What is a coloboma and can it affect my eye or vision?
A coloboma in the eye is known as the region where tissue is missing. A person’s eye has colobomas when they are born. One or both of your eyes may be affected. The colobomas that are most well-known and frequent impact the iris (the colored tissue of the eye) and give your pupil a keyhole […]
Sickle Cell Retinopathy
A series of blood abnormalities that result in the breakdown and misformation of red blood cells, is sickle cell disease. Sickle cell retinpathy occurs when the sickle shaped red blood cells obstructs the blood arteries in the choroid, a thin layer of tissue that is a portion of the middle layer of the wall of […]
What is anisometropia ?
Anisometropia refers to an imbalance in focus between the two eyes caused by different refractive powers in the two eyes (glasses prescription). This frequently results in asymmetric curvature (astigmatism), asymmetric far-sightedness (hyperopia), or asymmetric near-sightedness (myopia) because one eye is somewhat different in size or shape from the other. Children who have anisometropia may develop […]
What causes red eye?
The conjunctiva is a layer of tissue that covers the inside of the eyelids and the front of the eyeball (the white area of the eye), but not the cornea (the coloured looking part of the eye). It aids in shielding the eye from irritants like smoke, airborne bacteria, and allergies, as well as the […]
Why are eye exams needed for people with diabetes?
Diabetic retinopathy screenings are essential. Diabetes is a systemic disease; however, it can affect the eye as well. The effect on the eye can be as dire as blindness. Hence, it is imperative that diabetic screening be carried out to prevent the loss of vision. Screening can tell you if you need treatment to slow […]
Why can’t I see at a distance?
Nearsightedness, or myopia, is when near objects appear clear but distant objects appear blurry. This happens when light rays incorrectly bend (refract) due to the shape of the eye or specific portions of the eye. Normally, light rays should fall on the retina (the back portion of the eye), to give a clear image. In […]
Why can’t I see up close?
Presbyopia is a refractive error that makes it challenging for middle-aged and older persons to see details up close. It occurs as a result of the lens’ (an inner eye component that aids in eye focus) failure to properly concentrate light on the retina (a light-sensitive layer of tissue at the back of the eye). […]
Explaining Sixth Nerve Palsy And Why It Causes Double Vision
When the sixth cranial nerve, (also known as the abducens nerve) is injured or malfunctions, it becomes difficult to move the eyes in certain directions. The lateral rectus muscle of the eye receives signals from the sixth cranial nerve and enables the eye to move in a lateral direction. Each lateral rectus muscle in each […]
Why am I seeing double?
Double vision, or diplopia, is when a single object appears to be in two different ways when looking at it.Double vision is typically a transient problem. However, it can sometimes be a symptom of a more serious, underlying medical issue. Hence, it is important that any changes in your eyesight be tested right away. Diplopia […]
Explaining Thyroid Eye Disease.
Individuals suffering from thyroid disease may at times develop thyroid disease. Occasionally, symptoms of thyroid eye disease may be the precursor in diagnosing any underlying thyroid disease. According to research, an autoimmune condition is the root cause of thyroid disease and thyroid eye disease. Immune system imbalance or recognition issue occurs. Our immune systems typically […]
