Abstract
OBJECTIVES Corneal abrasions are common ophthalmic presentations to emergency departments. Among emergency physicians and ophthalmologists, there are highly variable practice patterns with regard to management of resultant pain and discomfort. The goal of this study was to review and analyze the efficacy and safety of topical pain therapies for corneal abrasions, including topical anesthetics, nonsteroidal anti-inflammatory drugs (NSAIDs), cycloplegics, steroids, pressure patching, and the use of a bandage contact lens (BCL). METHODS The review followed the Preferred Reporting Items for Systematic Review and Meta-analysis (PRISMA) guidelines. The protocol was established a priori and published on PROSPERO (CRD42020201288). MEDLINE, EMBASE, CENTRAL, and Web of Science were searched until December 31, 2020. Primary studies comparing topical pain therapies to another therapy or control were included. Primary outcomes included percentage of corneal abrasions healed at 24, 48, and 72 hours, as well as pain control at 24 and 48 hours. Secondary outcomes included use of oral analgesia and incidence of complications. Risk of bias was assessed using validated tools. Quality of evidence was assessed using the GRADE methodology. RESULTS Overall, 33 studies (31 randomized controlled trials [RCTs], two cohort studies) comprising 4,167 patients with corneal abrasions were analyzed. Only the data for topical NSAIDs were of adequate evidence from which to draw conclusions; topical NSAIDs demonstrated significantly reduced pain scores at 24 hours (standardized mean differences [SMD] -0.69, 95% CI = -0.98 to -0.41) and 48 hours (SMD = -0.56, 95% CI = -1.02 to -0.10) as well as 53% (95% CI = 34% to 67%) lower oral analgesia use compared to control. Based on available data, topical anesthetics, cycloplegics, patching, and the use of a BCL did not result in any significant difference in pain scores or use of oral analgesia, while no studies examined topical steroids. No interventions resulted in healing delays or significantly higher rates of complications compared to controls. CONCLUSIONS There was strong evidence to support that topical NSAIDs reduce pain associated with corneal abrasions in the first 48 hours and the need for oral analgesia. The existing evidence was insufficient to support or refute the use of topical anesthetics, cycloplegics, steroids, or BCL for pain control in corneal abrasions. Pressure patching was ineffective at pain reduction and may increase the risk of complications. Delays in healing or other complications were not significantly different between any intervention or control for simple, uncomplicated corneal abrasions; however, larger RCTs are required to identify any differences in rare complications.

Abstract
Ocular complications from diabetes mellitus are common. Diabetic keratopathy, the most frequent clinical condition affecting the human cornea, is a potentially sight-threatening condition caused mostly by epithelial disturbances that are of clinical and research attention because of their severity. Diabetic keratopathy exhibits several clinical manifestations, including persistent corneal epithelial erosion, superficial punctate keratopathy, delayed epithelial regeneration, and decreased corneal sensitivity, that may lead to compromised visual acuity or permanent vision loss. The limited amount of clinical studies makes it difficult to fully understand the pathobiology of diabetic keratopathy. Effective therapeutic approaches are elusive. We summarize the clinical manifestations of diabetic keratopathy and discuss available treatments and up-to-date research studies in an attempt to provide a thorough overview of the disorder.

Abstract
Persistent corneal wounds result from numerous eye disorders, and to date, available treatments often fail to accelerate reepithelialization, the key initial step in wound healing. To speed reepithelialization, we explored a cell-transfer transplant method utilizing polydimethylsiloxane (PDMS) contact lenses to deliver epithelial cells derived from limbal explants directly within a corneal wound. Human primary epithelial cells and an immortalized corneal epithelial cell line (HCE-SV40) grew well on PDMS contact lenses and their morphology and growth rates where similar to cells grown on tissue culture polystyrene. To initially study cell transfer from PDMS, HCE-SV40 cells were seeded onto PDMS with or without micropatterned posts. After a day in culture, HCE-SV40 cells attached to the unpatterned PDMS uniformly, whereas on micropatterned PDMS they appeared to attach primarily between posts. The cell-covered PDMS contacts were then placed cell-side down onto tissue culture plastic and, after 1, 2, or 3 days, the PDMS contact was removed and the transferred cells were trypsinized and counted. Micropatterned PDMS contact lenses with 100-μm-diameter posts and a post height of 40 μm transferred three times as many cells as unpatterned PDMS. Cell transfer to a wounded cornea was tested in a pig cornea organ culture model deepithelialized by alkali treatment. Post micropatterned PDMS contact lenses were seeded with labeled HCE-SV40 cells at a density 50,000 cells/cm2 and applied to the wounded pig corneas. After 24, 48, or 96 h of application, PDMS contact lenses were removed, corneas fixed with formaldehyde, and sectioned. After 48 h, epithelial cells transferred from post micropatterned contact lenses to provide 35% epithelial coverage of denuded pig corneas; after 96 h coverage was 65%. We conclude that cell transfer from epithelial-coated PDMS contact lenses micropatterned with posts provides a promising approach to reepithelialize corneal surfaces.

