cornea photo quiz
This patient presents with dendritic lesions and terminal bulbs on their cornea. The diagnosis is herpes simplex keratitis. Differential diagnoses include herpes zoster keratitis, healing recurrent erosion, soft contact lens wear. Treatment recommended is trifluorothymidine 1% eye drops 9 times per day or alternatively 3% vidarabine ointment 5 times per day. Oral acyclovir would not benefit in preventing development of stromal keratitis.
Cataract Lec.ppt.pdf, define, objective refraction, subjective refraction
This document provides an overview of the lens and cataract. It defines a cataract as any opacity in the lens or lens capsule. The lens is normally transparent and helps refract light. Cataracts are caused by opacification, degeneration or deposition of abnormal materials in the lens. Risk factors include age, trauma, uveitis and medications like steroids. Cataracts can be classified by morphology, age of onset, maturity or etiology. Common symptoms are blurred vision, glare, halos and color changes. Treatment is usually surgical removal of the cataract and implantation of an intraocular lens. Complications may include infection, inflammation or glaucoma if left untreated.
CRANIAL ULTRASONOGRAPHY IN NEWBORN
Cranial ultrasonography (CUS) is a useful tool for screening and evaluating the neonatal brain. CUS can accurately detect intraventricular hemorrhage, cystic periventricular leukomalacia, and ventriculomegaly. It is recommended that all infants with a birth weight less than 1250 grams or gestational age less than 30 weeks receive routine CUS screening at 7-14 days of age and again at 36-40 weeks postmenstrual age. CUS is a non-invasive and portable technique that allows for repeated examinations without risk of radiation exposure. However, CUS has some limitations in visualizing certain deep or posterior structures of the brain.
Cataract
A cataract is a clouding or opacity that
develops in the crystalline lens of the eye or in its envelope, varying in degree from slight opacity to obstructing the passage of light.
Progressive, painless clouding of the natural, internal lens of the eye.
Keratoconus - Dr Shylesh B Dabke
This document provides information on keratoconus, a noninflammatory corneal ectasia characterized by progressive corneal thinning and protrusion. It discusses the etiology, pathophysiology, clinical features, diagnosis, and treatment modalities for keratoconus. Treatment options include spectacle correction, contact lenses, intrastromal corneal ring segments, collagen cross-linking, and corneal transplantation if visual correction is no longer possible due to excessive thinning or scarring.
PARS PLANA VITRECTOMY FOR LENS DROP.pptx
Pars plana vitrectomy is a microsurgical procedure to remove the vitreous body through the pars plana. The document outlines the history, indications, risks, pre-operative assessment, surgical procedure, complications, and outcomes of pars plana vitrectomy for dropped lens fragments following cataract surgery. Key points include performing vitrectomy within 1 week of a dropped nucleus for best visual outcomes, using fragmatomes or vitrectomy cutters to remove fragments, examining the periphery for retinal tears, and achieving useful vision in 60-80% of cases with timely intervention.
LASIK Surgery is Safe in the Long-Term
The document discusses the long-term safety of LASIK based on over 50 years of lamellar corneal surgery experience. While early studies in the 2000s showed limited long-term data, newer screening techniques like epithelial thickness mapping and advances in technology have improved safety outcomes. Keratomileusis procedures from the 1970s demonstrated ectasia risks can be minimized through accurate screening and limiting resection depth and diameter.

PCR.pptx
1) Posterior capsule rent (PCR) is a breach in the posterior capsule of the crystalline lens during cataract surgery that can lead to suboptimal visual outcomes if not properly managed.
2) Predisposing factors for PCR include patient-related factors like age and ocular conditions, surgeon-related factors like experience, and intraoperative factors like cataract type and surgical techniques.
3) Preventive strategies include comprehensive preoperative evaluation, proper wound construction, ensuring an intact capsulorhexis, and gentle hydrodissection. Management of PCR involves anterior vitrectomy using techniques like bimanual vitrectomy and triamcinolone to visualize vitreous, followed by careful cortical removal
Complex cases in Cataract surgery and its management.pptx
In ophthalmology the clinical management of patients is constantly evolving and complication rate is getting low.
Although routine cataract surgery considered as low-risk surgery for both patients and the surgeon, some eyes have higher risk of complications.
It is extremely important to recognize when eyes are at greater risk, and manage accordingly to reduce the complications.
The common goal is to completely remove the cataract while preserving the zonules and capsular bag for the placement of an IOL.
Fuchs’ endothelial corneal dystrophy (FECD) is a condition that affects the corneal endothelium, resulting in a reduction in the number of Na+/K+ ATPase pumps [1]. Clinically, this manifests as corneal edema, which can lead to symptomatic glare and halos, and ultimately decreased visual acuity.

