BLINDNESS AND ITS PROBLEMS

by : dr. Nunuk Maria Ulfah Sp M, M.Kes

OBJECTIVES:

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

INTRODUCTION Vision is important: - life survival - correlate to quality of lifes ability,

intelegency, productivity, social economic

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

Vision and blindness:

Criteria Corrected Bilateral Vision Minimal Maximal 1 6/60 6/18 2 3/60 6/60 3 1/60 3/60 4 Light perception 1/60 5 No light perception_______________________________________________ Criteria : 3,4,5 : Blindness

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 )

WORLD BLINDNESS – CAUSES OF BLINDNESS:

Trachoma Xerophthalmia Glaucoma Ocular trauma Cataract Onchocerciasis

INDONESIAN BLINDNESS -- CAUSES OF BLINDNESS Cataract Glaucoma Refraction anomaly Corneal diseases Retinal Diseases

INDONESIAN BLINDNESS:

Causes of blindness survey 1982 survey 1996__________________________________________

1. Cataract 0.76 % 1.02 %2. Glaucoma 0.10 % 0.16 % 3. Retinal diseases 0.03 % 0.09 %4. Refraction 0.06 % 0.11 %5. Corneal diseases 0.13 % 0.06 %

BLINDNESS IN ASIA:

Indonesia ------- 1.5 % India ------ 0.6 % Bangladesh --------1 % Ceylon --- 0.5 % Myanmar ---------0.9 % South Korea ------ 0.4 % Bhutan --------- 0.8 % Thailand --- 0.3 %

BLINDNESS PROBLEMS:

< 0.5% ---- Clinical problems 0.5 % - 1 % ---- Community health problems > 1 % ---- Social problems

INDONESIAN BLINDNESS PEOPLES:

Number of blindness 1.5 % .......... 3,000,000 peoples 52 % cataract .........................1,560,000 ,, 9.5 % refraction .......................... 285,000 ,, 13.4 % glaucoma .......................... 402,000 ,, 8.5 % retinal diseases .................... 255,000 ,, 6.4 % corneal diseases ................. 192,000 ,, 10.2 % others .......................... 306,000 ,,

PREVALENCE OF EYE MORBIDITY ( THE BIG TEN ):

Refraction : 22.1 % Pterygium : 13.9 % Cataract : 7.3 % Conjunctivitis : 1.4 % Corneal disease : 0.4 % Glaucoma : 0.4 % Strabismus : 0.3 % Hordeolum : 0.3 % Blepharitis : 0.3 % Papil Atrophy : 0.2 %

INDONESIAN HEALTH CARE:

‘’Indonesia Sehat 2010” ..... Targets:

• To increase the expectancy of life• To increase nutritional status• To decrease mother and child mortality• To decrease disease morbidity• To decrease fisical deformities

VISION 2020 IAPB (International Agency for the prevention of Blindness)

1- The right to sight (every people has right to have optimal vision) global initiative to eliminate avoidable blindness by the year 2020.

2- Target campaign in avoidable blindness: cataract, refractive error and low vision, trachoma, onchocerciasis, glaucoma and diabetic retinopathy

3- Strategies: cost effective close collaboration among partners global awareness community level

4- Program: Disease prevention & control Personel training Strengthening eye infra structure Apropriate and affordable technology Mobilization of resources

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

3. Environmental aspect: - health environment correlate with eye diseases

4. Peoples behaviour aspect: Indonesian survey: 79.1 % eyes patient did not look for a treatment Among them who looked for a treatment: 6.7 % used self treatment, 5.4 % went to the hospital, 2.8 % went to the health centre

VARIOUS INTERVENTIONS FOR BLINDNESS PEOPLES: The organ The person Physical &

Anatomical Changes

Functional Impairment

Ability to ADL

Soc.Ec.Consequences

Medical, surgical

Visual aid, devices

Education & training

INDONESIAN EYE HEALTH CARE PROGRAM:

1. Aim: Reduce blindness Reduce prevalence of eye diseases Raise peoples awareness Promote eye health program Promote strategic aliances

2. Policy: Dissemination and advocation of eye health program Promote manpowers quality Promote community and NGOs partisipation Develop infra structure

3. Target: Under five, school ages, productive ages, old peoples Health staffs Professionals NGOs Government

4. Strategies: Advocation / promotion Eye health care: Primary eye health care ( PEC ) --- health centre Secondary health care ( SEC ) --- district hospital Tertiary health care ( TEC ) ---- province hospital Increase of eye specialist production Education – training Research NGOs partnership Develope Information system

PRIMARY EYE CARE: Area : Health centre Services : curative policlinic, admission Refferal TEC & PEC Report & recording Health education Community partisipation

SECONDARY EYE CARE: Area : District hospital Service : PEC curative + standard & simple surgery Refferal PEC & TEC Report & recording Health education

TERTIARY EYE CARE:

Area : Province hospital Services : SEC curative + hi tech surgery Refferal SEC & PEC Report & recording Health education Research

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

DIABETIC RETINOPATHY:

- Leading cause of blindness in USA & UK among 20- 74 years old - Risk factors: older age, family history of diabetes, obesity
