Novel tactile bottle neck adaptor facilitates eye drop adherence in visually impaired patients.

PURPOSE: To test the use of Ring-IT, a novel 3D tactile bottle neck adaptor in topical eye drop adherence in visually impaired patients. METHODS: Bottle neck ring adaptors with either one, two or three protrusions with cube or sphere endings were designed. In phase 1, low vision was simulated in healthy subjects (n=20) with a 20/200 vision simulator; while in phase 2, visually impaired patients (n=26; 20/70 or worse) were recruited. Subjects were randomised to six combinations of varying protrusions and shapes on medication bottles and asked to identify these traits at different presentations. Responses and time to identify were recorded. RESULTS: Phase 1: 98.3% of subjects correctly identified the number of protrusions. Mean time to identify was 4.5±6.1 s. Identification success for cube and sphere end pieces were 91.7% and 73.3%, with average time for identification of 9.9±7.6 and 10.9±9.0 s. In phase 2, 92.3% of subjects correctly identified the number of protrusions. Mean time to identify was 6.0±3.0 s. Identification success for cube and sphere end pieces were 78.2% and 74.4%; with average time for identification of 7.5±4.8 and 8.5±5.6 s, respectively. CONCLUSIONS: Ring-IT was identified with accuracy and speed by both low vision simulated subjects, and by patients with true limited visual capabilities. These tactile bottle neck ring adaptors can be used as an assistive low vision aid device and may increase eye drop regimen adherence in visually impaired patients.

Assessment of Visual Acuity Outcomes in Ocular Syphilis Treated With Adjunctive Topical or Oral Steroids.

PURPOSE: There is no consensus surrounding adjunctive steroid use in the treatment of ocular syphilis. We evaluated clinical outcomes of patients with ocular syphilis who were treated with penicillin plus either topical or oral steroids. METHODS: Nine male patients aged 26 to 72 years with a diagnosis of ocular syphilis were retrospectively identified (18 eyes). All patients were treated with penicillin and adjunctive topical or oral steroids. Visual acuity reported as the logarithm of the minimum angle of resolution (logMAR) and slit lamp findings were documented at presentation, short-term follow-up (<7 days after initiating therapy), and long-term follow-up (day 7+). Visual acuity outcomes were compared between eyes treated with topical versus oral steroids as well as eyes treated simultaneously with adjunctive steroids and penicillin versus patients treated with steroids after penicillin. RESULTS: At short-term follow-up, the mean logMAR (SD, Snellen fraction) visual acuity for eyes treated with topical steroids 0.93 (0.53, 20/170) was significantly lower than that for the oral steroid group 0.23 (0.09, 20/110; p=0.0075). Similarly, at long-term follow-up, the topical steroid group had a significantly lower visual acuity of 0.75 (20/112) compared to a visual acuity of 0.07 (20/25) for the oral steroid group (p=0.0022). Moreover, the oral steroid group displayed significant improvement in visual acuity at long-term follow-up compared to baseline while the topical steroid group did not demonstrate the same effect (p=0.0406 and p=0.5945, respectively). Initiation of steroid treatment simultaneously with penicillin did not result in better visual acuity than delayed steroid treatment (p>0.05). CONCLUSIONS: Steroids are an effective adjunctive treatment for patients with ocular syphilis. Oral steroids may be superior to topical steroids for improving visual function, especially in patients with a severe inflammatory component. Patients treated with oral or topical steroids and penicillin simultaneously did not demonstrate better visual acuity outcomes than patients treated with oral or topical steroids after penicillin was initiated.

Acute idiopathic blind spot enlargement syndrome (AIBSES) with retinal vasculitis.

Purpose: To report the clinical and anatomical features of an unusual case of acute idiopathic blind spot enlargement syndrome (AIBSES) with retinal vasculitis. Observations: A 39-year-old patient, who was a known case of chronic headache with nonspecific visual symptoms for nine years, developed scotomas in her right eye. She was initially diagnosed with AIBSES which had been stable, but later worsened with symptoms of subsequent blind spot enlargement and photopsia on the left eye a year later. Increase in the size of the blind spot over the left eye and stability of the blind spot enlargement over the right eye was documented on Humphrey visual field (HVF) testing. Due to the rapid onset and severity of symptoms, an inflammatory etiology was entertained and this prompted referral to our clinic. At initial presentation, fluorescein angiogram (FA) revealed moderate diffuse vasculitis and disc leakage in the left eye, which existed alongside the enlarged blind spot. Corticosteroid treatment was suggested and initiated. The patient was found to have a reduction in the size of her blind spot and a decrease in severity of retinal vasculitis a month later. Unfortunately, the patient was then lost to follow up and had stopped steroid treatment of her own accord. After nine months without treatment, the patient's blind spot increased to a larger size than her initial presentation, as documented on HVF, with recurrence of vasculitis in the left eye. Conclusion and Importance: This is an unusual case of AIBSES which presented with vasculitis and rapid progression and has responded to steroids. Though monocular AIBSES has been shown to later affect the contralateral eye, concurrent vasculitis with AIBSES has not previously been reported. Furthermore, the response to treatment with reduction in blind spot enlargement is unusual for AIBSES. These findings stress the need for regular monitoring in cases of AIBSES.

