Anterior Uveitis • Anterior uveitis refers to inflammation of the iris and/or ciliary body and • Usually presents with a painful, red eye. • Patients often c/o decreased vision and a watery discharge. Anterior Uveitis • Photophobia is 2’ to spasm of inflamed iris and ciliary muscles. • Visual acuity varies depending on the severity of the inflammation. Anterior Uveitis • The pupil is often miosed • if untreated, the pupil margin may adhere to the lens due to the formation of posterior synechiae. Anterior Uveitis • Corneal precipitates may occur on the endothelium • hypopion (pus in the anterior chamber) may be present in severe cases. Treatment • Dilating drops – relieve ocular discomfort by reducing ciliary muscle spasm – prevent the formation of posterior synechiae. • Topical corticosteroid drops to treat the inflammation • Periocular steroid injections or even systemic corticosteroids may be required in more severe cases. Case 2 • • • • 30 y.o lady 5 day Hx of FB sensation and redness Lt eye. c/o reduced vision and watery No previous eye Hx • O/E VA is 6/9 • Mild diffuse conj injection. • A whitish area seen in the pupillary zone • What would you do next? • Instillation of 2% fluorescein shows a branching ulcer on the lateral side of the cornea. • What is the Dx? Herpes simplex Keratitis Dendritic ulcer Confined to epithelium but deeper tissues may become involved. Stained with fluorescein and rose bengal Rx topical aciclovir Dendritic ulcer Geographic Epithelial keratitis Dendritic ulcers coalesce and enlarge to form this larger ulcer. Can occur as a result of inappropriate steroid use. Do not treat a red eye with steroid unless HSK is ruled out. Case 3 • A 9 y.o. boy c/o sever itching in both eyes. • his mother says that he is constantly rubbing his eyes. • The eyes water a lot and bright light hurts them. • Not sticky, no discharge. • He is currently on treatment for asthma. • O/E , his VA is 6/9 in both eyes • He is very photophobic. • His eyelids are red. • The conjunctiva is mildly injected. • His corneas are clear and do not stain with fluorescein. • What do you do next? • Upon everting his upper eyelids, you notice several raised, fleshy lesions on the conjunctival surface of the upper lids. • What is the diagnosis? Vernal keratoconjunctivitis • Vernal keratoconjunctivitis – most commonly occurs in young boys – often have a history of atopy. • Symptoms include – severe, chronic ocular itching – photophobia, – blepharospasm, – mucoid/watery discharge – blurred vision also occur frequently. Vernal keratoconjunctivitis • Signs include giant papillae under the upper eyelid • they have a typical cobblestone appearance. Vernal keratoconjunctivitis • Limbitis • a fleshy, gelatinous ring around the limbus, • contains whitish spots called Trantas dots. Treatment • Mild cases respond to: – topical antihistamines and artificial tear drops – topical mast cell stabilisers – oral antihistamines is often required in cases of moderate severity. • Severe cases frequently require: – short courses of topical corticosteroids, such as fluorometholone or dexamethasone – intraocular pressure need to be monitored. • In very severe cases – topical immunomodulatory drugs, such as cyclosporine or tacrolimus, may be needed to control the inflammation. Case 4 • A 32 y.o. female c/o redness and increasing pain in her left eye x 3/7. • The eye is painful to touch • The pain has woken her from sleep over the last two nights. • Eye is a little watery but there is no significant discharge • visual acuity has not changed. • O/E VA is 6/6 and her eyelids are normal. • large area of redness, temporal to the cornea. • The eye is very tender to touch. • looking at the eye in natural daylight, the underlying sclera has a purplish hue. • The rest of the examination is unremarkable. • What is the likely Dx? Scleritis • Scleritis may be either diffuse or nodular. • Pain is a prominent feature. • Often wakes the patient from sleep during the night. • Visual acuity is often not affected in the early stages. Scleritis Etiology: Collagen vascular disease RA, SLE, gout, syphilis Complications: Peripheral ulcerative keratitis with corneal perforation Secondary glaucoma Scleral melting and perforation Exudative retinal detachment Treatment • Scleritis often responds adequately to oral NSAIDs. • > 50% of patients with scleritis have an associated systemic disease. • They require specialist referral for systemic workup • May need potent immunosuppressive therapy.
