In refractory diabetic macular edema, intravitreal triamcinolone effectively reduces foveal thickness and improves visual acuity in the short term, but with the extended follow-up, the number of recurrences and steroid-related complications were shown to increase. Nevertheless, it may be a therapeutic option in some patients that do not respond to previous laser photocoagulation.
Purpose:
To evaluate the possible hemodynamic changes following strabismus surgery via optical coherence tomography angiography.
Methods:
Thirty-two eyes of 16 patients who underwent strabismus surgery in one eye were included in the study. Fellow eyes were used as a control group. The vessel densities of the superficial and deep capillary plexus and superficial and deep foveal avascular zones were measured preoperatively and 3 months postoperatively.
Results:
The mean superficial and deep foveal avascular zones measurements were 0.84 ± 0.09 and 0.76 ± 1.13 mm
2
, respectively. The mean vessel density of the superficial capillary plexus was 1.23 ± 0.12 and 11.13 ± 1.04 mm
2
preoperatively in the 1- and 3-mm zones, respectively, whereas the mean vessel density of the deep capillary plexus was 1.13 ± 0.16 and 10.11 ± 1.28 mm
2
preoperatively. Postoperatively, the mean superficial and deep foveal avascular zones changed to 0.20 ± 0.13 and 0.23 ± 0.12 mm
2
, respectively. Postoperatively, the mean vessel density of the superficial capillary plexus changed to 1.47 ± 0.11 and 12.75 ± 1.10 mm
2
, and the mean vessel density of the deep capillary plexus changed to 1.56 ± 0.12 and 13.91 ± 1.35 mm
2
in 1- and 3-mm zones, respectively. There was a statistically significant increase in vessel density measurements of the superficial and deep capillary plexus, and a statistically significant decrease in measurements of the superficial and deep foveal avascular zone postoperatively (
P
< .05). In the fellow eyes, there was no statistically significant change in any of the measurements (
P
> .05).
Conclusions:
Following strabismus surgery, vessel density of the fovea may increase and the foveal avascular zone may decrease according to optical coherence tomography angiography measurements.

A case of postoperative large anterior staphyloma of the sclera was treated with a dehydrated cadaveric dura mater patch graft. Structural integrity of the globe and a good cosmetic result were obtained after the surgery. During the follow-up of 2 years, no recurrence of staphyloma developed.
In healthy individuals, different imaging modalities can be used to measure LID, but AS-OCT can be used in pediatric age-groups as a preferred imaging method because it is easy and noninvasive.
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.
