Your task is to create a single paragraph that summarizes the key points from three provided paragraphs. When you incorporate information from each paragraph, cite that information using these references: 1 for the first paragraph, 2 for the second paragraph, and 3 for the third paragraph, which means you should only use these three references. 

Here are the paragraphs:

1. Glaucoma represents a variety of eye disorders characterized by chronic and progressive damage to the optic nerve. The key modifiable risk factor is increased intraocular pressure (IOP), contributing to disease progression. For the past 25 years, treatment methods have primarily consisted of medication and surgical interventions. However, Minimally Invasive Glaucoma Surgery (MIGS) has shown promise in offering consistent IOP reduction while minimizing glaucoma intervention risks and reducing reliance on glaucoma medication.

2. Glaucoma, a prevalent eye condition, involves damage to the optic nerve connecting the eye and brain, often caused by fluid build-up in the eye's anterior part, which elevates eye pressure. If not diagnosed and treated early, glaucoma can result in vision loss. It can affect individuals of all age groups but is more common in adults in their 70s and 80s.

3. Glaucoma encompasses a series of eye diseases that can lead to vision loss and blindness by harming the optic nerve at the back of the eye. The onset of symptoms can be subtle and easily missed. The surest way to determine if you have glaucoma is to undergo a comprehensive dilated eye exam.

When you finish, remember to list the references in the order they were used. Please use English for this task.
