Injectable Fluocinolone Implant for the Management of Cystoid Macular Edema in Coats' Disease.

A six-year-old boy with history of Coats' disease and cystoid macular edema (CME) was treated with a combination of peripheral retinal laser, anti-vascular endothelial grown factor injections, and short-acting injectable steroids to control his disease process. Given the excellent response to shorter acting steroids and the need for general anesthesia for each procedure, the patient underwent placement of the injectable fluocinolone acetonide implant 0.18 mg (YUTIQ) with control of his CME at 30 months of follow-up. The authors conclude that a long-acting steroid implant may be beneficial in select patients with Coats' disease. [Ophthalmic Surg Lasers Imaging Retina 2024;55:XX-XX.].

Essential Tremors: A Literature Review of Current Therapeutics.

Essential tremors (ETs) commonly manifest as involuntary shaking of the hands that disrupt daily activities. These tremors involve the central motor network of the cerebellum, thalamus, and cortical networks, leading to different clinical phenotypes. The goal of this review was to establish evidence-based recommendations for effective care and simplify decisions for those dealing with ET. For this narrative literature review, we conducted a thorough search using core keywords such as "essential tremor" and "therapy." From the 27 selected articles, relevant data were presented regarding pathophysiology, medications, and other treatment options, with necessary supplemental data such as side effects and use cases. This paper examines treatments for ET, including commonly prescribed medications such as propranolol and primidone; invasive treatments such as deep brain stimulation, focused ultrasound thalamotomy, transcranial magnetic stimulation, and some surgical methods; and non-invasive methods such as the neuromodulation technique of transcutaneous afferent patterned stimulation. Overall, this study presents a synthesized understanding of the currently available modalities for managing ETs. It is intended to guide care providers in choosing the best possible method to contain symptoms.

Severe Spontaneous Tilt of Scleral-Fixated Intraocular Lenses.

PURPOSE: To report and evaluate a multicenter series of 18 cases of severe, spontaneous IOL tilt involving the flanged intrascleral haptic fixation technique (FISHF). DESIGN: Clinical study with historical controls. METHODS: We report a cross-sectional study of 46 FISHF cases using the CT Lucia 602 IOL at a single academic center over a period of 24 weeks to determine the incidence of severe rotisserie-style rotational tilt. These rates were then compared with the same time-frame the prior year to help determine if this is a new phenomenon. Additional cases of severe tilt were solicited from another 4 academic centers. RESULTS: Among 46 FISHF cases at a single center, 5 developed severe tilt. No clear pattern in surgical technique, ocular history, or ocular anatomy was evident in these cases compared with controls, although the involved IOLs clustered within a narrow diopter range, indicative of a batch effect. In the same 24-week interval the year before, 33 FISHF cases were performed, none of which exhibited severe rotational tilt. In our multicenter dataset, 18 cases of tilt were identified. Surgeons included fellow and early-career physicians as well as surgeons with multiple years of experience with the Yamane technique. A variety of surgical approaches for FISHF were represented. In at least 8 of the cases, haptic rotation and/or dehiscence at the optic-haptic junction were documented. CONCLUSIONS: The identification of haptic rotation and dehiscence intraoperatively in several cases may reflect a new stability issue involving the optic-haptic junction.

Orbital compartment syndrome following primary scleral buckle surgery.

PURPOSE: To illustrate a patient with orbital compartment syndrome following scleral buckle placement that was successfully treated with canthotomy and cantholysis. METHODS: Observational case report. RESULTS: A 26-year-old male underwent a primary scleral buckle repair for a chronic rhegmatogenous retinal detachment. On post-operative day four, the patient presented to the emergency room with pain and increased intraocular pressure (IOP). Initial treatment with conservative IOP lowering agents was unsuccessful. The patient was diagnosed with delayed orbital compartment syndrome and was successfully managed with lateral canthotomy and inferior cantholysis in addition to aggressive steroid and antibiotic medical management. CONCLUSION: Following scleral buckle placement with sub-tenon's anesthesia block, there may be a delayed presentation of orbital compartment syndrome. Recognition and management of this rare complication is important for preventing irreversible blindness.

INJECTABLE FLUOCINOLONE IMPLANT FOR THE MANAGEMENT OF CHRONIC POSTSURGICAL CYSTOID MACULAR EDEMA IN VITRECTOMIZED EYES.

