Light panretinal photocoagulation (LPRP) versus classic panretinal photocoagulation (CPRP) in proliferative diabetic retinopathy 总被引:1,自引:0,他引:1

PURPOSE: We misled to verify whether a panretinal photocoagulation (PRP) performed using low levels of ARGON laser energy (light PRP) has the same efficacy as a PRP performed in a conventional fashion using argon green wavelengths (classic PRP) in eyes with high-risk proliferative diabetic retinopathy (HRPDR). Furthermore, we misled to compare the session number performed and the side effects produced by the two techniques. METHODS: Sixty-five eyes with HRPDR of 50 consecutive patients were enrolled in a prospective randomized controlled trial. In eyes selected for light PRP, a very light biomicroscopic effect on the retina was obtained for each spot. In eyes assigned to classic PRP, each spot produced a white-yellow biomicroscopic effect. Mean follow-up was 22.4 months +/- 9.7 in the light PRP and 21.6 months +/- 9.3 in the classic PRP group (p = 0.727). RESULTS: The initial mean logMAR visual acuity (VA) in the light PRP group was 0.12 +/- 0.13 and in the classic PRP group 0.14 +/- 0.15 (p = 0.493). The final mean VA in the former was 0.18 +/- 0.25, and in the latter 0.27 +/- 0.30 (p = 0.231). Median power was 235mW (100-540mW) for light and 420mW (200-950mW) for classic PRP (p < 0.001). Regression of HRPDR at the end of the follow-up was obtained in 30/31 eyes (97%) treated with classic PRP and in 31/34 eyes (91%) treated with light PRP (p = 0.615). The total mean session number was 7.4 +/- 2.4 for light and 9.9 +/- 2.2 for the classic PRP group (p < 0.001). Complications were more frequent in the classic PRP group. CONCLUSIONS: The efficacy of Light PRP is similar to that of classic Light PRP in eyes with HRPDR. Light PRP is associated with fewer complications and allows the reduction of the number of treatment sessions. 相似文献

BackgroundThe prospective DIabetes and CATaract Study II (DICAT II) was performed to characterise the risks of cataract surgery to the retinae of patients with early diabetic macular oedema (E-DMO).MethodsDICAT II was a prospective, comparative, multicentre, observational study involving six Italian clinics. Patients were aged ≥55 years, had type 1 or 2 diabetes with spectral-domain optical coherence tomography evidence of ESASO classification Early DMO. Group 1 eyes (78 eyes, 78 patients) underwent phacoemulsification-based cataract surgery. Group 2 eyes (65 eyes, 65 patients) had E-DMO and either clear media or had undergone uncomplicated cataract surgery ≥1 year previously. Central subfield thickness (CST) and best-corrected visual acuity (BCVA) were assessed in both groups.ResultsThe negative impact of surgery on CST was evident after the first postoperative week; CST peaked during the first month, then rapidly decreased. CST worsening ≥10 µm was observed in 63/78 eyes (80.7%) and 29/65 eyes (44.6%) in Groups 1 and 2, respectively (p < 0.0001). CST worsening of ≥50 µm was observed in 51 eyes (65.4%) and 10 eyes (15.4%) in Groups 1 and 2, respectively (p < 0.0001). Mean CST worsening was lower in Group 2 than in Group 1 (38.6 ± 30.4 µm vs 85.5 ± 55.3 µm, p < 0.0001) with a lower BCVA loss (−2.6 ± 3.5 letters vs −8.2 ± 6.2 letters, p < 0.0001). Higher glycaemic levels and HBA1c levels were significantly associated with the risk of >50 μm CST worsening in eyes from both groups.ConclusionEarly DMO is associated with poorer outcomes after cataract surgery and requires close pre- and postoperative monitoring.Subject terms: Outcomes research, Retinal diseases, Lens diseases 相似文献
