Associations between dry eye disease and sleep quality: a cross-sectional analysis.

BACKGROUND/AIMS: To investigate relationships between dry eye (DE) disease and sleep quality, with a focus on which aspects of sleep most closely relate to DE. METHODS: 141 veterans (mean age: 56±5) seen at the Miami Veterans Affairs eye clinic filled out questionnaires to quantify the severity of DE symptoms (5-Item Dry Eye Questionnaire (DEQ-5) and Ocular Surface Disease Index (OSDI)) and ocular pain (Numerical Rating Scale (NRS) and Neuropathic Pain Symptom Inventory modified for the Eye (NPSI-E)). All individuals also underwent an ocular surface examination. Aspects of sleep quality were assessed using the Pittsburgh Sleep Quality Index (PSQI). DE metrics were examined by PSQI scores and subscores. RESULTS: Most participants (76%) reported mild or greater DE symptoms (DEQ-5 ≥6). Overall, ocular symptoms were more related to sleep metrics than signs. The strongest DE symptom association was between the OSDI and sleep disturbances (PSQI subscore 5, r=0.49, p<0.0005). For DE signs, ocular surface inflammation and meibum quality were related to subjective sleep quality (PSQI subscore 1, r=0.29, p=0.03, for both). On linear regression analyses, most ocular symptom questionnaires remained associated with sleep disturbances (PSQI subscore 5: NRS (r=0.52, p<0.0005), DEQ-5 (r=0.36, p<0.0005), and OSDI (r=0.31, p<0.0005)). For DE signs, ocular surface inflammation and meibum quality remained associated with subjective sleep quality (r=0.26, p=0.01; r=0.46, p<0.0005, respectively). CONCLUSION: DE symptom and ocular pain intensity were closely related to sleep metrics, most strongly to sleep disturbances. Relationships were weaker for DE signs, with subjective sleep quality relating to inflammation and meibum quality.

Ocular surface itch and pain: key differences and similarities between the two sensations.

PURPOSE OF REVIEW: To review the pathophysiology and treatment of ocular itch and pain, encompassing nociceptive and neuropathic categories. RECENT FINDINGS: Ocular itch and pain are sensations that arise from activation of ocular surface polymodal nerves. Nociceptive itch, commonly comorbid with ocular pain complaints, is mainly driven by a histamine-mediated type 1 hypersensitivity reaction. Beyond topical therapy, novel drug delivery systems are being explored to improve ocular residence time of nonsteroidal anti-inflammatory drugs (NSAIDs) and antihistamines. Nociceptive ocular pain can be driven by a variety of factors. Treatment focuses on addressing the causative sources of pain. Neuropathic ocular itch and pain are driven by nerve damage and dysfunction and as such, topical and oral neuromodulation have been explored as treatments. Oral neuromodulators include alpha 2 delta ligands, tricyclic antidepressants (TCAs), and low dose naltrexone. Novel therapies are being evaluated for both modalities such as difelikefalin (κ-opioid receptor agonist) for neuropathic itch and libvatrep (transient receptor potential vanilloid 1 antagonist) for neuropathic pain. SUMMARY: Both ocular itch and pain can be driven by nociceptive and/or neuropathic mechanisms. Identifying contributors to abnormal ocular sensations is vital for precise medical care. Novel therapeutics for these conditions aim to improve patient outcomes and quality of life.

Is gabapentin effective in dry eye disease and neuropathic ocular pain?

This study aims to evaluate the efficacy of gabapentin treatment in dry eye disease (DED) and neuropathic ocular pain. Our study was performed with 72 patients. The painDETECT questionnaire was used for neuropathic pain screening. Patients who were thought to have severe DED according to ocular surface disease index (OSDI) questionnaire, Schirmer's test type 1 and tear break up time test results were treated with artificial tear and cyclosporine drops. Gabapentin treatment was also initiated in addition to artificial tear and cyclosporine drops treatments to the patients with neuropathic component and DED findings. We divided the patients into two groups: group 1 (n: 36), patients treated with artificial tear and cyclosporine drops and group 2 (n: 36), patients treated with artificial tear, cyclosporine drops and gabapentin. In the first evaluation, no significant differences were found between groups in terms of OSDI score, Schirmer's test result and TBUT. After the 6 weeks of treatment, in both groups OSDI score, Schirmer's test result and TBUT statistically significantly improved. OSDI score, Schirmer's test result and TBUT significantly improved after the 6 weeks of gabapentin treatment than artificial tear and cyclosporine treatment group (p < 0.001). Dry eye patients should be screened for neuropathic ocular pain symptoms and individualized treatment has to be applied. Our study showed that the use of gabapentin is effective in severe dry eye patients with neuropathic ocular pain.

