DECODING THE RELATIONSHIP BETWEEN MEIBOMIAN GLAND DYSFUNCTION AND PRIMARY CHRONIC DACRYOCYSTITIS

Abstract

Background: Meibomian gland dysfunction (MGD) is a prevalent comorbidity with PCD. In PCD, mucopurulent material
regurgitated from the lacrimal sac to the ocular surface causes tarsal and conjunctival inflammation, which predisposes to MG
damage.
Aim: The current study sought to determine the relationship between meibomian gland dysfunction and primary chronic
dacryocystitis. The study also looked at the impact of DCR dacryocystorhinostomy on MGD and tear film stability.
Methods: The study included 200 participants, 100 of whom had unilaterally acquired PCD and the remaining 100 were age-
matched healthy controls. All individuals' histories were documented, as well as the OSDI (ocular surface disease index).
Meibography, MG expressibility, Schirmer 1 test, TWD (tear wall diameter), TBUT (tear break-up time), TMH (tear meniscus
height), and visual acuity were all part of the ocular assessment. PCD ophthalmics were subjected to DCR, and tests were
repeated after 8 weeks.
