Multilayered optic disc hemorrhages in adolescents
Journal of Pediatric Ophthalmology and Strabismus
|July 19, 2014
Summary
Multilayered optic disc hemorrhages in adolescents typically affect myopic eyes with crowded discs and resolve spontaneously with excellent visual outcomes.
Area of Science:
- Ophthalmology
- Retinal Diseases
- Pediatric Ophthalmology
Background:
- Multilayered optic disc hemorrhages are a specific type of retinal hemorrhage.
- Understanding their characteristics in adolescents is crucial for diagnosis and management.
Purpose of the Study:
- To delineate the clinical features of multilayered optic disc hemorrhages in adolescent patients.
- To identify associated ocular and disc anomalies.
Main Methods:
- Retrospective analysis of adolescent cases with multilayered optic disc hemorrhages (1994-2012).
- Detailed recording of hemorrhage characteristics and disc anatomy.
- Utilized spectral-domain optical coherence tomography (SD-OCT) and other imaging in select cases.
Main Results:
- The study included 16 adolescents (9 boys, 7 girls) with a mean age of 15 years.
- All affected eyes were myopic, with crowded and tilted optic discs being common (93.75%).
- Hemorrhages resolved spontaneously, with excellent visual outcomes reported.
Conclusions:
- Multilayered optic disc hemorrhages in adolescents are frequently associated with myopia and specific optic disc morphologies.
- These hemorrhages generally have a benign prognosis with spontaneous resolution and good visual recovery.

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...

Photoreceptors and Visual Pathways
8.3K
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,...

Anatomy of the Eyeball
8.4K
The eye is a spherical, hollow structure composed of three tissue layers. The outer layer — the fibrous tunic, comprises the sclera — a white structure — and the cornea, which is transparent. The sclera encompasses some of the ocular surface, most of which is not visible. However, the 'white of the eye' is distinctively visible in humans compared to other species. The cornea, a clear covering at the front of the eye, enables light penetration. The eye's middle...
