Aim eye implant stem cells in Cuba


In careful clinical trial, ophthalmologists and hematologists tuneros open new possibilities for blind and visually.

Six weeks after its launch, with the scientific rigor that distinguishes clinical trials in Cuban medicine, stem cell transplantation as therapy against degenerative diseases of the retina is unveiling the promising future that the procedure can have on the country, for health and quality of life in blind and sighted.

Performed for the first time in the center of the eye Doctor Ernesto Guevara Hospital, in this city, the implant has been based on the search and processing of specialized information, project work, creating conditions and execution walk games, by a multidisciplinary team and cohesively integrated solid knowledge and expertise five ophthalmologists two hematologists and technicians both specialties, led by Dr. Rosa Maria Perez Guerrero Sciences and Dr. Rogelio Pérez Rivero.

Based on careful laboratory work, scholars have used plasma from the first four patients treated, in order to obtain crucial to restore damaged areas after using intravitreal implant, subtenon, retrobulbar injections and intravenous stem cells.

Cuba is well inserted in the international scientific endeavor that aims to expand and further strengthen the benign use of stem cells in ophthalmology, specifically against degenerative diseases of the retina.

As he explains Dr. Rosa Maria Perez Sciences, one of the implanted patients, visual acuity improved significantly, rising two lines of the Snellen chart; a second case advanced a line, while the fourth shows the implanted positive change in the visual field.

The study takes into account the incidence of retinitis pigmentosa and macular degeneration related to age (AMD): causes more lead to blindness and low vision in Las Tunas, according to studies of ancient Retinitis Pigmentosa Center, now part of the Guevara ophthalmology center hospital.

To start this experience has been instrumental use Filgrastim or LeukoCIM: drug produced in Cuba, whose properties include stimulating proliferation and passage of stem cells from the bone marrow into the peripheral blood stream and allows for obtaining subsequent implant for the donor.

Speaking to the correspondent of the National Information Agency in Las Tunas Dr. Porfirio Hernandez Ramirez, national coordinator of Regenerative Medicine, praised the medical and clinical human value, first test with those characteristics which there is reference here.

Although the studio is in early stage, specialists from other institutions in the country, and even abroad, show interest in details, assimilate knowledge and gradually implement them.

This clinical trial is one more step in the recognition of the seed left by the eminent ophthalmologist and scientist Pelaez, whose contribution to the study and surgical treatment of retinitis pigmentosa marked scale pattern of global medical science.
