Aim and objective

AIM AND OBJECTIVE

Aim:

To evaluate the causes of blindness in children attending Schools for Blind in Pune and to record their improvement in functional vision with optical LVAs.

Objectives:

1. Causes of blindness among children in schools for blind in Pune.

2. Children in school for blind, who have Low Vision.

3. Improvement in visual acuity with optical LVAs.


Evaluation of the causes of blindness and improving the functional vision in children in schools for blind in pune

Prospective study

1. Poona School & Home For Blind Boys, Koregaon Park.

2. Poona School & Home For Blind Girls, Kothrud.

3. Patashibai Lunkar Blind School, Panjarpur, Bhosari.

4. NFBM Jagriti School For Blind Girls, Alandi Devachi, Khed.


Evaluation of the causes of blindness and improving the functional vision in children in schools for blind in pune

Inclusion Criteria:

All the candidates attending Schools for Blind between the age of 5-20 years of both the genders.

Exclusion Criteria:

1. Candidates absent from school.

2. Patients not willing to participate in study.

HEINE BETA 200 Retinoscope (US Pat.5.859.687).4.UNIQUE Distance Visual Acuity Test Chart (logMAR chart) calibrated for 4 meters & reduced snellen chart for near. 5.Telescopes of 2.25x,3.5x from Unique Educational Equipments 6.Magnifiers of (i) 5x illuminated stand magnifier (ii) 7.5x illuminated stand magnifier (iii) 2.5x stand magnifier (iv) 7.5x stand magnifier (v) 1.75x bar magnifier (vi) 1.75x fresnel magnifier (vii) 10D, 15D hand held magnifiers (viii) spot magnifiers of 24D, 32D, and 40x from Unique Educational Equipments were used.


Evaluation of the causes of blindness and improving the functional vision in children in schools for blind in pune

Procedure:

‘WHO/PBL Eye Examination Record For Children With Blindness And Low Vision’

Step 1: History taking of patient

Step 2: Visual Acuity Assessment

Step 3: Functional Vision Assessment:

Step 4: General Assessment

Step 5: Previous Eye Surgery

Step 6: Torch light, Slit lamp Examination and Ophthalmoscopy

Step 7: Refraction

Step 8: Low Vision Aid Assessment

Step 9: Action Needed

Step10: Full Diagnosis

Statistical Analysis: Microsoft Excel and SPSS software.

LVA for near:


Evaluation of the causes of blindness and improving the functional vision in children in schools for blind in pune

VII. Improvement with LVA:

  • Visual acuity for distance which was below 1in logMAR (unaided) in RE and LE has improved to 1.0(RE) and 0.9(LE) in logMAR with LVA for distance.


Evaluation of the causes of blindness and improving the functional vision in children in schools for blind in pune

Total LVA Prescribed:


Areas of improvement

Areas Of Improvement:

1.Data collected were from starting 5 years of age.

2.Children only of 4 schools were obtained.

3. Unavailability of telescopes from the manufacturers, made the examiner bound to use only two options (2.25x and 3.5x) for the distance LVA assessment.

4. Retinoscopy and ophthalmoscopy were done in undilated pupil.

5. Only optical LVA were used.


Conclusions

CONCLUSIONS

  • The major causes of blindness in children microphthalmos and anophthalmos.

  • Avoidable blindness like cataract accounted in 78 students. Lack of follow up and ampblyopia treatment.

  • Corneal blindness also accounted for 29% students.


Evaluation of the causes of blindness and improving the functional vision in children in schools for blind in pune

  • Out of the 460 students, 16.74% improved with LVA.

  • Students with Low vision were not given a chance prior to this study to improve their functional vision.

  • Regular print rather than Braille.

  • Visual Acuity achieved upto logMAR 1.0 and Near acuity upto N6.
