Use of a Novel Three-dimensional Head-mounted Digital Visualization Platform in Corneal Endothelial Transplantation.

INTRODUCTION: To report the first endothelial keratoplasty procedures performed using a 3D digital head-mounted ophthalmic exoscope. METHODS: Three patients underwent Descemet stripping automated endothelial keratoplasty (DSAEK) using a 3D digital ophthalmic exoscope (Beyeonics One, Beyeonics Vision, Haifa, Israel) at the Tel Aviv Sourasky Medical Center, Tel Aviv, Israel. RESULTS: All procedures were uneventful, leading to resolution of corneal edema and vision improvement. Surgeons reported excellent visualization and minimal lag, almost negligible, with the benefits of improved ergonomics and the use of head gestures to control zoom, focus, brightness, and panning. There were no postoperative complications. CONCLUSION: The new 3D digital ophthalmic exoscope system can be successfully used in DSAEK surgery with potential advantages in ergonomics, picture quality, and image control. Further studies can compare this system with either standard operating microscopes or 3D heads-up display systems.

An Elderly Man with Atypical Multiple Evanescent White Dot Syndrome.

A rare occurrence of an atypical case of multiple evanescent white dot syndrome (MEWDS) in a 75-year-old man without viral prodrome or white dots on fundus that presented with acute, severe left eye visual loss, which returned to baseline without treatment in several weeks. Multimodal imaging, including fluorescein angiography (FA), fundus autofluorescence (FAF), indocyanine green angiography (ICG), and optical coherence tomography (OCT) demonstrated classical presentation of MEWDS with wreath-like lesions and inflammatory foci in the retinal pigment epithelium that correlated among modalities. Possible underlying systemic disorders were ruled out through extended work up. To the best of our knowledge, this is the first report to show atypical MEWDS in an elderly man with classic changes on FA, FAF, ICG, and OCT.

Outcomes following Laser Retinopexy for Retinal Tears: A Comparative Study between Trainees and Specialists.

OBJECTIVE: To compare the outcomes of laser retinopexy for the treatment of retinal tears between residents and specialists, and to identify tear characteristics associated with the risk of progression to retinal detachment (RD). METHODS: A retrospective review of 307 eyes treated by laser retinopexy, categorized by the performing physician, either a resident (217 cases) or a specialist (90 cases). Recorded parameters included the number, size, and location of the retinal tears, the presence of bridging vessels, vitreous hemorrhage (VH), or subretinal fluid (SRF), the need for additional laser, progression to RD, and surgery. RESULTS: Additional laser was performed in 42.3% of cases in the resident group and 35.5% in the specialist group (p = 0.26). Progression to RD occurred in 6.9% of cases in the resident group and 5.5% in the specialist group (p = 0.66). The presence of VH and SRF were associated with an increased risk of progression to RD (p < 0.0001 and 0.003, respectively). A higher proportion of cases with SRF were treated by specialists (p = 0.006). CONCLUSIONS: Laser retinopexy is safely and effectively performed by residents, with no worse outcomes than procedures performed by specialists. A high rate of additional laser may be needed to achieve RD prophylaxis, and higher-risk cases can be identified at presentation and then referred to specialists.
