RESUMO
Intraocular foreign bodies (IOFBs) are critical ophthalmic emergencies that require urgent diagnosis and treatment to prevent blindness or globe loss. This study aimed to examine the various clinical presentations of IOFBs, determine the prognostic factors for final visual outcomes, establish diagnostic protocols, and update treatment strategies for patients with IOFBs. We retrospectively reviewed patients with IOFBs between 2005 and 2019. The mean age of the patients was 46.7 years, and the most common mechanism of injury was hammering (32.7%). The most common location of IOFBs was the retina and choroid (57.7%), and the IOFBs were mainly metal (76.9%). Multivariate regression analysis showed that poor final visual outcomes (<20/200) were associated with posterior segment IOFBs (odds ratio (OR) = 11.556, p = 0.033) and retinal detachment (OR = 4.781, p = 0.034). Diagnosing a retained IOFB is essential for establishing the management of patients with ocular trauma. To identify IOFBs, ocular imaging modalities, including computed tomography or ultrasonography, should be considered. Different strategies should be employed during the surgical removal of IOFBs depending on the material, location, and size of the IOFB.
RESUMO
PURPOSE: To evaluate the effect of adalimumab in pediatric uveitis and subsequent changes in anterior chamber inflammation following the inactivation of uveitis. METHODS: In this retrospective study, patients with noninfectious uveitis younger than 18 years of age who were treated with adalimumab for more than 12 months were included. The rate of complete suppression and the relapse in anterior chamber inflammation following the initiation of adalimumab therapy were evaluated using anterior chamber cell score and laser flare photometry (LFP) values, if available. Changes in visual acuity and the sparing effect of topical steroid agents were also evaluated. RESULTS: Among 22 eyes of 12 pediatric uveitis patients enrolled, 13 eyes were associated with juvenile idiopathic arthritis and nine eyes had idiopathic uveitis. The mean ± standard deviation age was 10.2 ± 3.6 years. Types of uveitis included anterior uveitis (n = 17) and panuveitis (n = 5). Quiescence was observed in 14 eyes (63.6%) at 3 months and in 21 eyes (95.5%) at 12 months after initiation, respectively. After achieving inactive uveitis, uveitis relapsed in two eyes at 6 months, even with adalimumab treatment. In 11 eyes, anterior chamber showed 0.5+ cell scores during the rest of the follow-up period and one of those eyes met the criteria for the relapse based on LFP values. The dosage of topical steroids decreased significantly at 3, 9, and 12 months after the initiation of therapy (p ≤ 0.05). Visual acuity did not show improvement. There were no severe adverse effects of anti-tumor necrosis factor-α treatment reported. CONCLUSIONS: In this study, adalimumab achieved a quiescent state in most eyes with pediatric noninfectious uveitis for 12 months with a relapse rate of 9.5%. LFP values together with the anterior chamber cell score can be utilized to monitor the improvement or relapse in anterior chamber inflammation in pediatric noninfectious uveitis.

PURPOSE: To develop a new classification system for vitreomacular traction (VMT) syndrome according to spectral-domain optical coherence tomography (SD-OCT) imaging and to investigate the clinical course of VMT patients. METHODS: This study included 68 eyes of 68 consecutive patients who were followed with observation or treated with vitrectomy for idiopathic VMT. Eyes were classified into one of three groups according to SD-OCT findings: group A (foveal pseudocyst, which was defined as the formation of cystoid cavity located in the inner part of the central fovea along with foveal thickening), group B (parafoveal retinoschisis, which was defined as intraretinal cysts or clefts along with no apparent foveal thickening), and group C (outer retinal dehiscence at the fovea, which is sometimes accompanied by foveal thinning). The minimum required follow-up period was 1 year. Clinical course and anatomical and functional outcomes were compared among the groups. RESULTS: Twenty-seven eyes (39.7%) were included in group A, 22 eyes (32.4%) were included in group B, and 19 eyes (27.9%) were included in group C. Among the 24 eyes that were managed by observation, a significantly larger percentage of patients in group A (6/10 [60%]) exhibited more spontaneous resolution of VMT compared with those in groups B (9.1%) or C (0%) (P = 0.010). In the 44 eyes that were managed with vitrectomy, a significantly larger percentage of patients in group C (4/16 [25%]) experienced subsequent full-thickness macular hole development following vitrectomy compared with those in groups B (0%) or C (0%) (P = 0.014). The percentage of patients with photoreceptor inner segment/outer segment disruption was significantly reduced in group A after vitrectomy, with group C exhibiting the lowest recovery rate. Postoperatively, group A experienced a significantly better visual outcome than group C (P = 0.021). CONCLUSIONS: A novel configuration system offering insight into the clinical course of VMT is proposed. According to this system, anatomical and functional outcomes were favorable in group A and worse in group C.

