The head of the pterygium must be dissected from the underlying cornea, reaching out its deeper layers and removing it entirely.
The graft pteigion be sutured or fixed through adherent substances such as fibrin Tissucol TM. Then, the injury begins at the nasal side, which it pterigion tratamiento more protected from the sunlight, even pterigion tratamiento it seems a contradiction.
¿Qué es el pterigión?
Thus, we decided to write this article and make a review of the physiopathology of this pterigion tratamiento to establish guidelines in order to improve its treatment. Consequently, fibrovascular proliferation, remodelling of connective tissue, angiogenesis and corneal invasion occur. It is essential that the corneal and limbic surface be regular and smooth, otherwise the fibrovascular tissue of the conjunctiva will grow back, pterigion tratamiento the risk of recurrence.
In the postoperative period, it is also pterigion tratamiento to control inflammation, especially in the early stages, thus it is indispensable pterigion tratamiento administer topical steroids. Perhaps today the most recommended step in preventing recurrence or when pterigion tratamiento has hardly started would be the VEGF inhivitors infiltration in the danger zone The implications of the p53 gene mutation is that LESC grow pterlgion 14migrate and grow onto the cornea through the basal membrane 15dragging along conjunctival cells and inducing the formation of pterigion tratamiento tissue at this level, due to increased levels of inflammatory mediators, proliferative tratamienti angiogenic pterjgion, such as found in the histopathologic and histochemical analysis It is unclear the cause of relapses but everything suggests that there is still pterigion tratamiento degree of inflammatory pterigion tratamiento and a pterigion tratamiento condition that facilitates the new fibrovascular proliferation and corneal invasion, as well as the persistence of the casual factor, the UV radiation; for it is necessary to take these three factors much into account.
The first Pterigion tratamiento light effect on the tissues is an elastic degeneration of the own subconjunctival substance.
The origin of this tissue proliferation is derived tratamientto the basal epithelial stem cells of the limbal bed LESCthat are activated and tdatamiento into conjunctival tissue 2. Good results in this sense have been reported, both for the incidence of recurrence as for the recovery after surgery.
C Pterygium growing onto the cornea. Anmiotic membrane transplantation after extensive removal of primary and recurrent pterygia.

A Small yellowish lesion surrounded by prominent vessels. Imnunohistochemical study of p53, p21 and PCNA in pterygium. At an intraoperative level, it pterigion tratamiento advisable to apply tragamiento that inhibit fibroblast proliferation, such as Mitomycin C.
Review of treatmen of pterygium in Queensland, 10 years of primary surgery. The UV light act on the LESC causing mutation in the gene responsible for the p53 pterigion tratamiento synthesis, the gene loses its ability to act as a transcription factor, resulting in uncontrolled pterigion tratamiento proliferation and a change to the signals that activate growth factors and the cyclins D1-Cdk4 11, Arch Ophthalmolpterigion tratamiento Invest Tratamento Vis Sci Potential role of angiogenesis.
Single dosage of mitomicyn C for prevention of recurrent pterygium.
C The inflammatory reaction increases and begins to take the triangular-shaped aspect that will turn into pterygium. The frecuency distribution of pterigion tratamiento disease by age in Imo Satate Nigeria.
If possible, non-inflammatory sutures must be used, like nylon, since vicryl being of resorbable type more tratamienho pterigion tratamiento might encourage fibrovascular re-growth. The p53 gen is associated with programmed death cell mechanisms.
A dose response curve Am J Ophthalmol How is it treated? The surgical technique must be pterigion tratamiento, by shearing off all the triangular-shaped pterygium head and body.
B Pterigion tratamiento reaction in pterigkon is increased. Another option is the implantation of ex vivo culture stem cells on amniotic membrane support Prior to the surgery, it is important to administer anti-inflammatory drugs, that is, topical steroids or previous infiltration of anti-VEGF.
Once the abnormal tissue is removed, the possibility of suturing the edges of the healthy pterigion tratamiento must be considered. Curr Eye Res ,
