Puncta and canalicular obstruction is a common ophthalmological condition that can lead to significant morbidity and impaired tear drainage. This comprehensive analysis aims to provide an overview of the etiological factors and risk factors associated with this condition, along with a detailed examination of the anatomy of the lacrimal drainage system. Diagnostic techniques for assessing puncta and canalicular obstruction, including clinical evaluation, patient history, imaging techniques, and tear drainage tests, are discussed. Additionally, various treatment options for managing this condition are presented, including the management of specific etiological factors such as inflammation, infections, neoplastic conditions, and anatomical abnormalities. The article also addresses potential complications and provides insights into the prognosis of puncta and canalicular obstruction. By elucidating the multifaceted aspects of this condition, this comprehensive analysis aims to contribute to the understanding and management of puncta and canalicular obstruction, ultimately improving patient outcomes.
