“…Zhou et al [23] demonstrated an increase in central retinal arteriolar equivalent and central retinal venular equivalent on the first day following strabismus surgery and reported that both double and single muscle surgeries may increase retinal blood flow in the early postoperative period but will return to normal later. Additionally, they detected retinal hemodynamic changes in the eyes undergoing only MR muscle surgery and argued that the main cause of these changes compared to inflammation was the number of transected ACAs, and at least two ACAs injuries were required to change retinal blood flow.…”

Background/Aim: Muscle trauma, vascular injury, and compensatory vasoconstriction during strabismus surgery may cause changes in the choroidal circulation in the early postoperative period. This study aims to evaluate the effect of extraocular muscle surgery on posterior ocular parameters, including central subfield thickness (CST), average retinal thickness (ART), choroidal thickness (CT), and macular volume (MV). Methods: This prospective cohort study included 26 eyes of 26 strabismic patients who underwent single medial or lateral rectus recession surgery using a fornix-based conjunctival incision. All participants underwent detailed ophthalmologic evaluation, including axial length (AL) and spherical equivalent (SE), uncorrected (UCVA), and best-corrected visual acuity (BCVA). Retinal and choroidal images were obtained using spectral-domain optical coherence tomography (OCT). All measurements were performed preoperatively and repeated 1 week and 1 month after surgery. Results: All patients received satisfactory results in terms of deviation. None of the patients showed changes in AL, SE, UCVA, and BCVA. No significant differences were noted in CST and MV values (P=0.472 and P=0.182, respectively). Although subfoveal CT and ART showed statistically significant decreases 1 week after surgery (P=0.012 and P=0.046, respectively), no significant differences in these values were observed 1 month after surgery (P>0.05). No significant differences exist in the measurements between the preoperative, postoperative first week, and first month in nasal and temporal CT (P>0.05). Conclusion: Extraocular muscle surgery performed with the fornix-based conjunctival incision is a safe procedure for posterior ocular parameters, including CST, ART, CT, and MV.

“…According to the formula developed by Knudtson(2003) et al, the retinal vessel measurements were summarized into central retinal artery equivalent (CRAE) and central retinal vein equivalent (CRVE), representing the diameters of arterioles and venules respectively. [15] The arteriole-tovenule ratio (AVR) was calculated as the ratio of CRAE to CRVE. Vessel tortuosity was assessed by visual grading of one fovea-centred and one disc-centred fundus image from each image.…”

Purpose To establish a prediction model for stroke side identification.Methods A total of 168 patients (89 left-sided stroke patients and 79 right-sided stroke patients) were recruited from the Shenzhen Traditional Chinese Medicine Hospital in the study. Retinal characteristics were analyzed using an automated retinal image analysis (ARIA) system. Multivariable logistic regression was used to identify and develop predictive models. Results Each unit increase in the right eye bifurcation coefficient of arterioles increased the risk of right-side stroke by 7.523 times (95% CI, 1.823-31.044). Additionally, an elevated bifurcation coefficient of venules in the right eye also increased the risk of stroke in the right side of the brain, with an odds ratio (OR) of 7.377 (95% CI, 1.771-30.724). A complex retinal composite score was also associated with a higher risk of right-side stroke (OR, 4.955; 95% CI, 3.061-8.022). Conclusion This study demonstrated that retinal image analysis can provide useful information for stroke side identification and the specific retinal characteristics may help in predicting stroke occurrence.
