Outcomes of Zone 3 Open Globe Injuries by Wound Extent: Subcategorization of Zone 3 Injuries Segregates Visual and Anatomic Outcomes.

ABSTRACT:

Purpose

Open globe injuries (OGIs) are categorized by zone, with zone 3 (Z3) comprising wounds > 5 mm beyond the limbus. Outcomes of Z3 OGIs are highly heterogeneous. Open globe injuries with far posterior Z3 (pZ3) wounds were hypothesized to have worse visual and anatomic outcomes.

Design

Single-center retrospective cohort study.

Participants

A total of 258 eyes with Z3 OGIs.

Methods

A retrospective review of Z3 OGIs treated at a tertiary center over 12 years. Wounds ≥ 10 mm posterior to the limbus were defined as pZ3. Outcomes were compared between pZ3 and anterior Z3 (aZ3) eyes.

Main outcome measures

Visual acuity on a logarithm of the minimum angle of resolution (logMAR) scale. Secondary outcomes included anatomic outcomes, development of retinal det
