Basics of pediatric refraction by dr.adnanMahamudAdnan
油
This document summarizes the basics of pediatric refraction as presented by Dr. Mahamud Adnan. Key points include:
1) Pediatric refraction requires great expertise as it is different from normal refraction due to active accommodation in children. Cycloplegic refraction is preferable to paralyze the ciliary muscles.
2) The refractive status of infants and children changes rapidly in the first year as visual development occurs. Cycloplegia allows determining the true refractive error without accommodation.
3) Cycloplegic drugs like atropine and cyclopentolate are used which have side effects like blurred vision but allow full paralysis of accommodation for accurate refraction assessment. Timely intervention andSensory evaluation of squint

This document provides guidelines for prescribing glasses in children. It discusses that the pediatric eye is different from the adult eye in terms of axial length, corneal curvature, and lens power. The goals of prescribing glasses in children are to provide a focused retinal image and achieve optimal balance between accommodation and convergence. It is more difficult to prescribe glasses for children due to lack of subjective response and poor attention. American guidelines provide recommendations on refractive errors that warrant correction at different ages. Factors like emmetropization, amblyopia risk, and presence of strabismus are considered. Frame selection depends on the child's condition and age, aiming for correct fit, comfort, safety, and not hindering nasal development.Soft contact lens complications
Soft contact lens complicationsMd Riyaj Ali
油
Soft contact lens complications can include ocular discomfort, inflammation, infection, and other issues. Ocular discomfort is the most common complication and has many potential causes, both physical and physiological. Inflammation like bulbar redness, corneal infiltrates, and contact lens peripheral ulcers can occur due to factors like tight lenses, deposits, hypoxia, or infection. Proper lens care and frequent replacement are important to prevent complications, along with addressing any underlying causes like dryness or infection. Complications generally require discontinuing lens wear until signs and symptoms resolve. Non Surgical Treatment of Strabismus

Duane's retraction syndrome involves congenital miswiring of the medial and lateral rectus muscles, causing limited eye movement. There are typically four types based on the pattern of limited adduction and/or abduction. Treatment may involve glasses, prisms, botulinum toxin injections, or surgery such as recession of the medial or lateral rectus muscles to improve eye alignment and positioning. Brown syndrome similarly involves a congenital or acquired restriction of eye elevation in adduction, believed to be caused by an abnormality of the superior oblique tendon. It is characterized by limited elevation in adduction and downshoot, and may cause a vertical eye misalignment.Fitting Philosophies and Assessment of Spherical RGP lenses

Dynamic retinoscopy srijanaSrijana Lamichhane
油
Dynamic retinoscopy is used to objectively determine a patient's refractive error when their accommodation is active. It involves having the patient fixate on a near target while the examiner performs retinoscopy. The direction of the retinoscopic reflex indicates whether the eye is focused in front of, behind, or aligned with the retinoscope. Various methods of dynamic retinoscopy have been developed, including Monocular Estimation Method, Bell retinoscopy, and Nott retinoscopy. Dynamic retinoscopy can reveal a patient's lag of accommodation, or the difference between their accommodative response and the stimulus provided by the near target. A normal lag is between +0.50D to +0.75D.Presbyopia
PresbyopiaDr Rakhi Dcruz
油
Presbyopia is the physiological loss of accommodation that occurs with aging, usually starting around ages 40-45. It is caused by age-related hardening of the lens and a decline in the ciliary muscle's ability to change the lens shape. Symptoms include difficulty with near vision and asthenopia. Treatment involves using convex lenses matched to the patient's age to supplement the lost accommodation, with options including reading glasses, bifocals, trifocals, and multifocals. Surgical options also exist such as conductive keratoplasty or presbyopic laser procedures.Testing for npa

This document describes how to test for the near point of accommodation (NPA) and near point of convergence (NPC). For NPA testing, the examiner places a near testing card at 16 inches from the patient's eye and moves it closer until the letters blur, recording the distance. This is repeated for each eye. For NPC testing, the examiner holds a target at 16 inches from the patient and moves it closer until the image doubles or one eye deviates, recording the distance from the nose. Both tests measure the closest point an image can remain clear and single.Rgp lens

Rigid gas permeable (RGP) contact lenses are rigid plastic lenses that transmit oxygen. They have inherent rigidity like PMMA but are semi-soft due to oxygen permeability. RGP lenses provide clearer vision than soft lenses, are more durable, and less expensive. However, they require an adaptation period and have a higher risk of dislodging than soft lenses. Key design features of RGP lenses include the back surface design, thickness, edge configuration, and diameter, which affect lens fit, movement, comfort, and vision. RGP lenses are used to correct astigmatism and presbyopia and for conditions like keratoconus.Hess chart, diplopia chart, cover tests

This document discusses various tests used to evaluate binocular vision, including cover tests, Hess charting, and diplopia charting. Cover tests are used to detect manifest or latent strabismus and determine deviation direction. Hess charting maps eye positions in 9 gazes using colored lenses to dissociate vision between eyes. It identifies muscle under or overaction. Diplopia charting records double vision separation in 9 gazes to localize affected muscles. These objective tests evaluate binocular function and strabismus type and localization.Aniseikonia 
Aniseikonia Azizul Islam
油
The term aniseikonia comes from the Greek words an (not) is (equal) & eikon (icon or image) so aniseikonia is a binocular condition in which the apparent sizes of the images seen with the two eyes are unequal.
Whenever refractive ametropias in the two eyes of a person are different (i.e., when there is an anisometropia), the corrected retinal images of the two eyes, and consequently the two visual images, differ in size.
This condition has been termed aniseikonia

Heterophoria and HeterotropiaMero Eye

Heterophoria and heterotropia refer to relative and manifest deviations of the visual axes. Statement b is wrong - in heterophoria, motor fusion is adequate to maintain alignment only when viewing with both eyes, not in higher degrees of heterophoria where suppression and high stereoscopic thresholds may be present. The most common type of phoria associated with uncorrected hyperopia is exophoria. Exophoria is also more common in hypermetropia. Oculomotor nerve palsy may be congenital, causes pupil involvement suggesting a medical cause, and warrants neuro-radiological investigation rather than just laser treatment.MCQ of ophthalmology(eyelids)

The document provides information about anatomy and disorders of the eyelid:
- The eyelids perform the important function of spreading tears over the cornea. The palpebral aperture is the space between the upper and lower lids. The lid margin helps in drainage of tears via the lacrimal pump system.
- Disorders mentioned include blepharitis, styes, entropion, ectropion, and tumors. Bacterial blepharitis is caused by Staphylococci and can cause ulcers and redness of the lid margin. Tumors include benign papillomas and malignant carcinomas such as basal cell carcinoma and sebaceous gland carcinoma.

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.Optics of vision bcqs
