Purpose: To subjectively evaluate the degree of visual fatigue in children attending online classes during the coronavirus 2019 (COVID-19) pandemic and objectively evaluate accommodation and vergence dysfunction in these children. Methods: Children aged between 10 and 17 years with recent onset of asthenopia symptoms were included. Symptoms were evaluated using the Convergence Insufficiency Symptom Survey (CISS) questionnaire. A CISS score of 16 or greater was considered symptomatic. Binocular vergence and accommodation parameters were objectively evaluated. For ease of comparison, children were divided into two groups: children using digital devices for less than 4 hours/day and children using digital devices for 4 hours/day or more. Results: A total of 46 children with a mean age of 14.47 ± 1.95 years were evaluated. The mean duration of online classes during the COVID-19 pandemic was 3.08 ± 1.68 hours/day, which is higher than before the COVID-19 pandemic (0.58 ± 0.71 hours/day, P <.00001). The mean CISS scores were 21.73 ± 12.81 for children using digital devices less than 4 hours/day and 30.34 ± 13.0 for children using digital devices for 4 hours/day or more (P =.019). Mean near exophoria (P =.03), negative fusional vergence (P =.02), negative relative accommodation (P =.057), and accommodation amplitude (P =.002) were different between the two groups. The Spearman correlation between the symptomatic CISS score and the duration of online classes showed a linear association (coefficient rs = 0.39; P =.007). In the multivariate analysis, only the duration of online classes longer than 4 hours was a significant risk factor (P =.07) for the symptomatic CISS score. Conclusions: Online classes longer than 4 hours were more detrimental to abnormal binocular vergence and accommodation parameters than online classes shorter than 4 hours.

Purpose: To compare the safety, feasibility, and outcomes of clear corneal cataract surgery with or without sutures in children (2 to 8 years old) with congenital or developmental cataracts. Methods: One hundred seventy consecutive eligible eyes with pediatric cataracts were randomized into treatment groups depending on closure of clear corneal incisions: suture group and sutureless hydroclosure group (sutureless group). Patients were evaluated on days 1, 7, 30, and 90 postoperatively, with an emphasis on wound leakage from incisions and complications. Results: Wound leakage from any corneal incisions was not observed in both groups. Shallow anterior chamber on the first postoperative day was observed in 2 and 3 eyes in the suture and sutureless groups, respectively (P =.48). Hypotony was not observed in any patients. Intraocular pressure measurements were comparable on follow-up visits (P >.05). Mean cylindrical error was significantly greater (P =.03) in the suture group than the sutureless group (1.01 and 0.74 diopters, respectively) after 1 month. One patient developed endophthalmitis after suture removal in the suture group. Conclusions: Sutureless hydroclosure of incisions is not inferior compared to suturing in pediatric cataracts. This avoids suture-related complications while reducing the astigmatic error and is thus potentially less amblyogenic. However, sutures must be used whenever the incision architecture is compromised.

Purpose: To determine the surgical outcomes of bleb needling and the risk factors of failure of needling after failed filtration surgeries in patients with pediatric glaucoma. Methods: The medical records of patients who underwent needling with 5-fluorouracil following filtering surgeries (trabeculectomy, combined trabeculectomy, and trabeculotomy) between January 2012 and December 2016 were retrospectively reviewed. At the 1-year follow-up visit, complete success and qualified success were defined as an intraocular pressure (IOP) of less than 18 mm Hg with and without antiglaucoma medication, respectively. Results: Forty-five eyes that underwent needling and fulfilled the study criteria were included in the analysis. The mean age at needling was 9.6 years. The mean time interval between filtration surgery and the first needling procedure was 57.3 days. Thirty-eight of 45 eyes (84.4%) had undergone needling within 3 months after the primary surgery. Cumulative success was achieved in 35 eyes (77.7%) after needling (complete success in 22 eyes and qualified success in 13 eyes). Mean follow-up after needling was 18.9 months. The mean IOP before and after needling was 31.7 ± 9.45 and 16.6 ± 5.68 mm Hg, respectively (P <.00001). Steroid-induced glaucoma (P =.01), high IOP prior to the first filtration surgery (P =.01), and an inability to achieve low IOP (< 9 mm Hg, P =.04) immediately after needling were significant risk factors associated with failure. Conclusions: Bleb needling is an efficient method for lowering IOP after a failed trabeculectomy or combined trabeculectomy and trabeculotomy in the pediatric population.

