Decades of stability of conjunctival vascular malformations in two patients. Clin Case Rep 2024; 12:e8933. [PMID: 38741673 PMCID: PMC11089082 DOI: 10.1002/ccr3.8933] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/05/2024] [Revised: 04/14/2024] [Accepted: 05/01/2024] [Indexed: 05/16/2024] Open
Abstract
Key Clinical Message Conjunctival hemangioma and lymphangioma are rare and their long-term follow-up description has been scarce. In our two patients, conjunctival vascular and lymphatic malformations remained stable in decades and could be observed without treatment. Abstract A 65-year-old woman with diabetic retinopathy underwent glaucoma surgery to construct a filtering bleb adjacent to conjunctival hemangioma, and showed bleb function and stable hemangioma for a decade. A 1.5-year-old girl with right eye lid and cheek swelling by orbital to facial lymphangioma was followed for visual acuity development. Conjunctival lymphangioma was stable in 20 years.

Spontaneous regression and rare relapse after excisional biopsy in long-term observation of 31 patients with primary conjunctival lymphoma. J Clin Exp Hematop 2024:24002. [PMID: 38684405 DOI: 10.3960/jslrt.24002] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 05/02/2024] Open
Abstract
To elucidate long-term outcome in primary conjunctival lymphoma, a review was conducted of 31 consecutive patients: 21 men and 10 women with an age range of 28 to 85 (median, 61) years at presentation and follow-up periods ranging from 1 to 19 (median, 7) years. Conjunctival lymphoma was on the right side in 10 patients, on the left side in 12, and on both sides in 9. Upper, lower, or both fornix lesions in 28 patients were all diagnosed as extranodal marginal zone B-cell lymphoma of mucosa-associated lymphoid tissue (MALT lymphoma), while thick nasal bulbar conjunctival lesions in 3 patients were differently diagnosed as MALT lymphoma, diffuse large B-cell lymphoma, and follicular lymphoma, respectively. Seven patients underwent local radiation (30 Gy): as initial treatment in 5 patients and treatment for relapse in 2 patients. The remaining 24 patients were observed without additional treatment after excisional biopsy: 5 of these 24 patients showed relapse 0.5 to 6 years later and underwent excisional biopsy again that revealed MALT lymphoma. Of the 5 patients with relapse, only one with second-time relapse underwent radiation. Fluorodeoxyglucose positron emission tomography was performed in 18 patients and showed no systemic lesions: high uptake was noted in the residual conjunctival lesions of 4 patients and in the relapsed conjunctival lesions of 3 patients. One patient died of rectal cancer while no patients died of lymphoma. Observation is an option in patients with primary conjunctival lymphoma after excisional biopsy. Radiation is a treatment option in the case of relapse.

Abstract
Key Clinical Message Systemic prednisolone including steroid pulse therapy would be safe in 32 pregnant women, who developed Vogt-Koyanagi-Harada disease in the literature. Prednisolone administration would be shortened by monitoring of serous retinal detachment with optical coherence tomography. Abstract A 30-year-old woman in 31 weeks of pregnancy with metamorphopsia and headache was diagnosed Vogt-Koyanagi-Harada disease. She underwent steroid pulse therapy and oral prednisolone 20 mg daily for 3 weeks until complete resolution of serous retinal detachment monitored by optical coherence tomography. Oral prednisolone was tapered and discontinued until uneventful delivery.

Abstract
Strabismus, a neuro-ophthalmological condition characterized by misalignment of the eyes, is a common ophthalmic disorder affecting both children and adults. In our previous study, we identified the microsomal glutathione S-transferase 2 (MGST2) gene as one of the potential candidates for comitant strabismus susceptibility in a Japanese population. The MGST2 gene belongs to the membrane-associated protein involved in the generation of pro-inflammatory mediators, and it is also found in the protection against oxidative stress by decreasing the reactivity of oxidized lipids. To look for the roles of the MGST2 gene in the development, eye alignment, and overall morphology of the eye as the possible background of strabismus, MGST2 gene knockout (KO) mice were generated by CRISPR/Cas9-mediated gene editing with guide RNAs targeting the MGST2 exon 2. The ocular morphology of the KO mice was analyzed through high-resolution images obtained by a magnetic resonance imaging (MRI) machine for small animals. The morphometric analyses showed that the height, width, and volume of the eyeballs in MGST2 KO homozygous mice were significantly greater than those of wild-type mice, indicating that the eyes of MGST2 KO homozygous mice were significantly enlarged. There were no significant differences in the axis length and axis angle. These morphological changes may potentially contribute to the development of a subgroup of strabismus.

Rare Combination of Abducens Nerve Palsy and Optic Neuritis on the Same Side: Case Report and Review of 8 Patients in Literature. J Investig Med High Impact Case Rep 2024; 12:23247096231225873. [PMID: 38243406 PMCID: PMC10799605 DOI: 10.1177/23247096231225873] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/30/2023] [Revised: 12/15/2023] [Accepted: 12/23/2023] [Indexed: 01/21/2024] Open
Abstract
The concurrent development of abducens nerve palsy and optic neuritis on the same side is rare. Here we presented an 82-year-old man who developed the combination of abducens nerve palsy and optic neuritis on the left side 2 months after the sixth inoculation of COVID-19 mRNA vaccine. In past history at 45 years old, he experienced subarachnoid hemorrhage and underwent surgery for the clipping of intracranial aneurysm. The patient had no systemic symptoms, such as general fatigue, fever, arthralgia, and skin rashes. Physical and neurological examinations were also unremarkable. Since the aneurysmal metal clip used at that time was not compatible with magnetic resonance imaging, he underwent computed tomographic (CT) scan of the head and showed no space-occupying lesion in the orbit, paranasal sinuses, and brain. As an old lesion, the anterior temporal lobe on the left side had low-density area with metallic artifact on the left side of the skull base, indicative of metal clipping. In 4 weeks of observation from the initial visit, he showed complete recovery of visual acuity and became capable of abducting the left eye in full degrees. We also reviewed 8 patients with the combination of abducens nerve palsy and optic neuritis in the literature to reveal that the combination of signs did occur in mild meningitis with rare infectious diseases and in association with preceding herpes zoster in the first branch of the trigeminal nerve. The course of the present patient suggested that the combination of signs might be vaccine-associated.

