Faricimab in Previously Treated Eyes With Neovascular Age-Related Macular Degeneration: An Assessment of Durability and Treatment Outcomes.

BACKGROUND AND OBJECTIVE: This study evaluated the efficacy and durability of faricimab in patients with neovascular age-related macular degeneration (nAMD) who were previously treated with anti-vascular endothelial growth factor (anti-VEGF) agents. PATIENTS AND METHODS: This retrospective case series was conducted at a single tertiary center in the United States. It focused on nAMD patients who transitioned to faricimab after initial anti-VEGF therapy, with a follow-up period of at least 9 months. "Complete dryness" was defined as the absence of intra- and/or subretinal fluid on optical coherence tomography. Durability was gauged by the extension of treatment intervals relative to the injection frequency of the previous agent. RESULTS: Sixty-two eyes from 62 patients were included. Treatment interval ranged from 5 to 10 weeks; 10 (16%) patients were able to be extended by 2 or more weeks compared to their previous regimen. Median (interquartile range [IQR]) central field thickness was 310 µm (254, 376) on initiating faricimab and declined by the ninth month (P values at 3, 6, and 9 months were 0.01, 0.02, and 0.07, respectively). Median (IQR) visual acuity at initiation of faricimab was 0.4 (0.20, 0.50) and did not change by the ninth month. Complete anatomical dryness was present in 10 (16%) eyes before switching; 90% remained dry at 9 months. Of 52 (84%) incompletely dry eyes before switching, 15% achieved complete dryness by 9 months on faricimab. CONCLUSIONS: Faricimab modestly improved the treatment intervals for a small proportion of previously treated patients on anti-VEGF therapy. [Ophthalmic Surg Lasers Imaging Retina 2024;55:XX-XX.].

Dynamic Infrared Imaging of Vitreous Floaters.

Background and Objective: To evaluate the use of dynamic infrared (IR) imaging as a tool for the objective evaluation of symptomatic vitreous floaters and to correlate it with the patient symptomatology. Study Design/Materials and Methods: Retrospective study that examined 66 eyes of 44 patients with symptomatic and asymptomatic vitreous opacities. Patients were imaged using the Heidelberg Spectralis dynamic infrared (IR) image in video mode to record the vitreous movements and shadow artifacts within 30 degrees of the center of the macula. Patients were also asked how symptomatic their vitreous floaters were from absent to severe. After reviewing IR videos and OCT, a grading system was created to evaluate the floaters and a masked reader was asked to evaluate the videos and OCT based on the grading system created. Results: A total of 66 eyes were identified and examined with the IR videos, 50 were symptomatic, and 16 were asymptomatic. After masked review and analysis of the IR videos, there were 4 characteristics that correlated with the patient's symptoms: size, location, movement, and density of obscuration of the OCT B Scan by the vitreous opacity. A table with grading of these characteristics was created to analyze how symptomatic patients were. A masked grader was asked to grade the videos and OCT using the grading system created. A positive correlation was found between the masked grader and the symptoms of patients. (0.70039; p < 0.00001). Conclusion: Dynamic IR video capture of vitreous opacities is a new imaging technique that can qualitatively assess vitreous opacities in a way that correlates to a patient's symptoms. This imaging modality can provide a qualitative assessment of the patient's severity of symptoms based on the location, density, and movement of the visualized vitreous opacities in the imaged video.

Acute serous and hemorrhagic choroidal effusion associated with topical dorzolamide therapy.

Purpose: To report a case of acute onset unilateral hemorrhagic and serous choroidal effusion associated with dorzolamide administration and antiplatelet use that recurred in a patient who experienced a dorzolamide-induced choroidal effusion ten years prior to presentation. Observations: A 78-year-old male with a history of POAG in both eyes presented with sudden onset decreased vision and flashes of light in the left eye two days after escalating from timolol maleate 0.5% twice daily in both eyes to fixed combination dorzolamide-timolol 22.3-6.8 mg/mL twice daily in both eyes. Systemic medication included daily aspirin 81 mg for primary prevention of cardiovascular disease. Dilated fundus examination and B-scan ultrasound of the left eye revealed a hemorrhagic choroidal effusion in the nasal retinal periphery and low lying serous choroidal effusion in the temporal periphery. Complete resolution of the choroidal detachment was achieved in four days following prompt cessation of dorzolamide, and treatment with topical prednisolone acetate 1% four times daily and atropine 1% two times daily. Conclusions and importance: Topical dorzolamide may induce an idiosyncratic reaction leading to serous and hemorrhagic choroidal effusion, which can be exacerbated by antiplatelet use. Prompt recognition and management of drug-induced choroidal effusion can lead to improved visual outcomes and prevent long-term sequelae.

Clinical Outcome of Cystoid Macular Edema in Silicone Oil-Filled Eyes.