Abstract
Corneal abrasion is the most common ocular complication in surgery. Treatment requires pain control, antimicrobial prophylaxis, and close monitoring. Pain improves significantly after 24 hours and should be resolved by 48 hours. Persistent, worsening, or new symptoms warrant immediate specialist consultation. The authors review the pathophysiology of perioperative corneal abrasion, and propose updated evidence-based guidelines for improved patient care.

Abstract
BACKGROUND Published audits have demonstrated that corneal abrasions are a common presenting eye complaint. Eye patches are often recommended for treating corneal abrasions despite the lack of evidence for their use. This systematic review was conducted to determine the effects of the eye patch when used to treat corneal abrasions. OBJECTIVES The objective of this review was to assess the effects of patching for corneal abrasion on healing and pain relief. SEARCH METHODS We searched CENTRAL (which contains the Cochrane Eyes and Vision Trials Register) (2016, Issue 4), Ovid MEDLINE, Ovid MEDLINE In-Process and Other Non-Indexed Citations, Ovid MEDLINE Daily, Ovid OLDMEDLINE (January 1946 to May 2016), EMBASE (January 1980 to May 2016), Latin American and Caribbean Health Sciences Literature Database (LILACS) (January 1982 to May 2016), System for Information on Grey Literature in Europe (OpenGrey) (January 1995 to May 2016), the ISRCTN registry (www.isrctn.com/editAdvancedSearch), ClinicalTrials.gov (www.clinicaltrials.gov) and the World Health Organization (WHO) International Clinical Trials Registry Platform (ICTRP) (www.who.int/ictrp/search/en). We did not use any date or language restrictions in the electronic searches for trials. We last searched the electronic databases on 9 May 2016. We also searched the reference lists of included studies, unpublished 'grey' literature and conference proceedings and contacted pharmaceutical companies for details of unpublished trials. SELECTION CRITERIA We included randomised and quasi-randomised controlled trials that compared patching the eye with no patching to treat simple corneal abrasions. DATA COLLECTION AND ANALYSIS Two authors independently assessed the risk of bias and extracted data. Investigators were contacted for further information regarding the quality of trials. The primary outcome was healing at 24, 48 and 72 hours while secondary outcomes included measures of pain, quality of life and adverse effects. We graded the certainty of the evidence using GRADE. MAIN RESULTS We included 12 trials which randomised a total of 1080 participants in the review. Four trials were conducted in the United Kingdom, another four in the United States of America, two in Canada, one in Brazil and one in Switzerland. Seven trials were at high risk of bias in one or more domains and one trial was judged to be low risk of bias in all domains. The rest were a combination of low risk or unclear.People receiving a patch may be less likely to have a healed corneal abrasion after 24 hours compared to those not receiving a patch (risk ratio (RR) 0.89, 95% confidence interval (CI) 0.79 to 1.00, 7 trials, 531 participants, low certainty evidence). Similar numbers of people in the patch and no-patch groups were healed by 48 hours (RR 0.97, 95% CI 0.91 to 1.02, 6 trials, 497 participants, moderate certainty evidence) and 72 hours (RR 1.01, 95% CI 0.97 to 1.05, 4 trials, 430 participants, moderate certainty evidence). Participants receiving a patch took slightly longer to heal but the difference was small and probably unimportant (mean difference (MD) 0.14 days longer, 95% CI 0 to 0.27 days longer, 6 trials, 642 participants, moderate certainty evidence).Ten trials reported pain scores. Most studies reported pain on a visual analogue scale (VAS). It was not possible to pool the data because it was skewed. In general, similar pain ratings were seen between patch and no-patch groups. Data from two trials reporting presence or absence of pain at 24 hours was inconclusive. There was a higher risk of reported pain in the patch group but wide confidence intervals compatible with higher or lower risk of pain (RR 1.51, 95% CI 0.86 to 2.65, 2 trials, 193 participants, low certainty evidence). Five trials compared analgesic use between the patch and no-patch groups. Data from three of these trials could be combined and suggested similar analgesic use in the patch and no-patch groups but with some uncertainty (RR 0.95, 95% CI 0.69 to 1.32, 256 participants, low certainty evidence). Frequently reported symptoms included photophobia, lacrimation, foreign body sensation and blurred vision but there was little evidence to suggest any difference in these symptoms in people with or without a patch.Activities of daily living (ADL) were assessed in one study involving children. There was little difference in ADL with the exception of walking which was reported to be more difficult with a patch on: VAS 1.7 cm (SD 2.1) versus 0.3 cm (SD 0.7).Complication rates were low across studies and there is uncertainty about the relative effects of patching or not patching with respect to these (RR 3.24, 95% CI 0.87 to 12.05, 8 trials, 660 participants, low certainty evidence). Three trials reporting rates of compliance to treatment found that 22% of participants did not have their eye patches during follow-up. No-patch groups generally received more adjuvant treatment with antibiotics or cycloplegics, or both, than the patch group. There were limited data on the effect of patching on abrasions greater than 10mm(2) in size. AUTHORS' CONCLUSIONS Trials included in this review suggest that treating simple corneal abrasions with a patch may not improve healing or reduce pain. It must be noted that, in these trials, participants who did not receive a patch were more likely to receive additional treatment, for example with antibiotics. Overall we judged the certainty of evidence to be moderate to low. Further research should focus on designing and implementing better quality trials and examining the effectiveness of patching for large abrasions.