Abstract
Periodontal diseases are well-known background for infective endocarditis. Here, we show that pericardial effusion or pericarditis might have origin also in periodontal diseases. An 86-year-old man with well-controlled hypertension and diabetes mellitus developed asymptomatic increase in pericardial effusion. Two weeks previously, he took oral new quinolone antibiotics for a week because he had painful periodontitis along a dental bridge in the mandibular teeth on the right side and presented cheek swelling. The sputum was positive for Streptococcus species. He was healthy and had a small volume of pericardial effusion for the previous 5 years after drug-eluting coronary stents were inserted at the left anterior descending branch 10 years previously. The differential diagnoses listed for pericardial effusion were infection including tuberculosis, autoimmune diseases, and metastatic malignancy. Thoracic to pelvic computed tomographic scan demonstrated no mass lesions, except for pericardial effusion and a small volume of pleural effusion on the left side. Fluorodeoxyglucose positron emission tomography disclosed many spotty uptakes in the pericardial effusion. The patient denied pericardiocentesis, based on his evaluation of the risk of the procedure. He was thus discharged in several days and followed at outpatient clinic. He underwent dental treatment and pericardial effusion resolved completely in a month. He was healthy in 6 years until the last follow-up at the age of 92 years. We also reviewed 8 patients with pericarditis in association with periodontal diseases in the literature to reveal that periodontal diseases would be the background for developing infective pericarditis and also mediastinitis on some occasions.

Abstract
Key Clinical Message It is important to stain acid-fact bacilli on the smear of abscess puncture in addition to Gram stain to detect nontuberculous and tuberculous mycobacteria in the early phase since both can cause rare and challenging extrapulmonary manifestations. Abstract A 56-year-old otherwise healthy woman developed abscess from dacryocystitis in the right lower eyelid. The smear of puncture fluid showed acid-fast bacilli and Mycobacterium abscessus was identified after a month. The early start of clarithromycin/ethambutol was switched to clarithromycin/levofloxacin. Debridement specimen after 7-month treatment showed granulomatous tissue with no bacilli.

Abstract
Key Clinical Message Patients with antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis, specifically with myeloperoxidase (MPO)-ANCA, would have a risk for developing corneal melt and perforation abruptly in a short period. It is desirable to have a team of collaboration of rheumatologists and other specialties. Abstract An 80-year old man who had been diagnosed 5.5 years previously as ANCA-associated vasculitis by temporal artery biopsy developed corneal melt and perforation with scleritis in both eyes. He underwent successful cataract surgery and retained ambulatory vision with the aid of intravenous rituximab. Two additional patients with similar manifestations were found in the literature.

Abstract
NK-4 plays a key role in the treatment of various diseases, such as in hay fever to expect anti-allergic effects, in bacterial infections and gum abscesses to expect anti-inflammatory effects, in scratches, cuts, and mouth sores from bites inside the mouth for enhanced wound healing, in herpes simplex virus (HSV)-1 infections for antiviral effects, and in peripheral nerve disease that causes tingling pain and numbness in hands and feet, while NK-4 is used also to expect antioxidative and neuroprotective effects. We review all therapeutic directions for the cyanine dye NK-4, as well as the pharmacological mechanism of NK-4 in animal models of related diseases. Currently, NK-4, which is sold as an over-the-counter drug in drugstores, is approved for treating allergic diseases, loss of appetite, sleepiness, anemia, peripheral neuropathy, acute suppurative diseases, wounds, heat injuries, frostbite, and tinea pedis in Japan. The therapeutic effects of NK-4's antioxidative and neuroprotective properties in animal models are now under development, and we hope to apply these pharmacological effects of NK-4 to the treatment of more diseases. All experimental data suggest that different kinds of utility of NK-4 in the treatment of diseases can be developed based on the various pharmacological properties of NK-4. It is expected that NK-4 could be developed in more therapeutic strategies to treat many types of diseases, such as neurodegenerative and retinal degenerative diseases.

Abstract
A 41-year-old woman showed a palpable mass at the superonasal orbital edge on the right side. Magnetic resonance imaging demonstrated a lobulated fluid-containing tubular mass which extended anteriorly to posteriorly along the medial orbital wall, nasal to the eyeball. She was followed once a year for 8 years until the age of 49 years when she decided to undergo surgical resection because of the enlarged mass. The lobulated large mass was resected and the pathology showed sparsely distributed spindle cells, positive for CD34, in alcian blue-positive mucous substances, indicative of myxoma. Postoperative magnetic resonance imaging showed residual lobulated tubular mass along the optic nerve on the medial side and superior to the eyeball. The residual orbital mass showed stable structure with more evident connection with the ethmoid sinus lesion, suggestive of the ethmoid origin, in 12 years until the age of 61 years. In the review of 20 patients with orbital myxomas in the literature, in addition to this case, roughly classified locations in the orbit were retrobulbar in 8 patients, on the lateral side of the orbit in 4, on the superior side in 6, on the medial side in 1 (this patient), and in the orbit with no specific description in 2. In pathological examinations, immunohistochemistry was not done in 8 patients, done but all negative in 2, and positive in 11 patients: nerve sheath myxoma was diagnosed in 3 patients based on positive S100 staining. Orbital myxoma is rare but considered in differential diagnosis of orbital masses.

Abstract
Either optic neuritis (neuropathy) or hypopituitarism has been known to occur separately after COVID-19 vaccination. In this report, we describe the rare combination of hypophysitis and optic neuritis which occurred after COVID-19 vaccination. A 74-year-old woman began to have thirst, polydipsia, and polyuria, and was diagnosed as central diabetes insipidus 1 month after the fourth COVID-19 mRNA vaccine. Head magnetic resonance imaging (MRI) disclosed the thickened pituitary stalk and enlarged pituitary gland with high contrast enhancement as well as the absence of high-intensity signals in the posterior pituitary lobe on the T1-weighted image, leading to the diagnosis of lymphocytic hypophysitis. She was well with desmopressin nasal spray until further 2 months later, when she developed bilateral optic neuritis, together with gait disturbance, intention tremor of the upper extremities, urinary retention, constipation, abnormal sensation in the distal part of the lower extremities, and moderate hemiplegia on the left side. Autoantibodies, including anti-aquaporin 4 (AQP4) and anti-myelin oligodendrocyte glycoprotein (MOG), were all negative. She showed multifocal spinal cord lesions on MRI and oligoclonal bands in the cerebrospinal fluid obtained by spinal tap, and so underwent steroid pulse therapy with methylprednisolone in the tentative diagnosis of multiple sclerosis, resulting in visual acuity recovery and alleviation of neurological symptoms. In the literature review, the combination of optic neuritis and hypophysitis, mostly with diabetes insipidus, was reported in 15 patients as case reports before the years of COVID-19 pandemic. The COVID-19 vaccination would trigger the onset of hypophysitis and optic neuritis in this patient.

