Indirect ophthalmoscopy
Indirect ophthalmoscopy allows examination of the peripheral fundus and posterior pole. It should be used when examining patients with symptoms suggesting retinal abnormalities or those with systemic diseases affecting the retina. Indirect ophthalmoscopy involves placing a high-power convex lens in front of the eye to form a real, inverted image of the fundus. There are two methods: monocular uses a handheld lens and provides an erect image, while binocular allows stereoscopic viewing. Proper technique involves dilating the pupil and using a condensing lens held near the eye to view the magnified retinal image.

VISUAL FIELD by suraj chhetri
This document summarizes kinetic versus static perimetry and automated perimetry. Kinetic perimetry involves moving a stimulus across the visual field to plot isopters, while static perimetry measures sensitivity at fixed retinal locations. Automated perimetry uses static techniques with computer control, allowing tests like Humphrey and Octopus to efficiently and objectively measure thresholds across the visual field.
Synoptophore
The synoptophore is an ophthalmic instrument used to diagnose and treat imbalances of the eye muscles. It consists of two cylindrical tubes with mirrored bends that allow pictures to be presented simultaneously to both eyes, compensating for any angle of squint. It is used to investigate binocular function in patients with a manifest squint, detect suppression and abnormal retinal correspondence, and measure horizontal, vertical and torsional misalignments. The synoptophore can test for three grades of binocular vision - simultaneous perception, fusion, and stereopsis - and detect whether a patient has normal or abnormal retinal correspondence based on differences between subjective and objective angles of squint.
Retinoscopy
Retinoscopy for undergraduates and post-graduates.
salient points covering examinations and PGMEE.
Detailed discussion of the technique of retinoscopy and its utility in deducing refractive errors.
Use of cycloplegic refraction and subjective refraction has been discussed.
Perimetry
This document summarizes key aspects of perimetry testing. It defines the normal visual field and describes how perimetry can be used to detect functional vision loss and monitor disease progression. Two main types of perimetry are discussed: kinetic and static. Details are provided on testing strategies, stimuli brightness, interpreting results like total deviation and reliability indices. The document emphasizes the importance of perimetry in glaucoma and neurological diagnosis and management.
Corneal topography
The cornea is the main refractive element of the eye, contributing 70% of the eye's refractive power. Even minor changes to its shape can significantly alter the image formed on the retina. The cornea has an elliptical anterior surface and a circular posterior surface. It varies in thickness from center to periphery. Corneal topography is used to map the shape of the cornea using various techniques such as Placido disk, elevation-based, and Scheimpflug imaging. Topography provides quantitative data on corneal curvature, thickness, and irregularities that aid in diagnosing conditions like keratoconus.
Amsler grid
The document summarizes the Amsler grid, a diagnostic tool used since 1945 to screen for and monitor macular diseases. It consists of a grid with a central dot that patients look at to detect any distortions, gaps, or blurred areas in their central vision. Various versions are available, including ones with different colors, patterns of lines, or dot sizes to test specific parts of the visual field and detect different types of visual abnormalities that could indicate conditions like macular degeneration or glaucoma. The procedure involves having patients view the grid with each eye separately at 16 inches and report any anomalies in the lines of the grid.
Perimetry 1
The document discusses principles of perimetry, which is the measurement of visual functions across the visual field. It describes the history of automated perimeters beginning in 1970. Static perimetry uses computerized testing to determine contrast sensitivity thresholds at preset locations, while kinetic perimetry manually maps sensitivity points along meridians. Both methods are used to identify decreases in retinal sensitivity indicative of conditions like glaucoma. Automated static perimetry provides quantifiable and reproducible data but is time-consuming, while kinetic perimetry rapidly defines field contours but requires more operator skill.
