Objective To determine the long-term outcome of treatment for threshold retinopathy of prematurity (ROP) in one UK unit. Methods A total of 35 infants diagnosed with threshold ROP were treated by a single ophthalmologist (DGC) between 1987 and 1998. The parents of the 29 surviving patients were contacted; 21 brought their child for special review of acuity, motility, refraction and fundoscopy (Group 1). Of the eight patients who were unable to attend, six patients (Group 2) had sufficient follow-up detail in their records to be included in the study. Results A total of 40 eyes in the 21 patients in Group 1 had been treated; 10 had received cryotherapy (eight bilateral) and 11 had bilateral laser. Mean follow-up was 5 years (range 2-12 years). A total of 23 treated eyes (in 16 patients) had an acuity of 6/12+ (57.5% of treated eyes). Four eyes of three patients had no light perception. Seven eyes in four patients had myopia of more than 3 D. Eight patients had a manifest squint: six esotropia, two exotropia. The retinal status of 36 eyes (90%) showed a favourable outcome. The four blind eyes had stage 5 disease. In Group 2, four eyes of two patients (33%) had 6/12+ acuity recorded; five eyes in three patients had stage 5 disease and no perception of light. In total, a favourable structural outcome was achieved in 81.4% and favourable functional outcome observed in 74.6%. Conclusion These results show that the favourable outcomes reported in the CRYO-ROP trial can be achieved in routine practice and maintained after long follow-up.
