This document discusses the ABCD staging system for diagnosing and monitoring progression of keratoconus. It begins with an overview of keratoconus and the need for early diagnosis and treatment. It then reviews prior classification and progression monitoring systems. The document introduces the Belin ABCD staging system, which uses tomographic pachymetry maps to assess four parameters (A= maximum keratometry, B= minimum keratometry, C= thickness, D= asymmetry) and stage disease. It presents evidence that the ABCD system can identify progressive keratoconus an average of 5 months earlier than prior methods, allowing for earlier intervention like corneal collagen cross-linking. The conclusion is that the ABCD system allows earlier diagnosis
This document summarizes the current treatment options, outcomes, and controversies regarding refractive surgery in children. It reviews literature on various refractive surgery techniques like LASIK and PRK. While small studies show promise, there is no long-term data from large controlled trials. Key issues include risks of regression, flap complications, the impact of amblyopia on vision, and unknowns around healing in children. More research is still needed before refractive surgery can be considered routine for pediatric patients.

3D Tomgraphic features in dome shaped macula by swept source OCTAbdallah Ellabban
This study used swept-source optical coherence tomography (OCT) to examine the 3D tomographic features of dome-shaped maculas in highly myopic eyes. OCT imaging revealed that in all eyes, the retinal pigment epithelium within the posterior staphyloma had two outward concavities separated by a horizontal ridge. In most eyes the ridge was band-shaped. The study provides new insights into the topography and underlying pathomorphology of dome-shaped maculas.

Michael Duplessie -Keratorefractive & lenticular surgeryMichael Duplessie
This document discusses various procedures for keratorefractive and lenticular surgery, including indications, clinical evaluation, and techniques. It covers cataract surgery and techniques to correct astigmatism like relaxing incisions and toric intraocular lenses. It also discusses complications like endophthalmitis and toxic anterior segment syndrome. Excimer laser procedures like phototherapeutic keratectomy are described. Piggyback intraocular lenses to correct refractive errors and phakic intraocular lenses are also summarized.
The document discusses using high frequency ultrasound (UBM) to accurately measure the ciliary sulcus dimensions for sizing phakic intraocular lenses (ICL). Previous sizing methods based on white-to-white measurements were found to be inaccurate. A multi-center study demonstrated superior vault outcomes using a nomogram based on ciliary sulcus measurements from UBM imaging compared to white-to-white. Adopting ciliary sulcus sizing with UBM could eliminate sizing mismatches and reduce risks of complications.
This study evaluated the long-term efficacy, safety, and stability of posterior chamber phakic intraocular lens (ICL) implantation for correction of high ametropia. The study retrospectively reviewed 90 eyes of 53 patients with high myopia, hyperopia, or astigmatism who underwent ICL implantation with a mean follow-up of 5 years. Results showed that ICL implantation effectively corrected refractive error and achieved good visual acuity outcomes. Post-implantation, endothelial cell density decreased stable at 0.69% per year and few eyes developed lens opacity. Overall patient satisfaction was high, demonstrating that ICL implantation is an effective option for correcting high ametropia with a favorable long-term safety
Michael Duplessie Eye Department, Eye surgery and eye careMichael Duplessie
This document discusses various eye conditions and treatments. It covers reasons for eye exams, common eye diseases like glaucoma and cataracts. It also discusses various surgical procedures like cataract surgery, corneal transplants, and presbyopia correcting lenses. Laser vision correction techniques like LASIK, SMILE, and lens implants are explained. Conditions like keratoconus and corneal scarring are mentioned.
This study prospectively examined 35 eyes with dome-shaped macular configuration using swept-source optical coherence tomography over a mean follow-up period of 24.8 months. The study found progressive asymmetric thinning of the sclera in the macular region. Scleral thinning was more pronounced in the parafoveal area than at the foveal center, resulting in an increase in macular bulge height over time. The choroid also showed generalized thinning within the staphyloma during follow-up. The ocular concavities deepened and macular bulge height increased significantly, indicating the progressive nature of the posterior pole changes in eyes with dome-shaped macular configuration.
This document discusses surgical techniques for treating retinal detachment in highly myopic eyes, specifically posterior buckling procedures. It describes the pathogenesis of retinal detachment in high myopia, which is often caused by persistent adherence of rigid epiretinal tissue and retinal/choroidal defects in the staphyloma area. Both posterior buckling and vitrectomy are discussed as surgical options, with buckling recommended for cases with severe staphylomas, pronounced retinal schisis, or when epiretinal membranes cannot be easily cleaved from the retina during vitrectomy. The posterior buckling procedure and silicone buckle element are described in detail. In conclusions, vitrectomy is primarily recommended but buckling may be useful as

