Question
What causes pediatric glaucoma?
Answer
The main causes of glaucoma include overexertion, insufficient sleep, emotional fluctuations, poor diet, or overeating, which can affect the vascular nerve regulatory center and lead to dysfunction in vascular contraction and relaxation. On one hand, it can cause the dilation of capillaries and increased vascular permeability, resulting in the swelling and forward movement of the ciliary muscle, blocking the anterior chamber angle, and obstructing the outflow channel of aqueous humor. On the other hand, it can lead to excessive secretion of aqueous humor, resulting in high posterior chamber pressure. This pressure pushes the peripheral iris forward, causing the anterior chamber to become shallow and the anterior chamber angle to narrow. These factors can all cause a sharp increase in intraocular pressure, eventually leading to an acute attack of glaucoma.
