Ocular pathology in congenital heart disease.

PURPOSE: To describe the ocular findings in subjects with congenital heart disease (CHD). METHODS: In a prospective study, the same observer examined 240 consecutive patients with CHD admitted to the medical centre. Two independent geneticists performed identification of syndromes. RESULTS: The commonest anatomic cardiac anomalies were ventricular or atrial septal defects (62), tetralogy of Fallot (39), pulmonary stenosis (25), and transposition of the great arteries (24). The heart lesions were divided physiologically into volume overload (90), cyanotic (87), and obstructive (63). In all, 105 syndromic subjects included the velocardiofacial syndrome (18), Down's syndrome (17), CHARGE association (6), DiGeorge syndrome (5), Williams syndrome (3), Edwards syndrome (3), Noonan syndrome (3), VACTERL association (2), and Patau syndrome (trisomy 13) (2). The paediatric team recognized 51 patients as syndromic. Two independent geneticists recognized additional 54 patients as syndromic. Positive eye findings were present in 55% (132) and included retinal vascular tortuosity (46), optic disc hypoplasia (30), trichomegaly (15), congenital ptosis (12), strabismus (11), retinal haemorrhages (8), prominent eyes (7), and congenital cataract (6). There was a strong correlation between the retinal vascular tortuosity and both a low haematocrit (P=0.000) and a low arterial oxygen saturation (P=0.002). CONCLUSIONS: Patients with CHD are at a high risk for ocular pathology and need screening for various ocular abnormalities.

Lens minibar to facilitate refraction.

PURPOSE: To describe a lens minibar that facilitates refraction. METHODS: Ten lenses of 1-diopter increment were glued to form a hyperopic minibar (range from +1.00 to +5.00) and a myopic minibar (range from -1.00 to -5.00), the size of a credit card. RESULTS: The lens minibar allowed expedited refraction in children and in consultations that took place outside the clinic. CONCLUSION: The lens minibar is an inexpensive, small, lightweight tool that facilitates quick refraction.

Ocular findings in aplastic anemia.

OBJECTIVE: To analyze the ocular findings in aplastic anemia. DESIGN: Eighteen patients with aplastic anemia were examined. RESULTS: Ocular findings included cotton wool spots (38%), nerve fiber layer or preretinal hemorrhages (67%), vitreous hemorrhages (13%), a picture resembling central retinal vein occlusion (13%) and optic disk edema (6%). Preretinal hemorrhages were the presenting sign of aplastic anemia in 2 patients (13%). CONCLUSIONS: A blood profile is needed in patients with unexplained retinal hemorrhages. Patients with aplastic anemia need to avoid ocular massage and Valsalva maneuvers to decrease ocular morbidity.

Echocardiographic prevalence of mitral and/or aortic regurgitation in patients exposed to either fenfluramine-phentermine combination or to dexfenfluramine.

We evaluated the prevalence of valvular regurgitation in patients who have taken anorectic medications. Two-dimensional echocardiograms with color flow Doppler were recorded in 200 consecutive patients referred to a major metropolitan hospital for evaluation of cardiac function because of a history of anorectic medication use. Each patient filled out a questionnaire at the time of the visit or through telephone contact. Each echocardiogram was reviewed by 2 observers. The degree of valvular regurgitation was graded by a consensus of both observers. Significant valvular regurgitation was defined as at least moderate mitral regurgitation (MR) or at least mild aortic regurgitation (AR), as recommended by the Food and Drug Administration and Centers for Disease Control and Prevention. For all patients having taken anorectic drugs, there was a 5% prevalence of at least moderate MR, a 12% prevalence of at least mild AR, and a 16% prevalence of significant MR and/or AR. Patients with significant AR and/or MR were older than those without significant valvular regurgitation (49+/-12 vs 44+/-11 years, p = 0.03). Patients with significant MR and/or AR had a longer exposure duration (8 vs 6 months, p = 0.049) to anorectic drugs. There was no difference in weight loss between those with and without significant regurgitation (p = NS). The 2 largest subgroups were patients who took the fenfluramine-phentermine combination (n = 127) and those who took dexfenfluramine alone (n = 42). The prevalence of significant MR and AR was 5% and 9% for the fenfluramine-phentermine group and 0% and 14% for the dexfenfluramine group, respectively. There was also a high subthreshold level of MR and AR in these patients.
