Invivo generated autologous plasmin enzyme assisted vitrectomy, partial circumferential-oral retinotomy, silicone oil injection in patients with chronic retinal detachment without posterior vitreous detachment.

PURPOSE: To report the results of invivo generated autologous plasmin enzyme(IVAP) assisted vitrectomy, partial circumferential-oral retinotomy and silicone oil injection for surgical treatment of patients with chronic retinal detachment without posterior vitreous detachment(PVD). METHODS: Study was performed in retrospective, comparative manner. A total of 16 consecutive eyes with chronic retinal detachment who had intravitreal injection of 50 µgr of t-PA and 0.1 ml of autologous whole blood, 3 days before surgery, underwent lens extraction with phacoemulsification, IVAP assisted vitrectomy, partial circumferential-oral retinotomy, and silicone oil injection(Study Group) were compared to a similar group of 15 eyes who had undergone vitrectomy, with or without lens extraction and silicone oil injection(Control Group) for the treatment of chronic retinal detachment. Primary outcome measures were initial retinal reattachment and number of operations at postoperative 6 months. RESULTS: Mean age of 16 patients of whom 7 were female, was 39.31 ± 17.76 years in study group and 15 patients of whom 4 were female, was 35.40 ± 11.92 years (p = 0.607). Mean follow-up time was 10.68 ± 7.15 months in study group and 29.13 ± 18.83 months in control group (p = 0.001). Initial retinal reattachment was achieved in 87.50% (14 out of 16 patients) in the study group, whereas it was 46.66% (7 out of 15 patients) in the control group (p = 0.017). The mean number of operations for reattachment in the study group was 1.12 ± 0.34, whereas it was 1.46 ± 0.51 in the control group (p = 0.039) at postoperative 6 months While the preoperative LogMAR visual acuity was 1.25 ± 0.64, it was 0.53 ± 0.37 at postoperative 6 months in study group (p = 0.001). Conversely, in the control group, the preoperative LogMAR visual acuity was 1.22 ± 0.33, it was 1.20 ± 0.89 at postoperative 6 months (p = 0.780). At postoperative 6 months,, epiretinal membrane developed in 2 eyes of the study group, 1 eye in the control group, and phthisis bulbi occurred in 1 eye of control group. CONCLUSION: IVAP assisted vitrectomy, partial circumferential-oral retinotomy and silicone oil injection is effective and safe for the surgical treatment of chronic retinal detachment without PVD.

The Effect of Robotic Rehabilitation on Hand Functions and Quality of Life in Children with Cerebral Palsy: A Prospective Randomized Controlled Study.

OBJECTIVE: This study aimed to examine the impact of robotic hand rehabilitation on hand function and quality of life in children with cerebral palsy. DESIGN: Children with cerebral palsy aged 7-16 years were divided into robotic rehabilitation (n = 9) or conventional rehabilitation (n = 10) groups for hand rehabilitation of 30 sessions. The primary outcomes were the Fugl-Meyer Assessment for Upper Extremity, and Box and Block Test. The secondary outcomes were the Manual Ability Classification System, Modified Ashworth Scale, hand grasp and finger strengths, ABILHAND-Kids, Functional Independence Measure for Children, and PedsQL Quality of Life Inventory-CP Module. RESULTS: In the robotic rehabilitation group, a significant improvement was found in all parameters after treatment (p < 0.05), except for the Functional Independence Measure (p = 0.081). In the conventional rehabilitation group, there was significant improvement after treatment in the Modified Ashworth Scale, Fugl-Meyer Assessment for Upper Extremity, hand grasp strength, Box and Block Test, ABILHAND-Kids, and PedsQL Quality of Life Inventory-CP Module (p < 0.05). Before and after treatment, all outcome parameters in the groups were similar (p > 0.05). CONCLUSIONS: Robotic hand rehabilitation is effective in improving motor function, manual dexterity, spasticity and quality of life in children with cerebral palsy. However, it was not demonstrated to be superior to conventional rehabilitation.

Evaluation of finger strength and spasticity in hemiplegic patients using hand-finger robotic device: A validity and reliability study.

