Characterization of retinal function and structure in the MPTP murine model of Parkinson’s disease

open access: yesScientific Reports, 2022
In addition to well characterized motor symptoms, visual disturbances are increasingly recognized as an early manifestation in Parkinson’s disease (PD). A better understanding of the mechanisms underlying these changes would facilitate the development of

In vitro assessment of the biocompatibility of chemically treated silicone materials with human lens epithelial cells

open access: yesScientific Reports, 2022
Cytotoxicity testing is a regulatory requirement for safety testing of new ocular implants. In vitro toxicity tests determine whether toxic chemicals are present on a material surface or leach out of the material matrix.

Ocular and vision defects in preschool children. [PDF]

open access: yesBritish Journal of Ophthalmology, 1993
Ocular and/or vision defects are one of the commonest reasons for the referral of young children to hospital. In a survey of a birth cohort in one health district, 7.1% of children were diagnosed as having such defects by their fifth birthday; 2.1% were detected before the age of 2 years, and 5.1% between 2 and 5 years.
