Macular Hole Progression after Intravitreal Bevacizumab for Hemicentral Retinal Vein Occlusion

open access: yesCase Reports in Ophthalmological Medicine, 2011
Macular edema secondary to retinal vein occlusion is commonly being treated with off-label intravitreal bevacizumab with good outcomes. A significant reduction in macular edema and improvement in visual acuity is seen following such a treatment with no ...

Evolution of demarcation line after pneumatic retinopexy—a case report

open access: yesBMC Ophthalmology, 2023
Background Demarcation line in a rhegmatogenous retinal detachment (RD) is a classic finding noted in chronic cases. In this case report, we describe a case of evolution of post-operative demarcation line after pneumatic retinopexy (PnR) in a subtotal ...

Towards the Next Generation of Retinal Neuroprosthesis: Visual Computation with Spikes [PDF]

open access: yespublished 2019, 2020
Neuroprosthesis, as one type of precision medicine device, is aiming for manipulating neuronal signals of the brain in a closed-loop fashion, together with receiving stimulus from the environment and controlling some part of our brain/body. In terms of vision, incoming information can be processed by the brain in millisecond interval.

In vivo functional and structural retina imaging using multimodal photoacoustic remote sensing microscopy and optical coherence tomography [PDF]

open access: yesarXiv, 2021
We have developed a multimodal photoacoustic remote sensing (PARS) microscope combined with swept source optical coherence tomography for in vivo, non-contact retinal imaging. Building on the proven strength of multiwavelength PARS imaging, the system is applied for estimating retinal oxygen saturation in the rat retina.

Functional Circuitry of the Retina.

open access: yesAnnual Review of Vision Science, 2015
The mammalian retina is an important model system for studying neural circuitry: Its role in sensation is clear, its cell types are relatively well defined, and its responses to natural stimuli-light patterns-can be studied in vitro. To solve the retina,

Programmable retinal dynamics in a CMOS mixed-signal array processor chip [PDF]

open access: yes, 2003
The low-level image processing that takes place in the retina is intended to compress the relevant visual information to a manageable size. The behavior of the external layers of the biological retina has been successfully modelled by a Cellular Neural ...
