Scleral Buckling with Viscoelastics or Gas Injection for Bulging Retinal Detachments: A Retrospective Cohort Study

Objective. To examine the use of a viscoelastic agent instead of air in the vitreous cavity during surgery for scleral buckling. Methods. This was a retrospective cohort study of patients who underwent scleral buckling surgery for bulging rhegmatogenous retinal detachment (RRD) at Ningbo Eye Hospital from 07/2016 to 12/2019. The patients were grouped into drainage, air injection, cryotherapy and explant (DACE) and drainage, viscoelastic injection, cryotherapy, and explant (DVCE) groups, which were comparatively assessed. Results. There were 25 and 22 patients in the DVCE and DACE groups, respectively. The surgery was significantly shorter with DVCE than DACE ( P < 0.05 ), with less intraoperative external pressure adjustment ( P < 0.05 ). BCVA was lower in the DVCE group at 1 week compared with the DACE group ( P < 0.05 ). Successful retinal reattachment was observed in 92.0% and 81.8% of the DVCE and DACE groups, respectively ( P < 0.05 ). Cases requiring laser replenishing after the operation were less in the DVCE group compared with the DACE group ( P < 0.05 ). There were no differences in complications and intraocular pressure between the two groups (all P < 0.05 ). Conclusion. DVCE has better operative characteristics and faster vision recovery than DACE, with similar outcomes.

Anatomical Success

Introduction: The aim of this study was to present the clinical presentation and short-term outcomes of uncomplicated rhegmatogenous retinal detachment managed by pneumatic retinopexy at a tertiary eye hospital in western Saudi Arabia. Materials and methods: This one-armed retrospective cohort study evaluated selected cases of rhegmatogenous retinal detachment managed by pneumatic retinopexy between 2017 and 2018. Data were collected on patient demographics, preoperative ophthalmic assessment, surgical details, follow up at six months postoperatively, complications and the need for additional surgery. Anatomic success was defined as retinal attachment at 6 months and functional success was defined as vision >20/200 at six months postoperatively. The association of lens status and concomitant laser treatment to anatomical success rates were evaluated. Results: The study sample consisted of 15 eyes with rhegmatogenous retinal detachment in the upper quadrant. In 14 cases, C3F8 gas was used. Anatomic and functional success was noted in 73.3% [95% confidence interval (CI) 51.0: 95.7] and 86.7% (95% CI 69.2; 100) of eyes, respectively. The association between anatomical success and lens status was not significant [RR = 4.5 (95% CI 0.6 ; 37.5), P=0.1]. There was no significant association between anatomical success and concomitant laser treatment. [RR = RR = 1.7 (95% CI 0.7 ; 4.0), P=0.2]. A 2nd retinal surgery was not required in 33.3% of eyes (95% CI 9.5 ; 57.2). Conclusion: If stringent selection criteria are used for managing rhegmatogenous retinal detachment with pneumatic retinopexy, anatomical and functional success by six months postoperatively is achieved in the majority of cases. Additional surgeries could further improve outcomes.

Improved Outcomes

Background Neodymium-doped yttrium aluminum garnet laser goniopuncture is an adjuvant procedure for nonpenetrating deep sclerectomy. We investigated optimal laser goniopuncture timing and the effect of laser iridoplasty on success rates Methods This single-center retrospective cohort study compared intraocular pressure control in patients with early versus late laser goniopuncture after nonpenetrating deep sclerectomy and evaluated the effects of laser iridoplasty pretreatment. A 3-month cut-off was used to define early versus late laser goniopuncture. The primary outcome was the proportion of patients maintaining intraocular pressure control according to definitions of complete (no medications) and qualified (with medications) success at 15, 18, and 21 mmHg thresholds. Data were analyzed using right-censored Kaplan–Meier estimation and log-rank testing Results A total of 124 eyes of 124 patients were analyzed. Complete success rates after 3 years were 9.2%, 14.6%, and 23.3% for early laser goniopuncture and 21.8%, 26.0%, and 55.4% for late laser goniopuncture for 15, 18, and 21 mmHg, respectively (all p < .01). Qualified success rates after 3 years were 16.6%, 24.8%, and 40.9% for early laser goniopuncture and 21.5%, 56.1%, and 69.6% for late laser goniopuncture for 15, 18, and 21 mmHg, respectively ( p = .096, .0026, .0061). Late laser goniopuncture was associated with decreased risk of iris incarceration and bleb collapse. Iridoplasty pretreatment was not associated with improved outcomes Conclusion Late laser goniopuncture (3-month cut-off) was associated with better intraocular pressure control and less adverse events than early laser goniopuncture.

Introduction: Cataract is the leading cause of preventable blindness worldwide. It is caused by the degeneration and opacification of the lens fibres. Phacoemulsification is the current treatment modality available for cataract. However, there is a possibility of an increase in the anterior chamber depth after phacoemulsification. This occurs as a result of the removal of the bulky lens matter and implantation of a thin intraocular lens, thereby reducing the intraocular pressure. Aim: To compare the preoperative and postoperative Intraocular Pressure (IOP) changes and the factors associated with intraocular pressure changes among patients who underwent phacoemulsification in a Tertiary Care Centre in Kerala. Materials and Methods: A retrospective cohort study was carried out among 610 patients, who underwent phacoemulsification surgery from January 1st, 2017 to December 31st, 2017. Using a checklist, the following data such as age, sex, Date of Surgery, Last recorded preoperative intraocular pressure of both eyes, First recorded Postoperative intraocular pressure of both eyes any time after 3 months, Axial length, Grade of cataract and comorbidities like diabetes, hypertension, dyslipidaemia, glaucoma and Coronary Artery Disease (CAD) was obtained from the hospital Information System. Data collected was entered into an MS Excel and was analysed using SPSS version 20. Frequency and percentages were calculated and association assessed using Chi-square test. Paired t-test was applied to find the mean changes in the IOP levels and p-value was ≤0.05, thus significant. Results: It was observed that there was a mean reduction of 7.907 mmHg in ocular hypertensives when compared to ocular normotensives following phacoemulsification. This finding was found to be statistically significant (p-value <0.001). There was association between grade of cataract and change in IOP which was significant with a p-value of 0.031. Conclusion: Phacoemulsification is the treatment of choice in patients with cataract. In the study, it was found that ocular hypertensives who underwent phacoemulsification had a significant drop in intraocular pressure post-surgery. Phacoemulsification can be employed in patients who have both ocular hypertension and cataract. This procedure can improve vision and in addition to having a positive effect on IOP reduction.
