Xanthelasma in the form of XP can be diagnosed from clinical impression, although in some cases it may need to be distinguished (differential diagnosis) from other conditions, especially necrobiotic xanthogranuloma, syringoma, palpebral sarcoidosis, sebaceous hyperplasia, Erdheim–Chester disease, lipoid proteinosis (Urbach–Wiethe disease), and the syndrome of adult-onset asthma and ...
BCEM, also referred to as conjunctival hypermelanosis, complexion-associated melanosis, or racial melanosis, is a non-cancerous lesion of the conjunctiva that is more commonly found in dark-skinned individuals (over 90% of lesions are found in black persons and around 5% in white persons). [1]
Exenteration - Removal of the eye, all orbital contents, which can involve the eyelids as well. A special prosthesis is made to cover the defect and improve appearance. Iridectomy - Removal of the affected piece of the iris; Choroidectomy - Removal of the choroid layer (the vascular tissue sandwiched between the sclera and the retina)
Evisceration – removal of the iris, lens, and internal eye contents, but with the sclera and attached extraocular muscles left behind; Enucleation of the eye – removal of the eyeball, but with the eyelids and adjacent structures of the eye socket remaining. An intraocular tumor excision requires an enucleation, not an evisceration.
Redness of the sclera and conjunctiva, sometimes changing to a purple hue; Severe ocular pain, which may radiate to the temple or jaw. The pain is often described as deep or boring.

The sclera's blood vessels are mainly on the surface. Along with the vessels of the conjunctiva (which is a thin layer covering the sclera), those in the episclera render the inflamed eye bright red. [6] In many vertebrates, the sclera is reinforced with plates of cartilage or bone, together forming a circular structure called the sclerotic ring.
On a hot and humid night in Vietnam, a scaly creature perched on a rock in the middle of a forest. The animal had yellow eyelids and a mosaic-like pattern. It turned out to be a new species.
