Characteristics of retinal detachment associated with atopic dermatitis.

BACKGROUND: To examine the characteristics of rhegmatous retinal detachment (RRD) associated with atopic dermatitis. METHOD: Medical records of 2257 patients who underwent RD surgery at this clinic between 2008 and 2018 were retrospectively reviewed. Among them, 61 patients who were diagnosed as AD were assigned into the experimental group and 100 patients who did not have AD were randomly selected and assigned into the control group. Demographics, characteristics of detachment, initial operative method, and prognosis after surgery were investigated as main outcomes. Additionally, in pseudophakic RD patients, the period between the cataract surgery and onset of RD was measured. RESULT: Postoperative VA and prognosis were significantly worse and bilateral involvement of RD was more common in the atopy group than in the control group. (P value = 0.005, 0.001 each) Characteristics of retinal breaks were different between the two groups. Additionally, the risk of developing RD within 1 year after cataract surgery was significantly higher in pseudophakic patients of the atopic group than in the control group. (P value = 0.013) However, there was no significant difference in mean preoperative VA or refractive index between the two groups. CONCLUSION: Our results show that in atopic patients, RD occurs at a young age with different characteristics compared to non-atopic patients. Atopic RD has a poor visual prognosis. Thus, it requires careful management. Furthermore, the risk of developing RD within 1 year after cataract surgery is higher in atopic patients. Therefore, it is important to perform regular and extensive check-up after cataract surgery for atopic patients.

Clinical course after the onset of choroidal neovascularization in eyes with central serous chorioretinopathy.

ABSTRACT: Chronic central serous chorioretinopathy (CSC) can be complicated with choroidal neovascularization (CNV); however, the timing of its occurrence and its clinical significance are not well understood. This study aimed to observe the time of choroidal neovascularization detection after CSC diagnosis and determine whether clinical features and prognosis differed in patients with chronic CSC or age-related retinal degeneration.In this retrospective study, medical records of CSC patients complicated with CNV who visited Seoul St. Mary's hospital of Korea between October 2009 and December 2020 were reviewed. The presence of CNV was determined using fluorescein, indocyanine green, or optical coherent tomography angiography (OCTA). Based on the patients' medical records, we observed the change of clinical pattern, best-corrected visual acuity (BCVA) and central macular thickness (CMT) at CNV detection and at 6 months, 1 year, 3 years, and 5 years following CNV detection.Thirty eyes of 30 patients (male: female ratio of 13:17) were enrolled. Mean age at diagnosis of CSC was 54.0 ±â€Š8.5 years (mean ±â€Šstandard deviation). On average, CNV was detected 1.65 ±â€Š2.30 years after the diagnosis of CSC. The mean CMT was significantly decreased at 6 months, 1 year, and 3 years after choroidal neovascularization detection (P < .001, P < .001, P = .001 respectively). BCVA tend to improve after CNV detection, but there was no statistical significance at 6 months, 1 year, 3 years, and 5 years (all with P > .05). There were no clinical findings suggesting age-related macular degeneration such as intraretinal, subretinal hemorrhage or drusen in any of the case during follow-up. None of the subjects had severe visual acuity loss of 1.0 logarithm of the minimum angle of resolution (logMAR) (20/200 Snellen equivalent) or greater. Among the subjects, 6 patients (20%) did not require any treatment during observation, while 24 other patients required anti-vascular endothelial growth factor (anti-VEGF) or photodynamic therapy. At the last visit, 22 patients (73.3%) remained stable for more than 6 months, without subretinal fluid recurrence.Choroidal neovascularization was detected earlier than previously reported. There was no rapid deterioration of visual acuity or clinical features even after CNV detection.

Unaffected fellow eye neovascularization in patients with type 3 neovascularization: Incidence and risk factors.

