Background and Objectives: Lateral osteotomies in rhinoplasty run adjacent to the lacrimal drainage system (LDS), risking postoperative tearing. Piezoelectric (piezo) devices enable precise bone cuts that may reduce LDS trauma. We compared the 1-month incidence of objective lacrimal dysfunction after piezo versus classic osteotomy. Materials and Methods: Retrospective, single-center controlled cohort (1 January 2024–1 January 2025) at a tertiary ENT clinic. Consecutive patients aged 19–45 with pre-operative paranasal sinus CT and no prior lacrimal disorder were grouped by osteotomy technique (piezo vs. classic; n = 65 per arm). Assessments were performed at postoperative day 7–10 and at 1, 3, and 6–12 months. The primary endpoint was 1-month objective lacrimal dysfunction, defined as fluorescein dye disappearance test (FDDT) grade ≥1 or reflux/resistance on irrigation plus symptoms (Munk ≥2). Pre-specified statistical tests were used. Results: Early tearing favored piezo. At week 1, epiphora occurred in 32.3% with piezo versus 46.1% with classic (p = 0.041); by month 6, rates were 4.6% versus 15.1% (p = 0.031). Differences at months 1 and 3 also favored piezo but were not statistically significant (p = 0.062 and p = 0.088). FDDT positivity was lower with piezo at week 1 (23.0% vs. 38.4%, p = 0.045) and month 6 (3.0% vs. 10.7%, p = 0.048). Irrigation obstruction was less frequent with piezo at week 1 (7.6% vs. 21.5%, p = 0.026), but groups converged by months 1 (15.4% vs. 12.3%, p = 0.80) and 3 (6.2% vs. 4.6%, p > 0.99). Punctum stenosis/occlusion remained uncommon in both groups without significant differences. Conclusions: Piezo-assisted lateral osteotomy is associated with less early lacrimal dysfunction and lower 6-month epiphora compared with the classic technique. Convergence of irrigation findings by 1–3 months suggests postoperative edema as the dominant transient mechanism. Given the retrospective, single-center design and low event rates, multicenter prospective studies powered for early LDS outcomes are warranted.

We aimed to examine the effect of strabismus surgery on quality of life levels in children and adolescents. The Health-Related Quality of Life Inventory version 4.0 (HRQOL 4.0), consisting of 23 questions and 4 subscales (physical functioning, emotional functioning, social functioning, and school problems), was administered to the children and adolescents who underwent strabismus surgery and their parents between December 2024 and June 2025, at preoperative and postoperative 1st and 3rd months. The postoperative deviation angle of the cases was 10 Prism Diopter (PD) or less. Strabismus surgery was performed by an Ophthalmologist, and the scales were evaluated by a Child and Adolescent Psychiatrist. 27 cases were included in our study. 17 (62.9%) of the cases were girls and 10 (37.1%) were boys. The average age was 9.0 ± 3.9 (7–17) . In child and adolescents, the change in the physical functionality parameters of the cases was not statistically significant (p >0.05), but the change in the parameters of emotional functionality, social functionality and school-related problems between the preoperative, postoperative 1st month and postoperative 3rd month was statistically significant (p < 0.05). In the parents’ proxy opinion of the child, the change in physical functionality, emotional functionality, social functionality parameters between preoperative, postoperative 1st month and postoperative 3rd month was statistically significant (p < 0.05), but in the parameters of school-related problems, preoperative, postoperative 1st month and postoperative 3rd month were statistically significant. The change between was not statistically significant(p >0.05) (Table 2). Successful surgery for strabismus results in measurable improvement in the quality of life in children and adolescents and in the parents proxy opinion of the child’s quality of life.