Chloropsia in the Charles Bonnet syndrome.

Purpose: Chloropsia (green-colored vision) is an extremely uncommon and relatively unstudied clinical finding. We report a case where cerebral chloropsia was the presenting symptom of the Charles Bonnet syndrome. Observations: A 66-year-old male physician with a previous ocular history of advanced bilateral primary open-angle glaucoma presented with acute, diffuse chloropsia, which he described as "light green and oval-shaped." The patient was not taking any drugs that commonly cause altered color perception and did not have a previously diagnosed psychiatric disorder. Ophthalmic examination findings showed poor visual acuity, central visual field loss, and altered color perception in both eyes. Common laboratory tests and visual imaging showed no abnormalities that could be associated with the patient's symptoms. Conclusions and Importance: Our patient meets all diagnostic criteria for Charles Bonnet syndrome, even though, to the best of our knowledge, chloropsia has never been previously associated with this disorder. Physicians should monitor patients for altered color perception, which cannot be explained by other ocular, psychiatric, or systemic mechanisms, as this could be a sign of Charles Bonnet syndrome.

Secondary Syphilis Presenting as Bilateral Simultaneous Papillitis in an Immunocompetent Individual.

Ocular syphilis is a common presentation for patients with secondary or tertiary syphilis and usually includes posterior uveitis or panuveitis, though a myriad of symptoms have been associated. We report the case of a 58-year-old Caucasian male who presented with fast-progressing vision loss and a new onset of floaters in both eyes. An initial fundus exam revealed only bilateral optic disc edema, and neurological evaluation was negative. Subsequent ophthalmology evaluation in the clinic revealed a ragged retinal pigmented epithelium on optical coherence tomography (OCT) and posterior placoid chorioretinitis, raising suspicion of syphilis. Intravenous penicillin therapy was immediately initiated based on high clinical suspicion of ocular syphilis while awaiting lab confirmation, which was later confirmed as a new syphilis infection. He was subsequently given oral prednisone 48 hours into penicillin therapy for a significant posterior inflammatory response in both his eyes. His visual recovery was drastic due to the timely use of oral steroids. Classical findings such as ragged retinal pigmented epithelium on OCT and posterior placoid chorioretinitis demonstrate strong clinical suspicion of ocular syphilis. Oral prednisone when used timely with penicillin therapy in special situations such as bilateral severe posterior uveitis, panuveitis, or optic neuritis may aid in a faster and smoother visual recovery. A high index of clinical suspicion of ocular syphilis should be maintained in patients with human immunodeficiency virus (HIV) infection presenting with uveitis, posterior placoid morphology, or optic disc edema. Oral prednisone may be an effective adjuvant treatment for immunocompetent patients who mount a strong inflammatory response to ocular syphilis infection.

The Prevalence of Work-Related Musculoskeletal Disease Among Pediatric Ophthalmologists.

Introduction: Work-related musculoskeletal disease (MSD) is the second leading cause of disability globally. Ophthalmologists widely report MSDs in the neck (70%) and back pain (40-80%). Our study intended to identify the prevalence of MSDs among pediatric ophthalmologists. Methods: Pediatric ophthalmologists self-reported chronic pain, instrumentation used, years practiced, surgeries performed, work schedule/environment modifications due to MSD, and treatment for MSD via an anonymous online survey. Statistical analysis of responses included odds ratios, Pearson chi-square testing, and Spearman correlations. Results: This study had 101 respondents, with 66% reporting chronic pain. Chronic neck pain (41%) and lower back pain (31%) followed by shoulder pain (30%) were the leading MSD complaints and significantly correlated with years of experience (p<0.05). Participants often had multiple types of pain, including 13% of the sample who experienced all three types of pain. Those reporting shoulder and back pain also reported a greater incidence in work modification (68-83%). Those suffering from chronic neck, shoulder, and lower back pain have sought treatment for their MSD (p<0.05). Discussion: With such wide reporting of chronic neck, back, and shoulder pain, the development of MSDs likely leads to disability. Ergonomic innovations in the workplace may reduce the healthcare burden and prolong pediatric ophthalmologists' ability to provide services. Conclusion: In our study, the reported prevalence of chronic neck and back pain was comparable to previous studies and published literature, with 2/3 of participants reporting pain. There is a tremendous need for ongoing innovations, especially surgical loupes, operating microscopes, and slit-lamp modifications to prevent musculoskeletal disease.

