ABSTRACT
Oral Submucous Fibrosis is a potentially malignant disorder caused by habitual areca nut chewing, which contributes to the dispersion of active alkaloids into subepithelial tissues, stimulating excessive extracellular matrix deposition. Various treatment modalities are available; however, their efficacy in inhibiting fibrosis progression remains limited. Sulforaphane (SFN), an isothiocyanate found abundantly in cruciferous plants, is known to have effective antifibrotic properties. Objective: The present study investigated the antifibrotic effect of SFN via phosphatidylinositol 3 kinase (PI3K), Serine/Threonine Kinase 1 (AKT-1), mammalian target of rapamycin (mTOR) pathway in arecoline (AER) induced fibrosis in human gingival fibroblasts [HGFs]. Material and Methods: MTT assay determined the half-maximal inhibitory concentration of AER and SFN at 24h in the HGF cell line. Expression levels of transforming growth factor ß1 (TGFß1), collagen type 1 alpha 2 (COL1A2), hydroxyproline (HYP), PI3, AKT, mTOR, and nuclear factor erythroid 2related factor 2 (NRF2) were assessed post-AER and SFN treatment using qPCR and western blot analysis. Results: The findings of the study revealed that AER elicited a stimulatory effect, upregulating TGFß1, COL1A2, HYP, PI3K, AKT, and mTOR and downregulating NRF2 expression. Conversely, SFN treatment significantly upregulated NRF2, inhibiting TGFß1 mediated PI3/AKT/mTOR pathway. Conclusion: These observations suggest that SFN can be used as a promising synergistic antifibrotic agent to combat fibrogenesis via the non-Smad pathway (AU)
Fibrose submucosa oral é uma desordem potencialmente maligna causada pelo habito de mascar a noz da areca, o que contribui para a dispersão de alcalóides ativos nos tecidos subepiteliais, estimulando a deposição excessiva de matriz extracelular. Há várias modalidades terapêuticas, no entanto, com eficácia limitada no controle da progressão da fibrose. O sulforafano (SFN), isotiocianato encontrado abundantemente em plantas crucíferas, é conhecido por suas propriedades antifibróticas. Objetivo: Investigar os efeitos antifibróticos do SFN na via fosfatidilinositol3-quinase (PI3K), via quinase serina/treonina 1 (AKT-1), via do alvo da rapamicina em mamíferos (mTOR), na fibrose induzida por arecolina (AER) em fibroblastos gengivais de humanos (HGFs). Material e Métodos: A meia concentração inibitória mínima de AER e SFN em 24 horas nas células HGFs foi determinada por MTT. Os níveis de expressão de ß1 (TGFß1), colágeno tipo 1 alfa 2 (COL1A2), hidroxiprolina (HYP), PI3K, AKT, mTOR, fator nuclear eritroide 2 relacionado ao fator 2 (NRF2) foram analisados após tratamento com ERA e SFN através de qPCR e western blot. Resultados: O ERA apresentou efeito estimulatório aumentando a expressão de TGFß1, COL1A2, HYP, PI3K, AKT e mTOR e diminuindo a expressão de NRF2. Por outro lado, tratamento com SFN aumentou significativamente a expressão de NRF2, inibindo a liberação de TGFß1 mediada pela via PI3/AKT/mTOR. Conclusão: Esses achados sugerem que o SFN pode ser um agente antifibrótico promissor no combate à fibrogênese decorrente da via não-Smad (AU)

Objectives To study the course of West syndrome (WS) and coronavirus disease-19 (COVID-19) in children with WS who contracted SARS-CoV-2 infection. Methods This ambispective study was conducted at a tertiary-care center in North India between December 2020 and August 2021 after approval from the Institute Ethics Committee. Five children with WS, positive for COVID-19 based on RT-PCR, fulflled the inclusion criteria. Results One child with COVID-19 during the frst wave was retrospectively included while four children (of the 70 children screened) were prospectively enrolled. The median age at onset of epileptic spasms was 7 mo (2 boys), and that at presentation with COVID-19 was 18.5 mo. Three had underlying acquired structural etiology. Three were in remission following standard therapy, while two had ongoing spasms at the time of COVID-19 illness. During the illness, two of those in remission continued to be in remission while one child had a relapse. The children with ongoing epileptic spasms had variable course [one had persistent spasms and other had transient cessation lasting 3 wk from day 2 of COVID-19 illness, but electroencephalography (on day 8 of COVID-19 illness) continued to show hypsarrhythmia]. Fever was the most typical symptom (and sometimes the only symptom) of COVID-19, with a duration ranging from 1–8 d. Two children had moderate COVID-19 illness requiring hospitalization, while the rest had a mild illness. All the afected children had complete recovery from COVID-19. Conclusion The severity of COVID-19 illness in children with WS is often mild, while the subsequent course of WS is variable.
