One of the most exciting recent development in the field of ophthalmology is pleoptics. Reports on the studies of the pathophysiology and therapeutics of amblypia has been recently increasing in the world's literature. Unfortunately no report on this field is seen here.
The author intends to investigate the problems of amblyopia, its incidence and nature in Taiwan.
Survey on the children in Tung Meng Primary School and O. P. D. patients in the National Taiwan University Hospital is reported in the first section.
Results of detailed examination and treatment on the amblyopic patients are reported in the second section.
Classification by Bangerter was used.
1) The incidence of amblyopia in the above mentioned two groups are listed below. No organic amblyopia was included.
(The form abridges)
No difference was found between the incidence of male and female both in Tung Meng Primary School children and in O.P.D. patients.
There was also no difference found between the right and left eye in both groups.
Incidence of amblyopia in esotropia is much higher (59.18%) than that in exotropia (32.00%).
2) Eccentric fixation was found in 54.84% in pure amblyopia patients.
Occlusion therapy consisting of total occlusion was given to 8 cases, and 7 cases showed
improvement including 2 cases attained the good vision of 0.8 and 1.0 respectively.
Failure of one case was attributed to the too limited occlusion.
After image teatment of Cüppers was tried to 10 cases. Treatment consisted of 3 sessions in 30~40 minutes daily combined with coordinator training. Treatment was given at O.P.D. base, and no patient was admitted to our ward.
Among 10 cases 7 cases showed improvement including 3 cases which reached the vision level of 0.5 or more. One case to be especially noted is a 8 yr. old boy who had a marked improvement in vision (0.0l→0.4) and fixation (wavering→parafovea1 fixation) after 4 months treatment. In three cases failure was attibuted to few treatment of only 2 weeks or less.
Beause good result was obtained by treating 4 patints who had amblyopia since the age of one, the author argued about the applicability of the theory of amblyopia of arrest in these cases and inclined to agree on the cortical 5nbiitional theory of Burian. Importance of continued and prolonged therapy of at least 4 weeks was stressed.
The need for amblyopia sohool and pleoptic technician is cited.
