Functional macular mapping in patients with vitreomacular pathologic features before and after surgery

Area of Science:

• Ophthalmology
• Retinal Surgery
• Visual Function Assessment

Background:

• Macular hole and macular pucker are conditions affecting central vision.
• Surgical interventions aim to restore visual function in these patients.
• Objective documentation of visual performance is crucial for evaluating surgical success.

Purpose of the Study:

• To assess the utility of microperimetry and preferential hyperacuity perimeter (PHP) in objectively measuring visual performance changes.
• To compare the sensitivity of these tools in detecting improvements after macular surgery for macular hole and pucker.

Main Methods:

• An observational case series involving 19 patients with macular holes and 18 with macular pucker.
• Best-corrected visual acuity (BCVA), central retinal sensitivity via MP1 microperimetry, and metamorphopsia using PreView-PHP were recorded pre- and post-surgery (4 and 12 weeks).
• Key metrics included mean sensitivity (dB) and fixation stability from microperimetry.

Main Results:

• Both BCVA and microperimetry demonstrated significant improvements 12 weeks post-surgery.
• A higher proportion of patients showed improvement in microperimetry results (68.4% macular hole, 77.8% macular pucker) compared to BCVA (47.3% macular hole, 66.7% macular pucker).
• PHP did not reveal significant changes in scotomas or metamorphopsia.

Conclusions:

• Microperimetry provides a more comprehensive assessment of functional visual recovery than BCVA alone after macular surgery.
• Functional macular mapping using microperimetry is valuable for these patients.
• BCVA may underestimate the true functional benefits achieved through surgery for macular conditions.
