Ophthalmia neonatorum in Tanta prevalence of chlamydia trachomatis

During nine months, 112 infants 1-4 weeks old with purulent ocular discharge and 40 normal infants were studied opthalmologicaly and microbiologicaly for bacteria and chlamydia aetiology. Infants with conjunctivitis were divided into two groups : group [A] had no treatment and group [B] treated before with no response. Pathogenic bacteria were cultured in 49.1% of all cases. Chlamydia was found in 9.6% in group [A] and in 38% in group [B]. In other words Chlamydial ophthalmia neonatorum is not uncommon in Tanta

Retinal circulation time and flow in relations to blood viscosity in diabetics

The appearance of blood flow in the retinal arteries and its transient time to the retinal veins were documented in diabetics using flucrescein dye and the wide angle fundus camera. The time was correlated to the level of viscosity in the blood and type of retinopathy in 54 male juvenile diabetics and in 20 normal controls. In diabetics it was found that the retinal transient arterio venous time was shortend compared to normal, but was prolonged in the presence of hyperviscosity or retinopathy. The rapid retinal flow in diabetics without complications may be used as an early sign of retinal hypoxia and subsequent retinopathy

IgE and histamine levels in tears and serum in relation to clinical types and severity of vernal keratoconjunctivitis

The concentration of IgE antibodies and histamine in tears and serum of [44] patients with vernel keratoconjunctivitis [V.K.C] were measured. The levels compared to the levels in [15] Patients with allergic conjunctivitis [A.C] and [15] normal non atopic controls. It was found that IgE and histamine levels were significantly increased in patients with V.K.C than in patients with A.C, and in both than in normal subjects. IgE and histamine in tears were higher in palpebral than in bulbar V.K.C., and in severe than in mild grades of activity of V.K.C. IgE and histamine in serum were not changed in relation to the types or severity of the disease. After treatment it was obvious that, drop of histamine in tears was rapid and associated with comfort from symptoms, while the decrease in IgE was delayed and was associated with regressim of papillae or corneal infiltration. Accordingly, cortisone was found superior to sodium cromoglycate in management of the severe grade, and both were good in the modrate grade, while antistine privine was of value in the mild grade. One may suggest that determination of tear IgE and histamine are reliable diagnostic tests for management of V.K.C
