Visual Outcomes after Proton Therapy for Recurrent Uveal Melanoma.

OBJECTIVE: Proton beam reirradiation remains an effective and globe-preserving alternative to enucleation in the treatment of local recurrence in uveal melanoma. The study aimed to assess visual outcomes and prognostic factors in visual acuity following proton beam salvage therapy. DESIGN: Retrospective study SUBJECTS: A retrospective study evaluated patients with recurrent uveal melanoma treated with proton beam irradiation (PBI) from 1984 through 2019 at a single academic tertiary center. METHODS: Patient and tumor characteristics were collected from the medical record, as well as best visual acuity (BVA) and ocular outcomes following treatment of recurrent uveal melanoma with PBI. MAIN OUTCOME MEASURES: The primary outcome of the study was the visual acuity of patients following proton beam irradiation for recurrent uveal melanoma. Additional outcome measures included enucleation rate of patients following salvage PBI and analysis of tumor and patient characteristics in the prognostication of visual acuity. RESULTS: The study comprised 67 patients who received PBI for recurrent uveal melanoma. The median age at recurrence was 67.6 years (range 31.6-91.0 years) and median follow-up from the time of recurrence to last examination was 4.4 years (range 0.23-17.1 years). The median final BVA was hand motion (range 20/20-no light perception) and 6 (9.1%) patients maintained a Snellen VA 20/40 or better. The 5-year probability of visual acuity retention of 20/200 or better was 19%. In a multivariable Cox model, VA at tumor recurrence of less than 20/40 was found to be significantly associated with a VA of 20/200 or worse following retreatment with PBI. Twelve (18%) patients underwent enucleation following retreatment with PBI. CONCLUSIONS: PBI allows for ocular preservation and functional vision in the treatment of recurrent uveal melanoma in select patients.

Demographics, Presenting Features, and Outcomes of Adult Patients with Ocular Trauma.

Introduction: Ocular trauma is a common cause of permanent vision loss in adults. The combination of an accurate clinical examination and imaging offers the best prognostic indicators for patients and helps to navigate treatment modalities. This is a retrospective chart review of examination and imaging findings for ocular trauma and how they correlate with treatment course and visual acuity (VA) outcomes. Methods: Adult patients with ocular trauma presenting to a single institution between January 2013 and December 2020 were evaluated. Initial examination and imaging findings were compared for associations with each other and with VA outcomes. Results: 136 ocular traumas on 134 patients were included. The median presenting logMAR VA was 2.7 (interquartile range (IQR) 1.2-3.7) with 62% open globe injuries. The most commonly reported finding on initial CT scan was globe deformity (30%), on B-scan was choroidal detachment (20%), and on ultrasound biomicroscopy was intraocular foreign body, ciliochoroidal effusions, or angle recession (21% each). Worse vision was observed for patients positive for retinal detachment on initial B-scan compared to those negative for this finding at 6-month (median logMAR 2.7 vs. 0.5; P < 0.0001) and at final post-injury evaluation (median logMAR 3.7 vs. 0.4; P < 0.0001). Similarly, worse VA was observed for patients with choroidal detachment on initial B-scan compared to those without this finding at 6-month (median logMAR 1.4 vs. 0.5; P = 0.002) and at final post-injury evaluation (median logMAR 2.0 vs. 0.4; P < 0.0001). If positive conjunctiva/sclera examination findings were identified, 66% had positive findings on B-scan, whereas if the conjunctiva/sclera examination findings were absent, 41% had positive findings on B-scan (P = 0.005). If anterior chamber (AC) examination findings were positive, 59% had positive findings on B-scan, whereas if the AC examination findings were absent, 37% had positive findings on B-scan (P = 0.03). Discussion. The predictive value of examination findings in this study may offer insight as to long-term visual prognosis. Positive B-scan or CT findings should increase suspicion for open globe injuries.

Long-Term Visual Outcomes in Patients With Idiopathic Epiretinal Membrane Surgery.

BACKGROUND AND OBJECTIVE: Our aim was to assess long-term outcomes following surgical repair of idiopathic epiretinal membrane (ERM) with pars plana vitrectomy (PPV) and membrane peel (MP). PATIENTS AND METHODS: A retrospective study evaluated patients with idiopathic ERM who underwent surgical repair at a single academic tertiary center with five to nine years of postoperative follow-up, assessing preoperative characteristics, surgical techniques, best visual acuity (BVA), and optical coherence tomography biomarkers at various time points. RESULTS: The study involved 67 patients (72 eyes) with an average postoperative follow-up of 82.8 ± 18.8 months. Patients with cone outer segment tips integrity at initial presentation and 1-year follow-up and patients with external limiting membrane and ellipsoid zone integrity at 1-year follow-up were noted to have significantly better long-term visual acuity than those without. More than 85% of patients achieved a BVA > 70 seven years after surgical repair. CONCLUSIONS: Vitreoretinal surgery for idiopathic ERM resulted in improved anatomical recovery and sustained visual acuity gain over long-term follow-up.