ABSTRACT
Rhino-orbito-cerebral mucormycosis (ROCM) is the most commonly noted form of mucormycosis, which is the most common secondary fungal infection following severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. Osteomyelitis is one of the rare sequelae of ROCM, frontal osteomyelitis being the rarest. We present four patients of coronavirus disease 2019 (COVID-19)-associated mucormycosis, who presented with frontal bone osteomyelitis after being treated for ROCM surgically and medically. This is the first case series highlighting this complication in post–COVID-19 mucormycosis patients and needs utmost attention as it can be life-threatening and can cause extreme facial disfiguration. All four patients are alive with salvage of the affected globe and vision being preserved in one patient. If identified early, disfiguration of face and intracranial extension can be avoided.
ABSTRACT
Objective To ascertain the efect of human immunodefciency virus (HIV) infection, as well as, antiretroviral therapy (ART) on neutrophil oxidative burst in children. Methods Fifty-fve children living with HIV infection (30 receiving ART for?2 y, 25 treatment-naïve) and 30 healthy controls, aged 18 mo–18 y, were assessed for hemogram and neutrophil oxidative burst. The treatment-naïve children were followed up and the above tests were repeated after 6 mo of ART. Results Mean (SD) serum MPO activity at 6 mo after ART [32.1 (±19.9) U/L] was comparable to that at disease onset [17.2 (±23.0) U/L], although it was signifcantly higher compared to that in children on ART?2 y [13.3 (±15.8) U/L] and controls [12.1 (±11.9) U/L]. Median fuorescence intensity (MFI) of unstimulated DHR was highest at 6 mo after ART and in the treatment-naïve group, which was signifcantly higher than in the controls, as well as, children receiving ART?2 y. Stimulation index was highest in the control group [442.4 (341.9–562.9)], which was comparable to that in children on ART?2 y [304.2 (153.2–664.8)], but was signifcantly higher than the treatment-naïve cohort [266.1 (148.2–339.4)] and children on ART for 6 mo [318.8 (154.9–395.6)]. Conclusion A hyperinfammatory state caused by an increased serum myeloperoxidase enzyme activity and increased basal neutrophil oxidative burst was seen in untreated HIV infection and during initial 6 mo of ART. ART given for?2 y normalized the impaired neutrophilic phagocytic functions.
ABSTRACT
Background: Photic sneeze reflex (PSR) also known as autosomal dominant compelling helioophthalmic outburst is a rare condition characterized by uncontrolled sneezing in response to bright light. The exact mechanism causing this is poorly understood. However, various hypotheses have been proposed. Ophthalmic examination involves exposing the patient to bright light like slit lamp, indirect ophthalmoscopy and surgical microscope, which can trigger sneezing in PSR patients. Purpose: The purpose of this video is to draw light to this rare phenomenon and its implication in ophthalmic surgery. Synopsis: A 74?year?old male patient presented with diminution of vision in left eye. On routine slit lamp and IDO examination, patient had repeated sneezing. We diagnosed him to have photic sneeze reflex. He had pseudophakic bullous keratopathy in the right eye and senile immature cataract in the left eye. Taking into consideration his one eyed status and PSR, measures were taken accordingly and cataract surgery was performed uneventfully. We describe in this video the challenges encountered with this phenomenon and approach in such cases. Highlights: In this video, we tried to give an idea about photic sneeze reflex and its theories. Also, we tried to bring out the impact of PSR on ophthalmologic practice.
