Hypotony maculopathy.

Area of Science:

• Ophthalmology
• Retinal Diseases
• Glaucoma Surgery Complications

Background:

• Hypotony maculopathy, described by Dellaporta in 1954, typically follows antiglaucoma surgery or eye injuries.
• Characterized by hypotony and fundus abnormalities like papilledema, vascular tortuosity, and chorioretinal folds.
• Scleral collapse leads to choroidal and retinal redundancy, causing wrinkling and radial retinal folds around the fovea.

Purpose of the Study:

• To review the definition, underlying mechanisms, clinical presentation, and treatment strategies for hypotony maculopathy.
• To highlight the importance of timely diagnosis and intervention for hypotony maculopathy.
• To discuss factors associated with the development of hypotony maculopathy.

Main Methods:

• Literature review of hypotony maculopathy.
• Analysis of clinical findings and pathological mechanisms.
• Summary of current treatment approaches for hypotony maculopathy.

Main Results:

• Hypotony maculopathy occurs in up to 20% of glaucoma filtering surgeries, potentially increasing with antimetabolite use.
• Associated factors include young age, myopia, primary surgery, systemic conditions, and elevated preoperative intraocular pressure (IOP).
• Treatment aims to elevate IOP, reverse scleral bowing, and improve visual acuity.

Conclusions:

• Successful treatment hinges on accurate cause identification and prompt intervention to prevent permanent macular damage.
• Delayed normalization of IOP can lead to irreversible chorioretinal changes and vision impairment.
• Understanding the pathophysiology is key to managing hypotony maculopathy effectively.
