Paradoxical exacerbation of sclerouveitis following Rituximab infusion.

To report on an unexpected side effect of Rituximab (RTX), a B-cell targeting monoclonal agent, in a patient with severe sclerouveitis, leading to severe visual loss. Observational case report. A 61-year-old female was treated with RTX for a severe sclerouveitis occurring with granulomatosis with polyangiitis. Initially it responded partly to high dose of oral corticosteroids, however, her sclerouveitis recurred after two months during tapering below 20mg daily. The days following the RTX infusions, aggravation of the intraocular inflammation was seen, endangering visual acuity. No evidence for an infection or other cause were found. High doses of oral corticosteroids were started within one week, where after the ocular inflammation resolved. For persisting hypotony and chorioretinal detachment a combined pars plana vitrectomy with phacoemulsification and silicone oil tamponade was performed. The retina remained attached under oil tamponade with partial improvement of the BCVA to finger counting. Ophthalmologist should be aware of the possibility of this paradoxical local reaction to RTX infusion, particularly in bilateral and/or severe cases, which carry a risk of a poor outcome.

Leber’s hereditary optic neuropathy: clinical and genetic analysis of Bulgarian patients

Leber’s hereditary optic neuropathy (LHON) is a rare maternally inherited disease caused by mutations in mitochondrial DNA (mtDNA) genes encoding subunits of complex I in the mitochondrial respiratory chain. The most common mutations causing LHON are G11778A, G3460A and T14484C, but there are also several less common mutations. LHON presents as acute or subacute bilateral visual loss, usually affecting young males. The aim of this study was to assess the clinical symptomatology and genetic analysis of Bulgarian patients with LHON. Twenty-two patients were diagnosed with LHON based on clinical evaluation and genetic examination (17 males and 5 females); 12 of them were previously reported, while 8 males and 2 females are newly diagnosed. A full neuroophthalmologic and genetic examination was performed. Eight patients had a family history of LHON, while 14 were isolated cases. The age at onset ranged from 3 to 43 years, and visual acuity ranged from counting fingers to 0.9. Genetic testing revealed various mutations, including a rare mutation G3635A in MT-ND1 in five affected members of one pedigree and digenic inheritance of G11778A and T14484C in three individuals from a different family. A variant m.15988A > G in the mitochondrial gene MT-TP with a high level of heteroplasmy was found in one patient. In addition to the most common mutations causing LHON, our patients also had rare mutations. These results suggest that genetic analysis of the entire mtDNA sequence is recommended in cases with strong clinical suspicion of LHON, since new rare mtDNA pathogenic variants are being identified.

Progress in central retinal artery occlusion: a narrative review.

Central retinal artery occlusion (CRAO) is a catastrophic ophthalmic emergency that severely impairs a patient's visual function, often reducing visual acuity to counting fingers or worse. Progress in CRAO research has provided new information regarding its epidemiological characteristics and led to useful assessments through various ophthalmic examinations. Additional insights about CRAO have been gained through studies of its pathophysiological mechanisms, improving intervention timing and enhancing patient prognosis. Treatment for CRAO has evolved, particularly with assistance from surgical instruments and surgical robots. Although surgical treatment is now possible, this option is not widely recognized by ophthalmologists. Conservative therapies have limited benefits compared with the natural course of disease. Recently, pars plana vitrectomy plus endovascular surgery has received considerable interest among ophthalmologists because of its potential efficacy in the treatment of CRAO. Considering the inconsistencies in rationale and efficacy of CRAO treatment modalities, it is important to distinguish between treatment effects and the natural courses of various CRAO subclasses. This narrative review explores progress in CRAO epidemiology, pathophysiology, ophthalmic examination, and treatment.

Chronic hypotony and uveitis managed with pars plana vitrectomy, silicone oil tamponade, and permanent keratoprosthesis.