ABSTRACT
Purpose: Diseases affecting the cornea are a major cause of corneal blindness globally. The pressing issue we are facing today is the lack of diagnostic devices in rural areas to diagnose these conditions. The aim of the study is to establish sensitivity and accuracy of smartphone photography using a smart eye camera (SEC) in ophthalmologic community outreach programs. Methods: In this pilot study, a prospective non?randomized comparative analysis of inter?observer variability of anterior segment imaging recorded using an SEC was performed. Consecutive 100 patients with corneal pathologies, who visited the cornea specialty outpatient clinic, were enrolled. They were examined with a conventional non?portable slit lamp by a cornea consultant, and the diagnoses were recorded. This was compared with the diagnoses made by two other consultants based on SEC videos of the anterior segment of the same 100 patients. The accuracy of SEC was accessed using sensitivity, specificity, PPV, and NPV. Kappa statistics was used to find the agreement between two consultants by using STATA 17.0 (Texas, USA). Results: There was agreement between the two consultants to diagnosing by using SEC. Above 90% agreements were found in all the diagnoses, which were statistically significant (P?value < 0.001). More than 90% sensitivity and a negative predictive value were found. Conclusion: SEC can be used successfully in the community outreach programs like field visits, eye camps, teleophthalmology, and community centers, where either a clinical setup is lacking or ophthalmologists are not available.
ABSTRACT
Ocular injuries are one of the major factors for mono-ocular blindness in adult population. Majority of mechanical ocular injuries occurs in factories. Our patient had injury with grinder blade. On examination, vision was no perception of light in right eye, corneoscleral tear along with lens and vitreous in the wound. Ocular trauma score was 1 with chances of visual recovery nil. After primary treatment, when we had taken patient under general anaesthesia, we found whole retina lying over cornea which was a rare event. We excised that tissue and tear repair was done. None of the factors which can lead to expulsive haemorrhage was observed in patient. We have seen many patients with extensive corneoscleral tear but never seen retina coming out of the wound. We recommend to use all protective equipments for workers to prevent industrial ocular injuries.
ABSTRACT
Purpose: To compare post?operative pain perception using bandage contact lens (BCL) stored at 2–8?C (Cold BCL, CL?BCL) or room temperature (23 – 25?C, RT?BCL) after photorefractive keratectomy (PRK) or corneal collagen?crosslinking (CXL) and determine status of nociception associated factors. Methods: In this prospective interventional study, 56 patients undergoing PRK for refractive correction and 100 keratoconus (KC) undergoing CXL were recruited following approval from the institutional ethics committee with informed consent. Patients undergoing bilateral PRK received RT?BCL on one eye and CL?BCL on the other. Pain was graded by Wong–Baker scoring on the first post?operative day (PoD1). Expression of transient receptor potential channels (TRPV1, TRPA1, TRPM8), calcitonin gene?related peptide (CGRP) and IL?6 was measured in cellular content from used BCLs collected on PoD1. Equal number of KC patients received RT?BCL or CL?BCL post?CXL. Pain was graded by Wong–Baker scoring on PoD1. Results: Pain scores on PoD1 were significantly (P < 0.0001) reduced in subjects receiving CL?BCL (Mean ± SD: 2.6 ± 2.1) compared to RT?BCL (6.0 ± 2.4) post?PRK. 80.4% of subjects reported reduced pain scores with CL?BCL. 19.6% reported no change or increased pain scores with CL?BCL. TRPM8 expression was significantly (P < 0.05) increased in BCL of subjects reporting reduced pain with CL?BCL compared to those who did not. Pain scores on PoD1 were significantly (P < 0.0001) reduced in subjects receiving CL?BCL (3.2 ± 2.1) compared to RT?BCL (7.2 ± 1.8) post?CXL. Conclusion: The simple approach of using a cold BCL post?operatively substantially reduced pain perception and could overcome post?operative pain?related limited acceptance of PRK/CXL.
