Figure 1. Schematic illustration of decompression of the lacrimal sac through probing procedure (created using Procreate app). Canalicular and NLDO causing giant lacrimal abscess before probing (A). The probe is gently inserted into the obstructed canaliculus to recanalize it, restoring the normal physiological function of the lacrimal drainage system. The syringe is used to withdraw the accumulated pus and decompress the lacrimal sac. The lower eyelid was pulled toward the temporal side and the lower canalicular cavity was straightened for easy access of the probe to the bottom of the lacrimal sac without creating a false passage (B). The probing was performed to entirely remove the blockage from the nasolacrimal duct. The pus present in the lacrimal sac was withdrawn into the syringe during this step (C). Appearance after decompression and probing (D).
