Vitreomacular disorders: a review of the classification, pathogenesis and treatment paradigms including new surgical techniques

This review explores how optical coherence tomography has guided our assessment of vitreomacular disorders. Vitreomacular disorders (VMD), such as macular holes and epiretinal membranes are common and potentially sight threatening. The introduction and widespread use of optical coherence tomography (OCT) imaging technology has transformed our ability to visualise the vitreoretinal interface. This review discusses the pathogenesis and updated classification scheme for VMD in the OCT era. Imaging biomarkers and the treatment algorithm, including the role of novel therapeutics, for managing patients with VMD are presented.

Cost-effectiveness analysis of ocriplasmin versus watchful waiting for treatment of symptomatic vitreomacular adhesion in the US

Aim: Evaluate the cost-effectiveness of ocriplasmin in symptomatic vitreomacular adhesion (VMA) with or without full-thickness macular hole ≤400 μm versus standard of care. Methods: A state-transition model simulated a cohort through disease health states; assignment of utilities to health states reflected the distribution of visual acuity. Efficacy of ocriplasmin was derived from logistic regression models using Ocriplasmin for Treatment for Symptomatic Vitreomacular Adhesion Including Macular Hole trial data. Model inputs were extracted from Phase III trials and published literature. The analysis was conducted from a US Medicare perspective. Results: Lifetime incremental cost-effectiveness ratio was US$4887 per quality-adjusted life year gained in the total population, US$4255 and US$10,167 in VMA subgroups without and with full-thickness macular hole, respectively. Conclusion: Ocriplasmin was cost effective compared with standard of care in symptomatic VMA.

Morphological Reconstitution and Persistent Changes After Intravitreal Ocriplasmin for Vitreomacular Traction and Macular Hole

Purpose: To assess the long-term anatomical and functional findings in patients with symptomatic vitreomacular traction (VMT), with or without full thickness macular hole (FTMH), after eye treatment with intravitreal ocriplasmin injection (IOI). Methods: This longitudinal case series includes 51 eyes from 51 symptomatic patients with VMT (<800 μm) who received a single IOI (Jetrea^® 0.125 mg); 21 cases with an FTMH (<400 μm) were included. Best-corrected visual acuity (BCVA) and optical coherence tomography findings were recorded before IOI, and 1 day to 24 months thereafter. Data are presented as mean ± standard deviation. Results: Mean adhesion size before injection was 345 ± 146 μm. In 34 eyes (67%), complete release of VMT was observed; whereas VMT persisted in 17 eyes (33%). The latter included 15 of the 21 eyes (71%) with FTMH, 15 of which underwent pars plana vitrectomy and inner limiting membrane peeling. BCVA improved from (logarithm of the minimal angle of resolution [logMAR]) 0.41 ± 0.03 before injection to 0.32 ± 0.03 after 1 month and 0.23 ± 0.05 after 6 months and remained stable thereafter (0.24 ± 0.06 after 24 months of follow-up). Forty-five percent of the eyes presented submacular deposits soon after IOI that were not functionally relevant; 61% completely resolved by 12 months. Except floaters that disappeared within 48 h, no other adverse events were reported during follow-up. Conclusions: Treatment with ocriplasmin in a real-life setting showed an overall efficacy of 67% in patients with symptomatic VMT, with better results evident in the absence of an FTMH (70% vs. 62% VMT release) and a visual gain for over 2 years.
