Visual Analysis 1 Flashcards
Visual Pattern
Accommodative Pattern
Convergence Pattern
Neurological Pattern
Set of symptoms characteristic of a medical condition
Symptomatology
Decreased vision that is ocular in nature
Constant BOV
Decreased vision that is pathologic in nature
Intermittent BOV
Analysis:
Dry refraction VT #7: -3.00DS
Wet refraction VT #7: -1.00DS
Question: If myopia gets down after wet refraction or superfog, the patient might have?
Pseudo myopia
Analysis:
Dry refraction VT #7: = +2.50DS
Wet refraction VT #7= +4.75DS
Question: If hyperopia goes up after wet refraction or superfog, the patient might have?
Latent hyperopia
If the patient has hypertension, high blood sugar, hyperthyroid he/she might have?
Induced myopia
If patient has hyperthyroidism, hypoglycemia, or anemia, he/she might have?
Index hyperopia
BOV during night, patient might have?
Nocturnal myopia
BOV occurring in bright daylight, the patient might have?
Nuclear or posterior sub capsular cataract
BOV during transient loss of vision (amaurosis fugax), the patient might have?
Carotid artery occlusion
Temporary loss of vision is called
Amaurosis fugax
7 coatings of the lens:
Hard coat
Anti-radiation
Anti-reflection
Anti-static
Hydrophobic coat
Scratch-resistant
Another hard coating
Visible light transmission of CR-39
92%
Visible light transmission of polycarbonate
85-88%
A type of HA where the pain is constant, more or less severe, and of a deep, steady boring character
Intracranial Dse. HA
HA is generally frontal or mid-orbital, increasing in duration and in severity as the day goes by
HA in Presbyopia
HA is generally mid-orbital, but in some cases may be frontal. Condition commences earlier in the day
HA in Astigmatism
HA over brow with a tension and pulling effect. It may be unilateral radiating HA
HA in Vertical Phoria
HA coming on with near work; very similar to HA of hyperopia
HA in esophoria
HA usually on occipital but may extend to frontal region
HA in high exophoria
HA of frontal or/and mid orbital along with symptoms such as watery secretions and burning sensation
HA in hyperopia
HA accompanying changes in lens prescription should be checked with the ff characteristics
Incorrect PD
Prescription
Occurs as a recurrent episodes of bursting pain, usually worse in the morning and associated with vomiting
HA associated with brain tumor
