Cross-sectional study of education and knowledge of unintentional injury prevention and postinjury response given by the parents or caregivers of children in Malvani slum area of Mumbai Suburban District, India.

BACKGROUND: Child injuries significantly impact health and development, shaping the nation's future. With proper knowledge, parents or primary caregivers can effectively prevent, address, and treat these predictable injuries. METHODS: Face-to-face interviews were conducted with 373 parents or primary caregivers of children under 14 years old in four randomly selected urban slum areas in Malwani, Mumbai Suburban District. RESULTS: Only 30% of respondents had basic first aid knowledge, and merely 10% were aware of unintentional injuries, correlating significantly with parental literacy levels. However, most respondents demonstrated appropriate responses. CONCLUSIONS: Parental or primary caregiver knowledge and response play a critical role in mitigating unintentional child injuries. Increasing awareness among parents and primary caregivers about injuries, their impact on child development and first aid is imperative.

Clinical and ASOCT evaluations of 'bleb-sparing epithelial exchange' in paediatric and adult dysfunctional blebs over 5 years.

PURPOSE: To evaluate the long-term outcome of 'bleb-sparing epithelial exchange' surgery for dysfunctional filtering blebs in paediatric and adult eyes. METHODS: Patients who had undergone bleb revision ≥ 5 years back and were on regular follow-up were included. Age, ocular diagnosis, details of primary filtering surgery including mitomycin-C (MMC) usage, indication and year of bleb revision were recorded. After bleb revision, the mean intraocular pressure (IOP), glaucoma medications and best corrected visual acuity (BCVA) up to 5 years were noted. On last review, clinical details, bleb characteristics and swept source anterior segment tomographic (SSOCT) assessment of bleb were recorded. Comparative analysis of paediatric and adult eyes was performed. MAIN OUTCOME MEASURES: Change in IOP and BCVA. 'Complete success' was defined as IOP ≥ 6 to ≤ 18mmHg without use of any topical glaucoma medications and 'Qualified success' when ≥ 1 topical glaucoma medication(s) was required. RESULTS: A total of 51 eyes of 51 consecutive patients were studied, among which 22 were children. The mean duration between filtering surgery and bleb revision was 4.54 ± 1.53 years in paediatric and 6.48 ± 3.5 years in the adult group, p = 0.04. Children underwent trabeculotomy + trabeculectomy with 0.04% MMC, while adults underwent trabeculectomy with 0.02% MMC. The mean pre-revision IOP was 6.38 ± 2.80 and 6.51 ± 2.78 mmHg in the paediatric and adult group respectively, p = 0.86. At 3 months post-revision, it increased to 11.81 ± 3.48 and 12.75 ± 3.52 mmHg respectively (p < 0.001). At final review, mean IOP of paediatric group was 10.90 ± 2.59 and adult group was 11.86 ± 2.66 mmHg, p = 0.20. At 5 years, complete success was 68.18% and 72.41%, and qualified success was 31.87% and 27.59% in the former and latter group respectively, p = 0.49. No failures were seen. Kaplan-Meier probability at 5 years for IOP target ≤ 18, ≤ 15 and ≤ 12 in children was 95.45%, 63.64% and 50% and in adults 93.10%, 65.52% and 41.38% respectively. BCVA improved up to 1 year in paediatric group, with continued improvement in adults up to 3 years. SSOCT measured bleb height was 0.88 ± 0.37 and 1.32 ± 0.49mm in children versus adults (p = 0.006) and wall thickness, 0.35 ± 0.22 and 0.58 ± 0.24mm respectively, p = 0.008. CONCLUSION: Bleb-sparing epithelial exchange is an equally safe and effective technique with good long-term success in both paediatric and adult dysfunctional blebs.

Evaluation of the Role of Umbilical Cord Serum and Autologous Serum Therapy in Reepithelialization After Keratoplasty: A Randomized Controlled Clinical Trial.

