Abstract: A 15-year-old female child with history of bilateral poor vision since childhood presented with sudden onset pain, photophobia, and diminution of vision OD for 10 days. Visual acuity was hand motion OD and 1/60 OS. Slit lamp examination revealed microcornea OU with multiple intrastromal fluid clefts OD and an irregular cornea and iridofundal coloboma OS. A clinical diagnosis of acute corneal hydrops OD was made, and the child was subjected to intraoperative optical coherence tomography guided intrastromal flui… Show more

“…[1][2][3] It may either occur as an isolated condition or be associated with short axial length or uveal coloboma. 4,5 Compared with normal-sized corneas, MCs possess specific parameters. For instance, increased central corneal thickness (CCT) and endothelial cell density (ECD) have been reported in patients with MC associated with uveal coloboma.…”

Purpose:The purpose of this study was to evaluate the features of and relationships among corneal diameter, central corneal thickness (CCT), endothelial cell density (ECD), and corneal refractive properties in cases of microcornea (MC) with normal axial length.Methods:We included 22 patients (35 eyes) with MC and cataracts and 41 patients (48 eyes) with isolated cataracts as age-matched controls. They were divided into patients with MC younger than 18 years (MC-child), patients with MC 18 years or older (MC-adult), children with congenital cataracts (CCs), and adults with senile cataracts (SCs). Corneal diameter, axial and anterior chamber length, and keratometry were measured; central corneal endothelial cell imaging was performed.Results:The mean horizontal corneal diameter was 7.71 ± 1.51 and 8.78 ± 0.52 mm in MC-child and MC-adult groups, respectively, and 11.89 ± 0.59 and 11.52 ± 2.42 mm in child and adult controls, respectively. The mean CCT was 641.26 ± 63.37 (MC-child) and 617.38 ± 45.40 mm (MC-adult), and 554.92 ± 34.64 (CC) and 551.58 ± 28.47 mm (SC). The mean ECD was 2898.47 ± 443.90 (MC-child) and 2825.81 ± 484.65 cells/mm2 (MC-adult), and 3155.13 ± 372.67 (CC) and 2749.33 ± 399.63 cells/mm2 (SC). The average keratometry was 44.22 ± 3.14 D (MC-child) and 43.86 ± 2.59 D (MC-adult), and 44.19 ± 1.44 D (CC) and 43.94 ± 1.34 D (SC).Conclusions:Patients with MC and normal axial length possess specific parameters, including significantly smaller corneal diameter and thicker CCT than the patients in the control groups. There were no significant differences in ECD and average keratometry. These parameters should be taken into account in the follow-up and treatment.

AIM: To evaluate the efficacy and safety of full-thickness sutures combined with intracameral air injection (FTS-AI) versus pre-Descemet’s membrane sutures combined with intracameral air injection (PDS-AI) in the management of acute corneal hydrops in keratoconus. METHODS: The research included 8 patients (8 eyes) suffering from acute corneal hydrops caused by keratoconus. Four patients were randomly assigned to FTS-AI. And the other four were randomly assigned to PDS-AI. Corneal oedema, visual acuity, corneal thickness were assessed during follow-up. RESULTS: The demographics, preoperative duration of symptoms and severity of corneal hydrops between the two groups were not significantly different. The mean corneal oedema resolution time after FTS-AI and PDS-AI were 11±1.15 and 15±1.41d, respectively (P=0.005). The maximum corneal thickness of the scarred region decreased in both groups at one week postoperatively (P<0.05). No obvious difference was found in the mean maximal corneal thickness between the two groups postoperatively. The BCVA improved significantly after FTS-AI and PDS-AI at three months postoperatively. No obvious difference was found in the BCVA after FTS-AI and PDS-AI at three months postoperatively. CONCLUSION: FTS-AI and PDS-AI are safe and effective therapies to accelerate the resolution of corneal oedema in acute corneal hydrops secondary to keratoconus. Despite faster resolution of corneal oedema in the FTS-AI group, we recommend PDS-AI to avoid potential endothelium cell damage.

Background: Optical coherence tomography (OCT) has recently been introduced in the operating theatre. The aim of this review is to present the actual role of microscope-integrated optical coherence tomography (MI-OCT) in ophthalmology. Method: A total of 314 studies were identified, following a literature search adhering to the preferred reporting items for systematic reviews and meta-analyses (PRISMA) guidelines. After full-text evaluation, 81 studies discussing MI-OCT applications in ophthalmology were included. Results: At present, three microscope-integrated optical coherence tomography systems are commercially available. MI-OCT can help anterior and posterior segment surgeons in the decision-making process, providing direct visualization of anatomic planes before and after surgical manoeuvres, assisting in complex cases, and detecting or confirming intraoperative complications. Applications range from corneal transplant to macular surgery, including cataract surgery, glaucoma surgery, paediatric examination, proliferative diabetic retinopathy surgery, and retinal detachment surgery. Conclusion: The use of MI-OCT in ophthalmic surgery is becoming increasingly prevalent and has been applied in almost all procedures. However, there are still limitations to be overcome and the technology involved remains difficult to access and use.
