Multiple evanescent white dot syndrome-like reaction associated with ipilimumab and nivolumab immune checkpoint inhibitor therapy for metastasis of choroidal melanoma.

PURPOSE: To present a rare case of multiple evanescent white dot syndrome (MEWDS)-like presentation associated with immune checkpoint inhibitor therapy for metastatic choroidal melanoma. OBSERVATIONS: A 67-year-old non-myopic Caucasian female presented with bilateral worsening vision, flashes, and floaters after receiving two doses of ipilimumab and nivolumab for metastatic class 2 peripheral choroidal melanoma. Fundus imaging of the right eye revealed hypopigmented, extra-foveal scattered chorioretinal lesions with foveal granularity. Fluorescein angiogram and autofluorescence of the right eye demonstrated corresponding hyperfluorescent and hyperautofluorescent lesions in a wreath-like configuration. Optical coherence tomography of the right eye revealed subretinal fluid. Due to concurrent systemic side effects, checkpoint inhibitor therapy was paused and the patient was started on oral prednisone. At her one month follow up visit, her vision in her right eye returned to baseline and subretinal fluid resolved. CONCLUSIONS: This is the first reported case of a MEWDS-like chorioretinopathy after two cycles of ipilimumab/nivolumab therapy for metastatic choroidal melanoma. As immune checkpoint inhibitor therapy is still an evolving field, more research is needed to characterize ocular side effect profiles of these agents.

Scleral Buckling for Primary Retinal Detachment: Outcomes of Scleral Tunnels versus Scleral Sutures.

PURPOSE: There are primarily two techniques for affixing the scleral buckle (SB) to the sclera in the repair of rhegmatogenous retinal detachment (RRD): scleral tunnels or scleral sutures. METHODS: This retrospective study examined all patients with primary RRD who were treated with primary SB or SB combined with vitrectomy from January 1, 2015 through December 31, 2015 across six sites. Two cohorts were examined: SB affixed using scleral sutures versus scleral tunnels. Pre- and postoperative variables were evaluated including visual acuity, anatomic success, and postoperative strabismus. RESULTS: The mean preoperative logMAR VA for the belt loop cohort was 1.05 ± 1.06 (Snellen 20/224) and for the scleral suture cohort was 1.03 ± 1.04 (Snellen 20/214, p = 0.846). The respective mean postoperative logMAR VAs were 0.45 ± 0.55 (Snellen 20/56) and 0.46 ± 0.59 (Snellen 20/58, p = 0.574). The single surgery success rate for the tunnel cohort was 87.3% versus 88.6% for the suture cohort (p = 0.601). Three patients (1.0%) in the scleral tunnel cohort developed postoperative strabismus, but only one patient (0.1%) in the suture cohort (p = 0.04, multivariate p = 0.76). All cases of strabismus occurred in eyes that underwent SB combined with PPV (p = 0.02). There were no differences in vision, anatomic success, or strabismus between scleral tunnels versus scleral sutures in eyes that underwent primary SB. CONCLUSION: Scleral tunnels and scleral sutures had similar postoperative outcomes. Combined PPV/SB in eyes with scleral tunnels might be a risk for strabismus post retinal detachment surgery.

Impact of contact versus non-contact wide-angle viewing systems on outcomes of primary retinal detachment repair (PRO study report number 5).

BACKGROUND/AIMS: Vitrectomy to repair retinal detachment is often performed with either non-contact wide-angle viewing systems or wide-angle contact viewing systems. The purpose of this study is to assess whether the viewing system used is associated with any differences in surgical outcomes of vitrectomy for primary non-complex retinal detachment repair. METHODS: This is a multicenter, interventional, retrospective, comparative study. Eyes that underwent non-complex primary retinal detachment repair by either pars plana vitrectomy (PPV) alone or in combination with scleral buckle/PPV in 2015 were evaluated. The viewing system at the time of the retinal detachment repair was identified and preoperative patient characteristics, intraoperative findings and postoperative outcomes were recorded. RESULTS: A total of 2256 eyes were included in our analysis. Of those, 1893 surgeries used a non-contact viewing system, while 363 used a contact lens system. There was no statistically significant difference in single surgery anatomic success at 3 months (p=0.72), or final anatomic success (p=0.40). Average postoperative visual acuity for the contact-based cases was logMAR 0.345 (20/44 Snellen equivalent) compared with 0.475 (20/60 Snellen equivalent) for non-contact (p=0.001). After controlling for numerous confounding variables in multivariable analysis, viewing system choice was no longer statistically significant (p=0.097). CONCLUSION: There was no statistically significant difference in anatomic success achieved for primary retinal detachment repair when comparing non-contact viewing systems to contact lens systems. Postoperative visual acuity was better in the contact-based group but this was not statistically significant when confounding factors were controlled for.

