 60-degree block conjunctival limbal autograft (clau) surgery in patients with unilateral total limbal stem cell deficiency (lscd). methods: five eyes of 5 patients were included. all patients had a history of chronic total unilateral lscd due to a chemical injury. two patients underwent one 60-degree block clau with amniotic membrane transplantation, two ...

AIM To present a novel, minimally invasive strabismus surgery (MISS) technique for rectus muscle operations. METHODS In this prospective study with a non-concurrent, retrospective comparison group, the first 20 consecutive patients treated with MISS were matched by age, diagnosis and muscles operated on, with 20 patients with a limbal opening operated on by the same surgeon at Kantonsspital, ...