PURPOSE: To evaluate the role of umbilical cord serum (UCS) and autologous serum (AS) therapy in reepithelialization of corneal graft after keratoplasty in a randomized controlled trial. METHODS: A total of 105 eyes with epithelial defect (ED) after keratoplasty (penetrating keratoplasty-67 and anterior lamellar keratoplasty-38) on the first postoperative day were included in the study. The eyes were randomized into three groups: UCS (n=35), AS (n=35), and artificial tears (AT) (n=35). All patients received standard postoperative medical therapy. The primary outcome measure was time to epithelialization, and secondary outcome measures were best-corrected visual acuity and graft clarity. RESULTS: The ED healed completely in 103 eyes. The mean time for complete reepithelialization was 2.5±2.1, 3.1±2.2, and 4.5±1.4 days in UCS, AS, and AT groups, respectively. The mean percentage decrease in the size of the ED was significantly better in the UCS and AS groups as compared with the AT group (P=0.001). The rate of reepithelialization was comparable between the AS and UCS groups (P=0.3). On bivariate analysis, significant correlation was found between the mean size of postoperative ED, grade of the donor cornea (P=0.001), and the presence of preoperative ED (P=0.001). No complications were associated with the use of serum therapy. CONCLUSION: Most of the cases of postkeratoplasty corneal ED can be managed with AT only. The serum therapy (AS/UCS) helps in the faster reepithelialization of postkeratoplasty ED as compared with AT and may be considered as a treatment option for early epithelial healing.

Intracranial hypotension with subdural hematoma after spinal anesthesia in obstetric patient: A rare but fatal complication.

Intracranial bleed in the form of subdural hematoma (SDH) with intracranial hypotension after spinal anesthesia for cesarean section is a rare condition with an incidence of around 1 in 5,00,000 obstetric populations. As its presentation is similar to post-dural puncture headache (PDPH), it can be misdiagnosed sometimes. Persistent headache for more than 5 days, vomiting, blurring of vision, and convulsion can guide the diagnosis of intracranial bleed. Magnetic resonance imaging (MRI) helps to diagnose the location, size, and other abnormalities of bleed in such patients. The management ranges from conservative to surgical management in the form of craniotomy. Here, we present a case of a 19-year-old woman, who operated on for cesarean section under spinal anesthesia presented with SDH and intracranial hypotension on postoperative day (POD) 6. She was managed conservatively with plenty of intravenous (IV) fluids, bed rest, low head position, analgesics, and antiepileptics. A repeat computed tomography (CT) scan was performed after 14 days, which showed resolved SDH, and the patient was discharged.

Circumpapillary optical coherence tomography angiography differences in perimetrically affected and unaffected hemispheres in primary open-angle glaucoma and the preperimetric fellow eye.

Purpose: Evaluation of circumpapillary vessel density (VD) and perfusion density (PD) on optical coherence tomography angiography (OCTa) in mild-moderate glaucoma patients having unilateral visual field defects, with their fellow eyes and controls. Methods: Both eyes of 24 patients having a definitive nasal step or arcuate scotoma in one hemisphere of one eye only, and 24 controls, underwent OCTa. Results: In eyes with a superior field defect, the superior/inferior quadrant ratios, (SQ/IQ) of 3 mm scan of VD and PD were significantly higher in eyes with a superior arcuate scotoma than fellow eyes (P = 0.03,0.02) as also controls, (P = 0.004,0.001). The mean percentage loss of inferior quadrant VD between control to fellow eyes, and superior nasal step eyes were similar, 20.19%/19.57% respectively, P = 0.85, while a loss in arcuate scotoma eyes was 38.81% (P = 0.001). The percentage decrease in inferior quadrant PD in fellow eyes was 14.70%, superior nasal step 23.39%, and an arcuate scotoma 34.74% (P = 0.02). Eyes with a superior nasal step had significantly lower VD and PD absolute values in the inferior quadrant OCTa in 3 mm and 6 mm circle scan only as compared to control eyes, VD, P = 0.03,0.04/PD, P = 0.008,0.02. Fellow eyes of superior field defects had significantly lower VD and PD absolute values in the inferior quadrant in 3 mm and 6 mm circle scan as compared to control eyes, VD, P = 0.006,0.04/PD, P = 0.01,0.03. Eyes with an isolated inferior field defect in only one eye, showed a significant decrease in both VD and PD in all quadrants as compared to fellow eyes and control eyes. A significant positive correlation was found between VD and RNFL thickness in peripapillary superior unaffected quadrants in eyes with superior field defects and inferior unaffected quadrants in inferior defects (P = 0.001 and 0.01). Conclusion: There was a statistically significant increasing SQ/IQ ratio and percentage loss of vascular parameters from control to fellow eyes, those with a superior nasal step, and those with a superior arcuate scotoma. Inferior VFDs appeared to be associated with a more generalized circulatory loss. The asymmetry between hemispheres and between eyes could be used as a biomarker for early glaucomatous neuropathy.

