Retinopathy of Prematurity
Incomplete retinal vessel growth leads to vascular disruption, can result in detachment and vessel tortuosity. Plus disease (stages I to IV) based on neovascularisation and haemorrhages. Parents may forget during history; need to ask Were there any issues at birth?.
Prematurity of <30 weeks, birth weight below 1.5kg, and/or getting supplemental oxygen at birth. The last point triggers ADE in retina and retinal vessel growth; kids often require laser treatment at birth.

Papilloedema - comanaged with ophthalmology
Usually bilateral with vascular tortuosity and swelling of the disc. Results from raised intracranial pressure due to brain tumours, hydrocephalous, acute disseminated encephalomyelitis.

Optic nerve head drusen
Usually unilateral but can be bilateral. Drusen is acellular calcified deposits and results in a lumpy, bumpy appearance. The cause is unknown, but may be associated with high hyperopia.

Toxoplasmosis
Infection carried from cat faeces. Big signs are posterior uveitis which is generally self-limiting and an atrophic scar that has a round, pigmented edge at the posterior pole and macula.
Two forms:
static lesion/inactive - chorioretinitis that is pigmented
progressive lesion/active - active inflammation with a foggy appearance

Toxocariasis
Infection carried from dog faeces. Big signs are posterior uveitis and a worm-like parasite infection living in retina. Common in 4-8 year olds.

Fundus flavimaculatus
Otherwise known as Stargardt Disease.
Most common form of macular degeneration in children; involves progressive loss of central vision and is laterality. Follows an autosomal recessive inheritance pattern and is quite rare, 1 in 10,000 children. Loss of central vision in school age or first 20 years of life.

Congenital/Childhood glaucoma - presentation
Cornea looks enlarged, swollen, and hazy. Affects 0-3 year olds and generally won’t be seen after the higher age untreated. Other symptoms: photophobia, excessive tearing, blepharospasm, and elevated IOP. Affects males more than females. Typically bilateral but very rare; if unilateral, one eye is larger.

Glaucoma - definition and management
Definition: IOP > 21mmHg, disc cupping or asymmetry, corneal oedema and enlarged diameter, myopic shift, and visual field defect.
Management: immediate referral, exam under general anaesthetic, typically surgical treatment, drops are temporary, and high risk of impaired visual development, myopia, and amblyopia.
Factors that place children at risk of visual impairment or reduced visual functioning
(9 points)
- Prematurity
- Low birth weight
- Oxygen at birth
- Infection of mother during pregnancy
- Difficult or assisted labour
- High refractive error
- Strabismus
- Anisometropia
- Known or suspected CNS dysfunction developmental delay, cerebral palsy, seizures, or hydrocephalus

Down syndrome
Genetic condition, extra chromosome 21. From conception with no social or ethnic pattern and affects 1 in 700 babies worldwide. Ocularly manifests as: strabismus, amblyopia, high refractive error, sensitivity to medication, reduced accommodation function, and vision impairment and/or cataract.

Cerebral palsy
Permanent, non-progressive disorder of movement and posture caused by damage to developing brain (pre-natal trauma thought to be the cause of 75% of cases).
In Australia, 1 child is born with CP every 18 hours and is the most common disability in Australia. Risk is greater in babies with low birth weight. Ocularly manifests as visual impairment, high refractive error, strabismus, and cataract.

Cerebral Palsy - Cortical/Cerebral Visual Impairment (CVI)
A deficit of visual function caused by damage to or malfunctioning of retro-geniculate visual pathways; posterior to the LGN. Affects the optic radiations, occipital cortex, and/or visual associative areas. Common complication of cerebral palsy and affects 60-70% of children and has variable effect on VA. Can see lesions with CT scans.

Autism Spectrum Disorder
Lifelong developmental difference; results in difficulty with social interaction, impaired communication, restricted and repetitive interests and behaviours, and sensory sensitivities. Effects of autism can be minimised with early intervention programs. Ocularly manifests as avoidance of eye contact, excessive blinking, strabismus, amblyopia, anisometropia, visual motor and sequencing problems, accommodation dysfunction, and astigmatism, but visual processing is usually very well developed.
