Interventions for asymptomatic retinal breaks and lattice degeneration for preventing retinal detachment.

Background: Asymptomatic retinal breaks and lattice degeneration are visible lesions that are risk factors for later retinal detachment. Retinal detachments occur when fluid in the vitreous cavity passes through tears or holes in the retina and separates the retina from the underlying retinal pigment epithelium. Creation of an adhesion surrounding retinal breaks and lattice degeneration, with laser photocoagulation or cryotherapy, has been recommended as an effective means of preventing retinal detachment.

Comparison of standardized clinical classification with fundus photograph grading for the assessment of diabetic retinopathy and diabetic macular edema severity.

Purpose: To compare evaluation by clinical examination with image grading at a reading center for the classification of diabetic retinopathy and diabetic macular edema.

Methods: Action to Control Cardiovascular Risk in Diabetes (ACCORD) and Family Investigations of Nephropathy in Diabetes (FIND) had similar methods of clinical and fundus photograph evaluation. For analysis purposes, the photographic grading scales were condensed to correspond to the clinical scales, and agreement between clinicians and reading center classification were compared.

Mysteries regarding the surgically reattached retina.

Purpose: To present contemporary information regarding the continued inability to reliably predict visual acuity following successful retinal reattachment surgery.

Methods: Literature review.

Results: Anatomical results of surgery for retinal detachment continue to be far superior to visual results.

Differences in pulsatile ocular blood flow among three classifications of diabetic retinopathy.

Purpose: Choroidal blood flow may be determined by pulsatile ocular blood flow (POBF) measurements. In the present study, the POBF of diabetic patients with increasingly severe retinopathy was compared with that in nondiabetic control subjects.

Methods: The study was a masked cross-sectional analysis.
