Gonioscopy reveals a heavily pigmented trabecular meshwork and a Sampolesi’s line, which is pigment deposited anteriorly to Schwalbe’s line (Fig. Although pseudoexfoliation is infrequent in the United States, it accounts for more than 50% of open-angle glaucoma in Scandinavia. The zonules are weak, and synechiae are often present between the iris and anterior lens capsule. Capsular delamination caused typically by exposure to intense heat, as seen in glassblowers. A 24-year-old man with sarcoidosis presents with an intraocular pressure of 35 mmHg in the right eye and 32 mmHg in the left eye. On examination, you notice 2+ cell and flare in both eyes as well as significant posterior synechiae and mutton- fat keratic precipitates. Intensive topical steroids and a cycloplegic should decrease the inflammatory load and break the synechiae to prevent angle closure from becoming an issue in the future. However, miotics are contraindicated because they may cause further synechiae and precipitate angle closure. They also increase permeability of blood vessels and may contribute to an increase in inflammation. Prostaglandin agonists or analogues may also increase inflammation and should be avoided. The aggressiveness with which the pressure is lowered depends a great deal on optic nerve cupping. The same patient returns 14 days later with pressures of 40 mmHg and 45 mmHg in the right and left eye, respectively. Exam reveals minimal cell and flare in each eye as well as a significant decrease in the keratic precipitates. He has been using prednisolone acetate 1% every hour and atropine 1% three times ⁄day. The differential of increased intraocular pressure in this situation includes: & Steroid response. Provided the angle is open and without neovascularization, the most likely cause is response to steroids. The increased intraocular pressure may occur anywhere from a few days to years after initiating therapy. The response has been noted in or around the eye after oral and intravenous administration of steroids and even with inhalers. Patients with Cushing’s syndrome with excessive levels of endogenous steroids are also at risk. A topical nonsteroidal agent may help decrease inflammation without increasing intraocular pressure. Fluorometholone and loteprednol (Alrex, Lotemax) are also less likely to increase intraocular pressure than other formulations of steroids; however, they have less potency in decreasing inflammation. A Krukenberg spindle (arrow) is made blurred vision, eye pain, and halos of pigment deposited on the endothelium in around lights after exercise or pupillary pigmentary dispersion syndrome. If no optic disc damage is noted and the visual fields are normal, the patient may be observed. Treatment for intraocular pressure over 28 mmHg is usually indicated, although this point is controversial.

Both may show signs and of potential agents (most of which are rarely encountered symptoms similar to those seen with flu, including fever, naturally), their sometimes long incubation periods and chills and muscle aches. Anthrax resulting from consequent delayed onset of disease, and their potential inhalation of spores is the form of illness that would likely for secondary transmission. This illness would initially occurring pathogens, agents used by bioterrorists may resemble a viral respiratory illness and then would be genetically engineered to resist current therapies and progress to severe shortness of breath and hypoxia.

Exogenous source involves refer to all types of infections acquired by the patients transmission from patient to patient or from health care while being treated in hospital, as also by hospital staff worker to patient. It can also occur after exposure of members, volunteers, visitors, workers, salespersons and a susceptible patient to a contaminated environmental delivery personnel, etc. He demonstrated that modification of such practices led to Control Measures control of such infections.

It is felt that a brief account of The most common type of oral cancer is squamous cell oral diseases is called for because these form a significant carcinoma. Sixty percent of oral cancers are well part of morbidity and even mortality [through oral advanced by the time they are detected, even though cancer]. Sufficient attention is often not paid to these physicians and dentists frequently examine the oral cavity. Still, oral cancer accounts for approximately 3 percent of all cases of cancer in the United States. Major Statements As regards India, useful and reliable insights into The major statements regarding oral diseases that etiology and risk of oral cancer in men and women is underline the basis and reason for the above monograph1 provided by an elaborately designed and analyzed case deserve to be presented here at the outset so as to provide control study from three centers in South India a backdrop for discussion of the oral problems of public comprising 591 cancer cases and matched 582 health importance, with special reference to India. Smoking or manual worker and various indicators of poor cessation significantly decreases the increased risk of oral hygiene were associated with significantly oral cancer within 5 to 10 years. This male female • Halitosis, diminished taste and smell acuity are difference was maintained when paan chewing with common side effects of smoking. In an earlier case control study from Tata Memorial tobacco usage, it was found that the frequency of Hospital,6 Rao et al found that in addition to chewing, tobacco habit was associated with the prevalence of smoking and drinking, nonvegetarian diet was also leukoplakia indicating a positive dose-response significantly associated with oral cancer. The dose-response relationship was A large case-control study of oral and pharyngeal stronger for the smoking habit than for the chewing cancer conducted in four areas of the United States habit. Because of the large study size, it could be shown that Oral Mucosal Diseases the risks of these cancers among nondrinkers increased with amount smoked, and conversely that the risks Smoker’s Palate among nonsmokers increased with the level of alcohol Smoker’s palate is seen especially among heavy pipe- intake.

However, multiplicative rather than additive manner and were palatal keratosis associated with reverse smoking as seen increased more than 35-fold among those who in some parts of the world, is a premalignant lesion. Cigarette, cigar, and pipe especially in women, though it seems to be decreasing smoking were separately implicated, although it was now. These frequencies blacks, and among males and females, and showed little were lower compared to earlier studies done in the 60s difference when oral and pharyngeal cancers were and 70s in the districts of Visakhapatnam and analyzed separately.