Differential diagnosis of acute ocular pain: Teleophthalmology during COVID-19 pandemic - A perspective.

Ocular pain is a common complaint which forces the patient to seek immediate medical attention. It is the primeval first response of the body to any severe condition of the eye such as trauma, infections and inflammation. The pain can be due to conditions directly affecting the eye and ocular adnexa; or indirect which would manifest as referred pain from other organ structures such as the central nervous system. Paradoxically, there are several minor and non-sight threatening conditions, which also leads to ocular pain and does not merit urgent hospital visits. In this perspective, we intend to provide guidelines to the practising ophthalmologist for teleconsultation when a patient complains of pain with focus on how to differentiate the various diagnoses that can be managed over teleconsultation and those requiring emergency care in the clinic. These guidelines can decrease unnecessary hospital visits, which is the need of the hour in the pandemic era and also beyond. Patients who are under quarantine and those who are unable to travel would be benefitted, and at the same time, the burden of increased patient load in busy hospital systems can be reduced.

Reduced Visual Quality of Life Associated with Migraine is Most Closely Correlated with Symptoms of Dry Eye.

BACKGROUND AND OBJECTIVE: Patients with migraine frequently report ocular or visual symptoms including aura, photophobia, and eye pain. Using validated instruments, our group previously reported that due to these symptoms, patients have marked reductions in visual quality of life. In chronic migraine, these reductions can be as substantial as those reported for other neuro-ophthalmic diseases such as multiple sclerosis with optic neuritis and idiopathic intracranial hypertension. Because the instruments take several different dimensions into account, we were unable to determine which ocular symptom(s) contributed to reduced visual quality of life. The purpose of this investigation was to attempt to determine which ocular symptom(s) were driving the observed reduction in visual quality of life. METHODS: We designed a cross-sectional survey-based study to assess visual quality of life, headache impact, aura, dry eye, and photophobia in migraine patients. Subjects were recruited from the Headache Clinic and General Neurology Clinic at a tertiary teaching hospital. Subjects completed validated questionnaires including: The visual functioning questionnaire-25 (VFQ-25), the headache impact test (HIT-6), the visual aura rating scale (VARS), the ocular surface disease index (OSDI), and the Utah photophobia score (UPSIS-17). Associations between VFQ-25 and OSDI, VFQ-25 and VARS, VFQ-25 and UPSIS-17, HIT-6 and OSDI, HIT-6 and VARS, and HIT-6 and UPSIS-17 were calculated. RESULTS: Of the 62 patients who completed all questionnaires, 17 had episodic migraine and 45 had chronic migraine. Twenty-three patients experienced aura and 39 did not report aura. The most striking correlations were observed between the VFQ-25 and the OSDI (-0.678; P < .001), between the HIT-6 and UPSIS-17 (0.489; P < .001), and between the HIT-6 and OSDI (0.453; P < .001). CONCLUSIONS: Dry eye seems to be the most important symptom that reduces visual quality of life and worsens headache impact. This symptom may be a form of allodynia, a well-known feature of chronic migraine. Photophobia appears to have modest effects on headache impact. In the future, we hope to determine whether treatment of dry eye symptoms can improve visual quality of life and reduce headache impact.

Efficacy of Care for Blind Painful Eyes.

PURPOSE: Pain relief for a blind painful eye often follows an escalating paradigm of interventions. This study compares the efficacy of common interventions. METHODS: A retrospective chart review of blind painful eye cases was conducted at a single tertiary institution from April 2012 to December 2016. Demographics, etiology, treatment, and pain level were assessed. RESULTS: Among 99 blind painful eyes, 96 eyes initially received medical therapy (topical steroids, cycloplegics, and/or hypotensives), with pain relief in 39% of eyes. Minimally invasive interventions (laser cyclophotocoagulation, retrobulbar injection, or corneal electrocautery) were performed 41 times in 36 eyes, 34 of which had failed medical therapy, and led to pain relief in 75% of eyes. Evisceration or enucleation was performed in 28 eyes, and long-term pain relief was achieved in 100% of eyes. Surgery allowed discontinuation of oral analgesics in 100% of cases versus 20% for minimally invasive therapy (p = 0.005) and 14% for medical therapy (p = 0.0001). Compared with medical therapy, minimally invasive therapy was 2.5 times more likely to achieve lasting pain relief (p = 0.003) and surgical therapy 35.6 times more likely to achieve lasting pain relief (p = 0.011). High initial pain score was associated with nonsurgical treatment failure. CONCLUSIONS: Medical therapy provides pain relief in a moderate number of patients with a blind painful eye. When medical therapy fails, minimally invasive therapy and surgical interventions are successively more effective in relieving ocular pain. High initial pain score is a risk factor for nonsurgical therapy failure and may merit an earlier discussion of surgical intervention.

