ABSTRACT
INTRODUCTION: Ocular rosacea is an underdiagnosed form of rosacea that may occur with or without typical cutaneous signs of rosacea. One of the common manifestations is dry eyes. Although the use of intense pulsed light (IPL) in the treatment of rosacea-related dry eyes has been reported, a recent review is lacking. METHODS: A scoping review was performed to summarize the efficacy of IPL in the treatment of ocular rosacea. RESULTS: Five articles were included, representing 108 patients, with a mean age of 58.4 years. Based on available data, 59.2% (n = 58/98) were female. The studies detailed the use of IPL in combination with meibomian gland expression treatment. Overall, 91% (n = 89/98) of patients with ocular rosacea treated with IPL had a partial response and 9% (n = 9/98) had no response. IPL therapy did not lead to complete recovery in any of the included patients. One participant experienced an adverse event across the included studies. CONCLUSIONS: IPL is a promising treatment modality for ocular rosacea, as demonstrated by its ability to relieve dry eye symptoms with limited adverse events. Further research into this novel treatment is necessary to ascertain its role in the management of ocular rosacea.
ABSTRACT
Rosacea is a common chronic skin disease distributed primarily around the central face. Ocular manifestations of rosacea are poorly studied, and estimates of prevalence vary widely, ranging from 6% to 72% in the rosacea population. Treatment options for ocular rosacea include lid hygiene, topical and oral antibiotics, cyclosporine ophthalmic emulsion, oral vitamin A derivatives, and intense pulsed light; however, a direct comparison of treatment methods for ocular rosacea is lacking. This review aims to compare treatment efficacy and adverse events for different treatment modalities in ocular rosacea. We performed a systematic review by searching Cochrane, MEDLINE and Embase. Title, abstract, full text screening, and data extraction were done in duplicate. Sixty-six articles met the inclusion criteria, representing a total of 1,275 patients. The most effective treatment modalities were topical antimicrobials and oral antibiotics, which achieved complete or partial response in 91% (n = 82/90) and 89% (n = 525/580) of patients respectively, followed by intense pulsed light (89%, n = 97/109 partial response), cyclosporine ophthalmic emulsion (87% n = 40/46), and lid hygiene (65%, n = 67/105). Combination treatments achieved a complete or partial response in 90% (n = 69/77). Results suggest that topical antimicrobials, oral antibiotics, intense pulsed light. and cyclosporine were the most efficacious single modality treatments.

PURPOSE: The purpose of this study was to describe a case of endogenous endophthalmitis (EE) after severe COVID-19 disease, review patient outcomes with EE after COVID-19 infection, and review evidence regarding risk factors for developing EE. METHODS: This is a review of health records, imaging, intravitreal injection, and pars plana vitrectomy for bilateral fungal EE after severe COVID-19 disease, and is a literature review on outcomes in EE after COVID-19 disease. RESULTS: Sixty-three year-old man with diabetes and hypertension was admitted to hospital for severe COVID-19 disease for 3 months. His stay required intensive care unit admission, intubation, high-dose corticosteroids, tocilizumab, and was complicated by bacteremia, empyema, and fungal esophagitis. He developed floaters and bilateral vision loss (visual acuity 20/40 in the right eye, counting fingers in the left eye) with vitritis 2.5 months into his stay that did not respond to intravitreal voriconazole. Pars plana vitrectomy was performed for both eyes, resulting in visual acuity of 20/40 in the right eye, 20/30 in the left eye. Vitreous cultures were positive for Candida albicans . Endogenous endophthalmitis after COVID-19 disease has been reported in 22 patients to date, and outcomes are poor, with 40%+ of eyes legally blind (20/200 or worse). Although influenced by availability of imaging modalities and degree of training of the evaluating physician, misdiagnosis can affect » of cases, delaying treatment. Age, male sex, and diabetes increase the risk of severe COVID-19, which requires prolonged hospitalization, invasive catheterization, and immunosuppression, which in turn increases the risk of nosocomial infection. CONCLUSION: Low threshold for suspecting EE in patients presenting with floaters and decreased vision after severe COVID-19 disease is necessary to ensure prompt recognition and treatment.