We report a case of silicone oil placement after Boston Type 1 keratoprosthesis implantation for improvement and maintenance of intraocular pressure in a patient with chronic hypotony secondary to chronic uveitis. Observational case report. A 54-year-old female with a history of bilateral chronic panuveitis and subsequent hypotony presented with progressive corneal decompensation and band keratopathy in her better-seeing left eye. Her CDVA in her left eye declined from count fingers at 3' to hand motion. In an effort to clear the visual axis and stabilize intraocular pressure, implantation of a Boston Type 1 Keratoprosthesis combined with pars plana vitrectomy and silicone oil injection was performed. Post operatively, the intraocular pressure improved to the mid-teens and vision improved to count fingers at 4'with a follow-up of 2 years. Pars plana vitrectomy and injection of silicone oil after placement of a Boston Type 1 keratoprosthesis can successfully improve and maintain intraocular pressure in eyes affected by chronic uveitis with ciliary body atrophy and chronic hypotony. This strategy effectively reverses such problems as hypotony maculopathy, disk swelling, scleral infolding, and corneal failure.

Cultural similarities and specificities of finger counting and montring: Evidence from Amazon Tsimane' people

Numerical cognition might be embodied, that is, grounded in bodily actions. This claim is supported by the observation that, potentially due to our shared biology, finger counting is prevalent among a variety of cultures. Differences in finger counting are apparent even within Western cultures. Relatively few indigenous cultures have been systematically analyzed in terms of traditional finger counting and montring (i.e., communicating numbers with fingers) routines. Even fewer studies used the same protocols across cultures, allowing for a systematic comparison of indigenous and Western finger counting routines. We analyze the finger counting and montring routines of Tsimane' (N = 121), an indigenous people living in the Bolivian Amazon rainforest, depending on handedness, education level, and exposure to mainstream, industrialized Bolivian culture. Tsimane' routines are compared with those of German and British participants. Tsimane' reveal a greater variation in finger counting and montring routines, which seems to be modified by their education level. We outline a framework on how different factors such as handedness and reading direction might affect cross-cultural and within-cultural variation in finger counting.

Case Report: Simultaneous penetrating keratoplasty with autologous simple limbal epithelial transplantation as an alternative to keratoprosthesis

Introduction and importance: This case report highlights the multidisciplinary approach required to achieve successful anatomical and functional outcomes, in an eye with total limbal stem cell deficiency (LSCD) associated with underlying corneal scarring and thinning. Presentation of case: A 59-year-old gentleman had poor visual recovery in the right eye (RE) following accidental carbide blast, 1-year before presenting to us. The visual acuity was counting fingers and clinical examination revealed cicatricial entropion involving the upper eyelid, total LSCD, corneal scarring with a central descemetocele and cataract in the RE. Prior to ocular surface reconstruction, entropion correction was performed. Three months later, penetrating keratoplasty combined with cataract surgery and intraocular lens implantation (penetrating keratoplasty (PK) triple), with autologous simple limbal epithelial transplantation (SLET) was performed. The visual acuity was 20/100, 18 months after the surgery, with a clear well-epithelized corneal graft and stable ocular surface. Discussion: LSCD is caused by a decrease in the population and /or function of the limbal epithelial stem cells. Limbal stem cell transplantation (LSCT) is warranted in eyes with total LSCD. In eyes with coexisting corneal scarring, LSCT alone may be inadequate to restore the vision. These eyes require simultaneous or sequential lamellar or full-thickness corneal transplantation for visual rehabilitation. Though, the existing literature favors a sequential approach, where LSCT is performed first followed by corneal transplantation, under certain circumstances such as a thin underlying cornea like in our case, corneal transplantation may have to be combined with LSCT to achieve optimal outcomes. Conclusion: Combining autologous SLET with PK can be performed for visual rehabilitation in eyes with unilateral total LSCD and underlying corneal thinning. Corneal and limbal graft survival is prolonged if existing adnexal comorbidities are addressed before any surgical intervention is planned and adequate time interval is allowed for the surface inflammation to subside.

