Autorefractometer
An autorefractor or automated refractor is a computer-controlled machine used during an eye examination to provide an objective measurement of a person's refractive error and prescription for glasses or contact lenses. This is achieved by measuring how light is changed as it enters a person's eye. Autorefractometer is a Instruement which is using in optometrist and Opthalmologist clinic for objective refraction.
Now a days autorefractometer is very usefull Instruement for the refraction than retinoscope
A-V pattern strabismus
The document discusses patterns of strabismus, specifically the A pattern and V pattern. The A pattern involves relative convergence on upgaze and divergence on downgaze, while the V pattern is the opposite with relative divergence on upgaze and convergence on downgaze. Variants include the X, Y, lambda, and diamond patterns. The etiology of these patterns involves dysfunction of the horizontal, vertical, or oblique eye muscles. Clinical features may include anomalous head posture, amblyopia, and abnormal retinal correspondence. Diagnosis involves measuring alignment in upgaze and downgaze while preventing accommodation.

divergent squint.pptx
This document discusses exodeviations, or divergent strabismus, which is when the visual axis is deviated laterally and the fovea is rotated nasally. It describes the different types of exodeviations including comitant deviations like infantile exotropia and incomitant deviations caused by paralysis or muscle restrictions. Symptoms, causes, and treatments for various exodeviations are outlined, with non-surgical treatments including prism therapy and orthoptic exercises, and surgical treatments involving lateral rectus recession and medial rectus resection.
RGP contact lens fitting
This ppt is based in the topic of contact lens fitting of the RGP type contact lens. this is one of my university assignment. i am currently the student of centurion university of technology and management located in odisha.
Presbyopia
Presbyopia is the age-related loss of accommodation due to reduced elasticity and flexibility of the lens. It begins in the 40s and progresses until complete loss of accommodation in the 50s-60s. Theories explain it is caused by reduced ciliary muscle contraction and increased lens diameter with age. Symptoms include difficulty with near vision, especially in low light. Treatments include reading glasses, contact lenses, and refractive surgeries like LASIK, conductive keratoplasty, and multifocal lenses. The goal is to improve near vision while maintaining good distance vision.
Glazing
This document summarizes the process of glazing, which involves fitting lenses into spectacle frames. It discusses the key steps of laying off markings on the lens, lens cutting and edging, and fitting. Lens cutting historically involved manually outlining and chipping lenses, but now is done automatically by edgers. Edging shapes the lens to the frame and creates a bevel. Edging can be done manually with ceramic or diamond wheels or automatically through pattern or patternless edging, where data from a frame tracer is used to directly edge the lens without a pattern. The lens is then fitted into the frame.
Vision standards for various occupation
This document outlines visual standards for driving and naval service. The key points are:
- For driving, the standard is 6/9 vision in the better eye or 6/12 in the worse eye, with a field of vision of at least 120 degrees. Diplopia and certain visual field defects make one unfit to drive.
- For the Royal Navy, the standards are 6/12 vision or better in each eye, with restrictions on hyperopia, myopia and astigmatism. Tests include Ishihara color plates and checking binocular function.
- Factors like ocular pathology, refractive surgeries and retinal detachment could cause rejection even if vision is within standards. Spectacle

Real pediatric refraction and spectacle power prescription in pediatrics.
The document discusses pediatric refraction and spectacle prescription. It covers several topics including emmetropization, refractive changes with age, types of pediatric refraction such as near retinoscopy and cycloplegic refraction, and considerations for spectacle prescription in children. Cycloplegic refraction is recommended for all non-verbal children to fully paralyze the ciliary muscles and determine the total refractive error, as the eye's refraction can change dramatically during development. The challenges of pediatric refraction include a child's ability to accommodate and their lack of cooperation, emphasizing the need for objective refraction techniques.
Maddox rod, Maddox wing, Bagolini striated glasses, RAF ruler and Prism bar
The Maddox rod test is used to detect heterophoria or heterotropia. It consists of a series of cylindrical lenses mounted in a trial frame that produces an elongated streak of light. When viewed through the Maddox rod, a spot of light appears as a streak. The orientation of the streak indicates whether the eye is deviated vertically or horizontally. The test is easy for patients to understand and perform, and useful for detecting vertical deviations.
Exodeviations
1. Exodeviations, or divergent strabismus, involve lateral deviation of the visual axis and nasal rotation of the fovea. The main types are exophoria, intermittent exotropia, and manifest exotropia.
2. Causes of exodeviations include excessive tonic divergence, anatomical factors in the orbit, and high accommodative convergence to accommodation ratio.
