PURPOSE: Diabetic retinopathy (DR) is one of the leading causes of blindness worldwide. Accurate investigative tools are essential for the early diagnosis and monitoring of the disease. Optical coherence tomography angiography (OCTA) is a recently developed technology that enables visualisation of the retinal microvasculature. METHODS: A systematic review of the literature was performed to examine the diagnostic use of OCTA in DR to date. Medline, EMBASE, and Cochrane databases were searched to find relevant studies...

PURPOSE: To determine the distribution of anterior chamber depth (ACD), anterior chamber volume (ACV), and anterior chamber angle (ACA) values in a rural population over 5 years of age using the Pentacam. METHODS: In this cross-sectional study, samples were selected from over 1-year-old inhabitants of two villages in Iran using a multistage cluster sampling approach. All participants underwent the measurement of uncorrected and corrected visual acuity and auto-refraction, retinoscopy, subjective refraction, and slit lamp examination...

PURPOSE: The purpose of this study was to investigate the thermal injuries caused by ultrasonic pars plana phacoemulsification and aspiration (PPPEA) using pig eyes. METHOD: Using a 20-gauge (G) vitrectomy system (Accurus® , Fragmatome; Alcon Laboratories) in both the 'open-tip' and 'closed-tip' techniques, PPPEA was performed in pig eyes and the subsequent thermal injuries generated around the scleral wound were measured by infrared thermal imaging (thermography)...

PURPOSE: To investigate the serial choroidal volume change following orbital blow-out fracture (BOF) repair. METHODS: The choroidal volume was measured by optical coherence tomography in patients who underwent BOF repair, preoperatively and postoperatively at 1, 4, 12 and 24 weeks. The orbital volume ratio (OVR) was obtained by dividing the orbital volume of the traumatized orbit by that of the contralateral side using three-dimensional computed tomography imaging...

PURPOSE: To study the connective tissue (CT) structure of upper eyelid skin of primary open-angle glaucoma (POAG) patients. PATIENTS AND METHODS: Forty-seven patients aged 47-91 expecting blepharoplasty formed 3 groups: group 1 [16 subjects without POAG, median age 55 years (interquartile range 54-55.5)], group 2 [12 subjects without POAG, median age 73 (72-76.5)], and group 3 [(19 subjects with POAG, median age 74 (70-80.5)]. Age differences between groups 1 and 2 and groups 1 and 3 are significant (p < 0...

PURPOSE: To summarize proposed causative factors and the outcomes of surgical practices for involutional lower eyelid entropion. METHODS: We reviewed the literature on proposed causative factors and the outcomes of surgical practices for involutional lower eyelid entropion, searched on PubMed. RESULTS: Vertical and horizontal laxities of the lower eyelid, and overriding of the preseptal orbicularis oculi muscle onto the pretarsal orbicularis oculi muscle have been proposed as the major causes of involutional lower eyelid entropion...

PURPOSE: To present multimodal imaging of multifocal chorioretinitis secondary to endogenous candida infection in a young adult. METHODS: A 49-year-old woman who presented for evaluation of bilateral endogenous candida chorioretinitis underwent complete ophthalmic examination, in addition to fundus photography (FP), enhanced depth imaging optical coherence tomography, fundus autofluorescence (FAF), fluorescein angiography (FA), indocyanine green angiography (ICGA) and optical coherence tomography angiography (OCTA)...

PURPOSE: We aimed to investigate that change of IPI values after sedation of patients undergoing cataract surgery under sedation. METHODS: We included 50 patients (ASA I-III) undergoing cataract surgery under sedation by phacoemulsification method in this prospective observational study. IPI, SpO2 , ETCO2 , respiratory rate (RR), peripheral pulse rate (PR), hemodynamic data and BIS values and perioperative complications were recorded. RESULTS: Compared to baseline values, RR value at 5th min, RR, PR, IPI values at 10th min and RR, PR values at 15th min were significantly low and heart rate value at 15th min and arterial pressure, bispectral index (BIS) values at 5th min, 10th min, 15th min, 20th min, 25th min and 30th min were lower than baseline values...

PURPOSE: To compare postoperative outcomes of 27-gauge (G) and 25-G vitrectomy conducted as day surgery for proliferative diabetic retinopathy (PDR). METHODS: One hundred eighty-five consecutive PDR patients (185 eyes) who underwent primary vitrectomy (27-G in 64 eyes, 25-G in 121 eyes) were analyzed. RESULTS: The 27-G and 25-G groups did not differ significantly in preoperative Early Treatment Diabetic Retinopathy Study (ETDRS) score, age, or preoperative intraocular pressure...

PURPOSE: To explore a measuring method for retinal sensitivity in macular hole area by Microperimeter-3 (MP-3) and evaluate its predictive value on visual prognosis. METHODS: This was a case series study including 44 eyes of 44 patients with idiopathic macular hole. Retinal sensitivity inside and 0.5 degree outside the macular hole margin was measured, and its mean value was defined as macular hole sensitivity (MHS). Best-corrected visual acuity (BCVA), minimum diameter of macular hole (MD), IS/OS defect diameter, retinal sensitivity in 8 degrees and 2 degrees were also recorded preoperatively and 4 months after operation...
