DISEASES OF THE UVEA Prof Suhardjo, MD,M Biomed, Ophth
UVEAInflammation UveitisAnatomy classification:Anterior uveitis= iridocyclitisIntermediate uveitisPosterior uveitis=choroiditisPanuveitis=inflammation of the whole uvea
Epidemiology UveitisAdamantiades-Behcets syndrome, and VKH are more common in Japan than in Europe or the United State.Adamantiades-Behcets syndrome seems highly prevalent in Turkey and in China. Tuberculosis remains the main etiology of infectious uveitis in India, Indonesia. Viral uveitis is predominant in the Middle East and in France, followed by Toxoplamosis. Epidemiologic study in northern California: incidence rate 52.4/100,000 person-years.The incidence and prevalence were lowest in the pediatric age groups and highest in those over age 65, women was greater than that man.
Terminology base of: Standardization of Uveitis NomenclatureInactive: grade 0 cells (anterior chamber)Worsening activity: 2-step increase in level of inflammationImproved activity : 2-step decrease or decrease to grade 0Remission: inactive disease for> 3 months after discontinuing all treatments .
Clinical classification:Acute uveitis sudden symptomatic onset and persist for 6 weeks or lessChronic uveitis persists for months or years
Aetiological classificationExogenous uveitis external injury, invasion micro-organisms, other agents to uvea from outsideEndogenous uveitis microorganism, other agents within patient
Endogenous UveitisAssociated with systemic disease (ankylosing spondilitis)Infection bacteria (TB), fungi (candidiasis), viruses (herpes zoster), protozoa (toxoplasma), roundworms (toxocariasis)Idiopathic specific uveitis entities (Fuchs uveitis syndrome)Idiopathic non-spesific uveitis entities
Pathological classificationGranulomatousNon-granulomatous
Clinical Features of UveitisAnterior UveitisSymptomsPhotophobia, pain, redness, decreased vision, lacrimation
Sign: Limbus Ciliary injection
Cornea : Keratic precipitates (KP)Small KP herpes zoster, Fuchs uveitis syndromeMedium KP most types acute and chronic uveitisLarge KP mutton fat granulomatous uveitisFresh KP white and round
Mutton fat KP
Iris nodulesKoeppe nodules Busacca nodules
Koeppe nodulesBusacca nodule
Anterior chamber: Aqueous cellsSign of active inflammationGraded from 0 to +4:5-10 cells = +111-20 cells = +221-50 cells = +3>50 cells = +4
Aqueous flareLeakage of proteins into aqueous humor through damaged iris blood vesselsFaint-just detectable = +1Moderate-iris details clear= +2Marked-iris details hazy= +3Intense-with severe fibrinous exudate= +4
Iris and Pupil : Posterior synechiaeAdhesions between the anterior lens surface and iris
Anterior vitreous cells
Other signs of anterior uveitisHypopyonFibrinPupillary miosisPigment dispersionSynechiaeBand keratopathy (seen in long-standing uveitis)
Intermediate UveitisSymptoms floaters, impairment of visual acuity caused by chronic cystoid macular edema
Sign Cell infiltration of the vitreous (vitritis), with few, if any, cells in the anterior chamber and no focal inflammatory lesion in fundus
Posterior UveitisSymptoms floaters and impairment of visual acuitySignVitreous change cells, flare, opacities and posterior vitreous detachmentChoroiditisRetinitisVasculitisThree main types:Unifocal (toxoplasmosis, onchocerciasis, cysticercus, Masquerade syndromes)Multifocal (ocular histoplasmosis,sypilis, HSV,VZV,CMV,Candida, Sarcoidosis, Masquerade )Geographical (CMV retinitis)
Laboratory and Medical Evaluation Fluorescin angiography; Indocyanine green angiopraphyUSG: vitreous opacities, choroidal thickening, retinal detachment, cyclitic membrane formation.OCT: to measure of uveitic CME.Anterior chamber paracentesis: Goldmann-Witmer coefficient is gold standard for diagnosis of Toxoplasmosis in Europe, PCR is valuable tool in case of viral uveitis or retinitis but less sensitive in diagnosing parasitic infecion.Vitreous biopsyChorioretinal biopsy
Complications of uveitisPosterior synechiae - 30%Cataract -20%Glaucoma due to PAS - 15%Iris atrophy .Band keratopathy - 10%
Therapy for Uveitis Medical : Steroid Immunomodulators: Alkylating agent, antimetabolite, T-lymphocyte modulators,biologic response modifier

Diseases of the LENS
Eyeball
The Lens is a unique structureTransparent: no blood, no nerveHigher protein contentIt continues to grow throughout life. New fiber from just beneath the capsule, while the older fibers are compressed towards the centre of the lens
Ageing changes in the LensIncrease in hardness presbyopiaIncrease in density more dense (nuclear sclerosis), the power of the lens increases lens induced myopia.Increase in size shallowing of the anterior chamberIncrease in opacity: caused by biochemical damage of the delicate protein structure of the lens cells.