BACKGROUND: Up to 1/3 of patients with herpes zoster ophthalmicus (HZO) may develop ophthalmoplegia. Although zoster-related ophthalmoplegia (ZO) is typically treated with antiviral agents, there is controversy regarding the therapeutic role of systemic steroids. METHODS: This was a retrospective case series and case report-based systematic review. For the case series, participants were recruited from tertiary neuro-ophthalmology clinics. Eligible participants were those who developed cranial nerve palsies (CNP) within 1 month of HZO diagnosis. In the systematic review, all adults with ZO in the literature who were treated with antivirals or steroids only, or combination therapy were included. Main outcomes were initial presentation, investigations, neuroimaging, treatment regimen, and final outcomes of ophthalmoplegia. RESULTS: Eleven immunocompetent patients with ZO were included. The most common CNP was CN III (5/11), followed by CN VI (2/11) and CN IV (2/11). One patient had multiple CNPs. All patients were treated with antivirals, and 4 also treated with a short course of oral steroids. At 6-month follow-up, 75% of patients treated with combination therapy and 85.7% treated with antivirals alone had complete recovery of ZO. The systematic review identified 63 studies consisting of 76 cases of ZO. When comparing patients treated with antivirals with those treated with antivirals and steroids, patients on combination therapy had more severe ocular findings, including complete ophthalmoplegia (P < 0.001). Age was the only significant predictor of complete recovery of ophthalmoplegia on multivariable logistic regression (P = 0.037). CONCLUSIONS: The rate of complete recovery in immunocompetent patients with ZO was similar in patients treated with antivirals alone vs those treated with antivirals and oral steroids. The systematic literature review affirmed these findings. However, age may influence recovery of ophthalmoplegia.
ABSTRACT
BACKGROUND: To compare the rate of retinal atrophy over time in patients with relapsing-remitting multiple sclerosis (RRMS) treated with various disease-modifying therapies (DMT). METHODS: Patients with RRMS on various DMT and those observed without treatment were prospectively enrolled into the study between September 2015 and June 2018. All subjects with follow-up of 1-4 years were included and categorized into groups as "no drug", "low efficacy drug", "high efficacy drug", or "dimethyl fumarate" (DMF), based on treatment modality used for the longest duration of their follow-up. Ocular coherence tomography (OCT) was used to measure peripapillary retinal nerve fiber layer thickness (RNFL) and ganglion cell/inner plexiform layer (GC-IPL) thickness at baseline and every 6 months. A linear mixed effects regression model was performed to compare rates of retinal atrophy across treatment groups. RESULTS: Out of 67 participants who met inclusion criteria (mean age = 37; 76% female), 13 were untreated, 12 on low efficacy therapy, 18 on DMF, and 24 on high efficacy therapy. History of optic neuritis was associated with lower baseline GC-IPL thickness (p = 0.003). Higher baseline GC-IPL thickness was associated with increased rate of GC-IPL thinning (p = 0.009). Age, disease duration, and ethnicity were not predictors of baseline RNFL or GC-IPL thickness, or rate of atrophy of these layers. CONCLUSIONS: There were no differences in rate of GC-IPL atrophy between patients with RRMS on different treatments in this cohort. Age, disease duration, and ethnicity also did not predict retinal atrophy. History of ON was associated with reduced GC-IPL thickness at baseline, consistent with previous research. Rate of GC-IPL thinning was higher for subjects with higher baseline GC-IPL thickness, suggesting a plateau effect.

Choroidal neovascularization (CNV) affects 64-75% of eyes with punctate inner choroidopathy (PIC). Although anti-VEGF agents are considered first-line therapy, there is controversy regarding other modalities, such as immunosuppression. We performed a systematic review of individual participant data (IPD) and generated a dataset of 278 eyes with PIC-related CNV from 45 studies. Forty-two percent presented with moderate visual loss (MVL) or worse. Four different treatment modalities (anti-VEGF, photodynamic therapy, local immunosuppression, and systemic immunosuppression) and most combinations among them were represented. Anti-VEGF injections decreased the likelihood of MVL (Odds Ratio 0.3, p = .027), an effect moderated by presenting visual acuity and patient age. Eyes receiving more than 3 injections were more likely to receive additional therapeutic modalities. Increasing number of modalities was associated with longer follow-up time and did not improve vision. The beneficial effect of anti-VEGF injections persisted when controlling for presenting visual acuity and follow-up time.

