| Summary: |
Purpose: To evaluate the
results of cataract surgery in patients with RP because
retinitis pigmentosa is one of the disease entities that
belongs to tapeto-retinal degenerations. The occurrence
of RP appearance is 1: 4000 to 1: 3000.
Material and methods: Twenty patients with RP (7 women
and 13 men, 33 eyes), who underwent cataract surgery
were examined retrospectively. Average age in our group
was 46.6 years. Visual acuity, intraocular pressure,
slip lamp examination, fundus examination, cataract
morphology, visual field were taken before surgery and
on discharge, on the basis of medical documentation.
Control examination was taken, on average, eighty one
months after cataract surgery. Nine eyes were operated
by phacoemulsification, 24 eyes by means of
extracapsular cataract extraction. In the same way
control group of 18 patients who underwent cataract
surgery without RP (33 eyes) was examined.
Results: In RP group in 63.6% patients on discharge from
the hospital and in 60.6% patients during the control
examination, improvement of visual acuity was revealed.
Deterioration was noted in 18.2% of patients on
discharge from hospital and in 24.2% of patients during
the control examination. In the control group
improvement of visual acuity was revealed in 90.9% of
patients on discharge and in 97% patients during the
control examination, whereas deterioration of visual
acuity occurred in 6.1% patients on discharge and in 3%
patients during the check examination.
Conclusions: In patients with retinitis pigmentosa
cataract occurs earlier then in the control group.
Cataract surgery for relatively minor opacities is
beneficial in patients with RP, and causes improvement
of visual acuity in most of eyes undergoing surgery. |
