Keratic precipitate (KP) is an inflammatory cellular deposit seen on corneal endothelium. Acute KPs are white and round in shape whereas old KPs are faded and irregular in shape. Mutton-fat KPs are large in shape and are greasy-white in color and are formed from macrophages and epithelioid cells. They are indicative of inflammatory disease. [1]
Arcus senilis deposits tend to start at 6 and 12 o'clock and progress until becoming completely circumferential. The thin clear section separating the arcus from the limbus is known as the clear interval of Vogt. Specialty: Ophthalmology Symptoms: Opaque ring in the peripheral cornea: Causes: Normal aging, Hyperlipidemia: Differential diagnosis
It is seen as a yellow-white deposit on the conjunctiva adjacent to the limbus (the junction between the cornea and sclera). [3] (It is to be distinguished clinically from a pterygium, which is a wedge shaped area of fibrosis that may grow onto the cornea.) A pinguecula usually does not cause any symptoms.
The corneal limbus (Latin: corneal border) is the border between the cornea and the sclera (the white of the eye). The corneal surface is one of the body's most specialized structures, undergoing continuous cellular renewal and regeneration. [1] It contains limbal stem cells in its palisades of Vogt.
inflamed pinguecula [10] – a yellow-white deposit close to the junction between the cornea and sclera, on the conjunctiva. It is most prevalent in tropical climates with much UV exposure. Although harmless, it can occasionally become inflamed. tiredness
The white fluffy material is seen in many tissues both ocular and extraocular, [8] such as in the anterior chamber structures, [4] [5] trabecular meshwork, central disc, zonular fibres, anterior hyaloid membrane, pupillary and anterior iris, trabecula, and occasionally the cornea. [9] [10] The flakes are widespread. [8]
Corneal dystrophy may not significantly affect vision in the early stages. However, it does require proper evaluation and treatment for restoration of optimal vision. Corneal dystrophies usually manifest themselves during the first or second decade but sometimes later. It appears as grayish white lines, circles, or clouding of the cornea ...
Lattice corneal dystrophy type II. Black and white light micrograph showing deposits of amyloid in cornea. Congo red stain. Diagram depicting gelsolin and the amyloid protein derived from it because of mutations in codon. Lattice corneal dystrophy has three types: [3] type I: with no systemic association.
