Purpose To determine if increasing drusen height correlates with predictive optical coherence tomography (OCT) biomarkers of atrophy. Methods Retrospective cross-sectional study that enrolled patients with drusen associated with intermediate AMD. Macular drusen were classified as small, intermediate, large, or very large based on OCT quartile measurement of height. Drusen diameter was also tabulated. The presence and localization of the OCT biomarkers of atrophy were assessed: disruption of the external limiting membrane and ellipsoid zone, intraretinal hyper-reflective foci, RPE disruption, choroidal hypertransmission, and presence of hyporeflective cores. Predictive OCT biomarkers of atrophy were correlated with drusen height. Results A total of 155 eyes from 104 patients met the inclusion and exclusion criteria. The mean age was 75.7 ± 8.7 years, and patients were predominantly female (74.0%). The mean visual acuity was logMAR 0.2 ± 0.2 (Snellen equivalent 20/32). The average drusen height was 134.6 ± 107.5 µm and the greatest horizontal diameter was 970.7 ± 867.4 µm. Disruption of the external limiting membrane and ellipsoid zone, RPE thickening or thinning, intraretinal hyper-reflective foci, choroidal hypertransmission, and presence of hyporeflective cores ( P < 0.05) were more common in eyes with large drusen and very large drusen versus small or intermediate drusen. All biomarkers were positively correlated with drusen height. OCT biomarkers of atrophy were predominantly located at the apex of the drusen. Conclusions Predictive OCT biomarkers of atrophy, specifically signs of RPE breakdown and disruption, occur more commonly in large or very large drusen, especially in drusen with greater height and separation of the RPE from the underlying choroid.

Purpose: To describe the mechanisms and outcomes of open globe injuries (OGIs) in patients 70 years or older. Methods: A retrospective chart review of patients from two large academic centers in Israel who were underwent surgery for OGI. Data was collected from surgical and clinic charts. Anatomical and functional results were recorded as well any additional surgeries and complications. Results: Thirty-two eyes of 32 patients were included. The mechanism of OGI consisted of blunt trauma with ocular rupture secondary to falls. All eyes underwent immediate primary closure of the corneal and scleral lacerations. Additional surgeries were performed in 34.3% of cases. In 31.2% of cases additional surgery was not required, and in 21.9% of cases the damage was so devastating that additional procedures were not recommended. Four patients (12.5%) chose not to undergo additional surgery. Mean visual acuity at presentation was 2.24 ± 0.72 logMAR and it improved to 1.92 ± 0.89 logMAR at final follow-up ( p = 0.002). VA at presentation was significantly correlated to final VA ( p < 0.001). Conclusions: OGI in the elderly represents a unique group. It is mostly related to falls, with a female predominance and a poor visual prognosis. In this patient population, general health concerns and increased risks of anesthesia require special attention. Care should be taken to educate elderly patients and their caretakers on how to avoid falls.

Purpose To report the epidemiology of the surgical indications of pars plana vitrectomy in patients aged 75 years or older. Patients and Methods The medical records of patients who underwent vitrectomy surgery in a single center between 2008 and 2018 were evaluated retrospectively for demographics, medical background, and surgical indications. Data on patients aged 75–85 were compared to those of patients older than 85 years and those recorded between 2008–2013 and 2014–2018. Results A total of 592 patients were included, of whom 55% were males. The mean±standard deviation age of the cohort at presentation was 80.4±4.60 years, and the mean visual acuity was 1.3±0.93 logMAR. The main indications for surgery were retinal detachment (n=117, 19.7%), epiretinal-membrane/vitreomacular traction (n=140, 23.6%), dropped intraocular lens/retained lens (n=89, 15%), macular hole (n=64, 11%), submacular hemorrhage (n=40, 6.7%), diagnostic vitrectomy (n=37, 6.2%), non-diabetic vitreous hemorrhage (n=30, 5.1%), and diabetic vitreous hemorrhage and other diabetic complications (n=33, 5.6%). Patients aged 85 years and older had higher rates of urgent surgeries (65%), such as for submacular hemorrhage and trauma ( p =0.0000039 and p =0.001, respectively), and lower rates of non-urgent surgeries, such as for epiretinal membrane and macular hole ( p =0.000032 and p =0.02, respectively), compared to patients aged 75–84 years. Additionally, the surgical rate for submacular hemorrhage decreased during 2008–2014 compared to 2014–2018 ( p =0.000014). Conclusion Understanding the unique distribution of indications for vitrectomy among elderly patients is essential for appropriate management and treatment. Urgent cases represent 65% of the surgeries performed in the older population.
