Serum IgG4-negative IgG4-related disease with a cardiac mass: A case report.

RATIONALE: Although IgG4-related disease (IgG4-RD) can affect various organs, its association with a cardiac mass is exceptionally rare. Here, we report a case of a woman with IgG4-RD and a cardiac mass and discuss 10 similar cases reported previously. PATIENT CONCERNS: A 65-year-old woman was referred to our hospital for chest discomfort and back pain. DIAGNOSES: In accordance with the 2019 ACR/EULAR diagnostic criteria for IgG4-RD, she was diagnosed with IgG4-RD based on dense lymphocytic infiltration on histopathology, IgG/IgG4-positive cell ratio <40%, >10/hpf IgG4-positive cells on immunostaining, and paraspinal zone soft tissue lesions in the chest. INTERVENTIONS: An external pacemaker was implanted for the complete atrioventricular block on the electrocardiogram. After the diagnosis of IgG4-RD, she was treated with glucocorticoids and rituximab. OUTCOMES: She remains under observation without disease recurrence. LESSONS: IgG4-RD are usually treated with glucocorticoids; however, in cases of a cardiac mass, life-threatening complications may occur and surgery is often needed. Combination therapy with glucocorticoids and rituximab may be effective even in patients with IgG4-RD and cardiac mass, which may avoid the need of invasive treatments, such as surgery.

A CASE OF RAPIDLY PROGRESSIVE RETINOPATHY ASSOCIATED WITH PEMBROLIZUMAB IMMUNOTHERAPY FOR METASTATIC UROTHELIAL CARCINOMA.

PURPOSE: To describe a novel case of bilateral rapidly progressive retinopathy after immunotherapy with pembrolizumab for metastatic urothelial carcinoma. METHODS: Case report. RESULTS: A 64-year-old man undergoing pembrolizumab immunotherapy was referred to our hospital because of bilateral acute vision loss. His best-corrected visual acuity was 20/30 in the right eye and 20/320 in the left eye, and a visual field test revealed central and paracentral scotomas in the right eye and central scotoma in the left eye. We suspected immune-related retinopathy based on the progressive photoreceptor damage with abnormal electroretinogram findings, absence of overt intraocular inflammation, and presence of malignancy. Cessation of pembrolizumab and steroid pulse therapy followed by decreasing oral prednisolone improved visual function and photoreceptor damage, although there was recurrence after pembrolizumab was restarted. CONCLUSION: We reported a case of rapidly progressive retinopathy that may have been triggered by pembrolizumab immunotherapy for metastatic urothelial carcinoma. High-dose corticosteroid pulse therapy was effective in reversing photoreceptor damage.

Ten-year outcomes of cataract surgery for glaucoma management in patients with primary angle-closure disease.

PURPOSE: To investigate the long-term outcomes of cataract surgery for glaucoma management in patients with primary angle-closure disease (PACD). STUDY DESIGN: Retrospective case series. METHODS: We reviewed the medical records of 87 eyes of 87 patients with PACD who underwent uncomplicated cataract surgery alone at the Kobe City Medical Center General Hospital. Only patients with a minimum follow-up of 10 years were included. The patients were divided into PACD spectrum categories: primary angle-closure glaucoma (PACG), primary-angle closure (PAC), and primary angle-closure suspect (PACS). The treatment outcomes were compared among the 3 groups. Intraocular pressure (IOP), number of glaucoma eye drops, requirement of additional glaucoma treatment, visual field progression, and progression to glaucoma during the follow-up period were evaluated. RESULTS: Among the 87 patients, 39 had PACG; 26, PAC; and 22, PACS. Ten years after surgery, the IOP had significantly decreased from baseline in all 3 groups. The rate of requirement of additional glaucoma treatment during the follow-up period was significantly higher in the PACG group than in the other groups. Almost half of the patients with PACG required additional glaucoma treatment; of those patients, six (15.4%) underwent glaucoma surgery. Three patients (11.5%) with PAC required additional glaucoma medication. Visual field progression was observed in 28.1% of the patients with PACG. In 1 patient with PAC, the condition progressed to PACG, but there was no such progression in any of the patients with PACS. CONCLUSIONS: We confirmed that cataract surgery had a long-term (> 10 years) effect on IOP reduction in eyes with PACD. Early intervention with cataract surgery may be preferable for glaucoma management in patients with PACD.

Use of ellipsoid zone width for predicting visual prognosis after cataract surgery in patients with retinitis pigmentosa.

