RESUMO
BACKGROUND: This study aimed to report a case of neurotrophic keratitis caused by lightning. CASE PRESENTATION: A 38-year-old man was hit by lightning and suffered eye injury. He eventually developed neurotrophic keratitis. RESULTS: The patient's injury history and burn site were analyzed, and it was judged that lightning directly damaged his cornea, eventually resulting in neurotrophic keratitis. Fortunately, the patient's vision improved after treatment. CONCLUSION: Lightning can cause eye damage, and the clinical manifestations are diverse. Lightning currents cause corneal nerve loss, resulting in neurotrophic keratitis. To maintain corneal integrity and prevent disease progression, early assessment and appropriate treatment are necessary.

PURPOSE: To evaluate the prevalence and clinical characteristics of neurotrophic keratopathy (NK) in northeastern Mexico. METHODS: Retrospective cross-sectional study in which NK patients admitted to our ophthalmology clinic between 2015 and 2021 were consecutively enrolled. Data regarding demographics, clinical characteristics, and comorbidities were collected at the time diagnosis of NK was made. RESULTS: In the period from 2015 to 2021, a total of 74,056 patients were treated and of these 42 had a diagnosis of neurotrophic keratitis. The prevalence found was 5.67 [CI95 3.95-7.38] in 10,000 cases. The mean age observed was 59 ± 17.21 years occurring more frequently in males in 59% and with corneal epithelial defects in 66.7%. The most frequent antecedents were the use of topical medications in 90%, the presence of diabetes mellitus 2 in 40.5% and systemic arterial hypertension in 26.2%. A higher proportion of male patients with corneal alterations and a higher proportion of female patients with corneal ulcerations and/or perforation were observed. CONCLUSION: Neurotrophic keratitis is an underdiagnosed disease with a broad clinical spectrum. The antecedents that were contracted corroborate what was reported in the literature as risk factors. The prevalence of the disease in this geographical area was not reported, so it is expected to increase over time when searching for it intentionally.

PURPOSE: To analyse and quantify ocular surface parameters in patients with unilateral neurotrophic keratitis (NK) induced by trigeminal nerve injury post-neurosurgery. METHODS: The study included 26 unilateral NK patients who had undergone neurosurgery, and 20 matched normal controls. Demographic and clinical characteristics of all participants were collected and analysed. Slit-lamp examination, Cochet-Bonnet aesthesiometry, Keratograph 5 M, and LipiView interferometer were performed on both eyes of 17 mild NK patients. For nine moderate/severe NK patients, sub-basal nerve density was measured by in vivo confocal microscopy. RESULTS: Of the 26 patients, nine had acoustic neuroma, nine had trigeminal neuralgia, and eight had neoplasms. Facial nerve paralysis was observed in one of the 17 mild NK eyes (5.9%) and seven of the nine moderate/severe NK eyes (77.8%). Compared to contralateral and normal control eyes, 26 NK eyes showed significantly reduced sensitivity in five corneal regions (P < 0.05). Corneal sensitivity in moderate/severe NK eyes was significantly lower than in mild NK eyes (P < 0.05). Moderate/severe NK eyes had poor visual acuity, and their sub-basal nerve density was lower than that of the controls. The onset of the moderate/severe NK was from 0.5 to 24 months (median [Q1, Q3], 1 [0.5, 2.5] months) after neurosurgery. For the mild NK eyes, the number of total blinks, the first non-invasive tear breakup time (NITBUT) and average NITBUT were significantly lower than contralateral and normal control eyes (P < 0.05), and the number of partial blinks and partial blinking rate were significantly higher than the other two control groups (P < 0.05). CONCLUSIONS: Patients with NK induced by trigeminal nerve injury following neurosurgery had decreased corneal sensitivity to various degrees accompanied by increased partial blinks and shortened NITBUT. The severity of NK is related to the severity of the corneal sensory impairment. Facial nerve paralysis can worsen the clinical progression of NK.

