List of the Eye Diseases
Here is a list of some common eye diseases that can affect vision and ocular health:
- Cataracts - Cloudy areas in the lens causing blurred vision. Caused by ageing, prior injury, radiation exposure etc.
- Glaucoma - Damage to optic nerve from high eye pressure. Can lead to vision loss.
- Age-related macular degeneration - Damage to the retina's macula in seniors. Causes central vision loss.
- Diabetic retinopathy - Damaged retina blood vessels due to high blood sugar in diabetes.
- Dry eye disease - Insufficient tear production causing irritated eyes.
- Conjunctivitis - Pink eye, inflammation of conjunctiva due to viruses, bacteria or allergens.
- Retinal detachment - Separation of the retina's photosensitive layer from the blood supply. Causes visual defects.
- Blepharitis - Swelling of eyelids with crusting and irritation of eyelash roots.
- Strabismus - Misalignment of eyes. Can cause double vision.
- Amblyopia - Poor vision in one or both eyes due to the brain's inability to process images. Common in children.
- Colour blindness - Inability to distinguish certain colours due to cone photoreceptor defects.
Regular eye exams help detect these and other ocular conditions early for proper treatment aimed at restoring or preserving vision.
What is glaucoma eye disease?
Glaucoma is a term that refers to a group of eye diseases that can damage the optic nerve, which is responsible for transmitting visual information from the eye to the brain. Optic nerve damage is often associated with high pressure in the eye, but it can also occur with normal eye pressure. Glaucoma can cause vision loss and blindness if left untreated.
There are different types of glaucoma, such as open-angle glaucoma, angle-closure glaucoma, normal-tension glaucoma, and congenital glaucoma. Each type has different causes, symptoms, and treatments. Some common symptoms of glaucoma are:
- Patchy blind spots in your side or central vision
- Severe headache and eye pain
- Nausea and vomiting
- Blurred vision
- Halos or coloured rings around lights
- Eye redness
However, some types of glaucoma have no noticeable symptoms until the condition is advanced. Therefore, it is important to have regular eye exams that include measurements of your eye pressure and optic nerve health. Early detection and treatment can help prevent or slow down vision loss from glaucoma.
List of Lab Tests for the Eye Diseases
Here is a list of some common lab tests used to diagnose and monitor eye diseases:
- Complete Blood Count (CBC) - Anemia, infections
- Blood glucose tests - Diabetes-related eye diseases
- Lipid profile - Hardening of retinal blood vessels
- Thyroid tests - Thyroid eye disease
- Haemoglobin A1C - Blood sugar control for diabetes
- C-reactive protein (CRP) - Inflammation marker for uveitis
- Erythrocyte sedimentation rate (ESR) - Also screens inflammation
- Antinuclear antibody test - Autoimmune disorders like lupus
- Angiography - Retinal blood vessel assessment
- Eye swab cultures - Identifies bacterial/fungal infections
- Serology tests - Measles, toxoplasmosis antibodies
- Genetic testing - Inherited retinal diseases
- Optical coherence tomography - Detailed cross-section retinal images
- Fundus imaging - Photographs interior eye structures
These tests help diagnose the cause of visual symptoms, guide treatment approaches, and monitor the progression of ocular diseases affecting the retina, optic nerve head, lens, and other eye structures.
