ABSTRACT
Background Every year, 3.3 to 5.7 million eye injuries occur worldwide in children. Open globe injury is a common type of trauma that leads to blindness in all age groups. This study aimed to review and discuss the epidemiology, causes, and clinical outcome of pediatric open globe injury. Methods A retrospective chart review of all pediatric open globe injuries presented to King Fahad Hospital of the University and Dhahran Eye Specialist Hospital was conducted between 2010 and 2020. Data analyses were done to identify factors predicting ultimate visual acuity. Results The overall number of cases was 502, of which 120 cases were children and of the documented 118 cases, around 82 (69.5%) were males with an average age of 5.1 years. The traumatic object was sharp in 90 (89.1%) cases. The most common object was glass, presented in 18 (18.4%) cases. Most injuries were accidental (68.9%) and 48 (71.6%) cases out of 67 occurred inside the house. The factors associated with better visual outcome (20/40 or better) were sharp injuries, absence of hyphema, absence of vitreous hemorrhage, trauma with intraocular foreign body, undergone one operation, and absence of cataract at presentation. Conclusion The ultimate visual outcome post open globe injury could be predicted from the severity of the presenting signs. Also, the household environment carries the highest risk, hence it is not always a safe haven for children. Thus, childproofing the house and adult supervision is advisable.
ABSTRACT
PURPOSE: To compare the treatment efficacy of optical correction and occlusion therapy and/or penalization for different anisometropic refractive errors (hyperopic, myopic, and mixed). METHODS: Medical records of 51 patients with anisometropic amblyopia managed by both optical correction and occlusion therapy and/or penalization were evaluated retrospectively. Patients were categorized into hyperopic, myopic or mixed anisometropia groups. Cycloplegic refraction, spherical anisometropia, baseline visual acuity, baseline interocular difference, final visual acuity and final interocular difference were analyzed to assess association between type of anisometropia with both resolution of anisometropic amblyopia and the time required to achieve it. RESULTS: Baseline visual acuity of the amblyopic was 0.94±0.47 in the hyperopic group; 1.12±0.56, in the myopic group; and 1.08 ±0.39 in the mixed group. Final visual acuity in the amblyopic eye was 0.34±0.30 in the hyperopic group, 0.78±0.59 in the myopic group, and 0.78±0.56 in the mixed group. The difference in final visual acuity in the amblyopic eye between the groups was significant (P=0.014). The amblyopia was improved in 50% of patients in the hyperopic group, 23.8% in the myopic group, and 14.3% in the mixed group (P=0.081). The type of anisometropia was significantly associated with the improvement of visual acuity in the amblyopic eyes (P=0.044). The mean time for amblyopia improvement was 16.50±10.52 months in the hyperopic groups, 15.60±12.44 months in the myopic group, and 21.00±21.21 months in the mixed group (P=0.947). CONCLUSION: Lower amounts of hyperopic anisometropia are as amblyogenic as higher amounts of myopic or mixed anisometropia. Mean improvement in visual acuity of an amblyopic eye with both optical correction, occlusion therapy and/or penalization is higher in patients with hyperopic anisometropia in comparison with myopic or mixed anisometropia. No significant difference was found in the time required to achieve improvement between the study groups.
ABSTRACT
PURPOSE: To compare intraocular pressure (IOP) measurements by rebound tonometry (Icare PRO; Icare Finland Oy, Helsinki, Finland) to measurements by indentation tonometry (Pneumotonometer Model 30 classic and Tono-Pen XL; Reichert, Buffalo, NY, USA) in supine sedated children with glaucoma. METHODS: Prospective comparative observational study of Saudi Arabian children with glaucoma undergoing chloral hydrate sedation for ophthalmic examination (February 2012 - February 2013). Nonglaucomatous eyes were included as controls. Eyes with corneal scars or prior corneal transplant or lamellar surgery were excluded. RESULTS: Fifty-two eyes (26 OD, 26 OS) of 28 children were included. Thirty-six eyes had glaucoma (32 primary congenital glaucoma, two Sturge-Weber related, and two aphakia related). Sixteen eyes did not have glaucoma (six with pediatric cataract, five normal eyes, two strabismic eyes, two eyes with simple megalocornea, and one eye had peripheral corneal laceration repair. In the glaucoma group, the mean IOP was 17.55 ± 5.97 mmHg (range, 8-31.5 mmHg) with the Icare PRO and 20 ± 6.4 mmHg (range, 8-35.5 mmHg) with the Pneumotonometer from 20.47 ± 6.81 mmHg (range, 10-43 mmHg) with the Tono-Pen XL. The Icare PRO readings were significantly lower than each of the indentation tonometers. For the control group, there was no statistically significant difference in IOP measured by the Icare PRO and the indentation tonometers. CONCLUSIONS: In this population of supine sedated children with glaucoma, IOP measurements with the Icare PRO tend to be lower than readings from the Pneumotonometer and Tono-Pen XL.
