ABSTRACT
Purpose@#To report the short-term clinical outcomes after intrascleral fixation of intraocular lenses (IOLs) using oblique intrascleral tunnels. @*Methods@#We retrospectively studied 17 patients (18 eyes) who underwent flanged intrascleral IOL fixation from October 2019 to October 2021. The patients were divided into those who underwent fixation using horizontal (group A) and oblique (group B) intrascleral tunnels. We compared the best-corrected visual acuities (BCVAs), cylindrical powers, refractive errors (the differences between the targeted spherical equivalents [SEs] and postoperative SEs) before and 3 months after surgery, and operating times. @*Results@#At 3 months vs. preoperatively, there were no significant differences in BCVA (-0.83 ± 0.43 vs. -0.48 ± 0.59), refractive error (-0.06 ± 0.97 diopter [D] vs. -0.05 ± 0.80 D), cylindrical power (-0.42 ± 3.81 D vs. -0.33 ± 1.20 D), or operating time (83.33 ± 28.05 minutes [min] vs. 66.33 ± 20.57 min) between groups A and B, respectively. @*Conclusions@#In terms of the short-term clinical outcomes after use of horizontal and oblique intrascleral tunnels, we found no significant differences in any parameters studied. However, use of an oblique intrascleral tunnel may shorten the operating time.
ABSTRACT
Purpose@#We report a case of neuroretinitis combined with external ophthalmoplegia in a patient who developed a cerebral venous sinus thrombosis after administration of a SARS-CoV-2 vaccine.Case summary: A 26-year-old woman who was on oral contraceptives was diagnosed with a cerebral venous sinus thrombosis 1 month after the first injection of a SARS-CoV-2 vaccine (BNT162b2, Pfizer-BioNTech). The levels of factors 8 and 9 were elevated on the blood test. The corrected visual acuities were 0.3 in both eyes. A complete limitation of abduction and esotropia were evident in the left eye. Both eyes exhibited optic disc swelling and hemorrhage and retinal nerve fiber layer swelling. Subretinal fluid was apparent in the right eye. Three weeks later, the optic disc swellings and hemorrhages had worsened and both eyes evidenced macular stars. After 10 months, the corrected visual acuities improved to 0.9 in both eyes. Ocular motor function and the esotropia also improved. However, the overall contraction of the visual field did not. @*Conclusions@#SARS-CoV-2 vaccination can trigger cerebral venous sinus thrombosis, neuroretinitis, and external ophthalmoplegia. In patients with risk factors for such thrombosis, the possibility of ophthalmic complications should be considered after administration of a SARS-CoV-2 vaccine.
ABSTRACT
Purpose@#To report a case of transient total occlusive attack of the ophthalmic artery with asymptomatic patent foramen ovale.Case summary: A 31‐year‐old female presented with worsening of intermittent visual loss in her right eye from the previous day. The visual acuity in the right eye was reduced to 0.04 at her first visual examination. In the doctor’s room, her visual acuity in the right eye improved to 1.0 at first; however, after several minutes, it decreased to no light perception. A relative afferent pupillary defect was observed. Following that, fluorescein angiography was performed, and visual acuity improved and worsened repeatedly; corresponding intermittent perfusion and occlusion of the ophthalmic artery were observed during the examination. Further evaluation was performed to determine the cause of intermittent occlusion of the ophthalmic artery; patent foramen ovale was diagnosed. Transient ophthalmic artery occlusion was presumed to have occurred owing to embolism by the patent foramen ovale. Aspirin was used as a prophylaxis. Since then, there have been no recurring symptoms of visual impairment. @*Conclusions@#Patients with ophthalmic diseases such as ophthalmic artery occlusion, retinal artery occlusion, and amaurosis fugax, especially young people, require a thorough assessment to identify potential causes of embolism.
