Here are a few of the effects heavy drinking can have on your eye health.

Pupils

Alcohol can cause slow pupil reactions. It slows down the iris’ ability to dilate and constrict. This might not seem to be too much of a problem at first but if you have been drinking alcohol, even a small amount, and then drive your pupils won’t react as quickly to oncoming car headlights, therefore dazzling your vision which could cause an accident. So even if you have drunk alcohol and it is under the legal limit for driving and you feel fine to drive, think again about the other effects the alcohol is having on your vision.

Vision

Drinking alcohol can not only affect your pupils but also your general visual performance, especially if you have been drinking heavily. The alcohol can weaken the eye muscles which can cause blurred or double vision and also can cause delayed reactions.

Peripheral Vision

Not only can your general vision be affected after heavy alcohol consumption but your peripheral vision can change. Alcohol can sometimes lower your peripheral vision sensitivity and this can give the sensation of tunnel vision.

Contrast Sensitivity

Eye Lid Twitching

Hiking Vs Trekking – The Differences

The terms appear for use interchangeably on many web sites and tour books. It becomes even extra perplexing while a few groups promote their boots as ‘hiking boots’ and then proceed to country that they can be used on long hikes. And while is a stroll a trek and whilst is it a hike? It turns into even greater complicated whilst the word trekking is used to refer to the ascent of a mountain, like Island Peak or Mera Peak in Nepal, both over 6000m and each requiring the usage of technical hiking gear. How can they be called ‘hiking peaks?’

The term ‘trekking’ is regularly used to refer to day walks in natural surroundings, on clearly marked paths. It is undertaken for leisure, undertaking and the purpose of exercising. A small day % is used to carry water, light weight fleece and snacks. In places such as Canada and New Zealand, the time period is regularly used interchangeably with rambling, hill walking or tramping.

‘Trekking’, through evaluation is taken into consideration to be extra strenuous, covers greater distances across varying terrains, and requires camping over night and wearing heavy packs with food, drowsing luggage and tools. The term is definitely derived from the Afrikaans paintings, trek, which comes from the Dutch word, trecken, regarding a prolonged and arduous journey over large distances and frequently, unchartered ground. It is frequently associated with the migration of human beings throughout land from one region to another.

Does this suggest then that if an afternoon hike is hard, over hard ground and via thick wooded area and not using a paths, that it’s miles a trek? In Australia, they could call this bushwhacking, and in different places they call it stamping. When you visit the Mountain Gorilla in Rwanda or Uganda, it’s miles a at some point hike, however via dense wooded area, over very choppy and tough terrain. No marvel there’s a lot confusion.

But let us no longer quit the confusion there. Anyone who has attempted to take out tour insurance to cover their ‘trekking’ or ‘trekking’ ride, could have determined that these sports are often listed as ‘hazardous pastimes’. In fact, a few insurance organizations even lump phrases like trekking and mountaineering collectively as through they may be used interchangeably or are synonymous The there are other organizations who classify any hikes over an altitude of 2000m as mountain climbing. Sorry Scotland, however it manner that your famous top, Ben Nevis (1352m), isn’t always a mountain in the end however virtually a trekking height

Corneal Transplants; What Are They

Penetrating Keratoplasty (PK)
This type of cornea transplant replaces the full thickness of the cornea with a healthy and clear donor tissue and is required when a cornea has been severely damaged or disease, and where no other option of surgery remains. PK can be carried out under local or general anaesthetic and takes about one to two hours to complete. During surgery, a central 8mm button of cornea is removed and a similar sized button of the donor cornea is stitched in with tiny stitches. After surgery vision will stay misty and/or cloudy for a few days and will improve gradually for about 12-18 months. Individual stitches may be removed from three months after the surgery, but complete stitch removal is not performed until at least one year after the surgery. Following surgery, and once fully healed, around 75% of transplant recipients have adequate vision to drive legally, but to get the best results from vision, glasses or contact lenses may need to be worn.

Deep Anterior Lamellar Keratoplasty (DALK)
This type of cornea transplant is a partial thickness transplant and replaces the front 99% of the cornea with a donor cornea. Unlike penetrating keratoplasty, DALK keeps the back layers of the cornea, the Descemet’s membrane and endothelium layer, in place and it is used as an alternative to PK, when these back layers of the cornea are healthy. The surgery itself is carried out much the same as PK, but just less donor cornea is used. Again, stiches are used to keep the donor tissue in place, but as only part of the cornea has been replaced, healing and visual recovery are usually quicker than what are seen with PK. To get the best vision following surgery, glasses or contact lenses may need to be worn.

Endothelial Keratoplasty (EK)
This type of cornea transplant is a partial thickness transplant and replaces only the back layers of the cornea. Unlike to above two transplants, EK can be further split into two methods; Descemet’s stripping endothelial keratoplasty (DSEK) and Descemet’s membrane endothelial Keratoplasty (DMEK). Both DSEK and DMEK are very similar and the procedure to carry them out is the same, but DMEK differs as the donor cornea tissue does not include any stromal layer tissue. The consultant ophthalmic surgeon will decide which surgery is necessary, depending on the damage or disease that is present. EK transplants are used when there is a problem at the back of the cornea. To help keep the cornea clear, the cells lining the inside of the cornea pump fluid to stop the cornea from swelling, if there are not enough cells, due to disease or damage, then the cornea starts to swell and vision will become cloudy. The surgery is carried out differently when compared to PK and DALK; it will again be under either local or general anaesthetic but a very small incision is made between the coloured and white part of the eye. The eye surgeon removes the dysfunctional endothelial cells through this opening and a disc of donor cells is placed back inside the eye. The donor endothelial cells are pressed to the back of the cornea with an air bubble and the patient will need to lie still for about 1 hour following surgery to make sure the air bubble stays in place. Occasionally, a few stitches to close the incision may be needed. Vision will stay misty or cloudy for a few days, and will get better over 3-4 months, as with all types of corneal transplants glasses or contact lenses may be needed after surgery to get the best results from vision
