“…[21] Myopia was the predominant refractive error and was present in 47.2% cases of which high myopia constituted about 27.8 % cases similar to other studies. [14] [22] Most preterm infants have with the rule astigmatism [23] similar to our study. Gunay demonstrated significantly higher rates of strabismus following laser treatment compared to IVB monotherapy.…”

“…Laser treatment has been well-described as a cause of advanced refractive errors in severe cases of ROP (27,28) . Conversely, studies have reported IVB treatment leads to lower degrees of myopic refraction than laser ablation.…”

Approved by the following research ethics committee: Zeynep Kamil Maternity and Children's Disease Training and Research Hospital. ABSTRACTPurpose: To evaluate 2-year outcomes following intravitreal bevacizumab (IVB) as monotherapy for aggressive posterior retinopathy of prematurity (APROP). Methods: Medical records of 40 infants were retrospectively reviewed. Group I included infants who had received IVB injections for APROP. Group II included infants who underwent laser treatment for APROP. Anatomic and refractive outcomes and the presence of anisometropia and strabismus were assessed at follow-up examinations. Results: Group I included 48 eyes of 25 infants (11 males) with a mean gestational age (GA) of 26.40 ± 1.82 weeks and a mean birth weight (BW) of 901.40 ± 304.60 g. Group II included 30 eyes of 15 infants (6 males) with a mean GA of 27.30 ± 1.82 weeks and a mean BW of 941.00 ± 282.48 g. GA, BW, and gender distributions were similar between groups (P=0.187, P=0.685, and P=1.000, respectively). Refractive errors were significantly less myopic in group I (0.42 ± 3.42 D) than in group II (-6.66 ± 4.96 D) at 2 years (P=0.001). Significantly higher rates of anisometropia and strabismus were observed in group II than in group I (P=0.009 and P=0.036, respectively). Conclusions:The study demonstrated that IVB monotherapy can be useful in the treatment of APROP. The decreased incidence of early unfavorable refractive and functional outcomes in the IVB group compared with the laser group showed a potential benefit for patients treated with IVB, and this needs to be better evaluated in future prospective studies.

“…At the first ophthalmic examination, the eyes of high-risk premature infants were screened at postnatal age of 4-6 weeks under indirect ophthalmoscope. 9,10,11 The stage and severity of ROP was classified according to the International Classification of ROP. 12 Threshold disease of ROP was defined by the Cryotherapy for Retinopathy of Prematurity Cooperative Group (CRYO-ROP study) as Z5 contiguous or 8 cumulative clock-hours of extraretinal neovascularization stage 3 ROP and associated with plus disease within zones I or II.…”

Purpose To assess the prevalence of astigmatism and its relationship with biometric optic components in preterm school children with diode laser-treated threshold retinopathy of prematurity (ROP). Methods A prospective, cross-sectional study in which cycloplegic keratometry, refraction, and ultrasound biometric measurement of optic components were performed on 24 consecutive preterm children with diode laser-treated threshold ROP at the age of 9 years. The study results were compared with data on 1021 agematched full-term control children from a national survey. Results The laser-treated eyes had a mean astigmatism of 3.47 D, with a mean spherical equivalent of À 4.49 D. Of the 46 eyes studied, 98% of eyes showed astigmatism Z0.5 D and 50% had high astigmatism (43.0 D). Most astigmatic eyes (97.7%) showed with-the-rule astigmatism, with the mean plus cylinder axis at 89.30 o . Further correlation analysis showed the astigmatism in refraction was highly correlated with the corneal astigmatism (r ¼ 0.921, Po0.001) and the vertical corneal curvature (r ¼ 0.405, P ¼ 0.005). There was significantly steeper vertical corneal curvature (P ¼ 0.003) and flatter horizontal corneal curvature (P ¼ 0.031) in eyes with laser-treated ROP when compared with age-matched full-term controls. The eyes with laser-treated ROP also show significantly thicker lens (3.93 mm) and shallower anterior chamber depth (ACD; 2.92 mm) than full-term controls (Po0.001). Conclusions There is significantly higher prevalence and greater magnitude of astigmatism in eyes with laser-treated threshold ROP compared with full-term controls. The steeper vertical corneal curvature component contributes to the increased astigmatism in eyes with laser-treated ROP.
