OCT allows for high-resolution cross-sectional imaging of the retina. It provides micron-level resolution, enabling visualization of the retinal layers. OCT is a non-contact, non-invasive technique useful for qualitative and quantitative analysis of the retina and monitoring of morphological changes. It can detect and measure retinal thickness, volume, and parameters like RNFL thickness. While it provides advantages over other modalities, OCT also has limitations like difficulty imaging through opaque media. It operates using low-coherence interferometry and is useful for evaluating a variety of posterior segment diseases.
Neovascular glaucoma is a severe form of glaucoma caused by the formation of abnormal blood vessels in the eye. It is usually associated with retinal ischemia or lack of oxygen to the retina from conditions like diabetic retinopathy or central retinal vein occlusion. The abnormal blood vessels can grow on the iris, angle, and anterior chamber and obstruct the outflow of aqueous humor, leading to increased eye pressure and glaucoma. The main treatment is panretinal photocoagulation to reduce retinal ischemia and prevent further neovascularization, along with glaucoma medications or surgery to lower eye pressure. Anti-VEGF drugs may also help reduce the abnormal blood vessels. Without treatment, it can progress to severe vision

Looking deep into retina : indirect ophthalmoscopy and fundus drawingPrachir Agarwal
Indirect ophthalmoscopy provides a panoramic view of the fundus and is essential for a complete examination. It works by forming an aerial image of the retina between the condensing lens and observer. The power of the condensing lens determines the working distance, magnification, and field of view. Indirect ophthalmoscopy has advantages over direct including an unaffected view by refractive error and better illumination, resolution, and peripheral visualization. Proper technique involves adjusting the device, positioning the patient, and using scleral depression for stereoscopic viewing. Fundus drawings document examination findings and utilize various colors and line styles to depict different retinal structures and pathologies.
This document describes a case study of a limbal dermoid, a benign congenital tumor containing abnormal tissue found at the cornea. It summarizes the presentation, examination, and surgical removal of a limbal dermoid in a 30-year-old male patient. The dermoid was removed through local anesthesia and histopathological examination confirmed the diagnosis. While the surgery improved symptoms, there was little change in vision due to preexisting amblyopia and astigmatism. Limbal dermoids are generally classified based on their size and depth of involvement in the eye. Surgical techniques range from simple excision to more extensive procedures depending on the grade of the dermoid.
VEGF is a growth factor that promotes abnormal blood vessel growth in the retina and causes vision loss. Anti-VEGF drugs like ranibizumab (Lucentis), bevacizumab (Avastin), and pegaptanib (Macugen) work by blocking VEGF and stopping this blood vessel growth. Ranibizumab was designed specifically for eye injections and has a short half-life, while bevacizumab was designed for cancer but is also used "off-label" in the eye. Clinical trials found that both drugs are effective in treating wet AMD, diabetic retinopathy, and other retinal diseases, but ranibizumab may have a slightly lower risk of rare side effects due to its shorter exposure in

These tools are used to fully examine patients and correctly diagnose and treat refractive errors and other eye conditions.
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.
This document summarizes a presentation on esodeviations (convergent strabismus). It discusses various types of esotropia including infantile, accommodative, acquired non-accommodative, and incomitant esotropia. Infantile esotropia presents in the first 6 months of life and requires early surgery. Accommodative esotropia is associated with hyperopia and convergence accommodation. Acquired non-accommodative esotropia develops after 6 months without hyperopia. Incomitant esotropia involves limitations in eye movement. Treatment depends on the type but may include glasses, patching, prisms, botulinum toxin injections, or strabismus surgery
Glaucoma drainage devices (GDDs) provide an alternative pathway for aqueous humor outflow and are used to treat refractory glaucoma. The document discusses the history, design, and types of various GDDs including non-valved devices like Baerveldt and Molteno implants as well as valved devices like the Ahmed Glaucoma Valve. The key components, materials, and surgical techniques for GDD implantation are also summarized.
This document discusses corneal collagen cross linking (C3R), a treatment for keratoconus. It begins by describing keratoconus and its symptoms. It then discusses the original C3R protocol developed by Seiler and Spoerl, which involves removing the corneal epithelium, soaking the cornea in riboflavin, and exposing it to UV light. Modifications to the protocol aim to reduce complications by using higher irradiance for less time, different riboflavin delivery methods, and leaving the epithelium intact. Studies show C3R increases corneal collagen bonds and rigidity while halting keratoconus progression in most cases. Contraindications and post-op care are also outlined

