Orbital Venous Malformation Excision after Transcaruncular Embolization with Onyx.

Orbital venous malformations are low-flow lesions resulting from vascular dysgenesis during development. Patients may present with vision loss, proptosis accentuated by Valsalva, and/or painful spontaneous thrombosis. The preferred treatment for symptomatic lesions is embolization combined with excision. A 34-year-old male presented to our institution from an outside emergency department with a diagnosis of presumed idiopathic orbital inflammation. For the prior month, he had been experiencing left orbital pressure, subjective eye bulging, and both diplopia and blurry vision when in peripheral gaze or when bending over. Despite initial improvement with steroids, his symptoms recurred with tapering. Visual acuity was reduced to 20/25, but pupils and motility remained normal. Biopsy demonstrated a vascular lesion characterized by fibroadipose tissue with histologically unremarkable blood vessels, and cerebral arteriography showed no high-flow components. A diagnosis of orbital venous malformation was made. He then underwent intraoperative angiography and Onyx embolization followed by excision via a transcaruncular approach. Two prior reports have described the use of Onyx in venolymphatic malformations. This report highlights a detailed approach to defining flow characteristics pre- and intraoperatively and expands upon our understanding of the use of Onyx for such cases.

Orbital Compartment Syndrome in Severe Burns: Predictive Factors, Timing, and Complications of Intervention.

PURPOSE: Severe burn patients require high-volume fluid resuscitation, which increases risk for orbital compartment syndrome (OCS). We aimed to understand surgeons' practice patterns and to examine risk factors for OCS, timing of lateral canthotomy and cantholysis (LCC), and complications of intervention. METHODS: A survey of American Society of Ophthalmic Plastic and Reconstructive Surgery and North American Society of Academic Orbital Surgeons' practice patterns in burn patients was undertaken. In addition, a retrospective analysis was conducted of 107 patients with burns greater than 20% total body surface area at 1 institution from January 1, 2009, to June 1, 2018. Patients with Stevens-Johnson Syndrome or Toxic Epidermal Necrolysis, frostbite, or no ophthalmologic consultation were excluded. Risk factors for OCS, timing of LCC, and complications of the intervention were examined. RESULTS: In the survey, 37 of 54 respondents had treated burn patients, of which 29 followed no protocol. Threshold intraocular pressure for intervention varied widely, and nearly all reported having seen complications from LCC in burn patients. For the retrospective analysis, 107 patients met criteria, of which 22 (20.6%) required LCC. Renal failure, inhalation injury, eyelid burns, higher total body surface area, elevated lactate, increased number of escharotomies, and greater total fluid required were significantly associated with the clinical decision that the patient was at risk for OCS requiring LCC. Fluid resuscitation in excess of the Ivy Index (250 ml/kg) increased odds of LCC 8.6 times. Average time of LCC was 15.8 hours after burn. LCC patients experienced higher rates of complications including eyelid retraction, exposure keratopathy, and corneal ulceration. CONCLUSIONS: Severe burn patients should be monitored closely by an ophthalmologist during the first 48 hours for signs of OCS. Further studies should aim to recommend protocols guiding evaluation and intervention.

Low Vision Referral Patterns in Intermediate Age-Related Macular Degeneration.

PURPOSE: Sparse data exist regarding low vision (LV) services referral patterns. We retrospectively examined our institution's intermediate age-related macular degeneration (iAMD) patients to determine factors influencing referral. METHODS: We compared visual acuity (VA) and Visual Function Questionnaire (VFQ-25) composite and subscale scores for referred and non-referred iAMD patients. VA was collected at time of referral or most recent visit, and VFQ-25 was taken upon enrollment into the registry. RESULTS: Thirty-six (15.5%) of the 232 iAMD patients were referred to LV. Referred patients were more likely to have older age, worse VA in both eyes, and lower VFQ-25 scores. Univariate analysis of VFQ-25 subscales demonstrated worse scores in general vision, near, distance, mental health, role limitations, dependency, and driving. Multivariable analysis revealed lower scores in general health, general vision, and driving. Forty-eight percent of non-referred patients had VA or VFQ-25 composite scores at least as poor as the median for referred patients. Two-thirds of patients who were not referred had no discernable obstacle to referral. CONCLUSIONS: Our institution refers patients with worse objective and functioning vision, but more patients may benefit from referral. Future studies should identify metrics to prompt referral and evaluate this approach.

An intraocular solitary fibrous tumor/hemangiopericytoma with extrascleral extension: Case report and review of literature.

Purpose: To report a case of intraocular solitary fibrous tumor/hemangiopericytoma (SFT/HPC) complicated by extrascleral extension and to review the current literature regarding intraocular SFT/HPC. Observations: A twenty-two year old male presented with decreased vision in his left eye and was found to have a subretinal mass with extrascleral extension. He underwent enucleation of his left eye and histopathology confirmed a diagnosis of SFT/HPC. Conclusions and importance: To our knowledge, this is the seventh case of intraocular SFT/HPC ever reported and the first to report extrascleral extension. At the time of publication, there was no evidence of metastases. Extensive clinical, ophthalmic and radiographic imaging, and histopathologic data are presented to contribute to the current understanding of intraocular SFT/HPC.

