Visual acuity of majority of amblyopi, patients can be improved to considerablf extent by the use of contact lenses. Beside: contact lens correction combined witt pleoptics and orthoptics training may leac to improved binocular vision.
| Materials and methods|| |
The present series consits of 67 hypermetropic and 32 astigmatic eyes of 50 patients of amblyopia.
| Observations and discussion|| |
Out of these 50 cases, 36 patients (72%) were males and 14 patients (28%) were females. Maximum patients treated, ranged from 17 years to 22 years age group.
Maximum number of patients included in the study were below the age of 40 years. There appears a proportionate increase in incidence of the disease with increase in age, irrespective of the sex. This may be attributed to better detection of amblyopia in older patients. This upward trend was found only upto the age of 40 years. Thereafter, the incidence seems to decline. This could be apparent.
Improvement in distant vision with contact lenses was noted in 82.08% of cases. Improvement of one line was observed in 44.77% of two lines in 25.37°/'0, there lines in 8.94% and four and five lines each in 1.49% of cases. Contact lenses did not improve vision in 17.92% of cases.
Maximum improvement with contact lenses were observed in 2 patients from the group 13 patients having 6/36 vision i.e., upto four and five lines each. Maximum improvement was observed in groups having 6/24 and 6/36 vision i.e., of 100% and 92.3%, respectively. In groups having visual acuity less than 6/60, 6/60 and 6/9 vis on, improvement was observed in 87.50%, 87.50% and 85.70% respectively. In rest of the groups, improvement in visual acuity with contact lenses was found in 70% of cases.
Therefore, the chief conclusion of any ophthalmological significance, in the light of improvements marked in 55 eyes (82.08%) would be that at least 8 out of 10 eyes would find improvement in their vision by the use of contact lenses.
Improvement in near vision was recorded in 50 eyes (74.62%) out if total 67 eyes. No improvement was observed in 17 eyes (25.38%).
Thus it is clear that improvement in all the groups was of one line i.e., in 38.00% of cases. Two line improvement was observed in 16.41% of cases, three line in 13.43%, four line in 2.98% and five and six line improvement in 1.49% of cases each.
On the basis of these findings, it may be concluded that improvement in near vision with contact lenses are bound to occur to some extent in most of the cases.
With particular reference to the role of contact lcnscs in astigmatism, we found that out of 3 2 eyes, improvement of vision took place in 25 i.e., 78,12% of eyes. In all but two cases the improvement was by one line.
The fact that contact lenses may improve vision in patients labelled as amblyopia has to be kept in mind while selecting possible recruitees at the medical board examination.
