NCT04680078

Brief Summary

a prospective randomized study conducted upon 40 eyes of 24 patients with lower punctual stenosis (grade 1 or 2 according to Kashkouli scale) attending at Menoufia University hospitals and Kafr Elsheikh ophthalmic eye center. The upper punctum and canaliculus were patent. All patients were complaining of epiphora and had a thorough ophthalmological examination including dye disappearance test, and slit-lamp examination. A Nettelship dilator is used to enlarge the stenotic lacrimal punctum. A single blade of a small Westcott spring scissor or Vannus scissor is placed within the ampulla of the lacrimal canaliculus, with the remaining blade placed on the conjunctival surface of the posterior aspect of the eyelid. The first vertical snip is made at the vertical canaliculus. The second vertical snip is made from the edge of the first snip to create a flap. The final horizontal snip was made at the base. The triangular flap is removed and three sutures are placed, in an interrupted manner, at the posterior wall of the ampulla using 10-0 nylon. The sutures are removed 1 week after the surgery. Topical moxifloxacin 0.5% eye drops and fluorometholone 0.1% eye drops were used four times daily for one week.Patients were then followed up for 6 months after the surgery.

Outcome Measures

Primary Outcomes (3)

  • Degree of improvement of epiphora by Munk score

    Measurement of improvement of epiphora by use of Munk score as follow : Grade 0 : No Epiphora. Grade 1 : Occasional epiphora requiring drying or dabbing less than twice a day. Grade 2 : Epiphora requiring dabbing two to four times per day. Grade 3 : Epiphora requiring dabbing five to ten times per day. Grade 4 : Epiphora requiring dabbing more than ten times daily or constant tearing.

    6 months

  • Degree of improvement of lacrimal drainage by Dye disappearance test

    Performed by putting a drop of 2% fluorescein sodium in the conjunctival sac followed by assessment after 5 minutes of the remaining dye in the tear meniscus. Results were graded according to the following scale Grade 1 : \<3 minutes Grade 2 : 3-5 minutes Grade 3 : \>5 minutes

    6 months

  • Slit lamp assesment of the state of the lower punctum

    Slit lamp examination of the lower punctum and its grading according to Kashkouli scale as follows: Grade 0 : No punctum (agenesis) Grade 1 : Papilla is covered with a membrane (difficult to recognize) Grade 2 : Less than normal size, but recognizable Grade 3 : Normal Grade 4 : Small slit (\<2 mm) Grade 5 : Large slit (≥2 mm)

    6 months

Study Arms (2)

Placement of three interrupted sutures after Triangular Three-snip Punctoplasty of the lower punctum

ACTIVE COMPARATOR

After instillation of topical benoxinate hydrochloride 0.4%, subconjunctival injection of 2% lidocaine was done beneath the lower punctum, then Nettleship dilator was used to dilate the punctum. A single blade of a small Westcott spring scissor or Vannus scissor is placed within the ampulla of the lacrimal canaliculus, with the remaining blade placed on the conjunctival surface of the posterior aspect of the eyelid. The first vertical snip is made at the vertical canaliculus. The second vertical snip is made from the edge of the first snip to create a flap. The final horizontal snip was made at the base. The triangular flap is removed and three sutures are placed, in an interrupted manner, at the posterior wall of the ampulla using 10-0 nylon. Hemostasis was done by compression with a cotton tip for one minute until bleeding stop. The sutures are removed 1 week after the surgery.