ABSTRACT
Purpose: The purpose of this study was to identify and analyze the clinical and ocular surface risk factors influencing the progression of keratoconus (KC) using an artificial intelligence (AI) model. Methods: This was a prospective analysis in which 450 KC patients were included. We used the random forest (RF) classifier model from our previous study (which evaluated longitudinal changes in tomographic parameters to predict “progression” and “no progression”) to classify these patients. Clinical and ocular surface risk factors were determined through a questionnaire, which included presence of eye rubbing, duration of indoor activity, usage of lubricants and immunomodulator topical medications, duration of computer use, hormonal disturbances, use of hand sanitizers, immunoglobulin E (IgE), and vitamins D and B12 from blood investigations. An AI model was then built to assess whether these risk factors were linked to the future progression versus no progression of KC. The area under the curve (AUC) and other metrics were evaluated. Results: The tomographic AI model classified 322 eyes as progression and 128 eyes as no progression. Also, 76% of the cases that were classified as progression (from tomographic changes) were correctly predicted as progression and 67% of cases that were classified as no progression were predicted as no progression based on clinical risk factors at the first visit. IgE had the highest information gain, followed by presence of systemic allergies, vitamin D, and eye rubbing. The clinical risk factors AI model achieved an AUC of 0.812. Conclusion: This study demonstrated the importance of using AI for risk stratification and profiling of patients based on clinical risk factors, which could impact the progression in KC eyes and help manage them better
ABSTRACT
As the morphology of submerged leaves is variously interpreted, they are subjected to a detailed morphological, anatomical and phytochemical studies. The position of origin at the leaf base, pinnate tristichous nature of leaflets and the limited life span prove the submerged leaves to be leafy in nature. The absence of root cap and exarch protoxylem which are the typical characters of roots goes against the root-concept. The morphological similarities of young submerged floating leaves to the other submerged leaves, ultrastructural studies like cuticular combs and pore like structures as in floating leaves, phytochemical observations and molecular biological data indicate the submerged structures to be true leaves. The role of environmental factors in shaping the characters is suggested.
ABSTRACT
Purpose: Ocular surface discomfort and dry eye disease are caused by a dysfunctional tear film. The efficacy of lubricating eye drops on the human eye is known, but the compositions may show differential effects on rescuing the tear film. Mucins form a critical layer of the tear film, a reduction of which may be causative for ocular surface conditions. Therefore, it is essential to develop relevant human?derived models to test mucin production. Methods: Human corneoscleral rims were obtained from a healthy donor (n = 8) post?corneal keratoplasty and cultured in DMEM/F12 media. Hyperosmolar stress mimicking dry eye disease was induced by exposing the corneoscleral rim tissues to +200 mOsml NaCl?containing media. The corneoscleral rims were treated with polyethylene glycol–propylene glycol (PEG–PG)?based topical formulation. Gene expression analysis was performed for NFAT5, MUC5AC, and MUC16. Secreted mucins were measured by enzyme?linked immunosorbent assay (ELISA) (Elabscience, Houston, TX, USA) for MUC5AC and MUC16. Results: The corneoscleral rims responded to hyperosmolar stress by upregulating NFAT5, a marker for increased osmolarity, as observed in the case of dry eye disease. The expression of MUC5AC and MUC16 was reduced upon an increase in hyperosmotic stress. The corneoscleral rim tissues showed induction of MUC5AC and MUC16 expression upon treatment with PEG–PG topical formulation but did not show significant changes in the presence of hyperosmolar treatments. Conclusion: Our findings showed that PEG–PG?based topical formulation slightly alleviated hyperosmolar stress?induced decrease in MUC5AC and MUC16 gene expression that is encountered in DED
