Background: Uveitis is defined as a collection of syndromes involving intraocular inflammation which can lead to pain, tissue damage, and vision loss. Ophthalmic surgery in uveitis patients can be challenging due to inflammation-induced fibrosis and scarring. Trabeculectomy and implantation of glaucoma drainage devices (aqueous shunts) have been used in surgical management of uveitic glaucoma, however there is a paucity of literature examining the comparative results of these entities in this unique setting.

Observations: We report a case of a 71-year-old Caucasian male with metastatic melanoma who presented with bilateral cystoid macular edema after being on treatment with a programmed T cell death ligand 1 inhibitor, MPDL3280, for 1 year. Multimodal imaging techniques, including color fundus photographs, autofluorescence, spectral domain optical coherence tomography (OCT), fluorescein angiography (Spectralis, Heidelberg, Germany), and spectral-domain OCT angiography (Zeiss; California, USA) were performed to evaluate the etiology of his CME and to monitor his response to treatment.
Purpose: To present the multimodal retinal imaging findings, including optical coherence tomography (OCT) angiography, of an atypical case of acute macular neuroretinopathy (AMN).
Methods: The multimodal retinal imaging findings, including structural OCT and OCT angiography, of an atypical case of AMN are presented.
Results: A 23-year old woman, with a history of an unrelenting sinusitis treated with prednisone therapy and decongestants, presented with an acute scotoma of the right eye.
Purpose Of Review: To review recent literature pertaining to sickle cell retinopathy (SCR) and, in particular, sickle cell maculopathy.
Recent Findings: Several recent studies suggest that macular perfusion abnormalities seen in patients with sickle cell disease of various genotypes may affect both the superficial and deep capillary plexi, with a predilection for the deep capillary plexus. Further, these changes may be associated with areas of macular thinning, as well as with peripheral retinal ischemia, even in individuals without visual symptoms, contrary to what has previously been described in both diabetic retinopathy and retinal vein occlusion.
Purpose: To evaluate visual and anatomical outcomes of diabetic tractional retinal detachment repaired with pars plana vitrectomy.
Methods: Operative records were used to retrospectively identify all patients with tractional retinal detachments secondary to proliferative diabetic retinopathy surgically repaired with pars plana vitrectomy between November 1, 2009, and January 1, 2015 at the LAC + USC (Los Angeles County + University of Southern California) Medical Center.
Results: A total of 403 eyes with diabetic tractional retinal detachment in 359 patients were included.
Evaluate parylene scaffold feasibility in cartilage lesion treatment, introducing a novel paradigm combining a reparative and superficial reconstructive procedure. Fifteen rabbits were used. All animals had both knees operated and the same osteochondral lesion model was created bilaterally.

Purpose: While there are many known etiologies of choroidal neovascularization (CNV), tuberculosis is not a well-known causative agent. In this case series, we highlight CNV occurring secondary to tuberculous chorioretinitis, its presentation, and its management.
Observations: We retrospectively reviewed the charts and imaging of four patients who presented with presumed tuberculous chorioretinitis and CNV.

A 25-year-old Hispanic female presented with 5 months of dry eyes and 2 months of bilateral photophobia and decreased vision. On examination, she had bilateral anterior uveitis and mild disc edema of the left eye. A complete infectious and inflammatory work-up was positive for elevated antinuclear antibodies and p-ANCA, leading to a diagnosis of microscopic polyangiitis.

Methods: Descriptive case report. A 25-year-old woman with retinitis pigmentosa presented with decreased visual acuity, interested in a second opinion.
Purpose: To describe a case of small retinal vessel vasculopathy postvaccination.
Methods: We report the case of a 41-year-old white man who presented with a "second blind spot," describing a nasal scotoma in the right eye that started 4 days after vaccinations against Neisseria meningitidis and the yellow fever virus, and after a 2-month period of high stress and decreased sleep. Clinical examination, Humphrey visual field testing, and multimodal imaging with fundus photographs, autofluorescence, fluorescein angiography, and spectral domain optical coherence tomography and angiography were performed.

Purpose: We present a patient with systemic lupus erythematosus with significant vaso-occlusive retinal findings mimicking antiphospholipid antibody syndrome, who developed Kikuchi-Fujimoto disease.
Observations: Our patient was initially diagnosed with systemic lupus erythematosus with antiphospholipid antibody syndrome given consistent serologic markers and profound retinal vascular ischemia. However, on subsequent follow up, she presented with fever and lymphadenopathy and underwent lymph node biopsy, which declared histologic findings of Kikuchi-Fujimoto disease.

A general method for chemical surface functionalization of parylene C [PC, (para-CH2-C6H3Cl-CH2-)n] films is reported. Friedel-Crafts acylation is used to activate the surface of the PC film, and the resulting carbonyl groups are then used to form a range of different organic functional groups to the surface of the parylene film, including alcohol, imine, thiol, phthalimide, amine, and maleimide. The presence of these functional groups on the parylene surface was confirmed by Fourier transform infrared spectroscopy.

In order to achieve such an implant, new technology is needed, since the state-of-the-art implantable neural stimulator has at most 22 contacts with neural tissue. Considerable progress has been made towards that goal with the development of image processing, microelectronics, and polymer based electrodes and interconnects.