Synaptophore in ophthalmology
The synaptophore is a device used to measure binocular vision anomalies. It consists of two optical tubes that can be adjusted horizontally, vertically, and torsionally. Various slides are used for diagnostic and treatment purposes to measure deviations, fusion, stereopsis, and retinal correspondence. Key measurements include the objective and subjective angles of deviation in different gazes, as well as the fusional ranges in horizontal, vertical, and torsional planes. Suppression can also be detected and mapped out. Precise adjustments of the tubes allow customized orthoptic treatment of binocular vision disorders.
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.
Slit Lamp Illumination Techniques
This document describes various illumination techniques used with a slit lamp to examine different parts of the eye. It discusses diffuse, direct, tangential, and specular illumination techniques as well as indirect, retroillumination, and Van Herrick techniques. Each technique is used to illuminate a specific area of the eye in order to observe different structures like the cornea, iris, lens, anterior chamber angle, and detect any pathologies present. Proper illumination angles and magnifications are outlined for visualizing various eye tissues and evaluating properties like surface texture and integrity.
Corneal pachymetry by ben okeeffe
Corneal pachymetry uses ultrasound to measure the thickness of the cornea, known as central corneal thickness. It is useful for assessing risk for corneal refractive surgery, transplant, and glaucoma. Ultrasound pachymetry is the preferred method as it is easy to perform, reproducible, and precise. The measurement aids in screening and management of conditions that affect corneal thickness like glaucoma, transplant rejection, and keratoconus.
Keratoconus and management
Keratoconus is a degenerative eye condition where the cornea thins and changes shape, causing vision problems. The cause is unknown but risk factors include eye rubbing and genetics. Symptoms include progressively worsening vision not fully corrected by glasses. Diagnosis involves examining the cornea shape using keratometry and topography to detect thinning, steepening, and irregular astigmatism. Mild cases may need no treatment, while progressive cases can be managed with contact lenses or corneal cross-linking depending on severity.
Mallet Unit
Fixation disparity is a measurement of the amount of prism needed to eliminate retinal disparity when fixating centrally and peripherally. It is commonly measured in Mallett units in the UK using red and green markers at different distances and fixation points. The amount of prism required to eliminate fixation disparity does not necessarily correspond to the size of the heterophoria and may not always relate to symptoms. Fixation disparity should be used along with other vergence and binocular vision tests in a full clinical assessment.
Hfa
This document discusses visual field testing and perimetry. It defines the visual field and describes common visual field defects. It then covers the indications, methods, and terminology of visual field testing. Specific details are provided on threshold testing strategies, reliability indices, and how to interpret visual field printout maps and global indices. Criteria for diagnosing glaucomatous visual field loss and detecting progression over time are also outlined.
Slit lamp biomicroscopy
The document discusses the history and components of the slit lamp biomicroscopy instrument, which provides a 3D view of ocular structures. It describes the illumination and observation systems, examination techniques including different types of illumination, and attachments used with the slit lamp. The various illumination techniques allow examination of different ocular structures by changing the light beam properties.
worth 4 dot test.pptx
The Worth Four Dot test is used to assess binocular vision. It presents four lights - red, green, green, white - through red-green glasses. The test checks for suppression or diplopia by asking the patient to report the number, color, and position of lights seen. Abnormal responses can indicate conditions like strabismus, suppression in one eye, or vertical/horizontal diplopia from deviations. The test is inexpensive and easy to perform but relies on subjective patient responses.
Binocular refraction techniques, binocular balancing & binocular
Binocular refraction techniques aim to evaluate a patient's refractive status under binocular viewing conditions. This allows for the detection of suppression, measurement of stereopsis and fixation disparity. Techniques include using a septum, polarization, or fogging to allow each eye to view separate targets while maintaining binocular fusion. Binocular balancing ensures the retinal images are simultaneously in focus for both eyes. The binocular best sphere finds the spherical prescription providing maximum binocular visual acuity. Binocular refraction at near is also important to evaluate a patient's refractive needs for near vision tasks.
Real subjective refraction in astigmatism
1) The document discusses subjective refraction techniques for astigmatism, including determining the spherical and cylindrical corrections.
