Abstract
Epiphora is the imperfect drainage of tears
through the lacrimal passilges. It is a universal symptom
of the lacrimal drainage system disorders. The balance
between tear secretion and elimination is essential
to keep an optically uniform surface of the cornea.
In addition, presence of an obstruction within the
nasolacrimal drainage system often predispose to infection
which may endanger the eye.
This study was carried out on two hundred fifty
eyes of one hundred eighty two patients complaining
of obstructive epiphora in the period from Augest
1984 to March 1988.
The diagnosis of these cases depent upon general
opthalmological examination, examination of the eye
lids and puncti, the lacrimal gland, palpation of the
medial canthal region and performing the regurge test.
Basic secretion test, Jones (1) and dye disappearance,
Jones (2) and diagnostic syringing, diagnostic probing
and nasal examination were also performed.
Bacteriological examination was performed to
one hundred thirty three eyes. Dacryocystography was
performed to eighteen ca~es, six of which preoperative
and twelve postoperative.

Patients complaining of epiphora due to lid
and nasal disorders were Hxcluded from the study.
Patients were classified into two main groups:
1- Congenital and early acquired group up to the
age of ten years of life. It included one hundred
ninty four eyes of one hundred thirty four
patients.
2- The acquired group included fourty eight patients
with fifty six eyes affected.
The treatment of our cases depent upon the age
of the patient, the site and extent of the obstruction,
previous procedure done to the patient and the nasal
condition.
In patients below three months of life, we started
with conservative treatment and massage of the lacrimal
sac up to six weeks. Failed cases were sUbjected to
probing. Patients above t.hree months up to ten years
old of life were sUbjected to probing.
In acquired cases we pprformed dacryocystectomy
for eleven eyes sUffering from chronic dacryocystitis
with gross nasal or canalicular disorders.
Thirty five dacryocystorhinostomies were performed
by three main techniques: DupUy-Dutemps, Traquair,
and Traquair with silastic intubation. Only one case
was performed by Toti technique.

Conjunctivorhinostomy was performed by a new
method utilizing a vein graft for connecting the
conjunctival sac and the nasal cavity without making
an osteal perforation in ten eyes with canalicular
obstruction or epiphora following.dacryocystectomy.
As regards our results, they were as follows:
1- Massage: Total success rate was 81.7%.
2- Probing: Total success rate was 82.8%.
3- Dacryocystectomy: Subjective improvement of
epiphora occurred in 9.1% of cases.
4- Dacryocystorhinostomy:
a- Dupuy-Dutemps technique: 81.8% objective
functional improvement.
b- Traquair technique I 72.7% objective functional
improvement.
c- Thaquir techniquo with silastic intubation:
83.3% objective functional improvement.
S- ConjunctivorhinostomYI Total success rate was
50% objective functional improvement.