PURPOSE: To evaluate the incidence and risk factors of neovascularization in unaffected fellow eyes of patients diagnosed with type 3 neovascularization in Korea. METHODS: This retrospective study included 93 unaffected fellow eyes of 93 patients diagnosed with type 3 neovascularization. For initial type 3 neovascularization diagnosis, optical coherence tomography and angiography were conducted. These baseline data were compared between patients with and without neovascularization in their fellow eyes during the follow-up period. RESULTS: The mean follow-up period was 66.1±31.1 months. Neovascularization developed in 49 (52.8%) fellow eyes after a mean period of 29.5±19.6 months. In the fellow eye neovascularization group, the incidence of soft drusen and reticular pseudodrusen was significantly higher than that in the non-neovascularization group (83.7% vs. 36.5%, p<0.001; 67.3% vs. 40.9%, p = 0.017, respectively), but the choroidal vascularity index (CVI) showed a significantly lower value (60.7±2.0% vs. 61.7±2.5%; p = 0.047). The presence of reticular pseudodrusen was related with the duration from baseline to development of fellow eye neovascularization (p = 0.038). CONCLUSION: Neovascularization developed in 52.8% of unaffected fellow eyes. The presence of soft drusen, reticular pseudodrusen, and lower CVI values can be considered risk factors of neovascularization in unaffected fellow eyes of patients with type 3 neovascularization. The lower CVI values suggest that choroidal ischemic change may affect the development of choroidal neovascularization in these patients.

A 12-week, randomized, double-blind, placebo-controlled study assessing the efficacy of EGHB010, a standardized extract of Paeoniae radix and Glycyrrhizae radix, in patients with early age-related macular degeneration.

BACKGROUND: EGHB010, a standardized extract of Paeoniae radix and Glycyrrhizae radix, inhibits choroidal neovascularization. The aim of this study is to evaluate the efficacy and safety of EGHB010 on early age-related macular degeneration (AMD) progression inhibition. METHODS: The study was designed as a randomized, double-blind, single-center, placebo-controlled study. Subjects were 50 years of age or older, and early AMD satisfied the criteria of more than 15 small (<63 µm) drusen, less than 20 intermediate (≥63, <125 µm) drusen, or pigment abnormalities. For 12 weeks, the treatment group received EGHB010 and the control received the placebo. The main outcomes were changes in macular pigment optical density (MPOD), central macular thickness (CMT), and central choroidal thickness (CCT). Subgroup analysis was performed on subjects with MPOD <0.75 at baseline. RESULTS: Forty-eight subjects out of 94 were assigned to the treatment group, and 46 to the control group. At 12 weeks, mean MPOD of the treatment group increased by 0.04±0.27 (P=0.2730), and that of the control group decreased by 0.03±0.21 (P=0.7240), but there was no significant difference between the two groups (P=0.1234). There were no significant differences between the two groups in mean CMT and CCT (P=0.6718 and 0.6608, respectively). In subgroup analysis, there were 39 subjects with MPOD <0.75 in the treatment group and 36 in the control. Mean MPOD of the treatment group significantly increased by 0.09±0.25 (P=0.0218), and there was a significant difference in mean MPOD at 12 weeks between the two groups (P=0.0248). Adverse reactions were similar in both groups, and no subjects had serious adverse events. CONCLUSIONS: EGHB010 is expected to increase MPOD when administered to subjects with MPOD <0.75. EGHB010 is worth considering as a substance that inhibits the progression of early AMD.

Serial changes in the aqueous IL-10 level after intravitreal methotrexate injection as an indicator of primary vitreoretinal lymphoma recurrence.

Primary vitreoretinal lymphoma (PVRL) often masquerades as other uveitic diseases. We investigated the aqueous cytokine level changes and the effects of intraocular methotrexate (MTX) in patients with PVRL. In this retrospective consecutive case-series study, we reviewed the records of 14 consecutive patients with PVRL treated between 2018 and 2020. The concentrations of interleukin (IL)-2, IL-6, IL-10, IL-12, IL-17, interferon (IFN)-γ, and tumor necrosis factor (TNF)-α were determined at baseline and several time points after intravitreal MTX injections during follow-up. Markedly elevated IL-10 levels and a higher IL-10/IL-6 ratio were found in patients with PVRL. The aqueous levels of IL-10, IL-12, and TNF-α, and the IL-10/IL-6 ratio significantly decreased at 1 month after intravitreal MTX therapy onset compared with the baseline values (P = 0.001, 0.002, 0.001, and 0.001, respectively). The mean duration to normalized IL-10 levels was 1.17 ± 0.4 months. Where serially recorded IL-10 levels were available, regular intravitreal MTX treatment was associated with rapid reduction in IL-10 levels, while elevated IL-10 level was associated with disease recurrence. Elevated IL-10 levels and high IL-10/IL-6 ratio may aid in the diagnosis of PVRL. Aqueous IL-10 level monitoring can help assess the therapeutic response and indicate disease recurrence.

