At present, installation of punctal plugs (tear duct occluders) draws attention of ophthalmologists, but this method of treating dry eye syndrome (DES) is not without complications. Considering the rise of DES occurrence — the tendency anticipated to continue — as well as expansion of indications for installation of tear duct occluders, their usage can be expected to rise. The article describes a relatively rare clinical case that involved intracanalicular migration of silicone punctal plug. A female patient of 36 years old sought medical help in Research Institute of Eye Diseases (Moscow) to treat a lump in the area of lower lacrimal punctum in the left eye that was growing in size; the lump had appeared around 2 months prior to the visit. Patient’s medical history read that around 2 years ago she had a silicone occluder installed in the lower lacrimal punctum of the left eye. On examination, in the area of lower lacrimal punctum, a body with a nutrient vascular pedicle deriving from lower lacrimal duct could be found. The occluder was absent in the opening of the lacrimal punctum. A revision of lower tear duct cavity was performed to remove its contents. The body filling tear duct opening was removed with forceps. Substance was then sent for histological examination. Tear duct was scraped out, the silicone occluder removed and sent to laboratory for scanning electron microscopy. The patient had no complaints 6 months after the procedure. Conclusion. The study showed that the forming body was granuloma resulting from aseptic inflammation. Surface of the silicone occluder in retention of lacrimal pathways remained unchanged. Described surgical tactic is suitable for treating patients with intracanalicular punctal plug migration.