PURPOSE: To estimate the familial correlation and heritability of refractive error in general Korean population. METHODS: From the Korea National Health and Nutrition Examination Survey, 13 258 subjects of 7920 families, who were aged ≥19 years, were included in the study. Using variance components analysis, the additive genetic effect, or heritability, and the common and unique environmental effects on refractive error were examined, adopting common environments shared by cohabiting family or by siblings. RESULTS: The proportions of hyperopia, myopia and high myopia in Koreans were 0.8%, 45.2% and 5.7% respectively. The correlation coefficients of spherical equivalent (SE) were 0.257 for parent-offspring pairs, 0.410 for sibling pairs and 0.112 for spouse pairs (p < 0.001 for all). Common environment shared by siblings affected the variation of SE significantly (p < 0.001), but that shared by cohabitants did not (p = 0.395). Adopting common environment shared by siblings, the heritability, common environmental effect and unique environmental effect of refractive error were 42.1 ± 3.3%, 11.8 ± 3.5% and 46.1 ± 3.9% respectively. Heritabilities of hyperopia, myopia and high myopia were 45.7%, 44.3% and 68.9% respectively. Adjusted odds ratios of myopia among offspring were 3.78 given one parent has myopia and 4.43 when both parents have myopia. CONCLUSION: Refractive error is influenced by common environment shared by siblings. The heritability of refractive error is higher for high myopia than for myopia or hyperopia.

Resolution of inflammation is an active process that leads to tissue homeostasis and involves multiple cellular and molecular mechanisms. Myeloid-derived suppressor cells (MDSCs) have recently emerged as important cellular components in the resolution of inflammation because of their activities to suppress T cell activation. In this article, we show that HLA-DR-CD11b+CD33+CD14+ human MDSCs and CD11b+Ly6G-Ly6C+ mouse MDSCs markedly increased in patients and mice during and before the resolution phase of autoimmune uveoretinitis. CD11b+Ly6C+ monocytes isolated from autoimmune uveoretinitis mice were able to suppress T cell proliferation in culture, and adoptive transfer of the cells accelerated the remission of autoimmune uveoretinitis in mice. Alternatively, depletion of CD11b+Ly6C+ monocytes at the resolution phase, but not CD11b+Ly6G+ granulocytes, exacerbated the disease. These findings collectively indicate that monocytic MDSCs serve as regulatory cells mediating the resolution of autoimmune uveoretinitis.

PURPOSE: To evaluate the rate of progressive macular ganglion cell-inner plexiform layer (GCIPL) thinning in patients with open-angle glaucoma (OAG) who had been treated with intravitreal antivascular endothelial growth factor (VEGF) injection for wet age-related macular degeneration (AMD). METHODS: This study was a retrospective modified case control study with fellow eye comparison. We enrolled bilateral OAG patients who had been treated with repeated anti-VEGF injections for unilateral wet AMD and followed-up on for a minimum of 24 months by Cirrus high-definition optical coherence tomography. The rate of macular GCIPL thinning was determined by linear regression of serial optical coherence tomography GCIPL thickness measurements over time. We compared the rate of macular GCIPL thinning between anti-VEGF-treated eyes and fellow untreated dry AMD eyes. RESULTS: This study involved 32 OAG eyes of 16 subjects. The total follow-up period was 58.4±25.5 (24 to 98) months, and the mean number of anti-VEGF injections was 10.6±10.4 (3 to 40). The eyes with repeated anti-VEGF treatment differed significantly from their fellow eyes in the rate of GCIPL thinning (-2.95±3.58 vs. -0.77±0.95 µm/y, P=0.015). Also, multivariable regression analyses showed that anti-VEGF injection was significantly associated with the rate of GCIPL thinning (P=0.025). CONCLUSIONS: In subjects with bilateral OAG, the rate of GCIPL thinning is significantly faster in eyes treated with anti-VEGF injection for wet AMD than in untreated dry AMD fellow eyes. This finding suggests that in glaucomatous eyes, VEGF inhibition could play a role, at least in part, in progressive change of inner retinal layers.

