早产儿视网膜病1082例筛查报告及诊治分析

Objective To explore the early diagnosis and treatment of retinopathy of prematurity (ROP). Methods Totally premature infants with gestational ages of ＜ 34 weeks or a birth-weight ＜ 2 000 gwho were born in our hospital from July, 2004 to June, 2009, received ROP screen that was carried out by ophthalmologists with particular expertise in ROP using binocular indirect ophthalmoscope. The first screening began at 4 to 6 weeks postnatal age or 32 weeks of postconceptional age. The infants with threshold and prethreshold type Ⅰ ROP(severe) were treated with retinal laser photocoagulation. The infants with immature retinal blood vessels or stage 1 ～ 2 ROP or pre-threshold type Ⅱ ROP (mild) were followed up until retinal vessels are seen in zone Ⅲ or it gets to threshold and pre-threshold type Ⅰ ROP level. All clinical data were analyzed retrospectively. Results 1 082 of total 2 295 premature infants (47. 14% ) received ROP screening ia our department during the past5 years. 14. 23% ( 154/1 082) infants were diagnosed as ROP,the mild and severe ROP accounted for 7.94% (86/1 082) and 6. 28% (68/1 082) respectively. Six infants had to be rehospitalized as they developed into severe ROP during follow-up period. Of all the 68 infants with severe ROP,two infants with severe ROP were confirmed to be bilaterally blind because they had intermitted therapy for one year. Sixty-six infants ( 132 eyes) received various treatments. Sixty-three cases were treated with photocoagulation therapy alone. Of the remaining 3 infants with aggressive posterior ROP, two infants were injected intravitreously with antagonist of vascular endothelial growth factor (Avastin) and photocoagulation,One who was found retinal detachment after photocoagulation therapy alone and then treated with vitrectomy,was blind finally. The eyesight of total 65 infants were saved successfully, the success rate of treatment was 98.48% (65/66). During the surveillance period, none of the infants who had received photocoagulation died,but 10 infants died of the deterioration of the original disease before they were able to receive photocoagulation. Conclusion ROP screening is an effective measure to prevent the progression of ROP. Laser photocoagulation is a safe and effective method for the infants with severe ROP. Photocoagulation combined with Avastin can save the sight of the premature infants with aggressive posterior ROP.