PURPOSE: Long-acting injectable steroids are changing the treatment paradigm for patients with chronic intraocular inflammation and cystoid macular edema (CME). We report the use of the fluocinolone implant 0.18 mg in patients with chronic postsurgical CME after pars plana vitrectomy. METHODS: This is a retrospective case series of 24 vitrectomized eyes which received fluocinolone implant for the management postsurgical CME. Clinical outcomes and requirement for rescue therapy were studied. RESULTS: Median length of follow-up was 19.3 months (range 8.3-23.2 months). There was an improvement in median central subfield thickness from 412 µ m (range 167-806 µ m) to 311 µ m (range 157-686 µ m) after fluocinolone implant ( P < 0.001). The injection burden decreased significantly after study treatment ( P < 0.001); however, there was no significant change in visual acuity ( P = 0.334). Eighteen eyes had control of CME that did not require additional intravitreal therapy. Four eyes had initially controlled but recurrent CME requiring intravitreal steroid therapy at median of 7.8 months (range 7.6-15.4 months). One eye never attained sufficient inflammatory control despite rescue therapy. CONCLUSION: Fluocinolone implant can be an effective treatment in vitrectomized patients with chronic postsurgical CME and can help decrease the overall injection burden.

Uveitis and Posterior Ophthalmic Manifestations Following the SARS-CoV-2 (COVID-19) Vaccine.

PURPOSE: To present four cases of posterior ophthalmic manifestations associated with a temporal relationship to SARS-CoV-2 vaccination. METHODS: Retrospective case series with a review of clinical findings. RESULTS: Four patients presented with various posterior ophthalmic findings including uveitis, maculopathy, and optic neuropathy. Each of their clinical courses varied in terms of ophthalmic imaging and exam findings. CONCLUSION: The coronavirus disease 2019 (COVID-19) pandemic has ushered in a new wave of challenges to healthcare, epidemiological endeavors, and widespread vaccination efforts. Novel vaccines have been developed for the SARS-CoV-2 virus, including both mRNA and viral vector-based platforms. The ocular manifestations and side effects related to the SARS-CoV-2 vaccine is not well established or understood. There may be an association between vaccination and posterior ophthalmic manifestations.

TWENTY-FIVE AND TWENTY-SEVEN-GAUGE SUTURELESS INTRASCLERAL FIXATION OF INTRAOCULAR LENSES: Clinical Outcomes and Comparative Effectiveness of Haptic Flanging in a Large Single-Surgeon Series of 488 Eyes.

PURPOSE: To describe the clinical outcomes and surgical technique in transconjunctival sutureless intrascleral fixation of intraocular lenses, including the effectiveness of haptic flanging and peripheral iridotomy. METHOD: Retrospective series of patients who underwent sutureless intrascleral fixation of three-piece intraocular lenses by a single surgeon. RESULTS: A total of 488 eyes were included in this study. Mean follow-up was 444 days. Mean preoperative best-corrected visual acuity was 20/355, and mean postoperative best-corrected visual acuity was 20/39 (P < 0.001). Intraocular lens dislocation occurred during the postoperative period in 67 (13.7%), with the majority (65.7%) occurring within 3 months after surgery. Dislocation occurred in 13 of 196 (6.6%) flanged haptics versus 54 of 292 (18.5%) unflanged haptics (P < 0.001). Reverse pupillary block occurred in 7 of 231 eyes (3.0%) without intraoperative peripheral iridotomy but only in 1 of 257 eyes (0.4%) with iridotomy (P = 0.0297). Other complications included haptic exposure (1.2%), retinal detachment (1.0%), and endophthalmitis (0.4%). CONCLUSION: This is the largest reported series of sutureless intrascleral fixation of intraocular lenses using trocar cannulas. This technique is an effective surgical option with low complication rates. The authors recommend that haptic flanging and peripheral iridotomy be performed in all cases.

A Rare Case of Isolated Intramedullary Spinal Cord Cysticercosis.

Neurocysticercosis is a parasitic disease often involving the central nervous system by Taenia solium and is commonly seen in developing countries. The majority of these cases have either isolated brain involvement or combined involvement of the brain and spinal cord. Isolated involvement of the spinal cord is very rare. We report the case of a 20-year-old Indian man who was hospitalized for progressive weakness in all extremities. Magnetic resonance imaging showed a well-defined, round, thick-walled, peripherally enhancing lesion in the intramedullary region, a provisional diagnosis of isolated cysticercosis of the intramedullary region of the spinal cord was made. The patient improved upon needle aspiration of the cystic lesion after surgery, which on post-surgical histological examination confirmed the diagnosis by showing the presence of cysticerci.