Eye Pain and Dry Eye in Patients with Fibromyalgia.

Objectives: The aim of this study was to examine visual function and eye symptoms in fibromyalgia patients, with a particular focus on dry eye syndrome and eye pain. Methods: A tertiary care center-based cross-sectional study was carried out in chronic musculoskeletal pain patients diagnosed with fibromyalgia. Chronic musculoskeletal pain patients without fibromyalgia were enrolled as a comparison group. Self-reported eye pain was investigated with the McGill pain questionnaire and the numeric rating scale. In addition, we assessed corrected visual acuity, vision-related quality of life, and self-reported dry eye syndrome. Results: A total of 90 musculoskeletal pain patients were included, with 66 patients fulfilling American College of Rheumatology 1990 criteria for fibromyalgia. Sixty-seven percent (95% confidence interval [CI] = 56%-78%) of the fibromyalgia patients reported eye pain, and 62% (95% CI = 43%-81%) of those were without fibromyalgia diagnosis. Sixty-seven percent (95% CI = 56%-78%) of the fibromyalgia patients reported an experience of dry eye compared with 76% (95% CI = 57%-95%) in the nonfibromyalgia group. Vision-related quality of life was noticeably reduced in both groups. Conclusions: Eye pain and dry eye are common in chronic pain patients, with comparable prevalence in musculoskeletal pain patients with and without fibromyalgia.

Diplopia por barotrauma / Diplopia due to barotrauma

CASO CLÍNICO: Mujer de 38 años, que durante una inmersión a 7 m presenta dolor ocular, hiperemia y exoftalmos. Fue diagnosticada de barotrauma con diplopia transitoria. Acude a urgencias 10 días después sin diplopia, pero leve exoftalmos izquierdo. En la tomografía computarizada se observa imagen de ocupación extraconal en techo orbitario izquierdo. Posteriormente se realiza una resonancia magnética y se confirma la presencia de hematoma intraorbitario. Discusión: El barotrauma ocular es normalmente una condición benigna producida en su mayoría por inexperiencia del buceador. Sin embargo, es importante una exploración minuciosa para descartar lesiones potencialmente dañinas para la visión o para la vida

CASE REPORT: A 38-year-old woman who, during a scuba dive at 7 metres, suffered from eye pain, hyperaemia, and exophthalmos. She was diagnosed with ocular barotrauma with transient diplopia. She was seen in the emergency room 10 days later, with no diplopia, but mild left proptosis. In the computed tomography an image of extraconal occupation is observed in the left orbital roof. The magnetic resonance confirmed an intraorbital haematoma. Discussion: Ocular barotrauma is usually a benign condition mostly occurring in an inexperienced diver. However, a detailed examination is important to rule out potential vision and life threatening conditions

The Eye and Headache.

PURPOSE OF REVIEW: This article highlights painful conditions involving the eyes that are encountered in practice, emphasizing those that do not have obvious findings on the neurologic examination. RECENT FINDINGS: Peripheral and central sensitization are associated with chronic neuropathic ocular pain, and hyperalgesia is associated with dry eyes. The aorta and its branches are involved in 25% of patients with giant cell arteritis. SUMMARY: Eye pain is a common concern and one of the most difficult symptoms for the clinician to evaluate. Eye pain may be a manifestation of a primary headache disorder, as is common in migraine, the trigeminal autonomic cephalalgias, and primary stabbing headache. Secondary headache disorders, such as posterior communicating artery aneurysm, Tolosa-Hunt syndrome, and microvascular ocular motor neuropathies, frequently produce eye pain. Ophthalmic conditions producing eye pain include orbital masses, angle-closure glaucoma, intraocular inflammation, and ocular surface (corneal) disease. Of these, corneal problems are the most commonly encountered.

An update on eye pain for the neurologist.

Pain in and around the eye with or without an associated headache is a common presenting complaint to the neurologist. Although the main causes for eye pain are easily diagnosed by simple examination techniques that are readily available to a neurologist, sometimes the etiology is not as obvious and may require a referral to an ophthalmologist. This article summarizes and updates our prior review in Neurologic Clinics on this topic and includes (1) ocular and orbital disorders that produce eye pain with a normal examination, (2) neurologic syndromes with predominantly ophthalmologic presentations, and (3) ophthalmologic presentations of selected headache syndromes.