Feasibility of rapid magnetic resonance imaging (rMRI) for the emergency evaluation of suspected pediatric orbital cellulitis.

PURPOSE: To determine the feasibility of noncontrast rapid magnetic resonance imaging (rMRI), compared with traditional contrast-enhanced computed tomography (CT) in assessing pediatric emergency department patients with suspected orbital cellulitis or orbital abscess. METHODS: All subjects <19 years of age who presented emergently with suspected orbital cellulitis from July 1, 2017, to July 31, 2019, were included. Participants received both the standard contrast orbital CT, if deemed necessary, with the addition of the noncontrast rMRI after informed consent was obtained. No sedation was used for either examination. All clinical decisions were based on CT findings; rMRI was interpreted within 24 hours of the visit. Three pediatric radiologists, with 8-21 years' experience of pediatric neuroradiology, interpreted the rMRI, masked to the CT and clinical results. Results were analyzed for interobserver bias. RESULTS: A total of 14 patients were enrolled during the study period. Mean age was 5.9 years (range, 0.33-13). Of the 14 patients, 13 (93%) were able to complete the rMRI at 1.5 and 3T; 1 patient (1.67 years of age) was unable to complete the rMRI (no images obtained). Of the 26 unilateral orbital units assessed, 3 were positive for retroseptal orbital cellulitis by CT and were diagnosed correctly by rMRI. Interobserver agreement was 100% in detecting presence or absence of retroseptal cellulitis. CT and rMRI findings were concordant in 100% of cases in differentiating preseptal vs orbital cellulitis. Kappa statistics for three-category ratings by three raters for right eye/orbit was 0.921 and for left eye/orbit was 0.9288, suggesting almost perfect agreement. Concordance correlation coefficients were 0.938 for the right eye and 0.955 for the left eye. CONCLUSIONS: Noncontrast rMRI orbits showed findings concordant in all cases with contrast-enhanced CT for differentiating preseptal cellulitis from orbital cellulitis.

Orbital pseudotumor as the presenting symptom of Crohn's disease in a male child.

PURPOSE: This report will describe a case of orbital pseudotumor that is associated with underlying Crohn's disease in a pediatric patient. OBSERVATIONS: An 8-year-old male with a past medical history of chronic constipation who presented to the ophthalmologist in July 2017 with a 7-month history double vision, left upper lid ptosis, left abducens nerve palsy, and an abnormal thyroid test. The patient's family history was negative for any autoimmune disease including, juvenile idiopathic arthritis, rheumatoid arthritis, thyroid disease, type 1 diabetes mellitus or inflammatory bowel disease. Diagnosis of orbital pseudotumor of the left eye was made based on CT scan findings and he was then treated with a one-week course of oral prednisone. After resolution of his initial symptoms, he presented a month later with swelling in his left eye and was treated with a 6-month steroid taper with resolution of symptoms. In June 2018, the patient presented with swelling in his right eye and was treated with prednisone plus steroid sparing agents. Extraocular muscle biopsy was negative for IgG4 related disease, fungal infection, or malignant lymphoma and workup for sarcoidosis and granulomatosis with polyangiitis was unremarkable. In September 2018, the patient presented with bloody stools, diagnosed and treated for a perirectal abscess. Subsequent colonoscopy performed in January 2019 confirmed Crohn's disease. He is currently undergoing treatment with adalimumab and is in remission in terms of orbital pseudotumor. CONCLUSION AND IMPORTANCE: In conclusion, although the association between orbital pseudotumor and Crohn's disease is very rare, medical professionals should remember this connection when a patient presents with idiopathic orbital pseudotumor. To rule out this possibility, we recommend a thorough history of GI findings should be taken on the initial patient encounter. Crohn's disease may be an underlying cause of certain cases of orbital pseudotumor, and treatment and control of the underlying Crohn's disease may help to reduce recurrence rates of orbital pseudotumor. Additional studies need to be performed to better understand the association between the two diseases.

A Rare Case of Syndrome of Inappropriate Anti-diuretic Hormone in Non-small Cell Lung Cancer Presenting as Superior Vena Cava Syndrome.

Syndrome of inappropriate anti-diuretic hormone (SIADH) secretion is uncommon in small cell lung cancer (SCLC), but even more rare in cases of non-small cell lung cancer (NSCLC). We report a case of a 59-year-old male who presented with superior vena cava (SVC) syndrome. After further investigation, he was diagnosed with adenocarcinoma of the lung. He delayed his medical care and his condition worsened. He was diagnosed with SIADH as an incidental finding on routine lab draw. Radiotherapy was subsequently initiated, and after one week of treatment, the patient showed marked clinical improvement. In this article, we also review the current indications for radiotherapy in various lung cancers and the management of SIADH.