IOL implantation in the absence of capsular bagcrisnemato
This document discusses options for intraocular lens (IOL) implantation when the eye's natural capsular support is absent. It reviews causes of ectopia lentis and traumatic/surgical aphakia. Three main IOL options are described: scleral fixation, iris-claw fixation, and iris suturing of the IOL. Each option is evaluated based on surgical techniques, published studies, outcomes, complications, and patient factors. The document concludes by proposing protocols for IOL implantation based on individual patient and ocular characteristics to provide the best visual outcomes while minimizing risks of complications requiring long-term follow-up.
Wide angle viewing field systems in vr surgerySamuel Ponraj
Wide angle viewing systems provide panoramic views of the retina during vitreous surgery. There are contact and non-contact systems. Contact systems include vitreous panfundoscopes, contact wide field lenses, advanced visual instrument systems, and reinverting operating lens systems. These provide good image resolution but require an inverter due to the inverted image and have risks of corneal trauma. Non-contact systems like the BIOM and Resight provide upright images without inversion but have poorer image quality. Newer non-contact systems aim to provide wide fields of view with upright high resolution images.
Glaucoma is a chronic optic neuropathy and a leading cause of blindness worldwide. Structural changes to the optic disc can be detected earlier than functional vision loss, so assessing the disc is crucial. The Disc Damage Likelihood Scale (DDLS) was developed to incorporate disc size and focal rim width into grading glaucomatous damage. The DDLS provides a quantitative method for diagnosing, staging, and monitoring glaucoma progression. While it has limitations for some disc types, the DDLS correlates well with visual field loss when used properly.

Cell Therapy Expansion and Challenges in Autoimmune DiseaseHealth Advances
There is increasing confidence that cell therapies will soon play a role in the treatment of autoimmune disorders, but the extent of this impact remains to be seen. Early readouts on autologous CAR-Ts in lupus are encouraging, but manufacturing and cost limitations are likely to restrict access to highly refractory patients. Allogeneic CAR-Ts have the potential to broaden access to earlier lines of treatment due to their inherent cost benefits, however they will need to demonstrate comparable or improved efficacy to established modalities.
In addition to infrastructure and capacity constraints, CAR-Ts face a very different risk-benefit dynamic in autoimmune compared to oncology, highlighting the need for tolerable therapies with low adverse event risk. CAR-NK and Treg-based therapies are also being developed in certain autoimmune disorders and may demonstrate favorable safety profiles. Several novel non-cell therapies such as bispecific antibodies, nanobodies, and RNAi drugs, may also offer future alternative competitive solutions with variable value propositions.
Widespread adoption of cell therapies will not only require strong efficacy and safety data, but also adapted pricing and access strategies. At oncology-based price points, CAR-Ts are unlikely to achieve broad market access in autoimmune disorders, with eligible patient populations that are potentially orders of magnitude greater than the number of currently addressable cancer patients. Developers have made strides towards reducing cell therapy COGS while improving manufacturing efficiency, but payors will inevitably restrict access until more sustainable pricing is achieved.
Despite these headwinds, industry leaders and investors remain confident that cell therapies are poised to address significant unmet need in patients suffering from autoimmune disorders. However, the extent of this impact on the treatment landscape remains to be seen, as the industry rapidly approaches an inflection point.

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.

