I. Purpose: To evaluate the importance of Low Vision Aids in Toxic Optic
Neuropathy treated with medication. II. Method: 36 years old patient with
toxic optic neuropathy. Fundus assessment revealed inflamed oedematous
greeyinsh white optic discs. The patient treated with Vit. B12 and 40 mg
Methylprednisolone tab. and Vexol eye drops. After 3 weeks there was full
healing for the optic disc. The vision also was stable so low vision aids test
start. III.
Results: The initial visual acuity was 20/400 right eye and 20/200 left ete at
distance. After the full course of medical treatment the vision improve up to
20/200 right eye and 20/100 left eye. Low Vision Aids improve the vision up to
20/40 right eye and 20/28 left eye and for reading the patient can use Clipon
(2.5x). The patient can read up to 20/40 = 0.8 =53 and he was so happy. In
Conclusion:
Low vision aids, still play an important role to improve the quality of far and
near vision in toxic optic neuropathy treated with medication.

To evaluate the importance of Low Vision Aids in Exudative Age
Related Macular Degeneration treated with Photodynamic therapy

2. Member of Contact Lens Society Of America
Purpose: To evaluate the importance of Low Vision Aids in Exudative Age
Related Macular Degeneration treated with Photodynamic therapy Method:
80 years old patient with exudative age related macular degeneration with
subfoveal choroidal neovascular membrane in left eye proved by intravenous
fluorescein angiography. 1st session of photodynamic therapy followed 3
weeks later by extra capsular cataract extraction and IOL implantation. Follow
up was achieved for 6 months by visual acuity and intravenous fluorescein
angiography with no recurrence of the membrane so Low Vision Aids test start
Results: The initial visual acuity was CF ½ m right eye and CF 1 m left eye.
After photodynamic therapy and cataract surgery the vision improve up to 0.05
20/400 left eye Low vision aids improve the vision up to 0.2 + 20/100, and for
reading, the patient can use C.C.T.V. camera, the patient can see up to J2 and
he was so happy
Conclusion: Low vision aids play an important role to ameliorate the quality of
far and near vision in exudative Age Related Macular Degeneration treated
with Photodynamic therapy

2. Jilin University
Purpose: To correct human color sense anomalies with new custom fitted filters
based on quantitative measurement of color spectral defects using a new
computor assisted diagnostic devise. Method: Using Ishihara plates, color
senses among 205,266 male military candidates were tested. 10,266 men
were identified as color blind. Those identified as color blind were further
tested with a new computerized devise and their deficiencies were classified
in 4 groups and 8 grades. Custom fitted filters were produced to balance the
spectral curves by attenuating areas of strong sensitivities.
Results: 99.9% of the color blind individuals were able to read all Ishihara
plates correctly with spectrum corrected filters.
Conclusion: Human color blindness was corrected by use of customized filters
fitted to balance the spectral defects as identified by new computerized analyses
of individual spectral defects. Target Audience:general ophthalmologists,
Educational Level:beginning, intermediate and advanced.

1. Islamic Azad University, Shahinfar Medical Faculty
Purpose:As presbyopia is prevalent in Iran, we decided to perform this study
for better understanding about different aspects of this disease in our region.
Methods: This descriptive cross sectional study was performed on 300 patients
that referred to Aria, Farabi and 22Bahman hospitals during one year. We
diagnosed the presbyopia by physical examination and looking for refractive
error or accommodation problems in individuals.
Results:Mean age was 51±8.68 and 50% were under 50 years old. There was
no significant difference between male and female but the onset of presbyopia
was 39 in females and 41 in males. The job of patients was analyzed in
this study , by which it was shown that among men, 41% had menial jobs
and 23.7% were employed in the office. 56% had a systemic disease history.
MDD, HTN and Migraine were the most common systemic diseases among
our patients. 56% of the patients had the history of medical drugs usage in the
past years. NSAIDS, Antidepressants, Narcotics and Anticolinergics was used
in 31.3%, 30%, 25.3% and 13.3% of all patients.
Conclusion: In our study, Some kind of drugs had effect on vision decrease but
the job had no effect on the onset of presbyopia.

A RARE CASE OF OPTIC NERVE HEAD DRUSEN
Jain Lokesh (1)
1. Jain Eye Hospital
Objective: To present a rare case of Optic nerve head drusen.
Methods: A 27year old male patient presented to us with difficulty in peripheral
vision. Appropriate ocular workup including visual fields, B-scan
ultrasonography, Fundus fluorescein angiography,Fundus photographs and
Heidelberg Tomograph imaging and systemic examination was also done.
Results:Patient was myopic.Fundus examination showed waxy pearl like
lesions on the disc,Visual field showed altitudinal defect in the right eye and
sectoral field loss in left eye .Red free photograph showed autofluorescence.
B-scan ultrasonograghy showed high reflective echo in optic nerve head
shadow. Hieldelberg Retinotomogram showed Small almost non existent cup
in both the eye. Diagnosis of bilateral optic nerve head drusen was made.
Conclusion: There is no existing treatment for optic nerve head drusen.Proper
follow up and patient education is the best-available modality of care.
