Piloplex, a new long-acting pilocarpine polymer salt. A: Long-term study.

Thirty eyes of 15 patients with open-angle glaucoma were followed up for a period of up to 1 year while being treated with Piloplex eye drops containg a new long-acting pilocarpine polymer salt. Average morning intraocular pressure (IOP) values during treatment with pilocarpine hydrochloride administered 4 times daily was 20.5 mmHg. Average morning IOP values during Piloplex medication administered only twice daily were 19.8 to 18.2 mmHg (range of averages on 14 sessions). These findings indicate the lower average pressure during Piloplex medication and show its prolonged hypotensive effect. Both medications contained an equivalent total daily amount of pilocarpine. Throughout the 1-year study period no adverse side effects were reported, and only 1 patient complained of local sensitivity reaction. Visual disturbances characteristic of pilocarpine eye drops were reduced from 3 times a day on pilocarpine hydrochloride 4 times daily to once a day on Piloplex twice daily.

Carcinoembryonic antigen in aqueous humor of patients with primary malignant choroidal melanoma.

Carcinoembryonic antigen levels were simultaneously determined in the aqueous humor and in the plasma of the 3 patients with primary choroidal malignant melanoma undergoing enucleation. An elevated carcinoembryonic antigen level was detected in the aqueous humor of 1 patient with no increase in plasma CEA level. In the other 2 patients no such elevation was found. A local increase of CEA levels produced by the tumor is likely to occur. Further studies are required of CEA levels of patients with primary malignant choroidal melanoma as an aid in diagnosis and treatment of this condition.

A clinical trial with Piloplex--a new long-acting pilocarpine compound: preliminary report.

A clinical comparison of the effect of Piloplex (an emulsion containing a new pilocarpine polymer compound) to that of pilocarpine hydrochloride 2% q.i.d.hloride on the intraocular pressure (IOP) was performed on 93 eyes of 51 open-angle glaucoma cases. Clinical studies showed that Piloplex produced a prolonged therapeutic effect, this being consistent with the slow release pattern it has displayed during in vitro experiments. Comparison of diurnal IOP measurements of 84 eyes have shown that when treated with Piloplex, 11 b.i.d., 58 eyes (69%) were under control (IOP values less than 20 mm Hg), whereas only 34 of these 84 eyes (40.5%) were under control when treated with pilocarpine hydrochloride 2% q.i.d. The overall mean diurnal IOP value of the 84 eyes during the treatment with Piloplex, 11 b.i.d., was lower by 2.89 mm Hg (P less than 0.005) than the overall mean diurnal IOP of the same eyes while treated with pilocarpine hydrochloride 2% q.i.d.

Anterior uveitis in ankylosing spondylitis: a histocompatibility study.

The occurrence of acute anterior uveitis in ankylosing spondylitis was compared in 53 HLA-B 27 positive and 12 HLA-B 27 negative patients with this disease. Uveitis was found in HLA-B 27 positive patients only. These results suggest that uveitis and ankylosing spondylitis are independent diseases occurring on their own and strongly associated with HLA-B 27.

Sialochemistry of KCS patients.

Sialochemistry was used to detect salivary gland involvement in KCS patients. Significantly elevated IgA was found in 52% of the patients, potassium in 48% and sodium in 32%. No correlation between the grade of Schirmer's test and the extent of changes in salivary composition was observed. The results indicate that salivary IgA, K and Na concentrations can be used for detection of salivary gland involvement of KCS patients.

Spontaneous extrusion of intraocular foreign body after 11 years.

A case of spontaneous extrusion of intraocular foreign body after 11 years is presented. Despite being magnetic and containing mostly iron the foreign body could not be removed in repeated magnet trials. It was retained in the ciliary body region for a very long time without causing siderosis. The foreign body was spontaneously extruded without any signs of intraocular inflammation.

Histocompatibility antigens (HLA) and open angle glaucoma.

In 70 patients with primary open angle glaucoma and 70 unrelated controls of identical ethnic origin, the prevalence of different HLA antigens were examined. There were statistically no significant differences in the incidence of the antigens in both groups. There was no association between specific HLA antigen and primary open angle glaucoma.

Fundus lesions in rheumatoid arthritis.

Cotton wool exudates were found in a patient during a flare-up of seropositive rheumatoid disease with polyarthritis and pericarditis. After therapy with cortisone a concomitant improvement of the cardiac arthritic and fundal lesions was observed. It is suggested that the fundal lesions in this patient were due to the rheumatoid disease.

Bee and wasp stings of the eye. Retained intralenticular wasp sting: A case report.

Two different stages should be considered in the management of bee and wasp stings to the eye. The first is the acute stage of activity of the specific insect venom on the structures the eye. The reaction of the eye to the particular insult is considered here in regard to the anterior and posterior segments of the eye. The second stage is that of the retained intraocular foreign body, the inert sting. Little is known about the reaction of the eye to the presence of chitinous sting and its effect on the structures of the eye. We report a follow-up study of a sting retained for 28 years, and emphasise the benign and quiescent course of the case. Guidelines for treatment and management in such cases are described.
