Purpose: To report on the management of an unusual case of post-goniotomy hypotony.

Observation: A 41-year-old female with pigmentary glaucoma presented with a post-goniotomy cyclodialysis cleft and signs of hypotony maculopathy. Indirect cyclopexy closed the visible cleft but did not resolve her hypotony, despite neither ultrasonographic nor gonioscopic evidence of an open cleft or communication channel.

Microphthalmia is defined by a globe axial length greater than or equal to 2 standard deviations below the age-adjusted mean and can occur as part of a broader syndrome. The presence of a colobomatous cyst with microphthalmia signifies failure of the embryonic neuroectodermal fissure to close appropriately during development of the globe, creating a protuberant globular appendage that inhibits normal growth and development of the eye itself. Cystic reaccumulation of fluid is common after aspiration or surgical removal.

The biggest risk factor for developing Alzheimer's disease (AD) is age. Depending on the age of onset, AD is clinically categorized into either the early-onset form (before age 60years old), or the late-onset form (after age 65years old), with the vast majority of AD diagnosed as late onset (LOAD). LOAD is a progressive neurodegenerative disorder that involves the accumulation of β-amyloid (Aβ) plaques and neurofibrillary tangles in the brains of elderly patients.

Transgenic models of Alzheimer's disease (AD) have made significant contributions to our understanding of AD pathogenesis, and are useful tools in the development of potential therapeutics. The fruit fly, Drosophila melanogaster, provides a genetically tractable, powerful system to study the biochemical, genetic, environmental, and behavioral aspects of complex human diseases, including AD. In an effort to model AD, we over-expressed human APP and BACE genes in the Drosophila central nervous system.
