| Summary: |
Purpose: To
evaluate whether the periodical sensory deprivation due
to senile cataract and leading to strabismus, can result
in the loss of binocularity.
Material and methods: We examined 26 patients
with dense cataract in one or both eyes and with
strabismus that appeared after development of cataract
in the absence of any other ophthalmological defect. All
the patients had cataract extracted in one or both eyes
by the method of phacoemulsification with implantation
of PC IOL. Examination included: measurement of
deviation of the eye for distance before and after
surgery, visual acuity before and after treatment,
stereopsis on Titmus test for distance.
Results: All patients had exodeviation of -10 to
-40 degrees before surgery. Visual acuity before
treatment was low: maximum was 0.1. 81% of patients had
VA on the level of hand movement or worse. Six months
after treatment 19 patients were orthotopic, and in 7
patients the deviating eye changed (these patients had
cataract in both eyes). 2 of these patients had cataract
surgery and regained orthotopic position. Among 21
orthotopic patients after surgery, stereopsis was
present in 18 (86%).
Conclusions: Sensory deprivation due to dense
cataract can cause exodeviation. In most cases it does
not lead to loss of binocularity. |
