Objectives: To compare anterior chamber depth (ACD) changes after phacoemulsification surgery in patients with pseudoexfoliation syndrome (PEX) and normal patients using an anterior segment imaging method. Another aim of this study was to evaluate the effect of these changes on the accuracy of intraocular lens (IOL) power calculation and postoperative refraction.Materials and Methods: Twenty-two eyes of 22 patients with PEX and 30 eyes of 30 normal patients who underwent uneventful phacoemulsification surgery and IOL implantation were included in the study. The ACD of all patients was evaluated preoperatively and at 3 months postoperatively with the ALLEGRO Oculyzer (WaveLight® Oculyzer™ II, Alcon, Novartis)-Scheimpflug imaging system.Results: The postoperative mean ACD values were significantly larger than the preoperative ACD values in both groups (p<0.001 for both groups). The pre- to postoperative change in ACD was 0.46±0.3 mm in the PEX group, which was a larger change than seen in the normal patients (0.12±0.1 mm) (p=0.04). The mean absolute errors (MAE) calculated with different IOL formulas (SRK/T, Haigis, Hoffer and Holladay 1 formulas) were comparable and no statistically significant difference was observed between the two groups (p=0.21).Conclusion: Phacoemulsification induces more significant ACD changes in patients with PEX compared to normal patients. However, the MAE did not differ significantly between the groups.

Purpose: To evaluate the macular microvascular changes in patients with intermediate uveitis (IU) using optical coherence tomography angiography (OCT-A) and to determine the relationship of OCT-A measurements with disease duration and activity. Methods: This cross-sectional study was performed at the uvea department of a tertiary hospital. Patients with IU (8 women, 8 men; mean age: 28.80 ± 12.80 years) were included in the study. The macular thickness measurements obtained by optical coherence tomography (OCT) (Heidelberg Spectralis, Heidelberg Engineering, Heidelberg, Germany) and macular superficial and deep vessel density (VD) parameters obtained by OCT-A (Avanti RTVue-XR; Optovue, Fremont, CA, USA) were compared with healthy subjects (12 men, 22 women; mean age: 28.40 ± 8.32 years). Eyes with pathology including marked obvious edema in the macula were not included in the study. Results: The macular thickness was found to be higher in the patient group ( p < 0.001). The deep and superficial VD measurements in almost all quadrants in both superficial and deep layers were significantly lower in the IU patient group ( p < 0.05). Macular thickness was increased in the active state of IU ( p = 0.03), however, none of the OCT-A parameters showed a significant difference between active and inactive IU patients ( p > 0.05). No correlation was observed between OCT-A parameters and total IU disease duration. Conclusion: Quantitative analyses of macular vascular structures demonstrate significantly reduced VD in both superficial and deep retinal layers in IU patients. Considering the importance of the macula in visual prognosis, OCT-A can provide crucial data for the monitoring and follow-up of IU patients.

No clinical difference is noted between Colorado needle and scalpel incisions in terms of ecchymosis and scar cosmesis after aesthetic blepharoplasty.

A 6-year-old boy with a complaint of blurred vision for two months was referred to our clinic. His visual acuity was 20/32 in the right eye and 20/20 in the left eye. Optical coherence tomography (OCT) revealed optic disc pit maculopathy in the right eye. The patient was followed for 6 months without any treatment. At the end of the 6-month period, the patient’s visual acuity was 20/20 in both eyes. The OCT imaging showed spontaneous regression of the optic disc pit maculopathy. In this case report, it is concluded that in children, spontaneous regression of the optic pit maculopathy with full recovery of visual acuity is possible. The development of optic pit maculopathy in childhood is rare and there are not enough studies on the treatment methods. Therefore, our case report may be helpful in the management of similar cases of pediatric optic disc maculopathy.
