PURPOSE The purpose of this study was to report a case of Von Hippel-Lindau disease (VHL) with twin retinal capillary hemangiomas that was successfully treated by vitreous surgery for tractional retinal detachment following laser photocoagulation. CASE A 44-year-old male presented at our university hospital after noticing decreased visual acuity in his right eye. The patient had previously un...

PURPOSE: To better define the effect of laser in situ keratomileusis (LASIK) on myopic eyes and the risk and incidence of retinal complications after surgery.METHODS: In a prospective study, 200 eyes of 100 patients, 49 male and 51 female, with a mean age of 29.7 years, had a complete posterior pole examination before and at 1 week, 1, 3 and 12 months after bilateral simultaneous LASIK for the ...

Laser applications have been increasingly successful in many fields of medicine and may soon occupy an important position in medical therapeutics. In ophthalmology, where the unique non-scattering optical properties of the eye allow for tight focusing of laser light, the conditions of retinal detachment, retinal bleeding, and diabetic neovascularization are routinely treated with lasers. Nevert...

come clinically visible, resulting in the blue appearance of the sclera. We report the treatment of rhegmatogenous retinal detachment in 4 eyes of 3 patients with OI. Scleral buckling surgery, pneumatic retinopexy, and primary vitrectomy are the standards for repair of uncomplicated rhegmatogenous retinal detachments. In patients with OI, however, the thin sclera provides an increased risk of s...

Subretinal neovascular membranes (SRNM) are a deleterious complication of laser eye injury and retinal diseases such as age-related macular degeneration (AMD), choroiditis, and myopic retinopathy. Photodynamic therapy (PDT) and anti-vascular endothelial growth factor (VEGF) drugs are approved treatment methods. PDT acts by selective dye accumulation, activation by laser light, and disruption an...
