Purpose
To show that the marvelous effect of using auto graft limbal stem cell and amniotic membrane and auto serum eye drops to reach clear cornea post sever chemical burn without the need to do keratoplasty but to reach this point we need long time
Setting
the memorial institute for ophthalmic research
Report of case
patient came complaining of drop of vision in the RT eye post chemical injury 6 m. ago . Examination showed that complete conjunctivalization of cornea due to destruction of all stem cells in this eye , symblepharon , closed fornices , the vision was HM and u/s showed retina in place . I decided to do limbal stem cell transplantation from other eye then wait until have good limbal stem cells in this eye then do keratoplasty. In operation , I excised adhesions and fibrous tissue on the surface of the cornea , prepare the stem cells from other eye , suturing them at sides of the cornea at zero and 180 degree then fashion a large layer of the fresh amniotic membrane that cover the cornea and large area of sclera and suture amniotic to the sclera , then suture residual parts of conjunctiva above the amniotic (shown in video) . start treatment with prepared auto serum eye drops from the next day for at least 2 months .after 3 months the vascularization of the cornea disappear and cornea became more clear and the vision improve to 6/60 and it is irrefractable . after 6 months , the cornea became more clear with the vision improved to 6/24 by -1.0 x -4.50 @140 and fundus examination showed retina in place with disc cupping 0.4 and ORA showed corrected iop 28 so I started to give 1 antiglaucoma eyedrop . after 1 year , the cornea became almost clear with BCVA 6/12 by plano/-2.5@140 and iop controlled by medical TTT , the pentacam showed the thinnest location was 360 um .
Conclusion/Take home message
Chemical burn to the eye usually have a very poor prognosis
Limbal stem cell transplantation is the only hope for those patient who have massive destruction of their original stem cells
Use the amniotic membranes and auto serum eyedrops help the healing of these cases and some times give unexpected marvelous results that the corneas become almost clear and we donot need to do keratoplasty but this need long time
