Community Based Rehabilitation: Approach to Multiple Disabilities

The previous article in this series dealt with understanding disabilities and their impact on the affected person and community. It also highlighted the modalities of rehabilitation interventions for visually disabled persons. The unique feature of CBR programmers is that the persons with Disabilities (PWDs) are identified through a Door-to-Door survey in the target area, which ensures that all such persons are identified and nobody is left out. During such surveys it is not unusual to come across persons with disabilities other than visual impairment, like those involving hearing and speech, loco motor impairments and mental retardation. Such disabilities may be present in isolation in a person or a single person may have more than one affliction. The CBR programme would cut a very sorry figure if it is unable to address the requirements of this group. Ordinarily, a CBR programme for Visually Disabled addresses this problem by coordinating with other agencies active in the area

Non surgical treatment for Keratoconus – latest advancement with eye drops

Non surgical treatment for Keratoconus – latest advancement with eye drops IVMED-80 (iVeena), which has received an orphan drug designation from the FDA. This  drug  has copper as an active ingredient, to enhance the activity of lysyl oxidase. Keratoconus occurs, Dr. Ambati explained, when there is a deficiency of natural crosslinks in the cornea, which is associated with lysyl oxidase mutations. Donor tissue that had been treated with IVMED-80 showed better stress-strain curves, Dr. Ambati said. In vivo rabbit studies with IVMED-80 showed increased ysyl oxidase activity, which he noted as biomechanical evidence of increased crosslinking. There have been no toxic or adverse events. Currently, a Phase 1/2a clinical trial in Mexico is taking place with 36 keratoconus or post-LASIK ectasia patients who take two drops a day of either vehicle or IVMED-80. The primary end-point is reduction of kmax and kmean at 6 months with a seco

A New corneal implant device useful for failed Cornea transplant

KeraKlear, invented by   Yichieh Shiuey, MD , Palo Alto, California. Since he was a resident, Dr. Shiuey said he wondered, "What if we could achieve the results of the Boston KPro without the complications and avoid the need for donor tissue?" Currently, there are limits to treating world corneal blindness, Dr. Shiuey said: lack of donor tissue, lack of trained   cornea transplant surgeons , lack of sterile operating rooms, and risk for severe complications. KeraKlear, he said, can address these issues. Seven millimetres in total diameter with a 4mm central optic, KeraKlear is implanted through a 3.5mm incision into an 8mm corneal pocket made by a femtosecond laser. It is an in-office surgery with a short learning curve with no need for combined glaucoma surgery, Dr. Shiuey said. The device is an FDA trials at four sites in patients at high risk for graft failure and aniridia keratopathy. Dr. Shiuey presented the result of a few individual cases. A patient with cornea

Endophthalmitis – eye infection IOP – eye pressure

A novel innovation to Alter the refractive index of the eye through Laser. Scott MacRae, MD, Rochester, New York, introduced laser-induced refractive index change (LIRIC, Clerio Vision) as an innovation that he said has the potential to be a better, safer way to refine optics of the eye. It could be used to revolutionize refractive surgery, provided postop IOL touch-ups and adjustments, and modify contact lenses in ways we’ve never been able to do before, he said.  Instead of altering shapes, this innovation uses a low-pulse energy femtosecond laser to modify refractive index. It can correct sphere cylinder, custom higher order aberrations, and presbyopia. The treatment, Dr. MacRae said, takes a little more than a minute. The first in-human trials with 27 monofocal, presbyopic pseudophakes were treated with a diffractive bifocal. Dr. MacRae noted clear corneas, no inflammation, no scatter, and no scarring or opacity on postop day 1 and at 1 week. Categories:   General

Glaucoma Treatment in Mumbai

A new innovation in   Glaucoma treatment . The Beacon Aqueous Microshunt (MicroOptix) –  the brainchild of David Brown, MD, 20 years in development-is 3.1 mm in length with an external flange width of 7 mm. It is implanted into a paracentesis-like incision, allowing aqueous to flow through a central channel.  Mitigation against the retrograde flow of pathogens would be a concern for such an idea. However, Dr. Riedel said that this is prevented 1 ) by shear stress and 2) by the polyethylene glycol material that composes the central layer of the three-layer device. Polyethylene glycol is considered the gold standard of anti-biofouling materials. It is super hydrophilic, and it prevents adherence of protein and bacteria to the channel wall, Dr. Riedel explained. In a porcine animal model followed to 6 months, Dr. Riedel noted no infections and significant, persistent IOP lowering. An aggressive bacterial challenge with the device on eight animals did not result in eye infection,