ABSTRACT
Purpose: To evaluate the effectiveness of vision therapy (VT) in patients with chronic presumed refractory dry eye disease (DED) and concurrent nonstrabismic binocular vision anomalies (NSBVAs). To propose an algorithmic approach to manage patients with refractory DED. Methods: Thirty?two patients with chronic (>1 year) presumed refractory DED and NSBVA were prospectively evaluated. The baseline dry eye evaluation and comprehensive orthoptic evaluation were done. VT was administered by a trained orthoptist for 2 weeks. The binocular vision (BV) parameters and percentage subjective improvement were assessed after the VT. Results: On evaluation, 12 patients (37.5%) had both DED and NSBVA, and 20 patients (62.5%) had only NSBVA. Twenty?nine patients (90.62%) showed significant improvement in BV parameters following VT. Binocular near point of accommodation (median, range) improved from 17 (8–40) to 12 (5–26) mm (P value < 0.0001), and near point of convergence (median, range) improved from 6 (3–33) to 6 (5– 14) (P value 0.004) with VT. Thirty?one patients (96.87%) reported symptomatic improvement after VT, and 62.5% of these showed more than 50% improvement in symptoms. Conclusion: The present study confirms the beneficial role of VT in the treatment of patients with DED with concurrent NSBVA. It is essential to diagnose and treat NSBVA in patients with DED to ensure complete relief of symptoms and patient satisfaction. As there is a significant overlap between symptoms of dry eye disease and that of NSBVA, a complete orthoptic evaluation is recommended in all patients presenting with refractory dry eye disease related symptoms
ABSTRACT
Purpose: To study ocular surface signs, symptoms, and tear film composition following prophylactic thermal pulsation therapy (TPT) prior to refractive surgery, and to compare these outcomes with those who underwent TPT after refractive surgery. Methods: Patients with mild?to?moderate evaporative dry eye disease (DED) and/or meibomian gland dysfunction (MGD) undergoing refractive surgery were included. Group 1 patients received TPT (LipiFlow) prior to laser?assisted in situ keratomileusis (LASIK; n = 32, 64 eyes), and Group 2 patients received TPT three months after LASIK (n = 27, 52 eyes). Ocular Surface Disease Index (OSDI) score, Schirmer’s test (ST1, ST2), Tear Breakup Time (TBUT), meibography, and tear fluid were obtained preoperatively and at three months postoperatively in Groups 1 and 2. Additional postoperative evaluation was performed three months after TPT in Group 2. Tear soluble factor profile was measured by multiplex enzyme?linked immunosorbent assay (ELISA) using flow cytometry. Results: Postoperative OSDI score was significantly lower and TBUT was significantly higher when compared with matched preoperative values of Group 1 participants. On the other hand, the postoperative OSDI score was significantly higher and TBUT significantly lower when compared with matched preoperative values of Group 2 participants. TPT significantly reduced the postoperative elevation in OSDI and significantly reduced the postoperative reduction in TBUT in Group 2 participants. Tear Matrix metalloproteinase?9/ Tissue inhibitor matrix metalloproteinase 1 (MMP?9/TIMP1) ratio was significantly higher, postoperatively, when compared with matched preoperative levels in Group 2. However, MMP9/TIMP1 ratio remained unaltered in Group 1 participants. Conclusion: TPT prior to refractive surgery improved postsurgical ocular surface signs and symptoms and reduced tear inflammatory factors, thereby suggesting the plausibility of reduced post?refractive surgery DED in patients.