Surgical Outcomes of Primary RRD With and Without Concurrent Full-Thickness Macular Hole (PRO Study Report No. 7).

BACKGROUND AND OBJECTIVE: Non-causal macular holes (MHs) can occur concurrently with rhegmatogenous retinal detachments (RRDs). The visual outcomes and surgical approach for these eyes are variable. PATIENTS AND METHODS: This was a multi-institutional, retrospective review of all primary retinal detachment surgeries from January 1, 2015, through December 31, 2015. Pre-, intra-, and postoperative metrics were recorded. RESULTS: There were 2,242 eyes that had pars plana vitrectomy for primary RRD, 43 (1.9%) of which had a MH at the time of surgery. The mean postoperative logMAR visual acuity (VA) for the MH cohort was 0.87 ± 0.64 (20/148) and for eyes without a MH was 0.47 ± 0.63 (20/59; P < .0001). The single-surgery re-attachment rate for the MH cohort and no MH cohort was 86.1% and 84.9%, respectively (P = 1.0000). CONCLUSIONS: Patients with noncausal MHs and RRD had significantly worse VA than patients without a MH. Preoperative counseling is imperative in patients with both RRD and MH.

Complications and adverse events of plaque brachytherapy for ocular melanoma.

Plaque brachytherapy is a well-accepted modality to manage selected cases of ocular melanoma. Although this modality provides validated oncologic and quality of life benefits, severe complications and adverse events can occur. This article reviews complications and adverse events of plaque brachytherapy, including scleral necrosis, strabismus, cataract, glaucoma, and retinopathies as well as management of these conditions. For practicing oncologists and ophthalmologists, these complications are important to understand, identify, and treat. Additionally, an understanding of common complications of brachytherapy should influence the decision of pursuing it as a treatment option.

Therapeutic potential of curcumin in major retinal pathologies.

PURPOSE: The retina is continually exposed to free radicals from its rich blood supply, numerous mitochondria, and photons of light which strike its surface. Most pathological processes that take place in the retina, such as inflammation, cell apoptosis, or angiogenesis, can hence involve free radicals directly or indirectly.  Since inflammatory and oxidative stress pathways underlie retinal pathology, compounds that address these factors are therefore natural choices for treatment. This review article summarizes and provides commentary on curcumin's therapeutic potential use in ophthalmology with principal focus on retinal dosorders. METHODS: Curcumin (diferuloylmethane) is a compound of the Indian spice turmeric (Curcuma longa) that has been found to be efficacious in preventing and treating a number of inflammatory diseases and neoplastic processes. Curcumin exerts anti-inflammatory, anti-tumor, antioxidant, and VEGF inhibition properties through modulation of numerous biochemical mediators. This makes curcumin particularly effective in retinal disorders. RESULTS: Curcumin has found a role in slowing, and in some cases even reversing, age-related macular degeneration, diabetic retinopathy, retinitis pigmentosa, proliferative vitreoretinopathy, and retinal cancers. CONCLUSIONS: However, studies on curcumin's efficacy have been limited mostly to animal studies. Moreover, the biomedical potential of curcumin is not easy to use, given its low solubility and oral bioavailability-more attention therefore has been given to nanoparticles and liposomes.

Role of Curcumin in Common Musculoskeletal Disorders: a Review of Current Laboratory, Translational, and Clinical Data.

The Indian spice turmeric, in which the active and dominant biomolecule is curcumin, has been demonstrated to have significant medicinal properties, including anti-inflammatory and anti-neoplastic effects. This promise is potentially very applicable to musculoskeletal disorders, which are common causes of physician visits worldwide. Research at the laboratory, translational and clinical levels that supports the use of curcumin for various musculoskeletal disorders, such as osteoarthritis, osteoporosis, musculocartilaginous disorders, and sarcoma is here in comprehensively summarized. Though more phase I-III trials are clearly needed, thus far the existing data show that curcumin can indeed potentially be useful in treatment of the hundreds of millions worldwide who are afflicted by these musculoskeletal disorders.
