The Study of the Oculocardiac Reflex

Ophthalmologists now realize the importance of the oculocardiac reflex from ocular manipulation. The occurrence of cardiac disturbances has been recognized since 1908. Several authors have believed the mechanisms of the reflex affecting the pulse rate. the conduction system and myocardial contractibility of the heart. For the purpose of the recognition of this reflex, authors performed ocular compression and muscle traction after atropine injection or retrobulbar anesthesia in 135 persons. The results were noted that the reflex is blocked by intravenous atropine injection or retrobular anesthesia. while not by subconjunctival anesthesia or intramuscular atropine injection.

Clinical Application of the Anterior Chamber Paracentesis

The anterior chamber paracentesis has its history about 4 centuries long in the ophthalmic operations. Author recently applied this method to 31 clinical cases consisting of hypopyon, hyphema, juvenile cataract and foreign body in anterior chamber. Attempt was made via the subconjunctival route on the cases of hyphema and lens material in the anterior chamber, in contrast with the ordinary corneal limbus puncture on the discission of anterior lens capsule, or irrigation of hypopyon. Application of paracentesis in my series was selected on the cases of blood over a half of anterior chamber, and large amount of hypopyon, etc., and the favorable rasults were achieved.

A Case of Madan's Syndrome

Marfan's syndrome is another name of arachnodactyly and was firstly noted by Marfan in 1896. Salle found that ocular signs are also accompanied by this syndrome. Since then, many cases of this syndrome have been reported even in this country. The etiology of this syndrome is not exactly classified but is thought as an hereditorical and general developemental abnormalities of mesodermal origin. Authors report here a case of this syndrome in which ectopia lentis, lens opacity, organization of vitreous and iridodonesis are present.
