[Laser surgery for some forms of secondary posttraumatic glaucoma]

Area of Science:

• Ophthalmology
• Medical Technology

Background:

• Secondary posttraumatic glaucoma presents complex challenges.
• Three specific forms include adhesive glaucoma with anterior-chamber adhesions and goniosynechias, adhesive glaucoma with aphakia-aniridia, and aphakic malignant glaucoma.

Purpose of the Study:

• To evaluate the efficacy of Neodymium-doped Yttrium Aluminum Garnet (Nd:YAG) laser treatment for secondary posttraumatic glaucoma.
• To define the role of laser synechiolysis and hyaloidotomy in managing these conditions.

Main Methods:

• Treatment of 70 patients using the Zeiss Visulas YAG I Nd:YAG laser.
• Application of laser synechiolysis and transpupillary laser hyaloidotomy.

Main Results:

• Laser synechiolysis demonstrated high efficacy in early-stage adhesive glaucoma with anterior-chamber adhesions and goniosynechias.
• Peripheral hyaloidotomy, combined with pharmacotherapy, proved effective in normalizing intraocular pressure.
• The study established the utility of transpupillary laser hyaloidotomy for aphakic malignant glaucoma.

Conclusions:

• Early intervention with laser synechiolysis is crucial for adhesive glaucoma.
• Nd:YAG laser procedures, including hyaloidotomy, are valuable tools in managing complex secondary glaucomas.
• Tailored laser interventions offer effective treatment strategies for specific posttraumatic glaucoma subtypes.
