ABSTRACT

Purpose@#We report a case of sympathetic ophthalmia in which the inciting eye was treated with a tectonic keratoplasty using acellular preserved human cornea.Case summary: A 68-year-old man whose left eye was injured by a nail visited our institute complaining of a recent decrease in bilateral vision. The best corrected visual acuity was 0.32 for the right eye and 0.16 for the left. On slit-lamp examination, a superior peripheral corneal perforation with no wound leakage due to iris plugging was seen in the left eye (i.e., the inciting eye). The right eye (i.e., the sympathizing eye) had mutton-fat keratic precipitates and copious fibrinoid strands in the anterior chamber. Bilateral exudative retinal detachment with choroidal folds was prominent in both eyes. The next day, the necrotic iris lump was removed from the inciting eye and adhesiolysis of the iris and tectonic keratoplasty using acellular preserved human cornea were performed. Systemic steroid was started immediately postoperatively. The exudative retinal detachment improved in both eyes and cataract surgery was undertaken for the inciting eye 4 months later. Twenty-one months after the initial visit, the uncorrected visual acuity was 1.0 in the inciting eye, and both eyes had a sunset glow fundus appearance, without optic atrophy or recurrent chorioretinitis. @*Conclusions@#Tectonic keratoplasty using acellular preserved human cornea with anti-inflammatory treatment may be a favorable therapeutic option for the inciting eye with peripheral corneal perforation in sympathetic ophthalmia.

ABSTRACT

Purpose@#To evaluate the effectiveness and safety of treating choroidal melanoma and cancer that has metastasized to the choroid with gamma knife radiosurgery (GKR). @*Methods@#We performed a retrospective chart review that included 10 eyes of eight patients with a diagnosis of choroidal tumors who underwent GKR between January 2016 and February 2019 and who had at least one month follow-up visit. @*Results@#The mean patient age was 57.9 ± 14.6 years (range, 32-83 years). The choroidal tumor group included six choroidal metastases and four choroidal melanomas. The mean follow-up period after GKR was 7.0 ± 4.3 months (range, 2-13 months). The mean cumulative marginal dose was 25.36 ± 7.35 Gy (range, 16-45 Gy). Pre- and postoperative magnetic resonance imaging revealed a reduction in tumor volume in eight of the 10 eyes and five of them presented with improved visual symptoms. One patient showed increased tumor volume; however, a new choroidal lesion was not observed. Another patient showed no reduction in tumor size; however, the pain had worsened, and the eye was enucleated. The mean maximum tumor diameter decreased from 1.60 ± 0.37 cm before to 1.22 ± 0.47 cm after GKR (p = 0.004), and the mean minimum diameter decreased from 0.62 ± 0.27 cm before to 0.38 ± 0.35 cm after GKR (p = 0.031). No radiation-induced optic neuropathy, retinopathy, or cataracts was observed in any of the cases during the follow-up period. @*Conclusions@#GKR was shown to be safe for choroidal lesions identified in orbital magnetic resonance imaging with a reduction in the size of choroidal tumors and eyeball preservation expected with this treatment approach.

ABSTRACT

Purpose@#To describe the surgical technique and clinical outcome of autologous retinal free flap transplantation for recurrent giant macular hole retinal detachment (MH RD) in a high myopia patient.Case summary: A 71-year-old female had undergone pars plana vitrectomy (PPV), internal limiting membrane peeling, and endolaser photocoagulation at the margin of the hole with silicone oil tamponade for repair of myopic MH RD. Silicone oil was removed at postoperative 4 months and the retina was properly attached. Unfortunately, the retina redetached with a large MH, which developed 8 years after surgery. The patient underwent 3-port PPV under general anesthesia. A retinal flap was harvested from the mid-periphery of the superior detached retina. The retina was cut along the marked edge of the retinal flap except for a small attachment part (hinge). After fluid-air exchange, the hinge of the retinal free flap was gently dissected and then placed on the macular area with a drop of viscoelastics. Endolaser treatment was performed around the retinal flap harvest site and silicone oil was injected at the end of surgery. The 1 week postoperative optical coherence tomography showed MH closure, which was stable at postoperative 9 months. @*Conclusions@#Autologous retinal free flap transplantation is an effective method as a surgical option for recurrent giant MH RD in high myopia patients.