Case report on post lasik ecstasia
This case report describes a 31-year-old woman who presented with post-LASIK ectasia in both eyes. She had undergone LASIK in 2010 and her vision remained stable for two years, but then she began experiencing decreased vision in her right eye. Examinations confirmed ectatic changes bilaterally. She was fitted with rigid gas permeable lenses, achieving good vision and comfort. The final lens order was a 7.40mm lens for her right eye and an 8.80mm lens for her left eye. Post-LASIK ectasia occurs when the integrity of the cornea is compromised following refractive surgery, leading to corneal warping.
Femtosecond Laser Cataract Surgery- Magic or Myth? A Balanced View
Femtosecond lasers are being touted as the next great leap forward in cataract surgery but, as with any radical change to our practices, many questions remain: Does this technology truly improve cataract surgery? Is the refractive accuracy better? Is the safety profile significantly elevated compared to existing technologies? Are there additional complications or issues with using this laser?

Ocular surface squamous neoplasia
[1] Ocular Surface Squamous Neoplasia (OSSN) refers to a spectrum of dysplastic and malignant squamous lesions of the conjunctiva and cornea.
[2] Diagnosis is usually clinical but can be confirmed with biopsy. For suspected OSSN less than 3 clock hours, excision biopsy with cryotherapy and alcohol epitheliectomy is performed. Larger lesions may require chemoreduction with topical chemotherapy prior to surgery and cryotherapy.
[3] Risk factors include ultraviolet light, HIV, and human papillomavirus. While rare, metastasis can occur to local lymph nodes or distant sites like lungs. Recurrence after treatment ranges from 15-52% depending
Management of adult cataract II.ppt
This document discusses the pre-operative evaluation and management of adult cataract patients. It covers types of cataract surgery, including ICCE and ECCE. The pre-operative evaluation involves assessing general health, medical history, ocular history, visual function testing, and external and internal eye examination. Key areas of focus include evaluating for other ocular conditions, optimizing medical comorbidities, and determining the visual impact of the cataract to guide surgical planning and post-operative expectations.
Management of adult cataract II.ppt
This document discusses the pre-operative evaluation and management of adult cataract patients. It describes the types of cataract surgery as ICCE and ECCE. ECCE has replaced ICCE due to better equipment and IOL implants. A thorough pre-operative evaluation includes medical history, ocular examination, measurements of visual function, and potential acuity tests to determine the contribution of the cataract to visual loss. Special tests can evaluate macular and retinal function when the cataract obscures fundus view.
Management of adult cataract II.ppt
This document discusses the management of adult cataract, including types of cataract surgery, pre-operative evaluation, and measurements of visual function. It describes extracapsular cataract extraction (ECCE) and intracapsular cataract extraction (ICCE), and notes that ECCE has replaced ICCE due to improved technology. The pre-operative evaluation involves assessing general health, ocular history, medications, visual function tests, and external and internal eye examination. Measurements of visual function include visual acuity, brightness acuity, contrast sensitivity, and visual field testing.
Nucleus drop
1) A nucleus drop occurs when part or all of the lens nucleus falls into the vitreous cavity during cataract surgery. It has a low incidence rate of around 0.3%.
2) Risk factors include preexisting conditions like pseudoexfoliation or zonular weakness, as well as complications during surgery such as tears in the posterior capsule or zonules.
3) Definitive management involves a pars plana vitrectomy to remove the dropped nucleus and any remaining vitreous gel. This helps minimize complications like uveitis, glaucoma, or retinal detachment.
Role of oct in glaucoma
Optical coherence tomography (OCT) is useful for imaging both the anterior and posterior segments in glaucoma. Posterior segment OCT allows quantification of retinal nerve fiber layer thickness, optic nerve head parameters, and ganglion cell layer thickness. Changes in these measurements over time can help detect glaucomatous progression. Anterior segment OCT visualizes angle anatomy and structures after glaucoma surgery. OCT provides objective data but results must be interpreted carefully while considering limitations such as variability between devices and lack of representation in normative databases.
Gadgets in neuro
This document discusses various gadgets used in neurosurgery including neuronavigation systems. Neuronavigation uses preoperative images like CT and MRI to provide navigation during surgery. It helps localize lesions, perform biopsies and resections, and avoid damaging eloquent areas. Accuracy is typically around 2mm. While helpful, it can be time-consuming and restrict head movement. Future developments may involve microsurgical robots to compensate for brain shift. Fluorescence imaging using agents like 5-ALA and sodium fluorescein can also help identify tumor margins during surgery but have limitations. Overall, neuronavigation and fluorescence are useful adjuncts but experience and anatomy knowledge remain important.
cataract surgery.pptx
Cataract surgery has evolved over time from older techniques like intracapsular cataract extraction (ICCE) that involved removing the entire lens to extracapsular cataract extraction (ECCE) and modern phacoemulsification. ICCE required a large incision and carried high risks of complications like vitreous prolapse. ECCE removed just the lens contents through a larger incision that required suturing. Modern phacoemulsification uses ultrasonic probes introduced through a small 3mm self-sealing incision to break up and remove the lens with reduced risks of complications like induced astigmatism compared to older methods. Potential complications of cataract surgery include posterior capsule rupture,
Fundus evaluation - special test for cataract surgery
The ophthalmologist performs a full fundus examination to evaluate the macula, optic nerve, vitreous, retinal vessels, and periphery. Special attention is paid to conditions like macular degeneration that could limit visual outcomes after cataract surgery. Patients with diabetes are examined carefully for retinal complications. Additional tests like ultrasonography, potential acuity estimation, and optical coherence tomography may be used when the lens prevents a clear view of the fundus or to further evaluate the macula, optic nerve, or retina. These evaluations help determine if the patient is a good candidate for cataract surgery and what visual outcomes may be expected.

