Instillation of pure thioglycolic acid iato the eyes of a rabbit resulted iu severe pain, severe conjunctival inflammation, dense corneal opacity, and severe idtis. These effects had not improved at the end of 14 d after exposure. Washing immediately after exposure did not modify the response (23). 

Rabbit Eye Irritation. Instillation of the chlorodibenzodioxins into the conjunctival sac caused slight, transient pain and conjunctival inflammation, initially. Treatment with 2,3,7,8-TCDD was associated with delayed conjunctival chemosis 13-22 days later. By day 27, the chemosis had subsided, but the rim of the eyelid was thickened and encrusted. 

Conjunctival calcifications are associated with a gritty sensation in the eyes, redness, and inflammation. 

Signs and Symptoms Sudden onset of fever, headache, conjunctival congestion, generalized aches, swollen, painful lymph nodes, and inflammation of the lung tissue (pneumonitis). A dull red to dark purple maculopapular rash appears first on the trunk then spreads to the arms and legs. Can progress to pulmonary, encephalitic, and/or cardiac complications. 

The effects of the liquid in the eyes of rabbits are immediate signs of moderate discomfort with mild conjunctivitis but no significant corneal damage. In one human incident of a splash in the eye, there was reversible conjunctival inflammation. The liquid produces no significant irritant action on the skin. 

Paraquat is commonly combined in commercial herbicides with diquat, a related compound in several instances, the commercial preparations splashed in the eyes have caused serious injury. " Effects have been loss of corneal and conjunctival epithelium, mild iritis, and residual corneal scarring. In contrast, in the eye of a rabbit, one drop of a 50% aqueous solution of pure paraquat caused slow development of mild conjunctival inflammation and pure diquat proved even less irritating. Presumably, the surfactants present in the commercial preparations are responsible for the severe eye injuries to humans. ... 

Suspension - Shake well before using. Instill 1 or 2 drops in the conjunctival sac(s). In severe disease, drops may be used hourly, being tapered to discontinuation as inflammation subsides. In mild disease, drops may be used up to 4 to 6 times daily. 

Postoperative inflammation Apply 1 to 2 drops into the conjunctival sac of the operated eye(s) 4 times daily beginning 24 hours after surgery and continuing throughout the first 2 weeks of the postoperative period. MEDRYSONE Shake well before using. Instill 1 drop into the conjunctival sac up to every 4 hours. 

Solutions - Depending on the severity of inflammation, instill 1 or 2 drops of solution into the conjunctival sac up to every hour during the day and every 2 hours during the night as necessary as initial therapy. 

Colic. Pertaining to the colon acute abdominal pain characteristically, intermittent visceral pain with fluctuations corresponding to smooth muscle peristalsis. Conjunctivitis. Inflammation of the delicate membrane that lines the eyelids and covers the exposed surface of the sclera (conjunctiva), generally consisting of conjunctival hyperemia associated with a discharge.

Acute injuries of the eyes, primarily from effects of blast and missiles, may occur from tear-gas weapons, such as pen guns. The lnmeulate effects of these Injuries include swelling and edema of the lids, with penetration of skin, conjunctiva, cornea, sclera, or globe by gunpowder and CN conjunctival ischemia and chemosls corneal edema, erosion, Inflammation, or ulceration and focal hemorrhage. 13,20... 

Rabbit (albino) once Ocular 0.1 mL (severe conjunctival inflammation with serous and hemorrhagic exudates severe/ moderate corneal injury) Haskell Laboratory 1961... 

HDI has been demonstrated to be an ocular irritant in laboratory animals in several studies. HDI (0.1 mL, undiluted) was instilled into both eyes of a male albino rabbit. One eye was washed 20 seconds later with large amounts of water, whereas the other eye was not washed. The animal was sacrificed 8 days after treatment. Initially, the exposure caused severe conjunctival inflammation accompanied by serous and hemorrhagic exudates of both eyes, with severe (unwashed eye) or moderate (washed eye) corneal injury. When the rabbit was sacrificed 8 days after treatment, the corneas of both eyes appeared dull and the eyelids were inflamed and still showed the hemorrhagic and serous exudates. Healed eomeal lesions... 