Background: This review summarizes the literature on sleep quality in neuromyelitis optica spectrum disorder (NMOSD) and discusses these findings in the context of current knowledge of sleep physiology. Methods: A literature search was performed using Ovid MEDLINE, Embase, and Scopus from inception to September 3, 2020. All included studies reported at least 1 measure of sleep quality in individuals with NMOSD. Pittsburgh Sleep Quality Index (PSQI) scores of individuals from 4 studies were compared with those from a data set of controls. Results: Thirteen studies (1041 individuals with NMOSD) were included in the review. Disturbed sleep was demonstrated across subjective metrics based on patient surveys and objective metrics such as polysomnography. An estimated 70% of individuals with NMOSD can be classified as poor sleepers. Standardized mean difference between PSQI scores of 183 individuals with NMOSD and those of 9284 controls was 0.72 (95% CI, 0.57-0.86; P < .001). Decreased sleep quality was significantly associated with decreased quality of life and increased anxiety, depression, and disability status. Sleep disturbances in NMOSD were similar in severity to those in multiple sclerosis. Conclusions: Sleep disturbances are a major contributor to NMOSD disease burden and may arise from the disruption of sleep circuitry, in addition to physical and psychological complications. Multiple processes involved in sleep regulation may be affected, such as, but not limited to, neural circadian circuit disruption, direct effects of inflammation, aminergic projecting system abnormalities, glymphatic system impairment, and development of sleep disorders such as restless legs syndrome/sleep apnea. A better understanding of these mechanisms is necessary for developing effective therapies for NMOSD-associated sleep disturbances.

Hypertrophic scars (HTS) are elevated scars which occur due to abnormalities in wound healing after injury and may be associated with pain, pruritus and functional impairment. Despite multiple available treatment options, there is no universal approach to treating HTS. We searched the Web of Science (Core Collection), MEDLINE and EMBASE databases. Title, abstract and full-text screening, along with data extraction, were performed in duplicate. Risk of bias was assessed using the Cochrane risk-of-bias tool. The Vancouver Scar Scale (VSS) scores and mean differences were used for meta-analysis. We screened 3800 abstracts and included 34 randomised controlled trials evaluating treatments for HTS in adults. Silicone and laser modalities improved VSS scores by 5.06 (95% CI: 6.78, 3.34) and 3.56 (95% CI: 5.58, 1.54), respectively. Intralesional triamcinolone combined with silicone or 5-fluorouracil was superior to intralesional triamcinolone monotherapy. Limitations of this study include exclusion of studies which did not utilise VSS, and pooling of studies based on common modalities. Further studies are needed to examine the efficacy of existing and emerging treatment modalities for HTS. Our study supports the treatment of HTS in adults with silicone gel or sheets, injected triamcinolone (preferably combined with 5-fluorouracil or silicone products), pulsed dye laser and fractionated CO2 laser.

BACKGROUND: To assess patients with indirect carotid-cavernous fistulas (CCF) for evidence of hypercoagulable state (HS) by combination of comprehensive medical questionnaire and laboratory testing. METHODS: Patients with confirmed diagnosis of CCF treated between 2003 and 2019 were included and administered a questionnaire screening for HS risk factors and undergone laboratory investigations which included complete blood count (CBC), prothrombin time (PT), partial thromboplastin time (PTT), fibrinogen, antiphospholipid antibodies (lupus anticoagulant and anticardiolipin antibody titres), Factor V Leiden, prothrombin, protein C, protein S, antithrombin III, homocysteine, prothrombin G20210, CALR and JAK2 mutation screening. Participants with abnormal laboratory testing and/or past history of ischemic stroke, atrial fibrillation, cancer or hypercoagulability-associated hereditary disorders were deemed to have HS. RESULTS: Twenty-two patients were enrolled. Seventeen were women and the mean age at diagnosis was 60. Fourteen (64%) had evidence of HS: six on medical history, three with laboratory evidence and five with both. Eight (36%) had current abnormal hypercoagulability markers. One had a diagnosis of Klippel-Trenaunay Syndrome, but no others had evidence of hereditary thrombophilia. Nine were on anti-coagulation initiated after diagnosis of stroke or atrial fibrillation discovered on average 5.5 years after the diagnosis of CCF. CONCLUSION: A total of 64% percent of patients with previous indirect CCF had evidence of underlying HS indicating that hypercoagulability might play a role in the pathogenesis of CCF. The results support need for comprehensive testing for underlying HS in patients with indirect CCFs to better identify, manage, and prevent further thromboembolic events.