PURPOSE: To analyze risk factors and management of pupillary intraocular lens (IOL) capture after IOL transscleral fixation. SETTING: Department of Ophthalmology, Seoul National University Hospital, Seoul, South Korea. DESIGN: Retrospective case series. METHODS: A chart review was performed of patients who had transscleral fixation of IOLs between January 1, 2012, and December 31, 2013. Eyes were divided into 2 groups depending on whether the IOL was pupillary captured. Perioperative corrected distance visual acuity (CDVA), intraocular pressure (IOP), spherical equivalent (SE) with refraction, axial length (AL), and total follow-up time were compared between the 2 groups. Ultrasound biomicroscopy images were used to analyze iris morphology and IOL position. RESULTS: The chart review identified 138 patients, 112 patients of whom were included in this analysis. The preoperative and final mean CDVA, IOP, SE, AL, and most iris morphologic parameters were not significantly different between the 2 groups. In the pupillary capture IOL group, the mean age of patients with was younger, the anterior chamber depth (ACD) was narrower, and the rate of reverse pupillary block was higher (P = .003, P = .03, and P = .016, respectively). Intraocular lens decentration in the captured group was significantly larger (P = .002). Multiple logistic regression analysis showed that ACD, reverse pupillary block, and main decentration were associated with pupillary capture of the IOL. CONCLUSIONS: Pupillary capture of an IOL occurred more in eyes with reverse pupillary block and poor IOL positioning. Accordingly, laser iridotomy must be considered for treatment.

PURPOSE: To investigate the efficacy and safety of fluocinolone acetonide intravitreal implant in patients with Vogt-Koyanagi-Harada disease. METHODS: A post hoc, subgroup analysis on patients with Vogt-Koyanagi-Harada was performed using data sets from two multicenter randomized trials on fluocinolone acetonide implant. Each subject received fluocinolone acetonide implantation in one eye and standard-of-care treatment in the fellow eye and was followed for 3 years. RESULTS: Thirty patients were included with the mean age of 38.5 years. The cumulative rate of uveitis recurrence for 3 years was significantly reduced in implanted eyes compared with fellow eyes (33 vs. 87%; P < 0.001). The reduction of daily corticosteroid dose was well maintained (12.8 mg before implantation vs. 3.7 mg after implantation; P = 0.001), but final vision was similar to preoperative vision in the implanted eyes (P = 0.082) and in the fellow eyes (P = 0.187). Postoperative elevation of intraocular pressure was more frequent in the implanted eyes than in the fellow eyes (70 vs. 20%; P < 0.001). Cataract progression occurred in all phakic implanted eyes. CONCLUSION: Fluocinolone acetonide intravitreal implant reduced uveitis recurrence rate and the dosage of systemic corticosteroid and immunosuppressant requirement in patients with Vogt-Koyanagi-Harada. However, cataract and intraocular pressure elevation developed frequently.

PURPOSE: To identify factors associated with the recovery of foveal photoreceptor disruption in eyes with an impending macular hole (MH) with vitreomacular traction syndrome after surgery. METHODS: This study comprised 33 consecutive patients who underwent vitrectomy for Stage 1 impending macular hole with disrupted photoreceptor inner segment/outer segment (IS/OS) layer and were followed up for a minimum of 1 year after surgery. Preoperative optical coherence tomography (OCT) parameters were compared between eyes that achieved complete restoration of the IS/OS layer (Group A) and those that did not (Group B). Postoperative serial changes in best-corrected visual acuity (BCVA) and IS/OS disrupted length were also investigated. RESULTS: Smooth and symmetric foveolar contour was restored in 29 eyes (87.9%). Complete recovery of IS/OS disruption was observed in 11 of 33 cases (33.3%, Group A). Group A exhibited a larger percentage of foveal pseudocysts (54.5% vs. 13.6%, P = 0.033) and a smaller mean aperture size (102.1 ± 182.1 µm vs. 241.5 ± 163.8 µm, P = 0.031) than Group B. Postoperatively, Group A revealed a significantly better visual outcome than Group Be, which was the same as Group B, but with the four eyes that developed a full-thickness macular hole excluded. CONCLUSION: Restoration of the foveal photoreceptor layer was more likely to occur in eyes with a foveal pseudocyst and smaller aperture size.

