Mucocele and Mycoses (Mucormycosis and Aspergillomycosis)

 Mucocele

These mucus-filled cysts may invade the orbital cavity in chronic sinusitis.

They displace orbital tissue and cause exophthalmos.

Treatment is required in the following cases:

❖ Displacement of the globe causes cosmetic or functional problems, such as lagophthalmos or limited motility.

❖ Compression neuropathy of the optic nerve results.

❖The mucocele becomes infected (pyocele).

Mycoses (Mucormycosis and Aspergillomycosis)

These rare disorders occur primarily in immunocompromised patients, such as those with diabetes mellitus or AIDS. The disorder often spreads from infected paranasal sinuses. The clinical picture is similar to those of inflam-matory orbital disorders.

Developmental Anomalies of the Eye Lens

Image
  Developmental Anomalies of the Lens Anomalies of lens shape are very rare.  Lenticonus  is a circumscribed conical protrusion of the anterior pole (anterior lenticonus) or posterior pole (poste-rior lenticonus). A hemispherical protrusion is referred to as  lentiglobus . Symptoms include myopia and reduced visual acuity. Some patients with Alport’s syndrome (kidney disease accompanied by sensorineural hearing loss and anomalies of lens shape) have  anterior  lenticonus.  Posterior lenti-conus  may be associated with a lens opacity (Fig. 7. 6 ). Treatment is the sameas for congenital or juvenile cataract. Microphakia  refers to a lens of abnormally small diameter. Any interrup-tion of the development of the eye generally leads to microphakia. This can occur for example in Weill-Marchesani syndrome (see Table 7. 5 ).

Optic Nerve

Image
  Optic Nerve Basic Knowledge The optic nerve extends from the posterior pole of the eye to the  optic chiasm  (Fig. 13. 1 ). After this characteristic crossing, the fibers of the optic nerve travel as the  optic tract  to the  lateral geniculate body.  Depending on the shape of the skull, the optic nerve has a total length of 35 – 55 mm. The nerve consists of: An intraocular portion.  An intraorbital portion.  An intracranial portion.   Intraocular Portion of the Optic Nerve The intraocular portion of the optic nerve is visible on ophthalmoscopy as the  optic disk . All the retinal nerve fibers merge into the optic nerve here, and thecentral retinal vessels enter and leave the eye here. The complete absence of photoreceptors at this site creates a gap in the visual field known as the  blindspot . Shape and size:  The optic disk (Fig. 13. 2 ) is normally slightly vertically oval with an average area of approximately 2.7 mm...

Curative Corneal Procedures

Image
  Curative Corneal Procedures Penetrating Keratoplasty  (Fig. 5. 18a ) Principle:  This involves replacement of diseased corneal tissue with a full-thickness donor graft of corneal tissue of varying diameter. A clear, regularly refracting button of donor cornea is placed in an opacified or irregularly refracting cornea. The corneal button is sutured with a continuous single or double suture (Fig. 5. 19 ) or with interrupted sutures. (For special considera-tions in corneal transplants, see also Morphology and healing.) Penetrating keratoplasty can be performed as an  elective procedure  to improve visual acuity or as an emergency procedure ( emergency kerato-plasty ). Emergency keratoplasty is indicated to treat a perforated or nonheal-ing corneal ulcer to remove the perforation site and save the eye ( tectonic ker-atoplasty ). Indications:  Corneal diseases that affect the full thickness of the cornealstroma (corneal scars, dystrophy, or degeneration) or pr...
