Myopia: Diagnosis, Teatment And Management Flashcards
Major symptom of myopia
Blurred vision
Major sign of myopia is
Reduces unaided distance visual acuity
In simple myopia and degenerative myopia, the distance blur is _____
Constant
In nocturnal myopia, distance vision is blurred when
Only in dim illumination or in dark conditions
In _________ the blurred distance vision may be constant or intermittent with greater distance blur occurring after near work
Pseudomyopia
Can have anesthopia too
When is induced myopia blurry
Vary from transient to constant, depending upon the particular agent or condition causing it
Results of retinoscopy in the dark for nocturnal myopia
May be shifted in the minus direction, compared with the standard manifest refraction
Patients with pseudomyopia frequently have ____________ that corresponds to fluctuations in accommodation
Fluctuations in distance VA
May be observable as variations in VA and retinoscopic reflex, and sometimes changes in pupils diameters
Primary correction for treatment of myopia
Optical correction
What is a concern when Rxing for myopia
Be concerned about giving the patient too much minus spherical correction
What is visual hygiene
Giving eyes a break so you don’t tire, and to make sure you are blinking right
What is one important part of visual hygiene?
Maintaining proper distance from the book
What is the distance you should be reading at and what is that called
It should be at least as far from your eyes as your elbow when you make a fist and hold it against your nose. It is called the Harmon distance
What do you tell parents that want to know if they can do anything to prevent their kids from getting more myopic?
Limit near work and make them play outside more
Patient education for nocturnal myopia
Patient should be instructed to wear the correction for nighttime seeing under dark conditions
Patient education for simple myopia
For kids, increases are not uncommon
Patient education for pseudomyopia
Tell them the goal is to relax accommodation. Explain that periods of blurred distance vision occur when accommodation is not relaxed, and that blurred distance vision may occur periodically until accommodative response is reduced
Patient education for degenerative myopia
- have annual or more frequent eye exams
- educate about the causes and symptoms of retinal break or detachment and be advised to seek immediate care if they experience the onset of symptoms
Patient education for induced myopia
- educate about the agent or condition inducing the myopia and the nature of the changes occurring in the eye.
- informed as to whether the induced myopia will be temporary or long standing
- how to avoid the induced myopia if possible
What type of myopia might benefit from vision therapy?
Pseudomyopia