An ophthalmic preparation seems to be efficacious for conjunctival inflammation and to reduce pain after traumatic corneal abrasion. Gingival inflammation is reduced after administration of indomethacin oral rinse. Epidural injections produce a degree of pain relief similar to that achieved with methylprednisolone in postlaminectomy syndrome. 

This ischemia can be trivial, limited to the breaking of the blood flux in only one vessel and not easy to detect because of being hidden in a spread conjunctival hyperemia. The conjunctival hyperemia differs from ischemia. The conjunctival hyperemia is a dilatation of the conjunctival and episcleral vessels. It signihes an inflammation as a reaction to the irritation caused by the chemical bum. It is not a sign of the gravity of the chemical bum (Fig. 7.4). 

The ocular adverse effects of latanoprost include conjunctival hyperemia, iris pigmentation, periocular skin color changes, anterior uveitis, and cystoid macular edema in pseudophakic patients (77,78). H. simplex dendritic keratitis has been reported after treatment with latanoprost (79). In patients with uveitic glaucoma, latanoprost can cause increased intraocular pressure and recurrence of inflammation (80). 

Indomethacin enjoys the usual indications for use in rheumatic conditions and is particularly popular for gout and ankylosing spondylitis. In addition, it has been used to treat patent ductus arteriosus. Indomethacin has been tried in numerous small or uncontrolled trials for many conditions, including Sweet s syndrome, juvenile rheumatoid arthritis, pleurisy, nephrotic syndrome, diabetes insipidus, urticarial vasculitis, postepisiotomy pain, and prophylaxis of heterotopic ossification in arthroplasty, and many others. An ophthalmic preparation seems to be efficacious for conjunctival inflammation (alone and in combination with gentamicin) to reduce pain after traumatic corneal abrasion. Gingival inflammation is reduced after administration of indomethacin oral rinse. Epidural injections produce a degree of pain relief similar to that achieved with methylprednisolone in postlaminectomy syndrome. 

Ocular Effects. A single application of 2,000 g 2,7-DCDD, 2,3,7,8-TCDD, mixed HxCDD, or OCDD into the conjunctival sac of rabbits caused transient pain and conjunctival inflammation (Schwetz et al. 1973). Delayed conjunctival chemosis was observed with 2,3,7,8-TCDD. None of the CDDs caused comeal injury or iritis. 

Causative agent, Chlamydia trachoma grows in conjunctival ceils causing chronic inflammation, scarring, and eventual blindness. 

The original beneficial properties of CsA for ocnlar snrface inflammation were first determined in dogs with dry eye. Conjunctival biopsies taken from dogs with spontaneons chronic idiopathic dry eye contained nnmerons CD3-I-T cells.The lacrimal acinar and conjnnc-tiva epithelial cells of dogs with dry eye nnderwent apoptosis, whereas the infiltrating inflammatory CD4-I- T cells... 

A significant positive correlation has been observed between the levels of inflammatory cytokines in the conjunctival epithelium and the severity of ocular irritation symptoms and corneal fluorescein staining. The inflammatory cytokines and other inflammatory mediators also correlate positively to severity of conjimctival squamous metaplasia in Sjogren patients. These proin-flammatory cytokines also have been implicated in regulation of epithelial mucin expression, with several studies suggesting inflammation is central to the pathogenesis of meibomian gland dysfunction as well. 

Several distinct clinical signs herald conjunctival inflammation. However, the actual presentation depends on the nature of the causative agent, the time course, and any preexisting disease. Conjimctival tissue may be exposed to antigens, pathogens, toxins, or irritants through airborne transmission direct contact (hand to eye, person to person, or from contaminated instruments or surfeces) and inadvertent sexual transmission. 

Systemic disorders may also manifest with conjunctival inflammation. Acute or chronic conjunctivitis may present with any of five signs of conjunctival inflammation chemosis, hyperemia, discharge or exudate, follicles, and papillae (Table 25-1). Specific patterns of inflammation may be helpful in diagnosis of the underlying cause.
