There are many diseases known to cause ocular or visual changes. Diabetes , for example, is the leading cause of new cases of blindness in those aged 20–74, with ocular manifestations such as diabetic retinopathy and macular edema affecting up to 80% of those who have had the disease for 15 years or more.
The term childhood disease refers to disease that is contracted or becomes symptomatic before the age of 18 or 21 years old. Many of these diseases can also be contracted by adults. Some childhood diseases include:
Leber's congenital amaurosis (LCA) is a collection of inherited, degenerative eye disorders that can reduce the strength of visual clarity or sharpness in infants and can cause childhood blindness. [ 14 ] [ 15 ] These eye disorders are mostly autosomal recessive diseases, and diagnoses of LCA are linked to multiple gene variants, including the ...
Any disease that causes vision loss may also cause strabismus, [34] but it can also result from any severe and/or traumatic injury to the affected eye. Sensory strabismus is strabismus due to vision loss or impairment , leading to horizontal, vertical or torsional misalignment or to a combination thereof, with the eye with poorer vision ...
Paroxysmal tonic upgaze (PTU) of childhood is a rare and distinctive neuro-ophthalmological syndrome characterized by episodes of sustained upward deviation of the eyes. Symptoms normally appear in babies under one year of age and are characterized by an upward stare or gaze, with the eyes rolled back, while the chin is typically held low.
Around 6% of infants have congenital nasolacrimal duct obstruction, or dacryostenosis, usually experiencing a persistent watery eye even when not crying. If a secondary infection occurs (dacryocystitis), purulent (yellow / green) discharge may be present. Most cases resolve spontaneously, with antibiotics reserved only if conjunctivitis occurs.
LCA symptoms typically begin in the first few months of life, most commonly with involuntary twitching of the eye . Affected infants may show misaligned eyes when looking at something ( strabismus ), aversion to light ( photophobia ), and poke or rub at their eyes (Franceschetti’s oculodigital sign). [ 9 ]
