[5 years' experience in the treatment of neovascular glaucoma using cryocoagulation. I. Development of intraocular...

The authors evaluate the results of reduction of intraocular pressure in 38 eyes with neovascular glaucoma after a cryosurgical operation. In 12 eyes they used cyclocryocoagulation as an independent method, in 26 eyes transscleral panretinal cryocoagulation combined with cyclocryocoagulation in one session. The achieved results indicate, that intraocular pressure in neovascular glaucoma can be influenced more readily by a combined cryosurgical operation than by cyclocryocoagulation alone. When using transscleral panretinal cryocoagulation in combination with cyclocryocoagulation, they achieved after operation an intraocular pressure under 26 mm Hg within 3 days after operation in 50%, within 10 days in 76.9%. They observed a subsequent rise of the intraocular pressure in 15%. Hypotension developed in 30.8%. A quite high percentage of eyes with extreme hypotension and subsequent atrophy of the bulbus with amourosis (27%) is according to the authors due to too extensive cyclocryocoagulation.
