Summary
Transscleral cyclopexy with diode laser effectively treated persistent ocular hypotony and vision loss after blunt eye trauma. This laser treatment resolved post-traumatic cyclodialysis unresponsive to medical management.
Area of Science:
- Ophthalmology
- Trauma Surgery
Background:
- Persistent ocular hypotony and vision loss following blunt eye trauma can significantly impair visual function.
- Traumatic cyclodialysis, a ciliochoroidal detachment, often leads to hypotony and requires effective management.
Observation:
- A 28-year-old male presented with severe ocular hypotony (4 mmHg), reduced visual acuity (0.4), optic disc edema, and macular chorioretinal folds after blunt left eye trauma.
- Optical coherence tomography revealed significant foveal thickening (326 microns), and ultrasound biomicroscopy showed nasal iris desinsertion and a 360-degree choroidal detachment.
Findings:
- Conservative treatment failed to resolve the hypotony.
- Transscleral cyclopexy with contact diode laser was performed 10 months post-trauma.
- One year after laser treatment, visual acuity improved to 1.0, intraocular pressure normalized to 14 mmHg, and foveal thickness reduced to 240 microns.
Implications:
- Transscleral cyclopexy with diode laser presents a viable therapeutic option for recalcitrant post-traumatic cyclodialysis.
- This approach can restore visual acuity and normalize intraocular pressure in cases unresponsive to medical therapy.
