To determine the refractive outcomes of eyes treated with three–port lens–sparing vitrectomy (LSV) for Stage 4A tractional retinal detachments due to Retinopathy of Prematurity (ROP) as compared to fellow eyes that underwent laser photocoagulation alone.
In a retrospective study, the records of 18 eyes of 9 patients presenting with unilateral stage 4A retinal detachment that underwent a primary LSV (group 1) and laser treated disease in the fellow eye (group 2) secondary to ROP from February 1998 to January 2004 were evaluated. Main outcome measures included refraction, keratometry, and A–scan values for axial length, lens thickness, lens position, anterior chamber depth, anterior segment depth, and lens power calculations.
Mean spherical equivalents were –6.50 diopters for the LSV group (group 1) and –10.50 diopters for the laser photocoagulation group (group 2) (P < 0.01). Decreased myopia in the LSV group was associated with deeper anterior chamber depth and more posterior lens position as compared to group 2. No statistical significance was noted between these groups in terms of the other factors.
Lens–sparing vitrectomy may induce less myopia than control eyes perhaps due to posterior lens displacement and increased anterior chamber depth.
