Title:The Kissing Puncta: an underreported cause of epiphora and presentation of a three-pronged approach to improving tear clearance
Abstract Body:
Purpose: ‘Kissing puncta’ (KP) or punctal apposition is an
anatomical phenomenon that is sparsely reported as a cause of epiphora in the
ophthalmic literature. We review our three-pronged approach to managing the
three distinct components implicated in contributing to chronic epiphora in
patients with medial canthal crowding.
Study Design: A prospective review of seven patients (fourteen
eyes) with KP associated with epiphora was conducted.
Methods: Each patient’s presenting symptoms, eye examination, and
surgical outcomes were collected. Pre- and post-intervention photos were
collected with patient’s consent. An epiphora symptom questionnaire (MUNK
scale) was completed at the time of initial consult and at post-operative
follow-up visits.
Results: Seven patients aged with average age 74 years (+3.5)
were reviewed. Megalocaruncle, medial orbital fat prolapse, and involutional
eyelid laxity were noted to be common clinical features. Punctal narrowing was
observed in four patients. All patients were free to nasolacrimal duct
irrigation with a hard stop and absence of any strictures on lacrimal probing.
Seven patients underwent our three-pronged approach to restore the medial
canthal architecture. A combined carunculectomy, medial elliptical skin incision
with transcutaneous orbital fat decompression and lateral tarsal strip
procedure was performed to successfully alleviate punctal apposition.
Additionally, four patients underwent puntoplasty as an adjunctive procedure
for punctal narrowing. At three month follow-up, all patients reported
improvement in their symptoms as denoted by a median MUNK score of 0 (median
pre-intervention MUNK score of 4).
Conclusions: Our study illustrates the significance of a thorough
medial canthal exam as an essential part of the workup and management of
epiphora. Kissing puncta can cause poor tear propagation along the eyelid
margin due to medial canthal crowing and mechanical obstruction of the upper
and lower puncta during the entire blink cycle. Restoration of normal punctal
position with our three-pronged approach conferred significant clinical
improvement in epiphora.
