PURPOSE: A meta-analysis was performed to evaluate the safety and efficacy of topical 3% diquafosol in treating patients with dry eye disease (DED). METHODS: Nine qualified randomized controlled trials incorporating 1,467 patients were included. Two of the reviewers selected the studies and independently assessed the risk of bias. The outcome measures were Schirmer score, tear film break-up time (TFBUT), rose bengal staining score, and corneal fluorescein staining score...

Lamellar macular hole (LMH) is a vitreoretinal disorder characterized by an irregular foveal contour, a break in the inner fovea, dehiscence of the inner foveal retina from the outer retina, and the absence of a full-thickness foveal defect with intact foveal photoreceptors. The pathogenesis is only partially known. The advent of high-resolution optical coherence tomography has allowed distinguishing between two types of epiretinal membrane (ERM) associated with LMH: a conventional ERM (commonly found in macular pucker) and an atypical ERM (known by varied names: dense, epiretinal proliferation, or degenerative)...

BACKGROUND: Digital retinal imaging is the gold standard technique for diabetic retinopathy (DR) and diabetic macular oedema (DME) assessment during DR screening. OBJECTIVES: To evaluate the diagnostic accuracy of digital retinal fundus image (DRFI) analysis in detecting DME using three manual grading systems (MGS) and comparing it with optical coherence tomography (OCT) findings. METHOD: A total of 287 DRFI of 287 eyes were analysed. Non-stereoscopic 45° images were acquired using a Kowa VX-20 camera and were graded according to three MGS: Early Treatment Diabetic Retinopathy Study (ETDRS), International Clinical Diabetic Retinopathy (ICDR), and United Kingdom National Screening Committee (UKNSC)...

PURPOSE: To evaluate the efficacy of bilateral lateral rectus muscle recession (BLR) to treat recurrent exotropia after bilateral medial rectus muscle resection (BMR). METHODS: Twenty-four patients who underwent BLR for recurrent exotropia and were followed up for more than 6 months were included in this retrospective study. All of them had prior BMR. The angle of deviation, success rates, near stereopsis, and surgical effect of BLR were evaluated. Surgical success was defined as postoperative deviations ≤10 prism diopters (PD)...

Retinal angiomas are rare tumors that develop within the vascular bed of the retina. Their occurrence may be sporadic or as part of the multisystem disorder called von Hippel-Lindau disease. It is well established in literature that retinal angiomas have a natural history of evolving as small aneurysmal dilatations and progressing to vision-threatening retinal detachments. Several approaches to the management of these angiomas have been reported in the literature, but it is difficult to decipher which modality is best suited for which type of angioma...

PURPOSE: To evaluate pars plana vitrectomy (PPV) outcomes in cases with tractional diabetic macular edema (tDME). METHODS: We conducted a single-center retrospective study with a follow-up of 12 months. Forty-six eyes with tDME of 38 patients submitted to PPV between 2013 and 2015 were assessed. A standard PPV was performed and surgical outcomes were registered at the 3-, 6-, and 12-month follow-up. RESULTS: The baseline median best corrected visual acuity (BCVA) in ETDRS (Early Treatment Diabetic Retinopathy Study) letters and the median central foveal thickness (CFT) were 43...

The use of corneal tissue for ex vivo therapeutic evaluations is limited due to its rapid loss of viability after excision. Optimization of storage conditions may allow prolonged retention of physical tissue properties. In this study, we evaluated how storage in optimized organ culture (OC) medium at 37°C or phosphate-buffered saline (PBS) at 2-8°C impacted physical properties of bovine corneas. Tissue hydration, permeability and histology were monitored at baseline and following 1, 4 and 7 days of storage...

PURPOSE: To assess the progression of diabetic hard exudates over an 8-week period, using a high-resolution adaptive optics camera. DESIGN: Prospective observational study. METHODS: Five eyes of three patients presenting diabetic maculopathy with hard exudates were studied. An area of clinically visible exudates was imaged sequentially using SD-OCT and high-resolution flood illumination adaptive optics for 2 months, on a weekly basis. A time-lapse video was obtained for each eye studied...

PURPOSE: The aim of this paper was to investigate the degree of inflammation and dry-eye disease (DED) in recurrent pterygium. METHODS: Fifty-five patients with a history of pterygium excision were divided into 3 groups - Group 1: no recurrence after the first excision; Group 2: recurrence after the first excision; Group 3: no recurrence after the second excision. Dry-eye symptoms and tear production were elicited for each patient. RESULTS: A high prevalence of DED was observed in patients with primary and recurrent pterygium based on self-reported dry-eye symptoms (63...

PURPOSE: To study the structural and functional changes of retinal ischemia and investigate their association with macular edema (ME) or microaneurysm (MA) formation in eyes with retinal vein occlusion (RVO). METHODS: Sixty eyes of 30 patients (27 eyes with branch [b]RVO, 3 with central RVO, and 30 fellow eyes) were retrospectively reviewed. Optical coherence tomography (OCT), OCT angiography (OCTA), and microperimetry were performed simultaneously to measure retinal thickness and sensitivity...

AIMS: To conduct a systematic review and meta-analysis of retinopathy prevalence in patients with type 1 diabetes (T1D) in 22 Arab countries. METHODS: We systematically searched 4 different literature databases (PubMed, Science Direct, Web of Science and Embase), from the date of inception until December 2017, to collect all the information about patients with T1D who developed retinopathy complications; for statistical analysis, we used MetaXL to evaluate the pooled prevalence estimate and the subgroup prevalence estimates employing double arcsine transformation and inverse variance heterogeneity models...

PURPOSE: To evaluate papillary, peripapillary, and macular vasculature with optical coherence tomography angiography in preperimetric (PPG), primary open-angle glaucoma (POAG), and normal eyes, and to assess diagnostic ability and associations among the vasculature and structural damage. METHODS: This was an observational, cross-sectional study. Retinal nerve fiber layer (RNFL), ganglion cell complex thickness, whole-image (wiVD), inside disc (idVD), peripapillary (ppVD), and macular vessel densities were obtained...

AIM: To establish a novel retinal angiography method, red-free angiography (RFA), to investigate retinal changes in age-related macular degeneration (AMD) and polypoidal choroidal vasculopathy (PCV). METHODS: Following the venous phase of fundus fluorescein angiography (FFA), the detection mode was switched to red-free reflectance to acquire RFA images using the same parameters. RESULTS: RFA showed subretinal fluid, polyps, and outer retinal tubulation, with a higher definition than the FFA and red-free reflectance results...

PURPOSE: Surgical or diagnostic procedures are often accompanied by a short-term increase in intraocular pressure (IOP). A short-term increase in IOP can occur during refractive procedures, vitreoretinal surgery, transillumination, photocoagulation, or cryocoagulation. A porcine eye model was chosen (n = 89) to compile comparable study data and to de termine correlations between the force induced and the resulting intraocular pressure while excluding the effect of surgeons. METHODS: The IOP was measured in the anterior chamber...

PURPOSE: To investigate dynamic changes in aqueous humor levels of vascular endothelial growth factor (VEGF), placental growth factor (PlGF), and inflammatory factors in patients receiving intravitreal ranibizumab injection (IRI) or intravitreal aflibercept injection (IAI) to treat central retinal vein occlusion (CRVO) with macular edema. METHODS: In 22 CRVO patients scheduled to receive 3 doses of ranibizumab (11 eyes) or aflibercept (11 eyes) at monthly intervals, aqueous samples were collected at the time of intravitreal injection...