Grease-gun injury of the orbit: two cases report and literature review

BackgroundThe grease-guns injury is an uncommon injury to the orbit. We present the twelfth and thirteenth cases of grease-gun injury to the orbit to be reported in the English language literature since 1964. Here we discus and review the presentation, investigation, and treatment of this unusual trauma.Case presentationCase 1 was a 29-year-old man who presented 1 day after a grease-gun injury of the left orbit with severe pain, marked periorbital swelling, and proptosis. Computed tomography (CT) revealed penetration of grease into his left orbit. Following surgical removal, proptosis decreased. The limitation of extraocular movement and loss of visual acuity to finger count was discovered after the initial surgery. Motility gradually returned. Visual acuity recovered after phacoemulsification, capsular tension ring and intraocular lens implantation for traumatic cataract and subluxation. Case 2 was a 6-year-old boy who was referred 2 months after a grease-gun injury for worsening swelling with sinus, necrosis and slight ptosis of the upper left eyelids. This is a case of orbital chronic inflammation from grease-gun injuries masquerading as orbital cellulitis. The imaging findings of CT and magnetic resonance imaging (MRI) are not typical. Surgical exploration and debridement was inevitable and actually relieved the symptoms.ConclusionsGrease-gun injuries can damage the orbit in different degrees. Careful history inquiry and taking is important to establish the diagnosis. Imaging examinations using CT or MRI are helpful to determine depth of trauma and foreign bodies in the orbit at diagnosis. We suggest that surgical exploration and debridement is a key step in the management.

Management of 360° Peripheral Ulcerative Keratitis with Cataract in a One-Eyed: A Challenging Scenario

Abstract The purpose of this study is to discuss the management of 360° peripheral ulcerative keratitis with cataract in a patient with only one functioning eye. Peripheral ulcerative keratitis (PUK) is a type of crescent-shaped inflammatory damage that occurs in the limbal region of the cornea. PUK is always combined with an epithelial defect and the destruction of the peripheral corneal stroma. This is a case of a 78-year-old male who presented to us with complaints of redness in his right eye for the last year, with similar recurrent episodes on and off for the last 3 weeks. Examination revealed his right eye anterior segment having 360° peripheral ulcerative keratitis with dense brown hard cataract, and the uncorrected visual acuity was finger counting at 3 metres. At this point of the first examination, the eye was inflamed, so we decided to treat this patient in a phased manner. Phase-1 included a planned 360° amniotic membrane grafting when the eye is rendered quiet, followed by cataract extraction for the patient’s rehabilitation. This case demonstrates the approach we should consider in such cases, with a good result of accomplishing both phases and achieving a best-corrected visual acuity of 6/12 with a pinhole of 6/9.

Ocular involvement—An unusual initial presentation of chronic myeloid leukemia: A case report

ABSTRACT Chronic myeloid leukemia (CML) patients frequently exhibit systemic symptoms such as fatigue, abdominal discomfort, weight loss, and fever but rarely can have atypical initial presentation in the form of ophthalmic manifestations, which can precede the diagnosis of the primary malignancy. We describe a case of a 29-year-old male who presented in our ophthalmology out-patient department (OPD) with complaints of painless, diminution of vision, which was sudden in onset in right eye (RE) and loss of vision in left eye (LE) for four and seven days, respectively. There had been a history of loss of weight and appetite for the past 2 months. The visual acuity (VA) recorded was finger counting two meters in RE and perception of light in LE with an inaccurate projection of rays in both eyes (BE). The anterior segment evaluation of both eyes (BE) was normal. Fundus revealed multiple elevated yellow subretinal lesions with exudative detachment in the RE and no view in the LE. Ultrasound-Brightness (USG B) scan in the LE revealed multiple hyperreflective echoes likely vitreous hemorrhage. Optical coherence tomography (OCT) showed subretinal hyperreflectivity with surrounding edema in RE suggestive of leukemic infiltrates. On further systemic investigations, chronic myeloid leukemia-chronic phase (CML-CP) was detected; hence, the diagnosis of RE exudative retinal detachment (RD) and LE vitreous hemorrhage with CML-CP was made. Ophthalmic involvement is more often seen in acute than chronic leukemia, which makes the diagnosis challenging. We describe a unique case of a young patient with CML-CP who initially presented with ocular involvement preceding systemic diagnosis. This case report illustrates the importance of a primary care physician or an ophthalmologist in the early diagnosis and prompt management of hematological malignancy, as ophthalmic manifestations may be a rare initial presenting feature in CML-CP. These conditions require urgent referral to a hematologist by a primary care physician in the view of early commencement of therapy.

