Abstract Backgroud: To evaluate the subfoveal choroidal thickness (SFCT) in eyes with macular edema secondary to retinal vein occlusion（RVO），and to investigate the short-term response after a single intravitreal Ranibizumab injection. What is more, to compare the SFCT and SFCT change in eyes with central RVO (CRVO) and branch RVO (BRVO). Methods: The observational case series had collected treatment-naïve patients with unilateral macular edema secondary to RVO retrospectively (19 CRVO and 17 BRVO). They had received at least one intravitreal ranibizumab (IVR) injection after newly diagnosed. The SFCT values before IVR and after 2 weeks of IVR were collected and analyzed. Paired t test was performed to compare the difference between RVO eye and its unaffected fellow eye, and to compare the SFCT change between before IVR and after 2 weeks of IVR. In further, the SFCT and SFCT change in eyes with CRVO and BRVO were also evaluated with independent t test. Results: Mean SFCT in CRVO eyes at the onset was 326.03±30.86 μm, which was significantly greater than that in contralateral fellow eyes (p<0.01, paired t test), and decreased to 294.15±30.83 μm rapidly after 2 weeks of IVR (p<0.01, paired t test). Similarly, the SFCT in BRVO eyes was significant thicker than its contralateral eyes at the onset, and reduced after IVR. However, our findings showed that there was no significant difference on the SFCT at the onset and SFCT change after IVR between CRVO eyes and BRVO eyes. Conclusions: The SFCT in eyes with macular edema secondary to RVO (CRVO or BRVO,respectively) was significantly greater than that in fellow eyes, and decreased significantly within a short time in response to a single IVR injection. It indicated choroid was involved in the progress of macular edema secondary to RVO. Our study collected recent-onset and treatment- naïve patients, it may help to elucidate the conflicting results of SFCT in RVO eyes reported by previous studies. In further, the study first showed that the SFCT may have no relationship with RVO subtypes. However, further study is need to investigate the exact relationship between SFCT and RVO subtypes.

Abstract Backgroud: To evaluate the subfoveal choroidal thickness (SFCT) in eyes with macular edema (ME) secondary to retinal vein occlusion（RVO），and to investigate the short term response after a single intravitreal ranibizumab (IVR) injection. What is more, to compare SFCT and SFCT change between central RVO (CRVO) and branch RVO (BRVO). Methods: In the retrospective study, we had collected thirty-six treatment-naïve patients with unilateral ME secondary to RVO (including nineteen CRVO and seventeen BRVO). All patients had received IVR injection after newly diagnosed. The SFCT was measured at the onset and after two weeks of IVR injection. Paired t test was performed to compare the SFCT of RVO eyes and fellow eyes, as well as the SFCT of pre-injection and post-injection. In further, independent t test was used to compare SFCT and SFCT change between CRVO eyes and BRVO eyes. Results: The mean SFCT at the onset was 326.03±30.86 μm in CRVO eyes, which was significantly thicker than that in contralateral fellow eyes (p<0.01, paired t test), and reduced to 294.15±30.83 μm rapidly after two weeks of IVR injection (p<0.01, paired t test). Similarly, the SFCT in BRVO eyes was significantly thicker than that in contralateral eyes at the onset, and decreased significantly after IVR injection. However, our findings showed that there was no statistically significant difference in SFCT and SFCT reduction after IVR injection between CRVO eyes and BRVO eyes. Conclusions: The SFCT in eyes with ME secondary to CRVO and BRVO was significantly thicker than that in fellow eyes, and decreased significantly within a short time in response to a single IVR injection. In further, the study showed that SFCT and SFCT change had no correlation with RVO subtypes.

Purpose:  To compare the short-term efficacy and safety of intraocular Ranibizumab and Bevacizumab in patients with treatment Naïve macular edema. Study Design:  Quasi experimental study. Place and Duration of Study:  Amanat Eye Hospital, from August 2018 to November 2019. Methods:  Patients with macular edema confirmed with optical coherence tomography (OCT) or leakage on fluorescein angiography were included. Patients with NVE, PDR without macular edema and patients who switched to alternative anti-VEGF compounds prior to the completion of three consecutive monthly injections of their respective anti-VEGF or switched to other treatment options were excluded from the study. A thorough clinical examination was conducted including best corrected visual acuity (BCVA, intraocular pressure (IOP), anterior and posterior segment examination and OCT macula. The patients were then allocated to one of the two study arms (either Bevacizumab or Ranibizumab) based on the doctor’s input and patient affordability. All patients underwent three consecutive injections of the selected molecule at one month intervals. BCVA, CRT and macular volume were then recorded 04 weeks after the third injection. Results:  A statistically significant mean vision gain was observed from baseline in both groups (p < 0.05). However, the change in BCVA was not significantly different between intravitreal Bevacizumab group and intravitreal Ranibizumab group (p > 0.05). Similarly, although there was improvement in CRT and macular volume in both groups but there was no statistically significant difference between the two. Conclusions:  Treatment with intravitreal Bevacizumab and Ranibizumab injections cause statistically similar anatomical and functional results in cases of treatment naïve macular edema.

