Primary 25-gauge transconjunctival sutureless vitrectomy in pseudophakic retinal detachment
No full textAims: There are few reports on 25-gauge transconjunctival sutureless vitrectomy (TSV) in cases of pseudophakic retinal detachment. We conducted this study to report the anatomic and functional outcomes of 25-gauge TSV in the treatment of primary pseudophakic retinal detachment (RD). Design: Prospective, interventional case series. Materials and Methods: Fifteen eyes of 15 patients with RD after cataract surgery with phacoemulsification were evaluated. Primary pseudophakic RDs with macular detachment and proliferative vitreoretinopathy Stage B or less were included in the study. Pars plana vitrectomy with the 25-gauge TSV system, perfluorocarbon liquid injection followed by air exchange, endolaser photocoagulation and sulfur hexafluoride gas (20%) injection were applied to all eyes. Results: Mean follow-up time was 9.2 months (range, six to 12 months). Retinal reattachment with a single operation was achieved in 93% of eyes and with additional surgery, the retina was reattached in 100% of eyes. Preoperative visual acuity was less than 20/200 in all eyes (range, hand motions to 20/400). Postoperative visual acuity was 20/40 or better in eight eyes (53%) and between 20/50 and 20/200 in seven eyes (47%). No severe hypotony was encountered and no sutures were required to close the scleral and conjunctival openings. Postoperative complications were macular pucker in one eye (7%) and cystoid macular edema in another eye (7%). Conclusions: Primary 25-gauge TSV system appears to be an effective and safe procedure in the treatment of uncomplicated pseudophakic RD

Patients and methods: In this retrospective consecutive case series, patients who underwent 23 G TSV for severe DFVP between October 2011 and March 2014 at our institution were evaluated. 23 G TSV was performed with a high-speed (5,000 cuts per minute) cutter without a chandelier light. Results: The mean follow-up period was 8 months (range: 4–23 months). Of the 27 eyes of 27 patients, 14 eyes (52%) underwent concomitant phacoemulsification with posterior chamber intraocular lens implantation, nine eyes (33%) were pseudophakic, and four eyes were phakic (15%). DFVP was removed with ease in all, and visual acuity was improved in 18 (67%) eyes. Iatrogenic retinal tear was observed in four eyes (15%) and treated successfully during surgery. Suture placement to a single sclerotomy was performed in eight eyes (30%). Postoperative intraocular hemorrhage was observed in five eyes (18%). Cataract formation was observed in two of the four phakic eyes. Three (11%) patients had postoperative intraocular pressure rise. Postoperative hypotony (≤6 mmHg) and endophthalmitis were not observed in any eye. Conclusion: The segmentation and removal of fibrovascular membranes with high-speed 23 G TSV seems to be a safe and easy method in severe diabetic eye disease. Keywords: diabetic fibrovascular proliferation, transconjunctival sutureless vitrectomy, high spee