ABSTRACT
With changes in lifestyle, such as the increasing use of digital screens and rising demand for refractive surgery, dry eye disease has become increasingly prevalent in recent times. While we are equipped with a number of diagnostic modalities and a myriad of treatment forms, ranging from topical medication to procedural therapies, the condition remains an enigma in terms of varied patient satisfaction. An understanding of the molecular basis of a disease may open up new avenues in the customization of its treatment. We attempt to simplify this in the form of a stepwise protocol to incorporate biomarker assays in dry eye management.
ABSTRACT
Background: Term small for gestational age (SGA) babies are at risk for developing iron deficiency anemia. The association between maternal and infant iron stores is not clear. Objective: To assess proportion of term SGA neonates developing iron deficiency anemia by 10 weeks of age, and measure correlation between iron profile and hepcidin of babies at birth and at 10 weeks of age with maternal iron profile. Design: Prospective cohort study conducted from November, 2018 to April, 2020. Participants: 120 term SGA babies and their mothers. Intervention: Hemogram, iron profile and serum hepcidin (every fourth case) estimated in mother, cord blood and baby at 10 weeks. Babies developing anemia at 6 weeks detected by hemogram and ferritin were started on iron supplementation and excluded from the study. Outcome: Proportion of babies developing iron deficiency anemia at 10 weeks of age. Results: 35 (29.2%) of 120 term SGA babies developed anemia (hemoglobin <9 g/dL) at 6 weeks. Proportion of infants who developed iron deficiency anemia (hemoglobin <9 g/dL and serum ferritin <40 µ/dL) at 6 and 10 weeks of age was 14.2% and 23.3%, respectively. No significant correlation was found bet-ween hemoglobin, iron and hepcidin of the baby in cord blood and at 10 weeks of age with that of mothers. Serum hepcidin in babies at birth (137.5 ng/mL) were higher than maternal values (128 ng/mL). Conclusion: A significant proportion of term SGA infants developed anemia during early infancy, irrespective of maternal iron status.
ABSTRACT
Purpose: To create a predictive model using artificial intelligence (AI) and assess if available data from patients’ registration records can help in predicting definitive endpoints such as the probability of patients signing up for refractive surgery. Methods: This was a retrospective analysis. Electronic health records data of 423 patients presenting to the refractive surgery department were incorporated into models using multivariable logistic regression, decision trees classifier, and random forest (RF). Mean area under the receiver operating characteristic curve (ROC?AUC), sensitivity (Se), specificity (Sp), classification accuracy, precision, recall, and F1?score were calculated for each model to evaluate performance. Results: The RF classifier provided the best output among the various models, and the top variables identified in this study by the RF classifier excluding income were insurance, time spent in the clinic, age, occupation, residence, source of referral, and so on. About 93% of the cases that did undergo refractive surgery were correctly predicted as having undergone refractive surgery. The AI model achieved an ROC?AUC of 0.945 with an Se of 88% and Sp of 92.5%. Conclusion: This study demonstrated the importance of stratification and identifying various factors using an AI model which could impact patients’ decisions while selecting a refractive surgery. Eye centers can build specialized prediction profiles across disease categories and may allow for the identification of prospective obstacles in the patient’s decision?making process, as well as strategies for dealing with them.
ABSTRACT
Introduction: Left ventricular (LV) diastolic dysfunction is common on preoperative screening among patients undergoing surgery. There is no simple screening test at present to suspect LV diastolic dysfunction. This study was aimed to test the hypothesis, whether elastic recoil signal (ERS) on tissue Doppler imaging of mitral annulus (MA TDI) can be used as a qualitative test to differentiate patients from normal LV diastolic function versus patients with LV diastolic dysfunction. Methods: This was a prospective cross-sectional observational study of patients admitted for elective surgeries. Normal diastolic function and categorization of LV diastolic dysfunction into severity grades I, II, or III were performed as per the American Society of Echocardiography/ European Associationof Cardio Vascular Imaging (ASE/EACVI) recommendations for LV diastolic dysfunction. Results: There were 41 (61%) patients with normal LV diastolic function and 26 (39%) patients with various grades of LV diastolic dysfunction. In 38 out of 41 patients with normal LV diastolic function, the characteristic ERS was identified. The ERS was absent in all the patients with any grade of LV diastolic dysfunction. Consistency of identification of ERS on echocardiography was tested with a good interobserver variability coefficient of 0.94 (P-value <0.001). The presence of ERS demonstrated an excellent differentiation to rule out any LV diastolic dysfunction with an area under the receiver operating characteristics curve (AUROC) of 0.96 (CI 0.88�99; P value <0.001). Conclusions: To conclude, in a mixed surgical population, the anesthetist could successfully assess LV diastolic dysfunction in the preoperative period and the characteristic ERS on MA TDI signal can be used as a qualitative test to differentiate patients from normal LV diastolic function versus patients with LV diastolic dysfunction using the transthoracic echocardiography (TTE).