We aimed to investigate the validity, reliability, and clinical relevance of Amadeo hand-finger robotic rehabilitation system measurements for evaluating spasticity and strength in hemiplegic patients. In total, 161 participants (107 hemiplegic patients and 54 sex- and age-matched healthy controls) were included in this study. Spasticity was evaluated using the Modified Ashworth Scale, hand motor functions were evaluated using the Fugl-Meyer Assessment Hand Subscale, and hand grip and pinch strength were evaluated using the Jamar hand grip and pinch dynamometer. The Amadeo (Tyromotion) hand-finger robotic rehabilitation system was used to evaluate finger spasticity and strength of the participants. A statistically significant difference was found between the median values of the Modified Ashworth Scale (both clinical and robotic evaluation results) and the mean values of hand flexor and extensor strength measured with the robotic device in patients compared to healthy subjects (P < .01). Statistically, excellent agreement was obtained between the clinical and robotic test-retest results of the scale (P < .01) (intra-class correlation coefficient, ICC = .98-.99; ICC = .98-.99, respectively). There was a statistically significant positive correlation between the clinical and robotic device results of the Modified Ashworth Scale (r = .72; P < .01). There was a statistically significant positive correlation between the hand strength values measured with the robotic device, Jamar grip, pinch, and Fugl-Meyer Assessment Hand Subscale scores (P < .01) in the patient group. Hand finger spasticity and strength measurements of the Amadeo hand-finger robotic rehabilitation system were valid, reliable, and clinically correlated in stroke patients.

Based on the Real-Life Data of Türkiye; Comparison of Anatomical and Functional Outcomes of Phakic and Pseudophakic Patients in Wet Type Age-Related Macular Degeneration.

Objectives: The aim of the study was comparison of wet-type age-related macular degeneration in phakic and pseudophakic patients in terms of anatomical and functional success based on the real-life data of Türkiye. Methods: The multicenter retrospective real-life study data of the. retinal study group were used in this study. Among 867 eyes of 867 patients were included in the study. Patients were divided into two groups according to the status of the lens; phakic group and pseudophakic group. The follow-up period of the two groups, the number of injections at the 1st, 2nd, and 3rd years, and changes in the central macular thickness (CMT, µ) and visual acuity (VA, logMAR) of the patients at the beginning, 6th, 12th, 24th, and 36th months were examined. Results: In our study, the number of injections in the 1st, 2nd, and 3rd years, respectively, was 4.2±2.0, 1.8±1.9, and 1.0±1.7 in the phakic group, and 3.9±2.0, 1.7±1.9, and 0.8±1.4 in the pseudophakic group. When the two groups were compared in terms of the number of injections, there was a statistically significant difference in the 1st year, but there was no significant difference in the 2nd and 3rd years (p=0.001, p=0.350, and p=0.288, respectively). There was no statistically significant difference between the groups in terms of CMT in the baseline, 6th, 12th, 24th, and 36th months (p=0.991, p=0.327, p=0.652, p=0.599, and p=0.873, respectively). Although there was no difference in VA between groups at the beginning (p=0.052), the phakic group showed statistically better VA in controls at 3rd, 6th, 12th, 24th, and 36th months (p=0.001, p=0.001, p=0.000, p=0.000, and p=0.003, respectively). Conclusion: Differences in the number of injections and visual results between phakic and pseudophakic patients in wet type AMD may necessitate the creation of different treatment and follow-up protocols.

Results of anti-VEGF treatment for neovascular AMD in eyes with different baseline visual acuity in Turkish population-based on real life data-Bosphorus retina study group.

BACKGROUND: To investigate the anatomical and visual outcomes of the patients with neovascular age-related macular degeneration (nAMD) treated with anti-vascular endothelial growth factor (anti-VEGF), according to the baseline best-corrected visual acuity (BCVA) based on the multicenter real-life data. METHODS: Five-hundred-ninety patients who had taken the Pro Re Nata (PRN) treatment regimen with three loading doses and at least one year of follow-up were included. The patients were divided into three groups according to the baseline BCVA: Group 1 (BCVA ≥ 1.3 Logmar), Group 2 (1.3 Logmar > BCVA ≥ 0.3 Logmar), and Group 3 (BCVA ≤ 0.2 Logmar). BCVA, central macular thickness (CMT), and the number of injections and visits were evaluated. RESULTS: There were 175, 322, and 93 patients in Group 1, Group 2, and Group 3, respectively. The number of visits and injections in the 1st year was not different between the groups (p = 0.58 and p = 0.08) and was 7.09 and 4.41 (Group 1), 6.59 and 5.58 (Group 2), 6.77 and 4.08 (Group 3). There was a significant difference in CMT between the baseline and 12th month in Group 1 and Group 2 (p < 0.001, p < 0.001, respectively) but not in Group 3 (p = 0.84). BCVA was significantly better in the 12th month in Group 1 (p < 0.001), slightly worse in Group 2 (p = 0.79), and significantly worse in Group 3 (p < 0.001). CONCLUSION: This study provides evidence that an inadequate number of injections cannot protect vision. Moreover, it can cause vision loss, especially in the eyes with good vision.