2) Key steps include controlling accommodation, finding the monocular best sphere using VA or bichrome tests, and determining the cylindrical component using fogging with targets like clock dials or Jackson cross cylinders.
3) The axis of the cylindrical correction must match the axis of the patient's astigmatism to fully correct their refractive error.
Lensometry.
The document discusses lensometry, which is the process of using a lensometer or lensmeter to measure the optical properties of lenses. A lensometer projects lines that allow optometrists to determine information like the sphere, cylinder, and axis measurements specified in a prescription. It can also verify the accuracy of lenses and detect their type (spherical, astigmatic, prismatic). Lensometers are used to properly fit lenses into frames and ensure prescriptions are correct. The document outlines the history of the lensometer's invention and provides details on its use, parts, manual operation, and the measurements it can obtain for different lens types like bifocals.
Pentacam analysis
The document discusses parameters for analyzing corneal topography scans from the Pentacam. It describes various indices and maps generated by the Pentacam that are used to evaluate corneal shape, thickness, and biomechanical properties. Key parameters include the ISV, IVA, IHA, and IHD indices, BAD-D values, PPI and ART values, and the 13-point algorithm classification. Together these provide a comprehensive overview of corneal shape and help distinguish normal corneas from those with conditions like keratoconus.
B SCAN
B-scan ultrasonography uses high frequency sound waves to produce 2D images of ocular structures. It can be used to evaluate the anterior segment, posterior segment, tumors, vitreous pathology, retinal detachments, and more. The probe transmits sound waves which bounce off tissues and return echoes that are amplified and displayed. This allows visualization of the retina, choroid, lens, vitreous humor and other structures. B-scan is useful for diagnosing and monitoring many ocular conditions.

Cell Therapy Expansion and Challenges in Autoimmune Disease
There is increasing confidence that cell therapies will soon play a role in the treatment of autoimmune disorders, but the extent of this impact remains to be seen. Early readouts on autologous CAR-Ts in lupus are encouraging, but manufacturing and cost limitations are likely to restrict access to highly refractory patients. Allogeneic CAR-Ts have the potential to broaden access to earlier lines of treatment due to their inherent cost benefits, however they will need to demonstrate comparable or improved efficacy to established modalities.
In addition to infrastructure and capacity constraints, CAR-Ts face a very different risk-benefit dynamic in autoimmune compared to oncology, highlighting the need for tolerable therapies with low adverse event risk. CAR-NK and Treg-based therapies are also being developed in certain autoimmune disorders and may demonstrate favorable safety profiles. Several novel non-cell therapies such as bispecific antibodies, nanobodies, and RNAi drugs, may also offer future alternative competitive solutions with variable value propositions.
Widespread adoption of cell therapies will not only require strong efficacy and safety data, but also adapted pricing and access strategies. At oncology-based price points, CAR-Ts are unlikely to achieve broad market access in autoimmune disorders, with eligible patient populations that are potentially orders of magnitude greater than the number of currently addressable cancer patients. Developers have made strides towards reducing cell therapy COGS while improving manufacturing efficiency, but payors will inevitably restrict access until more sustainable pricing is achieved.
Despite these headwinds, industry leaders and investors remain confident that cell therapies are poised to address significant unmet need in patients suffering from autoimmune disorders. However, the extent of this impact on the treatment landscape remains to be seen, as the industry rapidly approaches an inflection point.
ABDOMINAL TRAUMA in pediatrics part one.
Abdominal trauma in pediatrics refers to injuries or damage to the abdominal organs in children. It can occur due to various causes such as falls, motor vehicle accidents, sports-related injuries, and physical abuse. Children are more vulnerable to abdominal trauma due to their unique anatomical and physiological characteristics. Signs and symptoms include abdominal pain, tenderness, distension, vomiting, and signs of shock. Diagnosis involves physical examination, imaging studies, and laboratory tests. Management depends on the severity and may involve conservative treatment or surgical intervention. Prevention is crucial in reducing the incidence of abdominal trauma in children.