Autoimmune uveitis is one of the leading causes of blindness. We here investigated whether intraperitoneal administration of human mesenchymal stem/stromal cells (hMSCs) might prevent development of experimental autoimmune uveitis (EAU) in mice. Time course study showed that the number of IFN-γ- or IL-17-expressing CD4(+) T cells was increased in draining lymph nodes (DLNs) on the postimmunization day 7 and decreased thereafter. The retinal structure was severely disrupted on day 21. An intraperitoneal injection of hMSCs at the time of immunization protected the retina from damage and suppressed the levels of proinflammatory cytokines in the eye. Analysis of DLNs on day 7 showed that hMSCs decreased the number of Th1 and Th17 cells. The hMSCs did not reduce the levels of IL-1ß, IL-6, IL-12, and IL-23 which are the cytokines that drive Th1/Th17 differentiation. Also, hMSCs did not induce CD4(+)CD25(+)Foxp3(+) cells. However, hMSCs increased the level of an immunoregulatory cytokine IL-10 and the population of IL-10-expressing B220(+)CD19(+) cells. Together, data demonstrate that hMSCs attenuate EAU by suppressing Th1/Th17 cells and induce IL-10-expressing B220(+)CD19(+) cells. Our results support suggestions that hMSCs may offer a therapy for autoimmune diseases mediated by Th1/Th17 responses.

PURPOSE: To examine the association between female reproductive factors and age-related macular degeneration (AMD) in postmenopausal women. DESIGN: Nationwide population-based cross-sectional study. METHODS: A nationally representative dataset acquired from the 2010-2012 Korea National Health and Nutrition Examination Survey was analyzed. The dataset involved information for 4,377 postmenopausal women aged ≥50 years with a fundus photograph evaluable for AMD in either eye. All participants were interviewed using standardized questionnaires to determine reproductive factors including menstruation, pregnancy, parity, lactation, and hormonal use. The association between reproductive factors and each type of AMD was investigated. RESULTS: The mean age of the study participants was 63.1±0.2 years. Mean ages at menarche and menopause were 16.1±0.0 and 49.2±0.1 years, respectively. The overall prevalence rates of early and late AMD were 11.2% (95% confidence interval [CI], 10.1-12.5) and 0.8% (95% CI, 0.5-1.2), respectively. When adjusted for age, neither smoking nor alcohol use was associated with the presence of any AMD or late AMD. Multivariate logistic regression analysis revealed age (OR, 1.12 per 1 year), duration of lactation (OR, 0.91 per 6 months), and duration of use of oral contraceptive pills (OCP) (OR, 1.10 per 6 months) as associated factors for late AMD. The other variables did not yield a significant correlation with the risk of any AMD or late AMD. CONCLUSION: After controlling for confounders, a longer duration of lactation appeared to protect against the development of late AMD. A longer duration of OCP use was associated with a higher risk of late AMD.

