Two Cases of () Endophthalmitis Manifesting With Unusual Epiretinal Deposits.

This article describes two cases of delayed-onset () endophthalmitis 1 month after cataract surgery manifesting with unusual epiretinal deposits. Both patients were referred for persistent inflammation after cataract surgery. After failing to respond to a vitreous tap with injection of antibiotics, the patients underwent pars plana vitrectomy and in one of the cases partial posterior capsulectomy for a posterior capsular plaque.

Simultaneous presentation of Kimura disease and angiolymphoid hyperplasia with eosinophilia.

Kimura disease and angiolymphoid hyperplasia with eosinophilia are rare disease entities that can manifest as subcutaneous nodules, plaques, or papules of the head and neck, and less commonly the orbit and ocular adnexa. The merits of each entity have been debated with regard to whether they are truly individual or are separate points on a single spectrum. Current opinion favors the former.

Electrical stimulation in normal and retinal degeneration (rd1) isolated mouse retina.

Stimulus threshold and response latencies were measured for electrically elicited retinal ganglion cell responses in retina isolated from the eyes of normal and retinal degenerate (rd1) mice. Stimulation of the ganglion cell-side in normal retina yielded a significantly lower mean threshold and shorter latency when compared with stimulation of the photoreceptor side in normal retina. The latency of the ganglion cell-side stimulation in normal retina also proved to be significantly shorter than the latency for stimulation of the ganglion cell side in rd1 retina.

Retinal prosthesis for the blind.

Most of current concepts for a visual prosthesis are based on neuronal electrical stimulation at different locations along the visual pathways within the central nervous system. The different designs of visual prostheses are named according to their locations (i.e.