ABSTRACT

Purpose@#To report the successful rehabilitation of a patient with anomalous head posture by using a virtual reality low vision aid (VRLVA).Case summary: A 75-year-old male diagnosed with age-related macular degeneration 15 years prior presented with an anomalous head posture for eccentric viewing. He had central scotoma within the central 10 degrees, and the preferred retinal locus (PRL) was localized to the inferonasal retina. The patient underwent a training session on the use of the VRLVA, which has a remapping function to remap distorted images, and those falling on the scotoma, to another location on the screen. After explaining the purpose of the VRLVA, the patient was given the device to use at home for two weeks. At two weeks after training, the patient could look straight ahead when using the VRLVA, without anomalous head posture. In addition, reading performance, including speed and accuracy, improved; moreover, he experienced no device-related adverse events. @*Conclusions@#By using the VRLVA, low-vision patients with anomalous head posture can shift images falling on the central scotoma to the PRL, thereby minimizing their anomalous head posture and improving reading performance. We expect that future technological advances, such as a wearable design and the use of lightweight material, will further improve the performance and acceptability of the VRLVA.

ABSTRACT

Purpose@#To evaluate the clinical usefulness of a low vision aid using a virtual reality device (LVA-VR) in patients with low vision. @*Methods@#Forty low vision patients were enrolled in this prospective study. All subjects participated in a two-session LVA-VR training course. The binocular best-corrected distance, intermediate, and near visual acuities (BCDVA, BCIVA, and BCNVA, respectively) were measured, along with contrast sensitivity and reading performance, at baseline and after 2 weeks of LVA-VR use. All subjects also provided a self-rated functional score (SFS) and completed a satisfaction questionnaire following the study. @*Results@#Thirty-nine subjects (mean age, 54.6 ± 22.7 years) completed the study. Significant improvements in BCDVA, BCIVA, BCNVA, and contrast sensitivity were observed after 2 weeks of LVA-VR use (p < 0.001). Reading accuracy also improved significantly (p = 0.027); however, the reading speed did not change. Subject functionality improved, as indicated by the increase in the SFS (11.8 ± 4.5 vs. 19.6 ± 5.3) (p < 0.001). Most patients were satisfied with their visual function improvement and found LVA-VR to be useful in their daily activities. No device-related adverse events were observed or indicated. @*Conclusions@#This study suggests that LVA-VR is beneficial for visual rehabilitation. Future technological advances are expected to improve LVA-VR performance and acceptability further for a better quality of life in low vision patients.

ABSTRACT

PURPOSE: To report the long-term outcome after surgical repair of a full-thickness macular hole (FTMH) in a patient with retinitis pigmentosa (RP). CASE SUMMARY: A 55-year-old male who had been diagnosed with retinitis pigmentosa in both eyes 5 years earlier presented with decreased visual acuity in his left eye over the last 6 months. On examination, his Snellen best-corrected visual acuity (BCVA) was 1.0 in the right eye and 0.3 in the left eye. Slit-lamp examination of the anterior segment was remarkable only for posterior chamber intraocular lenses in each eye. Fundus examination demonstrated extensive bony spicule-like pigmentation in the mid-peripheral region in both eyes and a FTMH with approximately one-third disc diameter in the left eye. The optical coherence tomography (OCT) findings confirmed a FTMH with a surrounding cuff of intraretinal fluid and vitreomacular traction in the left eye. The patient underwent 23-gauge pars plana vitrectomy (PPV) with indocyanine green-assisted internal limiting membrane peeling and gas tamponade. One week postoperatively, an anatomically well-sealed macular hole was confirmed by OCT. At the 3-month postoperative follow-up, the BCVA improved to 0.63 and the hole remained closed until his last follow-up (postoperative 6 years). CONCLUSIONS: Although macular hole is a rare occurrence in RP patients, it should be considered as a cause of significant visual loss in patients with this disorder. Our case suggested that over the long-term, PPV may be tolerable in the management for FTMH in RP.

