What is Red reflex Assessment
About Red reflex Assessment
The red reflex test is vital, non-invasive test that can identify early warning signs of serious eye conditions in children, such as cataract (white water), glaucoma (blue water) and retinoblastoma (childhood eye cancer) and high refractive errors. Infants or children in whom parents or other observers describe a history suspicious for the presence of leukocoria (a white pupil reflex) in one or both eyes should be examined because small retinoblastoma tumors or other serious lesions may present in a subtle fashion.
What is Refractive Lens Exchange (RLE)
About Refractive Lens Exchange (RLE)
Refractive Lens Exchange (RLE) is a refractive surgical procedure during which the natural lens is replaced with synthetic implant called intraocular lens (IOL) it is performed to reduce the need for glasses or contact lenses.
Lens clarity and flexibility diminish with age, and many older patients who would like their sight corrected actually have the beginnings of a cataract. Replacing the natural lens is often therefore the best option for sight correction, even for patients with a lower spectacle prescription, particularly if they are longsighted.
Refractive lens Exchange is suitable for people over 50 years of age and have a glasses prescription higher than the normal range for laser eye surgery.
What is Retinal Detachment Surgery
About Retinal Detachment Surgery
Retinal detachment is a condition when the thin lining at the back of the eye (the retina) begins to come away and separate itself from the underlying wall of the eye which contains blood vessels that supply it with vital oxygen and nutrients.
If not treated promptly, retinal detachment will lead to blindness in the affected eye.
A retinal detachment is usually caused by a tear in the retina and this is termed a Rhegmatogenous retinal detachment. There are other types of retinal detachment namely Traction retinal detachment which is usually seen in advanced diabetic retinopathy and Exudative retinal detachment (usually seen in people with inflammation). It is the Rhegmatogenous retinal detachment which needs urgent surgery in most cases.
What is Retinal Photodynamic Therapy (PDT)
About Retinal Photodynamic Therapy (PDT)
Photodynamic therapy (PDT) is a treatment that uses a combination of a “cold” laser and a special light-sensitive dye (Verteporfin). This is injected into the blood stream to target abnormal leaking blood vessels in the retina (nerve tissue lining at the back of the eye which detects light and allows us to see) or the layer below the retina (choroid). PDT is used in the treatment of some specific forms of wet macular degeneration and a disease called ‘Central Serous Retinopathy’ (CSR).What is Retinal Vein Occlusion
About Retinal Vein Occlusion
Blocking of the retinal vein which reduces the vision is known as Retinal Vein Occlusion. This results in the accumulation of blood (retinal hemorrhages) and fluid (macular edema) in the retina and leads to a drop in the visual acuity (clarity of vision).
What is Retinitis Pigmentosa
About
It is the most common form of inherited retinal dystrophies and can be inherited as autosomal dominant, autosomal recessive, or X-linked trait. It is caused by genetic variants in genes coding for proteins which are important for the structure and/or function of the rod photoreceptors (which are responsible for night vision) causing night blindness, with eventual constriction of the visual field as the cone photoreceptors become affected. Some forms of retinitis pigmentosa can be associated with hearing loss, kidney disease, or learning difficulties. Early identification of these conditions allows for appropriate investigation.
What is Retinopathy of Prematurity (ROP)
About Retinopathy of Prematurity (ROP)
Retinopathy of Prematurity (also called ROP) is an eye disease that affects many premature babies. ROP happens when a baby’s retina doesn’t fully develop in the weeks after birth. As a consequence of premature birth, abnormal blood vessels are formed, which are fragile and can leak, scarring the retina and pulling it out of position. This causes a retinal detachment, which is the main cause of visual impairment and blindness in ROP. Some cases of ROP are mild and correct themselves, however, others require surgery to prevent vision loss or blindness. Surgery involves using a laser or other means to stop the growth of the abnormal blood vessels, making sure they don’t pull on the retina. As ROP has no signs or symptoms, the only way to detect it is through an eye examination by an ophthalmologist.
