Multi-drug resistant Klebsiella-induced corneal ulcer following pterygium surgery: a case report.

BACKGROUND: Management of pterygium is dependent on the grading of pterygium and its clinical presentation (inflamed or quiescent), and surgical excision is the final choice of treatment for the pterygium extending beyond the limbus. Infectious keratitis is one of the most commonly reported complications in recent years. To the best of our knowledge, Klebsiella keratitis after pterygium surgery has not been described in the current literature. Here, we report a patient with corneal ulcer formation following pterygium surgical excision. CASE PRESENTATION: A 62-year-old woman presented with complaints of pain, blurred vision, photophobia and redness in her left eye for a month. She had a history of pterygium surgical excision two months ago. Slit-lamp examination showed conjunctival congestion, a central whitish corneal ulcer with a central epithelial defect, and hypopyon. Corneal scraped sample revealed multidrug resistant (MDR) Klebsiella pneumonia and the strain was found to be sensitive to cefoxitin and ciprofloxacin. Intracameral cefuroxime (1 mg/0.1 mL) injection, fortified cefuroxime ophthalmic suspension (50 mg/mL) and moxifloxacin ophthalmic suspension (0.5%) were successfully administered to control the infection. Since residual central stromal opacification remained persistent, final visual acuity did not improve beyond finger counting at two meters. CONCLUSIONS: Klebsiella keratitis is a rare and sight-threatening complication following pterygium excision. This report emphasizes the importance of close follow-up examination following pterygium surgeries.

Evaluation of the Cornea and Anterior Chamber Morphologic Changes After Penetrating Keratoplasty in Patients With Keratoconus.

OBJECTIVES: To evaluate changes of the cornea and anterior chamber after penetrating keratoplasty in eyes with keratoconus. METHODS: Medical records of 68 eyes of 68 patients with keratoconus who experienced penetrating keratoplasty at the Eye Clinic of Dr. Lütfi Kirdar Kartal Research and Training Hospital between 2010 and 2012 were studied. Records were retrospectively evaluated with regard to anterior chamber depth, iridocorneal angle, central corneal thickness, thinnest corneal thickness, maximum keratometric value, and mean keratometric value. Patients who developed complications and required additional surgery were excluded. RESULTS: A total of 68 eyes of 68 patients were included in this study. There were 40 (58.8%) male and 28 (41.2%) female patients. The mean age was 24.5±8.19 years (range: 11-42 years). The graft diameter was 7.5 mm and the recipient bed diameter was 7.0 mm in all patients. The preoperative anterior chamber depth decreased from 3.92±0.47 mm to 3.01±0.55 mm (23% decrease). No significant postoperative change was observed in the mean iridocorneal angle values. Keratometric values decreased by 30% and corneal thickness increased by 50% (P<0.001 for both). CONCLUSION: Anterior chamber depth decreased significantly, but no change was observed in iridocorneal angle after penetrating keratoplasty in patients with keratoconus. Also, a decrease in the keratometric values and an increase in corneal thickness were observed. Understanding, estimating, and managing changes in the anterior chamber after penetrating keratoplasty, which induces significant changes in anterior chamber morphology, might increase the success of surgery.

Spontaneous Resolution of Bilateral Bullous Serous Retinal Detachment in Preeclampsia: A Case Report from Somalia.

A 29-year-old preeclamptic postpartum patient with no symptoms of hypertension in her medical history before pregnancy was referred to the ophthalmology outpatient clinic with the complaint of sudden bilateral vision loss. Slit-lamp fundus examination and B-scan ultrasonography showed serous retinal detachment (SRD) in both eyes. She was diagnosed with bullous SRD due to preeclampsia (PE). The patient's fundoscopy findings regressed spontaneously, and visual acuities improved within one month. SRD should be considered in case of vision loss before or after birth in patients with PE, and such patients should undergo retinal examination.

Weighted Comparison of the Corneal Topographic Data in Intracapsular versus Ciliary Sulcus Intraocular Lens Implantation during Phacoemulsification Surgery.

OBJECTIVES: This study aimed to evaluate the preoperative and postoperative changes in corneal topography, intraocular pressure (IOP), and visual acuity in patients who developed posterior capsule rupture during phacoemulsification surgery and simultaneously underwent ciliary sulcus intraocular lens (IOL) implantation and in those with intact capsular integrity who simultaneously underwent intracapsular IOL implantation and to compare these changes within and between the two groups. METHODS: Among the 855 patients, 92 eyes of 69 patients whose corneal topography, IOP, and best-corrected visual acuity (BCVA) were successfully measured were included in the study. Preliminary chamber parameters [horizontal visible iris diameter (HVID), iridocorneal angle, anterior chamber volume (ACV), and anterior chamber depth (ACD)] were measured before and after surgery using a Sirius corneal topography device. RESULTS: The IOL was implanted in the capsular bag in 58 patients and in the ciliary sulcus between the posterior iris and the capsule in 34 patients. In the sulcus IOL group, both BCVA and IOP measurements statistically significantly increased in the postoperative period compared with the preoperative values (p<0.001). As regards postoperative changes between the intracapsular and sulcus IOL groups, no significant difference was found in the changes in HVID (p=0.584), iridocorneal angle (p=0.282), and ACD (p=0.382), whereas the changes in ACV, IOP, and BCVA were statistically significantly different (p=0.020, p<0.001, and p<0.001, respectively). CONCLUSION: While the IOP of the sulcus IOL group significantly increased, that of the intracapsular group significantly decreased. Visual acuity increased in both lens implants, but patients with intracapsular lenses had greater improvement in visual acuity; thus, intracapsular IOL implantation was more advantageous than sulcus IOL implantation.
