Human amniotic membrane graft removal and histopathologic evaluation following closure of a full thickness macular hole.

Purpose: Human amniotic membrane (hAM) grafts have been used to close persistent macular holes in recent years. The results from these surgeries are promising with improved closure rate and vision. However, there is lack of data for what happens to these membranes and how long the tissue should remain inside the patient's eyes.

Pediatric cavernous sinus and superior ophthalmic vein thrombophlebitis complicated by peri-venous orbital abscesses.

Purpose: This case report documents a 13-year-old male with bilateral cavernous sinus thrombosis and left superior ophthalmic vein thrombosis secondary to sphenoid sinusitis who subsequently developed peri-venous orbital abscesses.

Observations: Although the patient initially improved clinically with intravenous antibiotic therapy and therapeutic anticoagulation, his symptoms returned and repeat imaging demonstrated two well-circumscribed, rim-enhancing lesions in the left orbit concerning for abscesses. Surgical intervention revealed that these purulent collections were contiguous with the superior and inferior ophthalmic veins with the superior collection also containing hemorrhagic material.

Caring for Older Adults With Self-Reported Vision Impairment: Findings from the National Study of Caregiving.

Purpose: The purpose of this study was to examine caregiving relationships for older adults with vision impairment (VI).

Design: Cross-sectional study with a nationally representative sample.

Methods: Setting: the National Health and Aging Trends Study linked to the National Study of Caregiving, Year 2011.

Caring for Older Adults With Vision Impairment and Dementia.

Background And Objectives: Dementia and vision impairment (VI) are common among older adults but little is known about caregiving in this context.

Research Design And Methods: We used data from the 2011 National Health and Aging Trends Study, a nationally representative survey of Medicare beneficiaries, linked to their family/unpaid helpers from the National Study of Caregiving. Vision impairment was defined as self-reported blindness or difficulty with distance/near vision.