AMAÇ: Diyabet endotel disfonksiyonu ve ateroskleroza neden olan sistemik bir hastalıktır. Diyabetik retinopati(DRP) nedeni ile takipli erkek olgularda ve DRP olmayan diyabetli erkek olgularda erektil disfonksiyon (ED) sıklığının değerlendirilmesi amaçlanmıştır. GEREÇ VE YÖNTEM: Çalışmamızda grup 1’de DRP’si olan, grup 2’de DRP’si olmayan fakat diyabeti olan, grup 3’de sağlıklı olguların olduğu kontrol grubuna ayrıldı. Tüm olgularda ED değerlendirilmesi için Uluslararası Erektil İşlev Formu anketi uygulanmıştır. Bu ankete göre skoru (0-10) arasında olanlar ciddi; (11-16) olanlar orta; (17-21) olanlar hafif-orta; (22-25) olanlar hafif; (26-30) ED yok olarak değerlendirildi. BULGULAR: Çalışmaya grup 1’de 25 olgu, grup 2’de 25 olgu ve grup 3’de 25 olgu olmak üzere toplam 75 olgu dahil edilmiştir. Anket skorlamasına göre grup 1’de; 2 (%8)’sinde ED yok, 3 (%12)’ünde hafif ED, 18 (%72)’inde hafif-orta ED, 1 (%4)’inde orta ED, 1(%4)’inde ciddi ED olduğu gözlenmiştir. Grup 2’de ;15 (%60)’inde ED yok, 3 (%12)’ünde hafif ED, 5 (%20)’inde hafif-orta ED, 1 (%4)’inde orta ED, 1 (%4)’inde ciddi ED olduğu gözlenmiştir. Grup 3’de ise 1 (%4)’inde hafif-orta ED, 4(%16)’ünde hafif ED, 20 (%80)’sinde ED yok olarak gözlemlenmiştir. Yaş arttıkça ED derecesinde artış gözlenmiştir (p<0.05). Diyabet, DRP olsun ya da olmasın ED oluşumunu kontrol grubuna göre arttırmaktadır (p<0.05). SONUÇ: Diyabet, mikrovasküler hasar ve nöropati oluşturarak hastalarda hayat kalitesini etkileyen ciddi sonuçlar doğurmaktadır. ED, diyabetli hastalarda özellikle retinopati gelişmiş ise daha sık görülmekte ve bu hastaların yaşam kalitesini düşürmektedir. Diyabet hastalarında DRP gelişmese bile ED gelişimi artmaktadır.

Background: To assess macular layer thickness, macular vessel density, and foveal avascular zone (FAZ) parameters in prediabetic patients compared with healthy normoglycemic controls using optical coherence tomography angiography (OCTA). Methods: Thirty prediabetic patients (group A; fasting plasma glucose 100-125 mg/dL, postprandial plasma glucose 140-199 mg/dL, glycated hemoglobin 5.7%-6.4%) and 30 age-matched normoglycemic subjects (group B) were included. The OCTA imaging was used to evaluate superficial capillary plexus (SCP) and deep capillary plexus (DCP) vessel densities, as well as FAZ area and perimeter. Participants with poor image quality, high refractive error, glaucoma, prior intraocular surgery, chorioretinal atrophy, or other ocular/systemic comorbidities were excluded. Results: The SCP and DCP perfusion densities (PDs) were lower in the prediabetic group, with significant reductions in the inferior and temporal quadrants of the DCP and the temporal quadrant of the SCP (P < .05). The FAZ area and perimeter were larger in the prediabetic group but not statistically significant (P > .05). Macular thickness was greater in all quadrants in group A, with significant thickening in the nasal and inferior quadrants (P < .05). Conclusion: Prediabetic patients demonstrated early microvascular and structural changes, including reduced macular PD, increased macular thickness, and FAZ enlargement. These findings suggest subclinical retinal involvement in prediabetes, warranting larger longitudinal studies. Cite this article as: Utlu B, Utlu ES, Çinici E, Akgöz H, Bayrakçeken K, Kozan BD.

Purpose: Objective: We aimed to investigate the attitudes of ophthalmologists toward the excessive amount of waste generated during modern cataract surgery practices. Methods: Survey study and a prospective, cross‐sectional, descriptive study. An online questionnaire consisting of 23 questions was directed to ophthalmologists practicing in Erzurum Province and its surroundings. Duplicate responses were prevented by allowing only one submission to the survey. Participants were asked to complete the questionnaire only if they performed cataract surgery. Results: The study included 102 ophthalmologists through an online survey. Approximately 43% of the participants performed between 200–500 cataract surgeries per year. 90% of the respondents believed that operating room waste was excessive and should be reduced. Among the drivers of waste/garbage generation in the study, the most common response (78%) was the widely recognized safety benefits of disposables. Again, when asked about the main drivers for using disposable instruments in ophthalmic surgery, the most common response was reduced liability (77%). 80% of respondents said that device and supply manufacturers should consider the environmental/carbon footprint in product design. When asked to what extent it reduces your willingness to use a material or medication in more than one patient, the highest preferred answer was the risk of endophthalmitis, while the least preferred answer was decreased efficiency. Conclusion: In conclusion, most ophthalmologists agree that a lot of waste is generated during surgery and that more widespread use of sterilizable materials rather than disposables could reduce waste.