Comparison of an aspheric monofocal intraocular lens with the new generation monofocal lens using defocus curve.

PURPOSE: The aim of this study was to compare the visual outcomes of two monofocal intraocular lenses (IOLs), with emphasis on the defocus curve. METHODS: A total of 116 consecutive eyes with cataract, undergoing phacoemulsification with IOL implantation were included in the observational case series, and divided into two groups. 71 eyes were implanted with Tecnis Eyhance and 45 with Tecnis 1 monofocal IOL. Eyes with ocular comorbidities, previous ocular surgeries and corneal astigmatism >1 Diopters (D) were excluded from the study. Complete ophthalmic evaluation including uncorrected distance visual acuity (UDVA), corrected distance visual acuity (CDVA), uncorrected intermediate visual acuity (UIVA), corrected intermediate visual acuity (CIVA), uncorrected visual acuity (UNVA), corrected near visual acuity (CNVA) was noted and defocus levels ranging from -4.00 D to + 1.00 D were plotted postoperatively in both groups. RESULTS: Uncorrected intermediate visual acuity (UIVA) and uncorrected near visual acuity (UNVA) was significantly better in Tecnis Eyhance group compared to Tecnis 1 monofocal. Both the IOLs have similar performance for distance vision but visual acuity at intermediate and near is significantly better with Tecnis Eyhance compared to Tecnis 1 piece IOL. CONCLUSION: Tecnis Eyhance IOL with its better defocus curve, not only provides good distance, but intermediate vision as well. With significantly better visual acuity across the range of near and intermediate vision, Tecnis Eyhance IOL can prove to be a viable and reasonable option for patients who are more dependent on intermediate vision in daily activities.

Uncontrolled neovascular glaucoma - an alarming manifestation of chronic myeloid leukemia on imatinib therapy - a case report and review of literature.

A 45-year-old diabetic male, with diabetic retinopathy and medically uncontrolled neovascular glaucoma (NVG) underwent intracameral bevacizumab followed by trabeculectomy, with controlled intraocular pressures (IOP) post-operatively, OD: 12 mmHg; OS: 14 mmHg. Patient was referred to hematology, where he was diagnosed as chronic myeloid leukemia (CML) and started on imatinib mesylate. Thereafter, he presented with recurrence of neovascularization and vascularization of the bleb along with OS vitreous hemorrhage at 6 weeks follow-up. While he was planned for OS vitreo-retinal surgery, he presented with OD spontaneous hyphema with raised IOP (OD: 38 mmHg, OS: 16 mmHg). He had maintained a tight glycemic control. Following imatinib therapy, there was a rapid progression and recurrence of neovascularization, eventually leading to failure of trabeculectomy OD and bilateral severe loss of vision. Imatinib may be implicated in the worsening of NVG in CML patients, especially with co-existing diabetes and thus, such patients should receive regular thorough ophthalmic evaluation as long as imatinib continues.

'Van Herick Plus': a modified grading scheme for the assessment of peripheral anterior chamber depth and angle.

AIM: To evaluate the accuracy of a new, modified grading scheme involving a short vertical slit beam, at the inferior angle for peripheral anterior chamber depth (PAC) and angle estimation and its correlation with anterior segment optical coherence tomography (ASOCT). METHODS: A cross-sectional study of consecutive phakic patients, above 40 years of age, was performed. Using a short, vertical slit beam not reaching the pupil, the inferior angle at the sclerolimbal junction was evaluated, photographed and assessed by a ratio of peripheral anterior chamber depth to peripheral corneal thickness (PAC:PCT) and iridocorneal angle (ICA) on ImageJ software. The inferior angle at the same meridian was also recorded on ASOCT. RESULTS: Based on the PAC:PCT ratio, the subjects were divided into four groups: I (<1/4), II (1/4-1/2), III (>1/2-1) and IV (>1). The clinically assessed angle by short vertical slit beam correlated well with ASOCT values, trabecular-iris angle (TIA) (r=0.918; p<0.001) and scleral spur angle (r=0.903, p<0.001). The mean difference between ICA and TIA on ASOCT was 0.7970; 95% limits of agreement:-5.7670 to 7.3610 (±1.96 SD). For angles graded narrow on ASOCT (TIA <200), using a cut-off of peripheral PAC:PCT <1/4, the area under the curve was 0.918 with a sensitivity of 85.2% and a specificity of 88.2%. There was good agreement between ImageJ parameters with those assessed subjectively on photograph of the slit beam examination by a glaucoma fellow (weighted kappa=0.74) as compared with a general ophthalmologist, where there was moderate agreement (weighted kappa=0.57). CONCLUSION: A short, vertical slit lamp beam evaluation at the inferior angle is an easy and relatively accurate method for both peripheral anterior chamber depth and angle assessment. It correlated well with ASOCT and can be used as a more reliable screening tool to identify eyes with possibly occludable angles.

