Corneal Hydrops

Acute corneal hydrops is a pathological condition which clinically presents by marked corneal edema developing due to a break in Descemets membrane. Background. To analyze the results of diagnosis and treatment in patients with acute corneal hydrops. Materials and methods. 42 patients (47 eyes) suffering from acute corneal hydrops were included in the study. This condition appeared on both eyes simultaneously or sequentially in 5 patients. Mean age was 28.7 10.1 years (from 19 to 54 years), 31 men, 11 women. In case of complications or inefficacy of medical therapy surgical procedures were performed: 10% gas (C3F8, SF6) injection into the anterior chamber, amniotic membrane transplantation, partial lamellar keratoplasty, DALK, PKP. Results. Duration of corneal ectasia before acute hydrops occurrence was 12.6 4.6 years. Disease was not diagnosed before in 11.9%. Corneal thickness varied from 692 98 m in focal hydrops to 1200 220 m in total hydrops. Area of edema, height of Descemet detachment and gap between break margins were significantly above in cases of subtotal and total hydrops compared with focal and partial hydrops (2, p 0,001). Injection of 10% gas (C3F8, SF6) in the anterior chamber allowed to significantly accelerating the resolution of this condition in cases of subtotal and total hydrops. Conclusion. Analysis of this case series showed the feasibility of a differentiated approach in the treatment of acute corneal hydrops depending on its severity.

Abstract Purpose To evaluate the clinical effects of deep anterior lamellar keratoplasty (DALK) using a single graft after epikeratophakia for the treatment of acute corneal hydrops. Methods This novel surgical procedure was performed on seven eyes of seven patients between 2019 and 2020. The procedure combines a first-stage surgery of epikeratophakia with intracameral sterile air injection and a second-stage surgery of DALK using the same corneal graft for both procedures. Main outcome measures included pre- and postoperative best-corrected visual acuity (BCVA) and anterior segment optical coherence tomography (AS-OCT) parameters. Corneal transparency, neovascularization and epithelization were observed at the 1-year follow-up. Results Corneal edema resolved rapidly in six of the seven cases. The group mean central corneal thickness was significantly reduced from baseline at 1 day, 1 week, 1 month, and 2 months after the first-stage surgery, respectively (P < 0.0001). At a mean of 2.1±0.7 months after the first-stage surgery, DALK was successfully performed in all cases. Six months later, the central corneal thickness was 611±31 µm and the thickness of the recipient’s residual stroma bed was 20±6 µm at the central corneal area. LogMAR BCVA was improved from 1.74±0.34 at baseline to 0.20±0.11 after DALK (P < 0.0001). No postoperative complications appeared in our case series during one years of observation. Conclusion A novel curative effect was found in the treatment of acute corneal hydrops with epikeratophakia followed by DALK using the same corneal graft.

Purpose: To report an unusual presentation of pellucid marginal degeneration (PMD) and its management by using air injection and tension sutures. Case Report: We report 2 cases with a history of acute pain and loss of vision. Examination revealed hydrops at the 6-9 o'clock meridian with Descemet's membrane detachment and tear at the same area and advanced PMD in the other eye. Discussion: Air injection with suturing to treat the hydrops in PMD and crescentic excision with lamellar grafting instead of lamellar keratoplasty lead to better results than conservative management. Conclusion: Corneal hydrops and perforation in patients with PMD is a rare presentation and can be managed by tension sutures and air injection.

Clinical And Pathological Features

Background: To investigate the hypothesis that cases of arteritis similar to thromboangiitis obliterans (TAO) and associated with the use of cannabis were caused by cannabis or THC (dronabinol), or that cannabis use is a co-factor of TAO. Patients and methods: A systematic review on case reports and the literature on so-called cannabis arteritis, TAO, and cardiovascular effects of cannabinoids was conducted. Results: Fifteen reports with 57 cases of an arteritis associated with the use of cannabis and two additional case series of TAO, in which some patients also used cannabis, were identified. Clinical and pathological features of cannabis-associated arteritis do not differ from TAO and the major risk factor of TAO, tobacco use, was present in most, if not in all of these cases. The proposed pathophysiological mechanisms for the development of an arteritis by cannabis use are not substantiated. Conclusions: The hypothesis of cannabis being a causative factor or co-factor of TAO or an arteritis similar to TAO is not supported by the available evidence. The use of the term “cannabis arteritis” should be avoided until or unless more convincing scientific support is forthcoming.