Purpose: To investigate the clinical outcome of cystoid macular edema (CME) in eyes undergoing silicone oil (SO) tamponade with subsequent SO removal (SOR). Methods: A retrospective case series of adult patients with CME treated with SO tamponade and SOR was conducted between January 2015 and January 2021. Exclusion criteria included eyes with a prior SO tamponade, those that did not undergo SOR, or those with infectious/inflammatory diagnoses. The primary outcomes were the incidence and resolution rates of CME in eyes with SO tamponade that had undergone SOR. The secondary outcomes included changes in best-corrected visual acuity (BCVA) and central field thickness (CFT). Results: Nineteen eyes of 19 patients (58% men) aged 52 years (interquartile range [IQR], 45-66 years) met the study inclusion criteria. The median (IQR) follow-up duration post SOR was 22 (8-35) months. The mean CFT decline for the CME-resolved cases was 13.1 µm/mo (P = .257). CME resolved in only 10 eyes (53%), 7 (67%) of which occurred after SOR. The median (IQR) BCVA was 20/400 (20/200 to 20/1262) at CME diagnosis and 20/796 (20/252 to hand motions) after SOR, with 0.184 worsening in logMAR BCVA (P = .340). Medical treatment was not associated with CME resolution compared with observation (50% vs 89%, respectively; P = .069). Eyes with proliferative vitreoretinopathy (PVR) had a higher rate of persistent CME compared with eyes with other diagnoses (78% vs 10%, respectively; P = .005). Conclusions: Nearly half had nonresolution of CME after SO was removed. The VA at the last follow-up was unaffected by CME resolution. Preoperative PVR may be a risk factor for unresolved CME.

Brain atrophy and lesion load are related to CSF lipid-specific IgM oligoclonal bands in clinically isolated syndromes.

INTRODUCTION: The objective of this work is to study the relationship between the presence of lipid-specific oligoclonal IgM bands (LS-OCMB) in CSF, with both T2 lesion volume (T2LV) accumulation and brain atrophy (percentage change of brain volume-PCBV-and brain parenchyma fraction-BPF) in patients with clinically isolated syndromes (CIS) suggestive of demyelination. METHODS: Twenty-four CIS patients were included in this prospective study. IgG oligoclonal bands (OCGB) and LS-OCMB were determined in paired serum and CSF samples within 3 months since clinical onset. Brain MRI studies were scheduled at baseline, 3 months, first and second years after CIS onset. Differences in T2LV, PCBV and BPF between CIS patients according to the type of OCB were studied. RESULTS: Nine patients had no OCB; 15 had only OCGB, and seven had OCGB + LS-OCMB present in the CSF. LS-OCMB were associated with greater T2LV in all scheduled MRI studies. At the end of follow-up (year 2), it was threefold higher in patients with these antibodies than in those without LS-OCMB (3.95 cm(3) vs. 1.36 cm(3), p = 0.001). At that point, brain atrophy was also higher in patients with LS-OCMB (BPF, 0.73 in LS-OCMB+ patients vs. 0.76 in negative ones, p = 0.03). The rate in brain atrophy was higher in the first group of patients as well. Considering only patients with OCGB, the presence of LS-OCMB was also related to greater T2LV, T2LV increase and a trend towards higher atrophy rate. CONCLUSION: The presence of LS-OCMB in the first event suggestive of demyelination is related to an early increase in lesion load and brain atrophy. These data are in line with prospective studies showing the clinical prognostic value of LS-OCMB.

Pulsed steroids followed by glatiramer acetate to prevent inflammatory activity after cessation of natalizumab therapy: a prospective, 6-month observational study.

In this study, the tolerability and safety of treatment with pulsed steroids and glatiramer acetate and the occurrence of clinical and radiological activity after natalizumab (NTZ) cessation in multiple sclerosis (MS) patients were assessed. MS patients with NTZ were discontinued after 2 years of treatment, or if adverse events or disease progressed during NTZ. They were offered as alternative treatment 1 g methylprednisolone per month during 3 months followed by daily 20 mcg glatiramer acetate and were prospectively studied. Adverse events, occurrence of immune reconstitution inflammatory syndrome, clinical exacerbations, and gadolinium-enhancing lesions in MRI performed at 3 and 6 months after NTZ cessation were recorded. EDSS change during follow-up was also recorded. A total of 18 MS patients entered the study and were followed up for a mean of 10 months (range 6-18 months). There were no significant adverse events. At month 3, no patient had clinical or radiological disease activity. At month 6, 16.6% of patients had had a relapse and 55.5% of patients showed gadolinium-enhancing lesions in the MRI. After 6 months, 33.3% of patients had a further relapse. There was no IRIS, severe relapses, or significant difference between EDSS at NTZ discontinuation and after follow-up. The alternative treatment with monthly prednisolone followed by GA prevents the development of IRIS, but not the return to previous inflammatory activity, which occurs between 5 and 6 months after NTZ withdrawal.
