The bulbar conjunctiva and anterior episclera are nourished by vessels from the anterior and long posterior ciliary arteries [18], and the limbal conjunctiva is supplied by superficial arcades of the anterior ciliary vessels [19].
It is usually fixed to the cornea or the episclera using 10-0 nylon sutures (Figure 5e).
They adhere generally to the episclera and the conjunctiva and might involve the muscle.[sup][1],[2] Previous report stated that females account for 69% of cases, the right eye for 76%, and superotemporal localization for 74% of cases.[sup][3] According to PubMed-based research, 76 cases of epibulbar osseous choristoma were reported up to 2016.
Anterior segment ocular computerized tomography (OCT) demonstrated a thickened episclera and sclera with hyporeflective areas representing fluid in the region, confirming the diagnosis of scleritis (Figures 1(a) and 1(c)).
Neoplastic lymphocytes effaced the iris, ciliary body, and the choroid of the eyes, and neoplastic lymphocytes were attached to the corneal endothelium and infiltrated the sclera, episclera, and conjunctivae.
The duration of cryotherapy was controlled depending on the location of lesion-the ice ball extending 2 mm for conjunctiva, 1 mm for episclera and 0.5 mm for the cornea.
According to Binder, (24) "the gas from the evaporated cornea escapes into the episclera over the ciliary body and creates irritation through the ciliary body"
The sclera and the episclera may be involved in addition to the cornea, and damaging forms of keratitis (e.g., punctata epithelial, dendritic, nummular, or neurotrophic) may appear.
Mitomycin C (MMC) prevents pterygium recurrence by its ability to inhibit fibroblast proliferation at the level of the episclera. It is an antineoplastic antibiotic agent isolated from the fermentation filtrate of Streptomyces caespitosus.
Episcleritis is a self-limiting, benign inflammation of the episclera. Ocular redness with slight tenderness typically lasts days to weeks and resolves spontaneously in most cases.
These inflammatory cells, originated from the uvea and the adjacent episclera, were observed in the choroidal and conjunctival faces of the graft.
Artifactual seeding is composed of small groups of tumor cells, usually with many necrotic cells present inside natural spaces of the eye (eg, vascular choroidal and suprachoroidal space, anterior chamber, or subarachnoid space of the optic nerve), spaces created by sectioning artifacts, and/or on the surfaces of the eye (episclera, over meninges of optic nerve, and soft tissues attached to optic nerve).