Additional tests like ultrasonography, potential acuity estimation, and optical coherence tomography may be used when the lens prevents a clear view of the fundus or to further evaluate the macula, optic nerve, or retina. Assessment of the cornea and visual fields can also provide useful information for surgical planning and post-operative counseling.
OCT in coronary PCI
This document discusses optical coherence tomography (OCT) in coronary artery disease. It provides an overview of OCT, including its history and clinical evidence. It then outlines how to perform an OCT study and presents an algorithmic approach to interpreting OCT images, including assessing plaque morphology, stent sizing and apposition. The document discusses several clinical applications of OCT, such as evaluating acute coronary syndrome, plaque vulnerability, and stent failure. It also reviews limitations and future directions of OCT, including hybrid OCT/IVUS catheters and the use of artificial intelligence.
Endophthalmitis
1. Endophthalmitis is an intraocular inflammation that predominantly affects the inner spaces of the eye.
2. It can be classified as infectious (exogenous or endogenous) or non-infectious. The most common type is exogenous endophthalmitis, which accounts for over 85% of cases.
3. Treatment depends on the type and severity of endophthalmitis. For acute postoperative endophthalmitis with vision of light perception or worse, immediate pars plana vitrectomy and intravitreal antibiotics is recommended. For vision of hand motions or better, a tap and inject of intravitreal antibiotics is recommended initially.

Title: Gravitational wave detection with orbital motion of Moon and artificial
Abstract:
In this talk I will describe some recent ideas to find gravitational waves from supermassive black holes or of primordial origin by studying their secular effect on the orbital motion of the Moon or satellites that are laser ranged.waterlessdyeingtechnolgyusing carbon dioxide chemicalspdf
The technology uses reclaimed CO₂ as the dyeing medium in a closed loop process. When pressurized, CO₂ becomes supercritical (SC-CO₂). In this state CO₂ has a very high solvent power, allowing the dye to dissolve easily.