BACKGROUND: We aimed to investigate whether the degree of transverse sinus stenosis (TSS) on magnetic resonance venography (MRV) can predict visual outcomes in patients with idiopathic intracranial hypertension (IIH). METHODS: A chart review identified IIH patients followed for at least 6 months. Mean deviation (MD) on visual field (VF) testing at initial and last follow-up visits, best corrected visual acuity (BCVA), patients' age, body mass index, and lumbar puncture opening pressure were recorded. MRV was used to grade TSS on a scale of 0-8 using the grading scheme proposed by Farb et al., whereby a lower score indicates a greater degree of stenosis. Linear regression analysis was used to test for association between above variables and MD on VF, including change in MD over time. RESULTS: 44 female patients were followed for a median of 26 months. All patients had unilateral or bilateral TSS on MRV. The median TSS score was 3/8. The median BCVA was 0.06 logMAR at baseline. The median VF MD was -3.02 dB at baseline and -1.96 dB at final follow-up. There was no significant association between the degree of TSS and either baseline MD (P-value = 0.34) or the change in MD on VF over the course of follow-up (P-value = 0.54). Baseline BCVA (P = 0.045) and baseline MD (P < 0.001) were the only significant predictors of changes in MD on VF over follow-up. CONCLUSIONS: Baseline BCVA and MD on VF were the only significant predictors of visual outcome in IIH patients. While all patients demonstrated TSS on MRV, the degree of TSS did not correlate with visual prognosis.

BACKGROUND: Leber's hereditary optic neuropathy (LHON) is a disorder affecting oxidative phosphorylation in mitochondria. A majority of affected patients are men of 15 to 35 years of age. Phenotypic penetrance of this condition is only 50% in man and 10% in women and increases if the cellular energy demands go up, with the most common risk factors being smoking and alcohol use. METHODS: Review of clinical features of 3 patients who were diagnosed with LHON in their sixth decade of life after doubling their alcohol intake during the recent COVID-19 pandemic. RESULTS: All 3 patients were older than the age of 50 when they developed severe sequential visual loss. All have at least doubled their alcohol intake for at least 4 weeks preceding visual loss, and 2 who were smokers increased the number of cigarettes consumed daily because of the stress and boredom during the lockdowns triggered by the pandemic. CONCLUSIONS: Significant increase in substance abuse in the general population during the recent lockdowns to combat the COVID-19 pandemic is well documented. We report 3 patients older than the age of 50, one of them a woman, who developed severe bilateral visual loss due to LHON after doubling their alcohol consumption and increasing number of cigarettes smoked daily during the pandemic. Clinicians are reminded to consider LHON in the differential diagnosis when encountering older patients with bilateral sequential visual loss and to specifically inquire about alcohol use and cigarette smoking in these patients.

ABSTRACT: A 58-year-old man noticed shadows in the temporal visual field of each eye and photopsias within these scotomas for the past year. Formal visual fields demonstrated bitemporal hemianopia. MRI of the sella was normal, but fundus autofluorescence (FAF) demonstrated an area of hyperautofluorescence in the nasal retina of each eye corresponding to the loss of retinal pigment epithelium and photoreceptors. A diagnosis of acute zonal occult outer retinopathy was made based on the presence of trizonal involvement on FAF. This case is a reminder that bitemporal hemianopia can be caused by a retinopathy involving nasal retina in each eye, and FAF is a very useful test when assessing patients with suspected outer retinal disorders.
