The objective of this study was to evaluate the anatomical and functional outcomes of patients who underwent relaxing retinotomy or retinectomy for retinal detachment complicated by proliferative vitreoretinopathy. The medical records of all patients who underwent retinectomy for retinal detachment complicated with proliferative vitreoretinopathy between 2015 and 2023 were reviewed retrospectively. The patients' mean age was 60.83 ± 16.4 (21-90) years. The study population consisted of 28 male (42.4%) and 38 female (57.6%). The mean follow-up period was 21.72 ± 13.44 (12-65) months. The mean initial visual acuity was 2.1 ± 0.63 logMAR, while the mean final visual acuity was 1.94 ± 0.69 logMAR (p = 0.094). Twenty-one patients presented with rhegmatogenous retinal detachment (31.8%), 36 with tractional retinal detachment due to diabetes (54.5%), and nine with retinal detachment secondary to trauma (13.6%). Visual acuity increased in 30 patients (45.45%), decreased in 10 patients (15.15%), and did not change in 26 patients (39.39%). Mean intraocular pressure (IOP) values were 13.25 ± 4.67 mmHg (range 5-28) at baseline and 12.98 ± 4.75 mmHg (range 4-25) at the final examination. Twenty-seven patients underwent 90-degree retinectomy (40.9%), 18 underwent 180-degree retinectomy (27.3%), 6 underwent 270-degree retinectomy (9.1%), and 15 underwent 360-degree retinectomy (22.7%). When evaluating proliferative retinal detachment by etiology (rhegmatogenous, traumatic, diabetic), no statistically significant differences were observed in baseline and final visual acuity or intraocular pressure (p > 0.05), nor in recurrence rates (p = 0.42). The findings of this study indicate that retinectomy is a beneficial treatment for cases of difficult retinal detachment, particularly when there is a need for both functional vision and retinal stabilization.

To investigate the effects of laparoscopic sleeve gastrectomy (LSG), a common subtype of metabolic and bariatric surgery (MBS), on corneal densitometry (CD) and lens densitometry (LD). This prospective, single-center study included 58 eyes of 58 obese participants. Preoperative and 6-month postoperative CD, LD, and anterior segment parameters were evaluated using Pentacam topography. The primary outcomes were changes in CD and LD six months after surgery. A total of 58 eyes from 58 participants, with a mean age of 36.76 ± 10.79 years, were evaluated. Six months following LSG, the average body mass index (BMI) decreased from 43.4 ± 6.6kg/m2 to 31.54 ± 5.13kg/m2 (p < 0.001). Central corneal thickness (CCT), intraocular pressure (IOP), CD, and LD decreased significantly six months after LSG (p < 0.001). The anterior chamber depth (ACD) and angle (ACA) significantly increased six months after LSG (p < 0.001 for all parameters). Correlation analyses showed a moderate positive association between changes in CD and LD, whereas only weak correlations were observed between changes in ocular and metabolic parameters. LSG was associated with significant changes in CD, LD, and anterior segment parameters, suggesting a positive effect on ocular tissue transparency. Not applicable.

To compare early postoperative dry eye outcomes in contralateral eyes of the same patients undergoing Keratorefractive Lenticule Extraction (KLEx) versus Femtosecond Laser-Assisted Laser In Situ Keratomileusis (FS-LASIK), with tear film osmolarity defined as the primary outcome measure. This study was conducted at Dunyagoz Izmır Hospital and involved patients who underwent corneal refractive surgery between June 2021 and December 2024. Patients with pre-existing dry eye disease were excluded from the study. Patients underwent KLEx in one eye and FS-LASIK in the fellow eye. Tear film osmolarity (primary outcome) was measured preoperatively and postoperatively using the TearLab® system. Secondary outcome measures included tear break-up time (tBUT) and subjective symptoms assessed via the Ocular Symptom Questionnaire Scores (OSDI). A total of 34 eyes of 17 patients (7 females and 10 males) were evaluated. Group 1 (KLEx) included 17 eyes and group 2 (FS-LASIK) included contralateral 17 eyes. The mean postoperative follow-up period was 34.2 days. Mean tear osmolarity was 297.7 ± 8.3 mOsm/L in the group 1 and 315.3 ± 10.2 mOsm/L in the group 2 (p < 0.001). Mean tBUT was 10.3 ± 3.1s for group 1 and 7 ± 2.32s for group 2 (p < 0.001). The mean postoperative OSDI scores were 32.5 for group 1 and 42 for group 2, with a preoperative baseline of 10.2 (both groups; p < 0.001). KLEx demonstrated superior early postoperative ocular surface stability compared to FS-LASIK in contralateral eyes. The procedure resulted in significantly less tear hyperosmolarity and better subjective comfort, suggesting it may be a preferable surgical option for minimizing dry eye induced by corneal refractive surgery.

BackgroundTranscatheter aortic valve implantation is the standard treatment for high-risk elderly patients suffering from symptomatic severe aortic stenosis. While this procedure is significantly less invasive compared to traditional methods, there are concerns regarding the potential risk of cerebrovascular accidents and ocular complications. We report a case of monocular central retinal artery occlusion that occurred following transcatheter aortic valve implantation due to aortic stenosis. The occurrence of central retinal artery occlusion post-transcatheter aortic valve implantation has not previously been reported.Case presentationA 78-year-old male presented with a sudden, painless loss of vision in the left eye immediately after undergoing transcatheter aortic valve implantation. Fundus examination revealed moderate optic disc edema, mild venous tortuosity and diffuse retinal pallor at the posterior pole, most marked in the perimacular region and extending along the major vascular arcades into the mid-peripheral retina, with a cherry-red spot at the fovea. Optical coherence tomography indicated signs of retinal ischemia. The patient was referred to the emergency department for further assessment.ConclusionsAlthough there is evidence of embolization occurring after TAVI, this is the first case of central retinal artery occlusion that has been reported. Our findings underscore the need for thorough pre-TAVI counseling, increased neurologist awareness of this complication, and prompt ophthalmologic evaluation in cases of sudden monocular visual loss.