Auro-Keratoprosthesis for Visual Rehabilitation in Ocular Graft Versus Host Disease

Abstract A 36-year-old male presented with right eye graft melt post-penetrating keratoplasty (PK) for Aspergillus infection. The patient had a history of acute lymphocytic leukemia and had undergone a bone marrow transplant. He developed ocular graft versus host disease (GVHD) in both eyes and tissue adhesive application had to be performed for bilateral corneal melt. The right eye developed fungal keratitis, necessitating therapeutic keratoplasty. At presentation, the visual acuity was perception of light with an accurate projection of rays in the right eye and finger counting at 1 m in the left eye. An anterior chamber tap showed no organism on culture. Considering the non-ambulatory state of the patient and the need for early visual rehabilitation due to deteriorating mental well-being, a keratoprosthesis (KPro) surgery with amniotic membrane grafting was performed in the right eye. By post-operative day 20, the patient achieved a best-corrected visual acuity of 20/20. A PK was later performed in the other eye. It is conventionally believed that KPro is the last resort for bilateral corneal blindness and is commonly performed after multiple PK grafts have failed. However, this case highlights another indication of KPro in ocular GVHD; the rehabilitation of vision when PK will not work. In addition, this case illustrates the difference in the long-term outcomes between the two eyes, one that underwent early KPro surgery and the other that underwent early PK in ocular GVHD.

Cosmetic and visual outcomes following high-voltage severe electric facial and ocular burns: A case report

A 19-year-old male presented with accidental high-voltage electric burns following contact with a transformer while catching ball and developed right eye count finger vision and no perception of light in left eye. On examination, there were full thickness burns on upper half of left side of face, lids, and left leg involving 3rd, 4th, and 5th toes. Three surgeries were performed by the plastic surgeon for overall aesthetic look. The right eye regained vision following cataract surgery, but there was cosmetic and functional loss of left eye. This case report highlights that high-voltage electric burns of face and eye require proper surgical management and final visual outcome depends on amount of damage.15

Delayed onset Cutibacterium (formerly Propionibecterium) acnes endophthalmitis triggered by intravitreal steroid injection.

We report a case of delayed onset Cutibacterium acnes (C. acnes, formerly Propionibacterium acnes or P. acnes) endophthalmitis with onset triggered by intravitreal steroid (triamcinolone acetonide; TA) injection in a pseudophakic patient, 7 years after cataract surgery.Methods/Patients: A 67 years old, male presented with gradual worsening of vision, eye redness and photosensitivity that started a month after intravitreal TA injection (Triescience, 4mg/0.1mL, Alcon Labs, Fort Worth, TX) for cystoid macular edema secondary to branch retinal vein occlusion in the right eye. Patient had undergone cataract surgery with intraocular lens (IOL) in that eye 7 years prior. Exam showed visual acuity of counting fingers at 3 feet, conjunctival injection, with 2+ anterior chamber cell and 2+ vitreous haze. Uveitis work up including Angiotensin converting enzyme (ACE), Quantiferon Gold, and syphilis IgG screen was negative. Diagnostic pars plana vitrectomy (PPV) with intravitreal injection of antibiotics was performed and vitreous sample was sent for detailed laboratory analysis. Vitreous fluid analysis was positive for C. acnes and negative for viral, fungal and malignant cells. Although the patient received intravitreal antibiotics injection twice, the intraocular infection and inflammation persisted which eventually required an IOL and capsular bag removal, followed by insertion of a secondary IOL later. Delayed onset C. acnes endophthalmitis may be triggered by an intravitreal steroid injection in pseudophakic patients.

