With a "strange" eye disease, the female student's eyesight is decreasing, she has to use special lights to recognize the handwriting in the book and gradually can no longer see anyone clearly.

Ngoc Diem is a 3rd year student at a university in Ho Chi Minh City. From her secondary school days, Diem was conjectured to have signs of cataracts. The girl herself also noticed strange signs from an early age, and her eyesight gradually decreased over time. Because her eyes have an innate "veil", Diem is often noticed by people around her.



When she went to university, because she chose to major in Chinese Language, Diem had to work very hard to keep up with her knowledge. Her family bought her a special lamp to make studying easier. However, every time she studied, she had to hold the lamp close to the book to observe the handwriting.


It became more and more difficult to see by the day, to the point that even the hand in front of the eyes could not see clearly. "Every day, I find it harder and harder to see. Before deciding to find out where to get eye surgery, when my friends talked to me even at close range, I couldn't see clearly" - the female student said. .


At the eye specialist hospital in Ho Chi Minh City, after being examined by a team of doctors with specialized equipment, the girl was diagnosed with the disease "existence of the pupillary membrane", indicated for surgery as soon as possible. good to ensure eyesight.


Although the disease is not rare, the case of a covered pupil like Diem is quite rare, it is necessary to be examined periodically with specific equipment to avoid confusion with other diseases.


The female student's surgery went well. The patient underwent binocular surgery one week apart. After surgery, the patient recovered positively, his eyes were clear and he felt much more comfortable, there were no obstacles in learning. Currently, she is still in the period of post-surgery re-examination.


According to doctors, the existence of a pupillary membrane is a congenital disease, due to the incorrect development of the iris, creating fibrous rows (membrane) in front of the pupil, affecting the patient's vision. The initial manifestation of this pathology is blurred vision, gradually the membrane becomes thicker, which will interfere with observation.


Mydriasis accounts for 95% of eye defects in infants and 20% in adults.


The disease is more common in premature infants and has no sex difference, can occur in one or both eyes, and can vary in shape, size, configuration, and density.


In some cases, patients may have amblyopia because it is not detected early. The disease can be confused with secondary iris disease (AIM), congenital idiopathic iridocyclitis…


Most people have a pupillary membrane that does not affect health. In cases where there exists a thick pupillary membrane, which has a serious impact on vision, it is necessary to intervene and handle early. Depending on the specific condition, it can be treated with a laser membrane ablation procedure or a myotomy.


If the pupillary membrane adheres to the anterior surface of the lens, affecting cataracts, additional vitreous surgery should be combined.
