The outcomes of 326 external dacryocystorhinostomy operations in children with dacryostenosis - 30-year experience of an oculoplastic surgeon

ABSTRACT Purpose: To report demographic features and surgical outcomes of 320 children undergoing external dacryocystorhinostomy for dacryostenosis. Methods: We performed a retrospective evaluation of the records of patients aged <16 years who underwent external dacryocystorhinostomy. Patient demographic features and success rates of the operations were analyzed from the data records. Children with <12-month follow-up were not enrolled in the study. Results: We identified 326 operative records of 320 children (162 [50.6%] girls and 158 [49.4%] boys) who underwent external dacryocystorhinostomy with a mean follow-up of 26.03 ± 11.11 months. Overall, we evaluated 116 (35.6%) cases of congenital nasolacrimal duct obstruction. Our series demonstrated a 99.4% success rate for external dacryocystorhinostomy. Conclusions: External dacryocystorhinostomy in children has a high success rate if performed by an experienced oculoplastic surgeon

Retinal choroidal and retinal nerve fiber layer thickness in former preterm and full-term infants aged 4 to 8 years

Purpose To compare the retinal thickness at the fovea center, peripapillary retinal nerve fiber layer (RNFL) thickness and choroidal thickness (CT) in former preterm and full-term infants. Methods A total of 121 healthy children aged 4-8 years were divided 4 groups: group 1; children born on time, group 2; preterm children without a history of retinopathy of prematurity (ROP), group 3; preterm children with a history of spontaneously regressed ROP and group 4; preterm children who underwent diode laser photocoagulation for ROP. The retinal thickness at the fovea, peripapillary RNFL thickness at global, superior, inferior, nasal and temporal quadrants and submacular CT at 7 different points were measured by using spectral-domain optical coherence tomography. Results The mean retinal thickness at the fovea center was statistically higher, whereas the mean RNFL thickness values in global, nasal, superior and inferior quadrants were statistically lower in group 4. No difference was found in the mean submacular CT value of any point between the groups. Conclusion Transpupillary diode laser photocoagulation treatment for ROP seems to cause an increase in macular thickness and a decrease in RNFL thickness

Rehabilitation Methods for Patients with Geographic Atrophy due to Age-Related Macular Degeneration and Effects of Rehabilitation on Quality of Life

Purpose. The purpose of the study is to evaluate the low vision rehabilitation methods and to investigate the effect of visual rehabilitation on quality of life in patients with low vision due to geographic atrophy from age-related macular degeneration (ARMD).Methods. The better-seeing eye of 78 patients with geographic atrophy due to ARMD were included in the study. Sociodemographic characteristics, ophthalmological examination findings, and preferred low vision aids for near and distant were recorded. Fifty-seven patients who preferred to use a low vision aid device in daily life were considered as a rehabilitation group, whereas 21 patients who did not use any device were considered as a control group. The National Eye Institute Visual Function Questionnaire (NEI-VFQ-25) was applied to all patients at the initial examination and at least 6 months after the initial examination.Results. In the rehabilitation group, statistically significant increases were found in the overall composite score, and general vision, near and distance activities, social functioning, mental health, role difficulties, and dependency subscale scores of the NEI-VFQ-25 quality of life scale after low vision rehabilitation (p=0.009 for general vision, p0.05). All patients (n = 78) were recommended to use at least one low vision aid for near vision. Hyperocular glasses were recommended for 77 patients (98.72%), magnifiers for 15 patients (19.23%), electro-optical devices for 2 patients (2.56%), and telemicroscope for one patient (1.28%). Furthermore, 17 patients (21.8%) were prescribed more than one low vision aids. However, for distance vision, only 29 patients (37.18%) received a recommendation for a low vision aid.Conclusions. Low vision patients with ARMD-related geographic atrophy should meet with low vision aids as soon as possible and should be included in low vision rehabilitation programs

The relationship of birth weight, gestational age, and postmenstrual age with ocular biometry parameters in premature infants

Purpose: To analyze ocular biometry parameters and evaluate their relationship with gestational age, birth weight, and postmenstrual age in prematurely born infants. Methods: The right eyes of 361 premature infants born before the 36th gestational week were evaluated. Birth weight, gestational week, and gender were recorded. An A-scan Biometer was used for obtaining axial measurements, including anterior chamber depth, lens thickness, vitreous length, and total axial length. Results: Gestational age and birth weight values ranged from 23 to 36 weeks and from 560 to 2,670 g, respectively. The mean gestational age and birth weight were 30.8 +/- 2.8 weeks and 1,497.9 +/- 483.6 g, respectively. During the first examination (4-5 weeks of postnatal age), birth weight and gestational age of the infants correlated significantly and positively with lens thickness, vitreous length, and axial length (r>0.5, p<0.001), but not with anterior chamber depth (r<0.5). Increased vitreous and axial lengths correlated significantly with increasing postmenstrual age of the infants (r=0.669, p<0.001; r=0.845, p<0.001, respectively). Conclusions: Lens thickness, vitreous length, and axial length, but not anterior chamber depth, were significantly correlated with birth weight and gestational age. All four parameters increased with increasing postmenstrual age, with higher correlations for vitreous and axial lengths than for anterior chamber depth and lens thickness. It was concluded that axial elongation resulted primarily from increasing posterior chamber length.WoSScopu

Analysis of the Horizontal Corneal Diameter, Central Corneal Thickness, and Axial Length in Premature Infants

Purpose: To determine the horizontal corneal diameter, central corneal thickness, and axial length in premature infants. Methods: Infants with a birth weight of less than 2,500 g or with a gestation period of less than 36 weeks were included in the study. Infants with retinopathy of prematurity (ROP) were allocated to Group 1 (n= 138), while those without ROP were allocated to Group 2 (n= 236). All infants underwent a complete ophthalmologic examination, including corneal diameter measurements, pachymetry, biometry, and fundoscopy. Between-group comparisons of horizontal corneal diameter, central corneal thickness, and axial lengths were performed. Independent sample t-tests were used for statistical analysis. Results: Data was obtained from 374 eyes of 187 infants (102 female, 85 male). The mean gestational age at birth was 30.7 +/- 2.7 weeks (range 25-36 weeks), the mean birth weight was 1,514 +/- 533.3 g (range 750-1,970 g), and the mean postmenstrual age at examination was 40.0 +/- 4.8 weeks. The mean gestational age and the mean birth weight of Group 1 were statistically lower than Group 2 (p 0.05). Conclusions: The presence of ROP in premature infants does not alter the horizontal corneal diameter, central corneal thickness, or axial length.WoSScopu