Electrophysiological and Visual Parameter Changes in Retinitis Pigmentosa Patients undergoing Autologous Platelet-Rich Plasma Therapy: A Randomized Control Trial.

To assess the efficacy of autologous platelet-rich plasma (PRP) injections in suprachoroidal space and subtenon space in cases of retinitis pigmentosa, which is a genetic disease, leading to gradual loss of vision. Till date, no treatment is available. Seventy-eight eyes of 39 patients of retinitis pigmentosa having visual acuity ranging from reading of Early Treatment Diabetic Retinopathy Study (ETDRS) chart from 1 m onward to patients who were not able to read the ETDRS chart but whose visual acuity ranged from finger count close to face to <1 m were included in the study. The left and right eyes of each patient were randomized as the intervention eye and control eye. 0.2 mL of autologous PRP was injected in suprachoroidal space and 0.5 mL of PRP was injected in subtenon space of the intervention eye taking aseptic precautions. Injections were repeated at 15-day intervals up to 3 injections. Majority of patients were in the age group of 18-30 years (20 cases) followed by 31-45 years (13 cases) and more than 45 years (6 cases). Intervention eyes showed a statistically significant improvement in visual acuity and multifocal electroretinography (mfERG). Improvement was noted in amplitude density latency and in ring ratio of mfERG. There was a significant improvement in best-corrected visual acuity (BCVA). However, no improvement in mfERG or BCVA was observed in the control group. Gene therapy may be the ultimate cure for retinitis pigmentosa, but it is unaffordable for many patients due to its high cost. PRP may be recognized as a modality to improve vision and stop further deterioration, especially in cases where functional vision is preserved. Negligible treatment costs and affordability will give power to economically disadvantaged patients.

Age no bar! Marsupialize frontal sinus mucopyocele to save the vision: A case report

Title: Age No Bar! Marsupialize Frontal Sinus Mucopyocele To Save The Vision: A Case Report. Introduction: Mucopyocele of the paranasal sinus is an accumulation of mucoid secretion covered by desquamated sinus epithelium with pus in the sinus with distension of its walls. It is an expansile, destructive lesion and can cause bone erosion along with the displacement of surrounding structures. Case Presentation: A 83 year old female patient came to the ENT Out Patient Department with chief complaints of right eye diminished vision, proptosis and swelling over the right side forehead since one year which resulted in obvious cosmetic deformity. On examination of face, there was a boggy swelling approximately 5 * 5 cm over right side forehead extending laterally to the lateral orbital wall with proptosis. Patient’s preoperative vision was 2.5 meters finger counting for the right eye and normal for the left. Non Contrast Computed Tomography of the Nose and Paranasal Sinuses revealed right sided frontal sinus mucocele extending to the right orbit. Magnetic Resonance Imaging of brain with orbit was done to confirm the diagnosis. Transnasal Endoscopic marsupialization of the mucocele was done under General Anaesthesia. There was a drastic improvement in right eye vision immediately from finger counting 2.5 meters to 6/12 with complete reduction of the boggy swelling and proptosis. Conclusion: We should always attempt endoscopic marsupialization of frontal sinus mucocele which is compromising vision irrespective of age to give back the patient his/her vision, confidence and happiness.

Collapsin response mediator protein 5-associated optic neuropathy: clinical characteristics, radiologic clues, and outcomes.

