Rapidly Progressive Central Scotoma Following Blunt Trauma in a 29-Year-Old Athlete
01. Clinical History
A 29-year-old male squash athlete presented to the emergency eye clinic 3 days after sustaining a direct blunt injury to the right eye by a high-velocity squash ball. He reported immediate onset of central blurry vision, photopsia, and an enlarging dark spot in his visual axis. He had no prior ophthalmic history and was not wearing protective eyewear. No systemic illnesses or regular medications.
02. Examination
Best Corrected Visual Acuity (BCVA): 20/200 OD (Right Eye), 20/20 OS (Left Eye).
Intraocular Pressure (IOP): 14 mmHg OD, 15 mmHg OS.
Anterior Segment (OD): Mild conjunctival ciliary flush, clear cornea, 1+ micro-hyphema in the inferior angle, pupil round and reactive with a subtle relative afferent pupillary defect (RAPD) on the right.
Fundus Examination (OD): Clear media, healthy optic disc, commotio retinae (Berlin's edema) along the inferior arcade, and a well-circumscribed, round, red full-thickness foveal defect with a surrounding cuff of subretinal fluid.
03. Images & Investigations
04. Clinical Questions
- What is the primary pathophysiological mechanism causing traumatic macular hole formation?
- What is the role of conservative observation versus prompt surgical intervention?
- What SD-OCT prognostic markers predict spontaneous closure versus non-closure?
05. Discussion
Traumatic macular holes (TMHs) occur secondary to sudden anteroposterior vitreous traction and violent equatorial expansion following mechanical globe deformation. Unlike idiopathic senile macular holes, traumatic holes carry a well-documented rate of spontaneous closure, ranging between 10% and 40%, particularly in young patients with small hole diameters (< 250 µm) and lack of complete posterior vitreous detachment.
06. Definitive Diagnosis
Stage 3 Traumatic Full-Thickness Macular Hole with Commotio Retinae (Right Eye).
07. Management & Clinical Decision
A close observational protocol was initiated for 8 to 12 weeks. Topical anti-inflammatory agents were administered for the anterior segment hyphema. In the absence of spontaneous closure by week 10, the patient was scheduled for 25-gauge pars plana vitrectomy, inverted internal limiting membrane (ILM) flap transposition, and sulfur hexafluoride (SF6) gas endotamponade.
08. High-Yield Learning Points
- Traumatic macular holes possess higher rates of spontaneous closure than idiopathic holes.
- A trial of observation for 2 to 3 months is acceptable if no progressive retinal detachment or secondary pathology is observed.
- Inverted ILM flap techniques significantly elevate anatomic and functional closure rates when surgery is required.
