Discussion Scleroderma refers to a heterogeneous group of autoimmune fibrosing disorders. The disease can be either “localized” to the skin or “systemic” involving other organs in addition to the skin. Localized scleroderma can be further divided into linear and morphea (localized or generalized patches of atrophic and sclerotic skin lesions).[1] Linear scleroderma is characterized by localized fibrosis of skin, blood vessels, subcutaneous fat, muscle, and sometimes bone. It primarily affects the pediatric population in the first and second decade.[2] When linear scleroderma occurs on the fronto‑parietal scalp, it is referred to as “‘en coup de sabre,” given the resemblance of the skin lesion to the stroke of a sabre.[3] Specific neurological and ophthalmic associations of craniofacial scleroderma have been reported in literature that were all ruled out in our patient. The ophthalmic manifestations in scleroderma may include ptosis, lid induration or tightening, lash loss, motility disorder, keratoconjunctivitis sicca, conjunctival injection and vascular sludging, fornix shortening, iritis, heterochromia iridis, papillitis, retrobulbar pain, enophthalmos, displacement of outer canthus from resorption of orbital bone, and retinal hemorrhages.[2‑5]

Scleroderma is a rare cause of enophthalmos after ruling out other likely differentials of orbital fracture and orbital metastatic breast cancer. The linear scar on the forehead “en coup de sabre” should not be discarded as an innocuous finding rather should aid the examiner in making the correct diagnosis.

A   27‑year‑old male  was referred to us as a case of unilateral glaucoma with corneal haze. Elaborate history taking revealed painless diminution in vision OS for past 18 months and presence of hearing impairment since childhood. Family history was not contributory [Fig. 1].

The best‑corrected visual acuity OD was 6/6 and OS 1/60. Intraocular pressure (IOP) was OD: 12 and OS: 18 mmHg (on two topical medications) and both eyes had normal corneal sensations. Slit lamp showed OD to be apparently normal while OS demonstrated diffuse corneal haze  [Fig.  2]. There

were no keratic precipitates or corneal vascularization, and further clinical evaluation was not possible due to media haze. Due to diagnostic dilemma, we re‑evaluated the fellow eye to look for any clue. To our surprise, on specular reflection, the apparently normal fellow eye showed enlarged endothelial cells  [Fig.  3]. Specular microscopy of OD showed 650  cells/ mm2 and co‑efficient of variation 38. Hexagonality% could not be picked up, but the picture was suggestive of increased polymorphism  [Fig.  3]. The specular count of OS was not capturable due to corneal edema. Anterior segment OCT of both eyes showed increased pachymetry, OD: 690 µ and OS:

850 µ (corneal edema) [Fig. 4]. Confoscan of the fellow normal eye confirmed polymegathism [Fig. 3]. Being a bilateral endothelial disease at this young age, a diagnosis of congenital hereditary endothelial dystrophy (CHED)[1] was made. Pure tone audiometry was performed which showed moderate sensorineural hearing loss, implying the diagnosis of the “Harboyan syndrome”.[2] The patient was then advised to stop the topical glaucoma medications one by one under monitoring, even after which the IOP remained within normal range. The patient was started on topical hypertonic saline and registered for endothelial keratoplasty.

Conclusion A comprehensive work‑up of both eyes is essential before prematurely concluding at the diagnosis, to avoid redundant patient mismanagement.

Clinical examination revealed a nasal corneal perforation with iris tissue prolapse [Fig. 1, yellow arrow]. To further delineate the extent of the corneal perforation and associated anterior segment changes, integrated optical coherence tomography  (iOCT) was used. It showed corneal wound gaping for entire corneal thickness from the paracentral region to the periphery of the cornea. Within the gaping, prolapsing hyperreflective tissue was made out in continuity with the iris tissue onto the surface of the epithelium, suggestive of iris tissue [Fig. 2a]. The margins from endothelium to the

Following surgery, the iOCT increased corneal thickness due to stromal edema with well‑opposed margins [Fig. 2c and d]. The endothelium on either side of the wound showed a good continuity. Similarly, the stroma and the epithelium showed perfect opposition without any intervening residual iris tissue or any tissue loss.

Discussion The iOCT mainly helps in better intraoperative understanding of the corneal wound‑related problems and the cataract and