Abstract
A 63-year-old woman, with 11-year history of breast cancer, showed bilateral lacrimal gland enlargement on magnetic resonance imaging. Gallium-67 scintigraphy, as the standard at that time in 2004, demonstrated abnormally high uptake only in bilateral lacrimal glands. The lacrimal glands were extirpated and the pathological diagnosis was mantle cell lymphoma (MCL). She underwent bilateral orbital radiation, based on no uptake of gallium-67 in other sites of the body. In a month, bone marrow biopsy revealed the infiltration with MCL, positive for cyclin D1. She showed hepatic lymphadenopathy and splenomegaly, and so received 2 cycles of alternating Hyper-CVAD therapy and high-dose methotrexate with cytarabine, combined with rituximab, in 2 months, leading to complete remission. She underwent autologous peripheral blood stem cell transplantation and was well until the age of 68 years when she showed a recurrent intratracheal submucosal lesion of lymphoma and underwent one course of reduced-dose CHOP combined with rituximab. Next year, the left rib resection revealed the metastasis of breast adenocarcinoma, leading to daily oral letrozole. Further 2 years later, computed tomographic scan demonstrated multiple submucosal nodular lesions in the trachea and bronchi, together with cervical and supraclavicular lymphadenopathy, and intratracheal lesion biopsy and bone marrow biopsy proved the involvement with MCL. She underwent 2 courses of bendamustine and rituximab, resulting in complete remission but died of metastatic breast cancer at the age of 74 years. Clinical features in 48 previous cases with ocular adnexal MCL in the literature were summarized in this study.

Abstract
The reduced use of antimicrobial drugs has been recommended worldwide, according to the global action for antimicrobial resistance published in 2015 by the World Health Organization. In this study, we retrospectively reviewed the incidence of surgical site infection in consecutive patients with cataract surgeries at a single hospital in the 6-year process when prophylactic systemic antibiotics were reduced in a step-by-step manner. The entire study period from 2016 to 2022 was divided into five stages, based on the use of systemic antibiotics. In stage 1 with 649 cataract surgeries, an intravenous drip infusion of cefazolin 1 g was given at surgery, followed by oral cefdinir 100 mg in the evening on surgery day and three times for two postoperative days. In stage 2 with 541 cataract surgeries, oral cefdinir 100 mg was given in the late morning before surgery, in the evening, and three times (300 mg in total) for two postoperative days. In stage 3 with 103 cataract surgeries, oral levofloxacin 500 mg was given in the late morning before surgery and once in the morning for two postoperative days. In stage 4 with 545 cataract surgeries, oral levofloxacin 500 mg was given only in the late morning before surgery. In stage 5 with 311 cataract surgeries, no systemic antibiotics were given. As common procedures in all stages, moxifloxacin eye drops were given four times daily as topical antibiotics in the 3 days before surgery and about 2 weeks after surgery. At surgery, the ocular surface was frequently irrigated with saline-diluted povidone iodine at 0.5% working concentration. No postoperative infection was recorded in any stage. This study showed neither harm nor risk in reduced use and, consequently, no use of prophylactic systemic antibiotics in cataract surgery as far as local precautionary measures were secured.

Abstract
We report a patient with sarcoidosis who developed diffuse large B-cell lymphoma. A 71-year-old woman with persistent cough was diagnosed pathologically with sarcoidosis by resection of the right upper lung lobe with a nodule after an unsuccessful attempt of transbronchial needle aspiration for mediastinal lymphadenopathy. She was referred for an eye examination and found to have spotty retinal degeneration on the lower fundi of both eyes, together with residual macular edema and vitreous opacity in the left eye. At 76 years, she underwent cataract surgery and vitrectomy to gain a visual acuity of 0.6 in the left eye. At 77 years, she developed a cough and fever, and showed leukopenia and thrombocytopenia. Computed tomography showed multiple small nodular lesions in both lungs, and bilateral hilar, mediastinal, and hepatic lymphadenopathy. Fluorodeoxyglucose positron emission tomography demonstrated high uptake in the liver, spleen, pancreatic head, and lymph nodes. Bone marrow biopsy was intact, but liver biopsy revealed anomalous large lymphoid cells in the sinusoids which were positive for CD20 and showed a high Ki-67 index, leading to the diagnosis of diffuse large B-cell lymphoma. Chemotherapy with 8 courses of THP-COP (cyclophosphamide, pirarubicin, vincristine, and prednisolone) with rituximab, followed by intrathecal injection of methotrexate, cytarabine, and dexamethasone, resulted in complete remission. She maintained complete remission for 10 years until 88 years old at present. The literature review found 30 patients, including this case, who developed lymphoma in the course of sarcoidosis. A novel pathological diagnosis is required in the setting of acute symptomatic changes and novel lesions on imaging in patients with sarcoidosis.

