Cyclic presentation of central macular oedema
Acta Ophthalmologica Scandinavica
|May 20, 1998
Summary
This case study highlights a young woman with pars planitis experiencing fluctuating vision due to cystoid macular edema linked to her menstrual cycles. This cyclical pattern of macular edema is unprecedented in medical literature.
Area of Science:
- Ophthalmology
- Immunology
Background:
- Pars planitis is a form of intermediate uveitis characterized by inflammation of the ciliary body and peripheral retina.
- Cystoid macular edema (CME) is a common complication of various ocular inflammatory conditions, leading to vision loss.
Observation:
- A young female patient presented with unilateral pars planitis.
- She reported recurrent visual disturbances, specifically fluctuating central vision loss.
- These visual fluctuations correlated with her monthly menstrual cycles.
Findings:
- The patient exhibited cystoid macular edema (CME) in the affected eye.
- The CME showed a distinct cyclical pattern, worsening and improving with her menstrual cycle.
- This menstrual cycle-associated fluctuation of CME in pars planitis is a novel observation.
Implications:
- This case suggests a potential hormonal influence on the inflammatory processes in pars planitis and associated CME.
- Further research into hormonal modulation could offer new therapeutic strategies for managing CME in uveitis.
- Understanding this link may improve diagnostic and management approaches for patients with cyclical visual symptoms.

Glaucoma: Overview
Glaucoma is an eye condition characterized by increased intraocular pressure that damages the retina and optic nerve, leading to irreversible blindness if left untreated. The human eye has various components, including the cornea, iris, pupil, lens, and optic nerve. Aqueous humor is secreted by the epithelium of the ciliary body in the posterior chamber and flows through the trabecular meshwork and canal of Schlemm, maintaining normal intraocular pressure. The trabecular meshwork and the canal...
Angle Closure Glaucoma: Treatment
Angle-closure glaucoma, or closed-angle glaucoma, is an eye condition where the iris bulges out and blocks the iridocorneal angle, resulting in a buildup of aqueous humor and increased intraocular pressure. Immediate medical attention is necessary due to the sudden onset of symptoms. The treatment for angle-closure glaucoma includes short-term and long-term approaches. Short-term treatment involves using eye drops like pilocarpine to lower intraocular pressure by increasing aqueous humor...
Diabetic Retinopathy
DefinitionDiabetic retinopathy is a microvascular complication of diabetes affecting the retinal blood vessels.Risk FactorsDiabetic retinopathy is present in almost all individuals with type 1 diabetes and more than 60% of those with type 2 diabetes after two decades of disease.The risk increases with poor glycemic control, hypertension, dyslipidemia, smoking, pregnancy, and puberty.Although cataracts and glaucoma are also more frequent in people with diabetes, retinopathy remains the leading...
