Role of Radiation Therapy for Choroidal Hemangioma: A Brief Review |
Author : Kiran Turaka, Aruna Turaka* and Bobby N Koneru |
Abstract | Full Text |
Abstract :Choroidal hemangioma is an uncommon benign vascular hamartoma. Depending on the extent of the involved choroid, it can be subtyped into circumscribed form that occurs sporadically as an isolated tumor or a diffuse form that occurs in association with Sturge-Weber syndrome. It appears as an orange-red mass, located commonly posterior to the equator and is mostly asymptomatic. Poor vision is attributed to exudative retinal detachment, cystoid macular edema, foveal distortion and refractive errors. Diagnosis is crucial and is aided by ancillary tests such as ophthalmic ultrasonography, fundus fluorescein angiogram and Indocyanine green angiogram. The aim of treatment is to induce tumor atrophy, resolve the exudates, improve the vision, preserve the overlying retinal function and salvage the globe. Symptomatic tumors are treated by various treatment methods such as laser photocoagulation, transpupillary thermotherapy, photodynamic therapy and radiation therapy. Though external beam radiotherapy is a safe and effective treatment method, radiation induced complications limited its utility. Advanced radiation delivery techniques (such as proton beam therapy, plaque brachytherapy and stereotactic radiosurgery with Gamma Knife Radiosurgery) precisely target the tumor without damaging surrounding ocular tissues. These focal treatment methods enhance both in regressing the tumor, resolve the subretinal fluid/exudates thereby re-attaching retina and preserve or stabilize the visual acuity. The radiation induced ocular side effects are less with these newer radiation delivery methods. Anti-vascular endothelial growth factors and oral ß-blockers are newer treatment methods available for treating choroidal hemangiomas. |

Abstract | Full Text |
Abstract :Background: Diabetic retinopathy, the most common retinal vascular disease, is the leading cause of new-blindness in adults during the third through sixth decades of life.
Purpose: To determine the correlation between central macular thickness (CMT) and both HbA1c and fasting serum lipids level in early stage non proliferative diabetic retinopathy.
Results: The patients were divided into two groups as HbA1c >8.67% (Group I, n: 60) and HbA1c =8.67% (Group II, n: 72). The mean CMT of better eyes was 273.28±34.61 µm. The mean CMT of worse eye was 304.40±64.31 µm. According to comparison between Group I (HbA1c >8.67%) and Group II (HbA1c =8.67%) the mean CMT’s were not different in two groups (P: 0.37). |

Cuban Ocular Toxoplasmosis Epidemiology Study (COTES): Clinical Features in 279 Patients from Central Cuba |
Author : J Daniel Diaz*, Jorge L Bustillo, Idarmes C Pacheco and David C Gritz |
Abstract | Full Text |
Abstract :Purpose: To characterize the clinical features of ocular toxoplasmosis (OT) in Central Cuba.
Methods: A database at a large regional referral center was searched for patients who, from April 1, 2011 to May 31, 2013, had the potential diagnosis of OT. Inclusion criteria were the clinical diagnosis of OT, characterized by focal retinochoroidal inflammation. Medical records were reviewed to confirm inclusion criteria (visual acuity recorded in decimal form). |

Anterior Chamber Foldable Phakic Intra Ocular Lens Safety and Efficacy |
Author : AlAhmady Hamad AlSammans*, Ashraf Mostafa Moahammed and Usama Ali Mohammed |
Abstract | Full Text |
Abstract :Purpose: Correction of myopia by implantation of intra ocular lens is a growing surgery. In this study I am trying to assess the visual outcome stability and safety of eyes undergoing Anterior chamber foldable phakic lens implantation (Artiflex) (Ophtec BV, Groningen, The Netherlands) or (veriflex) (AMO,Santa Ana,CA) for myopia unsuitable for LASIK and detection of early and late complications along three years follow up period. |

Atypical Presentation of Uveal and Conjunctival Melanoma in the Anterior Segment |
Author : Alina Djougarian*, I Rand Rodgers and Alan H Friedman |
Abstract | Full Text |
Abstract :Ocular melanoma is a rare malignancy arising from melanocytes of the uvea, the conjunctiva, and the orbit. Uveal melanoma is the most common intraocular malignancy in adults, accounting for 85-95% of ocular melanomas [1-3]. The conjunctival form accounts for 5% of ocular melanomas. Uveal and conjunctival melanoma are very distinct from each other biologically. We describe a case of conjunctival melanoma and a uveal melanoma both presenting as large masses of the anterior segment. |
