Behin the eye both vein and artery pass through a sheath that flexes only a very little. With hjigh blook pressure (Hypertension) the rtery can swell inside the sheath. the resulting pressure on the vein can lead to a "bulge" in the vein. If this bursts sight becomes blurred. In some cases the condition clears. In some sight is permanently damaged and laser treatment required to prevent glaucoma. Prevention is by controlling blook pressure by medication, fitness and adjustment of lifestyle.
