Endophthalmitis after 25-gauge and 20-gauge pars plana vitrectomy: incidence and outcomes
To compare the rates of endophthalmitis after 20-gauge versus 25-gauge pars plana vitrectomy (PPV) and to investigate clinical features of, and visual acuity outcomes, for patients with endophthalmitis after PPV.
A computerized database search was performed at each author's institution to identify all patients who underwent PPV by any of the authors between January 1, 2005, and December 31, 2006, and were subsequently treated for endophthalmitis. In addition, all patients who underwent PPV and were subsequently treated for endophthalmitis at Pennsylvania State College of Medicine (Hershey, PA) and Bascom Palmer Eye Institute (Miami, FL) during the study period were included. The medical records of these patients were reviewed to confirm that the endophthalmitis was associated with PPV and to collect clinical data to meet the study objectives.
The incidence of endophthalmitis during the study period was 2 cases per 6,375 patients (or 1 case per 3,188 patients; 0.03%) for 20-gauge PPV compared with 11 cases per 1,307 patients (or 1 case per 119 patients; 0.84%) for 25-gauge PPV (P /=20/400, and four had visual acuity of >/=20/63. Cultures were negative in three cases; no culture specimens were obtained in one case. Six of the seven isolates were coagulase-negative staphylococci, and one was enterococcus. Five of six isolates tested for sensitivity to vancomycin were sensitive, and both isolates tested for sensitivity to ceftazidime were sensitive.
The rate of endophthalmitis after 25-gauge PPV was significantly higher than that after 20-gauge PPV. Endophthalmitis after 25-gauge PPV occurred within 15 days of PPV, was usually due to coagulase-negative staphylococci sensitive to vancomycin, and was associated with variable visual outcomes

Referable Macular Hemorrhage-A Clinically Meaningful Screening Target in Newborn Infants. Position Statement of the Association of Pediatric Retina Surgeons
Universal newborn eye screening facilitates early diagnosis of ocular abnormalities and mitigates vision loss. "Referral warranted" eye disease is present at birth in about 5.5% of term infants, with "macular hemorrhage impinging on the fovea" representing about 50% of referral warranted disease. The Association of Pediatric Retina Surgeons held a symposium on February 9, 2021 that culminated in a position statement on "referable macular hemorrhage" (RMH) in newborn infants. RMH is meaningful in that in can cause amblyopia through deprivation, can be readily captured with wide-angle photography in a safe and efficient manner, and may lead to early intervention with mitigation of vision loss
Safety and efficacy of simultaneous bilateral 25-gauge lens-sparing vitrectomy for vascularly active stage 4 retinopathy of prematurity
Late-Onset Retinal Findings and Complications in Untreated Retinopathy of Prematurity
PURPOSE: To investigate late retinal findings and complications of eyes with a history of retinopathy of prematurity (ROP) that did not meet treatment criteria and did not receive treatment during infancy.
DESIGN: Retrospective, nonconsecutive, noncomparative, multicenter case series.
PARTICIPANTS: Three hundred sixty-three eyes of 186 patients.
METHODS: Data were requested from multiple providers on premature patients with a history of ROP and no treatment during infancy who demonstrated late retinal findings or complications and included age, gender, gestational age and weight, zone and stage at infancy, visual acuity, current retina vascularization status, vitreous character, presence of peripheral retinal findings such as lattice retinal tears and detachments (RDs), retinoschisis, and fluorescein findings.
MAIN OUTCOME MEASURES: Rate of RDs and factors conferring a higher risk of RDs.
RESULTS: The average age was 34.5 years (range, 7-76 years), average gestational age was 26.6 weeks (range, 23-34 weeks), and average birth weight was 875 g (range, 425-1590 g). Findings included lattice in 196 eyes (54.0%), atrophic holes in 126 eyes (34.7%), retinal tears in 111 eyes (30.6%), RDs in 140 eyes (38.6 %), tractional retinoschisis in 44 eyes (11.9%), and visible vitreous condensation ridge-like interface in 112 eyes (30.5%). Fluorescein angiography (FA) was performed in 113 eyes, of which 59 eyes (52.2%) showed leakage and 16 eyes (14.2%) showed neovascularization. Incomplete vascularization posterior to zone 3 was common (71.6% of eyes). Retinal detachments were more likely in patients with a gestational age of 29 weeks or less (P \u3c 0.05) and in eyes with furthest vascularization to posterior zone 2 eyes compared with zone 3 eyes (P = 0.009).
CONCLUSIONS: Eyes with ROP not meeting the treatment threshold during infancy showed various late retinal findings and complications, of which RDs were the most concerning. Complications were seen in all age groups, including patients born after the Early Treatment for Retinopathy of Prematurity Study. Contributing factors to RDs included atrophic holes within peripheral avascular retina, visible vitreous condensation ridge-like interface with residual traction, and premature vitreous syneresis. We recommend regular examinations and consideration of ultra-widefield FA examinations. Prospective studies are needed to explore the frequency of complications and benefit of prophylactic treatment and if eyes treated with anti-vascular endothelial growth factor therapy are at risk of similar findings and complications
