Incomplete punctal canalisation: the external and internal punctal membranes. Outcomes of membranotomy and adjunctive procedures

摘要: Aims To study the clinical and diagnostic profile of punctal dysgenesis with membranes, to classify correlate membranes clinicopathologically outcomes membranotomy. Methods A prospective interventional involving 55 dysgenetic puncta 22 consecutive patients seen between July 2008 ansd December 2011. Data collected include demographics, presentation, laterality, age at duration symptoms, slit lamp examination, profiles, types associated lacrimal anomalies, management outcomes. All underwent membranotomy, after which were assessed for adequacy opening, canaliculi probes irrigation was done assess patency system. minimal follow-up 6 months taken final analysis. Primary outcome measures included anatomical on relief from epiphora subjectively also objectively by a dye disappearance test. Results The 11 males females, mean 82.4 months (range 5–264 months) presentation. Bilateral involvement in 59% (13/22) all four affected 31.8% (7/22) patients. Epiphora most common complaint noted 95% (21/22), symptoms noticed since birth 68.1% (15/22). External over 86.4% (19/22) internal 13.6% (3/22) however additional procedures like probing (3/22), mini-monoka intubation 9.1% (2/22), Crawford9s bicanalicular (2/22) dacryocystorhinostomy 4.5% (1/22). Uniformly, histopathological examination fibrovascular membranes. 100% 91% (20/22) Conclusions  This presents largest series date (n=55 puncta) exclusively and, first time, has shown clinicopathological correlation these Incomplete canalisation is probably better term this could be starting point further exploration into etiopathogenesis genetics intriguing congenital disorder.
