PURPOSE: To investigate safety of accelerated corneal crosslinking during the first postoperative month. METHODS: In this retrospective study, 76 eyes of 60 patients with verified progressive keratectasia were enrolled in this study and followed for 1 month after accelerated CXL (18 mW/cm2 for 5 min, radiant exposure 5.4 J/cm2 ) (A-CXL(5*18)). Preoperatively, objective refraction, slit lamp inspection, and corneal tomography were performed. Early postoperative slit lamp examinations were performed on days 1 and 4...

BACKGROUND: To evaluate rotation and its influencing factors of an aspheric one-piece hydrophobic acrylic intraocular lens (IOL) Vivinex XY1 during 6 months after operation. METHODS: In this institutional trial, 122 eyes of 66 patients were implanted with a non-toric aspheric IOL Vivinex XY1 (Hoya Corporation, Tokyo, Japan). IOL alignment was assessed at the end of surgery, 1 hour, 1 week, 1 month and 6 months after implantation. Confounding factors such as axial length, presence of anterior fibrosis and randomised implantation in four different intended axes (0°, 45°, 90°, 135°) were evaluated...

PURPOSE: Evaluate whether there are significant changes in choroidal thickness following trabeculectomy, and how they relate do the decline in intraocular pressure. METHODS: This was a prospective evaluation of 28 eyes who underwent Moorfields modified trabeculectomy. The choroidal thickness was measured via OCT with enhanced depth imaging, before surgery and 1 day, 1 week and 1 month after surgery. Measurements were taken at the fovea, 1000 µm temporal to the fovea and 1000 µm nasal to the fovea...

PURPOSE: The assessment of corneal biomechanics is essential for studying ophthalmological operations, such as refractive surgeries, and for more accurate estimation of intraocular pressure. The chief aim of the current study is to characterize corneal and fatty tissues in order to construct a model to predict eye globe behavior during dynamic tonometry tests. METHODS: In the present study, images from corneal deformation, acquired from Corvis ST tonometer, were processed...

Background: Lid margin asymmetry and its associated compensatory mechanisms might cause patients to seek treatment to improve aesthetics. Surgery might not be indicated and can potentially worsen the asymmetry in these cases. Methods: A case series of three patients was organized to illustrate the use of botulinum toxin administered to the pre-tarsal orbicularis for the correction of micro-ptosis and improved symmetry. The marginal reflex distance and tarsal platform show were measured on both sides. Measurements were made using ImageJ software on standardized frontal photographs taken pre- and post-injection...

Intraparenchymal meningiomas are very rare: only 26 cases have been diagnosed in patients younger than 20 years since 1954. They can lead to preoperative differential diagnosis mistakes due to their atypical neuroimaging appearance. A multimodal approach is thus necessary to plan a surgical procedure aiming to receive the best extent of resection while preserving the patient's functional integrity. The authors report the case of a 7-year-old boy with a history of blurred vision, left eye deviation, and weakness on the left side of his body...

REVIEW
Argyrios Chronopoulos, Jong Min Ong, Gabriele Thumann, James S Schutz
Occult globe rupture is a traumatic dehiscence of the sclera at or posterior to the rectus muscle insertions without a visible eye wall defect on slit lamp examination. Occult scleral ruptures are important because they can be difficult to diagnose, but normally require preoperative protection against external pressure to reduce risk of herniation of ocular contents through the rupture and then urgent surgical repair to restore eye wall structural integrity and achieve optimum prognosis. A deeper than normal anterior chamber with posteriorly retracted plateau iris seen immediately after acute ocular trauma is virtually pathognomonic of posterior globe dehiscence...

Background: To report two cases of rhegmatogenous retinal detachment (RRD) associated with asteroid hyalosis (AH). Case Presentation: Two patients presented with RRD originating from a flap tear. Case 1 involved a 62-year-old male who was found to have bullous RRD in his left eye originating from a flap tear. During vitreous surgery, a thick vitreous cortex was found to have strongly adhered to the entire retinal surface, from the center to the periphery. A bimanual method was then used in conjunction with the vitrectomy to create an artificial posterior vitreous detachment...
