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.

Delay in IOFB extraction, presence of intraocular hemorrhage, preoperative retinal detachment, primary surgical repair combined with IOFB removal are the predictive factors for anatomic failure.

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.

AimsTo evaluate the outcomes and complications of 23-gauge transconjunctival sutureless vitrectomy (TSV) with Silicone oil (SO) tamponade in complex vitreoretinal diseases.Settings and DesignEge university hospital ophthalmology department. Retrospective case series.Materials and MethodsForty eyes of 40 patients with diabetic tractional retinal detachment (DTRD) and proliferative vitreoretinopathy (PVR) were included in the study. Vitrectomy using 23-gauge system with SO endotamponade was performed. Peroperative and postoperative complications, anatomical and visual results were evaluated.Statistical analysis usedPaired Student's t-test.ResultsSimultaneous cataract surgery was performed in 17 eyes. Peroperative complications were posterior capsule rupture during phacoemulsification in one patient, vitreous and retinal incarceration in one patient. One eye required suture placement at the end of surgery due to SO leakage. Postoperatively, a small subconjunctival SO bubble in three patients, and hypotony in one patient (6 mmHg) were observed. Recurrent retinal detachment under SO occurred in one patient. Mean follow-up was 6.5 months (±2.7). Pre- and postoperative mean visual acuity was 2.22±0.91 logMAR and 1.11±0.8 logMAR, respectively (P<0.001). Mean intraocular pressure (IOP) on the first postoperative day was lower than preoperative IOP (11.3 ±3.2 versus 14.0 ±2.4 mmHg) (P<0.001).ConclusionsTwenty-three gauge instrumentation seems to be feasible, effective and safe for vitrectomy with SO injection in DTRD and PVR, and can be considered in the surgical management of these complex vitreoretinal diseases.

We aimed at evaluating the possible role of choroidal perfusion abnormalities in the development of choroidal neovascularisation (CNV) in patients with age-related macular degeneration (AMD). Twenty-six patients who had non-exudative AMD in the first eye and CNV secondary to AMD in the fellow eye were enrolled. Blood flow velocities, vessel pulsatilities and resistivities were measured from ophthalmic artery, nasal and temporal posterior ciliary arteries using colour Doppler imaging. Systolic and diastolic velocities were lower in eyes with CNV for all vessels, except for the systolic velocity of the nasal posterior ciliary artery (p >0.05). Pulsatility and resistivity indices were higher in eyes with CNV for all vessels. This difference was statistically significant for the resistivity index of the nasal and temporal posterior ciliary arteries (p = 0.032 and p = 0.021, respectively) and the pulsatility index of the nasal posterior ciliary artery (p = 0.035). We have shown that in patients with AMD choroidal blood flow is more impaired in the eyes with CNV than in the fellow eyes.
