Vision Syndrome

Sasha Strul, Penny Straughn
There is currently no well-defined guideline for treatment and management of patients with keratitis-ichthyosis-deafness (KID) syndrome, and most patients will face disabling vision loss due to corneal neovascularization and cicatrization. We offer this case as an example of how we can improve visual acuity (VA) and quality of life even in advanced cases of corneal neovascularization. We showcase the use of gas-permeable (GP) contact lenses to provide useful, functional VA in a patient with long-standing visual impairment secondary to corneal neovascularization and irregularity due to KID syndrome...

Transforming growth factor beta-induced (TGFBI)-associated corneal dystrophies are a group of inherited progressive corneal diseases. One of these TGFBI-associated corneal dystrophies is Avellino corneal dystrophy, an autosomal dominant corneal dystrophy characterized by multiple asymmetric stromal opacities that potentially impair vision. Recently, a case with corneal dystrophy complicated by nephropathy possessing a pathogenic variant of the TGFBI gene was reported for the first time. Here, we report the second case with the same condition and the same mutation in the TGFBI gene...

Identification and characterization of the limbal epithelial stem cells (LESCs) has proven to be a major accomplishment in anterior ocular surface biology. These cells have been shown to be a subpopulation of limbal epithelial basal cells, which serve as the progenitor population of the corneal epithelium. LESCs have been demonstrated to play an important role in maintaining corneal epithelium homeostasis. Many ocular surface diseases, including intrinsic (e.g., Sjogren's syndrome) or extrinsic (e.g., alkali or thermal burns) insults, which impair LESCs, can lead to limbal stem cell deficiency (LSCD)...

Posterior reversible encephalopathy syndrome (PRES) or leukoencephalopathy syndrome was introduced into clinical practice in 1996 by Hinchey et al ., to describe unique syndrome, clinically expressed during hypertensive and uremic encephalopathy, eclampsia, and immunosuppressive therapy. Hyperperfusion with resultant disruption of the blood-brain barrier results in vasogenic edema, but not infarction, most commonly in the parieto-occipital regions. The severity of this clinical symptom varies. For example, the visual disturbance can manifest as blurred vision, homonymous hemianopsia, or even cortical blindness...

Posterior reversible encephalopathy syndrome (PRES) is a clinical condition that can cause different ophthalmological and neurological symptoms. Preeclampsia toxemia or eclampsia is one of the leading causes of PRES. Herein, we present a study of a 35-year old woman who gave birth to healthy twins at 35 weeks of gestation by cesarean section because of threatened preterm delivery. On the 1st postoperative day, the woman developed a severe headache, arterial hypertension, tachycardia, generalized tonic-clonic seizures, and loss of consciousness that persisted for about 2 min...

A 49-year-old man presented with a 1-week history of right facial paraesthesia with blurred vision and diplopia. Examination was normal apart from reduced facial sensation. Following appropriate neuroimaging, we considered a diagnosis of silent sinus syndrome. He underwent a middle meatal antrostomy with complete resolution of symptoms. Silent sinus syndrome results from occlusion of the osteomeatal complex, preventing normal aeration of the maxillary sinus. Maxillary sinus hypoventilation typically causes inferior displacement of the globe in the orbit (unilateral hypoglobus)...

Fibrillin microfibrils are extensible polymers that endow connective tissues with long-range elasticity and have widespread distributions in both elastic and non-elastic tissues. They act as a template for elastin deposition during elastic fibre formation and are essential for maintaining the integrity of tissues such as blood vessels, lung, skin and ocular ligaments. A reduction in fibrillin is seen in tissues in vascular ageing, chronic obstructive pulmonary disease, skin ageing and UV induced skin damage, and age-related vision deterioration...

Background and Aims: As most plants rely on pollination for persistence in communities, pollination interactions should be important determinants of plant community assembly. Here, trait and phylogenetic null modelling approaches were combined with pollinator interaction networks to elucidate the processes structuring flower colour assembly patterns in Asteraceae communities in Namaqualand, South Africa. Methods: Plant species were assigned to flower colour pattern categories (CPCs) that incorporate the complexity of the bulls-eye colour pattern, using pollinator vision models...
