Lens Induced Glaucoma

Lens induced glaucoma is caused by the leakage of lens material in one’s eye due to damage to the optic nerve. Leakage is usually caused by a dense or late cataract. This glaucoma can be open-angle or angle-closure. Lens induced glaucoma requires special attention and care because, unlike other types of glaucoma, it cannot be ignored and, if left untreated, can result in loss of peripheral vision.

Symptoms of Lens-Induced Glaucoma

There are several symptoms that indicate Lens-induced glaucoma. Among the most common are:

  • Pain in the eyes
  • Loss of sight
  • Redness
  • Fading of visual clarity

 

Other symptoms that others may experience include:

  • Clouding of the eyes
  • Tearing
  • Corneal edema
  • Photophobia (a discomfort in the eyes that is felt because of the contact with high levels of light or by the occurrence of physical sensitivity within the eyes)

 

The Causes of Lens-Induced Glaucoma

Angle-closure

  • Due to swelling of lens (phacomorphic glaucoma) 
  • Due to discoloration of lens (ectopia lentis)

 

Open angle

  • Due to the leakage of lens proteins through the capsule of mature/hypermature cataract (phacolytic glaucoma)
  • Due to the obstruction of the meshwork after cataract treatment
  • Due to capsulotomy
  • Due to ocular trauma caused by fragments of lens (lens-particle glaucoma)
  • Due to hypersensitivity to own lens protein after a cataract surgery (phacoantigenic glaucoma)

 

Lens induced glaucoma is caused by the leakage of lens materials through the capsule of a developed cataract. Leakage of lens material from one’s lens can enter the eye’s drainage system, causing obstructions in the outflow of the normal aqueous liquid within the eye. This can result in aqueous buildup inside the eye, increasing eye pressure and causing optic nerve damage.

Prevention measures for Lens Induced Glaucoma

  • Regular eye and diabetic examination 
  • Family health history plays a major role. Understand and examine the same. Glaucoma can be a hereditary
  • Build a regular and safe exercise routine
  • Wear eye protection
  • Take only prescribed eye drops  

 

There are various types of Lens Induced Glaucoma.

  • Phacolytic glaucoma
  • Phacomorphic glaucoma
  • Lens particle glaucoma
  • Phacotopic glaucoma
  • Phacoanaphylatic uveitis with secondary glaucoma

 

Lens induced glaucoma Diagnosis

  • When it comes to Phacomorphic glaucoma, symptoms include eye pain, decreased vision, the formation of a mature cataract, and increased intraocular pressure.
  • Ectopia lentis differs from person to person depending on the condition of the lens, but when it is dislocated, it causes angle closure and pupillary blockage. People typically experience eye pain, decreased visual clarity, and difficulty placing objects, particularly near vision.
  • Phacolytic glaucoma causes eye pain, photophobia, vision loss, and high conjunctival hyperemia. A prominent cell or white particle in one’s anterior chamber, corneal edema, an increase in intraocular pressure, and the sign of mature cataract are used to diagnose such glaucoma.
  • The symptoms of lens-particle glaucoma usually appear after a few days, weeks, or even months or years. An accurate diagnosis includes a previous surgery or trauma. A few clinical findings of these include elevated intraocular elements and signs of cortical lens particles in the anterior chamber.
  • Keratic precipitates, anterior chamber flare response, and residue in lens materials are all clinical features of Phacoantigenic glaucoma. This type of glaucoma occurs between 1 and 14 days after cataract surgery.

 

Treatment for Lens-Induced Glaucoma

Lens-induced glaucoma necessitates immediate attention and prompt treatment, as it can lead to serious consequences if left untreated, such as intractable glaucoma caused by peripheral anterior synechiae triggered by ongoing inflammation.

Furthermore, this could result in the development of pupillary membrane and, eventually, a blockage in one’s pupillary. If the lens particles are not removed from the eye, they can cause permanent damage to the aqueous outflow channels.

However, treatment varies depending on the severity of the pupillary block dislocation. When there is a subluxation but no pupillary block, intraocular pressure treatment is recommended. A laser iridectomy is recommended when there is a serious pupillary block. The lens is removed when there is a complete anterior dislocation.