Prognostic factors of cytomegalovirus retinitis after hematopoietic stem cell transplantation.

PURPOSE: To identify the visual prognostic factors in patients with cytomegalovirus (CMV) retinitis after hematopoietic stem cell transplantation (HSCT). METHODS: This retrospective cohort study included 4241 patients who underwent HSCT from April 1, 2010 to March 31, 2019 at Seoul St. Mary's Hospital. Of them, 1063 patients presented CMV viremia, and 67 patients (93 eyes) were diagnosed with CMV retinitis. We enrolled 66 patients (91 eyes). The main outcomes included the initial best-corrected visual acuity (BCVA), BCVA at the diagnosis of retinitis and last visit, involved retinal zone, peak CMV DNA levels in the peripheral blood and aqueous humor, time between HSCT and the diagnosis of retinitis, time between the diagnosis of viremia and retinitis, complications, recurrence, survival, and so on. RESULTS: The mean BCVA (logarithm of the minimum angle of resolution) values before HSCT, at the time of retinitis diagnosis, and at the last visit were 0.041 ± 0.076, 0.262 ± 0.529, and 0.309 ± 0.547, respectively. Multiple regression analysis revealed that the involved zone (P = 0.001), time between HSCT and retinitis diagnosis (P = 0.019), and survival status (P = 0.001) were associated with the final visual acuity. CONCLUSIONS: The final visual prognosis was worse in patients with greater invasion of the central retinal zone, those with a longer interval between HSCT and the diagnosis of retinitis, and those who died. Prompt diagnosis of CMV retinitis through periodic fundus examinations of patients with CMV viremia can prevent severe vision loss. Once CMV viremia is confirmed, we recommend fundus examinations to be immediately performed and repeated every 2 weeks for at least 2 months, even if the CMV DNA titer in the peripheral blood becomes negative.

A case of anisakiasis invading the stomach and the colon at the same time after eating anchovies.

Anisakiasis of the gastrointestinal tract is caused by the ingestion of raw fish or uncooked food infested with Anisakis larvae. A large number of cases of gastric anisakiasis have been reported in countries where the eating of raw fish is customary. However, there have been few reports of anisakiasis of the colon confirmed by colonoscopy and also very few reports of endoscopic ultrasonographic findings of anisakiasis. A 47-year-old man had epigastric pain with nausea after eating raw anchovies. Endoscopy found a living tubular structure penetrating into the lesser curvature of the stomach and the midtranseverse colon area. It was withdrawn with biopsy forceps. We report a case of anisakiasis simultaneously invading the stomach and the colon confirmed by endosopic utrasonographic findings and biopsy findings.

Enamel surface evaluation after removal of orthodontic composite remnants by intraoral sandblasting: a 3-dimensional surface profilometry study.

INTRODUCTION: The purpose of this study was to determine the utility of sandblasting to remove composite remnants after orthodontic bracket debonding. METHODS: The sample consisted of 20 human premolars extracted for orthodontic purposes. The buccal surface of each premolar was divided into 3 parts: the upper half (control surface group, CS), the lower half left (LS group), and the lower half right (SS group). A composite resin paste (volume, 5 x 3 x 1 mm3) was bonded onto the LS and SS surfaces. Then it was removed by using 1 of 2 methods: low-speed handpiece with tungsten carbide bur in the LS group and sandblasting in the SS group. Temperature change and removal time were recorded, and surface profiles were examined with 3-dimensional profilometry. RESULTS: An independent t test showed a statistically significant difference in temperature change between the LS and SS groups (P <.01). ANOVA showed no significant difference in surface profile between the LS and SS groups (P >.5). CONCLUSIONS: The results suggest that intraoral sandblasting might be an alternative to rotatory instruments for resin remnant removal after orthodontic bracket debonding.