PURPOSE: To describe the characteristics of neurotrophic keratopathy (NK) in the United States. DESIGN: Retrospective database study. PARTICIPANTS: Thirty-one thousand nine hundred fifteen eyes of 27 483 patients with a diagnosis of NK. METHODS: Retrospective analysis of visits associated with a diagnosis of NK between 2013 and 2018 using the American Academy of Ophthalmology Intelligent Research in Sight (IRIS®) Registry. MAIN OUTCOME MEASURES: Demographic information, prevalence, visual acuity (VA), concomitant diagnosis and procedure codes, and risk factors impacting VA most closely after NK onset date. RESULTS: Mean ± standard deviation (SD) age at initial diagnosis of NK was 68.0 ± 16.0 years, and 58.91% of patients were women (P < 0.0001). Presentation was unilateral in 58.14%, bilateral in 16.13%, and unspecified in 25.73%. Average 6-year prevalence of NK in the IRIS Registry was 21.34 cases per 100 000 patients. Mean ± SD VA was 0.60 ± 0.79 logMAR before diagnosis and 0.88 ± 0.94 logMAR after diagnosis (P < 0.0001). Most common concomitant diagnoses included herpetic keratitis (33.70%), diabetes (31.59%), and corneal dystrophy (14.28%). Common procedures for NK management included the use of amniotic membrane (29.90%), punctal plugs (29.65%), and bandage contact lenses (22.67%). Age, male sex, Black race, Hispanic or Latino ethnicity, unilateral involvement, concomitant diagnoses of diabetes, corneal transplantation, and herpetic keratitis were associated significantly with worse VA. CONCLUSIONS: Based on the IRIS Registry, the prevalence of NK is 21.34 cases per 100 000 patients. Visual acuity was significantly worse after NK diagnosis compared with other time points. Neurotrophic keratopathy was associated most commonly with herpetic keratitis and diabetes. Worse VA in patients with NK was associated with several demographic characteristics, history of diabetes, corneal transplantation, and herpetic keratitis.

PURPOSE: Neurotrophic keratopathy (NK) is a degenerative corneal disease caused by damage of trigeminal innervation. The purpose of this study is to evaluate the clinical outcomes and patient-reported satisfaction of treatment with amniotic membrane transplantation (AMT) or cenegermin eye drops in patients with NK. METHODS: Clinical charts of patients with NK treated with AMT (group A) or cenegermin eye drops (group B), with at least 12 months of follow-up, were reviewed for demographics, medical history, corneal healing, and disease recurrence. Patient satisfaction was evaluated by a newly developed questionnaire investigating patient's appreciation of treatment of NK (2 items) and satisfaction with NK treatment outcomes (5 items). RESULTS: At the end of treatment, complete corneal healing was observed in 13/15 (86%) patients in group A and in 23/24 (96%) in group B. At 12 months follow-up, 6/13 patients (46%) in group A and 3/23 patients (13%) in group B showed recurrence of NK (p = 0.037). Survival analysis showed that group B remained recurrence free for a significantly longer period of time than the group A (p = 0.028). Patients in group B showed a significantly higher satisfaction when compared with patients in group A (total score: 65.7 ± 15.7 vs 47.4 ± 12.8, p = 0.003), both in terms of patients' appreciation of treatment (78.3 ± 15.9 vs 52.2 ± 30, p = 0.020) and satisfaction with treatment outcomes (60.7 ± 21 vs 45.4 ± 13.3, p = 0.037). CONCLUSIONS: Treatment of NK with cenegermin was associated with long-term maintenance of corneal integrity and a higher degree of patient satisfaction.