Abstract
ABSTRACT:Objectives:Our objective was to determine the practice patterns of Canadian emergency physicians with respect to the management of traumatic corneal abrasions.Methods:After developing our instrument and pilot testing it on a sample of emergency residents, we randomly surveyed 470 members of the Canadian Association of Emergency Physicians, using a modified Dillman technique. We distributed a pre-notification letter, an 18-item survey, and appropriate follow-up surveys to non-responders. Those members with an email address (n= 400) received a Web-based survey, and those without (n= 70) received a survey by post. The survey focused on the indications and utilization of analgesics (oral and topical), cycloplegics, eye patches and topical antibiotics.Results:Our response rate was 64% (301/470), and the median age of respondents was 38 years. Most (77.7%) were male, 71.8% were full-time emergency physicians, 76.5% were emergency medicine certified, and 64.4% practised in teaching hospitals. Pain management preferences (offered usually or always) included oral analgesics (82.1%), cycloplegics (65.1%) and topical nonsteroidal anti-inflammatory drugs (NSAIDs) (52.8%). Only 21.6% of respondents performed patching, and most (71.2%) prescribed topical antibiotics, particularly for contact lens wearers and patients with ocular foreign bodies. Two-thirds of the respondents provided tetanus toxoid if a foreign body was present, and 46.2% did so even if a foreign body was not present. Most respondents (88.0%) routinely arranged follow-up.Conclusions:This national survey of emergency physicians demonstrates a lack of consensus on the management of traumatic corneal abrasions. Further study is indicated to determine the optimal treatment, particularly regarding the use of topical NSAIDs.

Abstract
PURPOSE Corneal erosion is common in eye emergency cases. Extensive corneal erosions result in severe pain and prolonged healing time. This study aimed to compare bandage contact lenses with pressure patching in terms of reducing the size of the erosion area, pain scale in patients with corneal erosion and its complications. DESIGN A randomized open-label clinical trial was conducted. METHODS Subjects with mechanical corneal erosion were selected to use either bandage contact lenses or pressure patching. All subjects received antibiotic eye drops and 0.5% tropicamide eye drops. Evaluations were done 24 and 72 hours after treatment. The size of the corneal erosion area, pain scale, and complications were assessed. RESULTS A total of 32 eyes (16 eyes in each group) were studied. The change in the size of the corneal erosion area was greater in the bandage contact lens group than in the pressure patching group, although there was no significant difference. In the bandage contact lens group, 56.25% of the eyes were healed at 24 hours and 43.75% were healed at 72 hours. In the pressure patching group, 62.50% were healed at 24 hours and 12.50% were healed at 72 hours. The change in pain scale was significantly greater in the bandage contact lens group than in the pressure patching group. No complications were found in both groups. CONCLUSIONS Bandage contact lenses are an effective alternative to treating mechanical corneal erosion because of their effect in reducing pain without causing any complications.

