Evaluation of macular vessel density changes after strabismus surgery using optical coherence tomography angiography.

PURPOSE: To compare retinal vessel density before and after strabismus surgery using swept-source optical coherence tomography angiography (SS-OCTA). METHODS: In this longitudinal, single-arm pilot study, vascular density in the deep capillary plexus (DCP), superficial retinal capillary plexus (SCP) and choriocapillaris layer (CCL) in consecutive subjects undergoing strabismus surgery was assessed using SS-OCTA preoperatively (T0), on the first day postoperatively (POD1), and 30 days postoperatively (POD30). RESULTS: A total of 92 eyes of 56 patients (54% males) were included. Mean patient age was 41.1 ± 22.7. OCT vascular density of the DCP was 50.20 ± 5.57 at T0, 52.74 ± 4.77 at POD1, and 50.92 ± 4.58 at POD30. The differences were statistically significant for T0 versus POD1 (P < 0.05). Vascular density of the CCL was 50.72 ± 4.80 at T0, 53.59 ± 3.65 at POD1, and 51.39 ± 4.64 at POD30. The differences were statistically significant for T0 versus POD1 (P < 0.05). No significant differences were found in SCP (P > 0.05). CONCLUSIONS: Transitory hemodynamic changes can occur in the DCP and in the CCL following muscle recession procedures.

Publication Rate of Abstracts Presented at AAPOS Annual Meetings: From Conference Abstract to Full-Text Article.

PURPOSE: To review and analyze abstracts presented at American Association for Pediatric Ophthalmology and Strabismus (AAPOS) annual meetings, and to identify publication rates and potential predictive factors for better outcomes. METHODS: All abstracts accepted for presentation at AAPOS annual meetings from 2013 to 2017 were examined. A comprehensive literature search via PubMed and Scopus was conducted to identify whether the abstracts had been published as full text. A multivariate analysis was achieved to assess the factors related to successful publication, and a Kaplan-Meier analysis was performed to evaluate the publication time course of abstracts. RESULTS: Of 819 analyzed abstracts, 437 (53%) were published in peer-reviewed journals with a median impact factor of 2.7. The overall mean time to publication was 3 ± 2.2 years. The multivariate analysis revealed that abstracts were more likely to be published if they were accepted at an AAPOS annual meeting as an oral paper (P < .001), if they were prospective (P > .001) and multicenter (P = .013) studies, and if they had strabismus, retina, and vitreous disorders and diagnosis as main topics (P = .022). The Kaplan-Meier analyses revealed significant differences in the publication time distribution for multicenter versus single-center abstracts and paper versus poster and e-poster (P < .05). CONCLUSIONS: More than half of the abstracts accepted for presentation at the AAPOS annual meetings were published in peer-reviewed journals within 3 years from submission to the meeting. The factors associated with a higher publication rate were the prospective study design, multicentricity, and presentation at the meeting as an oral paper.
