Complex cataract and glaucoma surgery
Complex cataract and glaucoma surgery Scott 7,064 Views • 3 years ago

Phacolytic glaucoma usually is associated with a mature or hypermature cataract and typically occurs in elderly patients. Today, phacolytic glaucoma is rare in the United States, found primarily in areas where access to care is poor. Will the increase in the number of under- and uninsured patients lead to an increase in this condition? Evaluation and Diagnosis Signs and symptoms. Patients typically report acute-onset pain, decreased vision, tearing and photophobia. Examination will reveal injection, corneal edema, elevated IOP, anterior chamber reaction with or without pseudohypopyon, particles on the lens capsule and anterior capsule wrinkling. Patient history. The duration of symptoms should be elicited; a delayed presentation of more than five days since onset can result in glaucomatous disc damage and poorer prognosis.¹ The ocular history may reveal that the patient decided against removal of an advanced cataract. Prior intraocular surgery or trauma may have left residual lens material that could cause phacoanaphylactic glaucoma or exacerbate infectious endophthalmitis. Visual acuity and visual potential should be assessed. Exam essentials. A complete ophthalmologic examination should be done. The eye should be inflamed, and the cornea may be edematous due to the high IOP. The anterior chamber will demonstrate massive inflammation and/ or pseudohypopyon. Gonioscopy is essential; it will help rule out angle closure due to phacomorphic glaucoma or neovascularization of the angle. Assess ment of the posterior pole should be performed to rule out vitreous hemorrhage (which can result in ghost-cell glaucoma) or vitritis (which may be associated with infectious endophthalmitis or panuveitis). If the view to the fundus is obstructed, B-scan ultrasonography also should be performed. Differential diagnosis. The differential diagnosis includes infectious endophthalmitis, phacoanaphylactic glaucoma, inflammatory glaucoma, glaucoma secondary to intraocular tumor, phacomorphic glaucoma, acute-angle closure glaucoma and neovascular glaucoma. Management Medication. Medical management is used to temporarily control the glaucoma and inflammation. Initial treatment consists of hyperosmotic agents, aqueous suppressants, anti-inflammatory drugs and cycloplegics. Surgery. Definitive treatment is removal of the lens via extracapsular cataract extraction with or without an IOL. Some ophthalmologists defer placement of an IOL until after the inflammation subsides; however, there is no significant difference in final visual acuity between those patients who did receive an IOL and those who did not.¹ If the phacolytic glaucoma is of long duration (more than seven days), a combined trabeculectomy may be needed to prevent postoperative IOP spikes.² In eyes with hypermature Morgagnian cataracts, one must be especially careful, as the capsule is fragile, the zonules are weak and the view is difficult due to the white, milky cortex. Vision limited to light perception on presentation is not a contraindication to performing cataract extraction. Surgical Tips For a planned extracapsular cataract extraction with a posterior chamber IOL, fashion a superior fornix-based conjunctival flap.³ Make a partial-thickness incision along the sclerolimbal junction superiorly for 120 degrees with a No. 69 blade. Forty-five degrees away, a paracentesis should be done to decompress the eye. The anterior chamber fluid can be withdrawn for analysis, to look for macrophages and high molecular-weight proteins. Inject balanced salt solution in a cannula to wash out any residual particulate matter, then inject Healon or viscoelastic into the anterior chamber. Make an incision entering the anterior chamber at the 12 o’clock position with a keratome. A 26-gauge cystotome mounted on a syringe is then introduced through the 12 o’clock incision and used to puncture the capsular bag. The milky cortex should be aspirated as much as possible, until the nucleus is visible. Withdraw the needle through the keratome incision, then inject Healon through the 12 o’clock incision into the capsular bag. Next, enlarge the corneoscleral keratome incision with curved Westcott scissors to 120 degrees. Perform a partial V-shaped capsulotomy; this can be done either with the cystotome or with an angled Vannas scissors. Place viscoelastic under the nucleus to float the nucleus and sever any adhesions between the nucleus and the capsule. The nuclear portion of the lens can then be removed with an irrigating vectis (lens loop) with or without gentle pressure at the inferior limbus (6 o’clock). Irrigate and aspirate the residual cortex with the Simcoe cannula. Inspect the capsular bag; if it is intact, place a posterior chamber IOL into the bag. Close the incision with several interrupted 10-0 monofilament nylon sutures and reattach the conjunctival flap. Potential Sequelae and Prognosis Postoperatively, the patient should be managed with topical steroids and/or aqueous suppressants and hyperosmotics if necessary. Vitreous opacification behind the posterior capsule occurs in a small percentage of eyes. These vitreous opacities are typically absorbed by one to two weeks postoperatively. IOP usually is controlled without antiglaucoma medications after the cataract removal. A detailed glaucoma evaluation (including repeat gonioscopy to assess for peripheral anterior synechiae, visual field and optic nerve status) should be done to assess the extent of glaucomatous damage. The prognosis is dependent on the duration of elevated IOP, PAS and optic nerve damage. In one study, patients who were older than 60 and whose glaucoma was present for more than five days did significantly worse than a comparison group of younger individuals with shorter disease duration.

