Abstract

A multifunction ophthalmic examination apparatus includes a shallow dome screen (1B) and a deep dome screen (1A), i.e., the entire dome screen (1), having a different depth from the shallow one and constituted of the shallow dome screen (1B) and the peripheral part of the entire dome screen (1). The deep dome screen (1A) or the shallow dome screen (1B) is driven so that either the deep dome screen (1A) or the shallow dome screen (1B) comes to a position where an ophthalmic examination image is projected by a projector (2) depending on the type of the ophthalmic examination to be conducted. When this state is set up, the projector (2) projects an ophthalmic examination image onto either the deep dome screen (1A) or the shallow dome screen (1B). With this, the multifunction ophthalmic examination apparatus using the dome screens enables various ophthalmic examinations.

Description

technical field [0001] The present invention relates to a multifunctional ophthalmic examination device capable of performing various examinations as ophthalmic examinations. Background technique [0002] Currently, there are approximately 18 kinds of ophthalmic examinations, and a technique described in Patent Document 1 below is known as a prior art capable of performing various ophthalmic examinations with a single device. The ophthalmic apparatus described in this patent document 1 aims at measuring visual acuity and visual field or retinal sensitivity with the same apparatus. Specifically, it describes an ophthalmology apparatus capable of measuring night vision, dark-adapted vision, dynamic vision, and retinal sensitivity. [0003] Patent Document 1: Japanese Patent Laid-Open No. 2003-93344 [0004] However, in the above-mentioned ophthalmic apparatus, various ophthalmic examinations cannot be performed with the conventional apparatus configuration. For example, the...