Neurotrophins are a family of closely related secreted proteins that promote differentiation, development, and survival of neurons, which include nerve growth factor (NGF), brain-derived neurotrophic factor, neurotrophin-3, and neurotrophin-4. All neurotrophins signal through tropomyosin receptor kinases (TrkA, TrkB, and TrkC) which are more selective to NGF, brain-derived neurotrophic factor, and neurotrophin-3, respectively. NGF is the most studied neurotrophin in the ocular surface and a human recombinant NGF has reached clinics, having been approved to treat neurotrophic keratitis. Brain-derived neurotrophic factor, neurotrophin-3, and neurotrophin-4 are less studied neurotrophins in the ocular surface, even though brain-derived neurotrophic factor is well characterized in glaucoma, retina, and neuroscience. Recently, neurotrophin analogs with panTrk activity and TrkC selectivity have shown promise as novel drugs for treating dry eye disease. In this review, we discuss the biology of the neurotrophin family, its role in corneal homeostasis, and its use in treating ocular surface diseases. There is an unmet need to investigate parenteral neurotrophins and its analogs that activate TrkB and TrkC selectively.

Neurotrophic keratitis is a rare degenerative disease of the cornea that can lead to corneal ulceration, scarring, and significant visual impairment. It most commonly occurs in adults and is rarely diagnosed in children. Congenital corneal anesthesia is an extremely rare condition that requires appropriate ophthalmologists' attention in making diagnosis and treatment decisions. This condition usually presents in infancy or early childhood and is characterized by rare blinking rate, decreased tearing or a corneal ulcer that is unresponsive to treatment. In this case report, we describe a patient with multiple systemic and neurological disorders who presented to the ophthalmology department due to corneal erosion unresponsive to treatment. Brain magnetic resonance imaging confirmed bilateral trigeminal hypoplasia and the diagnosis of neurotrophic keratopathy due to bilateral congenital corneal anesthesia was made. The discrepancy between clinical signs and symptoms or treatment non-response in cases of corneal erosions should alert the ophthalmologists to suspect trigeminal dysfunction. MRI is the gold standard to confirm congenital corneal anesthesia and to differentiate from other possible neurotrophic keratitis causes.

Clinical manifestations of the new coronavirus infection can vary greatly and affect different organs and systems. Despite the lack of convincing data on the possible direct damage to the structures of the eyeball by the SARS-CoV-2 virus, indirect involvement of the organ of vision both in the acute period of the disease, during the period of convalescence, and as a part of the post-COVID syndrome is common in clinical practice. The condition of the ocular surface is not given much attention during the treatment of the main disease, especially in severe cases, which can lead to serious complications and visual acuity loss after recovery. Timely measures can prevent the loss of visual acuity. This article presents a description and discusses a rare case of multiple neuropathy of the cranial nerves associated with COVID-19, with bilateral involvement of the olfactory (I), trigeminal (V), facial (VII) and sublingual (XII) nerves, as well as the right optic nerve (II), which required staged rehabilitation.

The corneal epithelium serves as a physical barrier and a refractive element. Therefore, diseases of the corneal epithelium can increase the risk for infection and causes vision loss. The corneal epithelium can be affected by a multitude of conditions, such as infections, hereditary diseases, depositions, trauma, autoimmune conditions, factitious disorders, and iatrogenic causes. Non-infectious and non-hereditary corneal epithelial diseases represent a collection of conditions with diverse etiologies and clinical presentations but similar patient symptoms. The differing therapeutic interventions for each condition make clinical distinction important. The clinical characteristics, disease course, pathophysiology and current treatments for non-infectious, non-hereditary corneal epithelial diseases are reviewed.

INTRODUCTION: Dry Eye Disease (DED) is defined as a multifactorial disease of the ocular surface characterized by a loss of homeostasis of the tear film, and a vicious cycle of inflammation on the ocular surface. Despite its high prevalence and standing as one of the most common eye conditions seen by practitioners, the current treatment options available to patients have not proven adequate. AREAS COVERED: This review will discuss the burden of DED, its pathophysiology, as well as emerging therapies. These therapies include immunosuppressants, immunomodulators, anti-inflammatory drugs, and corticosteroids. The mechanisms of these drugs will be discussed, as well as their phase of development and results from recent clinical trials. The literature search was performed using PubMed, Cochrane Library, Web of Science, ClinicalTrials.gov, and the Springer AdisInsight database. EXPERT OPINION: The optimal therapy for DED is associated with improved bioavailability, minimal ocular side effects, and effective dosing. The ideal treatment has not yet been established, but this paper outlines a number of promising therapies. Continued development of therapies targeting the inflammation cascade, as well as the establishment of objective markers to quantify DED severity, are important aspects in the progression of treatment.