Evaluation of macular vascular density and foveal avascular zone changes by optical coherence tomography angiography (OCT-A) after intravitreal dexamethasone implant in diabetic macular edema resistant to Anti-VEGF treatment.

PURPOSE: Analysis of foveal avascular zone (FAZ) width and vascular density (VD) changes before and after intravitreal dexamethasone implant (IDI) treatment in diabetic macular edema (DME) patients resistant to anti-VEGF treatment. METHODS: In this retrospective study, patients who were regularly treated with at least 5 doses of intravitreal Anti-VEGF (bevacizumab, ranibizumab or aflibercept) for DME and whose DME continued were considered resistant to Anti-VEGF and were treated with IDI for the first time. Thirty-four eyes of 34 patients were included in the study. FAZ and VD values of optical coherence tomography angiography (OCT-A) scans at 0, 1 and 3 months were examined. RESULTS: In OCT-A measurements, the pre-IDI superficial plexus FAZ (SFAZ) area (0.350 ± 0.120 mm2) was decreased at 1 (0.292 ± 0.132 mm2, p < 0.001) and at 3 months (0.311 ± 0.153 mm2, p = 0.017). Pre-IDI deep plexus FAZ (DFAZ) area (0.651 ± 0.313 mm2) was decreased at 1-month post-IDI (0.481 ± 0.247 mm2, p < 0.001) while no significant change was observed at 3 months (0.575 ± 0.259 mm2, p = 0.197). There was no significant change in the mean post-IDI total VD rate in both superficial (pre 39.2% ± 2.4; 1st month 39.2% ± 2.6%; 3rd month 39.5% ± 3.4%) and deep retinal plexus (pre 43.3% ± 2.6%; 1st month 43.5 ± 2.8%; 3rd month 43.6% ± 4.6%) (p = 0.408 and p = 0.607, respectively). CONCLUSION: The study showed that IDI caused a significant decrease in the FAZ area without any change in VD in patients with DME resistant to the anti-VEGF agents. IDI might be related to a decrease in the macular ischemia secondary to diabetic retinopathy.

Prognostic factors affecting macular hole closure types.

PURPOSE: In this study, we aimed to evaluate the relationship between macular hole closure types assessed by optical coherence tomography (OCT) and the preoperative prognostic factors. MATERIALS AND METHODS: In total, 183 patients who underwent pars plana vitrectomy and internal limiting membrane peeling for idiopathic macular hole between August 2014 and August 2019 were reviewed retrospectively. The preoperative measurements of the macular hole including minimum linear diameter (MLD), basal hole diameter (BHD) and hole height (HH) were measured on OCT images. The patients were divided into two closure types on the basis of postoperative OCT findings (type 1 closure: retinal edges were flat and there was no defect of the neurosensory retina on the fovea; type 2 closure: retinal edges were flat and there was a defect of the neurosensory retina on the fovea). The difference of prognostic factors such as age; duration of symptoms; preoperative best-corrected visual acuity (BCVA); preoperative macular hole measurements, including MLD, BHD and HH; and rate of reopening between two types were statistically analysed. RESULTS: The mean age of patients was 66.33 ± 8.09 years (range: 48-88 years). According to OCT imaging, 117 eyes (63.9%) were classified into the type 1 closure group, and 66 eyes (36.1%) were classified into the type 2 closure group. There were no significant differences between two groups in age, duration of symptoms and preoperative BCVA (p = 0.694, p = 0.092 and p = 0.15). MLD and BHD were significantly larger, and reopening was significantly more common in type 2 group (p < 0.05, p = 0.04 and p < 0.005); however, there was no significant difference in HH between two groups (p = 0.239). CONCLUSION: Preoperative horizontal measurements of macular hole may help to determine postoperative visual expectations and anatomical success, and predict the possibility of reopening.