Abstract
PURPOSE Fingernail-induced corneal abrasions are one of the most common eye injuries that present to the emergency department, and yet there is little literature available to offer guidelines for management. We analyzed the treatment used in cases of fingernail-induced corneal abrasions that presented to the Massachusetts Eye and Ear Infirmary Emergency Department and studied its relationship to the development of complications such as recurrent erosion syndrome and infection. METHODS We performed a retrospective review of 99 patients who presented to the Massachusetts Eye and Ear Infirmary Emergency Department with fingernail-induced corneal abrasions between January 1, 2009 and December 31, 2009. We followed the patients for 12 months and documented demographics, nature of the injury, treatment, and complications. RESULTS The average age was 29.4 (range, 2-89) years. Forty-four percent (n = 44) were female and 56% (n = 55) were male. Of the 99 subjects, 39 had a full 12 month follow-up, and 7 developed a complication from the injury. Compared with the 32 subjects without complications, there was no difference in age or gender. However, there was a significant difference in that adults scratched by another adult were more highly represented in the group with complications (43%, n = 3/7 vs. 3%, n = 1/32; P = 0.0017). There was no significant difference in outcome by treatment used. CONCLUSIONS This is the largest fingernail-induced corneal abrasion study completed to date. Patients are at risk of developing complications, but there is scant evidenced-based literature available for treating this common injury. Prospective trials should be performed to better optimize and standardize treatments.

Abstract
PURPOSE The purpose of this study was to evaluate the need for close follow-up after removal of noncomplicated corneal foreign bodies. METHODS This is an observational prospective cohort study of 60 eyes in noncontact lens wearers with corneal foreign bodies outside the visual axis. Foreign bodies were removed and patients were followed as per the Wills Eye Manual guideline for 1 to 3 days after foreign body extraction, and every 3 to 5 days until resolution of the epithelial defect. Patients were asked to record their symptoms of eye pain, eye irritation, eye redness, and visual acuity on a visual analog scale to monitor symptoms related to development of infectious keratitis. The primary endpoint was resolution of the epithelial defect. RESULTS The average time to resolution of the epithelial defect was 4.34 ± 1.56 days, with an average of 2.2 ± 1.23 follow-up visits after removal. One patient developed infectious keratitis (1.67%). Symptoms showed a statistically significant improvement in patients who had healed epithelial defects, and a statistically significant worsening in the 1 patient who developed infectious keratitis (sensitivity = 1 and specificity = 0.915). CONCLUSIONS Few noncomplicated injuries develop infectious keratitis. We recommend fewer follow-ups for these injuries. However, if patients develop any worsening in eye pain, irritation, redness, or decrease in their visual acuity, they should return promptly for reassessment.

Abstract
Corneal abrasions result from a superficial lesion to the most anterior aspect of the eye, the corneal epithelium. Patients can present to the GP with an array of symptoms including pain, foreign body sensation, decreased visual acuity/blurring, epiphora (excess watering) and photophobia. Most corneal abrasions are self-limiting and appropriate management can be instituted in the GP surgery. However, some require referral for specialist ophthalmology assessment. This article looks at the assessment and management of corneal abrasions and provides evidence-based guidance for ophthalmology referral.

Abstract
PRACTICAL RELEVANCE Feline hypertrophic cardiomyopathy (HCM) is the most common cardiac disease of cats. Treatment of HCM is usually directed at controlling signs of congestive heart failure (CHF), preventing occurrence or recurrence of systemic thromboembolism or delaying/preventing/reversing progression of subclinical disease. STUDY OBJECTIVE AND DESIGN Despite the laudable goals of therapy, however, little objective evidence supporting therapeutic decisions has been published. We, therefore, hypothesized that cardiologists base their treatment strategies on information other than published clinically relevant science. To gain insight into therapeutic decisions that cardiologists and clinicians with an interest in cardiology (n=99) make for cats with HCM, and on what information they base these decisions, we presented participants with, and asked them to select therapy for, 12 hypothetical scenarios of HCM (± CHF). Responses and justifications for treatment choices were compiled and compared with the results of a comprehensive literature search for published information about treatment of feline HCM. FINDINGS Evaluation of the therapeutic strategies chosen for these hypothetical cases of HCM suggests that cardiologists or clinicians with a strong interest in cardiology often prescribe treatments knowing that little documented evidence supports their decisions.