OBJECTIVE: To predict the visual prognosis of cataract surgery in patients with retinitis pigmentosa by measuring ellipsoid zone (EZ) width using spectral-domain optical coherence tomography. METHODS: This retrospective study included patients with retinitis pigmentosa who underwent uncomplicated cataract surgery between December 2017 and June 2020. Preoperative best-corrected visual acuity (BCVA) and the best postoperative BCVA during follow-up were collected. EZ width was measured on preoperative cross-sectional optical coherence tomography images along the horizontal/vertical meridian through the fovea. RESULTS: Thirty-eight eyes of 38 patients (22 female; mean [±standard deviation] age, 62.1 ± 11.8 years) were included. The median preoperative logarithm of the minimum angle of resolution BCVA of 0.52 (range, 0.00-3.00) significantly improved to 0.07 (range, -0.18-3.00) after surgery (P < 0.001). On preoperative spectral-domain optical coherence tomography images, the median horizontal, vertical, and average EZ widths were 783 (range, 0-9837), 761 (range, 0-10 250), and 769 (range, 0-10 043) µm, respectively. Postoperative BCVA significantly correlated with the horizontal (r = -0.784, P < 0.001), vertical (r = -0.777, P < 0.001), and average EZ widths (r = -0.777, P < 0.001). The area under the receiver operating characteristic curve for the ability of the horizontal, vertical, and average EZ widths to discriminate eyes with and without postoperative BCVA ≤ 0.3 was 0.971, 0.960, and 0.963, respectively, with best cut-off values of 513, 608, and 515 µm, respectively. CONCLUSIONS: EZ width measurement can help predict the visual prognosis of cataract surgery in patients with retinitis pigmentosa. A preferable visual acuity prognosis can be expected in patients with an EZ width of approximately 600 µm.

Performance of ChatGPT in Board Examinations for Specialists in the Japanese Ophthalmology Society.

We investigated the potential of ChatGPT in the ophthalmological field in the Japanese language using board examinations for specialists in the Japanese Ophthalmology Society. We tested GPT-3.5 and GPT-4-based ChatGPT on five sets of past board examination problems in July 2023. Japanese text was used as the prompt adopting two strategies: zero- and few-shot prompting. We compared the correct answer rate of ChatGPT with that of actual examinees, and the performance characteristics in 10 subspecialties were assessed. ChatGPT-3.5 and ChatGPT-4 correctly answered 112 (22.4%) and 229 (45.8%) out of 500 questions with simple zero-shot prompting, respectively, and ChatGPT-4 correctly answered 231 (46.2%) questions with few-shot prompting. The correct answer rates of ChatGPT-3.5 were approximately two to three times lower than those of the actual examinees for each examination set (p = 0.001). However, the correct answer rates for ChatGPT-4 were close to approximately 70% of those of the examinees. ChatGPT-4 had the highest correct answer rate (71.4% with zero-shot prompting and 61.9% with few-shot prompting) in "blepharoplasty, orbit, and ocular oncology," and the lowest answer rate (30.0% with zero-shot prompting and 23.3% with few-shot prompting) in "pediatric ophthalmology." We concluded that ChatGPT could be one of the advanced technologies for practical tools in Japanese ophthalmology.

Comparison of the Accuracy of Intraoperative Aberrometry in Intraocular Lens Implantation Between Myopic Eyes with Emmetropia and Myopia Targets.

Purpose: To compare the accuracy of intraoperative aberrometry (IA) for predicting postoperative refraction between eyes with emmetropia and myopia targets. Patients and Methods: This retrospective analysis included patients with axial myopia (axial length ≥ 25.0 mm) who underwent uncomplicated phacoemulsification cataract surgery with IA to achieve emmetropia (plano to -0.5 D) or intentional myopia (-2.5 D to -5.0 D). Preoperative ocular biometry was performed in all eyes using an IOLMaster. Refractive prediction errors in IA were compared between eyes with emmetropia and myopia targets. Refractive prediction errors in IA for both groups were also compared with those predicted by intraocular lens power calculation formulas including the SRK/T, Holladay 1, Hoffer Q, Holladay 2, Haigis, and Barrett Universal II formulas. Results: Thirty-nine eyes of 39 patients with a target of emmetropia and 22 eyes of 22 patients with a target of intentional myopia were included in the final analysis. The mean numerical error was significantly different from zero (myopic trend) in myopia-targeted eyes (-0.37 ± 0.54 D, one-sample t-test, P = 0.004, 95% confidence interval: -0.61 to -0.14), while it was close to zero in emmetropia-targeted eyes. The mean absolute error was significantly smaller in emmetropia-targeted eyes (0.28 ± 0.27 D) than in myopia-targeted eyes (0.51 ± 0.41 D, P = 0.01). IA was revealed as the most accurate method for predicting postoperative refraction in eyes with emmetropia target, whereas Barrett Universal II formula was found to be the most accurate for eyes with myopia target. Conclusion: In patients with axial myopia, the performance of IA was altered when targeting intentional myopia compared with emmetropia. Myopic shift in the refractive outcome should be considered when IA is used to target myopia.