Keep an eye out for tubulo-interstitial nephritis.

Acute tubulo-interstitial nephritis and uveitis syndrome (TINU) is a rare disease, generally presenting in young women. We describe a 16-year-old Turkish girl with aspecific symptoms and elevated serum creatinine. Further, she complained about a burning pain in her left eye. Renal biopsy revealed acute TIN. Other conditions were excluded and TINU was diagnosed.

Ocular symptoms are not predictive of ophthalmologic inflammation in inflammatory bowel disease.

BACKGROUND: Ocular manifestations are frequent in patients with inflammatory bowel disease. AIM: To evaluate for the first time the value of ocular symptoms in predicting ophthalmologic inflammation in inflammatory bowel disease. METHODS: All consecutive inflammatory bowel disease patients seen in the Department of Gastroenterology (Nancy, University Hospital, France) between April 2009 and July 2011 were interviewed for this cross-sectional study using a pre-established questionnaire. If the patient had at least one ocular symptom, he systematically underwent an ophthalmologic examination (visual acuity, Break-Up Time test, Schirmer Test, slit-lamp exam with fundus examination). RESULTS: This cross-sectional survey was completed by 305 patients: 169 were women (55.2%), 228 had Crohn's disease (74.5%). Ninety-eight patients (32%) reported at least one ocular symptom: ocular irritation (56.8%), red eye (40.5%), blurred vision (37.8%), progressive visual loss (34.4%), ocular pain (31.1%), myodesopsia (23.3%), eyelid secretion (12.2%), dry eye (9.5%), watering (6.8%), diplopia (5.4%), metamorphopsia (4%), and sudden visual loss (4%). Following ophthalmologic examination (n=74), 41.9% patients had evidence of dry eye (n=31), 14.9% blepharitis (n=11) and 1.4% scleritis (n=1). No uveitis was reported. CONCLUSION: Ocular symptoms are frequent in inflammatory bowel disease, but are non-specific and rarely associated with ocular inflammation. Systematic ocular symptoms assessment is of poor value for diagnosing ocular inflammation in inflammatory bowel disease.

Dolor ocular: síntoma guía en la presentación de la celulitis orbitaria / Eye pain: presenting symptom of orbital cellulitis

La celulitis orbitaria es una infección localizada por detrás del septum orbitario. El origen de esta infección suele ser una complicación de una sinusitis. Los síntomas y signos que acompañan a la celulitis orbitaria varían según el grado de afectación de las estructuras intraorbitarias, pudiendo producir dolor ocular, quemosis, proptosis, oftalmoplejia y/o disminución de la agudeza visual. La sospecha clínica es muy importante, puesto que su pronóstico depende de la prontitud en su diagnóstico y tratamiento. Presentamos dos casos clínicos en los que el dolor ocular fue el síntoma de sospecha de celulitis orbitaria (AU)

Orbital cellulitis is an infection located behind the orbital septum. The origin of this infection is often a complication of sinusitis.The symptoms and signs that accompany orbital cellulitis depend on the extent of intraorbital structures and may produce eye pain, chemosis, proptosis, oftamoplejia or alteration of visual acuity. Clinical suspicion is very important because the prognosis depends on early diagnosis and its treatment. We present two cases in which ocular pain was the symptom of suspected orbital cellulitis (AU)

[Ocular pain. Differential diagnostic aspects]. / Augenschmerzen. Differenzialdiagnostische Aspekte.

Clinical ophthalmologists are often confronted with ocular pain, a symptom that can cause severe difficulties in the diagnostic assessment. The most common etiology is constituted by neurological disorders. Besides possible ophthalmologic causes for such disorders, otorhinolaryngological and oral and maxillofacial origins have to be considered. The ophthalmologist plays an important role as the first examiner, who has to rule out acute life-threatening conditions and also direct further steps in the differential diagnosis. This article clarifies such a diagnostic approach and discusses how a rudimentary knowledge of the characteristics of primary headaches is crucial as even though they do not induce ophthalmologic changes they constitute the main reason for the occurrence of ocular pain.

[Eye pain and headache from the perspective of an ophthalmologist]. / Augen- und Kopfschmerzen aus Sicht des Augenarztes.

Patients frequently contact ophthalmologists because of headache or eye pain. Pure ophthalmological disorders are rarely causative (e.g. asthenopia or diseases of the outer eye). It is very important to recognize symptoms and signs of the causative general or neurological disorders.