BACKGROUND: Autoimmune polyglandular syndrome type 1 (APS-1) is a rare autosomal recessive disease. In patients with APS-1, the most frequently reported ocular manifestations are keratoconjunctivitis with dry eye and retinal degeneration. However, to our knowledge, no research studies have reported the relationship between APS-1 and neurotrophic keratitis (NK). Possible explanations such as limbus cell deficiency being the primary cause of APS-1 keratopathy are not applicable to our unusual case of the patient with APS-1 presenting as ocular surface disease with NK. Our case findings suggest a new explanation for the observed corneal pathology and a potential treatment for these patients. CASE PRESENTATION: A 27-year-old woman was referred to our hospital because of intermittent blurred vision and recalcitrant ocular surface problems in both eyes for many years. She has a history of autoimmune polyglandular syndrome type 1 (APS-1), which includes hypothyroidism, hypoparathyroidism, hypoadrenalism, and hypogonadotropic hypogonadism. In vivo confocal microscopy clearly demonstrated significant degeneration of the sub-basal nerve plexus and stromal nerve bundles in her corneas bilaterally. She was diagnosed with severe NK and ocular surface disease caused by dry eye. Treatment included the application of therapeutic soft contact lenses and punctual occlusion; however, both treatments had a limited effect. CONCLUSION: Patients with APS-1 may have ocular surface disease and severe damage to corneal nerves. Regular follow-up and treatment focusing on the regeneration of corneal nerves is particularly important in these patients.

PURPOSE: To evaluate the role of tarsorrhaphy and its effectiveness in the treatment of patients with thyroid eye disease (TED). MATERIAL AND METHODS: The study identified the patients who required tarsorrhaphy for corneal lesions associated with TED among the total number of 457 patients who underwent tarsorrhaphy at the Research Institute of Eye Diseases over the past 20 years. RESULTS: Overall, 477 tarsorrhaphy surgeries (457 patients) were performed, including temporary and permanent, partial and complete. The corneal involvement in TED was the indication for tarsorrhaphy in 81 patients (101 tarsorrhaphies). TED patients were divided depending on the date of operation, and it was found that 61 tarsorrhaphies were performed in the period from 2000 to 2009, and 40 similar interventions were performed in the period from 2010 to 2019. CONCLUSION: The reduction in the number of tarsorrhaphy surgeries in patients with TED in the last decade due to improvement of techniques for bony decompression of the orbit and increase in the number of these operations allowed significant reduction of the degree of proptosis and, as a consequence, the exposure surface area of the eye. However, despite all the successes achieved in orbital surgery, tarsorrhaphy still remains an affordable technique that can always be used in case of corneal lesions in thyroid eye disease.

