A Study of the Incidence of Intraocular Inflammation and Suspected Endophthalmitis Among Patients Treated With Aflibercept, Vial and Pre-filled Syringe, 2014-2022

Specific study objectives include:

* To describe patient and provider characteristics for aflibercept patients and aflibercept user injections by aflibercept dispensing device, overall, and stratified by time (quarterly, annually). * To estimate the annual and quarterly incidence of intraocular inflammation (IOI) and suspected endophthalmitis for aflibercept user injections by aflibercept dispensing device.

Secondary objectives

• To estimate the annual incidence of IOI and suspected endophthalmitis for aflibercept user injections by dispensing device, stratified by indication for use, history of IOI, and provider characteristics.

Key information

About this study

This study is entirely descriptive using secondary data from the Vestrum Health Retina Treatment and Outcomes database.

Who can participate

Healthy volunteers accepted: No

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

for a Treatment Episode:

  • Must have received one or more injections of aflibercept, regardless of indication, between 01Jan2014 to 30Apr2022
  • Patients must have at least one eligible treatment episode a. Specification of laterality of aflibercept injection (left or right eye or both) for treatment episode

Exclusion criteria

for a Treatment Episode:

  • A post-operative follow-up visit for any ocular surgery (excluding vitrectomy), within +/-28 days of aflibercept injection, as defined in the protocol
  • Active steroid treatment, defined as steroid treatment (topical or intravitreal) on the date of aflibercept injection. This criterion is limited to date of aflibercept injection since steroids may be used to treat IOIs.
  • Any treatment episode where a patient eye receives >1 (or an unknown) anti-VEGF injection on the index date (date of aflibercept injection).

Primary outcomes

  1. Frequency of patients receiving aflibercept injections

    Time frame: End of Study, Approximately 8 Years

  2. Frequency of aflibercept injections by ophthalmic delivery mechanism

    Time frame: End of Study, Approximately 8 Years

    Ophthalmic delivery mechanism defined as prefilled syringe (PFS) and vial

  3. Incidence of Intraocular inflammation (IOI)

    Time frame: End of Study, Approximately 8 Years

    Incidence will be defined as the number of events during the at-risk period divided by the total number of injections, identified using international classification of diseases (ICD-9 and ICD-10) diagnosis codes.

  4. Incidence of Intraocular inflammation (IOI) by ophthalmic delivery mechanism

    Time frame: End of Study, Approximately 8 Years

    Incidence will be defined as the number of events during the at-risk period divided by the total number of injections, identified using international classification of diseases (ICD-9 and ICD-10) diagnosis codes.

    Ophthalmic delivery mechanism defined as prefilled syringe (PFS) and vial

  5. Incidence of suspected endophthalmitis

    Time frame: End of Study, Approximately 8 Years

    Incidence will be defined as the number of events during the at-risk period divided by the total number of injections, identified using international classification of diseases (ICD-9 and ICD-10) diagnosis codes.

  6. Incidence of suspected endophthalmitis by ophthalmic delivery mechanism

    Time frame: End of Study, Approximately 8 Years

    Incidence will be defined as the number of events during the at-risk period divided by the total number of injections, identified using international classification of diseases (ICD-9 and ICD-10) diagnosis codes.