3. Treatment involves correcting refractive errors and amblyopia non-surgically and recessing the lateral rectus or resecting the medial rectus surgically depending on the type and amount of deviation. The goal of surgery is a small overcorrection to stabilize binocular alignment.
Spectacle dispensing in elderly.pptx
This document discusses several key considerations for providing eye care to elderly patients. It notes that the elderly population is one of the fastest growing internet users and will require more frequent eye exams. It highlights that aging brings natural changes to vision that should be addressed sensitively. Examinations and dispensing processes should be thorough and explain recommendations in detail while showing personal attention. Multiple pairs of eyewear are often needed to meet the varied visual needs of elderly patients for tasks like reading, computers, and driving. Lens material, coatings, and frame fit considerations are especially important for comfort.
Iol master
This document discusses the history of intraocular lens (IOL) implantation and development of technologies for calculating IOL power. It begins with Sir Harold Ridley implanting the first IOL in 1949 using the human lens as a model. Over subsequent decades, improvements were made such as developing foldable lenses to allow for smaller incisions. Advances in biometry technologies like ultrasound A-scan and optical biometry using partial coherence interferometry allowed for more accurate measurements of eye dimensions needed for precise IOL power calculations.
CENTRAL SEROUS CHORIO RETINOPATHY
This document provides an overview of central serous chorioretinopathy (CSC), including its pathogenesis, clinical presentation, diagnosis, course and treatment. CSC is characterized by a localized serous retinal detachment in the macula due to leakage of fluid from the choroid. It typically affects men ages 30-50 and can be associated with stress, corticosteroid use, hypertension and type A personality. Diagnosis is usually clinical but can be confirmed with fluorescein angiography showing characteristic leakage patterns or optical coherence tomography identifying subretinal fluid. While most cases resolve spontaneously, laser photocoagulation or photodynamic therapy may be used in persistent or recurrent cases to seal leaking sites and accelerate resolution.
Accommodative esotropia
This document discusses different types of esotropia (inward eye turning), including accommodative esotropia caused by uncorrected refractive errors, convergence excess esotropia caused by a high AC/A ratio, and early onset esotropia appearing before age 6 months. Accommodative esotropia is treated initially with corrective lenses, while convergence excess may require bifocals or surgery. Early onset esotropia often requires surgery by age 1-2 years to align the eyes, with risks of undercorrection, amblyopia, or development of dissociated vertical deviation. The document provides details on diagnostic criteria and management approaches for various forms of esotropia.
Binocular balancing
1. Binocular balancing ensures equal accommodation relaxation in both eyes during subjective refraction. It does not aim to equalize visual acuity between eyes.
2. There are several techniques for binocular balancing, including successive alternate occlusion, vertical prism dissociation, fogging/Humphiss test, polarized filters, and the septum technique. These techniques add plus lenses until the patient reports equal blurriness between eyes.
3. The vertical prism dissociation technique uses prisms to displace one eye's image vertically while fogging is used, and plus lenses are added until equal blur is reported. The polarized technique uses polarizing filters to partially separate the images while the sept
Types of pediatric contact lens [autosaved]
This document discusses pediatric contact lens fitting and evaluation. It begins by outlining the advantages of contact lenses over glasses for children, including a wider field of view. Key considerations for fitting include small eye size, tear production, and compliance. Conditions that may require lenses include refractive errors, amblyopia treatment, and aphakia following cataract surgery. Evaluations include testing visual acuity and ocular health. Lens options discussed are silicone, hydrogel, and rigid gas permeable lenses. Special fitting considerations for aphakic children include initially high powers of +20D to +35D, depending on age.
Presbyopia
This document summarizes presbyopia, including its causes, symptoms, signs, and treatment options. Presbyopia is an age-related condition where the lens loses its ability to accommodate for near vision, typically starting after age 40. Symptoms include headaches and blurred near vision. Treatment options include bifocal, trifocal, or progressive addition lenses, contact lenses using monovision or multifocal designs, and surgical options like PRELEX. Bifocal lens designs like Kryptok and executive styles are preferred depending on whether the patient is myopic or hyperopic. Progressive lenses provide distance, intermediate, and near vision zones without visible lines.
Esotropia , classification , diagnosis and management
This document provides information on various types of esotropia (convergent strabismus), including:
- Accommodative esotropia caused by uncorrected hyperopia or a high AC/A ratio
- Partially accommodative esotropia with both accommodative and non-accommodative components
- Non-accommodative esotropia including convergence excess, cyclical esotropia, and acquired forms
- Esotropia associated with high myopia or nystagmus is also discussed
Treatment options including refractive correction, orthoptic exercises, prisms, botulinum toxin, and surgery are mentioned for different types of esotropia.