Bariatric surgery might aggravate proliferative diabetic retinopathy
No full textPurpose This study aimed to assess the changes experienced by patients with proliferative diabetic retinopathy (PDR) after bariatric surgery (BS). Methods This retrospective observational study includes 37 eyes of 21 patients with PDR who underwent BS at a tertiary university hospital over the period of 2014-2018. The control group (CG) comprised 37 eyes of 27 patients with PDR who attended the same research hospital for diabetes care without undergoing BS. Preoperative and postoperative glycated haemoglobin (HbA1c) levels, weight and diabetic retinopathy screening results were collected from the medical records of the patients. Patients who had undergone preoperative retinal screening and at least one postoperative retinal screening were included in the analysis. Results Both groups exhibited statistically significant visual acuity (VA) loss at 6 months and 1 year (p < 0.001). At postoperative 6 months the VA loss experienced by the control BS group was significantly more severe than that experienced by the CG (p = 0.03). The first-year HbA1c levels of the BS group were significantly lower than those of the CG (p = 0.02). The BS group had significantly higher intraocular haemorrhage (p = 0.04), neovascular glaucoma (p = 0.04) and retinal vein occlusion (p = 0.04) rates than the CG group. All complications occurred at different patients. Conclusion Patients with PDR who received BS showed more severe retinopathy than patients who were matched for age, sex, HbA1c levels and follow-up duration and who did not receive BS
Top 50 Most-Cited Publications on Blepharoplasty Surgery Between 2015 and 2022: From a Current Altmetric Perspective of Research Impact
No full textBackground Blepharoplasty is one of the most-performed esthetic operations, and social media platforms have become an influential tool for distributing scientific information. Because the internet has gained popularity among medical experts and surgeons to connect with the public, we aimed to evaluate the altmetric–bibliometric analysis of the top 50 most-cited articles on blepharoplasty surgery between 2015 and 2022 and assess correlations with various metrics.
Methods “Blepharoplasty” was searched using the WoS database, and the altmetric score was obtained. Co-authors, keywords, country of authors, and cited journal network map analysis were created using VOSviewer for the 485 publications retrieved. The articles' focus was examined quantitatively and the most prolific parameters were identified.
Results The most research was performed by the USA, the most productive institution was the “University of California System,” and the most prolific author was “Wonn CH.” The number of citations ranged from 37 to 9, and altmetric attention scores ranged from 54 to 0. The most articles and citations peaked in 2021. Altmetric and Twitter scores were moderately correlated with journal metrics but there were no correlations with citation counts.
Conclusion The first comprehensive altmetric analysis on blepharoplasty surgery offers new guidelines for upcoming articles by demonstrating the recent investigation trends, prolific parameters, and zones with potential for the public's attention and education, providing valuable data regarding the distribution of scientific knowledge in social media platforms and to the general public. A social network may be used to increase the visibility of scientific articles apart from creating brands and markets
Pediatrik Regmatojen Retina Dekolmanı ve Tedavisi
No full textPediatrik yırtıklı retina dekolmanı ortaya koyduğu klinik özellikler ve bunların gerektirdiği tedavi prensipleri nedeniyle erişkin dönem yırtıklı dekolmanlarından farklıdır. Arka vitreus ayrılmasının bulunmaması, retinal holler ve diyaliz gibi retinal patolojilere bağlı olarak gelişen dekolman bu faklılıklar arasında sayılabilir. Yavaş klinik seyir, pediatrik yaş grubunda görme kaybının geç fark edilmesi gibi etkenler hastaların çeşitli seviyelerde proliferatif vitreoretinopati ile başvurmasına neden olmaktadır. Hastaların fakik olması, genç gözün abartılı yara iyileşmesi yanıtı tedavi sürecini değiştirmekte, cerrahi yöntemlerin erişkinlere göre farklı sıralamayla ya da kombinasyon tedavileri ile uygulanmasını gerekli kılmaktadır. Skleral çökertme cerrahisi pediatrik yırtıklı retina dekomanlarının yönetiminde primer tedavi yöntemi olarak uygulanmaktadır. Retinal deliklerin yerleşimi ve proliferatif vitreoretinopatinin seviyesine göre çevresel ya da lokal çökertme gibi farklı şekillerde uygulanabilir. Tedaviye verilen yanıta ya da proliferatif vitreoretinopatinin derecesine göre gerektiğinde vitrektomi cerrahisi de eklenebilir. Hastaların fakik, vitreus tabanın aşırı posterior yerleşimli olması ya da ameliyat esnasında başarılı arka hiyaloid ayrılmasına rağmen mikroskobik düzeyde hiyalosit hücrelerinin retina yüzeyinde kalması vitrektomi cerrahisini zorlaştıran etmenler olarak karşımıza çıkar. Final retinal yatışma oranları erişkinlerden daha düşük olurken birden fazla cerrahi uygulanma ihtimali de fazladır. Travma dışındaki etiyolojilerde retinal yırtıklar ve predispozan lezyonların sıklıkla bilateral olması nedeniyle sağlam gözün muayene edilerek gerektiğinde koruyucu lazer uygulanması önemlidir.Pediatric rhegmatogenous retinal detachments have a different clinical presentation and different treatment algorithms than adult rhegmatogenous retinal detachments. The absence of posterior vitreus detachment and the predominance of retinal holes and dialysis in the etiology can be counted among these differences. Slow onset of visual loss and the inability of the pediatric age group to appreciate the symptoms leads to the development of variable amounts of proliferative vitreoretinopathy at clinical presentation. The presence of the crystalline lens and exaggerated wound healing response of the young eye changes the usual treatment approach of the adult detachments, and combination surgeries are frequently required. Scleral buckling surgery is the primary treatment option in the pediatric age group. It may be applied segmentally or circumferentially according to the level of the retinal breaks and the extent proliferative vitreoretinopathy present. Vitrectomy may be added according to the treatment response or the level of proliferative vitreoretinopathy present. Phakic lens status, abnormally posterior insertion of posterior vitreus base, and hyalocyte cellular remnants despite successful intraoperative posterior vitreus detachment are the obstacles that may be encountered in vitrectomy for pediatric retinal detachment. Pediatric rhegmatogenous retinal detachments require a higher number of surgeries per patient and have a lower final retinal attachment rate than adult cases. Examination and prophylactic treatment of the fellow eye must be carried out as the underlying retinal breaks and predisposing lesions are frequently bilateral with the exception of trauma in this age group

Early retinal changes after uncomplicated mild and hard cataract surgery
No full text© 2018, Yuzuncu Yil Universitesi Tip Fakultesi. All rights reserved.To evaluate and compare the possible effects of hard and soft nuclear cataract surgeries in the development of early postoperative retinal complications. In a retrospective study design 1388 uncomplicated phacoemulsification surgery were enrolled in the study. Data for 688 Grade 5-6 and 700 Grade 2-3 nuclear cataracts according to Lens Opacities Classification System III (LOCS III) were used for comparison. All patients were evaluated for visual acuity (VA), intraocular pressure (IOP), central macular pathologies and angiographic fluid leakage pattern at 1 week and 1 month. Biomicroscopic evaluation, optical coherence tomography (OCT), fleuroscein angiography (FA) and indocyanine green angiography (ICG) were used for examination. Follow up time was 1 month. Mean CMT of patients were higher at hard cataracts but not statistically significant (p>0.24). Clinically significant cystoid macular edema after hard nuclear cataract surgery was 1.59 %(11) and 1.28 %(9) for soft cataracts (p>0.05). After 20/20 visual acuity at 1 week, 5 (0.72 %) patients from hard nuclear group had visual loss and hemorrhagic pigment epitelial detachment (PED) at 1 month control. Angiographic evaluations revealed them 4 as insignificant polypoid choroidal vasculopathy (PCV). One of them is still controversial. IOP and VA results were similar at both controls (p> 0.05). Subretinal hemorrhage after cataract surgery may be the first sign of some PCV patients. Patients who were diagnosed with PCV should be carefully evaluated for cataract surgery. Hard nuclear cataract may be a predisposing factor for early hemorhagic PED in patients with PCV. Any retinal pathology should be carefully evaluted before cataract surgeries