LENS DISORDERSAbnormalities of lens shapeColobomaLenticonusSmall lens
Coloboma Coloboma of iris Coloboma of choroid Giant retinal tearOcular associations
LenticonusPosterior Posterior axial bulge Unilateral - usually sporadic Bilateral - familial or in Lowe syndromeAnterior Anterior axial bulge Associated with Alport syndrome
Small lens Small diameter Small diameter and spherical May be familial (dominant)MicrophakiaMicrospherophakia Systemic association - Lowe syndrome Systemic association - Weill-Marchesani syndrome
Cataract =Opacification of the LensGeneral causes :age, diabetes, chronic renal failure, hypoparathyroidism, Downs syndrome, myotonic dystrophy, steroids, episodes of severe dehydration in early life (osmotic shock, severe dehydrationdamage the lens structure).Local causes: trauma, uveitis, glaucoma,myopia, radiation
Cataract backlog in IndonesiaPrevalence of cataract in Indonesia : 1.02%Incidence of cataract in Indonesia: 0.1%Population in Indonesia: 240.000.000Ophthalmologist surgical rate of cataract in Indonesia =200, should be 500 to avoid backlogTotal ophthalmologist in Indonesia : 1500
Why cataract is so much more common in hot climatesEpisodes of severe dehydration in early life (osmotic shock mechanism)Solar radiation:ultraviolet is absorbed by the lens causing damage to the tissue enzymes and protein molecules. Diet. : The poor people have a higher prevalence of cataract than rich people.Heat: glass-blower
Protective factorsAspirin low dose (100 mg) Vitamin CBendazac lysine
Symptoms of cataractDazzling , when opacity in the centre.Multiple images (ghosting, or polyopia) caused by poor refraction.Haloes, caused by opacity in the lens splitRefractive changes, progressive myopia from nuclear sclerosis .
Signs of cataractCortical lens opacities: the most common type of opacities.Nuclear sclerosis: lens hardens at first yellow, then brown, and finally black.Posterior subcapsular lens opacities: less common, often develop in quite young people.

Other causes of cataract - diabetesJuvenile White punctate or snowflake posterior or anterior opacities May mature within few daysAdult Cortical and subcapsular opacities May progress more quickly than in non-diabetics
Other causes of cataract - myotonic dystrophy Myotonic facies Frontal balding 90% of patients after age 20 years Stellate posterior subcapsular opacity No visual problem until age 40 years
Other causes of cataract - atopic dermatitis Cataract develops in 10% of cases between 15-30 years
Bilateral in 70% Frequently becomes mature Anterior subcapsular plaque (shield cataract) Wrinkles in anterior capsule
Causes of traumatic cataractPenetrationConcussion Vossius ring from imprinting of iris pigment Flower-shaped Ionizing radiation Electric shock LightningOther causes
DrugsChlorpromazine Long-acting mioticsOther drugs Amiodarone Busulphan- initially posterior subcapsularSystemic or topical steroids- central, anterior capsular granules
Secondary (complicated) cataract Chronic anterior uveitis High myopiaPosterior subcapsular Hereditary fundus dystrophies Central, anterior subcapsular opacitiesGlaukomflecken Follows acute angle-closure glaucoma
The treatment of cataract is SurgeryIntracapsular extraction : not popular now, impossible to intra ocular implantation.Extracapsular : the posterior capsule and suspensory ligament are left intact, IOL can be implanted.Small Incision Cataract Surgery: the most popular in India.Phacoemulsification : the most popular in the World
Complications of cataractAcute angle-closure glaucoma: a lens which is swollen makes anterior chamber more shallow.Phacolytic uveitis and glaucoma. Fluid lens protein leaks out through the capsule into anterior chamberacute uveitislens protein is ingested by macrophages and these block the anterior chamber angle phacolytic glaucoma

