This study analyzed clinical data from 108 children undergoing overnight orthokeratology treatment at a university clinic in Hong Kong. Significant reductions in spherical refractive error (58%) and improvements in unaided vision were found after just one night of lens wear. Over 80% of patients were advised to use eye drops to help remove the lenses, as corneal staining was a common complication. A patient survey found that over 90% reported good or better unaided vision after treatment and rated it as satisfactory or very good, though lens binding and eye discharge were commonly reported problems. The results suggest that overnight orthokeratology is effective and safe for reducing low to moderate myopia in children under close monitoring.

Objectives: The aim of this study was to compare sonoelastographic findings in the retina– choroid–sclera (RCS) complex and vitreous in glaucomatous and healthy eyes.Methods: For this cross-sectional comparative study, 20 patients with primary open-angle glaucoma (POAG) and 20 healthy volunteers were recruited. Ultrasound elastography measurements were taken with a sonographic scanner of the RCS complex, anterior vitreous (AV), posterior vitreous (PV), retrobulbar fat tissue (RFT), optic disc, and optic nerve in each eye.Results: The elasticity index of the RCS complex, RFT, optic disc, optic nerve, AV, and PV were similar in both groups (p > 0.05), though the AV/PV strain ratio in the group of patients with glaucoma was significantly higher (p = 0.04).Conclusion: Glaucoma increases the AV/PV strain ratio. In providing reproducible and consistent values, the real-time elastography technique may be helpful in elucidating the mechanisms of glaucoma in some aspects.
This document presents the final results of the Early Treatment for Retinopathy of Prematurity (ETROP) randomized trial. The trial compared early retinal ablative treatment to conventional management for infants with high-risk prethreshold retinopathy of prematurity (ROP). The study found that early treatment significantly reduced unfavorable outcomes, with a reduction in unfavorable visual acuity from 19.8% to 14.3% and unfavorable structural outcomes from 15.6% to 9.0%. The results support retinal ablative therapy for type I ROP and a "wait and watch" approach for type II ROP.

Restoration of visual acuity with #Isotine eye drops - An Ayurvedic formulati...Mandeep Basu
Approximately 8 million to 2.3 million people worldwide have impaired vision due to uncorrected refractive error and cataract1. Hence the World Health Organization (WHO) has initiated Vision 2020 global program – “The right to sight”. The main motto of Vision 2020 is to correct refractive errors. The author after years of trial and error has formulated unique Ayurvedic eye drops “ISOTINE”. This has a very precise and balanced combination of Ayurved content that not only corrects the refractive errors but also visual acuity and subjective symptoms.
This study used MRI to assess optic nerve degeneration in a monkey model of experimental glaucoma induced by laser photocoagulation. MRI was performed on 8 monkeys approximately 2 years after laser treatment to one eye. Diffusion tensor imaging parameters including axial and radial diffusivity, fractional anisotropy, and apparent diffusion coefficient were analyzed in the optic nerves and correlated with intraocular pressure measurements. Results showed that as intraocular pressure increased, optic nerve cross-sectional area decreased and diffusivity parameters increased linearly while fractional anisotropy decreased linearly, indicating optic nerve degeneration correlated with elevated intraocular pressure. This study demonstrates MRI can quantify in vivo optic nerve degeneration related to glaucoma and may be useful for evaluating potential therapies.
This study measured binocular balance in people with normal vision by quantifying their sensitivity to coherent motion presented separately to each eye. The study found that:
1) Most subjects showed balanced or weakly imbalanced sensitivity between the eyes, but some showed strong imbalances.
2) The degree of imbalance, or "balance point", was affected by mismatches in mean luminance between the eyes, suggesting inhibitory circuits underlying eye dominance are located precortically.
3) Changing the interocular contrast ratio allowed quantification of the contrast required for balanced sensitivity, referred to as the balance point.
This document summarizes a study that assessed changes in nearwork-induced transient myopia (NITM) parameters and accommodative functions after 6 weeks of home-based accommodative training in 10 young adult progressing myopes. The study found that after training, several dynamic accommodative response functions improved significantly, including increased lens flipper and Hart chart rates. There was also a significant negative correlation between lens flipper rate and NITM decay duration, indicating faster decay. The training resulted in improved accommodative dynamics and a reduction in NITM, consistent with previous reports of improvement in symptomatic myopes with vision therapy.
Orthoptic evaluation examines eye alignment, eye movement, and binocularity using various tools. It involves assessing convergence, accommodation, and binocular single vision. Clinical signs of convergence and accommodation dysfunction include diplopia, headaches, and blurred vision. Treatment may include prism exercises, accommodative therapy, and vision therapy. The orthoptist plays a key role in diagnosing and providing non-surgical treatment for conditions like amblyopia and strabismus.

