Diabetic ketoacidosis with retinal tear
Annals of Ophthalmology
|December 1, 1977
Summary
Diabetic ketoacidosis can cause changes in eye anatomy. Vitreous humor volume decreased during treatment, potentially leading to retinal tears.
Area of Science:
- Ophthalmology
- Endocrinology
- Biometry
Background:
- Diabetic ketoacidosis (DKA) is a serious complication of diabetes mellitus.
- DKA can lead to significant dehydration and metabolic disturbances.
- Ocular changes associated with DKA are not fully understood.
Observation:
- Ultrasonic biometry was employed to monitor axial vitreous length in a patient with DKA.
- Measurements were taken during the acute phase and upon resolution of the DKA episode.
- A horseshoe-shaped retinal tear was noted post-discharge.
Findings:
- Axial vitreous length increased significantly (p < 0.05) as DKA resolved, from 14.09 mm to 14.26 mm.
- Vitreous volume changes during DKA treatment showed similarities to osmotic agent-induced changes in rabbits.
- The observed vitreous changes suggest a potential mechanism for retinal tear formation.
Implications:
- Severe dehydration in DKA may cause vitreous compartment shrinkage.
- Vitreoretinal traction resulting from vitreous shrinkage could precipitate retinal tears.
- This case highlights a potential, previously unrecognized ocular complication of DKA.
