Among myopia specialists, mydriatic eyedrops are the most favored approach, applied by almost 75% in North America and more than 80% in Australia. A 2015 review suggested that increased outdoor time protects young children from myopia. A 2020 study of global practice patterns used by paediatric ophthalmologists to decrease the progression of myopia showed behavioral intervention (counseling to spend more time outdoors and less time with near-work) to be favored by 25% of specialists, usually in addition to medications. Glasses and contacts
The use of reading glasses when doing close work may improve vision by reducing or eliminating the need to accommodate. Altering the use of eyeglasses between full-time, part-time, and not at all does not appear to alter myopia progression. The American Optometric Associations Clinical Practice Guidelines found evidence of effectiveness of bifocal lenses and recommends it as the method for "myopia control". In some studies, bifocal and progressive lenses have not shown differences in altering the progression of myopia compared to placebo.In 2019 contact lenses to prevent the worsening of nearsightedness in children were approved for use in the United States. This "MiSight" type claims to work by focusing peripheral light in front of the retina. Medication
Anti-muscarinic topical medications in children under 18 years of age may slow the worsening of myopia. These treatments include pirenzepine gel, cyclopentolate eye drops, and atropine eye drops. While these treatments were shown to be effective in slowing the progression of myopia, side effects included light sensitivity and near blur.
It is bounded by the inguinal ligament anteriorly, pectineal ligament posteriorly, lacunar ligament medially, and the femoral vein laterally. It normally contains a few lymphatics, loose areolar tissue, and occasionally a lymph node called Cloquets node. The function of this canal appears to be to allow the femoral vein to expand when necessary to accommodate increased venous return from the leg during periods of activity. Diagnosis
The diagnosis is largely a clinical one, generally done by physical examination of the groin. However, in obese patients, imaging in the form of ultrasound, CT, or MRI may aid in the diagnosis. For example, an abdominal X-ray showing small bowel obstruction in a female patient with a painful groin lump needs no further investigation. Several other conditions have a similar presentation and must be considered when forming the diagnosis: inguinal hernia, an enlarged femoral lymph node, aneurysm of the femoral artery, dilation of the saphenous vein, athletic pubalgia, and an abscess of the psoas. Classification
Several subtypes of femoral hernia have been described. Management
Femoral hernias, like most other hernias, usually need operative intervention. This should ideally be done as an elective (non-emergency) procedure. However, because of the high incidence of complications, femoral hernias often need emergency surgery. Surgery
Some surgeons choose to perform "key-hole" or laparoscopic surgery (also called minimally invasive surgery) rather than conventional "open" surgery.
