BVP - Paediatric Ocular and Systemic Conditions - Week 10 Flashcards
List 5 general paediatric ocular conditions optometrists might need to manage? Note which role, optometrist or ophthalmologist, manages each case best. Also note the most and second most common conditions.
Refractive error - most common -optometry Accommodation-vergence dysfunction - second most common -optometry Strabismus or BV dysfunction -optometry/ophthalmology Amblyopia -optometry/ophthalmology Anterior/posterior eye conditions -optometry/ophthalmology
List 7 general management options available to presentations typical of paediatric populations.
Spectacle/CL correction Medical therapy Vision therapy Referral coordination and follow-up Monitor and review Reassurance and routine review Professional advice and recommendations
List the guidelines most helpful in screening for amblyogenic potential for the following conditons: Hyperopia Myopia Astigmatism (including oblique axis (2)) Anisometropia
Hyperopia >+3.50D Myopia >-3.00D Astigmatism >1.50D at 90/180 >1.00 at oblique axes Anisometropia >1.50D
Are babbies born hyperopic or myopic?
Hyperopic
What is the guideline for managing hyperopic refractive error for children aged 1-4 (2)?
If the refractive error is >+3.50, prescribe 1D less
What is the guideline for managing hyperopic refractive error for children aged 4-5 (2)?
If the refractive error is >+2.50, prescribe 1D less
What is the guideline for managing myopic and hyperopic refractive error for children aged 5+ (3)?
If the refractive error is >+1.50, give the full prescription
If the prescription is myopic (any magnitude), give the full prescription
If myopic with esophoria, give near add
What is the guideline for managing anisometropic refractive error for children age 3.5+?
If >1.00 anisometropic, prescribe in full
What is the guideline for managing astigmatic refractive error for children age 4+?
If >1.50 astigmatic, prescribe in full
What is a retinoblastoma? Is it malignant or benign?
Malignant tumour of embryonic retinal cells
What can be seen during the first two years of life with retinoblastoma?
Leukocoria (white milky pupillary reflex)
How serious is retinoblastoma?
Very serious, requiring immediate referral
How does cataract appear paediatrically? Describe the red reflex, vision, and what it might appear to look like.
Limited or no red reflex
Poor sight
May look like leukocoria
What is ectopia lentis and what is it associated with?
Connective tissue defect often associated with Marfan syndrome
What is aniridia? What is often seen with this condition (2)? What is vision like, and is it uni- or bilateral?
No iris Cataracts oftenseen Nystagmus Poor vision Bilateral
What is microphthalmos? What is also seen with this condition (2)?
Small globe
Marked hyperopia
Macular hypoplasia
What is optic nerve hypoplasia? What is vision like? Is it easy to determine a mild case? Is it uni- or bilateral? How is it defined?
Small grey optic nerve Reduced or normal vision Difficult to detect if mild May be uni- or bilateral Defined by size of the disc relative to distance from the disc to the macula
What is retinopathy of prematurity? What can be seen with this condition (4)?
Incomplete retinal vessel growth leading to vascular changes Retinal detachment Vessel tortuosity Neovascularisation Haemorrhage
List three risk factors for retinopathy of prematurity.
Prematurity (<30 weeks)
Low birth weight (<1.5kg)
Supplemental O2 at birth
What is papilloedema? Is it uni- or bilateral? What is the vasculature like? List three causes.
Bilateral swelling of the disc
Vascular tortuosity seen
Possible causes are brain tumours, hydrocephalus, and acute disseminated encephalomyelitis
Describe optic nerve head drusen, the percentage incidence in children, what the deposits are, and a possible cause. What can it give rise to?
0.4%
Acellular calcified deposits with a lumpy bumpy appearance
Causes unknown but potentially high hyperope
Can give rise to VF defects
What is toxoplasmosis? List an additional condition typical of this and is it self limiting or does it require intervention? Describe what it looks like (4).
Infection carried from cat faeces
Posterior uveitis, which is self limiting generally
Atrophic scarr and a round pigmented edge at the posterior pole and macula
Describe static lesions and progresive lesions in toxoplasmosis. Note which is active and inactive inflammation.
Static - chorioretinitis pigmented - inactive
Progressive - has a foggy headlight appearance - active
What does toxocariasis typically cause and what is it carried by? What age is it usually seen in?
Typically cases posterior uveitis
Worm-like parasite infection living in the retina, spread by dog faeces
Typically seen in ages 4-8
What is the most common form of macula degeneration in children? Is it uni- or bilateral? Is it common or rare? What is the mode of inheritance? What is vision like?
Stargardt’s disease - fundus flavimaculatus
Bilateral, quite rare
Autosomal recessive
Loss of central vision in school age or first 20 years
