Summary
Terson's syndrome can cause bilateral subretinal hemorrhage from the optic disc, leading to enlarged blind spots. This condition, linked to intracranial pressure, may result in permanent visual field defects.
Area of Science:
- Ophthalmology
- Neurology
Background:
- Terson's syndrome is characterized by vitreous hemorrhage following subarachnoid hemorrhage.
- Intracranial hypertension is a known risk factor.
Observation:
- A case of Terson's syndrome presented with bilateral subretinal hemorrhage originating from the peripapillary region.
- Initial CT scan revealed vitreous hemorrhage; surgery uncovered subretinal hemorrhage.
Findings:
- Subretinal hemorrhage, though resolving, correlated with persistent enlargement of the Mariotte blind spot.
- Optical coherence tomography (OCT) and Goldmann perimetry confirmed visual field defects.
Implications:
- Peripapillary structural disturbance from intracranial hypertension may cause subretinal hemorrhage in Terson's syndrome.
- This can lead to irreversible visual field deficits, highlighting the need for careful monitoring.

DefinitionDiabetic retinopathy is a microvascular complication of diabetes affecting the retinal blood vessels.Risk FactorsDiabetic retinopathy is present in almost all individuals with type 1 diabetes and more than 60% of those with type 2 diabetes after two decades of disease.The risk increases with poor glycemic control, hypertension, dyslipidemia, smoking, pregnancy, and puberty.Although cataracts and glaucoma are also more frequent in people with diabetes, retinopathy remains the leading...
01:22Photoreceptors and Visual Pathways
At the molecular level, visual signals trigger transformations in photopigment molecules, resulting in changes in the photoreceptor cell's membrane potential. The photon's energy level is denoted by its wavelength, with each specific wavelength of visible light associated with a distinct color. The spectral range of visible light, classified as electromagnetic radiation, spans from 380 to 720 nm. Electromagnetic radiation wavelengths exceeding 720 nm fall under the infrared category, whereas...
