Objective
To compare the incidence of cystoid macular edema (CME) after vitrectomy and CME after phacovitrectomy in patients requiring epiretinal membrane (ERM) removal.
Design
A retrospective, comparative, interventional study.
Methods
Medical records of patients who had undergone vitrectomy or phacovitrectomy for ERM removal by a single surgeon were retrospectively reviewed. Phacovitrectomy was performed in all phakic eyes and vitrectomy was performed in all pseudophakic eyes. Increased macular thickness (IMT) was defined as an increase in macular thickness by more than 10% at the postoperative week 4 visit compared to the measurements at baseline.
Results
There were 214 and 53 eyes in the Phacovitrectomy group and the Vitrectomy group, respectively. IMT occurred in 15.4% of the Phacovitrectomy group, which was higher than the incidence of 3.8% in the Vitrectomy group (p=0.023).
Conclusions
IMT, that is suspected to be a type of CME, was not uncommon (15.4%) after phacovitrectomy in phakic eyes but was uncommon (4.8%) after vitrectomy alone in pseudophakic eyes. Irvine-Gass syndrome appears to be triggered by crystalline lens removal itself rather than intraocular surgery or surgical trauma alone.

Objective
To describe the risk and nature of retinopathy of prematurity (ROP) in micro-premature infants (≤26 weeks’ gestational age [GA]).
Methods
Retrospective analysis of prospectively collected data from infants born at 22–26 weeks’ GA over a 5-year period.
Results
A total of 502 infants were identified, of whom 414 survived to discharge (82.5%). The Vermont Oxford Network database documented clinical follow-up data and ROP outcomes for all 414 patients; complete ROP clinical records were available for 294 of the infants who survived (70.8%). Forty infants were born between 22 and 23 weeks’ GA (group A, 13.6%), and 254 were born between 24 and 26 weeks’ GA (group B, 86.4%). Survival for group A infants was worse than that of group B infants (66.2% vs 85.4%; p < 0.01). Survival of group A infants improved during the study period (R2 = 0.625). Overall, 59.9% of infants developed any ROP and 8.5% developed type 1 ROP. Group A infants were more likely to develop ROP (90.0% vs 48.6%; p < 0.01) and type 1 ROP (30.0% vs 5.1%; p < 0.01) than group B infants. Group A infants developed ROP at an earlier age (32 + 6 weeks vs 33 + 3 weeks; p = 0.02) and were more likely to have zone I disease on presentation (65.0% vs 20.5%; p < 0.01), but there was no difference in the corrected gestational age of peak severity of ROP (35 + 2 weeks vs 34 + 5 weeks; p = 0.36).
Conclusion
The most premature infants, born at 22–23 weeks’ GA, develop ROP at an earlier age, are more likely to present with posterior disease, and have a high risk of disease requiring treatment.
方法回顾性分析前瞻性收集的数据，这些数据来自 5 年内出生时胎龄在 22-26 周的婴儿。佛蒙特州牛津网络数据库记录了所有 414 名患者的临床随访数据和 ROP 后果；294 名存活婴儿（70.8%）有完整的 ROP 临床记录。40 名婴儿出生时的胎龄为 22-23 周（A 组，13.6%），254 名婴儿出生时的胎龄为 24-26 周（B 组，86.4%）。A 组婴儿的存活率低于 B 组婴儿（66.2% vs 85.4%；P < 0.01）。在研究期间，A 组婴儿的存活率有所提高（R2 = 0.625）。总体而言，59.9%的婴儿患上了任何一种视网膜病变，8.5%患上了1型视网膜病变。与 B 组婴儿相比，A 组婴儿更容易患上 ROP（90.0% vs 48.6%；p <；0.01）和 1 型 ROP（30.0% vs 5.1%；p <；0.01）。A 组婴儿发生 ROP 的年龄更早（32 + 6 周 vs 33 + 3 周；p = 0.02），更有可能在发病时患有 I 区疾病（65.0% vs 20.5%；p < 0.01），但 ROP 严重程度达到峰值的校正胎龄没有差异（35 + 2 周 vs 34 + 5 周；p = 0.36）。结论22-23周出生的早产儿罹患视网膜病变的年龄较早，更有可能出现后发疾病，且需要治疗的风险较高。
