Children presenting with congenital anophthalmos usually develop a smaller bony orbit, a constricted mucosal socket, and a shortened eyelid fissure. This causes problems when fitting these patients with a prosthesis. Clinical evaluation of the Wiese self-inflating hydrogel expanders has demonstrated their ability to expand the socket and eyelid fissure for inserting a more realistic prosthesis in shorter periods of time.
The study included 13 consecutive anophthalmic patients, eight unilateral and five bilateral. Each patient received a hemispherical osmotic tissue expander in the rudimentary mucosal socket and later a sphere implanted in the deeper soft orbital tissue.
The use of hydrogel expanders enlarged the lid and palpebral fissure in all children, with good cosmetic results. It allowed insertion of custom-made glass prostheses with good cosmetic appearance very early in life. Growth of the bony orbit may be stimulated successfully by these expanders in the soft orbital tissue.
The enlargement of constricted mucosal sockets and short palpebral fissures using self-inflating hydrogel expanders is a new and successful concept in treating congenital anophthalmos.
患有先天性无眼球的儿童通常会出现眼眶骨骼较小、结膜囊狭窄以及睑裂缩短的情况。这在为这些患者佩戴义眼时会引发问题。对维斯自膨胀水凝胶扩张器的临床评估表明，它们能够在更短时间内扩张结膜囊和睑裂，以便植入更逼真的义眼。
该研究纳入了13例连续性无眼球患者，其中8例为单侧，5例为双侧。每位患者在原始结膜囊中植入一个半球形渗透组织扩张器，随后在更深层的眼眶软组织中植入一个球体。
使用水凝胶扩张器使所有儿童的眼睑和睑裂增大，美容效果良好。这使得在儿童早期就能植入外观良好的定制玻璃义眼。这些扩张器可成功刺激眼眶软组织中骨骼眼眶的生长。
使用自膨胀水凝胶扩张器扩大狭窄的结膜囊和缩短的睑裂是治疗先天性无眼球的一种新的成功理念。
