Background and objectiveCorneal transplants are associated with multiple well-known complications, one of them being wound dehiscence. It results in unfavorable outcomes, such as ocular structure damage, graft failure, repeated surgeries, and possibly a poor prognosis in terms of vision quality. Although the wound site may appear well-healed clinically, as the strength at the graft-host junction is weak, the site is susceptible to dehiscence. Wound dehiscence can be secondary to suture removal and/or trauma. In this study, we assessed the incidence of wound dehiscence secondary to trauma following corneal transplant and evaluated its occurrence in terms of patient age, type of corneal transplant performed, duration between corneal transplantation and wound dehiscence, mechanism of injury, and final outcome.MethodsThis was a case series that included all patients who suffered from wound dehiscence secondary to trauma post-corneal transplant between January 1, 2009, and December 31, 2019, at Hospital Kuala Lumpur.ResultsA total of 492 patients underwent corneal transplant surgery during the 10-year study period. Based on specified inclusion and exclusion criteria, only 13 patients were eligible for inclusion in this study. The incidence of wound dehiscence secondary to trauma post-penetrating keratoplasty (PK) was low (2.64%). Twelve patients had undergone PK, while one patient had undergone deep anterior lamellar keratoplasty (DALK). Blunt ocular trauma post-transplant can cause wound dehiscence regardless of patient age and duration post-corneal transplantation. Males are at a higher risk as their active lifestyle contributes to higher exposure to ocular injury.ConclusionAs corneal transplant patients are at life-long risk of wound dehiscence post-transplant, they must be counseled about this possible risk and the need to take adequate precautions in their daily lives. Based on our findings, the use of newer technologies and partial- rather than full-thickness corneal transplants should be explored further.

This report aims to raise awareness among ophthalmologists about gonococcal keratitis, which may present with peripheral corneal thinning and ulceration accompanied by mucopurulent discharge. A high index of suspicion facilitates early diagnosis, timely intervention, and improved visual outcomes. We describe three cases: a 49-year-old male presenting with right eye redness, vision loss, and purulent discharge from both the eye and urethra, whose examination revealed peripheral corneal thinning with perforation and iris plugging; a 28-year-old healthy male with a two-day history of decreased visual acuity, photophobia, and purulent discharge in the left eye, with findings of a corneal perforation at the 10 o'clock position and peripheral thinning; and a 19-year-old male reporting seven days of right eye redness, purulent discharge, lid swelling, and vision loss, preceded by a five-day history of urethral discharge and dysuria, with examination showing peripheral corneal thinning and ulceration with corneal perforation. Corneal swabs from all three patients tested positive for , confirming gonococcal keratoconjunctivitis leading to corneal perforation. They were treated with intravenous ceftriaxone (2 g daily for 14 days) and topical antibiotics, and all subsequently underwent corneal transplantation. In conclusion, gonococcal keratoconjunctivitis is a rapidly progressive condition that can result in corneal perforation, endophthalmitis, and blindness, underscoring the critical need for early recognition and prompt ophthalmologic referral.

To evaluate the corneal topographical changes in vernal keratoconjunctivitis (VKC) subjects using OCULUS Pentacam. This was a cross-sectional study. VKC patients and normal subjects who fulfilled the inclusion and exclusion criteria were recruited by convenience sampling into the study. Subjects underwent a best-corrected visual acuity measurement with a Snellen chart, retinoscopy, and corneal topography (OCULUS Pentacam®), followed by anterior segment and fundus examination and intraocular pressure measurement. Data were collected and analyzed using SPSS version 26.0 for Windows (SPSS Inc. Chicago, IL, USA). A p-value <0.05 was considered statistically significant. A total of 78 eyes of 43 VKC patients and 84 eyes of normal subjects were included in the study. Most of the VKC subjects were Malay males aged 10 years or less. A majority (71.8%) had palpebral VKC of five years duration or less (57.7%) and presented between the ages of six and 10 years (44.9%). Central corneal curvature and astigmatism were significantly higher in VKC subjects compared to the normal population (p < 0.05). The minimal pachymetry was significantly lower with a longer duration of VKC (p < 0.05). Older age of presentation of VKC was associated with higher central corneal curvatures and thinner minimal pachymetry (p < 0.05). There was no association between the type of VKC and corneal topography changes. The prevalence of keratoconus and subclinical keratoconus among VKC subjects was 10.3% and 11.5%, respectively. Longer duration and older age of presentation of VKC are associated with significant corneal topographical changes, thus exposing them to a higher risk of the future development of keratoconus.

Orbital cellulitis is a sight- and life-threatening condition. Prompt diagnosis and immediate intervention are required. We report a case of fatal odontogenic orbital cellulitis complicated with intracranial abscesses in a 55-year-old gentleman. The patient presented with painful swelling of the left eye associated with reduced eye movement, blurry vision, and a headache. There was generalized periodontitis. Initial imaging was suggestive of left eye orbital cellulitis with intracranial abscess, and intensive systemic antibiotic therapy was initiated. After six weeks of antibiotic therapy, there was an improvement in ocular signs and symptoms. However, the patient developed signs of meningism with a persistent fever. Serial brain imaging demonstrated worsening intracranial abscesses. The patient died eight weeks after the initial onset of presentation. This case emphasized that brain abscesses could be a fatal complication of odontogenic orbital cellulitis. A high index of suspicion is important in diagnosing orbital cellulitis and its complications. Early consideration of surgical intervention is necessary in cases not responding to antibiotic therapy.

Epithelial conjunctival malignancies are one of the most prevalent ocular surface tumors. Primary basal cell carcinoma (BCC) of the conjunctiva is extremely rare. We report the case of a 67-year-old Indian gentleman who presented with a fleshy conjunctival lesion for one year on his right eye. Examination revealed a lightly pigmented conjunctival mass adjacent to the limbus. The surface was irregular and non-ulcerated with few feeder vessels. The working diagnosis was ocular surface squamous neoplasia (OSSN). A wide excisional biopsy using the no-touch technique and double-freeze-thaw cryotherapy to the conjunctival margins was performed. The bare scleral area was covered with an amniotic membrane. Histopathological examination revealed a basaloid cell neoplasm favoring BCC, and a tumor-free margin was achieved. Three cycles of topical mitomycin-C 0.02% were prescribed as adjunct chemotherapy postoperatively. There was no evidence of recurrence three months after treatment. The primary BCC of the conjunctiva is unusual and can resemble OSSN. Therefore, it should be considered in the differential diagnosis of patients presenting with atypical features of OSSN.
