Types of Vision Problems Blurred vision (called refractive errors) Age-related macular degeneration. Glaucoma. Cataract. Diabetic retinopathy.

Prism base out test: Ask the patient to look at a light source then a prism of 10PD is placed before the alleged blind eye with its base outward. If the eye moves inward (to eliminate diplopia) malingering is proved.

This is performed by comparing the light reflex from the cornea of both eyes. Hold a torch 1 metre in front of the eyes and look for the light reflex on the cornea (Hirschberg test). In the primary gaze (looking straight ahead at the torch light), the light reflexes should be in a symmetrical position on each cornea.

In a person with unilateral organic vision loss, we expect the visual field from the other eye to compensate for loss from the poor eye, and expect the field with both eyes open to be normal. However, in our patient it remained constricted in the right eye.

Types of blindness Low vision. If you have permanently reduced vision but retain some amount of your sight, you have low vision. ... Total blindness. Total blindness describes people with eye disorders who have no light perception (NLP). ... Congenital blindness. ... Legally blind.

Refractive errors include myopia (near-sightedness), hyperopia (farsightedness), astigmatism (distorted vision at all distances), and presbyopia that occurs between age 40–50 years (loss of the ability to focus up close, inability to read letters of the phone book, need to hold newspaper farther away to see clearly) ...

absence of usable vision with the exception of light perception. Major causes of organic blindness include inoperable cataract, uncontrolled glaucoma, retinitis pigmentosa, diabetic retinopathy, age-related macular degeneration, rubella, and brain injury.

Neuro-Ophthalmology Examination Neuro-ophthalmology examinations begin with a careful review of patient problems and relevant issues, followed by an evaluation of vision and eye movement, typically including visual acuity, color vision and visual field testing.

NLP vision may be caused by various disease processes and localize to the retina, optic nerve, chiasm, or bilateral involvement of the retrochiasmal visual path- ways. These conditions may not only have a dramatic impact on vision but may also be the first presentation of life-threatening conditions.

Vision Disorders (Neuro-Ophthalmology) Reduced vision. Blind spots. Double vision. Abnormalities of the pupils. Droopy eyelids. Abnormal alignment of the eyes. Abnormal eye movements. Vision loss from stroke or tumor.

ICD-10 code H54. 7 for Unspecified visual loss is a medical classification as listed by WHO under the range - Diseases of the eye and adnexa .

Functional Visual Loss (FVL) is a decrease in visual acuity and/or visual field not caused by any organic lesion. It is therefore also called “nonorganic visual loss” (NOVL). This entity is considered within the spectrum of “conversion disorder”, malingering, somatic symptom disorder, and “factitious disorder”.
