| Case Report|| |
A 15-year-old male presented with sudden diminution of vision in the right eye following blunt trauma with a wooden stick. On examination, the visual acuity (VA) was finger counting 2 m, intraocular pressure (IOP) was 18 mm Hg, and slit lamp biomicroscopy showed dispersed hyphema in the anterior chamber. After 3 weeks of medical management, hyphema resolved, VA improved to 20/60, and IOP was 30 mm Hg. Gonioscopy revealed angle recession in 6 o'clock hours in inferior quadrant (3 o'clock to 9 o'clock). A diffuse slit lamp illumination showed a demarcated semicircular cataract in the inferior part of the lens [Figure 1]a with a broad slit showing backward deviation of the beam at the level of posterior capsule (PC) [Figure 1]b.

Focal slit illumination showing backward deviation of slit beam at the level of posterior capsule in the area of cataract (white arrows), increased opacification of posterior capsule at the margins of cataract, and wrinkling of posterior capsule at the superior margin (black arrows). (c) Diffuse illumination showing total cataract and visible lens edge in the inferior 2 o'clock hours|

Further evaluation with anterior segment optical coherence tomography (ASOCT) showed an ectatic PC in the area of demarcated cataract [Figure 2] and a provisional diagnosis of posterior lenticonus was thus made. After 2 weeks on antiglaucoma agents, the patient presented with total cataract [Figure 1]c when phacoemulsification with intraocular lens implantation in bag was carried out. Intraoperatively, concentric area of fibrosis was noted in the inferior part of PC. After surgery, unaided VA was 20/30 and ASOCT showed PC folds [Figure 3].

| Discussion|| |
Isolated PC rupture following trauma may resemble posterior lenticonus. After trauma, lenticular epithelium becomes hyperplastic, undergoes fibrous metaplasia, and starts migrating along the PC in an attempt to heal the defect which not only manifests as fibrosed margins of PC break but may also migrate over the intact anterior vitreous phase, thus giving a false impression of an intact PC in some cases.,
| Conclusion|| |
Our patient had sustained blunt trauma. Presence of wrinkling of PC along the superior margin and fibrosed margins gave an impression of PC break with anterior vitreous phase opacification. However, ASOCT confirmed the diagnosis of posterior lenticonus.
