 WHY ? School going children—25% WHAT IS THE NEED ?  School going children represent a needy and Big target group

 School eye health programme started in1984  AIM  PREVENTION OF BLINDNESS IN SCHOOL GOINING CHILDREN.  BY

 COMPONENTS  examination by teacher at school  Vision not good V good  examination by PMOA  at PHC  Simple complicated V good  Spectacles examination by  ophthalmic surgeon

Magnitude Of The Problem Children are blind per 10, million Children are blind –global figure INDIA Children in school going age > 25% of the population million school going children are there. -Every year 50,000 children go blind in

Main Causes - Malnutrition - Illiteracy - Accessibility to eye facility is difficult in 70-80% children SCHOOL EYE HEALTH

Why Teachers are involved in school eye screening programme ? SCHOOL EYE HEALTH

 1.they are the large group  2.reading and writing are their felt needs.  3.the teachers see their pupils daily.  4. the teachers can insist on the children to use them spectacles regularly.

School Eye Screening Programme Aim Objective Strategy Need Between 2,000-10,000 children per million population have refractive errors > -1D sphere in both eyes. Approximately 20,000 children/million population have refractive errors in both eyes and hypermetropia of greater then +3 D Sphere.

1.Hypermetropia 2.Myopia 3.Astigmatism II Squint & Ambolypia III Infectious Diseases IV Trauma V Vit. A Deficiency I. REFRACTIVE ERRORS

Characteristics Of The Children With Visual Defects. - Children usually don’t complain of defective vision. - They may not even beware of their visual problem. - They adjust to the poor eye sight by sitting near the black board,holding the books closer to their eyes,squeezing the eyes and even avoiding work requiring visual concentration. - Try to copy from the next child sitting beside. - Slow student. - Hesitate to participate in curricular & extra curricular activities.

 The condition in which incident parallel rays of light do not come tofocus up on the retina.  It may be due to  1.abnormal length of the globe  2.abnormal curvature of the cornea or lens  3.abnormal position of the lens.

 Parallel rays of light come to focus on the retina

 Parallel rays of light come tofocus anterior to the retina

 Sympom is distant vision is blured.  Obsers tv very closely

 Treatment  1.spectales.  2.laser assisted insitu  Keratomileusis.(LASIK)

 Parallel rays come to focus posterior to the retina.

 Symptoms are noticed after close work.  The eye ache and burnningsensation.they may feel dry, so, that blinking movements are more frequent. prolonged near work produces head ache.  Recurrent attacks of styes, blepharitis, chalazion present.

 1.correcting lenses prescribed.

 Parallel rays of light come to focus at more than one point.

 Causes lowering of visual acuity.  Head ache.

 1.spectales.  2.c l.

 Crystalline lens has been removed

 Cong.cataract causes squint
