Vitreous floaters- MedGen UID:
- 5217
- •Concept ID:
- C0016242
- •
- Finding
Deposits of various size, shape, consistency, refractive index, and motility within the eye's vitreous humor, which is normally transparent.
Lens subluxation- MedGen UID:
- 9718
- •Concept ID:
- C0023316
- •
- Disease or Syndrome
Partial dislocation of the lens of the eye.
Retinal detachment- MedGen UID:
- 19759
- •Concept ID:
- C0035305
- •
- Disease or Syndrome
Primary or spontaneous detachment of the retina occurs due to underlying ocular disease and often involves the vitreous as well as the retina. The precipitating event is formation of a retinal tear or hole, which permits fluid to accumulate under the sensory layers of the retina and creates an intraretinal cleavage that destroys the neurosensory process of visual reception. Vitreoretinal degeneration and tear formation are painless phenomena, and in most cases, significant vitreoretinal pathology is found only after detachment of the retina starts to cause loss of vision or visual field. Without surgical intervention, retinal detachment will almost inevitably lead to total blindness (summary by McNiel and McPherson, 1971).
Cataract- MedGen UID:
- 39462
- •Concept ID:
- C0086543
- •
- Disease or Syndrome
A cataract is an opacity or clouding that develops in the crystalline lens of the eye or in its capsule.
Lattice retinal degeneration- MedGen UID:
- 102321
- •Concept ID:
- C0154856
- •
- Disease or Syndrome
High myopia- MedGen UID:
- 78759
- •Concept ID:
- C0271183
- •
- Disease or Syndrome
A severe form of myopia with greater than -6.00 diopters.
Peripheral vitreoretinal degeneration- MedGen UID:
- 481979
- •Concept ID:
- C3280349
- •
- Finding
A type of vitreoretinal degeneration with manifestations that are concentrated at the periphery of the retina.
Mildly reduced visual acuity- MedGen UID:
- 1671080
- •Concept ID:
- C4732817
- •
- Finding
Mild reduction of the ability to see. On the 6m visual acuity scale, mild reduction is defined as less than 6/12 but at least 6/18. On the 20ft visual acuity scale, mild reduction is defined as less than 20/40 but at least 20/70. On the decimal visual acuity scale, mild reduction is defined as less than 0.5 but at least 0.3.
