Laser shrinkage of the ciliary processes. A treatment for malignant (ciliary block) glaucoma

Area of Science:

• Ophthalmology
• Glaucoma Research
• Anterior Segment Surgery

Background:

• Malignant glaucoma is characterized by shallow anterior chambers.
• The exact cause of malignant glaucoma remains debated.
• An unusual relationship between ciliary processes and lens equator is observed in affected patients.

Purpose of the Study:

• To propose a hypothetical cause for anterior chamber shallowing in malignant glaucoma.
• To investigate the role of anterior aqueous flow obstruction at the lens equator.
• To evaluate the efficacy of laser treatment for malignant glaucoma.

Main Methods:

• Observation of ciliary processes and lens equator in malignant glaucoma patients.
• Formulation of a hypothesis involving relative block of forward aqueous flow.
• Application of laser shrinkage of ciliary processes in treatment-resistant cases.

Main Results:

• A hypothetical cause for shallow anterior chamber in malignant glaucoma was developed.
• Laser shrinkage of ciliary processes was effective in five out of six cases.
• Treatment reversed posterior aqueous secretion and restored anterior chamber depth.

Conclusions:

• Relative blockage of forward aqueous flow at the lens equator is a potential inciting factor in malignant glaucoma.
• Laser treatment targeting ciliary processes offers a viable therapeutic option for malignant glaucoma.
• This approach can effectively manage cases refractory to maximal medical therapy.
