Weather as a possible risk factor for massive ocular decompression retinopathy: A case report

Area of Science:

• Ophthalmology
• Environmental Medicine
• Retinal Diseases

Background:

• Studies link weather phenomena to cardiovascular and cerebrovascular events.
• Acute primary angle closure can lead to rapid intraocular pressure reduction.
• The case occurred during a period of high temperatures and strong Foehn wind (halny).

Purpose of the Study:

• To report a case of ocular decompression retinopathy secondary to acute intraocular pressure reduction.
• To explore the potential influence of environmental factors on this condition.

Main Methods:

• A case report of a 56-year-old male with acute primary angle closure.
• The patient developed severe ocular decompression retinopathy with massive prefoveal subhyaloid hemorrhage after pharmacological treatment.
• Surgical intervention (vitrectomy) was performed, leading to visual acuity improvement.

Main Results:

• The patient experienced severe ocular decompression retinopathy with massive premacular hemorrhage.
• Visual acuity improved to baseline following vitrectomy.
• The event coincided with specific weather conditions (high temperatures, halny wind).

Conclusions:

• Abrupt intraocular pressure reduction is a causative factor for ocular decompression retinopathy.
• Environmental factors, such as the halny wind, may significantly influence the development of this condition.
