USE OF HAND-HELD OPTICAL COHERENCE TOMOGRAPHY DURING RETINOPATHY OF PREMATURITY SCREENING DEMONSTRATES AN INCREASED OUTER RETINA FROM EARLY POSTMENSTRUAL AGE IN PRETERM INFANTS WITH RETINOPATHY OF PREMATURITY

imagePurpose:

To identify structural markers of active retinopathy of prematurity (ROP) in foveal and parafoveal retinal layers using hand-held optical coherence tomography.

Methods:

Hand-held optical coherence tomography images (n = 278) were acquired from a prospective mixed cross-sectional longitudinal observational study of 87 participants (23–36 weeks gestational age; n = 30 with ROP, n = 57 without ROP) between 31 and 44 weeks postmenstrual age excluding treated ROP and features of cystoid macular edema. Six retinal layer thicknesses from the fovea to the parafovea were analyzed at five locations up to 1,000 µm, temporally and nasally.

Results:

The mean outer retinal thickness during active ROP increased at the fovea and parafovea from postmenstrual age 33 weeks to 39 weeks (P

CONTRIBUTION FACTORS OF EFFECTIVE LENS POSITION, TILT, AND DECENTRATION DURING FLANGED SCLERAL FIXATION OF INTRAOCULAR LENS: A Model Eye Study

imagePurpose:

The authors aimed to elucidate the factors related to effective lens position, tilt, and decentration of scleral fixed intraocular lenses (IOLs) with a flanged haptic technique in an artificial eye model using anterior segment optical coherence tomography.

Methods:

Two bent 27-gauge needles were passed through a 1.0- or 2.0-mm scleral tunnel, 2.0 mm posterior to the limbus and 180° apart. Both haptics of a three-piece IOL were docked with guide needles and externalized. Factors related to the IOL position were analyzed using anterior segment optical coherence tomography and a stereomicroscope.

Results:

The 1.0-mm scleral tunnel induced a significantly longer effective lens position than the 2.0-mm tunnel and suture fixation (P

MACULAR CHORIORETINAL ATROPHY AND VISUAL OUTCOMES IN RANIBIZUMAB- OR AFLIBERCEPT-TREATED MYOPIC CHOROIDAL NEOVASCULARIZATION

imagePurpose:

To investigate the predictors of macular chorioretinal atrophy, consisting of patchy atrophy (PA) at the macula and choroidal neovascularization (CNV)-related macular atrophy (CNV-MA), during treatment with ranibizumab or aflibercept for myopic CNV (mCNV) and its impact on visual outcomes.

Methods:

This retrospective study included 82 eyes with treatment-naïve mCNV who were treated with pro re nata injections of ranibizumab or aflibercept.

Results:

Nine eyes (11.0%) presented with macular PA at baseline (PA group), and 73 eyes (89.0%) did not (non-PA group). VA improved during the first year in the non-PA group; a similar trend was noted in the PA group until 3 months after initial treatment. This improvement was maintained until 24 months (P
