Anterior segment ocular computerized tomography showing a thickened sclera and episclera
with hyporeflective areas (asterisks) before treatment (c).
Within the eyes, neoplastic lymphocytes had expanded and effaced the iris leaflets, ciliary body, and the choroid (Fig 2) infiltrating the sclera and episclera
near the optic nerve, with additional multifocal regions of conjunctival involvement.
There is usually an area of inflammation of the conjunctiva, episclera
or sclera adjacent to the area of crescent-shaped peripheral corneal ulceration and thinning.
As the sclera was absent due to penetrating sclerectomy, the fibroblasts migrated from the choroid and the episclera
(Figure 2B) to the choroidal and conjunctival faces, respectively, through a fibrin net.
It begins with a summary chapter readers can use as a refresher or background, then proceeds to describe the anatomy and physiology of the bony orbit, eyebrows, eyelids, the lacrimal system, extraocular muscles and the globe, conjunctiva, episclera
, sclera, cornea, anterior and posterior chambers, the posterior segment, visual pathways, nerve and vascular supply, and lymphatics.
Poor prognostic indicators of ocular lesions include tumor thickness, pagetoid spread, and involvement of the cornea, episclera
, palpebral conjunctiva, or fornix.
who made an attempt to investigate the structural features of the posterior part of the episclera
and the Tenon's fascia in patients with high myopia .
Cornea and episclera
are tissues with enhanced susceptibility to systemic inflammatory diseases, due to distinct local characteristics such as high vascular network of the conjunctiva and episclera
, collagen riche-environment, and high number of Langerhans cells, immunoglobulin M (IgM), and complement C1, which favours immune complex formation .
Bleb failure can occur after trabeculectomy for various reasons, but the most common cause is fibrotic changes in the conjunctiva and episclera
. (2,3,4) Therefore, modulating wound healing has particular importance in trabeculectomy.
The graft was sutured using 8-0 vicryl interrupted sutures with the bites incorporating the episclera
at limbal side.
(1) The episclera
is a fibroelastic structure covering the sclera and is formed of two layers loosely joined together by connecting fibres.
Tenon's capsule is dissected from the episclera
. The body of AGV is placed 8-10 mm from the limbus and sutured with 10-0 nylon sutures to the sclera.
