A Study to Assess Adverse Events and Effectiveness of Gel Stent (XEN63) Implantation Using Ab Interno and Ab Externo Approaches in Adult Participants With Glaucoma
Glaucoma is the second most common cause of blindness in the world, second only to cataracts. This study will assess how safe and effective a glaucoma gel stent is when implanted using the ab interno (inside the eye) and ab externo (outside the eye) approach. Adverse events and intraocular pressure will be assessed. XEN63 is an investigational device for the treatment of intraocular pressure (IOP) in patients with glaucoma when both medical and conventional surgical treatments have failed (for US approval) and when medical treatments have failed (for outside US \[OUS\] approval). Participants will be placed in one of two groups called study arms. One group will receive the XEN63 gel stent ab interno (inside the eye) and the other group will receive the XEN63 gel stent ab externo (outside the eye). Approximately 130 participants aged 45 years or older with glaucoma will be enrolled in this study at approximately 32 sites in the United States. Participants will receive XEN63 implanted using either the ab interno approach or the ab externo approach on Day 1 and will be followed for 12 months. Participants will attend regular visits during the study at a hospital or clinic. The safety and effect of the gel stent on your glaucoma will be checked by medical assessments and eye examinations.

• That meets the following refractory glaucoma criteria of eyes diagnosed with glaucoma uncontrolled by maximal medical therapy (four or more classes of intraocular pressure (IOP)-lowering medications, or fewer in cases where it has been documented that certain medication classes cannot be tolerated or are contraindicated), and failed one or more incisional intraocular glaucoma surgeries (e.g., glaucoma filtering surgery, tube shunt)
• Uncontrolled by medical therapy (to meet out-of-US \[OUS\] requirements) with participants who only have glaucoma uncontrolled by medical therapy (non-refractory glaucoma), a maximum of 10 participants who meet only criterion b (and not a) will be enrolled in each cohort.
A Study Investigating Subcutaneously Administered Pozelimab in Combination With Cemdisiran or Cemdisiran Alone in Adult Participants With Geographic Atrophy (SIENNA)
This study is researching experimental (study) drugs called pozelimab and cemdisiran. The study is focused on participants who have Geographic Atrophy (GA) caused by Age-related Macular Degeneration (AMD). Geographic atrophy is a medical term that refers to later-stage cases of AMD which is an eye condition affecting central vision (what one sees straight ahead). The purpose of this study is to evaluate the progression rate of Geographic Atrophy in eyes of patients treated with cemdisiran alone or in combination with pozelimab compared to those treated with placebo. The study is looking at several other research questions, including: * What side effects may happen from taking the study drug(s) * How much study drug(s) are in the blood at different times * Whether the body makes antibodies against the study drug(s) (which could make the study drug(s) less effective or could lead to side effects)

Study to Assess Change in Disease Activity and Adverse Events of Ab Externo Approach for Glaucoma Gel Stent (XEN45) Implantation In Participants Aged 45 Years or Older With Open-Angle Glaucoma
Glaucoma is the second most common cause of blindness in the world, second only to cataracts. This study will assess how safe and effective a glaucoma gel stent is when implanted using the ab externo approach. Adverse events and intraocular pressure will be assessed. XEN45 is an approved device for the treatment of glaucoma implanted using the ab interno approach (inside the eye). XEN45 implanted using the ab externo approach (outside the eye) is being studied in this study. Approximately 65 participants aged 45 years or older with open-angle glaucoma will be enrolled in this study at approximately 22 sites in the United States. All participants will receive XEN45 implanted using the ab externo approach on Day 1 and will be followed for 12 months. Participants will attend regular visits during the study at a hospital or clinic. The safety and effect of the gel stent on your glaucoma will be checked by medical assessments and eye examinations.

