 Dacryocystitis is an infection of the lacrimal sac, secondary
to obstruction of the nasolacrimal duct at the junction of
lacrimal sac.
 The term derives from the Greek dákryon (tear), cysta (sac),
and –it is (inflammation).
 Although there are several causes, the main mechanism for
the occurrence of dacryocystitis is distal obstruction of the
nasolacrimal duct, which leads to the retention of tears
and detritus at the level of the lacrimal sac.
 Predisposing Factors.
 Factors causing stasis of tears.
 Source of infection.
 Causative organisms.
AGE:30-40 YEARS OF AGE.
GENDER:F>M.
LOW SOCIOECONOMIC STATUS.
POOR PERSONAL HYGEINE.
 Anatomical factors.
 Foreign bodies.
 Excessive lacrimation.
 Mild grade inflammation.
 Obstruction of lower end of NLD.
 GRAM POSITIVEStaphylococcus aureus and
Streptococcus pneumoniae being the most common
 Gram-negative bacteria Haemophilus influenzae,
Serratia marcescens and Pseudomonas aeruginosa
 Anaerobic microorganisms have been isolated in as many
as 15.7% of the positive cultures, in some studies, the most
common genus being Bacteroides (5.7%).
 As for fungi, they have been reported to be present in 4% to
7% of cases, the most commonly isolated genus being
Candida, although Aspergillus and Mucor may also be found

 There is intermittent conjunctival hyperaemia and
epiphora, with mucoid discharge that is normally sterile.
 Lacrimal syringing –clear fluid or few fibrinous flakes
 Dacryocystography –block in the NLD, normal sized
lacrimal sac with healthy mucosa
 Stagnant tears collect and there is dilation of
the lacrimal sac, with mucoid content.
 Dacryocystography –distended sac with
blockage in the NLD.
 Epiphora and chronic conjunctivitis are
observed, with erythema of the lacrimal sac.
 There is reflux of purulent material with
pressure, and microorganisms are often isolated.
 •Dacryocystography – very small sac with
irregular mucosal folds.

 TEAR FILM BREAK UP TIME AND
PATENCY
 JONES DYE TEST
 SYRINGING AND PROBING--ASSESS LEVEL OF OBSTRUCTION
 Technique: The anterior lacrimal crest
is identified by tracing the inferior
orbital margin medially and superiorly.
 The index finger is then directed behind
the crest and used to apply
pressure on the sac area in an upward
and medial direction so as to express
the contents of the lacrimal sac into
the conjunctiva.
 Any reflux of fluid or purulent material
from the puncta is noted.
 INDICATES patent canalicular sysem
and obstruction distal to lower end of
lacrimal sac.
 Flourescein dye injected into both conjuctval
sacs & observed for 5 minutes.
 1 drop of 2% fluorescein is instilled into the
unanaesthesised conjunctival sac of both the
eyes.
 Prolonged retention indicates obstruction to
lacrimal apparatus.
Principle : It provides information regarding the patency
of canalicular system.
Procedure :
 1-2 drops of topical anaesthesia is instilled into the
conjunctival sac.
 The punctum is dilated gently by advancing the Nettleship dilator,
first vertically for about 2mm & then horizontally with a twisting
movement.
 With the eyelid stretched, dilator is withdrawn & the Lacrimal
cannula attached with syringe filled normal saline is advanced
horizontally through punctum & canaliculus.
 Irrigation is then done & the patient is asked to respond if fluid
passes into the oropharynx or nose.
 Inference :
If there is resistance to irrigation: obstruction is partial.
Regurgitation of fluid from same punctum indicates canalicular
block.
Regurgitation of fluid from upper punctum indicates blockage at
the level of common canalicular duct, lacrimal sac or
nasolacrimal duct.
 Relatively delayed regurgitation of fluid mixed with
mucous or pus usually indicates NLD blockage
 A probe of appropriate size is inserted into the punctum, turned
medially & advanced untill it encounters the lacrimal bone.
 Obstruction can be felt as a “ Soft stop” in case of canalicular
stenosis or as a “ Hard stop” as the probe hits the bone at the
medial wall of lacrimal sac.
 PROBE USED-BOWMAN PROBE SIZE 0 OR 00.
Types : These are of 2 types :
a) Jones test I
b) Jones test II
JONES TEST 1-Drop of 2% fluoresceine is instilled into
conjunctiva.
After 5 min a cotton bud is inserted under inf.turbinate.
Positive: Fluoresceine recovered from nose indicates
patency of drainage system.
Negtive: no dye is recovered indicates partial obsruction or
pump failure
JONES TEST II-
 Also called Irrigation or secondary test.
 It is a non-physiological test.
 Principle :It identifies the probable site of partial
obstruction, on the basis of whether the fluorescein
dye instilled for primary/Jones test 1 entered the
Lacrimal sac.
 Procedure :Topical anaesthetic is instilled & any
residual fluorescein is washed out instilled during Jones
test 1.The drainage system is then irrigated with saline
with the cotton bud under inferior turbinate.
 POSITIVE:Fluorescein stained saline recovered from
the nose indicates that fluorescein entered the
lacrimal sac.
 NEGATIVE:This implies partial obstruction of puncta,
canaliculi, common canaliculi or defective lacrimal
pump mechanism.
a ) Dacryocystography:
 DCG involves injection of radio-opaque dye into
the canaliculi & taking magnified images.
 Indications of DCG :
1. To confirm the site of
obstruction,especially prior to lacrimal
surgery.
2.To aid diagnosis of diverticula, fistulae &
filling defects caused by stones & tumours
 Technique:Inferior puncta are dilated with a
Nettleship punctum dilator.
 Contrast medium, usually 1-2ml Lipiodol,0.5-2ml of
water soluble iodinated contrast medium is injected
simultaneously on both the sides & anteroposterior
radiographs are taken.
b. Nuclear Lacrimal Scintigraphy:
 Nuclear lacrimal scintigraphy is a simple, noninvasive
physiological test that evaluates patency of the
lacrimal system.
 Scintigraphy uses a radiotracer (technetium-99m
pertechnetate), which is very easily detectable with
a gamma camera.
 The disadvantage as compared to DCG is that it
fails to show finer anatomical details.
 Apart from being a non-invasive procedure,radiation
exposure to lens is minimal compared to DCG.
 It is more sensitive in assessing incomplete blocks.
MRI:-ADVANTAGES--
MRI is reserved in cases
where tumors are
suspected.
a) Chemiluminiscene test : Cyalume, a chemiluminiscent material is
injected with a sialography catheter to demonstrate the patency of
outflow passages.
b) Dacryoscopy : Dacryoscope, a mini rigid endoscope allows the direct
visualisation of the interior & lining of lacrimal passages.
c) Standardised echography :Gross anatomical structural defects can be
evaluated.
d)Thermography : It is used in conjunction with routine lacrimal irrigation to
visualise the tear ducts in normal subjects and in patients with
obstructive epiphora.assess the degree of tissue inflammation.

