The objective of this study was to analyze the characteristics and surgical results of pediatric rhegmatogenous retinal detachment (RRD). The medical records of 30 eyes of 29 patients younger than 18 years of age who underwent vitreoretinal surgery due to RRD were analyzed. The gender, age, laterality, duration of presenting symptom, etiology, ocular and systemic co-morbidities, type of breaks, lens status, presence of proliferative vitreoretinopathy (PVR) and its grade, initial and final best-corrected visual acuities (BCVAs), surgical management, number of operations, duration of follow-up, functional and anatomical success, and complications were noted. As the most common predisposing factors were trauma (trauma group) and myopia (myopia group), the data of these patients were further analyzed. The mean age was 12.6 ± 3.0 years. There were 23 male (79.3 %) and 6 female (20.6 %) subjects. The most common etiologic factors were high myopia (40 %) and trauma (36.6 %). Functional success rate was 70 % (n = 21) after the primary surgeries and was 80 % (n = 24) after the secondary surgeries. There were no significant differences between the trauma and myopia groups regarding the presence of total retinal detachment, macula-off status, and the rate of PVR worse than grade C. Although the preoperative mean BCVA and the initial and final retinal reattachment rates of the groups were statistically similar, trauma group had significantly higher postoperative mean BCVA compared to myopia group (p = 0.013). Myopia and trauma were the most common etiologic factors for RRD in children. The visual outcomes of trauma-associated RRD were better than those of myopia-associated RRD.

We have shown that axial length/refractive status affected the peripapillary RNFL thickness profile measured by RTVue OCT. To make a correct diagnosis for glaucoma, either the axial length-induced magnification effect should corrected by ophthalmologists or the RTVue OCT database should be improved by taking axial length into account.

LE was as effective as prednisolone and more effective than fluorometholone, and it had no side effects during the short-term treatment of VKC patients.

Purpose. To investigate changes of dry eye test results in patients who underwent pterygium surgery. Methods. Seventy-four patients who underwent primary pterygium surgery were enrolled in this study. At the baseline, 3-, 12-, and 18-month visits, measurements of tear osmolarity, BUT, and Schirmer test were performed. The patients were divided into 2 groups: Group 1, which consisted of patients in whom pterygium did not recur, and Group 2, which consisted of patients in whom pterygium recurred after surgery. Results. The patients in Group 1 had lower tear osmolarity levels after surgery than those at baseline (all P < 0.001). In Group 2 the tear osmolarity levels did not differ from baseline after 18 months (P = 0.057). The prevalence rates of dry eye syndrome (DES) were lower than that at baseline and 18 months after surgery in Group 1 (P = 0.002). In Group 2, the incidence of DES was lower after 3 months than at baseline (P = 0.03) but was similar to the baseline rate after 12 and 18 months (both P > 0.05). Conclusions. Anormal tear film function associated with pterygium. Pterygium excision improved tear osmolarity and tear film function. However, tear osmolarity deteriorated again with the recurrence of pterygium.

Purpose To investigate the effects of tropicamide and cyclopentolate, which are two anti-muscarinic agents commonly used in the ophthalmologic practice, on subfoveal choroidal choroidal thickness (ChT) in healthy adults. Methods A total of 74 healthy adult subjects were enrolled in the study. Subjects were randomly divided into two groups: (1) cyclopentolate group (n = 37) in which the right eye (study eye) of each subject received topical cyclopentolate 1%, and the fellow eye (control eye) received artificial tears and (2) tropicamide group (n = 37) in which the right eye (study eye) of each subject received topical tropicamide 1% and the fellow eye (control eye) received artificial tears. Each topical medication was applied three times with 10-min intervals. ChT measurements were performed at baseline and 40 min after the last drops of the topical medications by enhanced depth imaging (EDI) optical coherence tomography (OCT). Results In the cyclopentolate group, subfoveal ChT significantly increased in the study eyes (P = 0.013), whereas it did not significantly change in the control eyes (P = 0.417). On the other hand, in the tropicamide group, no significant subfoveal ChT changes were observed in either the study eyes (P = 0.715) or the control eyes (P = 0.344). Conclusions The current study demonstrated that cyclopentolate caused significant choroidal thickening, whereas tropicamide had no significant effect on ChT in healthy adults. As a result, mydriasis by cyclopentolate may complicate ChT measurements by EDI OCT. Use of tropicamide may provide more reliable results for evaluation of ChT in ocular pathologies.

The NLR values were found to be higher in patients with non-Sjögren dry eye than in controls. This result suggests that non-Sjögren dry eye disease may be associated with systemic inflammation or the NLR values may increase in local inflammatory ocular diseases.

We have demonstrated that when measured using the Stratus OCT, which does not take magnification into account, measurements erroneously indicate that children with high hyperopia had thicker RNFLs in inferior and nasal quadrants than children with low hyperopia. The current Stratus OCT normative database may be misleading for correct diagnosis of glaucoma in highly hyperopic children.

In conclusion, axial length influences peripapillary RNFL thickness as measured by RTVue OCT. However, this appears to be due to the ocular magnification effects associated with axial length and can be corrected for with the application of the Littman formula.
