Miniaturized high-resolution wide-field contact lens for panretinal photocoagulation
نویسندگان
چکیده
BACKGROUND AND OBJECTIVE We describe a miniaturized lightweight high-refractive-index panretinal contact lens for diagnostic and therapeutic visualization of the peripheral retina. INSTRUMENT DESIGN The miniaturized high-resolution wide-field contact lens includes three optical elements in a light (15 g) and miniaturized (16 mm footplate, 24 mm external aperture, and 21 mm vertical height) casing contributing to a total dioptric power of +171 diopters. This lens provides up to 165° visualization of the retina for diagnostic and therapeutic applications while allowing easier placement due to its miniaturization. CONCLUSION This new lens (50% lighter and 89% smaller) improves upon earlier contact lenses for visualization of the peripheral retina.

Scanning laser ophthalmoscopy and angiography with a wide-field contact lens system.
OBJECTIVE To perform fluorescein and indocyanine green angiography for large or peripheral chorioretinal structures using a contact lens system that provides a 5-fold increase in the field of view of a confocal scanning laser ophthalmoscope (SLO). METHODS Separate handheld contact and noncontact ophthalmoscopic lenses were manually aligned with the optical axis of a confocal SLO to demonstrat...
متن کاملPanretinal, high-resolution color photography of the mouse fundus.
PURPOSE To analyze high-resolution color photographs of the mouse fundus. METHODS A contact fundus camera based on topical endoscopy fundus imaging (TEFI) was built. Fundus photographs of C57 and Balb/c mice obtained by TEFI were qualitatively analyzed. RESULTS High-resolution digital imaging of the fundus, including the ciliary body, was routinely obtained. The reflectance and contrast of ...
متن کاملModern retinal laser therapy.
Medicinal lasers are a standard source of light to produce retinal tissue photocoagulation to treat retinovascular disease. The Diabetic Retinopathy Study and the Early Treatment Diabetic Retinopathy Study were large randomized clinical trials that have shown beneficial effect of retinal laser photocoagulation in diabetic retinopathy and have dictated the standard of care for decades. However, ...

BACKGROUND To report a case of proliferative diabetic retinopathy (PDR) exhibiting the appearance of scintillating particles presumed to be crystallin inside the intravitreal cavity after laser photocoagulation. CASE PRESENTATION A 56-year-old male patient presented at our outpatient clinic after becoming aware of decreased vision in his right eye. Ocular examination performed at the patient'...
متن کاملLong-term visual outcome in proliferative diabetic retinopathy patients after panretinal photocoagulation.
BACKGROUND There is the need for a long-term study on the visual outcome of panretinal photocoagulation (PRP) for proliferative diabetic retinopathy (PDR) patients. CASES We retrospectively reviewed the clinical course and visual results in 66 eyes of 59 patients with PDR who were followed-up for at least 10 years after argon or krypton laser PRP. OBSERVATIONS Thirty-nine eyes had stage B-I...
