ObjectiveTo observe the demographic data, disease composition and convenience of remote consultation in ophthalmology. MethodsA retrospective study. From 2015 to 2021, the demographic data, changing trends, disease classification of teleconsultation patients, and hospitals participating in teleconsultation, and the waiting time of patients for teleconsultation was analyzed retrospectively; remote consultation physician level composition and other data was analyzed. ResultsDuring the 7-year period, 1 216 patients with remote consultation were obtained through the platform of the telemedicine center. Among them, there were 680 males and 536 females; the average age was 50.8 years. In 2016 and 2017, the number of patients participating in telemedicine consultations reached a peak of 260 and 221 cases, respectively. Among the ophthalmic diseases, there were 490 cases (40.30%, 490/1 216) of retinal and optic nerve-related diseases, 212 cases (17.43%, 212/1 216) of ocular trauma. 678 cases (56.27%, 678/1 205) of remote consultation waiting time were less than 24 hours, 991 cases (82.24%, 991/1 205) were less than 48 hours. Among the physicians who participated in the remote consultation, there were 733 chief physicians (60.3%, 733/1 216) and 466 deputy chief physicians (38.3%, 466/1 216). ConclusionsDuring the seven-year period from 2015 to 2021, there are relatively few patients with ophthalmology teleconsultation; retinal and optic nerve-related diseases accounted for a high proportion. Remote consultation has high convenience.
Objective To evaluate the efficacy and safety of ophthalmic viscosurgical device (OVD)-assisted non-gas dependent pars plana vitrectomy (PPV) combined with an inverted internal limiting membrane (ILM) flap for the treatment of idiopathic macular hole (IMH). MethodsA retrospective cohort study. From June 2023 to February 2024, 33 patients (33 eyes) diagnosed with IMH in Department of Ophthalmology of Changshu Second People’s Hospital were included in the study. Best corrected visual acuity (BCVA) and optical coherence tomography (OCT) examinations were performed on all affected eyes before surgery. BCVA examination was conducted using the international standard visual acuity chart, and the results were converted into the logarithm of the minimum angle of resolution (logMAR) visual acuity. The minimum diameter of the hole was measured using OCT. All affected eyes received standard 25G PPV treatment through the three channels of the flat part of the ciliary body. According to the surgical methods, they were divided into two groups: the OVD-assisted non-gas-dependent PPV combined with internal limiting membrane inversion and coverage treatment group (OVD group, 17 cases and 17 eyes) and the heavy water-assisted gas-dependent PPV combined with internal limiting membrane inversion and coverage treatment group (heavy water group, 16 cases and 16 eyes). Postoperatively, patients in the OVD group were not required to maintain a strict specific position, whereas those in the heavy water group needed to remain in a prone position for one week. The follow-up time points after the operation were 1 week, 1 month and 3 months. The main observation indicators included BCVA, intraocular pressure, hole closure rate and closure morphology of the two groups, as well as the occurrence of complications. The independent sample t test was used for comparison between groups. Pearson correlation analysis was used for the correlation between BCVA at 3 months after surgery and the minimum diameter of the surgical hole and BCVA before surgery. ResultsThree months after the operation, the rate of hole closure in the OVD group and the heavy water group was 17 (100.0%, 17/17) and 15 (93.8%, 15/16) eyes, respectively. There was no statistically significant difference in the hole closure rate (χ2=1.090) and closure type (Z=?0.780) between the two groups (P＞0.05). Compared with before the operation, the logMAR BCVA at each time point after the operation in the OVD group and the heavy water group was significantly improved (F=2.353, 1.375; P＜0.05). One week after the operation, the BCVA in the OVD group was significantly better than that in the heavy water group (t=-3.760, P＜0.01). In terms of intraocular pressure, compared with the baseline value before the surgery, there was a statistically significant difference in the OVD group one week after the surgery (Z=?3.454, P＜0.05). There were statistically significant differences in the heavy water group at 1 week, 1 month and 3 months after the operation (Z=?5.066, ?3.423, ?2.739; P＜0.05). After the operation, one eye in the heavy water group had high intraocular pressure, which returned to normal after combined treatment with intraocular pressure-lowering drugs. No ocular or systemic complications occurred in the OVD group. The results of the correlation analysis showed that postoperative BCVA was correlated with the minimum diameter of the surgical hole and BCVA before the surgery (r=0.543, 0.658; P＜0.05). ConclusionsThe treatment of IMH with OVD-assisted non-gas-dependent PPV combined with internal limiting membrane flip coverage has a good effect. It helps promote the early recovery of macular morphology and visual function after surgery, and at the same time can avoid the maintenance of forced position and reduce perioperative risks.