Photorefraction with Spot Vision Screener versus Visual Acuity Testing as Community-Based Preschool Vision Screening at the Age of 3.5 Years in Japan. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2022; 19:ijerph19148655. [PMID: 35886507 PMCID: PMC9321534 DOI: 10.3390/ijerph19148655] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 06/08/2022] [Revised: 07/12/2022] [Accepted: 07/14/2022] [Indexed: 12/04/2022]
Abstract
Nationwide in Japan, a community-based vision-screening program in 3.5-year-old children is conducted in three steps: questionnaires and home visual acuity testing as the primary screening; visual acuity testing by nurses and pediatricians’ inspection in community health centers as the secondary screening; and examinations by ophthalmologists as the tertiary screening. In this study, we introduced photorefraction with a Spot vision screener in addition to visual acuity testing to answer the clinical question of whether photorefraction could better detect eye diseases and potentially replace visual acuity testing. Photorefraction was performed on 813 consecutive 3.5-year-old children in a center. The children were sent to tertiary examinations, which were based on the Spot vision screener standard, in addition to the visual acuity testing standard: failure in either eye to pass 0.5 visual acuity in a center. A notice to visit ophthalmologists was issued for 95 children (11%), and documents with the diagnosis were sent back to the Heath Office for 76 children (80%). The rate of children with anisometropic or ametropic amblyopia or accommodative esotropia as treatment-requiring diseases was highest in cases of no pass at both standards (10/15 = 66%), and higher in cases of no pass only at the Spot vision screener standard (13/45 = 28%), compared with cases of no pass only at the visual acuity testing standard (6/33 = 18%, p = 0.0031). Photorefraction, in addition to visual acuity testing and inspection led to additional eye diseases detection at 3.5 years. Visual acuity testing at home would not be omitted in the introduction of photorefraction.

Abstract
IgG4-related disease is a recently established clinical entity. The disease might serve as the background for later development of systemic lymphoma. This study aims to confirm the diagnosis of IgG4-related disease by re-staining lacrimal gland lesions diagnosed previously with low-grade lymphoma in a patient who developed systemic diffuse large B-cell lymphoma (DLBCL) 18 years later. A 53-year-old man developed bilateral lacrimal gland swelling and right submandibular gland swelling and was diagnosed by excision as low-grade lymphoma. In follow-up, positron emission tomography showed high uptake in the median hyoid 11 years later but no malignancy was detected by laryngeal submucosal biopsy. He was well with no treatment until 18 years later when he had palatal swelling and was diagnosed with DLBCL by oral floor biopsy. He had systemic lymphadenopathy, infiltration in paranasal sinuses, hypopharynx, small intestine, kidney, and prostate. He underwent 8 courses of R-CHOP and 3 courses of high-dose methotrexate and achieved complete remission with no relapse for 1 year thereafter. Re-immunostaining of paraffin blocks of bilateral lacrimal gland lesions showed IgG and IgG4-positive lymphocytes and plasma cells among lymphoid follicles separated by fibrous bundles, with 10 or more IgG4-positive cells in high-power field. The IgG4/IgG-positive cell ratio was 100% and the number of κ chain-positive cells and λ chain-positive cells was the same. The bilateral lacrimal lesions were thus re-diagnosed as IgG4-related disease. In conclusion, systemic DLBCL occurred approximately 20 years after lacrimal gland IgG4-related disease. Literature review revealed 12 patients with IgG4-related disease, including the present patient, who later developed lymphoma in the other organs.

COVID-19 mRNA Vaccine-Associated Uveitis Leading to Diagnosis of Sarcoidosis: Case Report and Review of Literature. J Investig Med High Impact Case Rep 2022; 10:23247096221086450. [PMID: 35313760 PMCID: PMC8943455 DOI: 10.1177/23247096221086450] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/11/2022] [Revised: 02/14/2022] [Accepted: 02/20/2022] [Indexed: 12/02/2022] Open
Abstract
A 34-year-old Japanese person with male gender identity who had been taking intramuscular injection of methyltestosterone depot for 11 years after bilateral mastectomy noticed blurred vision 5 days after the second vaccination for COVID-19 (Tozinameran; Pfizer-BioNTech) in the interval of 3 weeks following the first vaccination. The patient was diagnosed as granulomatous iritis with mutton-fat keratic precipitates and small iris nodules at the pupillary margin in the right eye and began to have 0.1% betamethasone eye drops with good response. The patient, however, continued to have fever and malaise and showed a high level of serum soluble interleukin-2 receptor (sIL-2R) even 4 weeks after the second vaccination. Computed tomographic scan disclosed mediastinal and bilateral hilar small lymphadenopathy together with limited granular lesion in the right lung. Gallium-67 scintigraphy demonstrated high uptake not only in mediastinal and hilar lymph nodes but also in bilateral parotid glands. Right parotid gland biopsy revealed noncaseating granulomas and proved pathological diagnosis of sarcoidosis. The systemic symptoms were relieved by oral prednisolone 20 mg daily. Even though the causal relationship remains undetermined, this case is unique at the point that vaccine-associated uveitis led to the detection of pulmonary lesions and lymphadenopathy, resulting in clinical and pathological diagnosis of sarcoidosis. In literature review, 3 patients showed sarcoidosis-like diseases after COVID-19 vaccination: 2 patients were diagnosed clinically as Lofgren syndrome with acute onset of erythema nodosum and ankle swelling, with or without mediastinal and hilar lymphadenopathy, whereas 1 patient with mediastinal lymphadenopathy but no uveitis was diagnosed pathologically by biopsy as sarcoidosis.

Effect of NK-5962 on Gene Expression Profiling of Retina in a Rat Model of Retinitis Pigmentosa. Int J Mol Sci 2021; 22:ijms222413276. [PMID: 34948073 PMCID: PMC8703378 DOI: 10.3390/ijms222413276] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/25/2021] [Revised: 12/03/2021] [Accepted: 12/06/2021] [Indexed: 11/18/2022] Open
Abstract
Purpose: NK-5962 is a key component of photoelectric dye-coupled polyethylene film, designated Okayama University type-retinal prosthesis (OUReP™). Previously, we found that NK-5962 solution could reduce the number of apoptotic photoreceptors in the eyes of the Royal College of Surgeons (RCS) rats by intravitreal injection under a 12 h light/dark cycle. This study aimed to explore possible molecular mechanisms underlying the anti-apoptotic effect of NK-5962 in the retina of RCS rats. Methods: RCS rats received intravitreal injections of NK-5962 solution in the left eye at the age of 3 and 4 weeks, before the age of 5 weeks when the speed in the apoptotic degeneration of photoreceptors reaches its peak. The vehicle-treated right eyes served as controls. All rats were housed under a 12 h light/dark cycle, and the retinas were dissected out at the age of 5 weeks for RNA sequence (RNA-seq) analysis. For the functional annotation of differentially expressed genes (DEGs), the Metascape and DAVID databases were used. Results: In total, 55 up-regulated DEGs, and one down-regulated gene (LYVE1) were found to be common among samples treated with NK-5962. These DEGs were analyzed using Gene Ontology (GO) term enrichment, Kyoto Encyclopedia of Genes and Genomes (KEGG), and Reactome pathway analyses. We focused on the up-regulated DEGs that were enriched in extracellular matrix organization, extracellular exosome, and PI3K–Akt signaling pathways. These terms and pathways may relate to mechanisms to protect photoreceptor cells. Moreover, our analyses suggest that SERPINF1, which encodes pigment epithelium-derived factor (PEDF), is one of the key regulatory genes involved in the anti-apoptotic effect of NK-5962 in RCS rat retinas. Conclusions: Our findings suggest that photoelectric dye NK-5962 may delay apoptotic death of photoreceptor cells in RCS rats by up-regulating genes related to extracellular matrix organization, extracellular exosome, and PI3K–Akt signaling pathways. Overall, our RNA-seq and bioinformatics analyses provide insights in the transcriptome responses in the dystrophic RCS rat retinas that were induced by NK-5962 intravitreal injection and offer potential target genes for developing new therapeutic strategies for patients with retinitis pigmentosa.