Choroidal vascularity index as an indicator of vascular status of choroid, in eyes with nanophthalmos.

PURPOSE: To investigate choroidal vascular index (CVI) in eyes with nanophthalmos (NO) with the use of optical coherence tomography (OCT). METHODS: Macular enhanced depth imaging OCT scans of 25 eyes of 25 patients with NO and age-gender-matched 25 eyes of 25 control subjects were analysed. Images were binarized using the ImageJ software, and total choroid area (TCA), luminal area (LA) and stromal area (SA) were acquired. The main outcome measure was CVI, defined as the ratio of LA to TCA. RESULTS: Twenty-five eyes of 25 patients with NO and age-gender-matched control subjects were enrolled. The mean TCA, SA and LA were found to be significantly higher in patients with NO (2.51 ± 0.44 vs. 1.91 ± 0.35 mm2, P < 0.001; 0.86 ± 0.17 vs. 0.63 ± 0.13 mm2, P < 0.001; and 1.65 ± 0.29 vs. 1.27 ± 0.23 mm2, P < 0.000, respectively). On the contrary, CVI did not significantly differ between the two groups (65.72, 67.68, P = 0.099). CONCLUSION: As a novel OCT-based marker, CVI could be used to assess vascular status of the choroid in eyes with NO and can provide better understanding of the pathogenesis of this disease.

Comparison of two different treatment regimens' efficacy in neovascular age-related macular degeneration in Turkish population-based on real life data-Bosphorus RWE Study Group.

AIM: To compare two different anti-vascular endothelial growth factor (anti-VEGF) treatment regimens'-a priori pro re nata (PRN) and PRN regimen following the loading phase-anatomical and functional results in neovascular age-related macular degeneration (nAMD) patients. METHODS: Totally 544 nAMD patients followed and treated with aflibercept (n=135) and ranibizumab (n=409) at 9 different centers between 2013 and 2015 were enrolled into this retrospective multicenter study. Patients with initial best corrected visual acuity (BCVA) interval of 1.3-0.3 (logMAR) and a minimum follow-up of 12mo were included. Patients under two different regimens-a priori pro re nata (1+PRN) or 3 consecutive intravitreal injections followed by a PRN regimen (3+PRN)-were compared in BCVA at 3th, 6th and 12th months, and in central macular thickness (CMT) at 6th and 12th months. The total study group, intravitreal ranibizumab (IVR) and intravitreal aflibercept (IVA) groups were evaluated separately. RESULTS: The mean CMT decreased in the 1+PRN (n=101) regimen from 407 to 358 and 340 µm and in the 3+PRN (n=443) group from 398 to 318 and finally to 310 µm at months 6 and 12, respectively. Anatomically, the CMT reduction at 6th month (48.5 vs 76.4; P<0.05) was statistically significant in favor of 3+PRN group. BCVA changed in 1+PRN group from 0.77 to 0.78, 0.75 and 0.75; in 3+PRN group from 0.81 to 0.69, 0.72, and 0.76 at months 3, 6, and 12, respectively. Visual gain was statistically better in 3+PRN group at 3th month (-0.01 vs 0.12; P<0.001). In IVR group, CMT reduction was in greater in 3+PRN at 6th (44 vs 72) and 12th month (61 vs 84), but statistically insignificant. The 3+PRN group revealed statistically better visual results at 3th month (-0.02 vs 0.11, P<0.05). In IVA group, although statistically insignificant, CMT reduction (61 vs 89, 6th month; 85 vs 97, 12th month) and visual gain (0.02 vs 0.16; 0.02 vs 0.14; 0.05 vs 0.11) was found in favor of 3+PRN group at all visits. CONCLUSION: The loading dose of anti-VEGF treatments in nAMD leads to significantly better anatomical and functional results, regardless of the agent, specially in early follow-up interval.

Evaluation of Choroidal Thickness in Patients with Proliferative and Non-Proliferative Macular Telangiectasia Using Enhanced Depth Imaging Optical Coherence Tomography.

