EFFICACY AND SAFETY OF TREATMENT OPTIONS FOR VITREOMACULAR TRACTION: A Case Series and Meta-Analysis.

PURPOSE: To evaluate treatment options for vitreomacular traction (VMT). METHODS: A retrospective, consecutive case series and a literature search with Boolean search logic. A random-effects meta-analysis was conducted to combine the rates of VMT resolution per treatment. Patients from studies analyzed were placed into cohorts based on the treatment received. CASE SERIES: Zero of 10 control, 3 of 7 intravitreal ocriplasmin (IVO, P = 0.10), 7 of 8 intravitreal expansile gas (pneumatic vitreolysis, PV, P < 0.01), and 10 of 10 pars plana vitrectomy (P < 0.01)-treated eyes experienced VMT release (VMTr) at Day 28. No patients developed retinal tears or detachment. One PV-treated (12.5%) eye developed a macular hole. Meta-analysis: Twenty-three of 131 prospective or retrospective and consecutive articles were included. Sixty-three eyes were treated with PV, 726 eyes were treated with intravitreal ocriplasmin, and 253 eyes were characterized as the control group (saline injection). The weighted rate of VMT resolution for the control group was 0.09 (95% confidence interval [CI]: 0.06-0.13), PV was 0.84 (95% CI: 0.76-0.92), and intravitreal ocriplasmin was 0.26 (95% CI: 0.23-0.29). CONCLUSION: Our analysis found that PV releases VMT in most patients and suggest that PV may be as effective or superior to nonsurgical options for VMTr at Day 28 with a similar risk profile.

Choroidal thickness and vessel pattern in myopic eyes with dome-shaped macula.

AIM: To analyse the choroidal thickness (CT) and vessel pattern of myopic patients with dome-shaped macula (DSM) and their association with the DSM axis and serous retinal detachment (SRD). METHODS: Retrospective study. The CT and vessel pattern were assessed on optical coherence tomography (OCT), OCT-angiography and ultra-wide-field photography. RESULTS: 27 eyes of 18 subjects (mean age: 65 years) were included. Compared with the 11 eyes (41%) with horizontal DSM, the 16 eyes (59%) with vertical DSM had a shorter axial length (25.8±2 mm vs 28.3±2.5 mm; p=0.01), a higher mean macular bulge height (624.4±207 µm vs 255.4±160.3 µm; p=0.0001) and a thicker CT (183.1±91.1 µm vs 72±38.3 µm; p<0.001). Large choroidal vessels crossed the macular area in 75% of eyes with vertical DSM vs 27% of eyes with horizontal DSM (p=0.02), whereas a watershed zone framing the macula was more often seen in horizontal DSM (72% vs 25%, p=0.02). Thirteen eyes (48%) had an SRD that was not associated with the DSM axis, the mean bulge height, the CT or the vessel pattern. CONCLUSION: The presence of an SRD did not correlate with the DSM axis, the CT or the vessel pattern. However, the rate of large choroidal vessels crossing the macula was higher in vertical DSM than in horizontal DSM.
