Ophthalmic Immune-Related Adverse Events and Association with Survival: Results from a Real-World Database.

PURPOSE: Assessing immune-related ocular toxicities from immune checkpoint inhibitors (ICIs) is crucial, though rare. This study, utilizing real-world data, examines the occurrence of ophthalmic immune-related adverse events (irAEs) after ICI treatment and their impact on overall survival. DESIGN: A retrospective cohort study METHODS: Data were obtained from TriNetX, an aggregated electronic health records database. Patients who developed ophthalmic irAEs within 1 year after the first instance of ICI therapy were included. Participants with defined ocular toxicities 6 months before ICI treatment were excluded. Subjects were paired with controls using propensity scores derived from demographics and cancer type. A Cox proportional hazard model was used to determine hazard ratios. A Kaplan-Meier survival function was evaluated with the log-rank test based on the development of ophthalmic irAEs in a 12-month landmark analysis. RESULTS: A cohort of 41,020 patients comprising 57.4% males with a mean age of 65.2±11.9 years was included. The five most prevalent ophthalmic irAEs in this cohort were dry eye syndrome (2%), conjunctivitis (0.87%), blepharitis (0.51%), anterior uveitis (0.39%), and keratitis (0.38%). Dry eye syndrome was the most common irAE among all ICI classes. Subjects taking CTLA-4 inhibitor plus PD-1 inhibitor and CTLA-4 inhibitors had higher rates of anterior uveitis (1.39% and 1.29%, respectively) than PD-1 inhibitors (0.27%) and PD-L1 inhibitors (0.14%) within 1 year after taking ICI. After a 12-month landmark analysis, there was a significant decreased chance of survival for the following categories: any ophthalmic irAE (HR, 1.37; 95% CI, 1.20-1.56; P < 0.0001), neuro-ophthalmic irAE (HR, 1.53; 95% CI, 1.09-2.14; P = 0.0124), and cornea and ocular surface irAE (HR, 1.34; 95% CI, 1.15-1.56; P < 0.0001). CONCLUSIONS: Ophthalmic irAEs involving the anterior segment are more frequent than the posterior segment, regardless of ICI class. Ophthalmic irAEs may also portend decreased survival. This insight could help guide clinicians aggressively manage irAEs and allow patients to continue ICI therapy despite having ocular issues.

Importance of Baseline Fluorescein Angiography for Patients Presenting to Tertiary Uveitis Clinic.

PURPOSE: To ascertain whether the use of ultra-wide-field fluorescein angiography (UWFFA) at baseline visit alters the assessment of disease activity and localization, as well as the management of patients presenting to a tertiary uveitis clinic. DESIGN: Retrospective comparison of diagnostic approaches. METHODS: Baseline visits of 158 patients who presented to the Uveitis Clinic at the Byers Eye Institute at Stanford between 2017 and 2022 were evaluated by 3 uveitis-trained ophthalmologists (I.K., A.B., and H.G.). Each eye had undergone clinical examination along with ultra-wide-field fundus photography (UWFFP) (Optos Plc), spectral-domain optical coherence tomography (SD-OCT, Spectralis Heidelberg, Heidelberg Engineering) and UWFFA (Optos Plc) at the baseline visit. Investigators were asked to successively determine disease activity, localization of disease (anterior, posterior or both), and management decisions based on clinical examination and UWFFP and SD-OCT (Set 1) and Set 1 plus UWFFA (Set 2). The primary outcome was the percentage of eyes whose management changed based on the availability of UWFFA compared with Set 1. RESULTS: The mean age of the patients was 46.9 ± 22.4 years (range, 7-96), and 91 (57.6%) were female. With Set 1 alone, 138 eyes (55.2%) were found to have active disease; localization was anterior in 58 eyes (42.0%), posterior in 53 eyes (38.4%), and anterior + posterior in 27 eyes (19.6%). With Set 2, 169 eyes of 107 patients had active anterior, posterior, or panuveitis. In comparison with Set 1, assessment with Set 2 identified additional 31 eyes (18.3%) with active disease (P = .006) and an additional 31 eyes (18.3%) having disease in both anterior + posterior segments (P < .001). Regarding the primary outcome, management was changed in 68 eyes (27.4%) in Set 2 compared with Set 1. CONCLUSIONS: Baseline UWFFA may alter assessment of disease activity, localization, and management decisions compared with clinical examination with only UWFFP and SD-OCT for eyes with uveitis. Thus, UWFFA may be considered as an essential tool in the evaluation of patients with uveitis at the baseline visit.

Structural and Functional Changes in Non-Paraneoplastic Autoimmune Retinopathy.

BACKGROUND: To describe longitudinal changes in patients with non-paraneoplastic autoimmune retinopathy (npAIR) by utilizing different diagnostic modalities/tests. METHODS: The index study is a retrospective longitudinal review of sixteen eyes of eight patients from a tertiary care eye hospital diagnosed with npAIR. Multiple diagnostic modalities such as wide-angle fundus photography (WAFP), WA fundus autofluorescence (WAFAF), spectral-domain optical coherence tomography (SD-OCT), Goldmann visual field (GVF) perimetry, microperimetry (MP), electrophysiologic testing, and adaptive optics scanning laser ophthalmoscopy (AOSLO) were reviewed and analyzed. RESULTS: At the baseline visits, anomalies were detected by multimodal diagnostic tests on all patients. Subjects were followed up for a median duration of 11.5 [3.0-18.7] months. Structural changes at the baseline were detected in 14 of 16 (87.5%) eyes on WAFP and WAFAF and 13 of 16 (81.2%) eyes on SD-OCT. Eight of the ten (80%) eyes that underwent AOSLO imaging depicted structural changes. Functional changes were detected in 14 of 16 (87.5%) eyes on GVF, 15 of 16 (93.7%) eyes on MP, and 11 of 16 (68.7%) eyes on full-field electroretinogram (ff-ERG). Multifocal electroretinogram (mf-ERG) and visual evoked potential (VEP) tests were performed in 14 eyes, of which 12 (85.7%) and 14 (100%) of the eyes demonstrated functional abnormalities, respectively, at baseline. Compared to all the other structural diagnostic tools, AOSLO had a better ability to demonstrate deterioration in retinal microstructures occurring at follow-ups. Functional deterioration at follow-up was detected on GVF in 8 of 10 (80%) eyes, mf-ERG in 4 of 8 (50%) eyes, and MP in 7 of 16 (43.7%) eyes. The ff-ERG and VEP were stable in the majority of cases at follow-up. CONCLUSIONS: The utilization of multimodal imaging/tests in the diagnosing and monitoring of npAIR patients can aid in identifying anomalous changes over time. Analysis of both the anatomical and functional aspects by these devices can be supportive of detecting the changes early in such patients. AOSLO shows promise as it enables the capture of high-resolution images demonstrating quantifiable changes to retinal microstructure.
