Purpose

To assess long-term functional and structural outcomes in eyes treated with laser photocoagulation for retinopathy of prematurity (retinopathy of prematurity).

Methods

Treated for retinopathy of prematurity (1997-2004) underwent best-corrected visual acuity (BCVA) assessment, autorefraction, biometry, OCT, and OCT angiography of the macula and optic disc.

n = 33 patients

Results

0.133

logMAR

this number means patients had good vision, measured with their best corrective lenses

n = 33 patients

More results

Poor anatomical outcome occurred in 6.3% (n = 4), with 2 eyes requiring surgery.

Mean spherical equivalent was -5.04 (±5.13) D.

Corneal curvature and lens thickness were significantly higher in the study group (p < .001).

More results

Central macular thickness was greater in retinopathy of prematurity eyes (311.97 μm vs 252.57 μm; p < .001).

Conclusion · 1 of 2

Two decades after laser treatment, our patients demonstrated excellent visual acuity and favourable anatomic outcomes. Myopia was linked to increased corneal curvature and lens thickness.

Conclusion · 2 of 2

Significant alterations in the vascular plexuses of the macula and optic disc occur and may impact visual function in adulthood.
