Retinal Detachment (RD) refers to the separation of retinal nerve epithelia from pigment epithelia, resulting in the inability of photoreceptor cells to properly receive and conduct light signals, which can lead to irreversible visual impairment or even blindness in severe cases. RD can be divided into three categories: porosity, tractive and exudative. Among them, rheogenic retinal detachment is the most common, accounting for more than 80%, then this article will explore in depth - rheogenic retinal detachment!

Rhegmatogenous Retinal Detachment (RRD) is a common blinding disease in ophthalmology. It is mainly caused by retinal retinal retinal retinal detachment (RRD), which is characterized by vitreous fluid penetration into the subretinal space caused by retinal pores or cracks, resulting in the separation of nerve epithelium and pigment epithelium. If not treated in time, It can lead to irreversible visual impairment and even blindness. Retinal hole formation: Common causes include retinal degeneration (e.g. lattice degeneration, cystic degeneration), high myopia (thinning of the peripheral retina due to axial elongation of the eye), eye trauma, and a history of surgery. Most of the degeneration areas are located in the peripheral retina, and most of them are in the superior temporal quadrant. Vitreous factor: vitreous liquefaction and post-detachment (PVD) is a key factor in the penetration of liquefied vitreous into the retina through the hiatus. The mechanical tug of the vitreous body on the retina can aggravate the enlargement of the hole, resulting in the extension of the detachment range.

---

01 Common causes of high myopia: the eyeball is prolonged and the retina is thinner, which makes the local hole easily formed and becomes the "entrance" of detachment. Eye trauma: Blunt trauma or penetrating injury can directly destroy the integrity of the retina, resulting in hiatus and subsequent detachment. Posterior vitreous detachment: With age or due to genetic factors, vitreous degeneration and traction lead to the appearance of the hole. Abnormal eye development: Some congenital diseases, such as familial exudative vitreoretinopathy, may also increase the risk of RRD.

02 Clinical manifestations Flashing sensation: generally appears at the edge of the visual field. Floaters: The sudden appearance of many fluttering dark shadows in front of the eyes is caused by the detachment of the vitreous body. Visual field occlusion: like a curtain or curtain, it can be stationary, or it can be expanded with the continuous expansion of the RRD range, and the central vision will be seriously decreased when the macular area is involved. Visual deformation, visual loss: some patients with chronic retinal detachment will have visual deformation, slow visual loss, etc., and some may be accompanied by vitreous bleeding.

03 Diagnostic Methods Fundus examination: After mydriasis, the range of retinal detachment and the location of the hole were observed by indirect ophthalmoscope or three mirrors. The typical manifestations were gray eminence. Optical coherence Tomography (OCT) : can visually display the structural changes of each layer of the retina to help assess the extent of detachment and macular involvement. B-ultrasonography: It is suitable for the cases where the fundus cannot be directly observed due to the opacity of the vitreous body, to provide the degree of detachment and the location of the hole. Fluorescein fundus angiography: In difficult cases to assist the identification of hiatus and its surrounding lesions, to facilitate surgical planning. Perimetry: To assist in the assessment of visual field defects, and to confirm the clinical manifestations.

In medical practice, green light (with a wavelength of about 540nm) is generally considered the color of visible light that is most helpful in locating veins. Here’s the explanation:



1. Optical principle:

• Deoxyhemoglobin in Vein Finder has a higher absorption rate of green light, while surrounding tissues (such as skin and fat) reflect more green light. This contrast between absorption and reflection makes the veins appear as dark lines under green light, making them easier to identify.
  
  In the visible spectrum, green light (520-580nm) is close to the absorption peak of deoxygenated hemoglobin, optimizing the contrast between the veins and the surrounding tissue.
  
  
  
  2. Clinical application:
  
• Medical devices (such as venous imaging AIDS) often use green LED light sources or filters, especially for patients with thin veins, darker skin or obesity.
  
• Green background light may also be used in the operating room to enhance vascular visibility and assist medical staff in operation.
  
