Rubeotic glaucoma

Area of Science:

• Ophthalmology
• Vascular Biology
• Retinal Diseases

Background:

• Theories of causation for rubeosis and thrombotic glaucoma are reviewed.
• Retinal anoxia was identified as a primary cause of rubeosis iridis and subsequent glaucoma in 1954.
• Rubeosis iridis and thrombotic glaucoma are serious ocular conditions often leading to vision loss.

Purpose of the Study:

• To review the literature on the causation of rubeosis and thrombotic glaucoma.
• To evaluate the effectiveness of retinal destruction methods in preventing these conditions.
• To discuss future directions for preventing thrombotic glaucoma.

Main Methods:

• Literature review of theories on causation of rubeosis and thrombotic glaucoma.
• Analysis of historical treatment attempts, including surface diathermy and cryotherapy.
• Evaluation of outcomes from retinal destruction procedures in 18 eyes.

Main Results:

• Retinal anoxia is a key factor leading to rubeosis and glaucoma.
• Retinal destruction techniques (diathermy, cryotherapy) were employed to prevent rubeosis.
• While visual results were poor, none of the 18 treated eyes required enucleation.

Conclusions:

• Thrombotic glaucoma, stemming from retinal anoxia and rubeosis, presents a significant clinical challenge.
• Current destructive retinal treatments offer limited visual benefit but can prevent irreversible damage like enucleation.
• Improved prediction and therapeutic strategies are crucial for making thrombotic glaucoma a preventable condition.
