We determined the incidence and causes of clinical and angiographic cystoid macular edema (CME) after uncomplicated phacoemulsification and intraocular lens implantation in otherwise normal eyes. This study comprised 252 eyes of 252 patients who had uncomplicated phacoemulsification with continuous curvilinear capsulorhexis and in-the-bag acrylic intraocular lens implantation. The presence of clinical and angiographic CME was evaluated 45 days after surgery, using fundus fluorescein angiography. Age, sex, cataract type, iris color, and real phacoemulsification time of the patients were also recorded. The mean age of the patients was 69.86 (range 60–82) years). Clinical CME was not detected in any eye at any postoperative visit. There were 23 cases with angiographic CME (9.1%). There were no significant differences between the groups who were later found to be angiographically CME-positive or CME-negative in any variable recorded (p >0.05). The incidences of clinical and angiographic CME after uncomplicated phacoemulsification were 0 and 9.1%, respectively. These results indicate that the occurrence of clinical CME has greatly reduced after uncomplicated phacoemulsification operations, but the incidence of angiographic CME is still nearly equal to the incidence of the extracapsular technique.

Malposition of an intraocular lens (IOL) may cause symptoms such as glare, halos, and other visual aberrations. The purpose of this study is to determine the effect of two different anterior capsulotomy techniques on IOL tilt and decentration. Bag-fixated IOL implantation after uncomplicated extracapsular cataract extraction was performed using both envelope (65 eyes) and continuous circular capsulorhexis (CCC) technique (42 eyes). Eyes were followed-up at least 6 months postoperatively. While the mean IOL decentration after envelope technique was found to be 0.65 mm, this was 0.15 mm after CCC technique. On the other hand, the mean actual tilting angle of IOL after envelope technique was 5.66 degrees, whereas this was 1.13 degrees after CCC technique. The aforementioned differences were statistically significant (p < 0.01, and p < 0.01). Furthermore, in 17 eyes (26.1%) where envelope technique and in 29 (69.0%) eyes where CCC technique was used demonstrated no IOL tilt and decentration. This study shows that the CCC technique may result in less optical problems due to IOL malposition compared to the envelope technique.

Grade C(1) PVR and multiple breaks were found to be significant risk factors for anatomic failure in rhegmatogenous RD treated by conventional buckling surgery.

Both surgical procedures can achieve favorable and comparable anatomic outcomes in the majority of patients in the treatment of RD with multiple breaks. Intra-and postoperative complications are different in the two procedures.

Vitreoretinal interface changes and vitreoretinal separations and progression of separation can be easily evaluated by OCT. The current study confirms that posterior vitreous detachment occurs commonly soon after cataract surgery.

Objective: To present the etiological factors of patients with Retinal Vein Occlusion (RVO) under the age of 50 years. Methods: The study was conducted at Ege University Medicine Faculty Department of Ophthalmology. The clinical records of patients with RVO under the age of 50 seen between January 2014 and March 2018 were analyzed retrospectively. Forty patients comprised the study. Detailed ophthalmologic examination was performed. Past medical history, drug use, thrombophilic features, hyperviscosity syndromes and pathologies that may cause vasculitis were noted. Results: Forty patients, 22 (55%) male and 18 (45%) female, were included. Mean age was 41.6 ± 10.01 years. Mean intraocular pressure and best-corrected visual acuity were 16.8 ± 5.47mmHg and 0.76 ± 0.64 logMAR, respectively. Hyperhomocystenemia (15 patients, 37.5%), Behçet’s disease (three patients, 7.5%), diabetes and/or hypertension (16 patients, 40%), methylenetetrahydrofolate reductase gene mutation (11 patients, 27.5%), prothrombin gene mutation (four patients, 10%) and factor V Leiden mutation (five patients, 12.5%) were present among the patients as etiological factor. Multiple etiological factors were detected in 11 (27.5%) patients. Factor V Leiden mutation and methylenetetrahydrofolate reductase gene mutation were detected in one patient (2.5%) with Behçet’s disease. Four patients with diabetes and/or hypertension also had hyperhomocystenemia and one of them had additionally prothrombin gene mutation. Two patients with methylenetetrahydrofolate reductase gene mutation also had a factor V Leiden mutation and one of them had additionally a prothrombin gene mutation. Three patients with methylenetetrahydrofolate reductase gene mutation also had hyperhomocystenemia and one patient with prothrombin gene mutation also had methylenetetrahydrofolate reductase gene mutation. Conclusions: Etiological factors that might result in RVO in young individuals should be investigated in detail. Targeted therapies may help to prevent development of new RVOs and potential vascular problems in other organs. doi: https://doi.org/10.12669/pjms.35.5.546 How to cite this:Nalcaci S, Degirmenci C, Akkin C, Mentes J.
