Retinopathy of Prematurity Screening

Screening for premature retinopathy is a necessary screening program for preterm infants, with a prevalence of up to 20% in preterm infants. The early boundary of the lesion between the vascular and avascular regions of the retina is a clinically characteristic sign of premature retinopathy. Proliferative lesions at the boundary, abnormal retinal vessels, and varying degrees of traction retinal detachment, and advanced changes should be considered for the diagnosis of recurrent retinopathy. In the late stage of the lesion, the anterior chamber becomes shallow or disappears, which may be secondary to glaucoma and corneal degeneration. Basic Information Specialist classification: Ophthalmology classification: pathological examination Applicable gender: whether men and women apply fasting: not fasting Tips: Before the examination, children need to fast for two hours. Normal value The baby's vision is normal and the visual network blood vessels are well developed. Clinical significance Abnormal results premature infants have no development of retinal neovascularization and fibrosis in the retinal vessels. Most of them are bilateral eyes. The light can be self-healing. In severe cases, blindness may occur due to retinal detachment. The early boundary of the lesion between the vascular and avascular regions of the retina is a clinically characteristic sign of premature retinopathy. Proliferative lesions at the boundary, abnormal retinal vessels, and varying degrees of traction retinal detachment, and advanced changes should be considered for the diagnosis of recurrent retinopathy. In the late stage of the lesion, the anterior chamber becomes shallow or disappears, which may be secondary to glaucoma and corneal degeneration. Premature and low birth weight children need to be examined. Precautions Taboo before the test: the child needs to fast for two hours. Half an hour before the examination, the doctor first used the dilating drug to enlarge the pupil of the child. Requirements for examination: The doctor first performed topical anesthesia for the child, then placed the opener, and examined the retina with binocular indirect ophthalmoscope and retinal camera in the dark room to record the retinopathy. Half an hour after the examination, the child can eat. Inspection process From the 4th to 6th week after birth, the compound tropamide or Midea is sputum, the surface anesthetic is dripped, and the pediatric sputum is opened. The binocular indirect stereogram is used in the dark room, and the fundus examination is performed in combination with the scleral compressor. . Not suitable for the crowd Inappropriate crowd: None.
