PURPOSE To describe the incidence of canalicular closure with powered endonasal dacryocystorhinostomy (DCR) without canalicular intubation in primary acquired nasolacrimal duct obstruction (PANDO). DESIGN A single-surgeon, prospective, nonrandomized, noncomparative, interventional case series. PARTICIPANTS Consecutive patients attending a specialist(More)
The term 'functional block' is used to encompass the concept of lacrimal drainage dysfunction in the presence of anatomical patency. There is significant variability in the nomenclature, clinical and investigative criteria used in the literature to define this entity. This has led to confusion and lack of comparability of studies looking at this group. The(More)
BACKGROUND To estimate the proportion of cataract surgery performed at various visual acuity and lens opacity thresholds that would coincidentally treat early angle-closure disease, and to estimate the effect of this surgery on the incidence of primary angle-closure glaucoma. DESIGN Cross-sectional, population-based survey in Meiktila, Myanmar. (More)
The levator palpebrae superioris (LPS) muscle is the main retractor of the upper eyelid, responsible for elevating the upper eyelid and maintaining it in an open position. Sound knowledge of its anatomy and adjacent structures is essential for eyelid surgery. Work from researchers and anatomists over the years continue to enrich our understanding in the(More)
BACKGROUND To determine normal exophthalmometric values for a Sri Lankan population and investigate their demographic, physical, refractive and ocular biometric correlates. METHODS The Kandy Eye study was a population-based, cross-sectional study. By randomized cluster sampling, 1721 eligible participants, who were 40 years old and over were identified;(More)
OBJECTIVE Ostium closure after endoscopic dacryocystorhinostomy (DCR) is the commonest cause for anatomic failure. We aimed to determine the changes in size of the DCR ostium over time and investigate the correlation of ostium size and surgical outcomes. DESIGN A single surgeon, prospective, nonrandomized, noncomparative, interventional case series. (More)
PURPOSE To examine the microscopic anatomic features of lower eyelid retractors in Caucasians, specifically looking for an anatomic division of the retractors into 2 layers, as is present in the Asian eyelid. DESIGN Experimental anatomic study. PARTICIPANTS Seven Caucasian cadavers (13 lower eyelids: 7 right and 6 left). METHODS Sagittal(More)
OBJECTIVE To present our experience of early endonasal DCR (endoDCR) in the treatment of acute dacryocystitis (AD). Methods. International multicenter non-comparative retrospective study. RESULTS Eighteen patients were identified. All were treated with antibiotics prior to surgery with a median of time from referral to endoDCR surgeon to surgery of 3 days(More)
PURPOSE The role of assisted local anaesthetic (aLA) for both endoscopic and external dacryocystorhinostomy is a well-tolerated and established approach. However the tolerability of aLA is unclear with powered burrs used in powered endoscopic DCR (PEDCR). We aim to evaluate the acceptability of aLA for PEDCR. METHODS This is a prospective, interventional,(More)