ABSTRACT

PURPOSE: To introduce a new convenient and accurate method to measure the angle kappa using ultrasound biomicroscopy (UBM) and corneal topography. METHODS: Data from 42 eyes (13 males and 29 females) were analyzed in this study. The angle kappa was measured using Orbscan II and calculated with UBM and corneal topography. The angle kappa of the dominant eye was compared with measurements by Orbscan II. RESULTS: The mean patient age was 36.4 ± 13.8 years. The average angle kappa measured by Orbscan II was 3.98°± 1.12°, while the average angle kappa calculated with UBM and corneal topography was 3.19°± 1.15°. The difference in angle kappa measured by the two methods was statistically significant (p < 0.001). The two methods showed good reliability (intraclass correlation coefficient, 0.671; p < 0.001). Bland-Altman plots were used to demonstrate the agreement between the two methods. CONCLUSIONS: We designed a new method using UBM and corneal topography to calculate the angle kappa. This method is convenient to use and allows for measurement of the angle kappa without an expensive device.

ABSTRACT

PURPOSE: To report a case of migraine attacks with aura that occurred after percutaneous closure of an atrial septal defect (ASD) with the Amplatzer septal occluder device. CASE SUMMARY: A 58-year-old female presented with glare and scintillation that lasted 3 days. She had a history of percutaneous ASD intervention 3 weeks prior. Because ophthalmologic examination revealed nothing remarkable, the patient underwent observation. However, two months later, she revisited our department, presenting with aggravated glare, scintillation, and severe photophobia. Also, she presented with scintillation followed by a headache starting from the right temporal area extending to the occipital area. The patient was diagnosed with migraine with aura, which was newly developed after percutaneous ASD closure. After switching medication from acetylsalicylic acid to clopidogrel, the frequency and intensity of the headaches were reduced. No recurrence of ophthalmic symptoms or headache was observed during the 1-year follow-up. CONCLUSIONS: Percutaneous closure of ASD can be complicated by the appearance of migraine attacks with aura. When patients present with glare and scintillation, ophthalmologists must consider the possibility of migraine with aura and migraine induced by secondary causes. Thus, detailed history taking should be taken in order to make an early diagnosis of migraine.

ABSTRACT

OBJECTIVES: To assess innate and humoral immune responses in middle ear effusion of obese pediatric patients with otitis media with effusion (OME). METHODS: We evaluated 219 children with OME, of whom 21 were obese and 198 were non-obese. We compared the expression in middle ear effusion of mRNAs encoding toll-like receptors (TLR) 2, 4, 5, and 9; nucleotide-binding oligomerization domains (NOD) 1 and 2; retinoic acid-inducible gene (RIG)-I; interleukins (IL)-6, -10, and -12; interferon (IFN)-gamma; and tumor necrosis factor (TNF)-alpha mRNAs. We also compared the expression of immunoglobulins IgG, IgA, and IgM and the bacterial detection rate in the two groups. RESULTS: TLR2-mediated expression of IL-6 mRNA, TLR4-mediated expression of IL-6 and IL-10 mRNA, TLR5-mediated expression of IL-6, IL-10, and TNF-alpha mRNA, TLR9-mediated expression of IL-6 mRNA, and NOD2-mediated expression of IL-6, IL-12, and TNF-alpha mRNA were significantly lower in obese than in non-obese children (P0.05). CONCLUSION: Mean body mass index was higher and pattern-recognition receptor-mediated cytokine mRNA expression was lower in obese than in non-obese children with OME.