BACKGROUND: Healthy corneal epithelium acts as a barrier against damage to the deeper structures in the eye. Failure in the mechanisms of corneal epithelization can lead to persistent epithelial defects of the cornea (PEDs) and can compromise its function. Epidermal growth factor (EGF) promotes the proliferation, migration, and differentiation of epithelial cells, endothelial cells, and fibroblasts during wound healing and may be beneficial in treating patients with PEDs. We, therefore, investigated the effect of EGF ointment on patients with PEDs. METHODS: Fifteen patients with PEDs refractory to conventional treatment were treated twice a day with EGF ointment. Patient demographics and comorbidities were noted. The epithelial healing time was determined along with the primary outcome measures in the areas of the epithelial defects, visual acuity, visual analog scale (VAS) scores, and esthesiometer scores 1 month and 2 months after treatment. RESULTS: Five eyes of herpetic keratitis (33.3%), 3 eyes of dry eye disease (20.0%), 3 eyes of bacterial keratitis (20.0%), 2 eyes of limbal stem cell deficiency (13.3%), 1 eye of diabetic neurotrophic keratitis (6.7%), and 1 eye of filamentary keratitis (6.7%) were associated with PEDs, respectively. Two months following treatment with EGF ointment, there was a reduction in the area of the epithelial defects (5.7 ± 3.9 to 0.1 ± 0.3 mm2) as well as a significant improvement in best-corrected visual acuity (0.9 ± 0.8 to 0.6 ± 0.5 LogMAR) and VAS scores (4.5 ± 1.2 to 2.5 ± 0.7) in 12 eyes (80%). Among these cases, the mean epithelial healing time was 5.5 ± 1.8 weeks. Amniotic membrane transplantation was performed on the remaining 3 (20.0%) patients that did not respond to EGF treatment. CONCLUSIONS: EGF ointment could reduce symptoms and promotes corneal epithelialization of refractory PEDs. It may, therefore, be well-tolerated and a potentially beneficial addition in the management of refractory PEDs.

In this report, we analyse the pre- and post-operative corneal changes observed using in vivo confocal corneal microscopy in a patient with neurotrophic keratitis submitted to a corneal reinnervation surgical procedure. We describe favourable trophic changes observed at different levels of the patient's cornea, particularly in the sub-basal nerve plexus; complete absence of these neurological structures was observed before surgery, but appeared largely restored six months thereafter.
RESUMO
A 47-year-old man with Wallenberg syndrome after a stroke in the territory of the left vertebrobasilar artery and posterior inferior cerebellar artery, presented a week later complaining of visual loss in the left eye. Examination showed corneal anaesthesia associated with a neurotrophic corneal epithelial defect. Corneal involvement secondary to trigeminal neuropathy in Wallenberg syndrome is not frequently reported and may lead to epithelial erosion and neurotrophic keratopathy. Clinicians should be aware that visual loss can occur from a neurogenic basis (e.g., Wallenberg syndrome) due to neurotrophic keratopathy. The use of cocaine, a potential cause of neurotrophic keratopathy, should also be suspected in the appropriate clinical scenario.
RESUMO
Objective: To investigate the clinical characteristics and therapeutic effect of neurotrophic keratitis (NK). Methods: A retrospective case series study. A total of 46 patients (48 eyes) with clinically diagnosed NK in Beijing Tongren Hospital from May 2013 to July 2016 were analyzed, including 26 males (26 eyes) and 20 females (22 eyes), aged (51±18) years. The general condition, etiology, clinical features, stage of disease and curative effect of NK patients were summarized. Corneal sensation was measured by Cochet-Bonnet corneal sensor for 25 patients (26 eyes), and the correlation between corneal sensation and clinical staging was analyzed. The χ(2) test was performed on the distribution characteristics of patients with different clinical stages of NK. Correlation analysis of corneal sensation and the disease stage was performed using Spearman correlation analysis. Results: Forty-four cases of monocular disease (96.65%) and 2 cases (4.35%) of bilateral disease were enrolled. Four eyes (8.33%) were from young patients (aged 18-29 years), 23 (47.92%) were from middle-aged patients (aged 30-59 years), and 21 (43.75%) were from elderly patients (aged ≥60 years). The disease was at stage â in 8 eyes (16.67%), at stage â ¡ in 21 eyes (43.75%), and stage â ¢ in 19 eyes (39.58%). There was no significant difference in clinical staging between the three age groups (χ(2)=2.452, P=0.658). The most common cause of NK was virus infection (17 eyes,35.42%), followed by neurosurgical sequelae (11 eyes, 22.92%) and diabetes in 10 eyes(20.83%). Corneal sensation of 26 eyes ranged from 0-3 cm. There was no significant correlation between clinical stage and corneal sensation (r(2)=0.284, P=0.753). The patients were followed up for an average of 7 months. Thirty-four eyes (70.83%) received conservative treatment, and 8 eyes(16.67%) had surgery. Six patients (6 eyes) were lost for follow-up. Conclusions: NK can occur in all ages, mainly in the elderly. The clinical manifestations are diverse. If time delays in the diagnosis and treatment, it often causes corneal ulcers. There is no significant correlation between corneal sensation and clinical stage. Early diagnosis and targeted treatment are important for protecting patients' visual function.(Chin J Ophthalmol, 2020, 56:274-298).