PURPOSE: To investigate the clinical features, clinical course of granuloma, serologic findings, treatment outcome, and probable infection sources in adult patients with ocular toxocariasis (OT). METHODS: In this retrospective cohort study, we examined 101 adult patients diagnosed clinically and serologically with OT. Serial fundus photographs and spectral domain optical coherence tomography images of all the patients were reviewed. A clinic-based case-control study on pet ownership, occupation, and raw meat ingestion history was performed to investigate the possible infection sources. RESULTS: Among the patients diagnosed clinically and serologically with OT, 69.6% showed elevated immunoglobulin E (IgE) levels. Granuloma in OT involved all retinal layers and several vitreoretinal comorbidities were noted depending on the location of granuloma: posterior pole granuloma was associated with epiretinal membrane and retinal nerve fiber layer defects, whereas peripheral granuloma was associated with vitreous opacity. Intraocular migration of granuloma was observed in 15 of 93 patients (16.1%). Treatment with albendazole (400 mg twice a day for 2 weeks) and corticosteroids (oral prednisolone; 0.5-1 mg/kg/day) resulted in comparable outcomes to patients on corticosteroid monotherapy; however, the 6-month recurrence rate in patients treated with combined therapy (17.4%) was significantly lower than that in patients treated with corticosteroid monotherapy (54.5%, P=0.045). Ingestion of raw cow liver (80.8%) or meat (71.2%) was significantly more common in OT patients than healthy controls. CONCLUSIONS: Our study discusses the diagnosis, treatment, and prevention strategies for OT. Evaluation of total IgE, in addition to anti-toxocara antibody, can assist in the serologic diagnosis of OT. Combined albendazole and corticosteroid therapy may reduce intraocular inflammation and recurrence. Migrating feature of granuloma is clinically important and may further suggest the diagnosis of OT. Clinicians need to carefully examine comorbid conditions for OT. OT may be associated with ingestion of uncooked meat, especially raw cow liver, in adult patients.

BACKGROUND: To compare the long-term efficacy of ranibizumab versus bevacizumab for myopic choroidal neovascularization (CNV). METHODS: This was a retrospective, multicenter, comparative, non-randomized study of 64 consecutive patients with myopic CNV treated with ranibizumab (22 patients) or bevacizumab (42 patients). Best-corrected visual acuity (BCVA) and central foveal thickness (CFT) on optical coherence tomography were evaluated before and after treatment. All the patients were followed for at least 12 months. RESULTS: BCVA (logarithm of the minimal angle of resolution) improved from 0.63 ± 0.30 to 0.43 ± 0.27, 0.41 ± 0.37, 0.40 ± 0.39, 0.39 ± 0.43, and 0.39 ± 0.42 at 1, 2, 3, 6, and 12 months after treatment in the ranibizumab group, and from 0.67 ± 0.28 to 0.52 ± 0.31, 0.49 ± 0.31, 0.47 ± 0.31, 0.42 ± 0.32, and 0.46 ± 0.43 in the bevacizumab group (all P < 0.05 compared with baseline BCVA in each group). CFT decreased by 20.21%, 19.58%, and 22.43% from the baseline 304 ± 76 µm at 3, 6, and 12 months after treatment in the former group, and by 15.20%, 15.67%, and 15.56% from the baseline 297 ± 62 µm in the latter group (all P < 0.05 compared with baseline CFT in each group). BCVA improvement and CFT reduction did not statistically differ when compared at the same periods from treatment between 2 groups. Neither ocular nor systemic safety problems appeared during follow up. CONCLUSIONS: This study showed a similar functional and anatomical improvement after treatment of ranibizumab and bevacizumab for myopic CNV over a 12-month follow-up period.

PURPOSE: We examined the epidemiological association between systemic diseases and age-related macular degeneration (AMD) in the general Korean population. METHODS: This cross-sectional study involved nationally representative data obtained from the 2008 to 2011 Korea National Health and Nutrition Examination Surveys. A total of 14,352 subjects aged ≥40 years participated in standardized health interviews regarding physician-diagnosis of several systemic diseases as well as physical examinations, including fundus photography for the evaluation of AMD. RESULTS: The overall prevalence rates of early, late, and any AMD were 6.0%, 0.6%, and 6.6%, respectively. In univariate logistic regression analyses adjusted for age and sex as well as smoking in late AMD, any AMD and late AMD were less prevalent among diabetic patients and more prevalent in participants with a history of liver cancer. A history of liver cirrhosis was associated with a higher prevalence of any AMD. In the final multivariate model, the associated factors for any AMD included age (odds ratio [OR], 1.09), the presence of diabetes mellitus (DM; OR, 0.74), and a history of liver cancer (OR, 4.32). Factors associated with late AMD included age (OR, 1.09), ever-smoking history (OR, 2.45), the presence of DM (OR, 0.22), and a history of liver cancer (OR, 12.51). The presence of diabetic retinopathy was associated with a lower prevalence of any AMD (OR, 0.35). CONCLUSIONS: When adjusted for confounders, any AMD and late AMD were less prevalent in diabetic patients. In contrast, a history of liver cancer was associated with a higher prevalence of any AMD and late AMD.

