A 49-year-old gentleman presented with a 1-day history of painful deterioration of vision in his right eye. He was lifting heavy weights just before this visual loss. On examination, his vision was perception of light in that eye, with a medically uncontrollable high intraocular pressure and hyphaema almost completely filling his anterior chamber. An ultrasound performed suggested a working diagnosis of a Valsalva related ‘eight ball’ bleed. After an anterior chamber washout, he had another episode of bleeding three days later. A pars plana vitrectomy was performed and the sample obtained was sent off to the laboratory, revealing a choroidal melanoma. Following enucleation, the histology confirmed a large necrotic spindle cell melanoma, with a haemorrhagic background. Fortunately, no liver metastasis was found. Since his diagnosis 3 years ago, he continues to be followed up in an artificial eye clinic and has regular liver scans under the care of his oncologist.

Abstract Objective This study aims to analyze and compare the postoperative ocular parameters of two different types of implantable contact lenses (ICLs) (for retinal detachment) to provide a clinical reference for vitreoretinal surgery. Methods From March 2016 to March 2021, 24 patients (24 eyes) with rhegmatogenous retinal detachment following ICL implantation at the Eye Center of Taizhou Central Hospital were recruited. Based on the different types of ICL, they were divided into the V4 type ICL implantation group (V4 type group) and v4C type ICL implantation group (v4C type group), with 12 cases (12 eyes) in each group. Both groups were treated with pars plana vitrectomy; differences in postoperative ocular complications between the two groups were compared. Results The postoperative uncorrected and best corrected visual acuity for both groups were significantly higher than those preoperatively (P < 0.001); the same applied to the intraocular pressures (P < 0.05). Fluctuation in intraocular pressure was higher in the V4 group than in the v4C group (P < 0.05). The arch height, measured using anterior segment optical coherence tomography on the first day after operation, was lower in the V4 group than in the v4C group (P < 0.05). There was also no significant difference between the two groups before and after the operation (P > 0.05). Conclusion For patients with V4 type ICL implantation and mesh removal, stimulation of the ciliary body and the risk factors for pupil block caused by ciliary muscle spasm should be reduced as much as possible during pars plana vitrectomy. If postoperative complications such as decreased arch height and increased intraocular pressure occur, the application of compound tropicamide eye drops is an effective method to activate the pupil.

Objective. To evaluate the morphological changes of the anterior segment using ultrasonic biomicroscopy (UBM) imaging in pseudophakic patients who underwent pars plana vitrectomy (PPV) with silicone oil or gas (C3F8) internal tamponade agent injection.Method. This prospective study included pseudophakic patients with planned PPV, divided into two groups according to internal tamponade agent: those in which silicone oil was used (n=27, Group 1) and those in which gas (C3F8) was used (n=24, Group 2). UBM measurements were performed in the supine position before and one week after surgery.Results. In patients of Group 1, postoperative trabecular meshwork-ciliary process distance (T-CPD) and iris-ciliary process distance (I-CPD), according to preoperative values, were found to be statistically significantly reduced, and postoperative mean value of scleral thickness (ST) and intraocular pressure (IOP), according to preoperative value, was found to be statistically significantly increased. In patients of Group 2, postoperative mean values of anterior chamber depth (ACD), ciliary body thickness (CBT), T-CPD, I-CPD, and IOP, according to preoperative values, were found to be statistically significantly reduced. Preoperatively, in Group 2 patients, according to Group 1 patients, TIA and IOP were found to be statistically significantly increased. Preoperative and postoperative IOP between the measured parameters with UBM showed no statistically significant correlation.Conclusions. Gases cause more morphological changes in the anterior segment structures. It is thought that complications such as increased intraocular pressure can be seen more frequently for this reason.
