Jinfei Tang, Ergang Du, Jie Wang
RATIONALE: Cyclodialysis cleft is a relatively rare but severe condition with persistent ocular hypotony, which can cause morphologic changes and visual loss. Here we report a case of a traumatic cyclodialysis cleft that was successfully managed with direct cyclopexy via anterior chamber perfusion. During the operation, if there is aqueous humor flowing out of the deep scleral incision, the cleft is not closed, and surgery should continue until there is no aqueous outflow. PATIENT CONCERNS: A 66-year-old man was treated for severe blunt ocular trauma of the left eye and a resultant cyclodialysis cleft, lens subluxation, choroidal detachment and a cataract...

Cataract is one of the most important causes of blindness worldwide, with age-related cataract being the most common one. Agents preventing cataract formation are urgently required. Substantial evidences point out aggravated oxidative stress as a vital factor for cataract formation. Nuclear factor (erythroid-derived 2)-like 2 (Nrf2)/Kelch-like erythroid-cell-derived protein with CNC homology (ECH)-associated protein 1 (Keap1) system is considered as one of the main cellular defense mechanisms against oxidative stresses...

Epidemiological data describing the prevalence of blindness and visual impairment in Haiti are sparse. The Haitian National Committee for the Prevention of Blindness (CNPC) estimates the prevalence of blindness at 1 %. Other regional data estimate moderate and severe visual impairment at 5% and 22%, respectively. IRIS Mundial (IM) is a non-governmental organization collaborating with the CNPC to develop eye care infrastructure in Haiti. To estimate the prevalence and causes of blindness and visual impairment on the Haitian island of Gonâve, to assist in planning of relevant eye care infrastructure...

As a highly potent reactive oxygen and nitrogen species, peroxynitrite (PON) has endogenous production in the eye ball and contributes to a variety of ocular disorders. In the current study the structural characteristics, chaperone-like activity and conformational stability of R54C mutant αA-crystallin (αA-Cry) were studied upon modification with PON and in the presence of three antioxidant compounds such as ascorbic acid (ASA), glutathione (GSH) and N-acetylcysteine (NAC) using gel electrophoresis and different spectroscopy methods...

For geriatric patients with hip fractures, the broken bone is the reason for admission, but only part of the overall disease. Indeed, it may be more helpful to consider the patient having geriatric hip fracture syndrome or sustaining a hip attack, as there are many associated medical, social, psychological, and other problems to which attention must be paid. To that end, we have identified a series of 10 steps, collected into a checklist, that can be undertaken for all patients with geriatric hip fracture. In homage to the maxim "we come into the world under the brim of the pelvis and go out through the neck of the femur," we defined our checklist by the acronym APGAR SCORE, named after the classic checklist of the same name used to assess a newborn child...

REVIEW
A O Minas Coroneo
Defending vision, our highest bandwidth sense, challenges human ingenuity. Replacing or repairing highly specialized but scarce tissue within constraints of transparency, tissue shape and alignment, tissue borders and pressure maintenance, presents special challenges. Many, mostly destructive surgical procedures, were developed prior to an understanding of underlying pathophysiology. For a number of conditions, both reconstructive and destructive procedures co-exist yet there are few guidelines as to the better approach...

OBJECTIVE: Cataracts are the most common ocular disorder in dogs. Phacoemulsification is the preferred treatment method among ophthalmologists, but the cellularity of the endothelium must be considered for its success, as endothelial lesions may produce permanent corneal decompensation. The objective of this study was to evaluate the effects of intracameral ascorbic acid, a known antioxidant, on the corneal endothelium of dogs undergoing phacoemulsification. ANIMAL STUDIED: In all, 40 eyes from 20 dogs, males and females from 7 to 12 years of age, were assessed for mature cataracts...

Posterior capsule opacification (PCO) is the most common complication after cataract surgery. So far, the only method for PCO treatment is the precisely focused laser surgery. However, it causes severe complications such as physical damages and neuron impairments. Here, a nanostructured photothermal ring integrated intraocular lens (Nano-IOLs) is reported, in which the rim of commercially available IOLs (C-IOLs) is decorated with silica coated Au nanorods (Au@SiO2 ), for high-efficient prevention of PCO after cataract surgery...

Acylglycerol kinase (AGK) is a mitochondrial lipid kinase that catalyzes the phosphorylation of monoacylglycerol and diacylglycerol to lysophosphatidic acid and phosphatidic acid, respectively. Mutations in AGK cause Sengers syndrome, which is characterized by congenital cataracts, hypertrophic cardiomyopathy, skeletal myopathy, exercise intolerance, and lactic acidosis. Here we identified AGK as a subunit of the mitochondrial TIM22 protein import complex. We show that AGK functions in a kinase-independent manner to maintain the integrity of the TIM22 complex, where it facilitates the import and assembly of mitochondrial carrier proteins...

Mutations in mitochondrial acylglycerol kinase (AGK) cause Sengers syndrome, which is characterized by cataracts, hypertrophic cardiomyopathy, and skeletal myopathy. AGK generates phosphatidic acid and lysophosphatidic acid, bioactive phospholipids involved in lipid signaling and the regulation of tumor progression. However, the molecular mechanisms of the mitochondrial pathology remain enigmatic. Determining its mitochondrial interactome, we have identified AGK as a constituent of the TIM22 complex in the mitochondrial inner membrane...

Antibiotics such as fluoroquinolones (FQLs) are commonly used to treat ocular infections but are also known to cause dermal melanocyte toxicity. The release of dispersed pigments from the iris into the aqueous humor has been considered a possible ocular side effect of the systemic administration of FQLs such as Moxifloxacin, and this condition is known as bilateral acute iris transillumination (BAIT). Bilateral acute depigmentation of iris (BADI) is a similar condition, with iris pigment released into the aqueous, but it has not been reported as a side effect of FQL...

OBJECTIVE: To examine the relationship between occupational exposure to ionizing radiation and the prevalence of lens changes in interventional cardiologists (ICs) and catheterization laboratory ("cath-lab") staff. BACKGROUND: Exposure to ionizing radiation is associated with the development of lens opacities. ICs and cath-lab staff can receive high doses of ionizing radiation without protection, and may thus be at risk for lens opacity formation. METHODS: We conducted a cross-sectional study at an interventional cardiology conference...
