PURPOSE: To assess the surgical and functional outcome of internal direct cyclopexy as therapy of complicated traumatic cyclodialysis. METHODS: The single-centre interventional case-series study included eyes with traumatic cyclodialysis who had consecutively been treated. Internal cyclopexy was performed using double-armed sutures introduced into the eye through the pars plana opposite to the cyclodialysis cleft and which were laid parallel to limbus. Additional procedures included cataract surgery, and pars plana vitrectomy...

INTRODUCTION: Presbyopia is the most prevalent refractive error. With a progressive aging population, its surgical correction is an important challenge for the ophthalmology community, as well as the millions of patients who suffer from it, and who are increasingly demanding alternatives to its correction with glasses or contact lenses. MATERIAL AND METHODS: A review is presented with a synthesised discussion on the pathophysiological theories of presbyopia and an updated and analytical description of the non-lens involvement surgical techniques used to treat presbyopia...

PURPOSE: To compare releasable and regular sutures in combined angle and filtering surgery for primary congenital glaucoma. METHODS: A prospective study was conducted on 39 eyes (26 right eyes) of 39 children (20 boys; 19 girls) who had primary congenital glaucoma treated with combined trabeculotomy-trabeculectomy with mitomycin C and scleral flap closure with regular or releasable sutures. Follow-up was 24 months. Success rates (defined as an intraocular pressure [IOP] < 16 mm Hg without hypotony-related complications and/or lack of IOP-related progression of the disease) were studied and complications were noted...

Lorenzo J Cervantes
A slight modification to the Yamane transconjunctival double-needle flanged-haptic technique of intrascleral fixation of an intraocular lens (IOL) shows the technique's usefulness when combined with Descemet-stripping endothelial keratoplasty (DSEK). The modification uses bipolar cautery to create flanges at the tip of the IOL haptics and delays tucking the haptics into the scleral tunnels until DSEK has been completed. Bipolar cautery enables the technique to be used in situations in which disposable low- or high-temperature cautery, as originally described, might not be possible...

It is generally accepted that myopic defocus is a more potent signal to the emmetropization system than hyperopic defocus: one hour per day of myopic defocus cancels out 11 h of hyperopic defocus. However, we have recently shown that the potency of brief episodes of myopic defocus at inhibiting eye growth depends on the time of day of exposure. We here ask if this will also be true of the responses to brief periods of hyperopic defocus: may integration of the signal depend on time of day? If so, are the rhythms in axial length and choroidal thickness altered? Hyperopic defocus: Birds had one eye exposed to hyperopic defocus by the wearing of -10D lenses for 2 or 6 h at one of 3 times of day for 5 days: Morning (7 a...

PURPOSE: To assess whether short-term soft contact lens wear alters the anterior eye surface. METHODS: Twenty-two neophyte subjects wore soft contact lenses for a period of five hours. Topography based corneo-scleral limbal radius estimates were derived from height measurements acquired with a corneo-scleral profilometer. Additionally, central corneal thickness (CCT), anterior chamber depth (ACD), corneal curvature radius (R) and white-to-white (WTW) diameter were acquired with an OCT-assisted biometer...

INTRODUCTION: Corneal burn grade IV usually leads to blindness. Several different surgical techniques remain challenging owing to the extensive tissue damage. Here, we introduce a novel technique with a 15 mm corneoscleral and limbal homologous graft combined with sequential autologous corneal removal ab interno, with a vitrectomy probe to save the anterior chamber angle. In vivo anatomy with optical coherence tomography is the surgical key. METHOD: A large 15 mm sclerocorneal graft is sutured on top of the remainder of the destroyed cornea and sclera after removal of the epithelium and conjunctiva, with anterior synechiolysis if necessary, peripheral iridectomy and conjunctivoplasty...

This is a prospective clinical assay that included six patients who were diagnosed with penetrating corneal injury, traumatic cataract, and posterior segment intraocular foreign body (IOFB). Following anterior segment repair and extraction of traumatic cataract by clear cornea phacoemulsification, a standard 25-gauge transconjunctival pars plana vitrectomy was performed to find and release the IOFB. With active suction using a 25-gauge silicone tipped cannula, the foreign body was retrieved and safely placed in the anterior chamber...

This study aims to report the use of mini-scleral contact lens in the management of mucous membrane pemphigoid (MMP) with persistent epithelial defects. A 68-year-old male with a history of ocular pain and declining visual acuity was referred to our clinic with a diagnosis of MMP. His corrected distance visual acuity (CDVA) was 20/200 in the right eye and 20/100 in the left eye. Despite being on lubricants, topical steroids and intravenous cyclophosphamide, the patient developed persistent corneal epithelial defects in both eyes...

INTRODUCTION: The best method of aphakia correction is in the bag implantation of Posterior Chamber Intraocular Lens (PCIOL). When this ideal procedure is not possible due to lack of integrity of posterior capsule or zonules, the other alternatives are broadly categorized into two: extraocular and intraocular. Whereas, the former includes contact lenses and aphakic glasses, the latter ones are further divided into anterior and posterior chamber methods. Anterior Chamber Intraocular Lenses (ACIOL) can be with or without iris claw...

REVIEW
Daddi Fadel
The evolution of scleral lenses has led to new formulations of scleral fitting concepts and designs. The diameters of modern scleral lenses have been overhauled too and they are smaller comparing to the original ones. Nowadays, prescription of mini-sclerals supposedly seems in major extension and it appears indeed the necessity of some practitioner to differentiate the smaller mini-scleral lenses from larger mini-scleral lenses empathizing that they are the "smaller" ones. Therefore, it is maybe, necessary a definition of mini-scleral lenses referring to the landing zone width in relation to the horizontal visible iris diameter (HVID) and the limbus extension...

PURPOSE: The purpose of this study was to determine the change in over-refraction, if any, after a scleral lens settled on the eye for 6-8 h. METHODS: Sixteen patients of varying refractive errors and normal corneal curvatures (measured with Pentacam(™) Oculus) were fitted with trial Mini-Scleral Design (MSD) scleral lenses (15.8 mm diameter) in one eye. The sagittal depths of the scleral lenses were selected by adding 350 μm to the corneal sagittal heights measured at a chord length of 15 mm with the Visante(™) optical coherence tomographer (OCT) anterior segment scans and picking the closest available trial lens in the set...

Migration of intraocular silicone oil, used in the treatment of complicated retinal detachment, has been rarely described, but when it happens it can arise with a differential diagnosis with scleral buckling extrusion, tumor, dermoid, ocular cysticercosis, and abscess. The presence of silicone oil in the eye gives very ugly echographic pictures, but these kinds of pictures can be very useful in making a differential diagnosis in the above-mentioned cases. A 39-year-old white female complained of the presence of conjunctival hyperemia and tearing in the right eye (RE); her visual acuity was hand motion, and the intraocular pressure was 14 mmHg...