It is also noted as having a stable working height and only requiring the lens holder and lenses to be sterilized.
A patient education lecture explaining modern catract surgery solutions. Cataract surgery these days not only removes your glasses but can correct other preexisting errors as well. Toric and multifocal IOLs have opened new windows for visual rehabilitation after cataract surgery.
A cataract is a cloudy area in the lens of the eye that can cause blurred or dim vision. It is the leading cause of blindness worldwide and a common cause of vision impairment in the United States. Cataracts develop due to aging, sun exposure, smoking, poor nutrition, eye trauma, certain diseases, and some medications. Diagnosis involves an eye exam using a slit lamp microscope. Treatment is typically cataract surgery to remove the cloudy lens and replace it with an artificial intraocular lens. The decision for surgery depends on the degree of vision impairment and its impact on quality of life. Modern cataract surgery is a low risk outpatient procedure with rapid recovery of clear vision.
This document discusses the MINIFLEX TORIC intraocular lens. It provides details on the material, design features, and benefits of this toric IOL. Key points include its aspheric optic design, 1.8mm injection system allowing microincision cataract surgery, self-centering haptics for stability, and 360 degree squared edge to prevent posterior capsule opacification. The document also outlines patient selection criteria, pre-operative techniques including online calculators, and checking the IOL axis immediately after surgery to ensure proper alignment.
Retropupillary fixation of iris claw iol in phaco complicationedmond Isufaj
This document summarizes a study on the long term results of using an iris-claw intraocular lens (ICIOL) to manage complications during cataract surgery. The study followed 21 eyes of 20 patients over 1-4 years after an ICIOL was implanted during complications including posterior capsule rupture and zonular dehiscence. The results found that the ICIOL position remained stable in all cases, with 71.4% achieving good vision. However, some patients reported issues like glare or pupil deformation. Overall, the study concluded that retropupillary fixation of an ICIOL is an effective technique for managing complications during cataract surgery.
This document discusses reasons for failure in macular hole surgery and tips to avoid failures. It identifies common primary failure rates of 2-15% and notes that the actual failure rate is likely higher since not all patients with failed surgery elect to undergo reoperation. Anatomical reasons for failure include hole size greater than 800 microns and duration of symptoms over 2 years. Surgical reasons include failed release of tractions, failed tamponade allowing fluid to enter the hole, and residual vitreous gel/hyaluronic acid dropping into the hole. Tips to improve success rates include techniques to remove the internal limiting membrane and avoid fluid exchange over the hole.
Optical coherence tomography angiography optovue a very basic lecture detailing the new advancement of dyeless angiography by spectral domain OCT system and SSADA and Motion correction algorithm
This document compares various cataract surgical techniques from ancient to modern times. It describes the evolution of techniques from couching and needling without anesthesia to current phacoemulsification with foldable intraocular lenses. Each new technique brought improvements such as more precise surgery, reduced complications, and less induced astigmatism. The latest techniques allow for small incisions, use of viscoelastic aids, chamber stability, and precision in nucleus management. The document encourages tailoring the surgical approach individually based on each case's specific merits rather than a one-size-fits-all method.

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.