Abstract
OBJECTIVES We sought to determine the prevalence of corneal abrasions and possible associations with fingernail length, demographic information, sleeping, and crying among young infants. METHODS Parents of 1- to 12-week-old infants without symptoms who were presenting for well-child visits completed a brief questionnaire on age, gender, race, fingernail-trimming practices, and sleeping and crying in the preceding 24-hour period. Fingernail length was measured, and eyes were examined through staining with fluorescein and illumination/magnification with a Bluminator (Eidolon Optical, Natick, MA). Patients with corneal abrasions were given orally administered acetaminophen and erythromycin ointment. Masked interrater reliability for abrasions was measured. Logistic regression analyses determined the association of corneal abrasions with potential covariates. RESULTS Ninety-six subjects were enrolled, including 47 girls (49%), with a mean age of 32.2 days (SD: 21.7 days). Forty-seven infants (49%) had abrasions. Demographic variables and mean crying times (114.8 +/- 124.9 vs 86.5 +/- 111.7 minutes; P < .24) were not significantly different for infants with and without abrasions. Infants with abrasions slept more (15.9 +/- 3.3 vs 14.5 +/- 3.6 hours; P = .054). Associations of fingernail-trimming method and fingernail length with corneal abrasions were not statistically significant. Masked interrater reliability was high, with agreement between the primary investigator and the associate investigator for 20 (91%) of 22 eyes and agreement between the primary investigator and a pediatric ophthalmologist for 9 (90%) of 10 eyes. CONCLUSIONS Corneal abrasions are extremely common among 1- to 12-week-old infants and have unclear clinical significance. Primary care physicians should be careful about attributing unexplained persistent crying to corneal abrasions, potentially missing a more-serious problem.

Abstract
While usually considered in conjunction with obvious ophthalmic trauma, ocular foreign bodies can also present subtly. Early identification of this common complaint is crucial to preserve optimal ocular function, minimize morbidity and reduce discomfort in patients. We review a systemic approach to both the identification and management of foreign bodies in the eye.

Abstract
Chemical or radiant energy injuries to the eyes are considered ocular burns. The majority of these injuries are occupation-related. Chemical burns are by far more common and represent a true emergency. Thermal and UV injuries are associated with severe pain, but often result in less long-term sequelae than chemical injuries do. The term "biologic exposure" refers to an exposure to human blood or other body fluid. This article describes patterns of these injuries and exposures, with particular emphasis on emergent management and including acute diagnostic and treatment considerations.

Abstract
BACKGROUND Recent audits show that corneal abrasion is a common presenting eye complaint. Eye patches are often recommended for treating corneal abrasions despite the lack of evidence for their use. This systematic review was conducted to determine the effects of the eye patch when used to treat corneal abrasions. OBJECTIVES The objective of this review was to test the hypothesis that patching an eye following a corneal abrasion improves healing or provides pain relief. SEARCH STRATEGY We searched the Cochrane Central Register of Controlled Trials (CENTRAL) (which contains the Cochrane Eyes and Vision Group Trials Register) on The Cochrane Library (2005, Issue 2), MEDLINE (1966 to April 2005), EMBASE (1980 to April 2005), LILACS (13 April 2005), NRR (2005, Issue 2) and SIGLE (December 2004). There were no language or date restrictions in the searches. We also searched the reference lists of included studies, unpublished 'grey' literature and conference proceedings and contacted pharmaceutical companies for details of unpublished trials. SELECTION CRITERIA We included randomised and quasi-randomised controlled trials that compared patching the eye with no patching to treat simple corneal abrasions. DATA COLLECTION AND ANALYSIS Two authors independently assessed trial quality and extracted data. We contacted investigators for further information regarding quality of trials. The primary outcome was healing of the corneal epithelium and secondary outcomes were related to pain. MAIN RESULTS Eleven trials, which randomised a total of 1014 participants, were included in the review. Meta-analysis of seven studies with dichotomous healing outcomes favoured no patching on the first day of healing (risk ratio (RR) 0.89, 95% Confidence Interval (CI) 0.79 to 0.99). For days two and three there was no significant difference between the two groups. Of the nine trials that measured pain scores two favoured no patching and none favoured patching. Complication rates were low and no differences were noted in these between the two groups. No-patch groups generally received more adjuvant treatment with antibiotics and/or cycloplegics than the patch group which is an important confounding factor. AUTHORS' CONCLUSIONS Treating simple corneal abrasions with a patch does not improve healing rates on the first day post-injury and does not reduce pain. In addition, use of patches results in a loss of binocular vision. Therefore it is recommended that patches should not be used for simple corneal abrasions. Further research should focus on large (greater than 10 mm(2)) abrasions.