Oculoplasty Treatment In Mumbai

Oculoplastic Surgery is cosmetic and reconstructive procedures on the eyelids, orbit (bones and anatomic structures behind the eyeball) and lacrimal (tear drain) system. Orbit The cavity in the skull that contains the eye is called the orbit formed from parts of frontal, sphenoid, zygomatic, lachrymal, ethmoid, palatine and maxillary bones. Eye doctor plays a role in treating /managing fracture of any of these bones in case of trauma. Oculoplasty Patients of all ages may need Oculoplasty, i.e. eyelid and facial reconstructive surgery for needs purely cosmetic or purely functional. The most advanced and innovative techniques of facial and eyelid surgery for such conditions as excess upper eyelid skin that obstructs vision (blepharoplasty), eyelid ptosis(droopy eyelids), entropion(eyelids that turn in), ectropion(eyelids that turn out), problems of the tear ducts, and thyroid eye disease. Blepharoplasty A short surgery is done to remove excess upper eyelid skin hanging dow

Cosmetics that impact Dry Eye Disease

Image
Numerous beauty procedures and cosmetics applied on or near the eyes can cause or exacerbate dry eye, according to specialists, In extreme cases. These products and procedures can cause permanent damage to the ocular surface, meibomian glands, and eyelashes, so ophthalmologists need to be aware of these potential dry eye culprits, said the speakers of the instruction course on the ingredients and habits that affect dry eye disease. Both men and woman have used minerals and dyes to enhance their looks, and today they spend nearly $400 billion on cosmetics and procedures worldwide. Women do the majority of spending, and women disproportionately suffer from the ocular surface disease. Current trends in lash beauty and eyelid tattoos can impact the ocular surface, Lash extensions, false lashes, and lash embellishments can all damage the natural eyelashes even when done properly, Lashes naturally protect the corneal surface from pollutants and debris, but lash extensions can actuall

What is Cataract

Image
Like a camera, the eye sees when light enters it. Inside your eye is a natural clear lens, much like the lens of a camera. It focuses the light rays coming through the pupil onto the retina at the back of the eye. The different parts of the retina collect this light and send a message to your brain, enabling you to see. For perfect vision, the lens should be clear so that light can pass through it. Light enters through the cornea, passes through your natural lens and is focused onto your retina, resulting in clear vision When the lens becomes cloudy or opaque, light cannot pass through it. A cataract scatters the light rays passing through the eye, thus resulting in blurred vision. A cataract is a condition when the natural lens inside your eyes gets cloudy. Compared to vision with a clear lens, your vision with a cataract may look fuzzy, colors might be muted, and you may experience difficulty in reading signs while driving at night. The symptoms of cataracts are progressive a

Dry Eye Treatment

Dry eye syndrome or Keratoconjunctivitis sicca (KCS), is a frequently encountered ocular problem.   Dry eye syndrome   is a clinical condition characterized by deficient tear production or excessive tear evaporation resulting in ocular discomfort. In addition to the term dry eye, which is now established worldwide, the specific term “ ocular surface and tear disorder ” has been suggested by Tseng and Tsubota. High Risk Population for Dry Eye Disease Advanced age and female gender. Inflammatory disease (vascular, allergy, asthma) Autoimmune diseases (RA, Lupus, colitis) Peri and post menopausal women and Hormone Replacement Therapy patients. Diabetes Mellitus. Thyroid disease. Corneal transplantation Previous keratitis or corneal scarring Extra capsular or intracapsular large- incision   cataract surgery . Laser in situ keratomileusis (LASIK) Systemic medications (diuretics, antihistamines, psychotropics, cholesterol-lowering agents) Contact lens wear Environmental

Retina Treatment In Mumbai

Image
Retina is like the film in a camera. Retina is the third and inner coat of the eye which is a light-sensitive layer of tissue. When the focused light hits the retina, a picture is created and sent to the brain through the optic nerve (the nerve of the eye), thus giving us vision. Sometimes part of the retina either tears, pulls away or detaches from the back of the eye; when this occurs that part of the retina cannot gather light ans results in vision loss. Diseases and conditions of the retina Age-Related Macular Degeneration Diabetic Retinopathy Retinal tear Retinal Detachment Age-Related Macular Degeneration What causes in AMD? During normal aging, yellowish deposits, called drusen, form under the retina, which is the light-sensitive layer of tissue at the back of the eye that provides clear, sharp images. As drusen increase in size and number, they can interfere with proper functioning of the retina, damaging or killing the light-sensitive cells of the macul