Urinary Tract Infection Treatment
Urinary Tract Infection Treatment samer kareem 2,912 Views • 3 years ago

Urinary tract infections (UTIs) are infections of the urethra, bladder, ureters, or the kidneys, which comprise the urinary tract. E. coli bacteria cause the majority of UTIs, but many other bacteria, fungi, and parasites may also cause UTIs. Females have a higher risk for UTIs than most males, probably because of their anatomy; other risk factors for UTIs include any condition that may impede urine flow (e.g., enlarged prostate, kidney stones, congenital urinary tract abnormalities, and inflammation). Patients with catheters or those who undergo urinary surgery and men with enlarged prostates are at higher risk for UTIs.

Extradural Hematoma Surgery
Extradural Hematoma Surgery samer kareem 2,740 Views • 3 years ago

Epidural hematoma (EDH) is a traumatic accumulation of blood between the inner table of the skull and the stripped-off dural membrane. EDH results from traumatic head injury, usually with an associated skull fracture and arterial laceration.The inciting event often is a focused blow to the head, such as that produced by a hammer or baseball bat. In 85-95% of patients, this type of trauma results in an overlying fracture of the skull. Blood vessels in close proximity to the fracture are the sources of the hemorrhage in the formation of an epidural hematoma. Because the underlying brain has usually been minimally injured, prognosis is excellent if treated aggressively. Outcome from surgical decompression and repair is related directly to patient's preoperative neurologic condition. [1]

Tonsil stones are hard yellow or white formations that are located on or within the tonsils. It’s common for people with tonsil stones to not even realize they have them. Tonsil stones aren’t always easily visible and they can range from rice- to pea-sized. Tonsil stones rarely cause larger health complications. However, sometimes they can grow into larger tonsilloliths which can cause your tonsils to swell

The Brain and Cranial Nerves
The Brain and Cranial Nerves samer kareem 21,620 Views • 3 years ago

The brain is that part of the CNS contained within the cranial cavity (figure 13.1). It is the control center for many of the body's functions. The brain is much like a complex central computer but with additional functions that no computer can as yet match. Indeed, one goal in computer technology is to make computers that can function more like the human brain. The brain consists of the brainstem, the cerebellum, the diencephalon, and the cerebrum (table 13.1). The brainstem includes the medulla oblongata, pons, midbrain, and reticular formation. The structure of the brain is described in this chapter. Its functions are primarily discussed in chapter 14. Twelve pairs of cranial nerves, which are part of the PNS, arise directly from the brain. Two pairs arise from the cerebrum, nine pairs arise from the brainstem, and one pair arises from the spinal cord.

McMurray's Test
McMurray's Test samer kareem 13,124 Views • 3 years ago

McMurray's maneuver is used to detect the presence of meniscal tears. To detect a medial meniscal injury, the patient is put in a supine position with the knee in maximum flexion. One hand of the examiner is placed on the posteromedial margin of the involved knee and the other hand supports the foot. The tibia is then externally rotated, and the knee is extended slowly. The test is positive if there is an audible or palpable click or popping sensation during extension of the involved knee.

Porcelain Gallbladder
Porcelain Gallbladder samer kareem 6,650 Views • 3 years ago

Porcelain gallbladder is a condition characterized by calcium salt deposits in the wall of a chronically inflamed gallbladder. The calcifications can be thin or faintly visible, or may be amorphous, patchy, and thick. The gallbladder is generally large, but its size can vary considerably. Most porcelain gallbladders are associated with gallstones. A plain radiograph generally detects these, but computed tomography (CT) has a higher specificity; therefore, a CT scan is performed to confirm the diagnosis. Due to their high risk of gallbladder carcinoma, all patients with porcelain gallbladder should have an elective cholecystectomy.

Nephron
Nephron samer kareem 25,594 Views • 3 years ago

A nephron (from Greek νεφρός (nephros) meaning "kidney") is the basic structural and functional unit of the kidney. Its chief function is to regulate the concentration of water and soluble substances like sodium salts by filtering the blood, reabsorbing what is needed and excreting the rest as urine.
