64% and 100%, respectively, for any ROP and 9.88% and 100% for severe ROP.<br /><br /> One-time only calculation of the ROPScore algorithm could identify severe cases after validation, reducing the number of screened infants by 38% in infants with a birth weight of 1,500 g or less or a gestational age of 32 weeks or younger.

[J Pediatr Ophthalmol Strabismus. 2021;58(1)55-61.].<br /><br /> To address the knowledge gap regarding the actual acuity requirements needed in typical kindergarten through grade 12 classrooms by determining an actual logarithm of the minimum angle of resolution (logMAR) and contrast sensitivity requirements in a sample of classrooms for kindergarten through grade 12 in New York City.<br /><br /> Measurements of classroom dimensions with specific attention to viewing distances were made in public and private school classrooms, at various grade levels from kindergarten through grade 12, in New York City. The dimensions of typical text shown to students on classroom smartboards and whiteboards was measured and the mean and range of logMAR values were calculated for various seating locations within the classrooms. Contrast between text and background was estimated by comparing digital images of actual classroom text to Pelli-Robson contrast sensitivity charts.<br /><br /> Fourteen classrooms in five schools were evaluated. Classroom dimensions varied from 8 × 10 feet to 23 × 23 feet. Mean loglities. [J Pediatr Ophthalmol Strabismus. 2021;58(1)48-54.].<br /><br />The data reveal that logMAR demands and contrast vary substantially from classroom to classroom and within a classroom based on room dimensions and seating. Although generally supporting current acuity-based pediatric vision screening referral guidelines, the data also provide insight into the potential impact of reduced visual acuity and seating location on visual performance in the classroom. These findings suggest the need to develop logMAR and contrast standards that optimize visual content in classrooms while accommodating a wider range of visual capabilities.

Twelve and 6 patients had lower and upper canalicular tear, respectively. Six (33.4%) patients had associated ocular comorbidity. The common mode of trauma was direct injury in 77.8% of the patients. The blouse hook of the mother was noted as the most common object causing canalicular laceration. Early repair (&lt; 48 hours) and delayed repair were done in 7 (38.9%) and 11 (61.1%) patients, respectively. Anatomical and functional success was achieved in 88.9% and 94.4% of patients, respectively. The odds ratio (95% CI) for anatomical and functional success with the time since injury was 0.6 (CI 0.03 to 11.47) and 0.19 (CI 0.01 to 5.33), respectively. There was no significant difference between the early and delayed repair groups in terms of the distribution of anatomical (P = 1.000) and functional (P = .389) success. There was no significant difference between the various groups in terms of the distribution of complications (P = .224).<br /><br /> Canalicular laceration repair with the Mini Monoka stent in children younger than 10 years has shown good outcomes in terms of anatomical and functional success irrespective of time lag since injury to repair.

[J Pediatr Ophthalmol Strabismus. 2021;58(1)42-47.].<br /><br /> To compare the results of surgery for constant and intermittent exotropia, to determine factors affecting surgical success, and to evaluate the effect of horizontal rectus muscle surgery on distance-near incomitance.<br /><br /> In this retrospective study of 291 Scandinavian patients, inclusion criteria were surgery for constant (n = 101) or intermittent (n = 190) exotropia with no vertical deviation, no previous strabismus surgery, and available postoperative follow-up data. Medical records of patients (age 3 to 85 years) undergoing surgery were reviewed. Surgical success was defined as postoperative esodeviation of less than 5 prism diopters (PD) to exodeviation of 10 PD or less.<br /><br /> Surgical success was 70% in constant exotropia and 80% in intermittent exotropia (P &gt; .05). At follow-up 1.5 years after surgery, a significant drift was found in intermittent exotropia (P &lt; .05). Different surgeons, spherical equivalents, anisometropia, amblyopia, gender, and age had no effect on surgical success (P &gt; .05). Thutcome. A distance-near incomitance may be an important consideration in choosing the magnitude of medial versus lateral rectus muscle surgery. [J Pediatr Ophthalmol Strabismus. 2021;58(1)34-41.].<br /><br /> To investigate the effect of the gaze fixation position on measurement of the limbus and extraocular muscle (EOM) insertion site distance using anterior segment optical coherence tomography (AS-OCT).<br /><br /> Patients undergoing horizontal EOM surgeries were enrolled in this prospective experimental study. The distance between the angle recess and the muscle insertion site was measured using AS-OCT while patients fixed their gaze laterally or medially at inner or outer gaze fixation. The distance between the limbus and muscle insertion was intraoperatively measured using calipers.<br /><br /> A total of 46 lateral rectus muscles and 36 medial rectus muscles of 44 patients were evaluated. Significant differences were observed between intra-operative measurements (6.3 ± 0.7 mm) and AS-OCT measurements (5.8 ± 0.7 mm) for the lateral rectus muscle at inner gaze fixation (P = .0017) and medial rectus muscle at outer gaze fixation (P = .0003); no difference was observed when the lateral rectus (6.4 ± 0.5 mm) and medial rectus (4.