Objective: To investigate the choroidal thickness in children with amblyopia through spectral-domain optical coherence tomography. Methods: A total of 31 children with unilateral amblyopia and 31 right eyes of controls with normal vision were enrolled in the study. The choroidal thickness was measured directly below the fovea and at 12 other locations: 1, 2 and 3 mm superior, temporal, inferior, and nasal to the fovea. All the parameters were compared between amblyopic eyes, fellow eyes, and control eyes. Results: The mean subfoveal choroidal thickness was 398.03 ± 74.60, 354.13 ± 81.78, and 328.12 ± 65.93 μm in amblyopic eyes, fellow eyes, and control eyes, respectively. Significant difference was found in choroidal thickness among three groups at subfoveal choroidal thickness, N1, and S1 using multivariate analysis of covariance after adjusting for axial length. Significant negative correlation was found only between subfoveal choroidal thickness and axial length in amblyopic eyes (r = –0.463, p = 0.01). Conclusion: The subfoveal choroid is significantly thicker in amblyopic eyes than control eyes only at subfoveal choroidal thickness, N1, and S1. The choroidal thickness was thickest in the subfoveal region and thinnest in the nasal region. There are other changes in choroidal structure associated with amblyopia.

Abstract Introduction Thalassemia, as the most common chronic hereditary blood disorder in humans, can impose many adverse effects on parents and their affected children. On the other hand, positive thinking is the method or the result of a positive focus on a constructive issue, so by teaching positive thinking, we can improve physical and social function, and promote emotional health and overall quality of life. The aim of this study was to determine the effect of positive thinking training on the quality of life of parents of adolescents with thalassemia. Methods This quasi-experimental study was performed on 52 parents of adolescents with thalassemia who attended Taleghani Hospital in Golestan province, Iran in 2017. Samples were randomly assigned into two groups of intervention and control. The positive thinking training (based on the theory of Martin Seligman) was carried out in the intervention group in 10 (45–60 min) sessions over a 5-week period. Data collection tools in this study were the World Health Organization (WHO) quality of life questionnaire (WHOQOL-BREF) and a demographic information questionnaire. Data were analyzed by SPSS-16 software using independent t-test, the paired t-test and a covariance test. Results The results of paired t-test showed a significant difference in the score of quality of life in intervention group before and after the intervention (p < 0.001). However, this test did not show any significant difference in the control group (p = 0.11). The covariance test, after removing the pre-test score, showed a significant difference between the intervention and control groups in terms of the score of quality of life, so that 13% of the changes after the intervention were due to the intervention (p = 0.009, η = 0.13). Conclusion The positive thinking training increased the quality of life of parents of adolescents with thalassemia. Therefore, using this program can be an effective way of improving the quality of life of parents. Thus, positive thinking training is suggested to be used as an effective strategy for increasing the quality of life of parents with ill children.

AbstractTo evaluate the effects of intravitreal ranibizumab injection (IVR) on metamorphopsia in patients with branch retinal vein occlusion (BRVO), and to assess the relationship between metamorphopsia and inner retinal microstructure and other factors. Thirty-three treatment-naïve eyes of 33 patients with macular edema caused by BRVO with at least 12 months of follow-up were included. The degree of metamorphopsia was quantified using the M-CHARTS. Retinal microstructure was assessed with spectral-domain optical coherence tomography. Disorganization of the retinal inner layers (DRIL) at the first month after resolution of the macular edema (early DRIL) and at 12 months after treatment (after DRIL) was studied. Central retinal thickness (CRT), and status of the external limiting membrane as well as ellipsoid zone were also evaluated. IVR treatment significantly improved best-corrected visual acuity (BCVA) and CRT, but the mean metamorphopsia score did not improve even after 12 months. Post-treatment metamorphopsia scores showed a significant correlation with pre-treatment metamorphopsia scores (P < 0.005), the extent of early DRIL (P < 0.05) and after DRIL (P < 0.05), and the number of injections (P < 0.05). Multivariate analysis revealed that the post-treatment mean metamorphopsia score was significantly correlated with the pre-treatment mean metamorphopsia score (P < 0.05). IVR treatment significantly improved BCVA and CRT, but not metamorphopsia. Post-treatment metamorphopsia scores were significantly associated with pre-treatment metamorphopsia scores, the extent of DRIL, and the number of injections. Prognostic factor of metamorphopsia was the degree of pre-treatment metamorphopsia.
