What is LOCS III?
Conclusion. —The LOCS III is an improved LOCS system for grading slit-lamp and retroillumination images of age-related cataract.
WHAT IS lens opacity?
A cataract is an eye condition where cloudiness, or opacity in the lens, blocks or changes the entry of light, affecting vision.
How many grades of cataract are there?
There are three primary types of cataracts: nuclear sclerotic, cortical, and posterior subcapsular they also have unique symptoms which are discussed below.
WHO published a simplified cataract grading scale?
the World Health Organization
In 2002, the World Health Organization (WHO) published a simplified cataract grading scale [2] .
What is age related nuclear cataract bilateral?
Age-related nuclear cataract is a major cause of blindness. It is characterised by opacification and colouration in the centre of the lens and is accompanied by extensive protein oxidation.
What causes lens opacity?
Proteins and fibers in the lens begin to break down, causing vision to become hazy or cloudy. Some inherited genetic disorders that cause other health problems can increase your risk of cataracts. Cataracts can also be caused by other eye conditions, past eye surgery or medical conditions such as diabetes.
How do you treat corneal opacity?
Treating Corneal Opacity
- Eye drops containing antibiotics, steroids or both.
- Oral medications.
- Phototherapeutic keratectomy (PTK), laser surgery.
- Cornea transplant.
What are Grade 3 cataracts?
Correct! A 3+ cataract. This cataract is so dense that the cortex has liquefied, allowing the nucleus to sink to the bottom of the lens capsule. This special type of very dense cataract is known as a Morgagnian cataract.
What is a Grade 2 cataract?
A 2+ NS cataract. This is a 2+ cataract under dim lighting. You can see that the nucleus is still the same density as the anterior / posterior embryonal zones.
What is subluxation of lens?
In lens subluxation, zonular fibers are broken, and the lens is no longer held securely in place but remains in the pupillary aperture. Lens dislocation occurs following complete disruption of the zonular fibers and displacement of the lens from the pupil. Trauma is the leading cause of lens dislocation.