ABSTRACT
Duchenne muscular dystrophy is one of the most common dystrophinopathies known. It is the most common hereditary neuromuscular disorder and is inherited in an X-linked recessive manner. Incidence is 1:3500 live male infants, characterised by progressive weakness of a selective group of muscles without involvement of nervous system. Age of onset being 3-10 years, many children unable to walk before 18 months of age. The patient usually dies by 18-20 years of age. 80% carries have high CPK values with female being the one. Dystrophin gene is the largest human gene with 79 exons, codes for protein dystrophin required for stabilisation of protein complex at sarcolemma, the abnormal DMD gene is on X chromosome at Xp21 locus. Dystrophin deficiency thus, leads to destruction of muscle fibres and progressive muscular weakness. Corticosteroids are the only medications that have shown to alter the course of DMD but have side effects like weight gain, decreased appetite, increase changes of cataract and osteoporosis. The present study is about management 8 years old male child with B/L lower limb weakness and calf muscle hypertrophy.etc, so according to Ayurvedic management with Panchkarma procedures and internal medicines given the case was managed. Successful improvement in CPK values along with the signs and symptoms was observed. As per Ayurvedic Siddhant and Samprapti application considering Adibalapravrittavyadhi and the Beejabhaga avayava dushti the management done. There is no treatment in any system of medicine and prognosis being unpreventable, Ayurveda instills a regenerative mechanism in neuromuscular disorders with special concern of Panchkarma, Rasayanas, Rasa aushadhi, etc. By this the deterioration can effectively be prolonged and quality of life improved.
ABSTRACT
Purpose: To evaluate the efficacy of liposomal amphotericin B (L?AMB) for the treatment of fungal keratitis. Methods: Patients with fungal keratitis confirmed by potassium hydroxide (KOH) smear and/ or confocal microscopy were administered topical L?AMB and randomized into three groups treated with three different formulations. The medication was administered two hourly till clinical improvement was achieved, followed by six hourly till complete resolution. The outcome measures were time to clinical improvement, resolution of epithelial defect, stromal infiltrate, hypopyon, extent and density of corneal opacity, neovascularization, and best corrected visual acuity (BCVA) at 3 months. Results: Mean age of the patients was 46.6 ± 14.8 years, and trauma with vegetative matter was the most common predisposing factor. Aspergillus flavus (36%) was the most common fungus cultured, followed by Fusarium (23%). Mean time to clinical improvement, time to resolution of epithelial defect, mean time to resolution of infiltrate, and time to resolution of hypopyon were 3.45 ± 1.38, 25.35 ± 8.46, 37.97 ± 9.94, and 13.33 ± 4.90 days, respectively, and they were comparable among the three groups. There was a significant difference between treatment failure and success cases in terms of days of presentation (P < 0.01), size of the epithelial defect (P?value 0.04), and infiltrate size at presentation (P?value 0.04). At 3 months follow?up, no statistically significant difference was noted in BCVA and mean scar size among groups. Conclusion: L?AMB in a gel form is an effective antifungal agent that promotes the healing of fungal ulcers with notably least vascularization and better tolerance.
