Mucopolysaccharidosis type II B complicated by optic disc swelling, pigmentary retinopathy and macular edema.

PURPOSE: To report clinical and imaging features of optic nerve and retinal involvement in a patient with mucopolysaccharidosis (MPS) type II B. METHODS: A 27-year-old man, diagnosed with MPS type II B and undergoing enzymatic substitution therapy for the past 19 years, was referred to the retina service. An ophthalmological evaluation, which included multimodal imaging, was conducted to investigate potential retinal and optic disc involvement. RESULTS: The eye examination revealed a pigmentary retinopathy with a predominant loss of the outer retinal loss, primarily in the parafoveal and perifoveal regions. Notably, multimodal imaging identified macular edema without any signs of leakage, implying an association between macular edema and retinal neurodegeneration. Additionally, both eyes exhibited an optic disc with blurred margins. CONCLUSION: We herein describe the multimodal imaging findings of retinal and optic disc involvement in a patient with MPS type II B. This report describes for the first-time the presence of macular edema without leakage alongside photoreceptor damage and optic disc swelling.

Relationship of Topographic Distribution of Macular Atrophy Secondary to Neovascular AMD and Reading Performance.

Purpose: The purpose of this study was to provide a topographical assessment of macular atrophy in successfully treated neovascular age-related macular degeneration (AMD) eyes to investigate determinants of monocular reading performance. Methods: A total of 60 participants (60 eyes) with previously treated neovascular AMD and absence of optical coherence tomography (OCT) signs of exudation were enrolled. Reading performance was assessed monocularly using Radner charts. The following variables were obtained: (i) the reading acuity was defined as the logarithm of the reading acuity determination (LogRAD), at the smallest sentence, a patient is able to read in less than 30 seconds; (ii) the maximum reading speed was defined as the fastest time achieved and is calculated in words per minute (wpm). OCT images were reviewed for the presence of macular atrophy within the central, 4 inner and 4 outer Early Treatment Diabetic Retinopathy Study (ETDRS) grid subfields. Contributory factors affecting reading performance were examined using univariable and multivariable linear mixed model considering reading acuity and reading speed as dependent variables. Results: Median (interquartile range [IQR]) values were 0.53 (IQR = 0.17) LogRAD for reading acuity, and 144 (60) wpm for maximum reading speed. Thirty-five out of 60 (58.3%) eyes were characterized by the presence of macular atrophy. In multiple regression analysis, reading acuity was significantly associated with presence of macular atrophy in the foveal central circle (P = 0.024). Conversely, the maximum reading speed was associated with presence of macular atrophy in the inner-right ETDRS subfield (P = 0.005). Conclusions: We showed a significant relationship between presence and location of macular atrophy and reading performance in neovascular AMD.

INTERSESSION REPEATABILITY OF READING PERFORMANCE MEASURES IN PATIENTS WITH NEOVASCULAR AGE-RELATED MACULAR DEGENERATION.

PURPOSE: To assess the intersession repeatability of reading performance measures in patients with previously treated neovascular age-related macular degeneration and good best-corrected visual acuity (≥20/40 Snellen). METHODS: Ninety-one patients (91 eyes) with a diagnosis of previously treated neovascular age-related macular degeneration and good best-corrected visual acuity (≥20/40 Snellen) were prospectively enrolled. Reading performance metrics were assessed using Radner charts, and these measurements were repeated after 7 days to obtain the intersession repeatability. To test repeatability, we calculated the intraclass correlation coefficient, the 95% coefficient of repeatability, and the coefficient of variation for each reading parameter: 1) reading acuity (RA-LogRAD); 2) maximal reading speed-words per minute; 3) RA score (RA score-LogRAD); and 4) critical print size-LogRAD. RESULTS: Mean ± standard deviation best-corrected visual acuity was 0.13 ± 0.01 logMAR [range: 0.00-0.30 logMAR]. The intraclass correlation coefficient values indicated a good reliability for all the analyzed metrics (0.901 for RA; 0.859 for max reading speed; 0.906 for RA score; and 0.868 for critical print size). The coefficient of repeatability was 0.2 LogRAD for RA, 63.2 words per minute for max reading speed, 0.2 LogRAD for RA score, and 0.2 LogRAD for critical print size. Coefficient of variation was 5.5% for RA, 8.9% for max reading speed, 5.8% for RA score, and 6.9% for critical print size. CONCLUSION: Reading performance metrics are characterized by good values of intersession repeatability in patients with neovascular age-related macular degeneration with good best-corrected visual acuity. Our findings may grant the employment of such measures in trials assessing the visual outcome in these patients.

Quality of Life during Treatment with Lenvatinib for Thyroid Cancer: The Patients' Perspective beyond the Medical Evaluation.

BACKGROUND: Lenvatinib (LEN) has shown great efficacy but important toxicity in patients with advanced radioactive iodine-refractory (RAI-R) thyroid cancer (TC); a focused evaluation of its impact on patients' quality of life (QoL) is still lacking. Our prospective study investigated the impact of this drug on QoL in a group of RAI-R TC patients treated at our centre. METHODS: All patients filled in two questionnaires before and during treatment: (1) the Patient-Reported Outcomes version of the Common Terminology Criteria for Adverse Events adapted questionnaire, assessing prevalence, severity, and/or interference on daily activities of the most frequent symptomatic adverse events (AEs) reported in previous clinical trials during therapy with LEN, and (2) the European Quality of Life 5 Dimensions 3 Levels (EQ-5D-3L) questionnaire, providing the EQ-5D index and the EQ visual analogue scale (EQ-VAS). Data from baseline questionnaires were compared with those obtained 3, 6, and 12 months after the start of treatment. RESULTS: In our population (n = 20), an overall increased perception of symptomatic AEs emerged during treatment (statistically significant for abdominal pain, asthenia/fatigue, decreased appetite, and xerostomia). The median EQ-5D index and EQ-VAS scores after 3 months of treatment were lower than at baseline, almost returning to initial values after 12 months. CONCLUSION: RAI-R TC patients reported a general increase in prevalence and interference on daily activities of symptomatic AEs during therapy with LEN. Self-perceived QoL initially decreased during therapy. However, our data suggest that QoL could be restored after 12 months; this trend might partly reflect the impact of therapy optimisation.
