Ectopia lentis- MedGen UID:
- 41704
- •Concept ID:
- C0013581
- •
- Congenital Abnormality
Dislocation or malposition of the crystalline lens of the eye. A partial displacement (or dislocation) of the lens is described as a subluxation of the lens, while a complete displacement is termed luxation of the lens. A complete displacement occurs if the lens is completely outside the patellar fossa of the lens, either in the anterior chamber, in the vitreous, or directly on the retina. If the lens is partially displaced but still contained within the lens space, then it is termed subluxation.
Retinal detachment- MedGen UID:

- •
- 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.
High myopia- MedGen UID:
- 78759
- •Concept ID:
- C0271183
- •
- Disease or Syndrome
A severe form of myopia with greater than -6.00 diopters.
Persistent pupillary membrane- MedGen UID:
- 138009
- •Concept ID:
- C0344541
- •
- Congenital Abnormality
The presence of remnants of a fetal membrane that persist as strands of tissue crossing the pupil.
Iris transillumination defect- MedGen UID:
- 786045
- •Concept ID:
- C1096099
- •
- Anatomical Abnormality
Transmission of light through the iris as visualized upon slit lamp examination or infrared iris transillumination videography. The light passes through defects in the pigmentation of the iris.
Congenital ectopic pupil- MedGen UID:
- 224790
- •Concept ID:
- C1271219
- •
- Congenital Abnormality
Ectopia pupillae is a congenital eye malformation in which the pupils are displaced from their normal central position.
