The authors conducted a case-control study of risk factors for retinal vein occlusions using 87 patients with vein occlusions, chosen randomly from photographic files from their institution between 1985 and 1990, and a control group of 85 subjects 38 years of age (the youngest individual in the vein occlusion group) or older, who were randomly selected from the records of two general ophthalmologists in the authors' department. Certain risk factors for retinal vein occlusion were highly significant when subjects with retinal vein occlusion were compared with the control group. These risk factors included systemic hypertension (odds ratio [OR], 3.86; 95% confidence interval [Cl], 2.08 to 7.16), open-angle glaucoma (OR, 2.89; 95% Cl, 1.38 to 6.05), and male sex (OR, 2.61; 95% Cl, 1.43 to 4.79). Race, presence of diabetes mellitus, history of coronary artery disease or stroke, and family history of diabetes, glaucoma, coronary artery disease, or stroke were not significant risk factors in the population studied. Logistic analysis of the risk factors showed no interactions. Risk factors for branch retinal vein occlusion and central retinal vein occlusion were identical.

We examined the physical, sociodemographic, and psychosocial health status of diabetic Mexican Americans aged 45 to 74 years using data from the Hispanic Health and Nutrition Examination Survey. Diabetic Mexican-American women had lower education levels and lower employment rates in comparison with nondiabetics. Glaucoma, retinopathy, and activity limitation were more prevalent in diabetic than in nondiabetic men and women. Diabetic women also had a higher prevalence of hypertension, kidney problems, and cataracts. No significant differences were found in depression levels between diabetic and nondiabetic Mexican Americans of either sex. Among diabetics, duration of diabetes was associated with increased prevalence of stroke and activity limitation. These findings on the health status of diabetic Mexican Americans furthers our understanding of the health service needs of this population.

Of 3632 consecutive admissions to the Wilmer Ophthalmological Institute between July 1, 1987 and June 30, 1989, 27 patients required transfer to a medical or surgical service (0.74%). The major reasons for transfer included acute or decompensated cardiac disease (26%), poorly controlled diabetes mellitus (19%), acute renal failure (11%), coagulopathy, stroke, and hypertension (7% each). Only one transfer was a direct result of an anesthesia complication. The highest rates of transfers were associated with orbital (4.3%), enucleation/evisceration (3.1%), and glaucoma (2.3%) surgeries, while vitreoretinal surgery had the lowest rate of transfer (0.3%). Most of the transfers of patients with orbital disease were for management of related problems such as sinusitis or increased intracranial pressure.

Studies of this correlation have revealed correlation between stroke and minute blood volumes in reference subjects and in patients with open-angle glaucoma with the rheographic coefficient. No correlation at Stages II-IV glaucoma indicates a decompensation of ocular hemodynamics regulation mechanisms. Hemodynamic disorders should be corrected already during the first stage of the disease to prevent the disease progress to later stages.

Coenzyme Q10 (CoQ10) is an essential component of the mitochondrial membrane and plays an important role in the maintenance of normal cardiac function. To evaluate the effects of ocular timolol on the cardiovascular system and determine the protective effect of CoQ10, 16 patients with glaucoma were studied using impedance cardiography. Following instillation of 1 mg timolol maleate in each eye, heart rate (HR) and stroke index (SI) decreased, and total peripheral resistance index (TPRI) increased significantly. Reexamination was performed after 6 weeks of 90 mg oral CoQ10. Despite decreases in HR, percent changes in HR were significantly less after CoQ10 at 120 min. Stroke index showed an initial increase which was not observed without CoQ10. These data suggest that CoQ10 delayed the appearance of inotropic blockade of timolol and hastened the disappearance of chronotropic blockade. Additional study of six normal volunteers with 6 weeks of oral CoQ10 showed a similar decrease of intraocular pressure after timolol instillation as compared to those without CoQ10. Thus, administration of oral CoQ10 in patients receiving ocular timolol may be useful in mitigating cardiovascular side effects without affecting intraocular pressure in the treatment of glaucoma.

