Management of cataract in keratoconus: early visual outcomes of different treatment modalities.

A review of 31 eyes with keratoconus who developed cataract and underwent phacoemulsification. Visual acuities were measured 1mo postoperatively. Six eyes with a history of good corrected distance visual acuity (CDVA) and a similar refractive and topographic astigmatic axis were implanted with toric intraocular lenses (IOLs).

Effect of phase-plate adjustment on retinal image sharpness and visible retinal area on ultrawide field imaging.

Background: To evaluate changes in image sharpness across ultrawide field (UWF) images and the effect of phase-plate adjustment on image contrast and extent of visible retinal area (VRA).

Methods: This was a single site evaluation of 200° UWF images acquired with phase-plate adjustment (California, Optos, plc) and without (200TX, Optos, plc). Images were acquired using standardized protocol.

Inducing fibrogenesis and new interfibrillary bonds in post-laser in situ keratomileusis keratectasia.

Flap creation weakens the cornea and is a risk factor for keratectasia after laser in situ keratomileusis (LASIK). We describe a new technique to halt the progression of keratectasia by mechanically reintegrating the flap into the residual stroma. Deep stromal vertical puncturing is performed in the 4.

EFFICACY OF INTRAVITREAL RANIBIZUMAB INJECTIONS IN THE TREATMENT OF VITREOUS HEMORRHAGE RELATED TO PROLIFERATIVE DIABETIC RETINOPATHY.

Purpose: To investigate the efficacy of intravitreal ranibizumab injections in proliferative diabetic retinopathy associated with vitreous hemorrhage (VH).

Methods: A prospective study including patients with proliferative diabetic retinopathy who presented with persistent VH. Vitreous hemorrhage was graded into mild, moderate, and severe.

Mathematical analysis of corneal remodelling after intracorneal ring surgery in keratoconus.

Aim: To represent mathematically the intersection between the ectatic corneal geometry and the plane of intracorneal ring implants (ICRS) in order to determine the corneal response to ICRS surgery in keratoconus (KC). Thereafter, to present the concept and early results of a newly derived topography-guided nomogram for ICRS surgery for the treatment of keratectasia.

Methods: The corneal rings plane intersection was modelled to a conic section.

Hemorrhage and/or Microaneurysm Severity and Count in Ultrawide Field Images and Early Treatment Diabetic Retinopathy Study Photography.

Objective: To evaluate detection of hemorrhage and/or microaneurysm (H/Ma) using ultrawide field (UWF) retinal imaging as compared with standard Early Treatment Diabetic Retinopathy Study (ETDRS) 7-field photographs (ETDRS photos).

Design: Single-site comparative study of UWF images and ETDRS photos.

Participants: One hundred twenty-six eyes of 69 patients with no diabetic retinopathy (DR) or mild or moderate nonproliferative DR (NPDR).

Evidence-Based Treatment of Diabetic Macular Edema.

Diabetes mellitus is a chronic disease that affects 415 million people worldwide. Despite treatment advances, diabetic eye disease remains a leading cause of vision loss worldwide. Diabetic macular edema (DME) is a common cause of vision loss in diabetic patients.

Evidence-Based Treatment of Diabetic Retinopathy.

Diabetic retinopathy (DR) is the most frequent microvascular complication from diabetes and requires annual screening and at least annual follow-up. A systemic approach to optimize blood glucose and blood pressure may halt progression to severe stages of DR and obviate the need for ocular treatment. Although there is evidence of benefit from fenofibrate or intravitreous antiVEGF treatment for eyes with nonproliferative DR (NPDR), these therapies are not standard care for NPDR at this time.

An Update on the Safety and Efficacy of Corneal Collagen Cross-Linking in Pediatric Keratoconus.

Keratoconus is a degenerative disease that affects adolescents and young adults and presents with variable thinning and conical deformation of the corneal apex. The resultant irregular astigmatism can progress to levels that can significantly affect everyday activities and overall quality of life. Therefore, stopping the progression of the disease is an essential part in managing patients with keratoconus.

Extensive superior limbic keratoconjunctivitis in Graves' disease: case report and mini-review of the literature.

Background: Superior limbic keratoconjunctivitis (SLK) is characterized as an inflammation of the superior bulbar conjunctiva with predominant involvement of the superior limbus and adjacent epithelial keratitis.

Methods: A 51-year-old woman, with a history of medically controlled Graves' disease was seen with an extensive SLK involving 5 mm of the superior cornea.

Results: Total remission was observed with topical steroids (DXM).

Photorefractive keratectomy in patients with mild to moderate stable keratoconus: a five-year prospective follow-up study.

Background: The purpose of this study was to evaluate the visual outcome of photorefractive keratectomy (PRK) in patients with mild to moderate stable keratoconus and to assess the risk of progression of the disease after the excimer laser procedure.

Methods: In this prospective study, carried out at the Clemenceau Medical Center, an affiliate of Johns Hopkins International, in Beirut, Lebanon, 119 eyes from 72 patients with grade 1-2 keratoconus (Amsler-Krumeich classification) underwent PRK. Forty-seven patients had both eyes treated and 25 patients had one eye treated.

Safety and visual outcome of Visian toric ICL implantation after corneal collagen cross-linking in keratoconus.

Purpose: To evaluate the safety and clinical outcome of phakic Visian toric implantable collamer lens (ICL) (STAAR Surgical, Monrovia, CA) insertion after corneal collagen cross-linking (CXL) in progressive keratoconus.

Methods: A retrospective study examined the results of the two-step CXL and Visian toric ICL implantation in 16 eyes of 10 patients with keratoconus. The two procedures were done at an interval of 6 months.

Azithromycin 1.5% ophthalmic solution: efficacy and treatment modalities in chronic blepharitis.
