New medical and surgical therapeutic approaches.

Glaucoma affects around 5 per cent of the population aged 60 and above, and its percentage increases with age, essentially as a result of increased eye strain.

It has a slow, insidious onset and no symptoms are noticed by the patient except in the late stages.

The disease should therefore be systematically screened for in adults, at least every year in the elderly and every 2 years in young or middle-aged adults.

Conventional treatment consists of applying drops to lower eye strain.

Today, laser treatment can reinforce the effect of, or, in the initial stages, totally or partially replace the use of eye drops.

Surgery, which was previously reserved for extreme cases in which 3 or 4 drops of a different type were not enough to control the disease, is now being used at an earlier stage due to the existence of much less aggressive and therefore less risky techniques.

These include non-penetrating deep partial sclerotomy, stents in the aqueous humour outflow channel, catheterisation of the aqueous veins and Schlemm's canal, and finally valves.
