The outcome of congenital glaucoma is very much related to the timeliness of the treatment. Choosing the right surgery and performing it early in life, the vast majority of cases can be cured. Case: A 4-month-old boy presented with photophobia, did not like to open his eyes and would not look at the light. On examination, the corneas of both eyes were highly dilated, cloudy and grayish white, and the intraocular pressure was above 40 mmHg. A trabeculotomy was performed under general anesthesia. On examination two days after surgery, the child could look at the light, the IOP was normal, and the corneas were clearly clear and basically returned to normal size. Figure i: Preoperative eye enlargement with corneal clouding and difficulty in eye opening. It would not catch the light. Figure 2: Two days after surgery, the eye was well gazed, the eye was shrunken, and the cornea basically returned to clear.