Primary care physicians have a vital role to play in identifying depression in their elderly patients. Diagnosis may be difficult, because symptoms are atypical and frequently include psychomotor agitation, somatic symptoms, and complaints of memory loss. Patients with medical illnesses, such as cancer, postmyocardial infarction, stroke, Parkinson's disease, and early Alzheimer's disease are particularly vulnerable to depression. Drugs that may cause depressive symptoms are digitalis at toxic levels, beta-blockers, centrally acting antihypertensives, immunosuppressants, and nonsteroidal anti-inflammatory agents. Cyclic antidepressants are the drugs of first choice. Selection depends on the patient's physical health and current medications and the side effect profile of the drug. Side effects are more pronounced in old age because of drug accumulation owing to slowed clearance. Troublesome side effects are anticholinergic effects, orthostatic hypotension, sedation, cardiotoxicity, and weight gain. The most useful antidepressants for geriatric patients are the secondary amines, desipramine and nortriptyline. The second-generation drug trazodone has the advantage of causing the least anticholinergic effects, but it is very sedating. Before treatment, the patient should have an electrocardiogram, liver function tests, tonometry, sitting and standing blood pressures, evaluation of urinary symptoms for outflow obstruction, review of current medications, and estimation of suicide risk. Cyclic antidepressants are contraindicated during recovery from myocardial infarction, in heart disease when there is severe impairment of myocardial performance, in seizure disorders, and in the presence of glaucoma or a large prostate. Drug interactions that may cause trouble can occur with epinephrine, MAO inhibitors, thyroid hormone, cimetidine, and centrally acting antihypertensives. Dosage should start low, increasing usually by 25 mg every 4 to 5 days until a therapeutic level is reached. Failure of a noradrenergic antidepressant after 4 to 5 weeks can be followed by a trial of a serotonergic drug. Drug serum level monitoring is useful for imipramine, desipramine, and nortriptyline. Monoamine oxidase inhibitors are effective in many elderly patients who are resistant to TCAs. Sympathomimetic drugs must be avoided with MAOIs. Elderly patients are at high risk of toxicity and drug interactions with lithium. Electroconvulsive therapy is useful for patients who do not respond to drug treatment, but medical complications, particularly cardiovascular, often occur in patients 75 or older. Many patients relapse after ECT. Psychotherapy together with pharmacotherapy may be the optimal treatment for elderly depressives. Older patients are more likely to become chronically depressed than younger patients. The risk of suicide in depressed elderly males is high, particularly in those with psychosocial problems, and depression rises with age.

Obtaining a valid informed consent from an elderly person, especially with possible senile dementia of the Alzheimer's type (SDAT), first may involve solving the practical problems of effective communication. Perceptual constraints that frequently occur in the elderly and that may interfere with communication, i.e., the sharing of information, are auditory and/or visual. The most common auditory obstacle, presbycusis (the hearing loss for pure tones due to normal aging) and other hearing impairments, may make the communication of any information about a proposed research project difficult, if not impossible, when not suspected and successfully overcome. Speech and language impediments, whether as a result of stroke or SDAT, are also common and need to be addressed if the person is to communicate his or her concerns and questions effectively with the researcher. Included in such constraints are the misunderstandings that arise from the use of confusing vocabulary, especially "medicalese." Presbyopia, cataract, and glaucoma are some of the visual constraints that may play an important role in making it difficult for the person to read the informed consent form. This article discusses these and other impediments to effective communication with SDAT elderly and makes suggestions how to obviate them.

The prevalence of chronic disease based on a mailed questionnaire was estimated as part of a continuing epidemiological study of a retirement community. The prevalence of eight chronic diseases (high blood pressure, angina, myocardial infarction, stroke, diabetes, rheumatoid arthritis, glaucoma, and cancer) was determined across all age and sex groups. The relationships between these diseases and several health related life-style practices were assessed. A health index summarizing five practices (smoking, alcohol consumption, exercise, sleep and obesity) was clearly related to the prevalence of disease.

From a group of 26 patients with proven stenosis or occlusion of the internal carotid artery, 8 were selected who had typically developing chronic ischemia of the globe. Four eyes had to be enucleated due to painful secondary glaucoma. The results of histological examination correlated with the clinical findings, showing fibrovascular occlusion of the chamber angle with incipient endothelialization, pronounced hyalinization of the ciliary body, venous stasis of the choroidal and retinal circulation, and a predominantly perivenous lymphocytic infiltration of the optic nerve. The causal mechanisms are discussed. Particular attention is given to blood flow factors in the orbital area (in 5 of the 8 patients Doppler sonography showed a reversal of flow in the supratrochlear artery on the same side as the globe ischemia). Diagnosis and therapy require an interdisciplinary approach, since besides treating the ophthalmological complications it is vital to ensure stroke prophylaxis by improving cerebral circulation.

Monocular pattern-shift visual evoked potentials were obtained in (i) 33 patients with unilateral non-hemorrhagic hemispheric infarction (age 50-79 years; 23 males, 10 females), (ii) 21 age- and sex-matched patient controls (control group or CGI) with no remote or recent stroke, normal neurological examination and similar incidence of diabetes mellitus, hypertension and heart disease, and (iii) 21 age- and sex-matched healthy elderly community volunteers (CGII). Subjects with history of glaucoma, cataracts, other media opacities or symptomatic retinal lesions were not considered or included in any of the 3 study groups. In addition, all subjects in each of the 3 groups had a normal ocular and fundoscopic examination. The mean interocular P100 latency difference in the stroke group was significantly greater than that in CGI or II (P less than 0.01). The mean interocular P100 amplitude ratio (small P100/large P100) in the stroke subjects was significantly different from that of CGI or II (P less than 0.02). The mean P100 latency on ocular stimulation ipsilateral to the side of infarction was significantly longer than that of either left or right ocular stimulation in CGI or II (P less than 0.01). The mean P100 latency on ocular stimulation contralateral to the side of infarction was similarly but less significantly longer than that on left or right ocular stimulation in CGI or II (P less than 0.05). Evidence of anterior visual pathway dysfunction was thus elicited in the stroke population using the technique.