• Biopsy-proven non-hematopoietic malignancy, except for small cell lung cancer, germ cell cancer, or unknown primary tumor.
• Radiographic evidence by MRI (or by CT scan with CT contrast if ineligible or intolerant of MRI) of brain metastasis. (If patient is unable to tolerate MRI contrast, an MRI without contrast is acceptable if lesions are visible)
• All brain metastases must be outside the brain stem (midbrain, pons and medulla).
• Patient must have 10 or less brain metastases.
• The maximum diameter of any lesion must be less than or equal to 3.0 cm.
• Previous treatment with surgery, radiation, chemotherapy, immunotherapy or any targeted agents are allowed provided that: * Radiation was not to the brain. * Surgery to the brain was \> 7 days prior to SRS and there remains at least one additional brain metastasis that can be targeted with SRS
• Age ≥ 18 years.
• ECOG Performance Score of 2 or better/Karnofsky Performance Status score of 50-60 or better.
• All men, as well as women of child-bearing potential must agree to use adequate contraception (hormonal or barrier method of birth control; abstinence) prior to study entry and for the duration of study participation. Should a woman become pregnant or suspect she is pregnant while participating in this study, she should inform her treating physician immediately. A female of child-bearing potential is any woman (regardless of sexual orientation, marital status, having undergone a tubal ligation, or remaining celibate by choice) who meets the following criteria: * Has not undergone a hysterectomy or bilateral oophorectomy; or * Has not been naturally postmenopausal for at least 12 consecutive months (i.e., has had menses at any time in the preceding 12 consecutive months).
• Ability to understand and the willingness to sign a written informed consent. Exclusion Criteria
• Patients had craniotomy and surgery to the brain within 7 days from the date of SRS.
• Patients with leptomeningeal metastasis. NOTE: For the purposes of exclusion, LMD is a clinical diagnosis, defined as positive CSF cytology and/or equivocal radiologic or clinical evidence of leptomeningeal involvement. Patients with leptomeningeal symptoms in the setting of leptomeningeal enhancement by imaging (MRI) would be considered to have LMD even in the absence of positive CSF cytology, unless a parenchymal lesion can adequately explain the neurologic symptoms and/or signs. In contrast, an asymptomatic or minimally symptomatic patient with mild or nonspecific leptomeningeal enhancement (MRI) would not be considered to have LMD. In that patient, CSF sampling is not required to formally exclude LMD, but can be performed at the investigator's discretion based on level of clinical suspicion.
• Patients with a contraindication to both MRI (with or without contrast) and CT scan (with contrast)
• Patients with life expectancy \< 3 months.
• Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that, in the opinion of the investigator, would limit compliance with study requirements.
• Subjects must not be pregnant or nursing at the time of SRS treatment due to the potential for congenital abnormalities and the potential of this regimen to harm nursing infants.

The Longitudinal CONQUER Study of Rare Neuroimmunologic Disorders
This study seeks to determine the biologic causes of inflammation in patients with Transverse Myelitis (TM) Neuromyelitis Optica Spectrum Disorder (NMOSD) and related conditions. While patients will be treated according to decisions with their treating physician, this study will collect data and samples from patients prospectively to gain a better understanding of the disease. We are seeking to understand why some patients respond to medications, while others do not. We also seek to understand what happens biologically, preceding relapses. Gathering these data and samples will allow researchers to identify new ways of diagnosing and treating these diseases. Data and samples will be shared with researchers around the world to support collaborative efforts to treat these conditions.

Intacs for Keratoconus
The US food and Drug Administration (FDA) originally approved INTACS prescription inserts in April 1999 for the correction of low levels of nearsightedness (-1.00 to -3.00 diopters). Additional clinical data have shown that INTACS are safe for the treatment of keratoconus, in July 2004, FDA approved INTACS inserts for the treatment of keratoconus as a Humanitarian Use Device (FDA approval letter attached). The statute and the implementing regulation of FDA (21 CFR 814.124 (aj) require IRB review and approval before a HUD is used.INTACS prescription inserts are composed of two clear segments, each having an arc length of 150°, they are manufactured form a biomedical material called polymethylmethacrylate (PMMA) and are available in three thicknesses. Two INTACS inserts ranging from 0.250mm to 0.350mm may be implanted depending on the orientation of the cone and the amount of myopia and astigmatism to be reduced.