6. Classic Indirect BIO Lenses
In 1956, aspheric ophthalmic lenses for subnormal vision were developed by Dr. David Volk. He found
that an aspheric surface corrected the aberrations present in more common spherical lenses.
Several developments occurred with the aspheric lens designs through the years, delivering far superior
imaging for BIO examinations. In 1982 all Volk lenses for indirect ophthalmoscopy were redesigned with
both surfaces aspheric, providing a substantial improvement in image quality.
The 20D and other Volk BIO lenses have been known as the industry standard for decades,
and are still widely used in every corner of the world today.

Digital Series Indirect BIO Lenses
In the Volk spirit of improvement, our 3rd generation, ‘Digital Series’ BIO lenses were developed from
the previous generation BIO lenses, in a similar fashion to the Digital Series slit lamp lenses. The goal: to
deliver enhanced resolution imaging with the indirect ophthalmoscope.
Working with a high grade glass, we looked at all aspects of their double aspheric designs with ad-
vanced computer modeling techniques. We realized improvements in all aspects of the BIO lens capa-
bilities, ultimately delivering the best image quality attainable for indirect ophthalmic exams.

10. Classic Slit Lamp Lenses
In 1956, aspheric ophthalmic lenses for subnormal vision were developed by Dr. David Volk. He found
that an aspheric surface corrected the aberrations present in more common spherical lenses.
Several developments occurred through the years, leading up to 1982 when all Volk lenses for indirect
ophthalmoscopy were redesigned with both surfaces aspheric, providing a substantial improvement in
image quality.
A series of indirect ophthalmoscopy lenses was developed, resulting in the choice of the 90 Diopter lens
as the most practical for indirect ophthalmoscopy with the slit lamp. The Volk 60D and 90D lenses were
commercialized providing a variety of characteristics; magnification, field of view and undilated pupil
examination.
The 60D and 90D lenses have been known as the industry standard for decades, having revolutionized
the slit lamp examination in the 1970s.

Super Series Lamp Lenses
Our drive to improve indirect imaging at the slit lamp led us to develop our 2nd generation slit lamp
lenses. Working with high grade glass types, we reviewed and improved the double aspheric designs
which were so successful in the classic 90D, 78D and 60D lenses, to bring the ‘Super Series’. A group
of 4 lenses was developed to deliver wide field, high magnification and specialty features such as
unsurpassed small pupil capabilities – the full diagnostic spectrum.

Digital Series Slit Lamp Lenses
The Digital Series are our 3rd generation, double aspheric, non-contact slit lamp lenses. Building on
the ‘Super Series’ lenses with high grade glass, we enhanced our double aspheric designs further
with advanced computer modeling. Also, gains in the quality of our A/R coating provided a notice-
able reduction in glare and reflections. We found that this helped improve slit lamp photographic
imaging. However, photography is not their sole purpose. The Digital Series lenses provide the finest
views for all examinations and imaging, enabling discernment of details previously unattainable at
the slit lamp.

Reinverting Operating Lens System® (ROLS®)
Primary Application – Provides high resolution reinverted images during vitreoretinal surgery
Overview – The ROLS unit is the most technically advanced panoramic viewing system to provide reinverted
images during vitreoretinal surgery.
Used in conjunction with Volk high magnification and wide field vitrectomy lenses, it delivers highest resolution
high magnification imaging of the macula and panoramic views up to the ora serrata.
• Precision prism surfaces for perfect image reproduction
• Easily installed on all standard surgical microscopes
• Advanced single element prism design guarantees image fusion and efficient light transmission
• Optional feature decreases working distance for more comfortable working position
• Easy to use, magnetic latching handles facilitate cleaning and sterilization
A ROLS+ reinverter (manual version only) delivers the added benefit of decreased working distance when
performing vitrectomy. Used when switching between a plano/concave lens to a wide field indirect lens, the
decreased working distance promotes a more comfortable working position.
21 Note : when used with an assistant scope, the ROLS+ reinverter may cause the assistant scope to be out of focus
on some microscopes