An unusual case of optic neuritis.

Optic neuritis is a frequent disease with well established tests and therapeutic strategies. However, possible differential diagnoses cover a broad spectrum. Therefore, clinical work-up can be challenging and routine testing and therapies may not be sufficient. In this case, a 26 year old female is described who presented with clinical features of optic neuritis, yet failed to respond to common therapeutic strategies and lost vision on the affected eye. Diagnostic nerve transection was performed, histopathology suggested inflammation. As the second nerve became affected, immunosuppressive therapy with cyclophosphamide was started and stopped further deterioration. Although additional molecular work-up of the transected nerve revealed clonal rearrangement of the B-cell-receptor-locus IgH, overall histopathologic features and the absence of systemic disease suggested an aggressive inflammatory process rather than lymphoma. Additional B-cell depletion with rituximab prompted significant and sustained visual improvement. This case emphasizes the necessity to consider rare differential diagnoses of optic neuritis, when uncommon features arise during the course of disease. Aggressive immunosuppression might be required to achieve stable improvement of vision.

The eye amputated - consequences of eye amputation with emphasis on clinical aspects, phantom eye syndrome and quality of life.

In this thesis the term eye amputation (EA) covers the removing of an eye by: evisceration, enucleation and exenteration. Amputation of an eye is most frequently the end-stage in a complicated disease, or the primary treatment in trauma and neoplasm. In 2010 the literature is extensive due to knowledge about types of surgery, implants and surgical technique. However, not much is known about the time past surgery. THE PURPOSE OF THE PHD THESIS WAS: To identify the number of EA, the causative diagnosis and the indication for surgical removal of the eye, the chosen surgical technique and to evaluate a possible change in surgical technique in Denmark from 1996 until 2003 (paper I); To describe the phantom eye syndrome and its prevalence of visual hallucinations, phantom pain and phantom sensations (paper II); To characterise the quality of phantom eye pain, including its intensity and frequency among EA patients. We attempted to identify patients with increased risk of developing pain after EA and investigated if preoperative pain is a risk factor for a later development of phantom pain (paper III); In addition we wanted to investigate the health related quality of life, perceived stress, self rated health, job separation due to illness or disability and socio-economic position of the EA in comparison with the general Danish population (paper IV). THE STUDIES WERE BASED ON: Records on 431 EA patients, clinical ophthalmological examination and an interview study of 173 EA patients and a questionnaire answered by 120 EA patients. CONCLUSIONS: The most frequent indications for EA in Denmark were painful blind eye (37%) and neoplasm (34%). During the study period 1996-2003, the annual number of eye amputations was stable, but an increase in bulbar eviscerations was noticed. Orbital implants were used with an increasing tendency until 2003. The Phantom eye syndrome is frequent among EA patients. Visual hallucinations were described by 42% of the patients. The content were mainly elementary visual hallucinations, with white or colored light as a continuous sharp light or as moving dots. The most frequent triggers were darkness, closing of the eyes, fatigue and psychological stress. Fifty-four percent of the patients had visual hallucinations more than once a week. Ten patients were so visually disturbed that it interfered with their daily life. Approximately 23% of all EA experience phantom pain for several years after the surgery. Phantom pain was reported to be of three different qualities: (i) cutting, penetrating, gnawing or oppressive (n=19); (ii) radiating, zapping or shooting (n=8); (iii) superficial burning or stinging (n=5); or a mixture of these different pain qualities (n=7). The median intensity on a visual analogue scale, ranging from 0 to 100, was 36 [range: 1-89]. One-third of the patients experienced phantom pain every day. Chilliness, windy weather and psychological stress/fatigue were the most commonly reported triggers for pain. Factors associated with phantom pain were: ophthalmic pain before EA, the presence of implant and a patient reported high degree of conjunctival secretion. A common reason for EA is the presence of a painful blind eye. However, one third of these patients continue to have pain after the EA. Phantom sensations were present in 2% of the patients. The impact of an eye amputation is considerable. EA patients have poorer health related quality of life, poorer self-rated health and more perceived stress than does the general population. The largest differences in health related quality of life between the EA patients and the general population were related to role limitations due to emotional problems and mental health. Patients with the indication painful blind eye are having lower scores in all aspects of health related quality of life and perceived stress than patients with the indication neoplasm and trauma. The percentage of eye amputated which is divorced or separated was twice as high as in the general population. Furthermore, 25% retired or changed to part-time jobs due to eye disease and 39.5% stopped participating in leisure activities due to their EAs.
