The key difference between foveal and peripheral vision is that foveal vision is used to observe highly detailed objects, while peripheral vision is used to observe broad spatial scenes and large objects. Vision is an extremely complex sense. It has two systems: foveal (central vision) and peripheral vision. Central vision is the system that helps […]
What is the Difference Between Macular Degeneration and Glaucoma
The key difference between macular degeneration and glaucoma is that macular degeneration is an eye condition that causes central vision loss while glaucoma is an eye condition that causes peripheral vision loss. Macular degeneration and glaucoma are two eye conditions that cause vision loss. However, macular degeneration affects the macula of the eye and causes […]
What is the Difference Between Retinoschisis and Retinal Detachment
The key difference between retinoschisis and retinal detachment is that retinoschisis is a condition where the retina of the eye divides into two or more layers, while retinal detachment is a condition where the retina lifts away from the back of the eye. The retina is the innermost light-sensitive layer of tissue of the eye. It can […]
What is the Difference Between Clogged Tear Duct and Pink Eye
The key difference between clogged tear duct and pink eye is that a clogged tear duct is an eye condition due to partial or complete obstruction in the tear drainage system, while pink eye is an eye condition due to the inflammation or infection of the transparent membrane that lines the eyelid and eyeball. Clogged tear […]
What is the Difference Between Saccades and Nystagmus
The key difference between saccades and nystagmus is that saccades are normal quick jerks, like eye movements that shift the centre of gaze from one part of the visual field to another, while nystagmus is a vision condition that results in rapid, repetitive, uncontrolled side-to-side, up and down or circular motion of the eyes. There are four […]
What is the Difference Between Hordeolum and Chalazion
The key difference between hordeolum and chalazion is that hordeolum is a painful infectious condition on the edge of the eyelid that comes on quickly, while chalazion is a less painful, non-infectious condition on the inside edge of the eyelid that prevails for a long duration. Hordeolum and chalazion are two different conditions of the […]
What is the Difference Between Pterygium and Pseudopterygium
The key difference between pterygium and pseudopterygium is that pterygium is a condition that causes fleshy overgrowth of the conjunctiva in the eye, while pseudopterygium is a condition that causes adhesion of the conjunctiva to the peripheral cornea. Pterygium and pseudopterygium are two different ocular surface disorders. However, they are different eye diseases with different aetiologies. Pterygium […]
What is the Difference Between Orbital and Preseptal Cellulitis
The key difference between orbital and preseptal cellulitis is that orbital cellulitis is an infection in the contents of the orbit, including fat and ocular muscles, while preseptal cellulitis is an infection in the anterior portion of the eyelid that does not involve the orbit or other ocular structures. Cellulitis is a bacterial infection that […]
What is the Difference Between Corneal Dystrophy and Degeneration
The key difference between corneal dystrophy and degeneration is that corneal dystrophy is the building up of foreign material in one or more layers of the cornea due to genetic changes, while corneal degeneration is a change or gradual deterioration in the tissue of the cornea due to certain diseases or aging. The cornea is […]
What is the Difference Between Glaucoma and Ocular Hypertension
The key difference between glaucoma and ocular hypertension is that glaucoma is a condition that causes high pressure alongside optic nerve damage and visual field loss, while ocular hypertension is a condition that only causes raised pressure within the eye. Glaucoma and ocular hypertension are two associated conditions that affect eye health. This is because […]
