The principles
The goal of every glaucoma treatment is to lower the eye pressure – the only approach proven to slow progression. Studies clearly show that lowering pressure prevents or slows vision loss. There are three principles, often combined:
Eye drops:
lower the pressure either by reducing how much aqueous humour is produced or by improving its drainage. They are usually the first step and must be used regularly and long term.
Laser treatment:
gently improves the natural drainage (in open-angle glaucoma) or, in a narrow angle, creates a small opening in the iris so the fluid can circulate again. Laser can add to drops or, in suitable cases, be used as the first treatment.
Surgery:
creates a new or better drainage path when drops and laser are not enough. There are gentler and larger procedures; the right one depends on the form and severity.
Your ophthalmologist decides individually. Important: treatment stops progression but does not bring back vision already lost – so every day gained early matters.
