Retinal rods and cones underlie scotopic and photopic vision, respectively. Their pigments exhibit spontaneous isomerizations (quantal noise) in darkness due to intrinsic thermal energy. This quantal noise, albeit exceedingly low in rods, dictates the light threshold for scotopic vision.

Subjects/methods: This was a single-centre, multi-surgeon, retrospective analysis of 50 consecutive cases of PGI for uveitic glaucoma performed between April 2019 and August 2021. Primary outcomes include: complete and qualified success (IOP ≥5 mmHg to ≤21 mmHg with ≥20% IOP reduction) or failure (IOP exceeding the success criteria, additional glaucoma procedures, no perception of light vision).
Article Synopsis
- Multiple sclerosis (MS) is a disease that damages myelin, making myelin water imaging essential for understanding this damage.
- This study aimed to analyze various brain water compartments, including myelin water fraction (MWF), in both MS patients and healthy controls using advanced MRI techniques.
- Results showed that MWF values were significantly lower in MS patients' normal-appearing white matter compared to healthy controls, indicating disrupted myelin integrity in MS.
Article Synopsis
- * Analyzed data from 207 eyes over two years showed no significant differences in visual acuity, intraocular pressure, or glaucoma medication use between the two groups, though more cataracts were noted in optometrist-treated eyes.
- * Overall, the study concluded that both optometrists and ophthalmologists have similar SLT treatment outcomes, but ophthalmologist-treated eyes had higher medication use and lower rates of subsequent surgery.
