The introduction of magnetic resonance imaging (MRI) in 1978 represented a remarkable and substantial shift in the landscape of diagnostic medicine. Nuclear resonance phenomena allow for the utilization of differential proton properties within living tissue. Computed tomography is surpassed by this method, owing to its capacity for high and variable contrast and the non-use of ionizing radiation. Serving as the diagnostic instrument of choice, it is a crucial component of evaluating the location and characteristics of various ocular and orbital pathologies, including those of a vascular, inflammatory, or neoplastic nature.
Multi-parametric ophthalmological evaluation hinges on MRI's inherent and extrinsic characteristics. MRI dynamic color mapping provides a non-invasive and quantitative measure of the motion of soft tissues. A thorough understanding of MRI's fundamental principles and techniques is instrumental in both diagnostic accuracy and the optimal design of surgical procedures.
The anatomical, clinical, and radiological elements of MRI will be presented in this video, using overlap to improve comprehension of this innovative technology's significance.
An in-depth understanding of MRI analysis empowers ophthalmologists to make independent judgments about differential diagnoses, allowing them to define the precise extent and infiltration, creating effective surgical plans, and ultimately reducing the risk of unfavorable outcomes.

Rhino-orbito-cerebral mucormycosis, the predominant form of mucormycosis, often results from severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection as a secondary fungal infection. Among the uncommon sequelae of ROCM, osteomyelitis stands out, with frontal osteomyelitis being the least frequent. Four patients with COVID-19, treated for rhino-orbital-cerebral mucormycosis with surgical and medical approaches, demonstrated the onset of frontal bone osteomyelitis. This initial case series, detailing this post-COVID-19 mucormycosis complication, is a crucial reminder of its life-threatening nature and potential for extreme facial disfigurement, demanding immediate attention. A miraculous recovery: all four patients are alive, with the affected globes saved and vision retained in one. Early diagnosis is essential to prevent facial disfigurement and intracranial extension.
Filamentous fungi from the Mucoraceae family, specifically causing rhino-orbital mucormycosis, were once considered a rare ailment, primarily affecting immunocompromised individuals and those with ketoacidosis, until the advent of the COVID-19 pandemic. This presentation examines six patients diagnosed with rhino-orbital-cerebral mucormycosis, each presenting with central retinal artery occlusion. Each of the six cases exhibited a comparable past medical history of a recent COVID-19 infection, characterized by sinusitis, proptosis, complete ophthalmoplegia, and the additional finding of central retinal artery occlusion upon their presentation. The MRI demonstrated the invasive nature of pan-sinusitis, affecting the orbits and the cerebral tissues. Urgent debridement was performed, and histopathological testing showed broad, filamentous aseptate fungi, characteristic of Mucormycosis. All patients, despite receiving intravenous Amphotericin B and local debridement, experienced no improvement and succumbed to their illness within a week of their presentation. The findings of our study highlight a poor prognosis in cases of mucormycosis linked to post-COVID-19 infection, including central retinal artery occlusion.

For a successful extraocular muscle surgery, an uneventful and smooth scleral suture pass is indispensable. Normal intraocular tension usually leads to a predictable and safe surgical operation. However, a noticeable degree of hypotony complicates matters considerably. For the purpose of reducing the complication rate in these scenarios, we have implemented the simple technique of pinch and stretch. The surgical methodology for this technique, in cases of severe ocular hypotony, includes the following steps: A routine forniceal/limbal peritomy procedure is executed, then the muscle is sutured and dislodged. Three tissue fixation forceps are employed for the stabilization of the scleral surface. Tooth biomarker The surgeon, using the first pair of forceps, rotates the eye globe towards themselves, commencing from the muscle's remnant, while the assistant, with the two remaining forceps, grasps and extends the episcleral tissue outward and upward, precisely below the targeted markings. A firm, flat scleral surface is produced as a consequence. Without encountering any problems, the operation concluded with sutures being passed over the stiff sclera.

