ABSTRACT: To determine the normative values of the peripapillary retinal nerve fiber layer (RNFL), macular thickness, and macular volume in healthy children using spectral-domain optical coherence tomography (SD-OCT) and analyze the correlation of such values with age, refraction error, and biometric measurements.
Observational case series.
This institutional study involved 107 eyes from 107 healthy pediatric patients (54 female, 53 male) with ages between 6 and 16 years. After the biometric measurements and refractive error values (in spherical equivalent) of the cases were obtained, the peripapillary RNFL, macular thickness, and macular volume values were calculated using the Spectralis OCT device.
Among the study group, with an average age of 10.46 ± 2.94 years, the average axial length (AL) was 23.33 ± 0.89 mm; the average spherical equivalent (SE) value was -0.27 ± 0.99 diopter. The average peripapillary RNFL thickness was 106.45 ± 9.41 μm; the average macular thickness was 326.44 ± 14.17 μm; and the average macular volume was 0.257 ± 0.011 mm(3). The aforementioned OCT measurements were not significantly correlated with age, SE, or AL values (P > .05 for all).
This study reports SD-OCT findings among healthy pediatric cases. SD-OCT can be reliably used for pediatric patients because of its short exposure time and high degree of image resolution.

ABSTRACT: The response to combined laser photocoagulation and a single intravitreal injection of 0.75 mg bevacizumab to each eye on separate days in two patients with aggressive, posterior retinopathy of prematurity (ROP) is described. Combined treatment resulted in regression of zone-1 disease in Case 1, which had no retinal detachment. However, no significant regression or unfavorable anatomic response was observed in the second case with retinal detachment. Although the combination of laser photocoagulation and intravitreal bevacizumab injection seems to be well tolerated, inducing prompt regression of agressive zone-1 ROP without retinal detachment, further controlled studies with long-term follow-up are necessary for their use in the treatment of ROP with for potentially dangerous growth factor inhibitors in premature babies.

ABSTRACT: To determine the frequency of ophthalmologic problems and the risk factors that affect the occurrence of these problems in premature newborns with a gestational age of 32 weeks or less.
Premature newborns observed at a neonatal intensive care unit between January 2002 and March 2006 were included. A control visit including an ophthalmologic examination was performed at 10 months of age or later. Primary ocular morbidities were studied, and the association between these parameters and prenatal, perinatal, and neonatal characteristics were evaluated.
A total of 169 premature newborns were included in the study, and they were examined at a mean age of 25.85 ± 11.79 months (range: 10 to 42 months). There was complete vision loss (blindness) in 1 (0.6%) case, strabismus in 15 (8.9%) cases, and refractive errors in 10 (5.9%) cases. Twenty (77%) cases with any abnormality and 50 (35%) cases with a normal examination at follow-up had a history of retinopathy of prematurity (ROP) at any stage during the neonatal period (P = .001). Short gestational age (P = .018), low birth weight (P = .002), and the presence of ROP requiring retinal surgery during the neonatal period (P = .007) were determined to be significant risk factors for the development of vision loss, strabismus, and refractive errors.
Neonates with a gestational age of 32 weeks or less, especially those younger than 30 weeks, should not only be screened for ROP in the neonatal period, but should also have regular follow-up examinations to check for the development of other ophthalmologic problems during infancy and early childhood.

ABSTRACT: Congenital absence or hypoplasia of some or all major salivary or lacrimal glands, nasolacrimal ducts, and puncta is a rare autosomal dominant disorder. Phenotypical expression may show great variability, and the diagnosis may be difficult. Only a few cases have been reported in the literature. This report describes a patient who has all of the essential features suggestive of aplasia of the lacrimal and salivary glands, as well as retardation of growth and development. Although the characteristic features of aplasia of the lacrimal and salivary glands have been described, an association with development and growth retardation has not been reported in the literature.