Mast cell (MC) play a crucial role in non-allergic fundus diseases, including uveitis, diabetic retinopathy, and age-related macular degeneration. MCs can profoundly influence the pathological processes of these diseases by regulating inflammatory responses, promoting angiogenesis, and facilitating tissue remodeling through the degranulation and release of mediators such as histamine, cytokines, and enzymes. The application of MC-associated inhibitors has been shown to effectively mitigate or inhibit the progression of these pathologies, offering a promising strategy for treating ocular diseases. Understanding the current state of MC research in fundus diseases will enhance our insight into their role in the pathophysiological mechanisms of these conditions and encourage further research aimed at providing more effective treatment options for patients.
Obstructive sleep apnea hypopnea syndrome (OSAHS) is a disease in which apnea and hypopnea occur during sleep, and the main symptoms are sleep snoring. OSAHS is not only closely related to the occurrence of various eye diseases, but also the severity of OSAHS can affect the progression of related eye diseases. At present, continuous positive airway pressure (CPAP) is an effective means to treat OSAHS, and the progression of related eye diseases has been improved correspondingly after CPAP treatment. In the future, it is necessary to further study the pathogenesis of OSAHS and enrich the research evidence of the association between OSAHS and eye diseases, so as to provide more comprehensive theoretical evidence for the prevention and treatment of OSAHS-related eye diseases.
There has been ongoing progress in the new technique and equipment in vitreoretinal surgery in recent years, contributing to the improvement of treatment of various vitreoretinal diseases. The application of 3D heads-up display viewing system (3D viewing system) has been one of the most fascinating breakthroughs in vitreoretinal surgery. Unlike the traditional method in which the surgeons have to look through the microscope eyepieces, this system allows them to turn their heads up and operate with their eyes on a high-definition 3D monitor. It provides the surgeons with superior visualization and stereoscopic sensation. And increasing studies have revealed it to be as safe and effective as the traditional microscopic system. Furthermore, the surgeons can keep a heads-up position in a more comfortable posture and lesson the pressure on cervical spine. Meanwhile, 3D viewing system makes it easier for the teaching and learning process among surgeons and assistants. However, there are still potential disadvantages including the latency between surgeon maneuver and visualization on the display, learning curves and cost. We hope that the 3D viewing system will be widely used and become a useful new tool for various vitreoretinal diseases in the near future with rapid development in the technology and constant upgrade of the system.
Objective To investigate the characteristics of ultrasonogram of eyes with silicon oil tamponade. Methods Forty-seven patients (47 eyes) who had undergone the operation of silicon-oil removing were examined by A-(to determine the length of ocular axis) and B-scan before and after the operation respectively. The length of ocular axis and cubage of vitreous chamber were detected and the characteristics of the ultrasonograms were observed according to the default parameters of ultrasonograph. Results The results of A-scan showed that the preoperative axial length was 1.465 times of the postoperative one in the eyes without lens, and 1.284 times in eyes with lens; after modified the parameter according to the acoustic velocity, the preoperative axial length was (0.78±0.34) mm longer than the postoperative one in the eyes without lens, and (0.56±0.32) mm in eyes with lens. The results of A-scan showed that the cubage of vitreous chamber enlarged obviously in eyes with silicon oil tamponade, and the acoustic features included complete filling and partial filling according to the amount of silicon oil. Several arc echoes at the posterior segment of eye were detected in the silicon-oil-filling eyes with retinal detachment. Conclusion In the silicon-oil-filling eyes with lengthened ocular axis, the characteristics of B-scan images are affected by acoustic velocity through silicon oil, the amount of silicon oil capacity and the emulsification of silicon oil.
