Cataracts: Symptoms, Causes, and Surgery for Treatment

A cataract is when part of the eye called the lens, which is normally clear, becomes cloudy and affects your vision. It tends to affect older people – up to one in three of those over 65 are affected by cataracts. There are other rarer types of cataracts such as congenital cataracts that develop from birth, and this is checked at your baby's 6 to 8 week screening with your doctor. People with a cataract usually complain of blurred vision. As the condition progresses over years, vision can worse, colours look less vibrant, spots appear in their vision, halos appear around lights, lights seem too bright and they have difficulty seeing in poor light or at night. Pain isn’t usually a symptom. Symptoms of a cataract usually develop slowly over a few years so people may not notice at first, but it will be picked up at a routine eye test.

Optrex Bacterial Conjunctivitis Ointment: Use and Relief

Optrex Bacterial Conjunctivitis Eye Ointment is used to treat minor bacterial eye infections (such as bacterial conjunctivitis). It contains the active ingredient chloramphenicol, a broad-spectrum antibiotic that works against a wide variety of bacteria. Optrex Bacterial Conjunctivitis Eye Ointment can be used in adults and children over the age of 2 years and purchased from your pharmacy after discussing the symptoms with your pharmacist. In some situations, your pharmacist may suggest an alternative eye treatment that could be more appropriate than chloramphenicol. Viral and fungal eye infections can cause very similar symptoms but need different treatments. Optrex Bacterial Conjunctivitis Eye Ointment can be used on its own or together with chloramphenicol eye drops, however, this is normally through the direction of the doctor. It is used in combination with chloramphenicol eye drops because the ointment lasts longer in the eyes, making them more suitable for the before-bed application.

Glaucoma: Symptoms, Causes & Treatment Options

Glaucoma is a condition where there is damage to the optic nerve. This nerve sits at the back of your eye and transports the images your eyes see to your brain for processing. Glaucoma can threaten your vision, either by direct damage to the optic nerve, or by an increase in pressure in the fluid filling the eye, and thereby squeezing the optic nerve. It can ultimately lead to a loss of vision, so it's important it's detected and treated early. There are two usual types of glaucoma, based on whether pressure increases slowly or quickly. Chronic open-angle glaucoma - the most common type - is where pressure inside the eye builds slowly, so the loss of vision occurs gradually. You might not even notice changes early on, but you're most likely to lose vision in the outer edges of your vision (the periphery) first. It's often picked up on a routine check-up with your optician, where they check eye pressure by blowing a puff of air on your eyeball. This type of glaucoma usually affects both eyes and is painless.  Among white Europeans, about 1 in 50 people over 40 years of age and 1 in 10 people over 75 years of age have chronic open-angle glaucoma. Acute angle glaucoma is much less common. Pressure builds rapidly inside the eye and threatens vision if not treated urgently. You might feel severe pain in or around your eye or in the head, the eye may feel tight or full, lights may appear to have halos around them and you might complain of blurred vision. You may even feel unwell and be vomiting. This is an emergency and you should seek medical attention urgently. Other possible types of glaucoma include secondary glaucoma – caused by an eye injury or inflammation of the middle layer of the eye – and congenital glaucoma which is rare but present at birth.
