Is Vossius ring permanent?
A Vossius ring is asymptomatic and generally will improve or resolve with time.
What is rosette cataract?
Rosette cataract is a type of traumatic cataract. Traumatic cataract is the clouding of the lens that occurs either by blunt trauma to the head or eye region or penetrating ocular trauma resulting in the disruption of the lens fibers. This in turn prevents a clear image from forming on the retina.
What is traumatic cataract?
Traumatic cataract is a clouding of the lens that may occur after either blunt or penetrating ocular trauma that disrupts the lens fibers. Most traumatic cataracts are intumescent, but their type and clinical course depend on trauma mechanism and the integrity of the capsular bag.
What is concussion cataract?
Traumatic cataract is clouding of the lens and eyes that may occur after either blunt or penetrating ocular trauma that disrupts and damages the lens fibers. Most of the traumatic cataracts lead to eye lens swelling, but the type and clinical course depends on trauma and the integrity of the capsular bag.
Why does my iris jiggle?
Iridodonesis is a condition in which the iris (coloured part of the eye) vibrates during eye movements. Upon moving the eye rapidly, the iris can appear to ‘dance’, or ‘tremble’ (tremulousness). This occurs when the lens becomes partially detached (lens subluxation) from its suspensory ligaments.
Which type of cataract is caused by trauma?
Traumatic cataracts. Traumatic cataracts can occur as a result of a sharp penetrating injury to the lens capsule and/or lens, or a blunt concussive force.
What are the symptoms of a secondary cataract?
The most common symptoms of a secondary cataract are a reduction in visual acuity months or years after cataract surgery, which impedes both far and near vision; in addition to glare from the sun, car headlights at night and a reduction in the perception of colours.
How common is persistent fetal vasculature?
In normal development, fetal vasculature regresses without complications; however, in 95% of premature infants and 3% of full term infants, fetal vasculature persists and can result in a spectrum of disorders.
What is persistent hyaloid?
Persistent hyaloid artery represents a remnant of the hyaloid vascular system. This occasionally runs from the disc to the lens; more commonly an anterior remnant gives a Mittendorf dot on the posterior lens surface or a posterior remnant gives a Bergmeister’s papilla over the disc.