Purpose: To compare subfoveal choroidal thickness (SFCT) in eyes with non-proliferative macular telangiectasia (MacTel) type 2 with or without subretinal neovascularization (SRNV) and healthy control eyes.Methods: Consecutive patients with non-proliferative and proliferative MacTel type 2 were included in the current study. For comparisons subjects with no ocular pathology were recruited and used as controls. Best corrected visual acuity (BCVA), central macular thickness (CMT), and subfoveal choroidal thickness (SFCT) were evaluated. Since axial length (AL) may affect choroidal thickness, AL measurements were performed to avoid confusion in SFCT between the groups.Results: Of the 63 eyes of 38 MacTel type 2 patients, 38 eyes had only MacTel type 2 (group 1) and 25 eyes had SRNV caused by MacTel type 2 (group 2). Fourty eyes of 20 subjects served as controls (group 3). BCVA was found to be significantly higher in control group compared with group 1 and group 2 (p < .005). Whereas, no difference was detected between group 1 and group 2 (p = .75). No difference was noted in CMT between the groups (p = .35). Axial length measurement was very similar among all three groups (p = .62). After adjusting for age and axial length SFCT was significantly thinner in group 3 than the other groups (p < .001), but no statistically significant difference was found between group 1 and group 2.Conclusions: Choroidal thickness did not vary between eyes with MacTel type 2 with SRNV and without SRNV. Choroid was significantly thicker in MacTel type 2 with SRNV and without SRNV than healthy eyes.

Morphological assessment of lamina cribrosa in idiopathic intracranial hypertension.

Purpose: Technological development of optic coherence tomography has enabled a detailed assessment of the optic nerve and deeper structures and in vivo measurements. The aim of this study was to compare the lamina cribrosa morphology of the optic nerve in idiopathic intracranial hypertension (IIH) and healthy individuals. Methods: The lamina cribrosa morphology of optic nerve in 15 eyes with IIH and 17 eyes of healthy individuals were compared. Four parameters such as Bruch membrane opening (BMO), lamina cribrosa thickness (LCT), prelaminar tissue thickness (PTT), and anterior lamina cribrosa surface depth (ALCSD) were retrospectively evaluated. Results: By enhanced depth imaging-optic coherence tomography (EDI-OCT), PTT and BMO were found to be significantly greater (574,35 ± 169,20 µm and 1787,40 ± 140,87 µm, respectively) in IIH patients than healthy individuals (187,18 ± 132,15 µm and 1632,65 ± 162,58 µm, respectively), whereas ALSCD was found to be significantly less in IIH patients (234,49 ± 49,31 µm) than healthy individuals (425,65 ± 65,23 µm). There was not a statistically significant difference regarding LCT between the IIH patients (238,59 ± 17,31 µm) and healthy individuals (244,96 ± 15,32 µm). Conclusion: Increased intracranial pressure causes morphological changes in lamina cribrosa. Assessment of lamina cribrosa with EDI-OCT is important for diagnosis and follow-up of patients with IIH. EDI-OCT is objective, reproducible, and cost-effective assistive imaging tool in IIH patients.

Clinical Use of Dexamethasone Implants in Resistant Macular Edema Secondary to Branch Retinal Vascular Occlusion Compared with Intravitreal Anti-Vascular Endothelial Growth Factor.

OBJECTIVES: Branch retinal vein occlusion (BRVO) is the second most common type of retinal vascular disorder. Both inflammation and increased vascular endothelial growth factor (VEGF) levels play important roles in the pathogenesis of macular edema (ME) secondary to BRVO. The aim of this study was to compare the efficacy of 0.7-mg intravitreal dexamethasone implants with continued anti-VEGF treatment in patients with ME secondary to BRVO who were poor responders to at least 6 previous anti-VEGF injections. METHODS: Patients exhibiting an insufficient response to at least 6 ranibizumab treatments and who subsequently underwent a dexamethasone implant were included Group 1. Patients who were at risk for cataract or glaucoma continued treatment with the same drug and were defined as Group 2. The best corrected visual acuity (BCVA) and central macular thickness (CMT) changes at month 2, 4, and 6 were measured. RESULTS: Ninety eyes were evaluated. In Group 1, the mean baseline BCVA of 0.71±0.75 logarithm of the minimum angle of resolution (logMAR) improved to 0.53±0.62 logMAR at month 2 (p<.001), 0.67±0.72 logMAR at month 4 (p=0.325), and 1.03±0.83 logMAR at month 6 (p=.001). In Group 2, the mean baseline BCVA was 0.73±0.83 logMAR, and improved to 0.68±0.83 logMAR at month 2 (p=0.12), 0.698±0.81 logMAR at month 4 (p=0.270), and 0.76±0.80 at month 6 (p=0.546). The baseline CMT in each group was 588±176 µm and 545±165 µm, respectively (p=0.248). The mean CMT of Group 1 changed from a baseline measurement of 588±176 µm to 308±132 µm at month 2 (p<.001), 450±195 µm at month 4 (p<.001), and 510±190 µm at month 6 (p<.001). The mean CMT of Group 2 changed from a baseline value of 545±165 µm to 486±162 µm at month 2 (p<.001), 516±168 µm at month 4 (p<.001), and 528±171 µm at month 6 (p=0.037). CONCLUSION: Dexamethasone implants were a more effective treatment for patients with BRVO-related resistant ME than ranibizumab at month 2. However, this positive effect seems to decline rapidly in the long term.