Combined lesions of the facial and trigeminal cranial nerves are typical after neurosurgical treatment. Violation of the innervation of orbicularis muscle leads to inability to completely close the eyelids, while denervation of the cornea is often manifested as a long-term ongoing and recurring neurotrophic keratitis. The restoration of corneal innervation is a pathogenetically targeted treatment for this pathology. For this purpose, neurotrophic keratitis could be reversed via the method of corneal neurotization using contralateral n. ophthalmicus. The presented clinical case demonstrates the results of the first operation of neurotization of the cornea in a patient with combined lesions of the facial and trigeminal nerves.

PURPOSE: To develop a method for treatment of advanced purulent corneal ulcers in eyes with neurotrophic keratitis that developed as a complication of intracranial pathological processes or brain surgeries. MATERIAL AND METHODS: The study involved 13 patients (14 eyes) that underwent combined surgery - keratoplasty, autoconjunctival flap covering, partial tarsorrhaphy performed simultaneously. Before and after the surgery, patients received frequent instillations of antimicrobial agents and autologous serum. RESULTS: The organ of vision was preserved in all patients, visual function - in 50% of cases, it improved in 35.7% of cases from 0.07±0.05 to 0.26±0.11. Lagophthalmos has decreased from 6.11±0.99 to 2.78±0.62 mm. CONCLUSION: Patients with intracranial lesions and complicated by neurotrophic keratitis and lagophthalmos often develop advanced severe and progressive corneal purulent ulcers, which seldom respond to the most active conservative therapy. Simultaneous surgery that includes keratoplasty, auto conjunctival flap covering and partial superficial tarsorrhaphy is an effective treatment option that helps preserve visual function in such eyes.

PURPOSE: To provide preliminary data about efficacy and safety of plasma rich in growth factors (PRGF) eye-drops in neurotrophic keratitis (NK) and to analyze the possible influence of certain variables on treatment outcomes. METHODS: This retrospective study included patients with stages 2-3 of NK treated with PRGF eye-drops. Primary endpoint was the resolution time of corneal ulcer defect. Outcome measures including percentage of ulcer closure at 4 weeks, Ocular Surface Disease Index (OSDI), Best-Corrected Visual Acuity (BCVA) and Visual Analogue Scale (VAS) were also evaluated before and after treatment with PRGF. The influence of some patients' clinical variables on results was assessed. Safety assessment was also performed reporting all adverse events. RESULTS: Thirty-eight treated eyes in a total of thirty-one patients were evaluated, of which five cases had no prior response to autologous serum treatment. Most cases (97.4%) achieved the complete resolution of corneal defect/ulcer. Mean resolution time was 11.4 weeks (SD = 13.7). A statistical significant (p < 0.05) reduction in OSDI (60.9%), VAS frequency (59.9%), VAS severity (57.0%) and improvement in BCVA (52.8%) was observed. The results were stratified according to the pathology stage and to the identified potential effect modifiers variables. Only one adverse event was reported in one patient (2.6%). CONCLUSIONS: PRGF eye-drops could be a safe and effective therapeutic option for patients with stages 2-3 of NK, showing high rates of corneal defect/ulcer resolution in short times, either in reducing signs and symptoms of NK, and therefore preventing the progression of NK to greater ocular complications.
