Enhanced S-cone syndrome(ESCS)

MedGen UID:
341446
•Concept ID:
C1849394
•
Disease or Syndrome
Synonym: ESCS
 
Gene (location): NR2E3 (15q23)
 
Monarch Initiative: MONDO:0100288
OMIM®: 268100

Definition

An autosomal recessive retinopathy in which patients have increased sensitivity to blue light; perception of blue light is mediated by what is normally the least populous cone photoreceptor subtype, the S (short wavelength, blue) cones. Characteristics include visual loss, with night blindness occurring from early in life, varying degrees of L (long, red)- and M (middle, green)-cone vision, and retinal degeneration. [from MONDO]

Hemeralopia
MedGen UID:
42391
•Concept ID:
C0018975
•
Disease or Syndrome
A visual defect characterized by the inability to see as clearly in bright light as in dim light. The word hemeralopia literally means day blindness.

•Concept ID:
C0086543
•

Retinoschisis
MedGen UID:
56292
•Concept ID:
C0152439
•
Disease or Syndrome
Splitting of the neuroretinal layers of the retina.
See: Feature record | Search on this feature
Macular edema
MedGen UID:
75732
•Concept ID:
C0271051
•
Disease or Syndrome
Thickening of the retina that takes place due to accumulation of fluid in the macula as a nonspecific response to blood-retinal barrier breakdown. Macular edema is a common pathological response to a wide variety of ocular insults, most commonly after intraocular (e.g. cataract) surgery or in association with retinal vascular (e.g. diabetic eye disease, retinal vein occlusion) or inflammatory (e.g. uveitis) disease.

Vitreoretinopathy
MedGen UID:
87480
•Concept ID:
C0344290
•
Disease or Syndrome
Ocular abnormality characterized by premature degeneration of the vitreous and the retina that may be associated with increased risk of retinal detachment.
See: Feature record | Search on this feature
Undetectable electroretinogram
MedGen UID:
383742
•Concept ID:
C1855685
•
Finding
Lack of any response to stimulation upon electroretinography.
See: Feature record | Search on this feature
Pigmentary retinopathy
MedGen UID:
1643295
•Concept ID:
C4551715
•
Disease or Syndrome
An abnormality of the retina characterized by pigment deposition. It is typically associated with migration and proliferation of macrophages or retinal pigment epithelial cells into the retina; melanin from these cells causes the pigmentary changes. Pigmentary retinopathy is a common final pathway of many retinal conditions and is often associated with visual loss.