Foveal avascular zone area measurements with optical coherence tomography angiography in patients with nanophthalmos.

PURPOSE: To compare the area of the superficial foveal avascular zone (SFAZ) and deep foveal avascular zone (DFAZ) between patients with nanophthalmos and age matched controls. METHODS: This prospective and comparative study included 19 eyes from 11 patients with nanophthalmos (study group) and 19 eyes from 19 healthy subjects (control group). SFAZ and DFAZ were measured with optical coherence tomography angiography (OCT-A). All participants underwent a standardised ocular examination including best corrected visual acuity (BCVA), central macular thickness (CMT), subfoveal choroidal thickness (SFCT) anterior chamber depth (ACD), axial length (AL), and refractive error (RE) measurements. RESULTS: Mean SFAZ and DFAZ area in the nanophthalmic eyes and in the control eyes were 0.09 ± 0.12 mm2, 0.10 ± 0.10 mm2 and 0.37 ± 0.10 mm2, 0.37 ± 0.10 mm2 respectively (p < 0.001 and p < 0.001). Mean BCVA, RE, AL, ACD CMT, SFCT, were 0.40 ± 0.34 logMAR Unit, 10.0 ± 2.2 18.1 ± 1.5 mm, 2.15 ± 0.28 mm, 367.1 ± 87.4 µm, 489.2 ± 85.2 µm respectively, in nanophthalmic eyes and there was a statistically significant difference between groups (p < 0.001 for each). There were negative correlations for both SFAZ and DFAZ with RE (r = -0.733 and r = -0.758, p < 0.001), CMT (r = -0.823 and r = -0.82, p < 0.001), SFCT (r = -0.647 and r = -0.717 p < 0.001) for the entire study population. SFAZ and DFAZ area were significantly correlated with AL (r = 0.732 and r = 0.745, p < 0.001) and ACD (r = 0.614 and r = 0.654, p < 0.001). In study group, 5 eyes did not have neither SFAZ nor DFAZ, 3 eyes had only DFAZ and 1 eye had only SFAZ in the OCT-A images. CONCLUSIONS: SFAZ and DFAZ area were significantly smaller in nanophthalmic eyes than control eyes.

Real-World Outcomes of Anti-VEGF Treatment for Neovascular Age-Related Macular Degeneration in Turkey: A Multicenter Retrospective Study, Bosphorus Retina Study Group Report No: 1.

OBJECTIVES: To evaluate the real-world outcomes of intravitreal anti-vascular endothelial growth factor (anti-VEGF) treatment in neovascular age-related macular degeneration (nAMD) patients. MATERIALS AND METHODS: Multicenter, retrospective, interventional, non-comparative study. The records of nAMD patients treated with an anti-VEGF agent on a pro re nata treatment regimen basis between January 2013 and December 2015 were reviewed. The patients who completed a follow-up period of 12 months were included. Primary outcome measures of this study were the visit and injection numbers during the first year. RESULTS: Eight hundred eighty eyes of 783 patients met the inclusion criteria for the study. Mean number of visits at month 12 was 6.9±2.5 (range: 1-15). Mean number of injections at month 12 was 4.1±1.9 (range: 1-11). Mean visual acuity at baseline and months 3, 6, and 12 was 0.90±0.63 LogMAR (range: 0.0-3.0), 0.79±0.57 LogMAR (range: 0.0-3.0), 0.76±0.57 LogMAR (range: 0.0-3.0), and 0.79±0.59 LogMAR (range: 0.0-3.0), respectively. Mean central retinal thickness at baseline and months 6 and 12 was 395±153 µm (range: 91-1582), 330±115 µm (range: 99-975), and 332±114 µm (range: 106-1191), respectively. CONCLUSION: The numbers of visits and injections were much lower than ideal and were insufficient with the pro re nata treatment regimen.

