It can cause changes in the eyes, but the most common are tiny corneal deposits, known as cornea verticillata, which are usually harmless.

Yes, sildenafil can sometimes affect your vision. You may notice temporary blurred vision, increased sensitivity to light or changes in how you see colours after taking it.

Yes, hydroxychloroquine can damage your retina, particularly when you take it for many years or at higher doses. Early retinal damage may not cause symptoms you notice, so you may need regular eye monitoring to detect changes before significant sight loss occurs. Hydroxychloroquine remains an important treatment for conditions such as lupus and rheumatoid arthritis, so you should not stop taking it without medical advice. In the UK, annual retinal monitoring is generally recommended after five years of treatment if

Ozempic and other GLP-1 medicines can be associated with certain eye-related changes, but the risks differ depending on the medicine, your diabetes control and any existing eye disease. If you have diabetes, one concern is diabetic retinopathy, which can temporarily worsen when your blood glucose falls very quickly.

You may develop raised eye pressure, which can lead to glaucoma, or cataracts that affect your vision. This does not mean you should avoid steroids prescribed by your doctor.

The exact cause of his permanent vision loss is uncertain, although doctors found a vitreous haemorrhage and later a mature cataract.