Abstract
The present study describes proton beam therapy as a clinical option to achieve local control of giant conjunctival melanoma in an aged person, instead of orbital exenteration. An 80-year-old woman with one-year history of left-eye injection and hemorrhage experienced rapid growth of the ocular surface black mass. At the initial visit, a black, elastic hard, hemorrhage-prone, thickened mass in the size of 30x40 mm with a presumed wide stalk covered the total area of the lid fissure on the left side. Biopsy of the mass demonstrated anomalous melanin-containing cells in fibrin and hemorrhage, which were positive for cocktail-mix antibodies against tyrosinase, melanoma antigen recognized by T cells-1 and human melanoma black-45, indicative of malignant melanoma. One month after the initial visit, the patient underwent proton beam therapy at the total dose of 70.4 Gy (relative biological effectiveness) in 32 fractions (~10 min each) in one and a half months. One month after the end of proton beam therapy, 3.5 months from the initial visit, the patient was found by computed tomographic scan to have multiple metastatic lesions in bilateral lung fields. With the evidence of absent BRAF mutation, the patient underwent intravenous administration of pembrolizumab 77.2 mg every three weeks five times in total. Then, three months after proton beam therapy, ocular surface melanoma almost subsided and the clear cornea allowed visualization of the intraocular lens inside the eye. In three weeks, spontaneous corneal perforation was plugged with iris incarceration. The patient died suddenly of unknown cause 7.5 months from the initial visit. The local control of giant conjunctival melanoma was achieved by proton beam therapy, leading to patient's satisfaction and better quality of life. Proton beam therapy, followed by immune checkpoint inhibitors, would become the future standard of care for unresectable giant conjunctival melanoma.

464Basics of survival analysis: age is not appropriate as time scale in Cox regression model. Int J Epidemiol 2021.

Abstract
Abstract
Background
Many previous methodological studies suggested to use age as time scale in Cox regression model, and some statistical analyses directly applied this conclusion. In the present study, we explain why age is not a more appropriate time scale compared to the time-on-study time scale.
Methods
We address this argument based on five aspects: Cox regression model, conditional likelihood estimation, dataset of left-truncation or right-censoring, algorithms and software for Cox model, and inferring survival function. Furthermore, logical and algorithmic errors arise in the procedure of parameter inference with age time scale, and that certain evaluation indicators proposed by previous studies are inappropriate.
Results
The function of time scale is mainly a sampling method for maximum likelihood estimation to infer coefficient of Cox regression model, and the method defined by the age time scale is incorrect in logics and algorithms. Furthermore, age as time scale creates new problems, such as the omission of covariates, loss of information as a continuous variable, increase in dropout, and inability to obtain the survival function.
Conclusions
For the Cox regression model, the classic time-on-study time scale is more appropriate compared to age as time scale.
Key messages
It is an important discussion because using age as time scale was first proposed decades ago, meaning that lots of turnovers in researchers, newbies tend to accept the assumptions of their predecessors, but the suitability has never been rigorously verified.

Abstract
Juvenile idiopathic arthritis–associated uveitis is rare in the Japanese
population. In this article, we report a child whose macular edema was
controlled for years after cataract surgery with adalimumab, and reviewed 26
Japanese patients in the literature. In this case report, a 4-year-old boy
developed band keratopathy, posterior iris synechiae, and complicated cataract
in both eyes. Oral prednisolone prescribed at another hospital was discontinued
due to high intraocular pressure in both eyes as a steroid responder. At the age
of 5 years, he started oral methotrexate 8 mg weekly for recurrent bilateral
iridocyclitis and then underwent lensectomy with core vitrectomy in both eyes.
Planned intraocular lens implantation was cancelled at surgery because the
anterior vitreous had severe inflammatory opacity with diffuse retinal edema in
both eyes. Due to persistent macular edema in both eyes 5 months
postoperatively, at the age of 6 years, he began to use adalimumab injection 20
mg every 2 weeks. The macular structure depicted by optical coherence tomography
became normal in 2 months. At final visit at the age of 11 years, he had the
best-corrected visual acuity of 0.8 in the right eye and 0.4 in the left eye,
with adalimumab 40 mg every 2 weeks and methotrexate 8 mg weekly. In conclusion,
macular edema persistent despite oral methotrexate after cataract surgery could
be controlled for long term by adalimumab in a child with juvenile idiopathic
arthritis. In the Japanese literature, only 26 additional cases with juvenile
idiopathic arthritis–associated uveitis have been reported so far.

