Long term follow-up (12 - 26 Years) and Permament Fistula
Formation in Conjunctivo - DCR with Pyrex Glass Tubes
Gupta Ved (1)
1. University College of Medical Sciences and G.T.B.Hospital
Objective and Purpose: To report long term follow – up (12 – 26 years) and
permanent fistula formation in conjunctivo – DCR with pyrex glass tubes.
Methods:105 eyes underwent modified technique of
conjunctivodacryocystorhinostomy using internal fixation suture to secure
pyrex glass tube for treatment of epiphora resulting from canalicular obstruction
during 1985 to 2010.
Results: There were 74 (70.48%) females and thirty one (29.52%) males. The
age ranged from 15 to 65 years. The etiology of canalicular obstruction
included, trauma, congenital abnormalities, conjunctival inflammation, Bell’s
palsy, repeatedly failed DCR, resection of basal cell carcinoma and idiopathic.
None of the cases developed extrusion. Undue lateral projection of tube
occurred in 7 cases (6.6%). Follow-up period in 10 patients ranged from 12
years to 26 years. Permanent fistula formed at caruncle area in 7 of these
patients after removal of tube with relief of epiphora, patent syringing through
fistula, normal tear meniscus height and dye disappearance test. Fistula has
not closed after 7–12 years follow–up. 3 patients are still retaining the tube
after 20, 21 and 26 years postoperatively without any epiphora or any major
complications.
Conclusion: Excellent uneventful retention of tubes is attributed to internal
fixation suture to secure the tube.

Anatomical Utility of Ultrasound Biomicroscopy in the Lacrimal
Drainage System
Al-Faky Yasser (1)
1. Ophthalmology Department, College of Medicine, King Saud University
Purpose: To evaluate lacrimal drianage system (LDS) in normal individuals and
in different pathological conditions using ultrasound biomicroscopy (UBM).
Methods: UBM evaluation was carried out using a modified technique utilizing
swimming goggles with removal of the eye-pieces as an adjunctive device to
overcome the difficulties of UBM evaluation of LDS.
Results: A total of 24 normal LDS were evaluated in 12 volunteers with an age
range of 14 to 54 years (mean 31.17±14.09 SD). The lacrimal sac (LS)
longitudinal diameter was always greater than the screen limits (?15 mm) and
the width varied from 1.87mm to 3.36mm (mean 2.56±0.43 SD). Horizontal
scanning of LS revealed mean cross sectional area of 5.74mm2 ±2.61mm2
SD. The cross-section diameter of the canaliculi varied from 0.52mm to
0.88mm. LDS was also evaluated with UBM for the following disorders:
chronic dacryocystitis, LS fistula, mucocele, dacryolith, LDS with silicon
tube, congenital and acquired canalicular obstruction, punctal plugs, Down’s
syndrome, and Sjögren syndrome after permanent punctal occlusion.
Conclusions: UBM is a valuable tool in the assessment of both normal and
diseased LDS. It is a valuable tool in the evaluation of LDS distal to the site of
complete obstruction.

Tertiary Eye Care Centre

1. Aravind Eye Hospital
Objectives: To study the clinical profile and outcome of dacryocystorhynostomy
in paediatric population.
Methods: Retrospective analysis of outcome of External Dacryocystorhinostomy
in 57 cases of paediatric lacrimal drainage system obstruction.
Results: The mean age is 8.9 years with males more commonly affected. 32
cases were unresolved CNLDO with CDC. Other surgical indications included
lacrimal fistula, post-traumatic, previous failed DCR. 44 patients underwent
external DCR, 9 underwent external DCR with intubation; 1 underwent
canalicular DCR with Jones› tube; 3 underwent external DCR with fistulectomy.
At first follow-up 55 (96%) patients achieved complete cure and 2 (4%) patients
had to undergo repeat DCR.
Conclusion: External DCR has excellent outcome in CNLDO with CDC with
high success rate. External DCR with intubation in previous failed DCR or
SNLDO has favourable outcome with over 80% success rate.

The Dacrycystorhinostomy and Normalization Time of Conjunctival
Flora

1. Tehran University of Medical Sciences, Farabi Eye Hospital
Purpose: To identify the time of normalization of conjunctival flora after DCR.
Methods: 119 adult patients with lacrimal duct problems were included for this
study; they were divided into four groups; NLDO with pus discharge, NLDO
without pus discharge, NLD stenosis and canalicular obstruction. The first
two groups were treated by DCR surgery and when it was necessary, silicon
tube was used. Before surgery conjunctival specimens were obtained from
the involved side and normal side. Post operatively, conjunctival sampling was
continued weekly until the result of the culture became negative.
Results: The mean time of normalization was 4.4 weeks for NLDO with pus and
3.2 weeks for NLDO without pus. The time of normalization was significantly
related to the type of organisms (P
