BACKGROUND Detachment of photoreceptors from the underlying retinal pigment epithelium is seen in various retinal disorders such as retinal detachment and age-related macular degeneration and leads to loss of photoreceptors and vision. Pharmacologic inhibition of photoreceptor cell death may prevent this outcome. This study tests whether systemic administration of tauroursodeoxycholic acid (TUD...

It is well-known that the typical protein’s three-dimensional structure is relatively unstable in harsh conditions. A practical approach to maintain the folded state and thus improve the stability and activity of proteins in unusual circumstances is to directly apply stabilizing substances such as osmolytes to the protein-containing solutions. Osmolytes as natural occurring organic molecules ty...

Negative ion detachment in two-colour laser field is considered within the recent modification of Keldysh model which makes it quantitatively reliable. The general approach is illustrated by calculation of angular differential detachment rates, partial rates for particular ATD (Above Threshold Detachment) channels and total detachment rates for H − ion in bichromatic field with 1:2 frequency ra...

Detachment rhythms of immature Karoo paralysis ticks (Ixodes rubicundus) from their natural host, the rock elephant shrew (Elephantulus myurus), were investigated under laboratory and natural conditions. Larvae and nymphs detach mainly during the day. Peak detachment always occurred after the commencement of artificial as well as natural light cycles. The detachment of larvae appears to be more...

CHOROIDAL detachment following intra-ocular operation is a complication often encountered, but associated with other conditions or alone it is rare. It has been reported after orbital cellulitis, intra-ocular foreign body, tenonitis, scleritis, certain systemic diseases, and has also apparently occurred spontaneously. This report concerns a man who, at the age of 63, developed a choroidal detac...

SJS and TEN are variants of the same process, presenting as severe mucosal erosions with widespread erythematous, cutaneous macules or atypical targets. The cutaneous lesions often become confluent and show a positive Nikolsky sign and epidermal detachment. In SJS, epidermal detachment involves less than 10% of the total body skin area; transitional SJS-TEN is defined by an epidermal detachment...

Retinal detachment in adults with posterior segment coloboma is thought to be rhegmatogenous. Vitrectomy techniques are therefore used therapeutically. There is indirect evidence that subretinal fluid in retinal detachment, associated with optic nerve cavitation, is cerebrospinal fluid (CSF). We report 2 pediatric cases, referred for the management of coloboma-related retinal detachment, that p...

Multiple posterior segment complications can occur after LASIK. Posterior vitreous detachment, macular holes, retinal hemorrhages, retinal detachment, and several other complications have been described. A case of posterior vitreous detachment with epiretinal membrane in a young adult after LASIK is reported. LASIK surgeons must be aware of the possibility of posterior segment complications aft...

Retinal detachment often is a preventable cause of vision loss. There are three types of retinal detachments: exudative, tractional, and rhegmatogenous. The most common type is rhegmatogenous, which results from retinal breaks caused by vitreoretinal traction. Risk factors for retinal detachment include advancing age, previous cataract surgery, myopia, and trauma. Patients typically will presen...
