Regardless of the presence of fundus pigmentation or ONH atrophy, ONH MBR and ONH CBF were highly correlated, suggesting that MBR in the ONH tissue is usable for interindividual and intergroup comparisons.

TNFα plays a critical role in RD-induced photoreceptor degeneration. This pathway may become an important target in the prevention of RD-induced photoreceptor degeneration.

The detection rates and levels of various cytokines had different patterns in POAG and NVG patients, suggesting distinctive alterations in the microenvironment in different types of glaucoma.

We investigate the metabolomic profile of reactive persulfides and polysulfides in the aqueous and vitreous humors. Eighteen eyes of 18 consecutive patients with diabetes mellitus (DM) and diabetic retinopathy underwent microincision vitrectomy combined with cataract surgery. Samples of the aqueous and vitreous humors were collected and underwent mass spectrometry-based metabolomic profiling of reactive persulfides and polysulfides (polysulfidomics). The effect of reactive polysulfide species on

SAF has an independent relationship with PDR in patients with type 2 diabetes. SAF measurement with an autofluorescence reader is a non-invasive way to assess the risk of DR. SAF may, therefore, be a surrogate marker candidate for the non-invasive evaluation of DR.

Rhegmatogenous retinal detachment (RRD) is a serious condition that can cause blindness without surgical treatment. RRD occurs when a retinal tear or hole allows fluid to accumulate below the retinal surface, causing the retina to separate from the underlying layers. RRD is difficult to treat because each case is unique, varying with the location, size, and duration of the detachment, as well as patient age. The first successful methods to reattach the retina in RRD used thermocautery to repair

These findings indicate that eyes with both preoperative BCVA ≥ 0.5 and FT < 400 μm have a significantly better chance of obtaining a postoperative decimal BCVA ≥ 1.0 following idiopathic ERM removal.

Heads-up, 3D system-assisted 27GMIVS with minimal illumination enabled excellent intraoperative visualization of retinal tissues, caused minimal phototoxicity to the macular retinal cells, and might therefore represent the next step in the development of an ideal, minimally invasive method of treating macular disease.

In a normal population, MBR was affected by IOP in both the large vessel and capillary areas of the ONH, but not by SBP. MV was also affected by age and sex, while MT was stable independent of age or sex.

IVB had a suppressive effect on circulation in eyes with DME but not in those with BRVOME. This suggests that this noninvasive and objective biomarker may be a useful part of pre-IVB evaluations and decision-making in DME.

Retinal diseases related to ischemia, such as diabetic retinopathy, are the main cause of blindness worldwide. However, the pathogenesis of these diseases remains unclear, as does the time course of associated changes in ocular blood flow. Laser speckle flowgraphy (LSFG), which uses the laser speckle phenomenon to detect and quantify ocular circulation, is a promising candidate for a noninvasive method to measure ocular blood flow in living eyes. A recently developed LSFG measurement parameter,

Although the study had a short follow-up period, primary MIVS appears to be safe and feasible for giant retinal tear surgery.