The real life data of ranibizumab use among the diabetic macular edema patients in Turkey: Documenting the improvement with clinical optimization during three consecutive years.

PURPOSE: To report the 12 month real life outcomes of ranibizumab treated diabetic macular edema (DME) patients. METHODS: Treatment naïve DME patients treated with ranibizumab were included. Patients were divided into three groups according to their hospital admittance years (2013, 2014, and 2015) and were compared in regards to the treatment outcomes. RESULTS: The mean visual acuity change from baseline to month 12 was not statistically significant in 2013 at month 12. The mean BCVA change from baseline to month 12 was statistically better at month 12 in 2014 and 2015. There was a statistically significant difference among the three groups in regards to both mean visit and injection numbers. The mean visit number in 2013 and 2014 were both lower than 2015. The mean injection number in 2013 was lower than both 2014 and 2015. CONCLUSIONS: It is effortful to obey the strict follow-up criteria of prospective studies in DME patients on a PRN regimen. However, optimizing the clinical processes of patient management may lead to improved clinical outcomes in real life.

Prognostic value of ocular trauma score for open globe injuries associated with metallic intraocular foreign bodies.

BACKGROUND: The prognostic value of the ocular trauma score (OTS) in patients who underwent 23-gauge pars plana vitrectomy (23-G PPV) for surgical removal of posterior segment metallic intaocular foreign bodies (IOFB) was evaluated. METHODS: Patients who underwent 23-G PPV for surgical removal of retained metallic IOFBs were retrospectively analyzed. OTS score for each patient was calculated and raw scores were converted to their corresponding OTS categories. The final VAs in study patients were compared with their respective OTS categories. RESULTS: Twenty-five eyes from 25 patients were examined. Twenty-four (96%) of the patients were male, and the mean age was 34 ± 12 years. The time from injury to 23-G PPV was 9 ± 4 days. Fourteen (56%) patients had zone 1 trauma, eight (32%) patients had zone 2 trauma, and three (12%) patients had zone 3 trauma. Postoperative visual acuity was ≥ 20/200 in 14 (56%) of the patients and ≥ 20/40 in seven (28%) eyes. At the final visit, anatomical success was achieved in 86% of patients with retinal detachment at presentation. No statistically significant differences were found between our final VAs and OTS scores. CONCLUSION: OTS, which provides prognostic information after general ocular trauma, may also provide valuable prognostic information for patients who undergo 23-G PPV for the surgical removal of metallic posterior segment IOFBs.

Pediatric Traumatic Retinal Detachment: Clinical Features, Prognostic Factors, and Surgical Outcomes.

PURPOSE: We report the clinical characteristics, prognostic factors, and surgical outcomes for 23-gauge pars plana vitrectomy (23-G PPV) in pediatric cases of traumatic retinal detachment (RD). METHODS: Medical records of pediatric patients who underwent 23-G PPV to treat traumatic retinal detachment were retrospectively reviewed. These patients underwent a follow-up examination at least 1 year following surgery. Associations between various preoperative factors and anatomical and visual outcomes were analyzed. An Ocular Trauma Score (OTS) and a Pediatric Ocular Trauma Score (POTS) were calculated for each patient. Raw scores were converted to their corresponding OTS and POTS categories. Final visual acuities by categories were compared with those in the OTS and POTS studies. RESULTS: The mean age of the patients was 9 ± 4 years, and the male-to-female ratio was 4.7 : 1. The mean follow-up time was 23 ± 14 months. Anatomical success was achieved in 72% of the eyes, and functional success (>5/200) was achieved in 37% of the eyes. Functional success was less common among patients with visual acuities less than hand motion, macula-off retinal detachment, proliferative vitreoretinopathy at presentation, and recurrent retinal detachment during follow-up. When we compared the categorical distribution of final visual acuities in all categories, our results were significantly different than those suggested by OTS and POTS. CONCLUSIONS: Visual outcomes are poorer compared to anatomical outcomes. OTS and POTS do not provide reliable prognostic information if the patient has RD. Presenting visual acuity, the presence of macula-off RD, and PVR are all important predictors of final visual acuity.
