Comparison of hydrophobic and hydrophilic intraocular lens in preventing posterior capsule opacification after cataract surgery

Medicine, 2017
Background: Posterior capsular opacification (PCO) is a common long-term complication of cataract surgery. Intraocular lens design and material have been implicated in influencing the development of PCO.

Integration of Cholesterol Oxidase‐Based Biosensors on a Smart Contact Lens for Wireless Cholesterol Monitoring from Tears

Advanced Intelligent Systems, EarlyView.
The combination of a parity‐time symmetry wireless technology with a cholesterol sensor integrated into a smart contact lens enables high‐sensitivity cholesterol sensing at low concentration. Cholesterol plays a critical role in physiological functions, but elevated levels increase the risk of cardiovascular disease.

Pathology features and the results of treatment of two cases of posterior choroidal leiomyoma

BMC Ophthalmology, 2020
Background Posterior choroidal leiomyoma is an extremely rare tumor, to our knowledge, less than 10 cases reported in the literature. The definite diagnosis can be confirmed by immunohistochemistry, and local resection is preferable to enucleation for ...

Establishment of a novel alloxan‐induced rabbit model exhibiting unique diabetic retinal neuropathy features assessed via ERG + VEP

Animal Models and Experimental Medicine, EarlyView.
Study workflow. Neuroretinal changes were observed in alloxan‐induced diabetic rabbits, while the retinal vasculature remained unaffected, indicating the successful establishment of a diabetic neuroretinal model. Abstract Background Diabetic retinal neuropathy (DRN) leads to significant visual impairment; however, no existing animal model fully ...

Systems genetics identifies a role for Cacna2d1 regulation in elevated intraocular pressure and glaucoma susceptibility

Nature Communications, 2017
Glaucoma is a multi-factorial blinding disease in which genetic factors play an important role. Elevated intraocular pressure is a highly heritable risk factor for primary open angle glaucoma and currently the only target for glaucoma therapy.

Anatolian ground squirrel (Spermophilus xanthoprymnus) retina: Comparative expression of synaptophysin, NeuN, calbindin‐D28k, parvalbumin, glial fibrillary acidic protein, and Iba‐1 during pre‐hibernation and hibernation

The Anatomical Record, EarlyView.
Abstract Hibernation induces significant molecular and cellular adaptations in the retina to maintain function under reduced metabolic conditions. This study aimed to investigate the expression of neuronal, synaptic, and glial markers in the retina of Spermophilus xanthoprymnus during pre‐hibernation and hibernation periods using immunohistochemical ...

Use of Rabbit Eyes in Pharmacokinetic Studies of Intraocular Drugs.

Journal of Visualized Experiments, 2016
The intraocular route of drug administration enables the delivery of high concentrations of therapeutic drugs, while minimizing their systemic absorption. Several drugs are administered into the anterior chamber or vitreous, and the intraocular injection
