Halo vision:
Medical causes
(Handbook of Signs & Symptoms (Third Edition))
Cataract
Halo vision may be an early symptom of painless, progressive cataract formation
The glare of headlights may blind the patient, making nighttime driving impossible. Other features include blurred vision, impaired visual acuity, and lens opacity, all of which develop gradually.
Corneal endothelial dystrophy
Typically, halo vision is a late symptom
Impaired visual acuity may also occur.
Glaucoma
Halo vision characterizes all types of glaucoma
Acute angle-closure glaucoma — an ophthalmic emergency — also causes blurred vision, followed by a severe headache or excruciating pain in and around the affected eye. Examination reveals a moderately dilated fixed pupil that doesn’t respond to light, conjunctival injection, a cloudy cornea, impaired visual acuity and, possibly, nausea and vomiting.
Chronic angle-closure glaucoma is usually asymptomatic until pain and blindness occur in advanced disease. Sometimes, halos and blurred vision develop slowly.
With chronic open-angle glaucoma, halo vision is a late symptom that’s accompanied by a mild eye ache, peripheral vision loss, and impaired visual acuity.

Costovertebral angle tenderness:
Medical causes
(Handbook of Signs & Symptoms (Third Edition))
Calculi.
Infundibular and ureteropelvic or ureteral calculi produce CVA tenderness and waves of waxing and waning flank pain that may radiate to the groin, testicles, suprapubic area, or labia. The patient may also develop nausea, vomiting, severe abdominal pain, abdominal distention, and decreased bowel sounds.
Perirenal abscess.
Causing exquisite CVA tenderness, perirenal abscess may also produce severe unilateral flank pain, dysuria, a persistent high fever, chills, erythema of the skin and, sometimes, a palpable abdominal mass.
Pyelonephritis (acute).
Perhaps the most common cause of CVA tenderness, acute pyelonephritis is commonly accompanied by a persistent high fever, chills, flank pain, anorexia, nausea and vomiting, weakness, dysuria, hematuria, nocturia, urinary urgency and frequency, and tenesmus.
Renal artery occlusion.
With renal artery occlusion, the patient experiences flank pain as well as CVA tenderness. Other findings include severe, continuous upper abdominal pain; nausea; vomiting; decreased bowel sounds; and a high fever.
Renal vein occlusion.
The patient with renal vein occlusion has CVA tenderness and flank pain. He may also have sudden, severe back pain; a fever; oliguria; edema; and hematuria.

Glaucoma:
Causes and incidence
(Professional Guide to Diseases (Eighth Edition))
Chronic open-angle glaucoma results from overproduction of aqueous humor or obstruction to its outflow through the trabecular meshwork or the canal of Schlemm. (See Normal flow of aqueous humor, page 1184.) This form of glaucoma, which is estimated to be present in 1% to 2% of people older than age 40, is frequently familial in origin and affects 90% of all patients with glaucoma. Diabetes and systemic hypertension have also been associated with this form of glaucoma.
Acute angle-closure (narrow-angle) glaucoma results from obstruction to the outflow of aqueous humor due to anatomically narrow angles between the anterior iris and the posterior corneal surface, shallow anterior chambers, a thickened iris that causes angle closure on pupil dilation, or a bulging iris that presses on the trabeculae, closing the angle (peripheral anterior synechiae).
Blacks are four times more likely to have this disorder than whites, and people with a family history of open-angle glaucoma are twice as likely to develop it than people without a family history of this disorder. The use of systemic anticholinergic medications, such as atropine or eye dilation drops, in a person who’s already at high-risk for acute glaucoma increases the risk. Other risk factors include farsightedness and age-related changes that create an increase in intraocular pressure.
Congenital glaucoma occurs when there is an abnormal fluid drainage angle of the eye. It may be caused by congenital infections such as TORCH virus (toxoplasmosis, other [varicella, mumps, parvovirus, human immunodeficiency virus], rubella, cytomegalovirus, and herpes), Sturge-Weber syndrome, or retinopathy of prematurity.
Secondary glaucoma can result from uveitis, trauma, or drugs (such as steroids). Neovascularization in the angle can result from vein occlusion or diabetes.

Simple goiter:
Causes and incidence
(Professional Guide to Diseases (Eighth Edition))
Simple goiter occurs when the thyroid gland can’t secrete enough thyroid hormone to meet metabolic requirements. As a result, the thyroid gland enlarges to compensate for inadequate hormone synthesis, a compensation that usually overcomes mild to moderate hormonal impairment. Because thyroid-stimulating hormone (TSH) levels are generally within normal limits in patients with simple goiter, goitrogenicity probably results from impaired intrathyroidal hormone synthesis and depletion of glandular iodine, which increases the thyroid gland’s sensitivity to TSH. However, increased levels of TSH may be transient and therefore missed.
Endemic goiter usually results from inadequate dietary intake of iodine, which leads to inadequate secretion of thyroid hormone. Since the introduction of iodized salt in the United States, cases of endemic goiter have virtually disappeared.
Sporadic goiter commonly results from the ingestion of large amounts of goitrogenic foods or the use of goitrogenic drugs. Goitrogenic foods, such as rutabagas, cabbage, soybeans, peanuts, peaches, peas, strawberries, spinach, and radishes, contain agents that decrease thyroxine (T4) production. Goitrogenic drugs include propylthiouracil, iodides, phenylbutazone, para-aminosalicylic acid, cobalt, and lithium. In a pregnant woman, these substances may cross the placenta and affect the fetus.
Inherited defects may be responsible for insufficient T4 synthesis or impaired iodine metabolism. Because families tend to congregate in a single geographic area, this familial factor may contribute to the incidence of both endemic and sporadic goiters.
Females are more commonly affected than males. Incidence increases after age 40.

Glaucoma:
Causes
(Handbook of Diseases)
The cause of glaucoma varies according to the type of disorder:
❑ Chronic open-angle glaucoma results from overproduction of aqueous humor or from obstructed outflow of aqueous humor through the trabecular meshwork or the canal of Schlemm. This form of glaucoma frequently runs in families and affects 90% of all patients with glaucoma.
❑ Acute angle-closure (narrow-angle) glaucoma results from obstructed outflow of aqueous humor caused by anatomically narrow angles between the anterior iris and the posterior corneal surface, shallow anterior chambers, a thickened iris that causes angle closure on pupil dilation, or a bulging iris that presses on the trabeculae, closing the angle. Adhesions in the angle, referred to as peripheral anterior synechiae, may be the cause.
❑ Secondary glaucoma can result from uveitis, trauma, or drugs such as steroids. Neovascularization in the angle can result from vein occlusion or diabetes.