Mature, hypermature, and traumatic cataracts are alarmingly common in developing countries, hindering access to the surgical resources and expertise required to address the resultant aphakia and leaving sufferers needlessly blind. The restricted availability of secondary intraocular lenses (IOLs) stems from the dependence on posterior segment surgeons, the high cost of surgical equipment, and the necessary selection of appropriate lenses for aphakia management. Given the acknowledged efficacy of the flanging technique and the readily available polymethyl methacrylate (PMMA) lenses, each possessing dialing holes in their optical components, a hammock can be assembled by passing a 7-0 polypropylene suture through the dialing holes using a straight needle. Through a 4-flanged scleral fixation method using the dialing hole of an intraocular lens, even anterior segment surgeons can now scleral-fixate a PMMA lens, thereby eliminating the requirement for specialized equipment or the utilization of eyelet-equipped scleral-fixated lenses. This method was successfully applied in 103 cases, without any instances of the IOL shifting from its intended position.

Sight-threatening corneal melt is a known complication of Boston type 1 keratoprosthesis (KPro). Hypotony, choroidal hemorrhage, and possible spontaneous KPro extrusion, resulting from severe corneal melt, can negatively impact visual prognosis. Selleck Fulvestrant In cases of mild corneal melt, the surgical procedure of lamellar keratoplasty becomes a vital option, especially when a fresh KPro is not readily accessible. We showcase the use of intra-operative optical coherence tomography (iOCT), a new surgical method, in the management of cornea graft melt after the implantation of a Boston type 1 KPro. Taxaceae: Site of biosynthesis The postoperative six-month examination revealed sustained visual acuity and intraocular pressure, with the KPro implant remaining stable and showing no signs of corneal melting, epithelial ingrowth, or infection. For corneal lamellar dissection and suturing beneath the KPro's anterior plate, iOCT could prove to be a real-time, non-invasive, and accurate treatment option, aiding surgical decisions and potentially reducing post-operative problems.

This article assesses the one-year impact of the novel Glauco-Claw intra-ocular implant on refractory chronic angle-closure glaucoma (ACG). The implant, Glauco-Claw, a novice polymethylmethacrylate device, is distinguished by a central ring and five claws arranged around it in a circular array. The anterior chamber housed the placement, with the peripheral iris secured within the claws, thereby initiating goniosynechialysis and averting the recurrence of goniosynechiae. Five sets of eyes from five separate patients received implants, and these individuals were followed up for a full twelve months. All patients demonstrated sustained achievement and maintenance of intra-ocular pressure targets until their last follow-up visit. Two patients avoided the need for any anti-glaucoma medication. No complications of any kind were observed in any of the patients. Glauco-Claw, a novel approach, could offer another tool in the armamentarium for managing chronic angle-closure glaucoma that doesn't respond to other methods.

Myopia's rapid increase in prevalence, a global issue prominently affecting India, has become a major public health concern over the years. A concomitant rise in myopia's prevalence is expected to amplify its clinical and socioeconomic repercussions. Consequently, the emphasis has been redirected towards the prevention of myopia's onset and advancement. Currently, myopia management lacks any formalized, widely adopted guidelines. Within the Indian context, this document seeks to generate a national-level expert consensus regarding the handling of childhood myopia. The expert panel, comprised of 63 pediatric ophthalmologists, convened for a hybrid meeting. The experts were given a pre-meeting list of topics slated for discussion, and were expected to contribute their views during the meeting. Following a presentation of the items, the panel of experts offered their insights into each, carefully considered different dimensions of childhood myopia, and arrived at a unified conclusion regarding the prevailing patterns of practice in India. Should opposing viewpoints or a lack of clear consensus emerge, we proceeded to further discussions and assessment of existing literature, thereby aiding in the attainment of a consensus. A comprehensive report is prepared based on the recommendations, detailing myopia definition, refractive techniques, diagnostic elements, initiating anti-myopia treatment, outlining types and timing of interventions, establishing a follow-up schedule, and the options for adapted or combined treatment approaches.
