Brief summary

Purpose: To analyze the clinical benefits of using the NGENUITY 3D Visualization System in vitreoretinal surgery with low levels of endo-illumination, focusing on functional and structural retinal protection in patients with idiopathic epiretinal membranes (ERM). Design: Prospective, randomized, comparative study. Methods: Forty pseudophakic patients (29♀, 11♂; age 60-80 years) with ERM underwent 27G pars plana vitrectomy (PPV) and were randomly divided into two groups: Group I (20 eyes, stand-ard microscope \[Hi-R 900\], endo-illumination 3.2 Lm) and Group II (20 eyes, 3D heads-up NGE-NUITY system, endo-illumination 0.5 Lm). Preoperative and 6-month postoperative evaluations included slit-lamp examination, intraocular pressure (IOP, Pascal tonometer), Distance Best Correct-ed Visual Acuity (DBCVA, logMAR), Central Subfield Thickness (CST), Retinal Nerve Fiber Layer Thickness (RNFL, OCT), Pattern ERG (PERG), multifocal ERG (mfERG), flash ERG (ERG, IS-CEV standards), and retinal sensitivity (HFA macula test). Surgery time, xenon light exposure, ERM/ILM peeling time, fundus autofluorescence (FAF), metamorphopsia incidence, and intra-/postoperative adverse events were analyzed. Results were statistically evaluated (p \< 0.05).

Design outcomes

Primary

MeasureTime frameDescription
Bioelectrical Retinal function6 monthsThe low intensity of endoillumination (0.5 Lm) utilized in PPV with the NGENUITY 3D system may reduce retinal phototoxicity compared to the higher intensity of light (3.2 Lm)

Secondary

MeasureTime frameDescription
Structural Macula Changes6 monthsThe low intensity illumination may be a cause of reduced macular structure changes
Changes DBCVA (Distance Best Corrected vision)6 monthsThe low intensity illumination may be a cause of beter DBCVA after surgery
