Autoimmune retinopathy with associated anti-retinal antibodies as a potential immune-related adverse event associated with immunotherapy in patients with advanced cutaneous melanoma: case series and systematic review.

OBJECTIVE: To demonstrate the spectrum of autoimmune retinopathy (AIR) associated with immunotherapy for advanced cutaneous melanoma. METHODS AND ANALYSIS: Retrospective chart review on patients with advanced cutaneous melanoma who developed AIR after initiating immunotherapy. Complete ophthalmic examination and relevant ancillary testing were performed on each patient. The presence of AIR-associated anti-retinal antibodies was confirmed by western blot and/or immunohistochemical staining. Ophthalmic and systemic outcomes after treatment for AIR were followed over time. A systematic review of AIR associated with immunotherapy for cutaneous or non-ocular mucosal melanoma was carried out in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. RESULTS: Case 1 developed photopsia and nyctalopia with electroretinographic findings characteristic for melanoma-associated retinopathy 1 week after initiating ipilimumab/nivolumab immunotherapy. Case 2 experienced new severe bilateral visual field loss associated with anti-retinal and anti-optic nerve antibodies while on maintenance nivolumab immunotherapy. Case 3 developed decreased visual acuity due to acute exudative polymorphous vitelliform maculopathy within 2 weeks of initiating ipilimumab/nivolumab immunotherapy. All patients had concurrent extraocular immune-related adverse events in addition to the presence of anti-retinal antibodies on serological testing. 14 published cases of AIR associated with immunotherapy for cutaneous or non-ocular mucosal melanoma were identified and reviewed. CONCLUSIONS: Immune checkpoint inhibition can trigger the development of AIR with varied clinical manifestations in patients with advanced cutaneous melanoma. This study highlights the need for close monitoring in cutaneous melanoma patients receiving immunotherapy who develop new visual symptoms with or without funduscopic changes, as well as the potential role for screening of patients prior to initiating immunotherapy.

Spinal Ewing Sarcoma Metastatic to Bilateral Orbits.

A 39-year-old woman with primary spinal Ewing sarcoma and known lung metastases presented with painless bilateral decreased visual acuity over a 1-month period. Examination revealed bilateral disc edema. MRI of the brain/orbits showed metastatic lesions to the dura and bilateral orbits. Venous sinus thrombosis extending to the jugular vein was also noted. To the authors' knowledge, this is the first case of bilateral orbital metastasis and papilledema secondary to Ewing sarcoma and related hypercoagulability.

Incorporating patient-specific CT-based ophthalmic anatomy in modeling iodine-125 eye plaque brachytherapy dose distributions.

PURPOSE: To quantify the dosimetric impact of incorporating patient-specific CT-based models rather than the conventional stylized-standard model for eye plaque brachytherapy planning. METHODS AND MATERIALS: Plaque Simulator was used to plan 16 patients using both CT-based patient-specific eye model and stylized-standard (SS) eye models. Plaque position was initially based on the SS model and compared against their patient-specific model without changing the plaque loading pattern and seed strength. Dosimetric parameters were compared for tumor and healthy ocular structures. RESULTS: Patient-specific ocular parameters ranged from 0.40 to 1.38 of SS model values. If plaques were placed based on SS model eyelet positions, target volume receiving prescription dose (V100%) is overpredicted by 5.9% on average (max: 27%), and D95% is overpredicted by 17.2 Gy on average (max: 58.1 Gy). If the plaques were recentered, 13 of 16 patients had changes in V100% of less than 2%, whereas half of the patients still had optic disc dose difference greater than 5 Gy (max: 36.2 Gy). The largest differences were observed with a target-to-optic disk distance less than 6 mm. No substantial dose differences were observed for the tumor apex, fovea, lens, and opposing retina. CONCLUSIONS: Patient-specific modeling is recommended for clinical planning, especially with target-to-optic disk distances less than 6 mm, due to significant differences compared with SS model.

Blepharoplasty markers: comparison of ink drying time and ink spread.

Marking of the eyelid is a crucial presurgical step in blepharoplasty. A number of markers are available for this purpose with variable ink characteristics. In this study, we measured the ink drying time and spread width of 13 markers used for preoperative marking for blepharoplasty. Based on the results, we propose markers that may be best suited for use in this procedure.

Effect of endoscopic cyclophotocoagulation on refractive outcomes when combined with cataract surgery.

OBJECTIVE: To determine the difference between predicted and actual refractive outcomes after combined endoscopic cyclophotocoagulation and cataract surgery (phaco-ECP) in patients with open-angle glaucoma (OAG). DESIGN: Retrospective case-control study of patients with OAG who underwent phaco-ECP compared with cataract surgery alone. PARTICIPANTS: Eighty-three patients with OAG, aged 55 to 91 years, who underwent a combined phaco-ECP procedure and 58 biometry- and age-matched control patients with OAG who underwent cataract surgery alone. METHODS: Patient records were retrospectively reviewed at the Department of Ophthalmology and Visual Sciences, Washington University School of Medicine in St. Louis (St. Louis, Mo.). The primary outcome was the difference in predicted and actual refractive outcomes in patients undergoing either phaco-ECP or standard cataract surgery. RESULTS: Compared with phaco alone, the difference in predicted versus actual postoperative results was more myopic in the phaco-ECP group (0.029, -0.110, and -0.095 vs -0.169, -0.325, and -0.312 [p < 0.05] for Sanders, Retzlaff, Kraff/Theoretical, Hoffer Q, and Holladay, respectively). Moreover, the F test for variability showed significantly more variability in refractive outcomes in the phaco-ECP group compared with standard cataract surgery. CONCLUSIONS: Patients undergoing phaco-ECP may have postoperative refractive errors that may vary from that predicted preoperatively more so than in cataract surgery alone. Surgeons may consider analyzing their results to determine whether any adjustment should be made to lens power selection when performing phaco-ECP.