Abstract
This study reported 2 new patients and 16 historical cases with pathologically
proven intraocular infiltration with adult T-cell leukemia and lymphoma (ATLL)
to know the timing of intraocular infiltration in the disease course. The first
case was a 67-year-old woman who developed bilateral vitreous opacity about half
a year after the onset of acute type of ATLL that had been unresponsive to
chemotherapy. She underwent vitrectomy combined with cataract surgery in both
eyes. She had bilateral optic disc atrophy and localized retinal white
infiltrates in both eyes. Cytological examination of vitreous aspirates
demonstrated medium-sized cells with aberrant flower-like convoluted nuclei,
positive for CD3, and thus indicative of T-cells. The second case was a
38-year-old man who was diagnosed acute type of ATLL at the presentation of
acute kidney injury. About half a year after initial chemotherapy and allogeneic
hematopoietic stem cell transplantation, he developed aqueous hypopyon in the
right eye, concurrent with cutaneous and central nervous system relapse. Aqueous
tap disclosed class V abnormal cells. The aqueous “pseudohypopyon” resolved in
response to another round of chemotherapy with mogamulizumab. In review of 18
patients, intraocular infiltration with ATLL was diagnosed by vitrectomy in 9,
aqueous tap in 3, chorioretinal biopsy in 3, and autopsy in 3. The intraocular
infiltration developed concurrently with systemic diagnosis of ATLL in 5
patients, but developed later after chemotherapy in 13. In conclusion,
intraocular infiltration with ATLL appears rare, and pathological diagnosis by
vitrectomy and aqueous tap would help determine therapeutic plan in relapse
after chemotherapy.

Abstract
The OPERA experiment was designed to discover the vτ appearance in a vμ beam, due to neutrino oscillations. The detector, located in the underground Gran Sasso Laboratory, consisted of a nuclear photographic emulsion/lead target with a mass of about 1.25 kt, complemented by electronic detectors. It was exposed from 2008 to 2012 to the CNGS beam: an almost pure vμ beam with a baseline of 730 km, collecting a total of 1.8·1020 protons on target. The OPERA Collaboration eventually assessed the discovery of vμ→vτ oscillations with a statistical significance of 6.1 σ by observing ten vτ CC interaction candidates. These events have been published on the Open Data Portal at CERN. This paper provides a detailed description of the vτ data sample to make it usable by the whole community.

Abstract
The present study aimed to evaluate the effects of NK-4 on the apoptosis of photoreceptors in a rat model of retinitis pigmentosa and explore the mechanism underlying anti-apoptosis activity. The Royal College of Surgeons (RCS) rats received an intravitreous injection of NK-4 solution in the left eye and vehicle control in the right eye. Apoptosis was detected by TUNEL method in frozen sections of the eyes. The retinal tissues of the rats were dissected for RNA-seq analysis. Functional and pathway enrichment analyses of differentially expressed genes (DEGs) were performed by using Metascape and DAVID software. The expression levels of DEGs were confirmed by real-time quantitative PCR (RT-qPCR). The number of apoptotic cells decreased in the outer nuclear layer (ONL) and the thickness of the ONL was significantly thicker in the retina of NK-4-injected eyes, compared with control eyes. Five DEGs were identified by RNA-seq analysis, and Hmox1, Mt1, Atf5, Slc7a11, and Bdh2 were confirmed to be up-regulated by RT-qPCR. Functional and pathway enrichment analysis of the up-regulated genes showed that anti-apoptosis effects of NK-4 in the retina of RCS rats may be related to the pathways of metal ion homeostasis, negative regulation of neuron death, response to toxic substance, and pigment metabolic process. We found a potential mechanism of NK-4, providing a new viewpoint for the development of more therapeutic uses of NK-4 in the future.

Abstract
Purpose: To perform a systematic review on the association between alcohol consumption and risk of age-related macular degeneration (AMD) using a meta-analytical approach.Method: Systematic literature research was conducted according to the Preferred Reporting Items for Systematic Review and Meta-Analyses guidelines. Both categorical and dose-response meta-analysis was performed separately for early and late AMD. A fixed-effect model was used to calculate pooled effect estimates with 95% confidence interval (CI).Result: Seven studies were included in the analysis with 4,566 and 440 cases of early and late AMD, respectively. Compared to the nondrinkers or occasional drinkers, the pooled effect estimates for early AMD with moderate (1.19, 95% CI [1.03-1.37]) and heavy (1.24, [1.10-1.39]) alcohol consumption, but not light (0.95, [0.90-1.06]) alcohol consumption, were statistically significant. However, the pooled effect estimates for late AMD with light (1.03, [0.79-1.33]), moderate (1.13, [0.83-1.55]), and heavy (0.98, [0.63-1.53]) alcohol consumption were found to be insignificant. A linear dose-response relationship was established (P < .05) between alcohol consumption and risk of early AMD, and the pooled effect estimate for an increase in alcohol consumption of 10 g/day was 1.14 (1.08-1.21).Conclusion: Moderate and heavy alcohol consumption could increase the risk of early AMD, but not late AMD, with a linear dose-response relationship.

Abstract
Metastatic choroidal tumors derived from prostate cancer are rare. In this study,
we report a patient who manifested a choroidal tumor as the initial presenting
sign of prostate cancer and review 23 patients with choroidal metastasis of
prostate cancer in the literature to answer a clinical question how the
choroidal metastases would respond to hormonal therapy. A 73-year-old man
presented with a choroidal tumor in the right eye. He was in good health and had
no previous history except for current hemodialysis in 3 years due to chronic
renal failure as a sequel to glomerulonephritis. With the diagnosis of a
probable metastatic tumor, positron emission tomography was performed to
disclose high-uptake sites in multiple bones, lymph nodes, and the prostate,
together with multiple nodular lesions in bilateral lungs on computed tomography
(CT) scan. Serum prostate-specific antigen (PSA) was elevated to 541 ng/mL,
which supported prostate cancer as the primary site. He had degarelix injection,
and the choroidal tumor resolved rapidly and became flat degeneration in a
month. Prostate biopsy showed poorly differentiated adenocarcinoma, and he
underwent surgical castration. He had no medication until 3 years later when he
showed gradual increase of serum PSA up to 6.05 ng/mL and multiple bony
metastases on CT scan. Bicalutamide, switched to enzalutamide and then to
abiraterone, led to the undetectable level of serum PSA until the last visit
with no relapse of the choroidal metastasis, 6.8 years after the initial visit.
In the literature review of 24 patients with choroidal metastasis of prostate
cancer, including this patient, 8 patients presented a choroidal tumor as the
initial sign and the choroidal lesions mostly showed complete response to
hormonal therapy. Among 13 patients who were frequently in the course of
hormonal therapy, choroidal metastases showed complete or partial response to
external beam radiation to the eye in 11 patients and episcleral plaque
radiotherapy in 2 patients. In conclusion, metastatic choroidal tumors of
prostate cancer would show good response to hormonal therapy when the therapy
has not been initiated. Hormone-resistant choroidal metastases in the
therapeutic course of prostate cancer could be managed successfully by external
beam radiation to the eye.

