| 概要 | Purpose:Recently, it is well known that early vitrectomy for proliferative diabetic retinopathy (PDR) is useful in order to increase the chance of restoring better visual outcome, and tended to maintain better visual acuity during follow-up than those assigned without surgery.
PDR in younger patients tends to progress quickly compared to elder patients. Thus we investigated the outcome after pars plana vitrectomy (PPV) for PDR in order to clarify the relationship between age and visual prognosis. Method:We retrospectively reviewed the clinical records of PDR patients who received PPV at Kansai Medical University Hirakata Hospital during the period of January 2006 to July 2009. Ninety-seven patients (129 eyes) were recruited. We divided all the cases into two groups by age, younger group (under 45 years old) and elder group (over 46 years old). We studied the best-corrected visual acuity (BCVA) of first visit, before surgery, and final visit, total number of operation, and operative complications for each groups. Results:Forty eyes of 25 cases were grouped in younger group and their mean age was 38.9 (range 30 to45). Eighty-nine eyes of 72 cases were grouped in elder group and their mean age was 59.8 (range 46 to 82). The mean postoperative follow-up periods were 15.5 months in juvenile group, and 17.4 months in elder group (statistically not significant). The post-operative visual acuity ware significantly better than pre-operative visual acuity in each group. (younger group: p=0.0005、elder group: p=0.0003) . The change of BCVA at final visit compared to that of before operation improved by 0.2 logMAR value was 19 eyes (51.4%) in younger group and 40 eyes (44.9%) in elder group. Visual outcome unchanged (within 0.2 logMAR value change) was 15 eyes (40.5%) in younger group, 24 eyes (27.0%) in elder group. Visual outcome worsened (more than 0.2 logMAR value increased) was 3 eyes (8.1%) in younger group and 25 eyes (28.1%) in elder group. |