A scan
A-scan ultrasonography uses sound waves to produce spikes corresponding to tissue interfaces in the eye. The height of the spikes depends on factors like the difference in tissue densities, the angle of the sound beam, and the shape and size of interfaces. A-scan is used to measure axial length and corneal thickness, with the quality affected by issues like oblique beam incidence, irregular macular surfaces, and dense cataracts that absorb more sound.
Aphakia
- Aphakia is the absence of the crystalline lens from the eye. It can be congenital or caused by surgery or trauma.
- In aphakia, the eye becomes highly hyperopic, the anterior focal point moves forward, and the retinal image is magnified. This decreases visual acuity and field of view.
- Aphakia is treated with spectacles, contact lenses, or intraocular lenses. Spectacles cause issues like increased image size, ring scotomas, and reduced field of view. Contact lenses and IOLs provide better image quality but have risks of complications.
Keratometry
Keratometry is used to measure the curvature of the cornea by analyzing the reflection of light off its surface. It works by projecting illuminated circles called mires onto the cornea and measuring the size of the reflected image to calculate the radius of curvature. The main uses of keratometry include measuring corneal astigmatism, estimating contact lens power, and detecting irregularities like keratoconus. Modern instruments automate the process but traditional keratometers require aligning the mires and adjusting knobs until the doubled images come into close alignment. Factors like blinking, eye movements, and irregular corneas can impact the accuracy of measurements.
Biometry made easy
Biometry is used to measure the eye to determine the correct intraocular lens power for cataract surgery. It involves measuring the corneal power with keratometry and the eye length with axial length measurement. The optimal method is optical biometry which measures both simultaneously while allowing the patient to fixate, improving accuracy. Special cases like high myopia, prior refractive surgery, or pathology require adjusted measurement techniques or formulas to calculate the lens power accurately.
Visual acuity by pd
Visual acuity and contrast sensitivity are measures of visual function. Visual acuity is the ability to see details and is usually measured using an eye chart. It quantifies the smallest object a person can see at a given distance. Contrast sensitivity measures the ability to detect differences in luminance and provides information about object edges and borders. It is assessed using tests with patterns of varying contrast such as gratings or letter charts. Both visual acuity and contrast sensitivity are important for tasks of daily living and can be evaluated through standardized tests.
Objective refraction
This document discusses objective refraction techniques, primarily retinoscopy. It begins by explaining the principles of retinoscopy, including far point concept and how different ametropias affect the far point. It then describes the components and optics of the retinoscope, how it works, and retinoscopy techniques. Key aspects covered include neutralization, prerequisites for retinoscopy, and problems that can occur. Autorefractometry is also briefly discussed. In under 3 sentences:
Retinoscopy is the primary objective refraction technique discussed, which uses a retinoscope to illuminate the retina and observe the movement of the red reflex to determine the refractive error, neutralizing with trial lenses. The document covers the optics
Cycloplegic refraction.pptx
Cycloplegic refraction involves using eye drops to paralyze the focusing muscles of the eye in order to get a more accurate measurement of a person's refractive error without influence from accommodation. It is particularly useful for children, people with hyperopia or esotropia, those with presbyopia symptoms at a young age, and for evaluating candidates for refractive surgery. While the drops cause temporary blurry vision and light sensitivity, they allow the full refractive error to be determined and properly corrected.
Real pediatric visual acuity assessment
This document discusses various methods for assessing visual acuity in pediatric patients from infants to school-aged children. It begins by outlining visual milestones in infant development and different techniques used for infants, including optokinetic nystagmus testing, preferential looking tests, Cardiff acuity testing, and visually evoked potentials. Methods for toddlers are then reviewed, such as dot visual acuity tests, coin tests, miniature toy tests, Sheridan's ball test, and Boek's candy test. The document concludes by emphasizing the importance of early visual acuity assessment and addressing challenges in pediatric assessment.
By pd aphakia & pseudophakia
Pseudophakia refers to the condition after cataract surgery when an artificial intraocular lens (IOL) has been implanted to replace the removed natural crystalline lens. The document discusses the optics and clinical symptoms of aphakia when no lens is present, as well as the types and methods of calculating the power of IOLs used in pseudophakia to restore vision. Complications like consecutive hyperopia or myopia, astigmatism, and visual issues due to the IOL like roving ring scotomas are also outlined.
