Fluctuations of intraocular pressure during the day in open-angle glaucoma, normal-tension glaucoma and normal subjects.

PURPOSE: The aim of the present paper is to describe the variations in intraocular pressure (IOP) during the day in normals, in patients with primary open-angle glaucoma (POAG) and in patients with normal-tension glaucoma (NTG). IOP represents one of the most important risk factors for glaucoma. However the IOP value is not constant during the day and IOP fluctuation could influence the diagnostic and prognostic evaluation of the glaucomatous disease. METHODS: For this purpose IOP was evaluated every 2 h from 8 a.m. to 8 p.m. in one randomized eye of 33 normal subjects, 95 POAG and 50 NTG patients. RESULTS: The results show that the highest IOP values were detectable in the morning in all three groups. The lowest values were found in the early afternoon hours. These variations were most evident in POAG patients. The daily IOP fluctuations were directly proportional to IOP level. CONCLUSION: The study evidents that a single tonometric evaluation, especially if done in the first hours of the afternoon, is not sufficient to correctly evaluate the IOP-related risk in glaucoma patients. If the pressure peaks are important in determining the extent of glaucomatous damage in NTG patients IOP should not have an important role in optic nerve head damage. The use of diurnal curves seems to be mandatory for the assessment of IOP-related risk and of efficiency of the therapeutic approach.

[Treatment of herpetic endogenous uveitis with acyclovir by the systemic route].

Seventeen patients with presumed chronic herpetic uveitis of all anatomic types underwent systemic treatment with oral and/or intravenous, acyclovir. The diagnosis of herpes had been established on data from serological tests of the aqueous humor. Results were judged according to corticodependance and visual acuity. Results were all the more positive as treatment was more prolonged and also correlated with the dose of acyclovir injected intravenously or taken orally every day. Follow-up ranged from 6 months to several years.

[Viral uveitis].

The role of neurotropic virus in the etiopathogeny of uveitis is being emphasized by recent findings. Serology of aqueous humor is the first step towards the diagnosis since it indicates in many cases a local production of specific antibodies. Different entities seem to correspond to different viral specificities. The relationship between measles virus and multiple sclerosis may be one of the most fascinating aspects of this problem.

Azelastine eye drops reduce conjunctival hyperresponsiveness to hyperosmolar glucose challenge in children with asymptomatic mite conjunctivitis.

Mite allergy is characterized by a continuous allergen exposure. Persistent inflammation is therefore always detectable; and during symptomless periods as well. It has been reported that mite allergic patients also present a nonspecific hyperreactivity to different stimuli, including hyperosmolar solution. Since azelastine was previously demonstrated to be able to reduce allergic inflammation, the aim of the study was to investigate the effects of the drug on nonspecific conjunctival hyperreactivity in mite-allergic patients. Twenty children with mite allergy were studied. A hyperosmolar conjunctival challenge was performed before and after azelastine eye drops or placebo treatment for a period of 2 weeks. It was found that patients treated with azelastine eye drops showed a significant reduction in nonspecific conjunctival hyperreactivity compared to the placebo group (p = 0.018). It was concluded that azelastine eye drops are able to reduce the nonspecific hyperreactivity present in subjects with mite allergy.