Collapsin response mediator protein 5-associated optic neuropathy (CRMP5-ON) is a rare entity of autoimmune optic neuropathy. This study aimed to review the neuro-ophthalmic findings and outcomes in a series of patients with CRMP5-ON to further characterize its clinical phenotype, radiologic clues, and outcomes. This was a retrospective case series and a single-center medical chart review of all patients with CRPM5-seropositive ON at the Department of Neurology, Beijing Tongren Hospital, from December 1, 2020, to March 31, 2023. The main outcome measures were neuro-ophthalmic manifestations, radiologic characteristics, and clinical outcomes of CRMP5-ON; coexisting neural autoantibody, paraneoplastic associations, and the impact of immunosuppressant therapy. Five patients were identified. Four (80%) were female, and the average age at onset was 59.4 years (range 53-69 years), with an average follow-up of 15.3 months (range 1.4-28.7 months). The average best-corrected visual acuity (BCVA) at nadir was 20/120 (range 20/20 to count fingers). Seven of ten affected eyes (70%) showed diffuse defects of the central field. Painless bilateral involvement and optic disk edema occurred in 100% of patients, combined with vitritis, uveitis, or retinitis in four (80%). Four patients (80%) had MRI abnormalities along the optic nerve (one patient with optic nerve enhancement and three patients had optic nerve sheath enhancement or peribulbar fat enhancement). Three patients (60%) had optic neuropathy with other neurologic symptoms. Four patients (80%) had confirmed cancer (two were small-cell lung carcinoma, one was papillary thyroid carcinoma and another was thymoma and invasive pulmonary adenocarcinoma). All cancers were identified after the presentation of the optic neuropathy. The intervention included IVIG, IVMP, surgery and chemotherapy. The average BCVA at the last follow-up was 20/50 (range 20/20 to count fingers). Three patients had surgery during the initial hospitalization, and were stable during the follow-up. Among two patients who received IVMP, both had improvement after treatment, although one patient had worsening non-ocular neurologic symptoms during the steroid taper. CRMP5-ON presented with optic disc edema, often bilateral involved and combined with vitreitis, retinitis, or uveitis. CRMP5-ON can present with MRI optic nerve or perineural optic nerve enhancement, especially in the optic nerve sheath. CRMP5-ON is closely related to paraneoplastic neurologic syndrome. Cancer screening and intervention are crucial to prognosis.

Clinical and Epidemiological Aspects of Eye Trauma at the Ouelessebougou Reference Health Center in the Koulikoro Health District in Mali

Introduction: Ocular trauma leads to isolated or associated lesions.These lesions are the cause of blindness worldwide. The frequency and nature of these traumas are diverse and varied. The aim of this study was to describe the clinical and epidemiological aspects of these ocular traumas at the reference health center of Ouelessebougou in Mali. Patients and Method: It was abouta retrospective cross-sectional study, carried out at the reference center of Ouelessebougou. It included all patients with ocular trauma received and followed up between July 1 and December 31, 2018. Results: The frequency of ocular trauma was 3.30%. It occurred in young subjects aged 5 to 14 years (26.47%); predominated the male subject with 52.94%. The consultation time was in 41.18% of cases greater than or equal to 72 hours. Domestic accidents were the main circumstances of occurrence with 55.8% of cases. The involvement was unilateral in 85.3% and bilateral in 14.7%. Visual acuity was positive Light Perception (PL+) at finger count (CLD) 3 meters in 44.12%. Contusion was the main type of trauma with (67.65%) followed by wounds with 20.59% of cases. Corneal opacities represented the main sequelae with 3 cases out of 34 or 8.82% of cases. Discussion: Ocular injuries most often occur in young, male subjects. The lesions are multiple and varied and can be a source of disabling sequelae. Conclusion: Eye injuries are a common condition, emphasis should be placed on prevention through mass awareness.

