Reversible cataracts in diabetes mellitus
Journal of the American Optometric Association
|August 1, 1994
Summary
Diabetic cataracts, a rare complication of diabetes mellitus, can rapidly develop and resolve spontaneously. This case highlights reversible cataracts linked to blood sugar fluctuations and insulin therapy.
Area of Science:
- Ophthalmology
- Endocrinology
- Diabetology
Background:
- True diabetic cataracts are rare and infrequently reported.
- Characterized by rapid onset, punctate or stellate opacities, and potential resolution without intervention.
- This case report details reversible cataracts as a complication of diabetes mellitus.
Observation:
- A 52-year-old male presented with sudden visual disability and glare 5 days after initiating insulin therapy for hyperglycemia.
- A complete ophthalmic examination was performed, and the patient was monitored for 3 months.
- The patient was diagnosed with acute posterior subcapsular cataracts secondary to diabetes mellitus.
Findings:
- Lens opacities resolved spontaneously within 7 weeks without intervention.
- A transient hyperopic refractive change was also observed during this period.
- The resolution of cataracts and refractive changes occurred within the 3-month monitoring period.
Implications:
- Transient diabetic cataracts are linked to altered lens hydration due to rapid blood sugar changes.
- Swelling of lens fibers, caused by biochemical shifts, leads to cataract formation and transient hyperopia.
- This condition demonstrates that diabetic cataracts can be reversible, with stabilization typically occurring within 3 months.
