Understanding diseases that affect the eyes
Astigmatism
Astigmatism is a common vision problem caused by an irregularity in the curvature of the cornea (the clear surface at the front of the eye) or, less frequently, the lens (the lens inside the eye). In a normal eye, the
Blepharitis
Blepharitis is a common inflammation of the eyelids, often chronic, that affects the sebaceous glands located at the base of the eyelashes. It manifests as redness, itching, burning sensations, crusts on the eyelashes, and sometimes excessive tearing. Blepharitis can be
Cataracts
A cataract is the progressive clouding of the lens, the eye’s natural lens located behind the iris and pupil. This lens, normally transparent, focuses light onto the retina, ensuring clear vision. With age, or due to certain factors, the proteins
Diabetic Retinopathy
Diabetic retinopathy is a complication of diabetes that affects the eyes. Specifically, it damages the blood vessels in the retina, the light-sensitive tissue at the back of the eye. This damage occurs because chronically high blood sugar levels can weaken
Dry Eye Syndrome
Dry eye, or dry eye syndrome, is a common problem where tears no longer sufficiently lubricate the eyes. This can be due to insufficient tear production, too rapid evaporation, or poor tear quality. You should know that Bellevue clinics have
Ectropion
A normal and healthy lower eyelid should be in contact with the eyeball. Ectropion is defined as an outward drooping, or eversion, of the eyelid margin. When ectropion is present, the eyelid is turned outwards and can no longer adequately
Entropion
In contrast to ectropion, entropion is defined as an inward turning of the eyelid. The eyelashes are then in contact with the surface of the eye, which can cause discomfort and irritation. This eye abnormality generally affects older people and
Epiphora
Epiphora is a medical term that describes excessive tearing, often to the point of overflowing onto the cheek. This phenomenon, while common, can be a source of discomfort and concern. It results from an imbalance between tear production and drainage,
Eyelid Ptosis
Palpebral ptosis, or ptosis, is the medical term used to describe the drooping of the upper eyelid. It can affect one or both eyes, and its severity can vary from case to case. Although painless, significant ptosis can noticeably affect
Glaucoma
Glaucoma is a chronic and progressive eye disease that damages the optic nerve, which is essential for transmitting visual information to the brain. This condition is often associated with an increase in intraocular pressure (IOP), although it can occur with
Macular Degeneration (AMD)
Macular degeneration is an eye disease that affects the macula, the central part of the retina responsible for sharp, detailed vision. It leads to a progressive loss of central vision, making it difficult to read, recognize faces, and perform tasks
Myopia and Hypermetropia
For an image to be perceived well, it must be perfectly centered on the retina (and not in front of or behind the retina). The focusing power and length of the eye from the cornea to the retina must match.
Narrow angles
Narrow iridocorneal angle is an eye condition where the angle between the iris and the cornea is abnormally narrow. This angle is crucial because it allows the aqueous humor, a clear fluid that fills the front of the eye, to
Palpebral Lesions
A palpebral lesion concerns any affection, benign or malignant, located on the eyelids. These include: papillomas, chalazion, warts, cysts, etc. These lesions often appear as lumps found below or above the skin. You should know that Bellevue clinics have all
Phthisis Bulbis
Phthisis bulbi, or atrophy of the eye, is the terminal stage of several serious eye pathologies. When phthisis bulbi occurs, the eye becomes soft and often painful. No longer being functional, an enucleation (removal of the eye) is then necessary.
Presbyopia
Presbyopia is a common age-related eye condition that affects the eye’s ability to focus on nearby objects. It results from a progressive loss of elasticity in the lens, the eye’s natural lens, and a decrease in the strength of the
Proptosis
Proptosis, also known as exophthalmos, is an eye condition characterized by an abnormal protrusion of the eyeball out of the orbit. This bulging of the eye can be unilateral (affecting only one eye) or bilateral (affecting both eyes), and it
Retinal detachment
A retinal detachment is a serious eye condition that requires immediate medical attention. The retina, a thin layer of nerve tissue located at the back of the eye, is responsible for converting light into electrical signals sent to the brain,