Purtscher-like retinopathy in a 19-year-old with maturity-onset diabetes of the young: a case report

BackgroundWe report the first case of Purtscher-like retinopathy in a patient with 17q12 deletion-associated maturity-onset diabetes of the young.Case presentationA 19-year-old diabetic Hispanic male with history of cataracts and toe amputations presented with sudden onset of painless bilateral vision loss for 1 week with no associated trauma. Visual acuity was counting fingers at six feet in both eyes. Dilated retinal examination revealed bilateral peripapillary cotton wool spots and intraretinal hemorrhages, and significant subretinal and intraretinal fluid on optical coherence tomography. Fluorescein angiography revealed arteriolar staining and leakage around the disc with areas of capillary nonperfusion, supporting the diagnosis of Purtscher-like retinopathy. Systemic workup revealed multiple diabetic complications including chronic osteomyelitis of multiple toes, nonhealing diabetic foot ulcers, neurogenic bladder and bowel, and bilateral lower-extremity muscular neuropathies. Genetic evaluation revealed a 17q12 deletion, which is associated with maturity-onset diabetes of the young 5. On follow-up examination, he received a single intravitreal antivascular endothelial growth factor injection in the left eye (off label) for persistent macular edema. Although his retinal edema improved, his visual acuity remained poor.ConclusionsThe presentation of our patient’s multiple diabetic complications along visual symptoms suggests Purtscher-like retinopathy can be a sequela of uncontrolled diabetes. Purtscher-like retinopathy is a rare but possible consideration in diabetic patients who present with acute-onset vision loss.

Counting Finger and Wrist Movements Using Only a Wrist-Worn, Inertial Measurement Unit: Toward Practical Wearable Sensing for Hand-Related Healthcare Applications

The ability to count finger and wrist movements throughout the day with a nonobtrusive, wearable sensor could be useful for hand-related healthcare applications, including rehabilitation after a stroke, carpal tunnel syndrome, or hand surgery. Previous approaches have required the user to wear a ring with an embedded magnet or inertial measurement unit (IMU). Here, we demonstrate that it is possible to identify the occurrence of finger and wrist flexion/extension movements based on vibrations detected by a wrist-worn IMU. We developed an approach we call “Hand Activity Recognition through using a Convolutional neural network with Spectrograms” (HARCS) that trains a CNN based on the velocity/acceleration spectrograms that finger/wrist movements create. We validated HARCS with the wrist-worn IMU recordings obtained from twenty stroke survivors during their daily life, where the occurrence of finger/wrist movements was labeled using a previously validated algorithm called HAND using magnetic sensing. The daily number of finger/wrist movements identified by HARCS had a strong positive correlation to the daily number identified by HAND (R2 = 0.76, p &lt; 0.001). HARCS was also 75% accurate when we labeled the finger/wrist movements performed by unimpaired participants using optical motion capture. Overall, the ringless sensing of finger/wrist movement occurrence is feasible, although real-world applications may require further accuracy improvements.

A rare case report of panuveitis with retinochoroidal involvement, retinitis, and retinal vasculitis due to extensive tinea corporis

A 40-year-old Asian Indian woman, diagnosed as having idiopathic panuveitis (elsewhere) 3 years earlier and being treated with oral steroids (20 mg/day) and methotrexate (25 mg/week), presented to us with worsening vision in both eyes. Her best corrected visual acuity (BCVA) was perception of light in her right eye and counting fingers close to face in her left eye. A slit lamp examination showed an anterior chamber (AC) reaction (1+) in both eyes with posterior synechia, a total cataract in her right eye, and pseudophakia in her left eye. The left fundus showed vitritis, vitreous membranes, chorioretinitis, multifocal areas of retinitis, and retinal vascular sheathing. A systemic examination showed extensive multifocal areas of tinea corporis on the hands and torso. Owing to the leukocytosis (22,000 cells/mm 3 ), diagnostic vitrectomy was initially deferred and 100 mg of oral itraconazole was given twice a day for 3 months. The vitritis improved a little and her total white blood cell (WBC) count improved with treatment of the skin infection. Following a diagnostic vitrectomy later in her left eye, resolving areas of retinitis were seen. Complete resolution of eye inflammation was seen at the end of 6 weeks. At the 6-month follow-up, her BCVA was 6/18 in left eye and she was off oral steroids and methotrexate, with no recurrence of inflammation. We speculate a probable association between the ocular inflammation and extensive tinea corporis based on the therapeutic response to itraconazole.