Abstract
The diagnostic criteria for IgG4-related disease were previously published and serum IgG4 measurement has been reimbursed by national health insurance in Japan since 2012. Eight patients diagnosed with IgG4-related disease based on lacrimal gland masses were retrospectively reviewed. The 8 patients were 3 men and 5 women ranging in age from 52 to 77 (median, 63) years at the initial visit and their follow-up period ranged from 0.25 to 11 (median, 7) years. Bilateral and unilateral involvement were noted in 4 patients each; 2 on the right side and 2 on the left side in those with unilateral involvement. Serum IgG4 was high in 5 of 8 patients at the initial visit. Five patients with no systemic signs were followed without treatment, whereas oral steroids were administered and tapered in the other 3 patients who exhibited systemic signs. One patient with a history of radiation for MALT lymphoma in bilateral lacrimal glands developed IgG4-related disease in the left lacrimal gland 10 years later and was followed without treatment. Nine years later, her serum IgG4 level increased to 1500 mg/dL and paracardiac lesions, found on positron emission tomography, were confirmed to be MALT lymphoma by needle biopsy, leading to systemic chemotherapy. The other 7 patients had neither local recurrence nor additional systemic signs. Serum IgG4 monitoring may be useful to detect systemic complications in IgG4-related ophthalmic disease and markedly high serum IgG4 levels may indicate new lymphoma at other sites.

Objective.Retinal prostheses have been developed to restore vision in blind patients suffering from diseases like retinitis pigmentosa.Approach.A new type of retinal prosthesis called the Okayama University-type retinal prosthesis (OUReP) was developed by chemically coupling photoelectric dyes to a polyethylene film surface. The prosthesis works by passively generating an electric potential when stimulated by light. However, the neurophysiological mechanism of how OUReP stimulates the degenerated retina is unknown.Main results.Here, we explore how the OUReP affects retinal tissues using a finite element model to solve for the potential inside the tissue and an active Hodgkin-Huxley model based on rat vision to predict the corresponding retinal bipolar response.Significance.We show that the OUReP is likely capable of eliciting responses in retinal bipolar cells necessary to generate vision under most ambient conditions.

Abstract
PURPOSE To study the association between television-watching in the earlier years of life and subsequent parents' concerns about decreased visual acuity in their elementary school-aged child. STUDY DESIGN Population-based longitudinal cohort. METHODS Television-watching and its daily duration, as the main exposure, and parents' concerns for their child's decreased visual acuity during the school years, as the main outcome, were picked up from yearly questionnaires performed for the Longitudinal Survey of Newborns in the Twenty-First Century involving all babies born in Japan during either of two periods: between January 10 and 17, 2001 or between July 10 and 17, 2001 (N = 47,015). RESULTS Television-/video-watching as the main form of play of children at the ages of 1.5 years and 2.5 years was significantly associated with parents' concerns for their child's decreased visual acuity raised once or more in six surveys conducted between the ages of 7 and 12 years (odds ratio, 1.1 and 1.09; 95% CI 1.05-1.15 and 1.04-1.14, respectively). The association remained significant after adjustment for confounding variables, including child's sex, preterm birth, multiple birth, mother's age at delivery, mother's and father's education, and residential area. Longer daily duration of television-watching at 2.5 years was significantly associated with concerns for the child's decreased visual acuity between the ages of 7 and 12 years, but not at the ages of 3.5, 4.5, and 5.5 years. The association remained significant in a sensitivity analysis of 28,820 children who participated in all six surveys. CONCLUSIONS Longer daily exposure to television in children in the earlier years of life was associated with parents' subsequent concerns about decreased visual acuity in their elementary school-aged child.

Abstract
Retinal prostheses have been developed to restore vision in blind patients suffering from such diseases as retinitis pigmentosa. In our previous studies, we developed a retinal prosthesis called dye-coupled film by chemical coupling of photoelectric dyes, which absorb light and then generate electrical potential, with a polyethylene film surface. The dye-coupled film is nontoxic, and we recovered the vision of a monkey with macular degeneration. The amount of dye on the dye-coupled film, however, decreased to one-third after five months in the monkey's eye. The photoelectric dye consists of a cation with photoresponsivity and a bromide ion (Br-). Therefore, an anion-exchange reaction could be applied to the dye-coupled film to improve its durability. In this study, the anion-exchange reaction was conducted using bis(trifluoromethanesulfonyl)imide ion (TFSI-), which has lower nucleophilicity than Br-. First, the long-term durability was examined without using animal subjects and in a short period. Subsequently, an elemental analysis was performed to confirm the exchange between Br-and TFSI-, and chemical properties, such as photoresponsivity and durability, before and after the anion exchange, were evaluated. It was quantitatively confirmed that the long-term durability of dye-coupled films can be evaluated in an in vitro environment and in a short period of one-thirtieth by utilizing a saline solution at 60°C, compared with an in vivo environment. In addition, the durability of the dye-coupled film with TFSI-was improved to 270%-320% compared with that of the dye-coupled film with Br-.

Abstract
Background. Primary malignant melanoma of the lacrimal sac is
rare. A patient with lacrimal sac melanoma was presented, and 14 Japanese
patients with lacrimal sac melanoma in the literature were reviewed.
Case Presentation. A 78-year-old Japanese man was presented
with painless swelling of the lacrimal sac on the left side. Dacryocystectomy
revealed diffuse infiltration with large epithelioid cells, sometimes with
pigments, which were positive for cocktail mix of antibodies to tyrosinase,
melan A (MART-1), and HMB45, leading to pathological diagnosis of melanoma. One
month later, positron emission tomography (PET) revealed 2 high-uptake sites
(SUVmax = 10.29 and 15.38) at the levels of medial canthus and
nasolacrimal duct, but no abnormal uptake in the other site of the body. The
lesion had the BRAF V600E mutation. He began to take daily oral dabrafenib (BRAF
inhibitor) and trametinib (MEK inhibitor), leading to no abnormal uptake on PET
in half a year. He had stable disease in good physical status with small and
weak uptake sites of lymph nodes on PET 1 year later. Results.
In the review of 15 Japanese patients, including this patient, local recurrence
was noted in 4 patients, regional lymph node metastasis only in 3, distant
metastasis in 6, and no metastasis in 6. Five patients died within 2 years and
the others were alive in short follow-up periods. Conclusions.
Chemotherapy was the standard for local recurrence or metastasis. Emerging
molecular target drugs, as shown in the present patient, would change the
strategy for management of lacrimal sac melanoma.