CORNEAL ULCERS
Keratitis Superfisialis, radang epitel/ sub epitel dapat disebabkan oleh infeksi, keracunan, degenerasi, alergi sebagai titik-titik atau pungtata yang merata, infiltrat dibagian atas pada trakoma, dicelah mata pada keratitis sika, atau akibat sinar u v, dibag bawah pada blefarokonjungtivitis stafilokokus
Ulkus Kornea Bakteri : - Sentral ( stafilokok aureus, streptokokus, pneumokok, pseudomonas, moraxella ), yang karena stafilokok biasanya terlokasi, bila karena pneumokok ulkusnya menggaung disertai hipopion, pseudomonas cepat menimbulkan nekrosis dengan eksudat mukopurulen - Marginalis, biasanya karena stafilokok, ada kemungkinan karena reaksi hipersensivitas, ulkus kornea marginalis harus dibedakan dengan ulkus Mooren
- Pemeriksaan laboratorium dilakukan secara rutin pada ulkus kornea, catnya Gram / Giemsa, mediumnya agar darah, agar coklat atau sabouraud, sensitivity tes perlu dilakukanKeratitis Virus Herpes Simpleksa. Keratitis epitelialis, ( keratitis dendritika, keratitis geografika virus menyerang epitel basal
b. Keratitis metaherpetik atau pasca infeksi bentuk linear tidak teratur sehingga hampir sama dengan keratitis geografika, kesembuhan sangat lambat ( 8-12 minggu)c. Keratitis interstitialis virus putih seperti keju (nekrosis), ada radang limbus, harus dibedakan dengan keratitis krn infeksi sekunder atau jamurd. Keratitis diskiformis, kekeruhan bentuk cakram di parenkim kornea yang udem tanpa nekrosis
Keratitis virus Herpes ZosterInfeksi akut yang mengenai ganglion Gaseri, jarang bilateral, sakit saat awal, timbul vesikula pada kulit dahi, kelopak mata sampai ujung hidung, konjungtiva hiperemi, sensitivitas kornea menurunKeratitis JamurPetani, sukar sembuh, infiltrat abu-abu, kadang ada hipopion, gejala inflamasi berat dimulai dengan ulserai superfisial, disertai infiltrat satelit ditempat lain, ulkus meluas sampai endotel, tepi ulkus tidak teratur ( banyak karena Candida )

Clinical Presentation
Determined by :- Clinical category- The infecting organism- Severity- The duration since initiation of the infection
Prominent Symptoms Ocular discomfort/pain Reduced vision
Sign Marked intraocular inflammation with hypopion Chronic iridolytis Granulomatous KP
Clinical Presentation
Acute Onset Post Operative Typically 2-7 Days After SurgeryOcular discomfort and painMarked intraocular inflammation with hypopion * Lid edema, corneal edema, marked conjungtival congestion, fibrin in the AC
Chronic/delayed onset post operative : Months / years after surgery Chronic iridocylitis Granulomatous appearing KP Hypopion
Diagnosis :
- Clinical recognition- Microbiologic Confirmation
Obtaining specimen for microbiologic examination :
- Sample of aqueous :- Local anesthesia- Partial thickness keratotomy- 25 or 27 G needle attached to a tuberculin syringe- Aspirates 0,1 ml of aqueousVitreous specimen : Needle aspiration Vitrectomy biopsy procedure Part of a full therapeutic vitrectomy
Treatment
Goal: Retention of useful vision Consists of : Intensive antibiotic administrationThe use of anti-inflammatory therapyVitrectomy + antibiotic + anti-inflammatory therapy
Antibiotic Treatment :
Delivery: - Intraocular injection - Systemic administration - Periocular injection - Topical ApplicationAntibiotic Agent
Intravitreal injection of antibiotics
- Achieve high intraocular concentration- Should be performed early (at the time of diagnostic sampling)- Recommended antibiotic agent : * Vancomycin (1 mg in 0,1 ml) * Amikacin 0,4 mg/0,1 ml/gentamycin 0,1 mg in 0,1 cc- Repeated injection is not recommended
