An A-Z of Eye Conditions | Understanding Your Eyes

Do You Have an Eye Condition?

At OCL Vision, we provide our patients with comprehensive eye care and education. Understanding various eye conditions is crucial for maintaining good eye health and seeking appropriate treatment. This guide explores a range of eye conditions from A to Z, detailing their symptoms, causes, and treatments in a professional yet friendly tone.

Age-Related Macular Degeneration (AMD)

Age-related macular degeneration, commonly called AMD, is a leading cause of vision loss in individuals over 50. This condition affects the macula, the central part of the retina responsible for sharp vision. Symptoms often include blurred vision, dark or empty areas in the centre of vision, and difficulty recognising faces. The exact cause of AMD is not entirely understood, but factors such as age, genetics, smoking, and diet can contribute. While there is no cure, treatments like anti-VEGF injections, laser therapy, and dietary supplements can slow its progression and help manage symptoms.

Blepharitis

Blepharitis is an inflammation of the eyelids that can cause discomfort and irritation. Common symptoms include red, swollen eyelids, a gritty sensation in the eyes, crusting at the base of the eyelashes, and burning or stinging sensations. Blepharitis can result from bacterial infections, seborrheic dermatitis, or malfunctioning oil glands in the eyelids. Treatment typically involves maintaining good eyelid hygiene, using warm compresses, and applying prescribed antibiotics or steroid eye drops to reduce inflammation and bacterial growth.

Cataracts

Cataracts are a common condition in which the eye’s natural lens becomes cloudy, leading to vision impairment. Symptoms include blurred vision, difficulty seeing at night, sensitivity to light, and halos around lights. Cataracts often develop slowly and are primarily caused by ageing, but other factors such as diabetes, smoking, and prolonged exposure to sunlight can accelerate their formation. The primary treatment for cataracts is surgical removal of the cloudy lens and replacement with a clear artificial lens, significantly improving vision.

Diabetic Retinopathy

Diabetic Retinopathy is a complication of diabetes that affects the blood vessels in the retina. High blood sugar levels can damage these vessels, leading to leakage, swelling, and abnormal blood vessel growth, all of which can impair vision. Symptoms may include floaters, blurred vision, dark or empty areas in the vision field, and vision loss. Early detection through regular eye exams is crucial. Treatment options include managing blood sugar levels, laser therapy, and vitrectomy surgery to remove blood from the eye and repair retinal damage.

Dry Eye Syndrome

Dry Eye Syndrome occurs when the eyes do not produce enough tears or when the tears evaporate too quickly. This can lead to discomfort, itching, redness, and a gritty eye feeling. Factors contributing to dry eye include ageing, certain medications, and environmental conditions such as wind or dry climates. Treatments range from over-the-counter artificial tears to prescription medications that increase tear production. Lifestyle changes, such as taking breaks from screen time and using humidifiers, can also alleviate symptoms.

Eye Floaters

Eye floaters are small, dark, shadowy shapes that appear to float across your field of vision. They are more noticeable when looking at a plain, bright background, like a clear sky or a white wall. Floaters are usually caused by changes in the vitreous, the gel-like substance inside the eye, as it becomes more liquid with age. While generally harmless, a sudden increase in floaters or flashes of light can indicate a serious condition like retinal detachment. If this occurs, immediate medical attention is necessary.

Glaucoma

Glaucoma is a group of eye conditions that damage the optic nerve, often due to increased pressure in the eye. It is a leading cause of blindness, particularly among older adults. There are different types of glaucoma, but common symptoms include blurred vision, rainbow-coloured halos around lights, severe eye pain, and sudden vision loss. Regular eye exams are crucial for early detection. Treatments include prescription eye drops, laser treatment, and surgery to lower eye pressure and prevent further damage to the optic nerve.

Hyperopia

Hyperopia, or farsightedness, is a refractive error where distant objects are seen more clearly than close ones. This occurs because the eyeball is too short or the cornea is not curved enough, causing light to focus behind the retina. Symptoms include headaches, eye strain, and difficulty focusing on close objects. Hyperopia can be corrected with glasses or contact lenses. Refractive surgery, such as LASIK, is also an option for permanently improving vision by reshaping the cornea.

Keratoconus

Keratoconus is a progressive eye disease where the cornea thins and bulges into a cone-like shape, causing distorted vision. The cause still needs to be fully understood, but genetic and environmental factors are believed to play a role. Symptoms include blurred vision, increased sensitivity to light, and frequent changes in prescription glasses. Treatment varies depending on severity, including glasses, contact lenses, corneal cross-linking to strengthen the cornea, and corneal transplant surgery for advanced cases.

Myopia

Myopia, or short-sightedness, is a common condition where close objects are seen clearly, but distant objects appear blurred. This is due to an elongated eyeball or an overly curved cornea, causing light to focus in front of the retina. Symptoms include squinting, eye strain, and difficulty seeing distant objects. Myopia is commonly corrected with glasses or contact lenses. Refractive surgeries such as LASIK or SMILE can offer a permanent solution by reshaping the cornea to improve focus.

Nystagmus

Nystagmus is characterised by involuntary, repetitive eye movements that can affect vision. These movements can be horizontal, vertical, or circular. Causes of nystagmus include neurological problems, inner ear issues, or congenital factors. Symptoms include blurred vision, difficulty focusing, and dizziness. While there is no cure, treatments can consist of glasses or contact lenses to improve vision and, in some cases, surgery or medications to reduce eye movement.

Ocular Hypertension

Ocular Hypertension is a condition where the pressure inside the eye is higher than usual, increasing the risk of glaucoma. It does not usually cause symptoms, making regular eye exams essential for detection. Treatment typically involves medications to lower intraocular pressure and regular monitoring to prevent progression to glaucoma.

Presbyopia

Presbyopia is an age-related condition where the eye’s lens loses its flexibility, making it difficult to focus on close objects. Symptoms include difficulty reading small print, eye strain, and the need to hold reading materials further away. Presbyopia is typically corrected with reading glasses, bifocals, or progressive lenses. Surgical options like LASIK or intraocular lens implants can also address this condition.

Retinal Detachment

Retinal Detachment is a severe condition where the retina separates from the back of the eye, leading to potential vision loss. Causes include eye injuries, severe myopia, or thinning of the retina. Symptoms include sudden floaters, flashes of light, and a shadow or curtain over part of the visual field. Immediate treatment is crucial and may involve laser therapy, cryotherapy, or surgery to reattach the retina and restore vision.

Strabismus

Strabismus, commonly known as crossed eyes, is a condition in which the eyes do not align properly and point in different directions. It can be caused by muscle imbalance, neurological issues, or genetic factors. Symptoms include double vision, loss of depth perception, and eye strain. Treatment includes glasses, eye exercises, or surgery to correct the eye alignment and improve vision.

Uveitis

Uveitis is an inflammation of the uvea, the middle layer of the eye, which can cause redness, pain, and blurred vision. It can result from infections, autoimmune diseases, or trauma. Symptoms include eye pain, light sensitivity, and floaters. Treatment involves anti-inflammatory medications, antibiotics if an infection is present, and possibly immunosuppressive drugs to control inflammation and prevent further damage.