Orthoptic evaluation examines eye alignment, eye movement, and binocularity using various tools. It involves assessing convergence, accommodation, and binocular single vision. Clinical signs of convergence and accommodation dysfunction include diplopia, headaches, and blurred vision. Treatment may include prism exercises, accommodative therapy, and vision therapy. The orthoptist plays a key role in diagnosing and providing non-surgical treatment for conditions like amblyopia and strabismus.
An orthoptic evaluation systematically evaluates the function of eye muscles during binocular eye movements to maintain fusion. It identifies accommodative, vergence, or fusional vergence anomalies to guide orthoptic exercises for treatment. The evaluation includes tests to check for single vision, diplopia, suppression, alignment, and accommodation. Based on symptoms like headaches or blurry vision, further tests are done to diagnose conditions like convergence insufficiency. The evaluation involves tests of phoria, near point of convergence, accommodation, fusional vergence, and accommodative function and facility.
This study examined the correlation between central corneal thickness (CCT) and results from Frequency Doubling Technology Perimetry (FDT) in 180 patients aged 40 or older with high intraocular pressure (IOP) but normal optic discs. The average CCT across both eyes was 531 microns. Abnormal FDT results were found in 18 subjects, who had thinner average CCT of 519 microns, compared to 532 microns in 162 subjects with normal FDT results. The study concludes that among patients with high IOP but normal discs, thicker corneas are associated with a lower risk of early glaucomatous damage detected by FDT, compared to patients with thinner corneas.

