【Abstract】 ObjectiveTo evaluate the effect of the treatment of diode laser for retinopathy of prematuriy (ROP). MethodsSix-eight premature infants, with the gestation <32 weeks and birth weight < 1 500 g, were examined 6-7 weeks after birth. The infants suffering from threshold ROP were treated by diode laser through a binocular indirect ophthalmoscope within 48 hours after the confirmation of diagnosis, and with the follow-up of 4～6 moths. Retinal detachment was found in 1 eye 1 month after laser treatment, and scleral encircling operation was performed on the eye which was followed up for 3 months after the operation. Cycloplegic refractive examination was performed on the eyes with threshold ROP 4 months postnatally to determine the presence of refractive errors. ResultsSix infants (1) eyes were diagnosed as with threshold ROP.The average age of the occurrence of threshold ROP were (10±2.89) (ranging from 6 to 14 weeks) weeks postnatally. The successful rate of diode laser treatment was 91.67%. Retina was flat in one eye treated by scleral encircling operation. Refractive errors of the eye treated by scleral encircling operation was -14.5 D, and the median spherical equivalent errors in other 11 eyes was (-2.89±-1.86) D. ConclusionThe treatment of diode laser is effective for threshhold ROP.更多还原
