OBJECTIVES:
To raise the awareness among students about World and Indonesian blindnessproblems and its prevention strategies

Blindness problem:
- patient : time ability work chance
- patient’s relatives: time to care cost
- goverment : facilities for blinds people

Aspect of vision loss:
1. Organ system: - physical and anatomical changes diseases, disorders2. Organ system: - visual function changes impairment3. Whole person: - ability activities of daily living ability / disability4. Whole person: - social economic consequences handicap quality of life
Vision (visus) measured : with Snellen chart

THE WORLD BLINDNESS: ( WHO Fact sheet, 2000 )
- 185 million : impaired vision (visus less than 6/18) - 45 million : blind - 95% under developed country - 80% avoidable ( cataract nearly half of the world’s vision loss , and 80% may die before they have a chance for surgery in 1995 low of cataract surgical rate )

VISION IS IMPORTANT EYE HEALTH CARE IS PRIORITY:
1.Epidemiological aspect: - eye diseases: caused blindness a long periode - eye disease: affect all ages, easy to spread, affect in wide area - vision : important in the technological era - blindness prevalence: high
2.Technological aspect: - eye health program can be integrate to other health program

CATARACT:Cataract is lens opacityMost common cause of blindness worldwide ( 17 million ) 2020 estimated to be 40 millionSurgery: effective & efficientMajority of cases: old ageRisk factors: genetic, cigarette smoking,ultra violet exposure,nutrition,diabetic,alcohol use,steroid use
GLAUCOMAGlaucoma: Primary angle closure Primary open anglecommon on > 40 years, women > manRisk factors: anatomic predisposition (shallowing anterior chamber, smaller corneal diameter) myop, hypermetropPrevention: screening

TRACHOMA:
- Infectious eye disease caused by: chlamydia trachomatis - WHO: to cause 15% world blindness - Risk factors : poor community, flies, ethnic, younger age - Trachoma prevention: primary : hygiene secondary : antibiotica tertiary : surgery WHO: strategies of prevention & treatment SAFE : S surgery A antibiotica F face cleanliness E environtment

MICROBIAL KERATITIS (corneal infection)Risk factors : corneal trauma warm & humid places farmer , stone / brick workerPrevention: - screening - antibiotic & anti fungal for corneal abrasion
REFRACTIVE ERROR:Large proportion : productive ageMost common responsible for visual impairment: myopiaRisk factors: genetic, near work,intellegence, prematurePrevention: spectacle, contact lens, surgery

VITAMINE A DEFFICIENCY:
* 5 - 10 children develop xerophthalmia / year 500.000 blind* Risk factors: geographic, socio culture, measles* Clinical classification: Night blindness ( XN ) Conjunctival Sign ( XI A & XI B ) Xerosis & Bitot’s spot Corneal Sign ( X2, X3A, X3B) Corneal Scar (XS)* Prevention: Periodic vit A supplementation Fortification of food stuff Vit A rich food
