Summary
Ophthalmoscopic findings in optic disc drusen (ODD) patients help differentiate ODD from papilledema. Key signs include blurred disc edges, raised discs, and abnormal vasculature, aiding accurate diagnosis.
Area of Science:
- Ophthalmology
- Neuro-ophthalmology
Background:
- Optic disc drusen (ODD) are acellular deposits within the optic nerve head.
- Distinguishing ODD from conditions like papilledema is crucial for appropriate patient management.
Purpose of the Study:
- To characterize and compare the ophthalmoscopic manifestations of visible and hidden optic disc drusen (ODD).
- To identify key features that differentiate ODD from papilledema.
Main Methods:
- A study involving 55 patients (100 eyes) with confirmed ODD and 60 controls (100 eyes).
- Analysis of optic nerve features using stereoscopic photography.
- Comparative analysis between visible ODD, hidden ODD, and papilledema.
Main Results:
- Common ophthalmoscopic features in ODD include blurred disc edges (84%), disc elevation (74%), absent cupping (69%), and abnormal vascular branching (81%).
- Statistically significant differences were observed in most parameters when comparing visible and hidden ODD.
- Hidden ODD showed significant differences compared to papilledema in blurred edges, disc elevation, absent cupping, altered color, vascular anomalies, and hemorrhages.
Conclusions:
- Ophthalmoscopic examination reveals distinct features associated with ODD.
- These features are valuable in differentiating ODD from papilledema, preventing misdiagnosis.

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...
01:25Glaucoma: Overview
Glaucoma is an eye condition characterized by increased intraocular pressure that damages the retina and optic nerve, leading to irreversible blindness if left untreated. The human eye has various components, including the cornea, iris, pupil, lens, and optic nerve. Aqueous humor is secreted by the epithelium of the ciliary body in the posterior chamber and flows through the trabecular meshwork and canal of Schlemm, maintaining normal intraocular pressure. The trabecular meshwork and the canal...
01:20Anatomy of the Eyeball
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 layer, the vascular tunic,...
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...