 Dacryocystorhinostomy (DCR) introduced by Toti in 1904 is a lacrimal
drainage operation in which a fistula is created between the lacrimal sac
and the nasal cavity in order to bypass an obstruction in the nasolacrimal
duct.
 Endonasal-DCR first described by caldwell 1893
 The first modern endoscopic endonasal DCR procedures were
described by McDonogh and Meiring in 1989.
Types: 1. EXTERNAL DCR
2. ENDONASAL/ENDOSCOPIC DCR
3. ENDOLASER DCR
 The main advantage of external DCR is visualization of the
anatomy that facilitates the precise removal of bone in the
lacrimal fossa and enables the exact anastomosis of the
nasal mucosa and lacrimal sac.
 Chronic epiphora due to a nasolacrimal duct
obstruction.
 Recurrent or chronic dacryocystitis.
 Failed probing and silicone intubations in a
child.
 Proposed intraocular surgery in the presence of
nasolacrimal duct obstruction.
Under GA;curved incision along medial to
medial canthus is givenMedial palpebral
ligament is exposed by blunt dissection to
expose anterior lacrimal crest.
Periosteum is seperated from anterior lacrimal
crest & lacrimal sac is reflected laterally with
blunt dissectorexpose nasal mucosa
Probe is introduced into sac through lower
canaliculus & sac is incised verticallyfashining of
nasal mucosa into H shaped
Suturing of flaps by 6-0 vicryl is done
Medial palpebral ligament is sutured to
periosteum;orbicularis muscle sutured
with 6-0 vicryl
 The reported success rate of this surgery ranges from 80 to 95 %, with the
major risks being wound complications (scar, infection, ectropion, or
disruption of the medial canthal ligament) and nosebleeds.
 Mean operative time is shorter in endonasal DCR than in external DCR
 Postoperative cutaneous scarring was unique to the external DCR
procedure.
 Post operative bleeding No significant difference
INDICATIONS:
 Patients with NLD obstruction and a previous history of
sinus surgery.
 Facial trauma
 Failed external DCR are good candidates for endoscopic
DCR.
 In cases of previously failed DCR, endoscopy
can help visualize previous scarring.
 Adolescents with anatomic variations from atypical forms of
congenital dacryostenosis may also benefit from endoscopic
DCR.
 Acute dacryocystitis.
 Patient is on anticoagulation medications and
is unable to stop perioperatively.
 Obstruction in the canaliculi or puncti.
 The success rates of endoscopic DCR reported in the literature
range from 79.4 to 96 %.
 Prevention of an external scar in the area of the medial
canthus.
 Preservation of the pump mechanism of the orbicularis
muscle.
 Decreased hospital stay.
 Less postoperative discomfort.
 Simultaneously can correct intranasal pathologic
conditions such as paranasal sinusitis and septal deviation
via endoscopic instrumentation.
 More rapid rehabilitation and a shorter duration of
surgery.
