Primary acquired nasolacrimal duct obstruction results from inflammation of unknown cause that eventually leads to fibrosis and occlusion. The nasolacrimal duct is within the medial wall of maxillary sinus and open into the nasal cavity. It may be affected by gasteroesophageal reflux disease (GERD) by the possible direct noxious effect of the refluxate on the nasal mucosal cavity surrounding of the nasolacrimal duct opening at the inferior meatous and ascending of inflammation to the mucosa of the duct may leads to chronic inflammation and fibrosis. In addition to, the GERD may induce autonomic nervous system hyperactivity resulting in hyperemia of venous plexus surrounding nasolacrimal duct leading to secondary mucosal edema of nasolacrimal duct and dacryostenosis.
原发性鼻泪管阻塞是由于不明原因的炎症引起的,最终导致纤维化和阻塞。鼻泪管位于上颌窦的内侧壁,开口于鼻腔。它可能受到胃食管反流病(GERD)的影响,反流物可能对鼻泪管开口下方的鼻黏膜腔直接产生有害影响,炎症向上蔓延至导管的黏膜可能导致慢性炎症和纤维化。此外,GERD 可能会引起自主神经系统的过度活跃,导致鼻泪管周围静脉丛充血,导致鼻泪管的继发性黏膜水肿和泪道狭窄。