One-year outcomes and predictable factors for microhook ab interno trabeculotomy.

AIM: To investigate the one-year outcomes and factors that influence the results of microhook ab interno trabeculotomy (µLOT). METHODS: The medical records of consecutive patients with open angle glaucoma who underwent µLOT (including combination of µLOT and cataract surgery) between February 2018 and July 2019 were retrospectively reviewed. Surgical success was defined as the following: an intraocular pressure (IOP)≤21 mm Hg or IOP≤preoperative IOP with a reduced number of glaucoma eye drops, without additional glaucoma surgery, and assessed using Kaplan-Meier survival analysis. A multivariate Cox proportional-hazards regression model was used to investigate the factors associated with surgical failure. RESULTS: The 59 eyes of 59 patients comprising 28 eyes with primary open angle glaucoma (POAG) and 31 with secondary open angle glaucoma (SOAG) were included. The mean IOP and number of glaucoma eye drops significantly decreased from 25.3±7.2 mm Hg and 3.9±1.1, preoperatively to 16.1±4.4 mm Hg (P<0.01) and 2.1±1.8 (P<0.01), respectively, 12mo postoperatively, with a cumulative success rate of 63.1%. The one-year success rate was significantly higher in POAG eyes than in SOAG eyes (80.0% vs 48.0%; P=0.011, log-rank test). Multivariate analyses revealed SOAG [P=0.017, adjusted hazard ratio (aHR): 3.468, 95%CI: 1.246-9.654] and the postoperative IOP spike (IOP>25 mm Hg within 2wk post-surgery; P<0.001, aHR: 5.382, 95%CI: 2.113-13.707) as independent factors associated with surgical failure. CONCLUSION: The µLOT is a good treatment option for POAG eyes. However, the postoperative course should be carefully followed in cases with postoperative IOP spike.

Accuracy of Intraocular Lens Power Calculation Formulas in Myopic Eyes with Target Refractions of Emmetropia and Intentional Myopia.

PURPOSE: To compare the accuracy of the intraocular lens (IOL) power calculation formulas for predicting the postoperative refraction in eyes with a target of emmetropia or intentional myopia. PATIENTS AND METHODS: This is a retrospective study conducted at Kobe City Eye Hospital, Kobe, Japan. Fifty eyes of 50 patients with axial myopia who underwent uncomplicated phacoemulsification and single-type IOL implantation for a target of emmetropia (plano to -0.5 D) or intentional myopia (-2.0 D to -3.0 D) were selected. Preoperative ocular biometry was performed using IOLMaster700 in all eyes. Refractive prediction errors of 6 IOL formulas integrated into IOLMaster700 were compared between eyes with a target of emmetropia and intentional myopia. RESULTS: The mean numerical errors of SRK/T (Sanders, Retzlaff, and Kraft/theoretical), Holladay 1, Hoffer Q, and Holladay 2 significantly differed between the two groups (p < 0.001, p = 0.008, 0.02, and 0.007, respectively). The values for mean numerical errors in eyes with a target of intentional myopia were smaller, showing relatively myopic outcome, as compared with those in eyes with a target of emmetropia. In eyes with a target of emmetropia, the mean numerical errors of Holladay 1 (p < 0.001, 95% confidence interval [CI]: 0.32 to 0.63), Hoffer Q (p = 0.001, 95% CI: 0.12 to 0.42), and Barrett Universal II (p = 0.007, 95% CI: 0.06 to 0.35) were significantly different from zero (hyperopic trend). Furthermore, in eyes with a target of intentional myopia, the mean numerical error of SRK/T (p = 0.001, 95% CI: -0.61 to -0.17) and Holladay 2 (p = 0.023, 95% CI: -0.43 to -0.04) were significantly different from zero (myopic trend). CONCLUSION: In patients with axial myopia, some IOL formulas may show a myopic trend in the refractive outcome when targeting intentional myopia as compared to emmetropia.