Purpose: To evaluate demographic data, clinical profile, and factors responsible for the success of anatomical and functional outcomes of canalicular laceration repair with the Mini Monoka stent (FCI Ophthalmics) in children younger than 10 years. Methods: This was a retrospective cohort observational study involving children younger than 10 years who underwent canalicular tear repair with the Mini Monoka stent with a minimum follow-up of 6 months. Results: A total of 18 patients (9 boys and 9 girls) with a mean age of 5.39 ± 3.05 years were included. 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 (< 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 (A total of 18 patients (9 boys and 9 girls) with a mean age of 5.39 ± 3.05 years were included.

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). Conclusions: 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.

Purpose: To evaluate the safety and efficacy of surgical membranectomy with a vitrector via a limbal approach for posterior capsular opacification (PCO) in children. Methods: In this retrospective analytical interventional study, medical records of children younger than 17 years who underwent surgical membranectomy with anterior vitrectomy via a limbal approach were analyzed. Time lag for PCO formation after cataract surgery was assessed. Any adverse events during surgery, rate of successful completion of membranectomy, postoperative complications, improvement in visual acuity, and intraocular lens (IOL) centration were recorded. Results: A total of 60 eyes of 58 children were included: 26 had traumatic etiology and 34 had developmental cataract. Mean time duration for PCO formation was 27.83 ± 39.83 months for traumatic cases and 53.53 ± 52.20 months for developmental cataract (A total of 60 eyes of 58 children were included: 26 had traumatic etiology and 34 had developmental cataract. Mean time duration for PCO formation was 27.83 ± 39.83 months for traumatic cases and 53.53 ± 52.20 months for developmental cataract (P =.04). A satisfactory opening in the center of the membrane was achieved in 47 cases (n = 47, 78.3%). The complications encountered were uveitis (5 eyes), corneal edema (3 eyes), pigment deposition over IOL (2 eyes), raised intraocular pressure (1 eye), IOL drop (1 eye), and broken haptic (1 eye). Membranectomy with posterior optic buttonholing of the IOL in 9 aphakic eyes resulted in good IOL centration, no anterior chamber reaction, and no iris optic capture in the postoperative period. Mean visual acuity improved from 1.16 ± 0.52 to 0.73 ± 0.55 logMAR (P <.001). Conclusions: Surgical membranectomy with a vitrector via a limbal approach is a safe and effective method for managing PCO in the pediatric population. Posterior optic buttonholing of the IOL during membranectomy or secondary IOL implantation results in good IOL centration and fewer complications.

The authors report a rare case of slipped medial rectus muscle with stretched scar in the left eye of a 45-yearold woman following pterygium surgery. There was total limitation of adduction in her left eye with complaints of diplopia in all gazes with maximum separation of images in dextroversion on diplopia charting. Hess charting showed underaction of the medial rectus muscle of the left eye and overaction of the lateral rectus muscle of the right eye. Based on the history and findings, a diagnosis of medial rectus muscle disinsertion of the left eye during pterygium surgery was made. Medial rectus muscle exploration was done and the slipped medial rectus muscle was found attached to its original insertion site via pseudotendon/stretched scar. The capsule was dissected, the scar tissue was excised, and the slipped medial rectus muscle was identified, hooked, and secured with sutures. The muscle was reattached with advancement. Postoperatively, the patient was orthotropic and there was no diplopia. Accidental medial rectus muscle disinsertion during pterygium surgery is a rare but serious complication. Proper care should be taken intraoperatively during pterygium surgery to avoid this complication. However, meticulous surgical exploration and reattachment of the muscle yields satisfactory results.
