Popis: Purpose: To evaluate the association between meibomian gland dysfunction (MGD) and primary chronic dacryocystitis (PCD) and the effect of dacryocystorhinostomy (DCR) on tear film stability and MGD. Methods: This prospective, interventional, non-randomized study involved 50 unilateral acquired PCD cases and 50 age-matched healthy controls. Patients with lid abnormalities, ocular trauma, previous ocular surgery, contact lens wearers, and chronic topical or systemic drug users were excluded from the study. After a detailed history, the ocular surface disease index (OSDI) was calculated. The ocular assessment included visual acuity, tear meniscus height (TMH), tear break-up time (TBUT), tear well diameter (TWD), Schirmer 1 test, meibomian gland (MG) expressibility, and meibography. PCD eyes underwent external DCR, and the tests were repeated after 8 weeks. Results: The mean age of PCD cases was 42.58 ± 12.74 years, the male: female ratio was 7:19, and the mean duration of epiphora was 2.2 ± 1 years. The MG expressibility grade of ≥2 was seen in 98% (49/50) PCD eyes, which was strongly associated with PCD as compared to controls (OR = 563, P = 0.00, 95% CI = 60.71–5229.70). MG loss ≥50% was seen in 62% (31/50) of PCD eyes and none of the control eyes. Following DCR, MG loss remained unchanged, and a significant decrease occurred in OSDI scores, TWD and Schirmer 1 values, and MG expressibility grade (Z = −6.85). The mean TMH decreased from 767.60 ± 331.60 μm to 384 ± 204.29 μm (P = 0.004) post DCR. Conclusions: PCD is strongly associated with MGD. DCR reverses the functional MG changes with improvement in the tear film stability but no effect on MG loss.