The document provides information on evaluating cases of orthoptics. It discusses evaluating a patient's history, visual acuity, eye movements, sensory status, and degree of strabismus. The evaluation includes assessing visual acuity, refraction, eye alignment using various objective tests like cover tests, assessing binocularity using stereopsis tests, and determining the presence of suppression or abnormal retinal correspondence. The document outlines the various tests used to evaluate motor and sensory functions in patients with strabismus.
This study analyzed the relationship between binocular vision, visual acuity, and fine motor skills in 121 subjects aged 12-28 years. The subjects performed pegboard, bead threading, and water pouring tasks. Performance on the tasks was significantly better in subjects with sensory and motor fusion compared to those without for most tasks. Both the visual acuity in the poorer seeing eye and the difference in acuity between eyes were significantly related to performance, with higher acuity relating to better performance. The results suggest that both good binocular vision and visual acuity can benefit fine motor skill performance.
This document discusses the interface between optometry and ophthalmology regarding optometric vision therapy. It provides historical context on the evolution of orthoptics to vision therapy. It notes that while ophthalmologists pioneered orthoptics, optometrists were better suited to provide the intensive therapy it required. It also discusses ophthalmology's initiatives to discredit vision therapy through policy statements that optometry has rebutted with scholarly articles. The document aims to provide a balanced perspective to improve the interface between the two fields in serving the public.
This case report describes a 26-year-old woman who experienced a spasm of the near reflex (accommodation, convergence, and miosis) when either eye was occluded or subjected to dioptric or non-dioptric blur. Her visual acuity decreased dramatically and an esodeviation was observed when either eye was occluded. Various occluders and lenses were able to trigger the spasm when a specific threshold of visual disruption was reached for each stimulus. Cycloplegia did not eliminate the spasm. This appears to be a rare case of a functional spasm of the near reflex triggered by binocular vision disruption, suggesting a potential anomaly in the neurological pathways involved in the
This document provides an overview of assessing strabismus in children. It discusses classifying strabismus based on age, taking a thorough patient history, performing a visual assessment including visual acuity and binocularity tests, and conducting a sensory and motor assessment of eye alignment and eye movement. The motor assessment involves tests like cover testing, versions, ductions, and special tests like vestibular eye movements. Taking this comprehensive approach allows for correctly diagnosing the type and extent of strabismus and determining appropriate management options.
The synaptophore is an orthoptic instrument used for both diagnostic and therapeutic purposes in optometry. It works using the haploscopic principle to divide visual space into two separate areas visible to only one eye each. Slides can be used for simultaneous perception, fusion, stereopsis, and other tests. Diagnostic uses include measuring deviations, retinal correspondence, and fusional reserves. Therapeutic uses treat suppression, amblyopia, and heterophorias. Proper adjustment and preliminary settings are required before administering tests to accurately diagnose and manage binocular vision anomalies.
Reduction of retinal senstivity in eyes with reticular pseudodrusenAbdallah Ellabban
This study evaluated the effect of reticular pseudodrusen on retinal function using multiple imaging methods in 13 eyes with reticular pseudodrusen but no other macular abnormalities. Infrared reflectance imaging detected reticular pseudodrusen within the central macula in more eyes than color fundus photography or fundus autofluorescence. Retinal sensitivity across the macula was lower in eyes with reticular pseudodrusen compared to normal eyes. The number of reticular pseudodrusen detected by different imaging modalities correlated with reduced retinal sensitivity in specific macular areas.
This document summarizes a journal club presentation on a study investigating the safety and efficacy of lower doses (0.01%, 0.1%, and 0.5%) of atropine for treating childhood myopia. The study involved 400 children aged 6-12 years with myopia who were randomized to receive one of the three atropine doses nightly for 2 years. Results showed a dose-dependent response, with the 0.5% dose slowing myopia progression the most but also causing more side effects like diminished accommodation and larger pupils. The 0.01% dose had the smallest effect on slowing progression but caused minimal side effects. Overall, lower doses of atropine showed potential as an alternative treatment with fewer visual side
Prince investigation in paralytic strabismusPrinceRajavat
This document discusses paralytic strabismus, which is an incomitant strabismus where the eye deviation is different when measuring with the paretic versus non-paretic eye fixing. It outlines the tests used to investigate paralytic strabismus, including history taking, visual acuity assessment, identification of squint with tests like cover test and Hirschberg test, measurement of deviation with prism bar cover test, and confirmation tests like forced duction testing and three step testing to determine the affected extraocular muscle. References are provided for further reading on clinical examination and management of paralytic strabismus.
Vision therapy is an individualized treatment program designed to correct visual and perceptual deficiencies and improve vision skills through activities like eye tracking and coordination exercises. It can help with conditions like amblyopia, strabismus, and convergence insufficiency by strengthening the visual system and improving connections in the brain. Research studies have found vision therapy to be an effective treatment for improving visual acuity and stereopsis in patients with refractive amblyopia and for establishing sensory fusion in patients with strabismus.

