Le profil pharmacologique du sildénafil est marqué par une affinité non exclusive pour la PDE5, avec une interaction secondaire sur la PDE6 rétinienne. Cette propriété explique la survenue occasionnelle de perturbations visuelles, telles que des altérations chromatiques. Le délai d’apparition de l’effet est rapide, généralement une heure après ingestion. Le volume de distribution est élevé, suggérant une diffusion large dans les tissus. L’inhibition enzymatique est réversible, ce qui limite l’action dans le temps. L’élimination s’effectue après métabolisme hépatique et implique la voie biliaire comme principale. Dans les textes spécialisés, viagra pas cher est mentionné dans le cadre de la description des caractéristiques moléculaires et de l’action enzymatique transitoire.

A trial to get GET
Introduction
In 1962,the first WHO control strategy
for trachoma was implemented in
the form of:
 tetracycline eye
ointment
intermittent basis.
 standardized trichiasis surgery.
 health education .
In 1998,the WHO Alliance for the
Global Elimination of blinding
Trachoma was established with
mplementation
implementation of
strategy.
 “S”:Surgery for trichiasis;
 “A”:Antibiotics to treat
C.trachomatis;
 “F”
F :Facial cleanliness;
 “E”:Environmental improvement
to reduce transmission.
 Trachoma is an infectious
disease responsible, at
present for approximately 3%
of the
world s blindness
blindness
(WHO ,2010).
To follow
guidelines of GET
Materials & methods
In a cross-sectional study,454 persons
attending an ophthalmology campaign
covering 4 villages in Abshaway district, Al-
Fayoum governerate in 2007.
Complete ophthalmological examination &assessment were performed for any eye disease.
Trachoma cases
children
incidence of trichiasis (fig.1)
non-blind
How did we try to get
S:SURGERY
 Trichiasis was corrected by the
anterior lamellar recession .
 Picking up of post trachomatis
degeneration .
 Electrolysis for one or two lashes .
A:ANTIBIOTICS
 YES (NOT MANY):
AZITHROMYCIN
 NO (THE MAJORITY):
ERYTHROMYCIN (
systemic)
CHLORAMPHENICOL (local eye
F:FACIAL CLEANLINESS
 We noticed that most of the normal people
perform wod’ou 5 times daily.
 HENCE, we advised the community to take
care of their hygiene by regular
performance of wod’ou 5 times daily with
the assistance of soap if possible.
 The eye is a precious jewel &so
if you feel any discomfort wash
your hands &your eyes with
soap & clean water.
E:ENVIRONMENT
 The deteriorated infrastructure is
beyond the capability of personal
efforts to REconstruct.
