Abstract
Dacryoendoscopy is the intraluminal visualization of the lacrimal drainage system using a miniature endoscope coupled to a high definition camera unit. It helps in complete visualization of the lacrimal pathway from punctum to the inferior meatus. Dacryoendoscopy has been used in a variety of indications like congenital nasolacrimal duct obstruction (CNLDO), especially in refractory cases of CNLDO, laser dacryoplasty, microdrill dacryoplasty, primary acquired nasolacrimal duct (NLD) obstruction, individual and common canalicular obstructions and in understanding the physiology of lacrimal drainage system [2, 9–17]. It however has a steep learnig curve, the scope is very delicate and fragile and expensive limiting its use in routine practice.