  3. Limitations of other colors:
  
• Red light has strong penetration but low contrast, because hemoglobin absorbs less red light;
  
• Blue light scatters more, which may reduce clarity;
  
• Near-infrared light is effective, but requires imaging technology to convert to visible light, not directly belonging to the visible spectrum.
  
  

  Green light has become the preferred visible light color for assisting vein localization by enhancing the contrast between hemoglobin absorption and tissue reflection, and is widely used in clinical difficult venipentesis scenes.

Zirconia Tubes for Industrial Heat Protection | 70% Fewer Failures

 

High-temperature equipment failures cost manufacturers over $2.8 billion annually in unplanned downtime (Frost & Sullivan, 2023).

For industries like metallurgy, chemical processing, and energy, yttria-stabilized zirconia (YSZ) tubes are proving to be a breakthrough solution, slashing failure rates by 70% through their unmatched thermal shock resistance (1,600°C tolerance) and wear-proof construction. Backed by ISO 13356 certification, these ceramic components are redefining reliability in extreme environments.

 

Industrial Furnace Liners for Metallurgical Smelting

 

Zirconia ceramic tubes are revolutionizing molten metal handling by replacing short-lived quartz and alumina liners in smelting furnaces. Engineered via isostatic pressing, these tubes achieve 99.5% density, eliminating micro-cracks that cause premature fracturing under thermal stress. Unlike traditional materials, the yttria-stabilized matrix retains structural integrity even after 1,000+ thermal cycles—a critical advantage validated by a 2022 Journal of Refractory Materials study showing YSZ liners last 8x longer than silicon carbide in copper smelters.

 

 

For example, a German steel mill reduced crucible replacement costs by $320,000/year after adopting zirconia tubes, achieving ROI within 7 months. The material’s ultra-low thermal conductivity (1.8 W/mK) also minimizes heat loss, cutting energy consumption by 25%.

 

Parameter	Alumina Tubes	YSZ Tubes
Thermal Shock Cycles	200	1,000+
Maintenance Interval	2 months	24 months
Energy Loss	18%	5%

 

 

Chemical Reactor Shields Resisting Corrosive Environments

 

In chemical plants, ceramic protection tubes are solving chronic leakage issues in HCl and sulfuric acid reactors. The non-porous surface of YSZ tubes prevents acid permeation, while their pH 0-14 resistance (per ASTM C623 testing) eliminates pitting corrosion—a flaw in polymer-lined steel pipes. Dow Chemical’s 2021 trial reported an 82% reduction in reactor shutdowns after switching molten sulfur handling systems to YSZ-based components.

One ethylene producer documented 50% lower spare-part inventories due to zirconia’s extended lifespan, alongside a 30% drop in maintenance labor hours. For plant managers, this translates to fewer unplanned outages and predictable OPEX.

 

 

Operational Impact:

• Harsh chemical compatibility: Resists HF, Cl₂, H₂SO₄, and NaOH
• Erosion rate: 0.02 mm/year (vs. 1.5 mm/year for stainless steel)

 

 

Thermal Insulation in Power Generation Systems

 

YSZ thermal protection tubes are gaining traction in gas turbine exhaust systems, where temperatures exceed 1,400°C. The material’s low thermal expansion coefficient (10.5×10⁻⁶/°C) prevents warping during rapid startups/shutdowns—a vulnerability that plagues metal alloys. Siemens Energy’s 2023 report highlighted a 70% reduction in turbine blade oxidation when using zirconia-coated exhaust guides.

A combined-cycle power plant in Texas cut annual repair costs by $540,000 after retrofitting their heat recovery steam generators (HRSGs) with YSZ insulation sleeves. The ceramic’s 2.2 W/mK conductivity ensures steady heat transfer, improving overall system efficiency by 12%.

 

 

Performance Summary:

• Operating temperature: 1,600°C continuous
• Thermal cycling lifespan: 4x longer than Inconel 718
• ROI period: 8 months (via downtime reduction)