Abstract
Primary intraocular lymphomas frequently develop into central nervous system lymphomas and vice versa. This study reviewed 22 consecutive patients with primary intraocular lymphoma diagnosed by immunostaining of vitrectomy cell blocks, and examined whether they developed central nervous system lymphoma. Seventeen patients developed central nervous system lymphoma: 3 patients developed intraocular and central nervous system lymphoma simultaneously, 9 patients developed central nervous system lymphoma 1 month to 5 years (median, 3 months) after intraocular lymphoma, and 5 patients developed central nervous system lymphoma preceding the diagnosis of intraocular lymphoma by 3 months to 9 years and 8 months (median, 1.5 years). In contrast, 5 patients did not develop central nervous system lymphoma: 2 patients did not develop local recurrence or central nervous system lymphoma in the follow-up period of 5 years and 11 years, respectively, after vitrectomy alone without additional local or systemic treatment. The remaining 3 patients with intraocular lymphoma had insufficient follow-up periods to determine the prognosis. The results of CD5 immunostaining of vitrectomy specimens were found in pathology reports of 8 patients: 3 patients with CD5-positive large cells and 4 patients with CD5-negative large cells developed central nervous system lymphoma. In summary, only a small number of patients did not develop central nervous system lymphoma based on long-term follow-up after vitrectomy alone. CD5 was not a marker of central nervous system involvement in this study population.

Abstract
Purpose: Idiopathic orbital myositis, a rare disease of unknown cause, presents a diagnostic puzzle because the diagnosis is based on the exclusion of other diseases. This study aims at elucidating its long-term outcome to answer a clinical question whether idiopathic orbital myositis would be a distinct clinical entity. Methods: Retrospective review was made on 7 consecutive patients (6 men and 1 woman) with the age at the initial visit ranging from 33 to 69 years (mean, 45.8 years) who were diagnosed with idiopathic orbital myositis and followed for 5 years or more (mean, 9.2 years) at a referral-based hospital. Results: Chief complaint at the initial visit was diplopia in 4 patients, blurred vision in 2 patients, and proptosis in 1 patient. On magnetic resonance imaging, 4 patients showed enlargement of a single extraocular muscle on unilateral side while 3 patients showed enlargement of multiple extraocular muscles on unilateral side or bilateral sides. No patient developed systemic diseases or other orbital lesions in the long-term follow-up. All patients at the last visit were free from symptoms, including diplopia, after tapering of prednisolone at the initial dose of 20 to 60 mg daily. Conclusion: Idiopathic orbital myositis had a favorable long-term outcome with corticosteroid administration and appears to be a distinct clinical entity without systemic involvement.

Abstract
Background Vision plays a key role in some behavior tests for rats. Okayama University-type retinal prosthesis (OUReP) is a photoelectric dye-coupled polyethylene film which generates electric potential in response to light and stimulates nearby neurons. This study aims to assess vision in retinal dystrophic (RCS) rats, in comparison with normal rats, by selected behavior tests. We also examined whether the tests could detect vision changes in RCS rats with dye-coupled film implantation. Methods Data sets were 5 normal rats, 4 untreated RCS rats, 7 RCS rats with dye-coupled films implanted at the age of 7 weeks after excluding unsuccessful implantation at autopsy. Behavior tests chosen were landing foot splay and visual forelimb-placing response in the menu of functional observational battery, operant-conditioning lever-press response and light/dark box test. Results Normal visual placing response was significantly less frequent in untreated RCS rats at the age of 9 and 11 weeks, compared with normal rats (P = 0.0027, chi-square test) while normal response was significantly more frequent at the age of 9 weeks in RCS rats with dye-coupled film implantation, compared with untreated RCS rats (P = 0.0221). In operant-conditioning lever-press test, the correct response rate was significantly lower in untreated RCS rats than in normal rats at the age of 9 weeks (P < 0.05, Tukey-Kramer test) while the rate was not significantly different between normal rats and RCS rats with dye-coupled film implantation. In light/dark box test, the time to enter dark box was significantly shorter in normal rats, compared with untreated RCS rats or RCS rats with dye-coupled film implantation (P < 0.05, Tukey-Kramer test). Conclusions Behavior tests of functional observational battery, operant-conditioning lever-press response and light/dark box test discriminated vision between normal rats and RCS rats. The visual placing response and operant-conditioning lever-press test might have sensitivity to detect vision recovery in RCS rats with OUReP implantation.

Abstract
Background Three-rods test is required as depth perception vision test to obtain motor vehicle license to drive taxies, buses, and trucks in Japan. Functional visual acuity is measured automatically by successive visual target presentation in a fixed period of time. This study examined three-rods test from the viewpoint of reproducibility, eye deviation, and functional visual acuity to assess the feasibility for drivers' license vision test. Methods At three-rods test, a central rod was moved at the speed of 50 mm/sec forward and backward automatically against two fixed rods on both sides inside an illuminated box. An examinee at the distance of 2.5 m observed the rods inside the box from a small window and pushed a button to stop the central rod in alignment with the fixed rods. Erred distance of the central rod from the fixed rods as a mean of 4 measurements was used. At functional visual acuity test, an examinee moved a joystick to the same direction as Landolt-C opening as a visual target which was sequentially presented every 2 seconds for 30 times in 1 minute. Results The mean erred distance of three-rods test was reproducible between two tests done on separate occasions (n = 44, ρ = 0.679, P < 0.0001, Spearman rank correlation). Exophoria induced by wearing 4-prism-diopter base-out prism did not significantly influence the mean erred distance while vertical diplopia induced by wearing 4-prism-diopter base-up prism disrupted the measurement (n = 9). The mean erred distance of three-rods test was better correlated with functional visual acuity tested with both eyes open than with conventional visual acuity with both eyes open (n = 17, ρ = 0.2 versus ρ = 0.179). Conclusion In the context of the small sample size in the present study, the three-rods test was reproducible, and testable in the presence of phoria, but not testable in diplopia, indicating the feasibility as a depth perception vision test.
