Both conditions can occur independently or as part of a syndrome that includes other systemic abnormalities. Early detection and awareness are critical for...
Anisometropia.
Introduction to Anisometropia Anisometropia is a common ocular condition that causes a significant difference in refractive power between the two eyes. This difference can result in unequal focus, causing one eye to be more nearsighted, farsighted, or astigmatic than the other. If left untreated, anisometropia can cause amblyopia (lazy eye) and other visual problems. Early detection and treatment are critical...
Anisocoria.
What is Anisocoria? Anisocoria is a condition defined by unequal pupil sizes in the eyes. It is a fairly common finding that can be physiological (normal) or pathological (indicating an underlying condition). The pupils, which control the amount of light entering the eyes, are usually the same size and respond similarly to light. However, in cases of anisocoria, one pupil...
Aniridia: Key Facts and Information
What is Aniridia? Aniridia is a rare congenital eye condition marked by the partial or complete absence of the iris, the colored part of the eye that regulates the amount of light that enters the eye. This condition is usually present from birth and affects both eyes. Aniridia can cause a variety of visual impairments and is frequently associated with...
Amblyopia: Key Facts and Solutions
What is Amblyopia? Amblyopia, also known as "lazy eye," is a visual development disorder in which one eye does not achieve normal visual acuity, even with prescription glasses or contact lenses. It usually begins during infancy or early childhood. Early detection and treatment are critical because if left untreated, amblyopia can cause permanent vision impairment. Awareness of this condition is...
Albinism (Ocular and Oculocutaneous).
Introduction to Albinism Albinism is a genetic condition defined by a lack of melanin pigment in the skin, hair, and eyes. This condition affects people worldwide, regardless of race or ethnicity, and is divided into two types: ocular albinism, which primarily affects the eyes, and oculocutaneous albinism, which affects the eyes, skin, and hair. Awareness and early detection of albinism...
Age-related macular degeneration (AMD).
What is age-related macular degeneration (AMD)? Age-related macular degeneration (AMD) is a common eye condition that primarily affects people over the age of 50. This degenerative disease affects the macula, the central portion of the retina that is responsible for the sharp and central vision required for tasks such as reading, driving, and recognizing faces. As AMD progresses, it can...
Adie’s Pupil: Key Facts and Tips
What Is Adie's pupil? Adie's pupil, also known as tonic pupil, is a neurological condition in which the eye's pupil reacts abnormally to light. This condition usually manifests as a unilateral, enlarged pupil that reacts slowly to direct light but constricts more quickly during near vision tasks, a phenomenon known as light-near dissociation. While Adie's pupil is typically benign, it...
Comprehensive Guide to Ocular Actinic Keratosis
What is Ocular Actinic Keratosis? Ocular actinic keratosis is a rare but serious eye condition caused by prolonged exposure to ultraviolet (UV) radiation. While actinic keratosis is most commonly associated with the skin, resulting in rough, scaly patches in sun-exposed areas, its ocular variant causes similar changes in the tissues of the eye, specifically the conjunctiva. This condition primarily affects...
Eye condition: “Acrochordon (skin tags)”
Introduction to Acrochordon Acrochordon, also known as skin tags, is a benign condition marked by small, soft, flesh-colored growths that appear in areas where the skin creases.

Awareness and early detection of acrochordons are critical for effective...
Achromatopsia: Causes, Symptoms, and Management
What is Achromatopsia? Achromatopsia, also known as total color blindness, is a rare hereditary eye condition marked by a complete inability to perceive color.