3D Printing in Eye Care.

Three-dimensional printing enables precise modeling of anatomical structures and has been employed in a broad range of applications across medicine. Its earliest use in eye care included orbital models for training and surgical planning, which have subsequently enabled the design of custom-fit prostheses in oculoplastic surgery. It has evolved to include the production of surgical instruments, diagnostic tools, spectacles, and devices for delivery of drug and radiation therapy. During the COVID-19 pandemic, increased demand for personal protective equipment and supply chain shortages inspired many institutions to 3D-print their own eye protection. Cataract surgery, the most common procedure performed worldwide, may someday make use of custom-printed intraocular lenses. Perhaps its most alluring potential resides in the possibility of printing tissues at a cellular level to address unmet needs in the world of corneal and retinal diseases. Early models toward this end have shown promise for engineering tissues which, while not quite ready for transplantation, can serve as a useful model for in vitro disease and therapeutic research. As more institutions incorporate in-house or outsourced 3D printing for research models and clinical care, ethical and regulatory concerns will become a greater consideration. This report highlights the uses of 3D printing in eye care by subspecialty and clinical modality, with an aim to provide a useful entry point for anyone seeking to engage with the technology in their area of interest.

Bilateral Placoid Choroiditis in an HIV-Positive Patient With Cryptococcus neoformans Meningitis and Disseminated Cryptococcal Disease.

Purpose: We report a presumptive case of bilateral placoid choroiditis secondary to disseminated Cryptococcus neoformans infection and review the literature on choroidal involvement of C neoformans. Methods: A case report is presented. Results: A 35-year-old HIV-positive man presented with disseminated cryptococcal infection. Cryptococcal meningitis was confirmed by lumbar puncture, and skin involvement was confirmed by microscopy of scrapings from a papular, umbilicated, ulcerated lesion. Ophthalmologic examination revealed intact visual acuity, clear vitreous, and multiple yellowish, placoid-appearing choroidal lesions in the posterior pole bilaterally. Conclusions: Multifocal choroiditis caused by C neoformans is an uncommon manifestation of disseminated infection, and placoid yellowish choroidal lesions are an unusual variant. These findings must be differentiated from choroidal tuberculosis and other infections. Multifocal choroiditis typically occurs in AIDS patients and may precede the presentation of meningitis. In such patients, choroidal lesions warrant investigation for systemic, life-threatening opportunistic infections.

Periorbital Subcutaneous Perfluoron Is Well Tolerated Following Intravitreal Surgery.

Purpose: Perfluorocarbon liquids (PFCLs) are well tolerated in intraocular surgery, but chronic exposure can cause inflammation. PFCL leakage into the orbit without significant sequelae has been reported, but PFCL leakage into the preseptal subcutaneous tissues has not been described. Methods: A case report is presented. Results: A 46-year-old man presented with hand motion vision from a ruptured globe and retained intraocular foreign body. Intraoperatively, the foreign body could not be removed, and PFCL extravasated from the posterior globe rupture. Postoperative imaging revealed hyperdense material in the orbit, lids, and superficial adnexal tissues. The patient tolerated the retained PFCL, and imaging 10 months later demonstrated interval resorption. The patient eventually developed ocular siderosis and underwent transconjunctival orbitotomy with foreign body extraction. Two years following the initial injury, his vision remained stable at 20/40 without further sequelae. Conclusions: PFCL is well tolerated in the extraocular space and may resorb with conservative management.

Augmented Posterior Hyaloid Adhesion Associated With Retinal Detachment After Macular Hole Repair.

BACKGROUND AND OBJECTIVE: There remains a low but intractable risk of rhegmatogenous retinal detachment (RRD) after surgical repair of macular holes (MHs). The purpose of this study is to identify potential causes for RRDs after MH surgery. PATIENTS AND METHODS: The authors retrospectively examined a single surgeon series of stage 3 MH repair surgeries during a 5-year period. Clinical data, including preoperative, intraoperative, and postoperative evaluations, were reviewed to determine potential causes of RRD. RESULTS: Of the 332 eyes that received MH surgery, 12 (3.6%) developed postoperative RRD. Seven RRD cases exhibited no evident precursor pathology; however, augmented posterior hyaloid adhesions (APHAs) were found intraoperatively and postoperatively. CONCLUSIONS: In MH surgery, APHA increases risk for RRD. During PPV, the vitreous typically separates to the peripheral vitreous base. Some eyes have APHAs near the equator that cannot be elevated, consistent with strong adhesion. The authors believe the high postoperative RRD rate is due to continued hyaloid elevation after surgery. [Ophthalmic Surg Lasers Imaging Retina. 2019;50:635-638.].