EWOCS-I: The catalog of X-ray sources in Westerlund 1 from the Extended Weste...
Context. With a mass exceeding several 104 M⊙ and a rich and dense population of massive stars, supermassive young star clusters
represent the most massive star-forming environment that is dominated by the feedback from massive stars and gravitational interactions
among stars.
Aims. In this paper we present the Extended Westerlund 1 and 2 Open Clusters Survey (EWOCS) project, which aims to investigate
the influence of the starburst environment on the formation of stars and planets, and on the evolution of both low and high mass stars.
The primary targets of this project are Westerlund 1 and 2, the closest supermassive star clusters to the Sun.
Methods. The project is based primarily on recent observations conducted with the Chandra and JWST observatories. Specifically,
the Chandra survey of Westerlund 1 consists of 36 new ACIS-I observations, nearly co-pointed, for a total exposure time of 1 Msec.
Additionally, we included 8 archival Chandra/ACIS-S observations. This paper presents the resulting catalog of X-ray sources within
and around Westerlund 1. Sources were detected by combining various existing methods, and photon extraction and source validation
were carried out using the ACIS-Extract software.
Results. The EWOCS X-ray catalog comprises 5963 validated sources out of the 9420 initially provided to ACIS-Extract, reaching a
photon flux threshold of approximately 2 × 10−8 photons cm−2
s
−1
. The X-ray sources exhibit a highly concentrated spatial distribution,
with 1075 sources located within the central 1 arcmin. We have successfully detected X-ray emissions from 126 out of the 166 known
massive stars of the cluster, and we have collected over 71 000 photons from the magnetar CXO J164710.20-455217.
ESR spectroscopy in liquid food and beverages.pptx
With increasing population, people need to rely on packaged food stuffs. Packaging of food materials requires the preservation of food. There are various methods for the treatment of food to preserve them and irradiation treatment of food is one of them. It is the most common and the most harmless method for the food preservation as it does not alter the necessary micronutrients of food materials. Although irradiated food doesn’t cause any harm to the human health but still the quality assessment of food is required to provide consumers with necessary information about the food. ESR spectroscopy is the most sophisticated way to investigate the quality of the food and the free radicals induced during the processing of the food. ESR spin trapping technique is useful for the detection of highly unstable radicals in the food. The antioxidant capability of liquid food and beverages in mainly performed by spin trapping technique.
The binding of cosmological structures by massless topological defects
Assuming spherical symmetry and weak field, it is shown that if one solves the Poisson equation or the Einstein field
equations sourced by a topological defect, i.e. a singularity of a very specific form, the result is a localized gravitational
field capable of driving flat rotation (i.e. Keplerian circular orbits at a constant speed for all radii) of test masses on a thin
spherical shell without any underlying mass. Moreover, a large-scale structure which exploits this solution by assembling
concentrically a number of such topological defects can establish a flat stellar or galactic rotation curve, and can also deflect
light in the same manner as an equipotential (isothermal) sphere. Thus, the need for dark matter or modified gravity theory is
mitigated, at least in part.
Immersive Learning That Works: Research Grounding and Paths Forward
We will metaverse into the essence of immersive learning, into its three dimensions and conceptual models. This approach encompasses elements from teaching methodologies to social involvement, through organizational concerns and technologies. Challenging the perception of learning as knowledge transfer, we introduce a 'Uses, Practices & Strategies' model operationalized by the 'Immersive Learning Brain' and ‘Immersion Cube’ frameworks. This approach offers a comprehensive guide through the intricacies of immersive educational experiences and spotlighting research frontiers, along the immersion dimensions of system, narrative, and agency. Our discourse extends to stakeholders beyond the academic sphere, addressing the interests of technologists, instructional designers, and policymakers. We span various contexts, from formal education to organizational transformation to the new horizon of an AI-pervasive society. This keynote aims to unite the iLRN community in a collaborative journey towards a future where immersive learning research and practice coalesce, paving the way for innovative educational research and practice landscapes.

Describing and Interpreting an Immersive Learning Case with the Immersion Cub...
Current descriptions of immersive learning cases are often difficult or impossible to compare. This is due to a myriad of different options on what details to include, which aspects are relevant, and on the descriptive approaches employed. Also, these aspects often combine very specific details with more general guidelines or indicate intents and rationales without clarifying their implementation. In this paper we provide a method to describe immersive learning cases that is structured to enable comparisons, yet flexible enough to allow researchers and practitioners to decide which aspects to include. This method leverages a taxonomy that classifies educational aspects at three levels (uses, practices, and strategies) and then utilizes two frameworks, the Immersive Learning Brain and the Immersion Cube, to enable a structured description and interpretation of immersive learning cases. The method is then demonstrated on a published immersive learning case on training for wind turbine maintenance using virtual reality. Applying the method results in a structured artifact, the Immersive Learning Case Sheet, that tags the case with its proximal uses, practices, and strategies, and refines the free text case description to ensure that matching details are included. This contribution is thus a case description method in support of future comparative research of immersive learning cases. We then discuss how the resulting description and interpretation can be leveraged to change immersion learning cases, by enriching them (considering low-effort changes or additions) or innovating (exploring more challenging avenues of transformation). The method holds significant promise to support better-grounded research in immersive learning.
