Abstract:
To report a case of recurrent hypotony and choroidal effusion following trabeculectomy.
Observations:
A 70 year old male with advanced pseudoexfoliation glaucoma in both eyes underwent trabeculectomy in the left eye. Initially intraocular pressure (IOP) was controlled without topical therapy, but dorzolamide-timolol and brimonidine were added when IOP elevated above target. Aqueous suppressant glaucoma medications were thought to cause three episodes of hypotony resolving with discontinuation of these medications. Conclusions and Importance: Although hypotony and choroidal detachment associated with the use of aqueous suppressants is rare, it should be considered in patients with hypotony of unclear etiology following a glaucoma filtering procedure. Aqueous suppressants should be discontinued and it is recommended that the glaucoma drop regimen be switched to non-aqueous suppressants in patients with these findings.

Glomerular Filtration: Net Filtration Pressure
GBHP, with an average value of 55 mmHg, promotes filtration by pushing water and solutes through the filtration membrane. This is balanced by two opposing forces: CHP, a "back pressure" exerted against the filtration membrane by fluid already in the capsular space and renal...

Pleural Effusion II: Symptoms and Management
A pleural effusion is the abnormal collection of fluid between the parietal and visceral pleura layers of tissue that form the lining of the lungs and chest cavity. It can occur independently or due to surrounding parenchymal diseases, such as infection, malignancy, or inflammatory conditions.