Comparison of Epidural Analgesia Using 0.2% Bupivacaine and 0.2% Ropivacaine for the Management of Postoperative Pain in Major Orthopedic Surgery.

INTRODUCTION: Ropivacaine is preferred over racemic bupivacaine for postoperative analgesia as it is less cardiotoxic and has high selectivity for sensory fibers. We aim to compare postoperative epidural analgesia using 0.2% bupivacaine and 0.2% ropivacaine in major lower limb orthopedic surgery. MATERIALS AND METHODS: In a prospective, randomized, double-blind study, 100 patients, aged 18-70 years, undergoing elective major lower limb orthopedic surgery under spinal anesthesia, were randomly allocated to receive either 7 ml ropivacaine 0.2% (Group R) or 7 ml bupivacaine 0.2% (Group B) for postoperative analgesia through a lumbar epidural catheter. The onset and duration of epidural analgesia, total epidural dose requirement, mean number of epidural topup, rescue analgesia, incidence of motor blockade, and adverse effects were recorded. RESULTS: No differences were noted in demographic data and hemodynamic variables in either group. The onset time of epidural analgesia was 10.46 min ± 0.68 (Group B) and 10.52 min ± 0.71 (Group R). The duration of analgesia was 253.10 ± 17.46 min (Group B) and 251.80 ± 15.77 min (Group R). The total analgesic dose requirement was 78.40 mg ± 6.93 in Group B while in Group R, it was 78.96 mg ± 6.79. Epidural topup requirement and the need for rescue analgesia were similar in both the groups. Motor blockade, hypotension, and nausea were noted more in Group B compared to Group R. CONCLUSION: In patients undergoing major lower limb orthopedic surgery under subarachnoid block, epidural ropivacaine 0.2% produces effective postoperative analgesia similar to bupivacaine 0.2% with a distinct sensory-motor dissociation resulting in analgesia without motor blockade.

Retinal Nerve Fiber Layer Changes Following Primary Retinal Detachment Repair with Silicone Oil Tamponade and Subsequent Oil Removal.

PURPOSE: To evaluate the correlation between the retinal nerve fiber layer (RNFL), particularly the temporal RNFL (TRNFL), and visual outcomes following surgery for rhegmatogenous retinal detachment (RRD). METHODS: This retrospective study was performed at a tertiary center; 32 patients underwent single and successful vitrectomy for total RRD using silicone oil as tamponade. Data were collected after oil removal. RNFL thickness and central foveal thickness (CFT) were measured using spectral domain optical coherence tomography. RNFL thickness and CFT of normal eyes were acquired as a control to calculate percentage changes in the affected eyes. The correlation between postoperative best-corrected visual acuity (BCVA) and TRNFL changes was the primary outcome measure. RESULTS: Postoperative BCVA correlated negatively with retinal detachment (RD) duration (Pearson coefficient 0.56, P = 0.001) and percentage loss in TRNFL thickness (Pearson Coefficient 0.41, P = 0.02). The macula lost the maximum RNFL thickness (26%). The mean percentage loss of TRNFL was significantly higher in patients with postoperative BCVA <6/60 (42.63% vs. 24.06%, P = 0.009). Patients with postoperative BCVA <6/60 had a significantly longer mean RD duration (29 days) than those with postoperative BCVA >6/60 (17.5 days) (P = 0.026). CONCLUSION: When eyes with RRD are successfully repaired using silicone oil tamponade, the thickness of the RNFL decreases, particularly in the macula, and less macular neuronal loss is associated with better visual outcomes.
