Due to differences in aetiologies, clinical characteristics, required surgical procedure after initial repair, surgical and functional outcomes, paediatric RD with extreme myopia should be addressed differently from paediatric RD with high myopia.
Although all E. faecalis isolates were susceptible to vancomycin, endophthalmitis caused by E. faecalis was usually associated with poor visual prognosis.

Abstract.
Purpose: This study aimed to examine the correlation between glycosylated haemoglobin (HbA1c) level and macular volume in diabetes patients without diabetic macular oedema (DMO).
Methods: We carried out an observational, cross‐sectional study. Patients who had diabetes mellitus (DM) of ≥ 10 years duration without DMO were included. Only one eye of each patient was selected for analysis. Eyes with proliferative diabetic retinopathy were excluded. Central subfield thickness (CST), central subfield volume (CSV) and total macular volume (TMV) were measured by optical coherence tomography (OCT). Chronic HbA1c level was defined as the mean HbA1c value in the year prior to enrolment.
Results: We included 97 eyes from 97 patients (47 women, 50 men; mean age 62.2 years). They included eight type 1 and 89 type 2 DM patients. The mean duration of DM was 15.5 years. Forty‐two (43%) eyes had no diabetic retinopathy and 55 (57%) eyes had non‐proliferative diabetic retinopathy. In statistical analysis, CST (mean 188.80 ± 27.64 μm; r = 0.220, p = 0.030), CSV (mean 0.149 ± 0.021 mm3; r = 0.213, p = 0.036) and TMV (mean 6.497 ± 0.715 mm3; r = 0.299, p = 0.003) positively correlated with chronic HbA1c level (7.95 ± 1.29%). The linear regression model showed that chronic HbA1c level (standardized coefficient 0.253; p = 0.013) and age (standardized coefficient − 0.206; p = 0.040) were factors significantly related to TMV.
Conclusions: Chronic HbA1c level positively correlates with macular thickness and volume in patients with DM of ≥ 10 years duration without DMO. Our results suggest that subclinical macular volume and thickness changes may occur before DMO becomes clinically evident. Early tight glycaemic control prior to the onset of DMO may play an important role in preventing the deterioration of macular function by altering macular haemodynamics.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
