what are some common developmental disabilities
Ocular effects of Downs syndrone
What are the challenges in clinic
communication barriers - H&S, subjective
cognitive - may not understand instructions for test/ low attention span
sensory issues- hyper sensitive so need a calm environment, consider lighting, anxiety/discomfort/refusal to do certain tests
time constraint- tests may need to be in shorter seesions - avoid px fatigue = non cooperation
How do optoms overcome challenges
Modify communication- speed, clarity, calm, sign language, instruction = short and simple, respectful, non patronising, allow time for response, involve carer AND px
Gain consent- ensure px = happy to proceed with test ( close contact)
H&S- RFV, POH, GH, meds, FOH, curent signs eg head tilt, strab, eye rubbing, hobbies,
VAs- use approppriate chart ( dyslexia), be encouraging. For CS, Pelli-Robson might be complex so use Cardiff Cards
Rx- may be high, use interesting distance target, near ret( reduced acom) ( careful of room light off), cyclo( rm lights on),
Strab- CT, stereopsis ( Titmus or Randot)
Nystagmus - worse in certain directions= ocular motility
Slit lamp-( room lights off), gain consent, use volk( longer WD)
Developing a managment plan, considerations?
Rx- full +Rx, optimise near VA ( bifocals/PPLs), differentiate btwn NVA blur and diplopia
LVAs- mag, enhanced lighting/contrast, auditory devices, tinted lenses( glare), prism
consider school/ work set up, in front of class/
Follow up- 3 months