PURPOSE: To evaluate the outcome of corneal allotransplantation in combined penetrating keratoplasty and vitreoretinal surgery using a temporary keratoprosthesis, and to determine the factors affecting corneal allograft survival. METHODS: We reviewed the medical charts of eleven patients who had undergone combined corneal allotransplantation and pars plana vitrectomy using an Eckardt temporary keratoprosthesis, for the treatment of corneal opacification and vitreoretinal disease. The survival rates of the corneal grafts were assessed, and patient demographics, the diagnosis of corneal and retinal disease, the preoperative ocular characteristics, and surgical methods were compared between the group with graft survival and that with graft failure. RESULTS: The causes of corneal opacification were corneal laceration (four eyes), infectious keratitis (four eyes), atopic keratitis (one eye), rejected corneal graft (one eye), and uveitis-related bullous keratopathy (one eye). The preoperative diagnoses included endophthalmitis (six eyes), posterior uveitis (one eye), vitreous opacity or hemorrhage (two eyes), and rhegmatogenous retinal detachment (two eyes). The survival rate of the corneal allografts was 27.3% (3/11 eyes). The mean survival time was 391 days during the mean follow-up period of 687 days. The retinal surgery was successful in 81.8% (9/11 eyes) of cases. The presence of active inflammation in the cornea at the time of surgery was significantly correlated with graft rejection (P=0.004). Other factors, including age, the presence of glaucoma, type of corneal and retinal disease, or type of retinal surgery, such as silicone oil injection and gas tamponade, had no significant correlation with graft rejection. CONCLUSION: Combined corneal allotransplantation and pars plana vitrectomy using a temporary keratoprosthesis allowed for successful surgical intervention in vitreoretinal disease. However, only 27.3% of corneal allografts survived, depending on the presence of active inflammation in the cornea.
RESUMO
PURPOSE: To investigate the prevalence and risk factors of age-related macular degeneration (AMD) in the general Korean adult population. METHODS: The study involved a nationally representative Korean population from the 2010 to 2011 Korea National Health and Nutrition Examination Survey. A total of 7899 subjects ≥ 40 years old participated in health interviews, physical examinations, and ophthalmologic assessment including fundus photography. RESULTS: The overall prevalence of early AMD was estimated at 6.7% (95% confidence interval [CI], 6.1-7.4), and that of late AMD was estimated at 0.7% (95% CI, 0.5-0.9), which included 0.5% prevalence of neovascular AMD and 0.2% prevalence of geographic atrophy. The prevalence rates of early and late AMD among participants aged ≥ 65 years were 16.9% and 1.8%, respectively. Hyperopia was positively associated with the presence of any AMD type (odds ratio [OR], 1.08 for every 1 diopter increase). In multivariate analyses, significant risk factors for the presence of any AMD type were age, serum high-density lipoprotein (HDL) level, serum gamma-glutamyl transferase (GGT) level, and hepatitis B surface antigen (HBsAg) serum positivity (OR, 2.26). The risk factors for late AMD included age, ever-smoking history (OR, 2.18), serum GGT level, and systolic blood pressure. CONCLUSIONS: The prevalence of AMD in Korea was similar to the prevalence of pooled Asian and Western populations. Age and serum GGT level were strongly associated with both the presence of any AMD and late AMD. Additionally, serum HDL level, HBsAg serum positivity, ever-smoking history, and systolic blood pressure were identified as risk factors for AMD.

We report a case of cytomegalovirus (CMV) retinitis after intravitreal bevacizumab injection. A 61-year-old woman with diabetic macular edema developed dense vitritis and necrotizing retinitis 3 weeks after intravitreal bevacizumab injection. A diagnostic vitrectomy was performed. The undiluted vitreous sample acquired by vitrectomy was analyzed by polymerase chain reaction and culture. Polymerase chain reaction of the vitreous was positive for CMV DNA. Other laboratory results did not show evidence of other infectious retinitis and systemic immune dysfunction. Human immunodeficiency virus antibodies were also negative. After systemic administration of ganciclovir, retinitis has resolved and there has been no recurrence of retinitis during the follow-up period of 12 months. Ophthalmologists should be aware of potential risk for CMV retinitis after intravitreal bevacizumab injection.