This study investigated the effect of under-correcting myopia on myopic progression by analyzing clinical refraction data from 275 visits of 76 myopic patients. The results showed a significant positive correlation between the degree of under-correction and myopic progression, with greater under-correction associated with greater progression. Myopic progression also correlated positively with the degree of myopia. However, progression did not correlate with age or gender. The findings suggest that under-correcting myopia may induce small increases in myopic progression compared to full correction.
- An article describes what is the impact of refractive error on a layer of retina ( nerve fiber layer) in myopic subjects, Download its full text from Isra Medical Journal.
Objective: To evaluate myopic impact on thickness of nerve fiber layer of the retina in healthy myopic subjects.
Study Design: Prospective Observational study.
Place and Duration: Investigative Department of Ophthalmology of Al-Ibrahim Eye Hospital, Karachi from 1st May 2018 to 30th October 2018.
Methodology: In this study 80 eyes of myopic subjects (SE -0.5 to -11.0 DS) were enrolled. Each eye underwent through comprehensive ocular examination beginning with visual acuity, refraction, fundoscopy by slit lamp and ending up to optical coherence tomography of Nidek. Mean average peripapillary thickness of nerve fiber layer and thickness in superior, inferior, nasal and temporal quadrants was taken into consideration, calculated by Spectral Domain Optical Coherence Tomography (version 1.5.5.0).
Results: Forty subjects volunteered for study protocol among which 21 were male and 19 were female with a degree of refractive breakdown of 30% mild myopic, 50% moderately myopic and 20% highly myopic. The calculated average age was 25.0 ± 5.0 years (range 16-40 years). The average total nerve fiber layer thickness in myopic respondents was 90.85μm; superiorly 112.37μm; inferiorly 117.52μm; temporally 71.85μm and in nasal quadrant was 61.55μm. Retinal nerve fiber layer thickness was statistically significant in superior and temporal quadrant. In high myopes thickness was clinically significant in inferior quadrant in terms of quantity as compared to mild and moderate myopia
Conclusion: Average retinal nerve fiber layer thickness was significantly decreased in high myopia as compared to mild myopia while moderate group had slightly thicker thickness than high myopic group. Hence impact of dioptric power on nerve fiber layer thickness in myopic patients is significant.
This study compared visual outcomes after cataract surgery using femtosecond laser-assisted cataract surgery (FLACS) versus conventional phacoemulsification (CPS) with implantation of an extended depth of focus (EDOF) intraocular lens (IOL). The study found that FLACS produced significantly less IOL decentration and tilt, lower wavefront aberrations, better contrast sensitivity, and fewer visual disturbances reported by patients. Therefore, FLACS may provide improved visual performance compared to CPS when using an EDOF IOL by achieving a more precisely centered IOL position. The study provides evidence that lens positioning is an important factor for optimal visual outcomes with EDOF IOLs.
This study evaluated the reliability of clinically assessing limbal ischemia among 111 ophthalmic professionals by having them review color slit-lamp photographs of eyes with chemical injuries. The professionals showed poor agreement in identifying the presence, location, and grade of limbal ischemia. Consultants showed the highest but still poor agreement, while optometrists showed the lowest agreement. The results suggest the clinical assessment of limbal ischemia is unreliable and inconsistent, even among experienced professionals. Standardized criteria are needed to properly diagnose and manage limbal ischemia in ocular burns.

To investigate an outcome of dynamic and log mar visual acuity on cataract pa...KrishnaKumarGupta26
This document discusses a study investigating the outcomes of dynamic and logMAR visual acuity testing on cataract patients. The study aims to measure logMAR visual acuity and dynamic visual acuity using a DYOP chart on cataract patients. A literature review is presented covering previous research demonstrating differences between static and dynamic visual acuity and the impact of factors like neck muscle fatigue and vestibular dysfunction on dynamic visual acuity. The need for the study is that static acuity tests do not accurately measure visual acuity in dynamic real-world conditions, whereas the DYOP chart provides a faster dynamic assessment.
Myopic shift and preoperative axial length after congenital cataract surgery in Peruvian patients - The Association for Research in Vision and Ophthalmology Meeting (ARVO) 2018 Honolulu, Hawaii - Poster presentation
This randomized clinical trial compared the effectiveness of vision therapy/orthoptics, pencil pushups, and placebo vision therapy/orthoptics for treating convergence insufficiency in adults aged 19-30. 46 patients were randomly assigned to receive one of the three treatments for 12 weeks. Vision therapy/orthoptics was the only treatment that significantly improved near point of convergence and positive fusional vergence. However, over half of patients receiving vision therapy were still symptomatic at the end of treatment, though symptoms were reduced. All three groups experienced statistically significant reductions in symptoms, with 42% of vision therapy patients, 31% of placebo patients, and 20% of pencil pushup patients achieving elimination of symptoms.

5-hydroxytryptamine or 5-HT or Serotonin is a neurotransmitter that serves a range of roles in the human body. It is sometimes referred to as the happy chemical since it promotes overall well-being and happiness.
It is mostly found in the brain, intestines, and blood platelets.
5-HT is utilised to transport messages between nerve cells, is known to be involved in smooth muscle contraction, and adds to overall well-being and pleasure, among other benefits. 5-HT regulates the body's sleep-wake cycles and internal clock by acting as a precursor to melatonin.
It is hypothesised to regulate hunger, emotions, motor, cognitive, and autonomic processes.

8 Surprising Reasons To Meditate 40 Minutes A Day That Can Change Your Life.pptxHolistified Wellness
We’re talking about Vedic Meditation, a form of meditation that has been around for at least 5,000 years. Back then, the people who lived in the Indus Valley, now known as India and Pakistan, practised meditation as a fundamental part of daily life. This knowledge that has given us yoga and Ayurveda, was known as Veda, hence the name Vedic. And though there are some written records, the practice has been passed down verbally from generation to generation.
