Aim: To evaluate the demographic and clinical characteristics of patients who underwent pars plana vitrectomy (PPV) for intraocular lens (IOL) dislocation into the vitreous cavity and the visual and anatomical outcomes of PPV in these patients. Material and Methods: This retrospective study reviewed the files of patients who underwent PPV for IOL dislocation into the vitreous in our clinic between January 2014 and December 2018. Patient age, gender, preoperative and postoperative best corrected visual acuity (BCVA), intraocular pressure (IOP), comorbid ocular pathologies, causes of IOL dislocation, time from IOL dislocation to PPV surgery, surgical methods, and preoperative and postoperative complications were recorded. Results: This study included 15 eyes of 15 patients with IOLs dislocated into the vitreous, of which 5 (33.3%) were female and 10 (66.7%) were male. Mean patient age was 60.8±22.67 (12-94) years. Seven (46.7%) of 15 eyes underwent a secondary IOL implantation in the same session as IOL extraction, whereas eight eyes were planned to undergo a secondary IOL implantation in a second session. Meanwhile, 2 (13.3%) eyes did not undergo IOL implantation. Median preoperative BCVA was 1.7 (0.4-1.92) logMAR and median postoperative BCVA was 0.5 (0-2) logMAR across all patients (p=0.002). After surgery, BCVA was higher in 12 patients (80%), unchanged in 2 patients (13.3%) and lower in one patient (6.7%). In our series, 3 eyes were detected to have preoperative RD and 2 eyes high IOP, whereas one patient showed recurrent RD and 4 eyes showed high IOP postoperatively. Median postoperative BCVA was significantly higher in patients who underwent secondary IOL implantation in a second session than those who underwent IOL implantation in the same session (p=0.035). Conclusion: PPV is a safe method for achieving successful visual and anatomical outcomes in patients with IOL dislocated into the vitreous cavity. In these patients, performing the secondary IOL implantation in a second session can result in a higher final visual acuity. Also, monitoring these complex cases closely is important in order to achieve better visual and anatomical outcomes. [ABSTRACT FROM AUTHOR]

Aim: To evaluate the anatomical and functional results in cases underwent 23-gauge pars plana vitrectomy (PPV) due to idiopathic stage 4 macular hole. Material and Methods: 17 eyes of 17 patients who underwent PPV due to idiopathic stage 4 macular hole between March 2013 and March 2016 at İnönü University Turgut Özal Medical Center Department of Ophthalmology were included in the study. The medical records of the patients were retrospectively reviewed. Macular hole staging was performed according to biomicroscopic examination and optical coherence tomography findings. Anatomical success was evaluated according to the condition of the macular hole after the surgery and functional success was evaluated according to the visual acuity. Results: 9 (53%) of the cases were females and 8 (47%) were males, the mean age was 66.6 ± 6.6 (55-81). PPV, internal limiting membrane (ILM) peeling and gas tamponade were applied to all cases. The mean follow-up period was 13.9±9.7 (4-30) months. ILM peeling was performed using trypan blue in three (17.6%) of the cases, brillant blue in 4 (23.5%) of the cases and membrane blue in 10 (58.8%) of the cases. Three cases (17.6%) were treated with C3F8 and 14 cases (82.3%) with SF6 gas tamponade. The mean preoperatively best-corrected visual acuity (BCVA) was 0.08±0.06 (0.03-0.2) and the mean postoperatively BCVA was 0.16±0.15 (0.03-0.5). Visual acuity did not change in two eyes (11.7%) and decreased in two eyes (11.7%). Macular hole had not closed in four patients (23.5%). Conclusion: 23 gauge PPV, ILM peeling and C3F8 or SF6 gas tamponade provides anatomical and functional success in the treatment of idiopathic stage 4 macular hole. [ABSTRACT FROM AUTHOR]

Aim: To evaluate the results of phacoemulsification (PE) surgery in completely monocular cases and to emphasize the important points in the pre-, intra- and post-operative periods. Material and Methods: A total of 42 patients who had no light perception in one eye and had underwent PE surgery in the other eye at our clinic between January 2014 and March 2016 were included in the study. The charts of the patients were evaluated retrospectively. The age and gender of the cases, whether there was an additional pathology in the eye undergoing surgery, the reason of visual loss in the other eye, the type of anesthesia used, pre- and post-operative best corrected visual acuity (BCVA) with the Snellen chart, intraocular pressure and intra- and post-operative complications were investigated. Results: There were17 (40.5%) female and 25 (59.5%) male patients with a mean age of 74.2±10.5 (45-93) years. The most common causes of the monocular state were glaucoma, cataract and trauma, the most common accompanying pathologies in the eyes undergoing cataract surgery were glaucoma, zonular weakness and age-related macular degeneration. Mean BCVA was 0.07±0.1 (0.01-0.4) pre-operatively and 0.5±0.3 (0.01-1) post-operatively (p=0.001). The mean follow-up duration was 3.9±5.6 months (1 week to 24 months). The most common post-operative complication was corneal edema. Conclusion: The stress created by cataract surgery on the physician and patient is quite high in monocular cases. However, satisfactory results with PE are obtained in these cases by carefully using pre-, intra- and post-operative methods. [ABSTRACT FROM AUTHOR]
