| Summary: | Acquired external punctal stenosis (AEPS) denotes anatomical narrowing of lacrimal punctum, which clinically manifests as epiphora. AEPS may be asymptomatic in a patient with dry eye. Under conditions of normal or excessive tear production; AEPS can produce symptomatic epiphora, which is an indication for intervention. Chronic blepharitis and idiopathic stenosis are the most common etiological factors. Preventable punctal stenosis in patients on long term taxanes or 5-fluorouracil occurs due to systemic absorption of these drugs and secretion in tears. In such cases, AEPS may be prevented by prophylactic lacrimal intubation. AEPS may have associated canalicular stenosis in 45% of cases. This review deals with the etiology, clinical diagnosis and management of AEPS, which has evolved over the years from the earliest description of simple punctal dilatation to present day use of monocanalicular and bicanalicular silicone stents. |