Man lives in close contact with animals like • Chronic case ending in recovery, disability or death. Morbidity is measured as incidence or prevalence rates, which are expressed as the number of cases per unit Pathogenesis population (per thousand, lakh or million). When it 18 Everyone is potentially in a phase of prepathogenesis applies to occurrence of new cases, it is called incidence with respect to some diseases. Details are given in the chapter on vital Sporadic: When only isolated cases are reported here statistics. There is no tendency to disease in a given population depends on the agent, spread at one place or at one time. Short-term fluctuations result in an increase (or Pandemic: When an epidemic appears simultaneously decrease) in the number of cases in a community. Zoonoses are diseases that high incidence of upper respiratory infections in are transmitted naturally between man and vertebrate winter and of cholera in rainy season. Examples are plague, rabies, anthrax, cyclic fluctuations are the occurrence of influenza brucellosis, hydatid disease, kyasanur forest disease and pandemics every 7 to 10 years, of rubella every 6 typhus. Exotic: This is the label given to a disease imported The proportion of susceptible individuals in the from outside and not present in the country earlier. For “herd” increases year after year with the result that example, if cases of yellow fever occur in India one day, an outbreak occurs. Secular fluctuations refer to changes in morbidity An epidemiologist may be able to forecast an epidemic on the basis of known agent, host and rates over a long period of time, often decades. For example, an epidemic of Examples are a decreasing trend in occurrence of malaria may be expected when there is high rainfall and diphtheria and polio. An increase through 2 standard The spectrum of disease may be defined as the deviations serves as a warning and an increase through sequence of events that occur in the human host from 3 standard deviation calls for active community control the time of contact with the etiologic agent up to the measures. The following terms are used to express point of the ultimate outcome, which may be fatal in various grades of incidence and prevalence of the extreme cases. The term spectrum of disease is synonymous with Epidemic: When the number rises to ten or more/ “gradient of infection” in relation to infectious conditions. The gradient of infection refers to the sequence of Outbreak: When there is sudden reporting of a large manifestations of illness in a host, reflecting host number of new cases, the population having been response to the infectious agent. Food poisoning and cholera often aware of only a small proportion of the spectrum of a breakout suddenly. This is what Endemic: When the infectious agent has taken a is called “The tip of the iceberg” as information on the foothold in a population which is naturally and partially submerged portion is not available. But the inapparent protected because of occurrence of the disease over a cases are important for their role in transmission.

Children can safely receive full-time occlusion of the sound eye for up to 1 week per year of life before the next follow-up visit without significant risk of inducing occlusion amblyopia in the sound eye. Penalization refers to the intentional degradation of visual acuity in the sound eye by either optical or pharmacologic means. For example, the sound eye might be effectively blurred by intentional undercorrection of its refractive error, using atropine drops to prevent accommodation, or both. Translucent filters can be placed over the spectacle lens of the sound eye to degrade the vision. Penalization techniques are best suited for patients with a high degree of hyperopic refractive error in the sound eye and in whom the amblyopia is mild to moderate (20/100 or better). Pediatric Eye Disease Investigator Group: A comparison of atropine and patching treatments for moderate amblyopia by patient age, cause of amblyopia, depth of amblyopia, and other factors. Pediatric Eye Disease Investigator Group: The course of moderate amblyopia treated with atropine in children: experience of the amblyopia treatment study. The decision is less clear when there is some persistent deficit in visual acuity. If poor compliance can be ruled out, many practitioners continue to patch until no further improvement is noted after three consecutive treatment intervals (3–4 weeks each per interval). The eye examination and refraction should also be repeated to detect uncorrected refractive error or structural lesions. These guidelines may be modified, especially if there is a component of organic amblyopia. Once treatment is discontinued, children should be periodically rechecked to detect recurrences. Although the critical period has passed, significant improvements in adulthood have been reported in cases in which the sound eye was lost to enucleation. The presence of central fixation in the amblyopic eye before the loss of the sound eye seemed to be the single most important predictor of the extent of visual improvement. Studies looking at the potential use of pharmacologic agents such as levodopa to recover vision from amblyopic eyes in visually mature patients have demonstrated only small and temporary improvements. Generally speaking, color vision is not affected by amblyopia, although some investigators have found mild abnormalities in color perception. Eyes with severe amblyopia, particularly those with loss of foveal fixation, tend to demonstrate such abnormalities more consistently than eyes with milder degrees of amblyopia. In which of the following conditions is amblyopia most likely to occur: Congenital esotropia, Accommodative esotropia, Intermittent exotropia, or Constant exotropia? Patients with this condition, particularly if there is significant anisometropia, are less likely to alternate fixation than patients with congenital esotropia or exotropia. Patients with intermittent exotropia are unlikely to develop amblyopia, because they spend a fair amount of time being bifoveal. What is the effect of neutral density filters on the vision of an amblyopic eye compared with a normal eye? The visual acuity of a normal eye is progressively reduced by neutral density filters, whereas that of an amblyopic eye may remain unchanged or even improve slightly. This finding has led investigators to postulate that the vision in an amblyopic eye more closely resembles that normally occurring under scotopic conditions (i. The crowding phenomenon refers to a loss of spatial acuity when optotypes are presented in close proximity, or surrounded by other visual details, rather than in isolation. The crowding phenomenon is seen in both normal and amblyopic eyes but tends to be much more pronounced in amblyopia.
