Outline Community Ophthalmology ?/PEC Burden of various blindness causingdisorders National Programme for control of Blindness. Right to Sight: Vision 2020.
Community ophthalmology Synonyms = Public health ophthalmology = Preventive eye care (PEC) = Preventive Ophthalmology
Community ophthalmology The Aim : To provide the essential, accessible Quality Ophthalmologic services to the community at affordable cost to .
Principles of Community Ophthalmology Based on principles of Primary health care.
Three-pronged strategy of Community Ophthalmology
Fact finding surveys Research Screening Clinical care Health education Referral Follow up Improvement of basic needs . Activities in Community Ophthalmology
Activity Primary prevention Health Education about Common Ophthalmic diseases & Specific Protection. Secondary prevention Identify and treat in the community Primary health care workers Volunteers(Trained) P. H. Workers General physicians Community Ophthalmologist. Person Community /SC Community /PHC Place
Activity Identify and refer for Treatment Specialized eye care Rehabilitation PEC Workers Optometrists Ophthalmologist. Ophthalmologist VR Surgeon Person District Hospitals Medical colleges, ROI, Super specaility services Place
Delivery of eye care- model Primary Health center District hospitals National teaching Hospitals,Superspeciality hospitals Primary eye care Secondary eye care Tertiary eye care
Primary eye care workers = Survey – Detection – Referral – Workers SDRW. What is a SDRW ? Is the most important person of this whole programme . Attached to the community ophthalmology center.
Duties of SDRW Screen, Sensitize and inform patients and families on their problems. Refer for treatment provide simple medication
What is the training a SDRW should have before going to the field ? Basic knowledge on structure and function of the eye Recording of visual acuity. Recognize a normal healthy eye & common eye problems.
What is the training a SDRW should have before going to the field ? Ability to identify Cataract / Squint / Refractive errors / Eye injuries / Infections / FB. Identify corneal scars / differentiate from cataract.
What is the training a SDRW should have before going to the field ? Explanations about common eye problems - To explain it to the people To recognize and refer serious eye injuries
What is the training a SDRW should have before going to the field ? Activities and responsibilities of the eye unit and staff. How to meet with a family (communication skills)
What is the training a SDRW should have before going to the field ? During training they should witness at least three cataract surgeries - Taken visual acuity of 10 patient - Perform pinhole test.
Village level eye care provider would be responsible for village eye care activities. ASHA , Anganwadi Workers , Health Workers would be key persons responsible for household survey maintenance of Village Blind Register
WHO Guidelines for primary eye care Conditions to be recognized and treated by a trained primary eye care worker Conjunctivitis and lid infections - Acute conjunctivitis - Ophthalmia neonatorum - Trachoma - Allergic & Irritative conjunctivitis Blinding Malnutrition -
Conditions to be recognized and referred after treatment has been initiated. Corneal ulcers Lacerating or perforating injuries of the eye ball Lid lacerations Entropion / Trichiasis Burns - Chemical - Thermal
Conditions that should be recognized and referred for treatment. Painful red eye with visual loss Cataract Visual loss < 6/18 in either eye
Burden of Blindness
Definition of blindness under NPCB (ref NPCB website) Blindness is defined under following headings: Simple Definition : Inability of a person to count fingers from a distance of 6 meters or 20 feet. Technical Definition : Vision 6/60 or less with the best possible spectacle correction or Diminution of field vision to 20° or less in better eye.
4 levels of visual function, ICD-10 (Update and Revision 2006): Normal vision Moderate visual impairment Severe visual impairment Blindness. LOW VISION VISUAL IMPAIREMENT
World Wide
Globally Causes of visual impairment
Burden of blindness in India Of the total estimated 45 million blind persons ( best corrected visual acuity < 3/60) in the world , 7 million are in India. India is committed to reduce the burden of avoidable blindness by the year 2020 by adopting strategies advocated for Vision 2020- The Right to Sight. Due to the large population base and increased life expectancy, the number of blind particularly due to age-related disorders like cataract, is expected to increase
Trend of blindness In India
Main causes of blindness In India (Ref NPCB 2015)
Cataract Major cause of blindness in the world. Estimated 16-20 million people are bilaterally blind from cataract The cataract surgical rate is a quantifiable measure of the delivery of cataract services. It is the number of cataract operations per million population per year. Aim (Vision 2020) Elimination of cataract blindness (person with vision less than 3/60 in both eyes.)
The prevalence of unoperated cataract in people aged ≥60 was 58% in north India (95% CI, 56–60) and 53% (95% CI, 51–55) in south India ( P = 0.01) Vashist P, Talwar B, Gogoi M, et al. Prevalence of Cataract in an Older Population in India: The India Study of Age-related Eye Disease. Ophthalmology . 2011;118(2-19):272-278.e2. doi:10.1016/j.ophtha.2010.05.020.
Trachoma : Burden Estimated 146 million people have the active infection with the microorganism Chlamydia trachomatis . There are approximately 10.6 million adults with in turned eyelashes ( T richiasis / entropion ), for which eyelid surgery is needed to prevent blindness. An estimated 5.9 million adults are blind from corneal scarring due to trachoma. Trachoma is the second cause of blindness in sub-Saharan Africa, China and the Middle-Eastern countries
Onchocerciasis : Disease Burden Onchocerciasis (also called river blindness or filariasis ) is a disease caused by the nematode (worm) Onchocerca volvulus . An estimated 17 million people are infected with onchocerciasis . 0.3-0.6 million are blind from the disease. Endemic in 30 countries of Africa and occurs in a few foci in six Latin American countries and in Yemen
Burden Countries Ref: www.who.int /blindness/partnerships/ onchocerciasis_disease_information /en/, accessed May 5, 2014. - See more at: http://www.kidsnewtocanada.ca/conditions/onchocerciasis#sthash.WOAYZ1BZ.dpuf
Childhood Blindness : Disease burden Group of diseases and conditions occurring in childhood or early adolescence, If left untreated, result in blindness or severe visual impairment that are likely to be untreatable later in life
Childhood blindness : Burden
Causes of childhood blindness around the world
Refractive Errors Very common eye disorder. Eye cannot clearly focus the images from the outside world. Result of refractive errors is blurred vision, Sometimes so severe that it causes visual impairment
low vision definition • (WHO) Low vision is visual acuity less than 6/18 and equal to or better than 3/60 in the better eye with best correction.
Refractive errors Burden In World. According to the most recent data available to WHO, there are an estimated 124 million people in the world with low vision . Severe refractive errors have been estimated to account for about 5 million blind people .
Refractive errors : Burden in India No nationwide reliable data on refractive errors. A survey indicated that 1 % of children in the age group (5 to 15 ) had vision < 6/18 in the better eye .(ref CME sereis 2009 NPCB)
Initiatives to Prevent blindness Global Level : Vision 2020 : Right to sight National Level : National Programme for Control of Blindness (NPCB)
Vision 2020: The Right to Sight
Vision 2020: The Right to Sight Global initiative launched by the World Health Organization and a Task Force of International Non-governmental Organizations in 1999
Six key strategic areas to produce an impact Advocacy for Eye Health. Policy & Program Development. Quality in Eye Care. Resource Mobilization & Sustainability. Research. Organizational Development.
Global conditions for immediate attention under Vision 2020
Five basic strategies to combat blindness
National Programme for Control of Blindness Launched in the year 1976 100 % Centrally Sponsored scheme. Goal to reduce the prevalence of blindness from 1.4% to 0.3 %.(2020)