ABSTRACT: To investigate binocularity in Duane's retraction syndrome (DRS) and to evaluate whether or not there is a relationship between the sensory and clinical features of the syndrome.
Clinical and sensory findings of 29 patients with DRS were recorded. Binocularity was tested with the Bagolini glasses (BG), Worth four-dot (W4D), TNO and the stereo-fly plate of the Titmus test.
Twenty-four (83%) patients showed fusion with the BG at near and 23 (79%) had fusion at distance. With the W4D, 23 (79%) patients had fusion at near and 19 (65%) had fusion at distance. Seven (24%) patients demonstrated normal stereoacuity, 15 (52%) had reduced stereoacuity and the remaining seven (24%) patients had no measurable stereoacuity. In patients without stereoacuity, amblyopia (p < 0.001), type 2 and 3 DRS (p = 0.031) and exotropia (p = 0.003) in primary position were more common than in those with reduced or with normal stereoacuity. Restriction of ocular ductions was also more severe in patients without stereoacuity than in those with reduced or normal stereoacuity (p = 0.019, p = 0.016). Patients with type 2 and 3 DRS were significantly more likely to have amblyopia (p = 0.037), large-angle heterotropia (p = 0.005) in primary position, upshoot or downshoot (p = 0.010) than those with type 1 DRS.
Although approximately 75% of DRS patients had fusion and measurable stereoacuity, only 25% demonstrated normal binocularity. This report provides new data on the relationship of sensory features to most of the clinical findings of this syndrome. Sensory features, as well as most clinical features of the syndrome, are better in patients with type 1 DRS.

ABSTRACT: Purpose: Investigation of the causes and risk factors of amblyopia which is the most important cause of legal blindness with a prevalance of 2,5% among people under 45 years old in developed countries. Material and Methods: A screening test was performed to 3-6 years old preschool children and kindergartens in Ankara. The records included age, sex, birth problems, education level of the parents, pre and postnatal problems, family history and visual acuities. Suspected cases were sent to the ophthalmologist for the examination of visual acuity, and duction and version, biomicroscopic, ophthalmoscopic and cycloplegic refractive examinations. Visual acuity of 8/10 or less without any organic cause was accepted as amblyopia. Results: Fifty six of the 202 children were sent to the ophthalmologist because of low vision. Ophthalmologic examination revealed 6 amblyopia cases. The prevalance of amblyopia was 2,97%. Conclusion: Ambliyopia was 3 times more frequent in cases with a positive family history compared with cases without a family history. But this value was statistically insignificant. The most frequent causes of amblyopia were esotropia (50%), hypermetropic amblyopia (33,3%), and deprivation amblyopia (16,6%).

ABSTRACT: To report the management outcomes of diplopia in patients with blowout fracture.
Data for 39 patients with diplopia due to orbital blowout fracture were analyzed retrospectively. The inferior wall alone was involved in 22 (56.4%) patients, medial wall alone was involved in 14 (35.8%) patients, and the medial and inferior walls were involved in three (7.6%) patients. Each fracture was reconstructed with a Medpore® implant. Strabismus surgery or prism correction was performed in required patients for the management of persistent diplopia. Mean postoperative follow up was 6.5 months.
Twenty-three (58.9%) patients with diplopia underwent surgical repair of blowout fracture. Diplopia was eliminated in 17 (73.9%) patients following orbital wall surgery. Of the 23 patients, three (7.6%) patients required prism glasses and another three (7.6%) patients required strabismus surgery for persistent diplopia. In four (10.2%) patients, strabismus surgery was performed without fracture repair. Twelve patients (30.7%) with negative forced duction test results were followed up without surgery.
In our study, diplopia resolved in 30.7% of patients without surgery and 69.2% of patients with diplopia required surgical intervention. Primary gaze diplopia was eliminated in 73.9% of patients through orbital wall repair. The most frequently employed secondary surgery was adjustable inferior rectus recession and <17.8% of patients required additional strabismus surgery.
