Macular function of successfully repaired macula-off retinal detachments

Area of Science:

• Ophthalmology
• Retinal Surgery
• Visual Neuroscience

Background:

• Macular function is critical for visual acuity.
• Retinal detachment (RD) can lead to significant vision loss.
• Surgical repair aims to restore vision, but long-term outcomes are variable.

Purpose of the Study:

• To assess long-term macular function after successful macula-off RD repair.
• To investigate the relationship between detachment duration and functional recovery.

Main Methods:

• Evaluated 29 patients with unilateral macula-off RD and ≥6 months follow-up.
• Compared operated eyes (Group I) with fellow eyes (Group II).
• Assessed visual acuity, contrast sensitivity, color vision, visual field, and visual evoked potentials (VEPs).

Main Results:

• Macular functions, except P100 amplitudes, were significantly poorer in operated eyes after ~5 years.
• Longer duration of macular detachment correlated with smaller improvements in visual acuity, contrast sensitivity, and color vision.
• No significant correlation found between detachment duration and visual field mean deviation or VEP parameters.

Conclusions:

• Macular functions, excluding P100 amplitude, show incomplete recovery 5 years post-retinal reattachment.
• Prolonged macular detachment duration adversely affects visual recovery outcomes.
• VEP parameters and visual field indices showed less correlation with detachment duration compared to other functional measures.
