Question
A 34-week premature infant, born 46 days ago, has developed eye discharge and tears. The symptoms have persisted for 5 days. The infant has tried using saltwater to wipe the eyes for 2 days, with no improvement. Subsequently, Tobramycin eye drops were used for 2 days, but the symptoms have not been relieved.
Answer
Excessive eye discharge may be due to bacterial invasion of the lacrimal sac, where the bacteria reproduce and cause inflammation, leading to pus filling the entire lacrimal sac. The pus cannot be normally expelled and can only flow upwards along the lacrimal sac and lacrimal ducts into the eye. If not treated promptly, it may lead to keratitis, potentially causing white spots on the cornea and affecting vision. It is recommended to undergo a detailed examination to determine the exact cause and receive appropriate treatment as prescribed by a doctor.
