Viral conjunctivitis manifests as a fine, diffuse pinkness of the conjunctiva which may be mistaken for iritis, but corroborative signs on microscopy, particularly numerous lymphoid follicles on the tarsal conjunctiva, and sometimes a punctate keratitis are seen. [citation needed]
The conjunctiva is a thin membrane that covers the eye. When an allergen irritates the conjunctiva, common symptoms that occur in the eye include: ocular itching , eyelid swelling, tearing, photophobia , watery discharge, and foreign body sensation (with pain).
Keratoconjunctivitis is a term used to describe inflammation of both the cornea (the clear, front part of the eye) and the conjunctiva (the thin, transparent membrane covering the white part of the eye and lining the inside of the eyelids). This condition can have various causes, and its presentation may vary depending on the underlying factors.
The resulting loose, excess conjunctiva may mechanically irritate the eye and disrupt the tear film and its outflow, leading to dry eye and excess tearing. [2] A correlation may also exist between inflammation in the eye and conjunctivochalasis, though it is unclear whether this correlation is causal.
Conjunctival auto-grafting is a surgical technique that is an effective and safe procedure for pterygium removal. [25] When the pterygium is removed, the tissue that covers the sclera known as the Tenons layer is also removed. Auto-grafting covers the bare sclera with conjunctival tissue that is surgically removed from an area of healthy ...
The plica semilunaris is a small fold of bulbar conjunctiva on the medial canthus of the eye.It functions during movement of the eye, to help maintain tear drainage via the lacrimal lake, and to permit greater rotation of the globe, for without the plica the conjunctiva would attach directly to the eyeball, restricting movement. [1]
Conjunctival epithelium undergoes hyperplasia and sends downward projection into sub-epithelial tissue. Adenoid layer shows marked cellular infiltration by eosinophils, lymphocytes, plasma cells and histiocytes. Fibrous layer show proliferation which later undergoes hyaline changes.
The Bowman's layer (Bowman's membrane, anterior limiting lamina, anterior elastic lamina) is a smooth, acellular, nonregenerating layer, ...
