ACUTE- AND DELAYED-ONSET ENDOPHTHALMITIS AFTER OPEN GLOBE INJURIES: Clinical Features and Visual Acuity Outcomes

imagePurpose:

The purpose of the study was to report the clinical features and best-corrected visual acuity outcomes in patients with acute- and delayed-onset endophthalmitis after open globe injuries.

Methods:

The study included a retrospective, comparative, consecutive case series of patients with endophthalmitis after open globe injury between January 2016 and October 2020 at the Bascom Palmer Eye Institute.

Results:

Acute-onset endophthalmitis accounted for 16 of 20 cases (80%), and all cases were diagnosed at the initial examination. Delayed-onset endophthalmitis cases, occurring more than 2 weeks after injury, accounted for 4 of 20 cases (20%) and were because of Zone 1 wound leaks and infections. Factors associated with endophthalmitis included presence of a retained intraocular foreign body (11/20 [55%]) and delay of presentation >24 hours (15/20 [75%]) (P

POSTERIOR SCLERAL INDENTATION IN LONG AXIAL LENGTH EYES (AXIAL LENGTH MORE THAN 34 mm) TO ASSIST IN PARS PLANA VITRECTOMY AND INTERNAL LIMITING MEMBRANE PEELING IN FULL-THICKNESS MACULAR HOLES

Purpose:

To assess a novel surgical technique to perform macular surgery in high myopic eyes, with axial lengths >34 mm, where standard-size intravitreal surgical instruments cannot reach the retinal surface during pars plana vitrectomy for interna…

CHARACTERISTICS OF THE MACULAR MICROVASCULATURE IN IDIOPATHIC EPIRETINAL MEMBRANE PATIENTS WITH AN ECTOPIC INNER FOVEAL LAYER

imagePurpose:

To identify the characteristics of the retinal microvasculature in epiretinal membrane patients with ectopic inner foveal layer (EIFL).

Methods:

Patients were classified into two groups: those without EIFL (Group 1) and those with EIFL (Group 2). The vessel density (VD), perfusion density (PD), and the foveal avascular zone (FAZ) parameters were compared using optical coherence tomography angiography. Linear regression analysis was performed to identify the optical coherence tomography angiography parameters associated with best-corrected visual acuity.

Results:

The VD of the central area in Group 1 and Group 2 was 11.6 ± 3.3 and 17.2 ± 2.8 mm−1, respectively (P

RONA Technique: A Novel ILM Peeling Method for Treatment of Large Full-Thickness Macular Holes

imagePurpose:

To present a new technique, RONA, for internal limiting membrane peeling and show its comparable success rate in closure of large full-thickness macular holes (FTMHs).

Methods:

This prospective interventional case series was implemented from January 2018 to November 2019. Consecutive cases with large FTMH with an aperture size of more than 500 μm were included. The RONA technique was used to make consecutive flaps; the central border of which remained adherent to the FTMH edge. The emphasis is that the central border of all flaps should remain adherent to the FTMH edge, letting the flaps remain there spontaneously.

Results:

Seventeen eyes of 17 patients (4 males and 13 females; age 62.3 ± 7.8 years) were included. The mean size of opening and base of FTMH were 651.1 ± 141.1 μm (range: 501–950) and 964.6 ± 383.8 μm (range: 527–2098), respectively. One week after the surgery, complete closure of all FTMHs occurred with no hole reopening until the end of 12 months. The mean best-corrected visual acuity at baseline and 12 months after surgery were 1.57 ± 0.30 and 0.75 ± 0.028 logarithm of the minimum angle of resolution, respectively, with statistically significant improvement (P

CLINICAL CHARACTERISTICS AND SURGICAL PROGNOSIS OF IDIOPATHIC MACULAR HOLES WITH EPIRETINAL PROLIFERATION

imagePurpose:

To investigate the clinical features and surgical outcomes of idiopathic macular holes with epiretinal proliferation (EP).

Methods:

This retrospective study included 282 eyes of 269 consecutive patients who underwent vitrectomy for idiopathic macular holes. Clinical demographic data, baseline and postoperative retinal microstructure features on optical coherence tomography images, best-corrected visual acuity, and postoperative closure rate were compared between eyes with and without EP.

Results:

EP was identified in 38 of 282 eyes (13.5%). Eyes with EP had a significantly longer symptom duration (P = 0.019), higher frequency of pseudophakic conditions (P = 0.034), presence of epiretinal membrane (P
